DEPARTMENT OF AGRICULTURE
7 CFR Part 927

[Docket No. AO-99-A7; FV96-927-1]

Winter Pears Grown in Oregon, Washington, and California; 
Hearings on Proposed Amendment of Marketing Order No. 927

AGENCY: Agricultural Marketing Service, USDA.

ACTION: Notice of public hearings on proposed rulemaking.

-----------------------------------------------------------------------

SUMMARY: Notice is hereby given of public hearings to consider amending 
Marketing Agreement and Order No. 927 (order). The order regulates the 
handling of winter pears grown in Oregon, Washington, and California. 
The purpose of the hearings is to receive evidence on proposed 
amendments to provisions of the order. With the exception of a proposal 
submitted by the Fruit and Vegetable Division, Agricultural Marketing 
Service (AMS), to make conforming changes and necessary revisions, the 
proposed amendments were submitted by the Winter Pear Control Committee 
(Committee), the agency responsible for the local administration of the 
order. The proposals would remove the State of California from the 
order and make related changes to the key provisions concerning the 
production area, districts and establishment and membership of the 
Committee. Another proposal would allow use of ``Telecopiers'' in the 
mail voting procedures. The Committee believes that the proposed 
changes would improve the administration, operation, and functioning of 
the order.

DATES: The hearings will begin July 9, 1996, at the Red Lion Inn, 1401 
Arden Way, Sacramento, California, and July 10, 1996, at the Holiday 
Inn Airport, 8439 N. East Columbia Blvd., Portland, Oregon. Both 
hearing sessions will begin at 9:00 am.

FOR FURTHER INFORMATION CONTACT: Britthany E. Beadle, Marketing 
Specialist, Marketing Order Administration Branch, Fruit and Vegetable 
Division, AMS, USDA, Room 2523-S., P.O. Box 96456, Washington, DC 
20090-6456; telephone: (202) 720-5127 or FAX (202) 720-5698; or Teresa 
Hutchinson, Marketing Specialist, Northwest Marketing Field Office, 
Fruit and Vegetable Division, AMS, USDA, 1220 S.W. Third Avenue, room 
369, Portland, OR 97204-2807; telephone: (509) 326-2724 or FAX (509) 
326-7440.

SUPPLEMENTARY INFORMATION: This action is governed by the provisions of 
sections 556 and 557 of title 5 of the United States Code and is 
therefore excluded from the requirements of Executive Order 12866. The 
hearings are called pursuant to the provisions of the Agricultural 
Marketing Agreement Act of 1937 (Act), as amended (7 U.S.C. 601-674), 
and the applicable rules of practice and procedure governing the 
formulation of marketing agreements and orders (7 CFR part 900).
    The Regulatory Flexibility Act (95 U.S.C. 601 et seq.) seeks to 
ensure that within the statutory authority of a program, the regulatory 
and informational requirements are tailored to the size and nature of 
small businesses. Interested persons are invited to present evidence at 
the

[[Page 33048]]

hearings on the regulatory and informational impact of the proposed 
amendments on small businesses.
    The notice of hearing herein has been reviewed under Executive 
Order 12778, Civil Justice Reform. It is not intended to have 
retroactive effect. The notice of hearing would not preempt any State 
or local laws, regulations, or policies, unless they present an 
irreconcilable conflict with this notice to consider an amendment.
    The Act provides that administrative proceedings must be exhausted 
before parties may file suit in court. Under section 608c(15)(A) of the 
Act, any handler subject to an order may file with the Secretary a 
petition stating that the order, any provision of the order, or any 
obligation imposed in connection with the order is not in accordance 
with law and requesting a modification of the order or to be exempted 
therefrom. A handler is afforded the opportunity for a hearing on the 
petition. After the hearing, the Secretary would rule on the petition. 
The Act provides that the district court of the United States in any 
district in which the handler is an inhabitant, or has his or her 
principal place of business, has jurisdiction in equity to review the 
Secretary's ruling on the petition, provided an action is filed not 
later than 20 days after the date of the entry of the ruling.
    The Committee submitted the proposed amendment to remove California 
from the winter pear order. The suggested changes are as follows: (1) 
Revise the definition of ``production area'' to mean only the States of 
Oregon and Washington; (2) revise ``district'' by removing California 
and have only those districts designated in the States of Oregon and 
Washington; (3) revise ``establishment and membership'' of the 
Committee to be consistent with the reduction in size of the regulated 
production area; (4) revise ``procedure of Control Committee'', ``(a) 
quorum and voting'', so that the number of members present for a quorum 
and voting is consistent with Committee representation and amend ``(b) 
mail voting'', to allow for the use of ``telecopiers''; and (5) revise 
the definition of ``pears'' to exclude pears produced in California. 
These proposals were submitted by the Committee, which works with the 
Department in administering the order. These proposals have not 
received the approval of the Secretary of Agriculture.
    The Committee believes that the proposed changes would improve the 
administration, operation, and function of the winter pear marketing 
order.
    In addition, proposals submitted by the Fruit and Vegetable 
Division, AMS, are included to make such changes as may be necessary to 
the order to conform with any amendment thereto that may result from 
the hearing.
    Public hearings are being held for the purpose of: (i) receiving 
evidence about the economic and marketing conditions which relate to 
the proposed amendments of the order; (ii) determining whether there is 
a need for the proposed amendments to the order; and (iii) determining 
whether the proposed amendments or appropriate modifications thereof 
will tend to effectuate the declared policy of the Act.
    All persons wishing to submit written material as evidence at the 
hearing should submit at least four copies of such material and should 
be present at the hearing to present oral testimony concerning the 
material.
    From the time the notice of hearing is issued and until the 
issuance of a final decision in this proceeding, Department employees 
involved in the decisional process are prohibited from discussing the 
merits of the hearing issues on an ex parte basis with any persons 
having an interest in the proceeding. The prohibition applies to 
employees in the following organizational units: Office of the 
Secretary of Agriculture; Office of the Administrator, Agricultural 
Marketing Service; Office of the General Counsel, and the Fruit and 
Vegetable Division, Agricultural Marketing Service.
    Procedural matters are not subject to the above prohibition and may 
be discussed at any time.

[CC Docket No. 96-128; DA 96-983]

Pay Telephone Reclassification and Compensation Provisions of the 
Telecommunications Act of 1996

AGENCY: Federal Communications Commission.

ACTION: Proposed rule; extension of time.

-----------------------------------------------------------------------

SUMMARY: In this Order, we are extending the comments and reply 
comments deadlines in order to grant to the parties more time to 
address all issues raised in the Notice of Proposed Rulemaking. This 
Order is issued on the Commission's own motion because of the 
relatively short time that was accorded to the parties to comment on 
the important issues.

DATES: Comments due: July 1, 1996; Reply Comments due: July 15, 1996.

ADDRESSES: In addition to filing comments with the Secretary, a copy of 
any comments on the information collections contained herein should be 
submitted to Dorothy Conway, Federal Communications Commission, Room 
234, 1919 M Street, N.W., Washington, DC 20554, or via the Internet to 
[email protected] and to Timothy Fain, OMB Desk Officer, 10236 NEOB, 725 
- 17th Street, N.W., Washington, DC 20503 or via the Internet to

SUPPLEMENTARY INFORMATION:

Order

Adopted: June 20, 1996; Released: June 20, 1996.

    1. On June 14, 1996, the American Public Communications Council 
(``APCC'') filed a motion asking that we extend the deadline for filing 
comments in the above-captioned proceeding 1 from June 27, 1996, 
to July 1, 1996, a period of four days. APCC also requests a 
corresponding extension of the due date for reply comments from July 8, 
1996, to July 12, 1996. In support of its motion, APCC states that 
virtually every issue in the proceeding vitally affects its members and 
that, as a result, additional days are required to effectively prepare 
comments.2 Also on June 14, 1996, Southwestern Bell Telephone 
Company (``SWBT'') filed a motion for an extension of the deadline for 
reply comments to July 12, 1996, although it does not request a change 
in the deadline for the initial comment cycle. SWBT argues that due to 
the forthcoming federal holiday, there will not be a sufficient number 
of business days for parties to respond adequately to the initial 
comments.

    \1\ Notice of Proposed Rulemaking, FCC 96-254 (rel. Jun. 6, 
1996); 61 FR 31481, June 20, 1996.
    \2\ As a national trade association of independent pay telephone 
companies, APCC claims that the comment process will require 
coordination with member companies and allied state associations. 
APCC claims that this process cannot be completed effectively in the 
time allotted.
---------------------------------------------------------------------------

    2. It is the policy of the Commission that extensions of time are 
not routinely granted.3 However, in light of the important issues 
presented in this proceeding and the relatively short period of time 
accorded to the parties to comment on those issues, we believe that the 
public interest would be served by granting all parties a brief 
extension of the deadlines for the comments and reply comments. While 
we take this action on our motion, we nevertheless believe that this 
Order will grant relief that is substantially similar to that requested 
by APCC and SWBT.
---------------------------------------------------------------------------

    \3\ See 47 CFR Sec. 1.46(a).
---------------------------------------------------------------------------

    3. Accordingly, it is ordered, pursuant to Sections 4(i), 4(j), and 
5(c) of the Communications Act of 1934, as amended, 47 U.S.C. 154(i), 
154(j), and 155(c), and the authority delegated thereunder pursuant to 
Sections 0.91 and 0.291 of the Commission's rules, 47 CFR Secs. 0.91 
and 0.291, that the deadline for filing comments in the above-captioned 
proceeding is extended to July 1, 1996, and the deadline for filing 
reply comments is extended to July 15, 1996. Because they concern 
issues that are now moot, the motions of APCC and SWBT for an extension 
of time are dismissed.

Copper 8-quinolinolate; Proposed Tolerance Exemption

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: This document proposes that residues of copper 8-quinolinolate 
(CAS Reg. No. 10380-28-6) be exempted from the requirement of a 
tolerance when used as an inert ingredient (preservative) in 
pesticidally treated paper products used on growing crops. This 
proposed regulation was requested by American Agricultural Services 
Inc., pursuant to the Federal Food, Drug, and Cosmetic Act (FFDCA).

SUPPLEMENTARY INFORMATION: American Agricultural Services, Inc., 404 E. 
Chatham St., Cary, NC 27511, has submitted pesticide petition (PP) 
5E4472 to EPA requesting that the Administrator, pursuant to section 
408(e) of the Federal Food, Drug, and Cosmetic Act, 21 U.S.C. 346a(e), 
propose to amend 40 CFR 180.1001(d) by establishing an exemption from 
the requirement of a tolerance for copper 8-quinolinolate (CAS Reg. No. 
10380-28-6) when used as an inert ingredient (preservative) in 
pesticidally treated paper products used on growing crops under 40 CFR 
180.1001(d).
    Inert ingredients are all ingredients that are not active 
ingredients as defined in 40 CFR 153.125 and include, but are not 
limited to, the following types of ingredients (except when they have a 
pesticidal efficacy of their own): solvents such as alcohols and 
hydrocarbons; surfactants such as polyoxyethylene polymers and fatty 
acids; carriers such as clay and diatomaceous earth; thickeners such as 
carrageenan and modified cellulose; wetting, spreading, and dispersing 
agents; propellants in aerosol dispensers; microencapsulating agents; 
and emulsifiers. The term ``inert'' is not intended to imply 
nontoxicity; the ingredient may or may not be chemically active.
    The data submitted in the petition and other relevant material have 
been evaluated. As part of the EPA policy statement on inert 
ingredients published in the Federal Register of April 22, 1987 (52 FR 
13305), the Agency set forth a list of studies which would generally be 
used to evaluate the risks posed by the presence of an inert ingredient 
in a pesticide formulation. However, where it can be determined without 
that data that the inert ingredient will present minimal or no risk, 
the Agency generally does not require some or all of the listed studies 
to rule on the proposed tolerance or exemption from the requirement of 
a tolerance for an inert ingredient. The Agency has decided that no 
data, in addition to that described below, for copper 8-quinolinolate 
will need to be submitted. The rationale for this decision is described 
below:
    1. Copper 8-quinolinolate is cleared by the U.S. Food and Drug 
Administration (FDA) as an indirect food additive for use as a 
component in food packaging adhesives [21 CFR 175.105(c)]; in paper and 
paperboard in contact with aqueous and fatty foods (21 CFR 176.170); 
and in paper and paperboard in contact with dry foods (21 CFR 176.180).
    2. Copper 8-quinolinolate is currently registered under the Federal 
Insecticide, Fungicide, and Rodenticide Act (FIFRA) as a fungicide/
preservative for (a) wood treatment including food contact surfaces, 
for fruit and vegetable, food and feed containers, and bushel baskets 
to protect the wood against mold, mildew, wood rot/decay fungi and wood 
stain fungi; (b) agricultural paper mulch to protect against mildew, 
fungal rot/decay (c) potato storage, handling, cutting and planting 
equipment to protect against bacterial ring rot; and (d) for fabric, 
cardboard and paper to protect against mold/mildew.
    3. The toxicity data available from the open literature indicates 
that copper 8-quinolinolate has a moderate acute toxicity in mice when 
administered by intraperitoneal injection; it gave negative results in 
a limited mice oral carcinogenicity studies; and has weak mutagenicity 
in a bacterial Ames test.
    Based on the expected low exposure and the similarity of the 
proposed use pattern to the existing use, as an indirect food additive, 
already approved by the FDA, and as an active ingredient registered 
under FIFRA as preservative for wood, cardboard and paper intended for 
storage and handling potatoes, fruits and vegetables, and the available 
toxicology data, the EPA has found that, when used in accordance with 
good agricultural practice, this ingredient is useful and a tolerance 
is not necessary to protect the public health. Therefore, EPA proposes 
that the exemption from the requirement of a tolerance be established 
as set forth below.
    Any person who has registered or submitted an application for 
registration of a pesticide, under the Federal Insecticide, Fungicide, 
and Rodenticide Act (FIFRA) as amended, which contains any of the 
ingredients listed herein, may request within 30 days after publication 
of this document in the Federal Register that this proposal be referred 
to an Advisory Committee in

[[Page 33059]]

accordance with section 408(e) of FFDCA.
    Interested persons are invited to submit written comments on the 
proposed regulation. Comments must bear a notation indicating the 
docket number, [PP 5E4472/P667].
    A record has been established for this rulemaking under docket 
number [PP 5E4472/P667] (including comments and data submitted 
electronically as described below). A public version of this record, 
including printed, paper versions of electronic comments, which does 
not include any information claimed as CBI, is available for inspection 
from 8 a.m. to 4:30 p.m., Monday through Friday, excluding legal 
holidays. The public record is located in Room 1132 of the Public 
Response and Program Resources Branch, Field Operations Division 
(7506C), Office of Pesticide Programs, Environmental Protection Agency, 
Crystal Mall #2, 1921 Jefferson Davis Highway, Arlington, VA.
    Electronic comments can be sent directly to EPA at:
    [email protected]

    Electronic comments must be submitted as an ASCII file avoiding the 
use of special characters and any form of encryption.
    The official record for this rulemaking, as well as the public 
version, as described above will be kept in paper form. Accordingly, 
EPA will transfer all comments received electronically into printed, 
paper form as they are received and will place the paper copies in the 
official rulemaking record which will also include all comments 
submitted directly in writing. The official rulemaking record is the 
paper record maintained at the Virginia address in ``ADDRESSES'' at the 
beginning of this document.
    The Office of Management and Budget has exempted this proposed rule 
from the requirements of section 3 of Executive Order 12866.
    This action does not impose any enforceable duty, or contain any 
``unfunded mandates'' as described in Title II of the Unfunded Mandates 
Reform Act of 1955 (Pub. L. 104-4), or require prior consultation as 
specified by Executive Order 12875 (58 FR 58093, October 28, 1993), 
entitled Enhancing the Intergovernmental Partnership, or special 
consideration as required by Executive Order 12898 (59 FR 7629, 
February 16, 1994). Pursuant to the requirements of the Regulatory 
Flexibility Act (5 U.S.C. 601-612), the Administrator has determined 
that regulations establishing new tolerances or raising tolerance 
levels or establishing exemptions from tolerance requirements do not 
have a significant economic impact on a substantial number of small 
entities. A certification statement explaining the factual basis for 
this determination was published in the Federal Register of May 4, 1981 
(46 FR 24950).

National Emission Standards for Hazardous Air Pollutants; 
National Emission Standard for Radon Emissions From Phosphogypsum 
Stacks

AGENCY: Environmental Protection Agency.

ACTION: Notice of public hearing.

-----------------------------------------------------------------------

SUMMARY: The Office of Radiation and Indoor Air, Radiation Protection 
Division will hold a public hearing on the proposed rule for 40 CFR 
Part 61, Subpart R, (Subpart R) the National Emission Standard for 
Radon Emissions from Phosphogypsum Stacks--Notice of Reconsideration. 
This proposed rule was in response to The Fertilizer Institute's 
Petition for Reconsideration of the National Emission Standards for 
Hazardous Air Pollutants regulating radon emissions from phosphogypsum 
stacks. EPA partially granted and partially denied the TFI petition for 
reconsideration. Pursuant to that decision, EPA is convening this 
rulemaking to reconsider 40 CFR 61.205, the provision of the final rule 
which governs distribution and use of phosphogypsum for research and 
development, and the methodology utilized under 40 CFR Section 61.207 
to establish the average radium-226 concentration for phosphogypsum 
removed from a phosphogypsum stack.
    In the May 8, 1996 Federal Register notice, EPA stated that the 
hearing, if requested, would be in Washington, D.C.; however, in order 
to provide the public with a more convenient location setting, the 
hearing will be held in Orlando, Florida.

DATES: The hearing will be held on Thursday, August 1, 1996, beginning 
at 9:00 am and will continue until concluded. In addition, pursuant to 
Section 307(d)(5), the public may submit rebuttal and supplemental 
information to the docket for thirty (30) days after the public 
hearing. This comment period will end on August 31, 1996.

ADDRESSES: The hearing will take place at the Holiday Inn International 
Drive Resort, 6515 International Drive, Orlando, Florida 32819. 
Comments should be submitted (in duplicate) to: Central Docket Section 
(6101), Environmental Protection Agency, ATTN: Air Docket No. 94-57, 
Washington, D.C. 20460. The docket is available for public inspection 
between the hours of 8:00 am and 5:30 pm, Monday through Friday, in 
Room M1500 of Waterside Mall, 401 M Street, SW, Washington, DC 20460. A 
reasonable fee may be charged for copying. The FAX number is (202) 260-
4400.

Agency, Washington, DC 20460, (202) 233-9762.

SUPPLEMENTARY INFORMATION: This meeting is open to all members of the 
public. Requests to attend and participate in the public hearing on the 
proposed rule for 40 CFR Part 61, Subpart R, the National Emission 
Standard for Radon Emissions from Phosphogypsum Stacks--Notice of 
Reconsideration (61 FR 20775, No. 90, May 8, 1996), should be made by

FEDERAL COMMUNICATIONS COMMISSION

47 CFR Chapter I

[General Docket No 96-113; FCC 96-216]

Identifying and Eliminating Market Entry Barriers for Small 
Businesses

AGENCY: Federal Communications Commission.

ACTION: Proposed rule; notice of inquiry.

-----------------------------------------------------------------------

SUMMARY: The attached Notice of Inquiry (NOI) commences a proceeding to 
examine barriers to small business entry into the telecommunications 
marketplace. Section 101 of the Telecommunications Act of 1996 (1996 
Telecommunications Act) adds new Section 257 to the Communications Act, 
which requires the Commission, within 15 months after enactment, to 
complete a proceeding to identify and eliminate market entry barriers 
for entrepreneurs and other small businesses in the provision and 
ownership of telecommunications services and information services, or 
in the provision of parts or services to providers of 
telecommunications services and information services. Through this NOI, 
the Commission initiates an omnibus Section 257 proceeding and will 
undertake specific initiatives that further the objective of reducing 
market entry barriers for small businesses. The record developed in 
connection with these intiatives also will, assist us in achieving our 
mandate under Section 309(j) of the Communications Act of 1934 to 
disseminate licenses for auctionable spectrum-based services to small 
businesses, rural telephone companies, and businesses owned by women 
and minorities, as well as in fulfilling our general obligation to 
serve the public interest.

DATES: Comments must be submitted on or before July 24, 1996 and reply 
comments are due on or before August 23, 1996.

ADDRESSES: Comments and reply comments may be mailed to the Office of 
the Secretary, Federal Communications Commission, Washington, D.C.

I. Introduction

    1. Section 101 of the Telecommunications Act of 1996 (1996 
Telecommunications Act),\1\ adds new Section 257 to the Communications 
Act of 1934.\2\ Section 257 requires the Commission, within 15 months 
after enactment, to complete a proceeding ``for the purpose of 
identifying and eliminating, by regulations pursuant to its authority 
under this Act * * * market entry barriers for entrepreneurs and other 
small businesses in the provision and ownership of telecommunications 
services and information services, or in the provision of parts or 
services to providers of telecommunications services and information 
services.'' \3\ In implementing Section 257, the Commission must 
``promote the policies and purposes of this Act favoring diversity of 
media voices, vigorous economic competition, technological advancement, 
and promotion of the public interest, convenience and necessity.'' \4\ 
Every three years following the completion of the market entry barriers 
proceeding, the Commission must report to Congress on regulations that 
have been issued to eliminate barriers and any statutory barriers that 
the Commission recommends be eliminated.\5\
---------------------------------------------------------------------------

    \1\ Telecommunications Act of 1996, Public Law No. 104-104, 110 
Stat. 56 (1996).
    \2\ 47 U.S.C. 151 et seq.
    \3\ 47 U.S.C. 257(a).

    \5\ 47 U.S.C. 257(c).
---------------------------------------------------------------------------

    2. This Notice of Inquiry (NOI) commences the Commission's omnibus 
Section 257 proceeding. We also will undertake specific initiatives 
that further the objective of Section 257 to reduce market entry 
barriers for small businesses. The record developed in connection with 
these initiatives also will assist us in achieving our mandate under 
Section 309(j) of the Act \6\ to disseminate licenses for auctionable 
spectrum-based services to small businesses, rural telephone companies, 
and businesses owned by women and minorities, as well as in fulfilling 
our general obligation to serve the public interest.\7\
---------------------------------------------------------------------------

    \6\ 47 U.S.C. 309(j).
    \7\ See, e.g., 47 U.S.C. Sec. 214 (Commission must certify that 
public convenience or necessity requires construction or extension 
of lines); 47 CFR Sec. 303 (Commission must regulate radio as public 
interest, convenience or necessity requires); 47 U.S.C. 307(a) 
(Commission must grant radio licenses that serve the public 
convenience, interest, or necessity).
---------------------------------------------------------------------------

    3. We also inquire whether small businesses owned by minorities or 
women face unique entry barriers. We explore this area because the 
legislative history of Section 257 suggests that Congress was concerned 
about the underrepresentation of minority or women-owned small 
businesses in the telecommunications market and sought to increase 
competition by diversifying ownership.\8\ In addition, Section 309(j) 
specifically requires that we further opportunities for businesses 
owned by women and minorities in the provision of spectrum-based 
services, because a portion of small telecommunications businesses 
under Section 257 are owned by women and minorities, and because

[[Page 33067]]

evidence suggests that these entities encounter unique market barriers.
---------------------------------------------------------------------------

    \8\ The Congressional Record provides:
    [W]hile we should all look forward to the opportunities 
presented by new, emerging technologies, we cannot disregard the 
lessons of the past and the hurdles we still face in making certain 
that everyone in America benefits equally from our country's maiden 
voyage into cyberspace. I refer to the well-documented fact that 
minority and women-owned small businesses continue to be extremely 
under represented in the telecommunications field. * * * Underlying 
this amendment [Section 257] is the obvious fact that diversity of 
ownership remains a key to the competitiveness of the U.S. 
telecommunications marketplace.
    142 Cong. Rec. H1141 at H1176-77 (daily ed. Feb. 1, 1996) 
(statement of Rep. Collins).
---------------------------------------------------------------------------

II. Background

    4. The primary purpose of this inquiry is to fulfill our mandate 
under Section 257 to identify and eliminate market barriers for small 
businesses in the provision and ownership of telecommunications and 
information services, and in the provision of parts or services to 
providers of telecommunications services and information services. We 
interpret ``market entry barriers'' to include obstacles that deter 
entrepreneurs from forming small businesses, barriers that impede entry 
into the telecommunications market by existing small businesses, and 
obstacles that small telecommunications businesses face in providing 
service or expanding within the telecommunications industry, e.g., 
those that inhibit a paging company from expanding into a new 
geographic area or new service such as cellular.
    5. The legislative history of Section 257 essentially parallels the 
language of the enacted provision. The Conference Report states: ``The 
conference agreement adopts the House provisions with minor 
modifications as a new Section 257 of the Communications Act.'' \9\ 
There was no provision in the Senate bill and the House amendment 
stated: ``Section 250 [now Section 257] requires the Commission to 
adopt rules that identify and eliminate market entry barriers for 
entrepreneurs and small businesses in the provision and ownership of 
telecommunications and information services. The Commission must review 
these rules and report to Congress every three years on how it might 
prescribe or eliminate rules to promote the purposes of this section.''

Statement of the Committee of Conference at 23.
    \10\ 142 Cong. Rec. H1078-03 at H1113. In debates preceding 
passage of the 1996 Telecommunications Act, two members of Congress 
expressed the view that Section 257 would cover conduct including 
that precluded by new Section 222(e), 47 U.S.C. Sec. 222(e), which 
prohibits local telephone service providers from charging 
discriminatory or unreasonable rates, or setting discriminatory or 
unreasonable terms or conditions, in selling subscriber lists to 
independent directory publishers. 142 Cong. Rec. H1145-06 at H1160

Paxon).
---------------------------------------------------------------------------

    6. Small businesses play a significant role in the U.S. economy. 
According to the U.S. Small Business Administration (SBA), in 1992 (the 
last year for which information is available), small businesses 
constituted the vast majority of all employers, employed 53% of the 
private work force, and provided 50% of all receipts. Research also has 
shown that small firms innovate at a per person rate twice that of 
large firms, spend more money on research and development (R&D), and 
more efficiently convert R&D efforts to new products than large 
firms.\11\ Furthermore, small businesses are able to serve narrower 
niche markets that may not be easily or profitably served by large 
corporations, especially as large telecommunications expand globally. 
Despite the role of small businesses in the economy, and the growth of 
the telecommunications market,\12\ small businesses currently 
constitute only a small portion of telecommunications companies.\13\

    \11\ ``Report of the FCC Small Business Advisory Committee to 
the Federal Communications Commission Regarding Gen Docket 90-314,'' 
reprinted at 8 FCC Rcd 7820, 7828 (1993) (SBAC PCS Report) (citing 
Joint Petition for Further Rulemaking of Advanced Mobilecomm 
Technologies, Inc. and Digital Spread Spectrum Technologies, Inc., 
in Gen Docket 90-314, Exhibit # 3, at 12-13).
    \12\ For example, according to Edge Media, worldwide revenues 
for Personal Communications Services (PCS) could grow to $31 billion 
for equipment and services by the year 2000, The Telecommunications 
Industry A Market Opportunity Analysis, Federal Communications 
Commission, Office of Communications Business Opportunities (June 
1995) (1995 OCBO Analysis) at 17 & n.30 (citing 1995 
Telecommunications Market Review and Forecast, North American 
Telecommunications Association), and PCS is expected to have 13.5 
million subscribers by the year 2000, id. at 1. The cellular market 
itself is growing rapidly: subscribership increased from 
approximately 5 million in 1990 to over 24 million in 1994. Id. The 
cable industry generated nearly $23 billion in 1994 and revenues 
will likely continue to climb, given that over 65% of all households 
with television sets subscribe to cable for video programming and 
over 95% of the country is wired for cable. Id. at 3.
    \13\ For example, the SBAC noted that SBA sales and employment 
data for the period 1989-1991 indicated that while the total number 
of small telecommunications enterprises had increased, cumulative 
market share possessed by those businesses decreased significantly. 
``Report of the FCC Small Business Advisory Committee to the Federal 
Communications Commission Regarding Gen Docket 90-314,'' reprinted 
at 8 FCC Rcd 7820, 7826 (1993) (SBAC PCS Report). Stated 
differently, bigger businesses were commanding larger portions of 
telecommunications revenues. Of a total of 990 firms in Standard 
Industrial Code 4812 (radiotelephone industries) in 1989, 971 firms 
with 249 employees or less possessed a 35.1% cumulative market share 
in 1991, compared to 927 firms in the same employment size range 
with a cumulative market share of 52.5% in 1989. Id. In contrast, 
there were a total of 19 firms with over 249 employees commanding a 
64.9% cumulative market share in 1991, compared to 21 firms of the 
same size range with a cumulative market share of 47.5% in 1989. 
Id.; see also FCC, ``Telecommunications Industry Revenue: TRS Fund 
Worksheet Data'' (February 1996) at Table 21 (of all 1,347 local 
exchange carriers (LEC) filing FCC Form 431 Telecommunications Relay 
Service (TRS) Fund Worksheets, the top fifth represent 98% of all 
LEC revenues; of all 97 interexchange carriers (IXC) filing TRS Fund 
Worksheets, the top fifth represent 99% of all IXC revenues);

Competitive Bidding, Fifth Report and Order, 9 FCC Rcd 5532, 5578, 
59 Fed. Reg. 37,566 (1994) (Competitive Bidding Fifth Report and 
Order) (comments of DCR Communications asserting that ten large 
companies--the six RBOCs, AirTouch (formerly owned by Pacific 
Telesis), McCaw (now owned by AT&T), GTE and Sprint--control nearly 
86 percent of the cellular industry, and that nine of these ten 
companies control 95% of the cellular population and licenses in the 
50 BTAs that have one million or more people).
---------------------------------------------------------------------------

III. Identifying Market Barriers

A. General Market Barriers

    7. In this section, we first request commenters to provide profile 
data about small telecommunications businesses, including financing 
sources and terms, services provided, markets served, geographic areas 
of operation, and employee workforce. This information will assist us 
in identifying market barriers and designing appropriate measures to 
eliminate barriers. Commenters may submit individualized or aggregated 
data. We request commenters to provide the following information in as 
much detail as possible regarding particular services, including but 
not limited to PCS, cellular, paging, SMR, satellite, radio, 
television, wired cable, wireless cable, local exchange, long-distance, 
access, on-line, messaging, and international services, and resale of 
any such service, as well as information regarding businesses that 
provide parts or services to providers of telecommunications services 
and information services:
    (1) Ownership structure, including identity of owner(s) by gender 
and racial group,14 as well as percentage of minority or female 
control;
---------------------------------------------------------------------------

    \14\ Consistent with the definition of ``minority'' in our 
rules, minority identification should be Black, Hispanic, American 
Indian, Alaskan Native, Asian, or Pacific Islander, as appropriate. 
See, e.g., 47 CFR Secs. 1.1621(b) and 24.720(i); see also Race and 
Ethnic Standards for Federal Statistics and Administration 
Reporting, OMB Statistical Policy Directive, No. 15 (1977).
---------------------------------------------------------------------------

    (2) Communications service(s) provided;
    (3) Geographic region(s) served;
    (4) Primary markets (e.g., businesses, residences, government);
    (5) Number of employees, job categories (i.e., officials and 
managers, professionals, technicians, clerical), and employee 
composition in job categories by race and gender.
    (6) Capital requirements for entry or expansion;
    (7) Funding sources and methods of raising capital;
    (8) Revenue, income and profit levels.
    8. To help fulfill our responsibilities under Sections 257 and 
309(j), we request comment on the following questions regarding market 
barriers.

[[Page 33068]]

Comments should be as specific as possible and identify with 
particularity the types of services and geographic regions covered.
    (1) What obstacles do small businesses face in accessing capital 
and credit?
    (2) Do small businesses obtain capital and credit under terms and 
conditions less favorable than those provided large businesses? If so, 
why?
    (3) What difficulties do small businesses face in their dealings 
with suppliers, vendors, contractors, or FCC licensees?
    (4) What obstacles do small businesses face in their abilities to 
resell, interconnect, or benefit from economies of scale?
    (5) Do high deposit requirements deter small business entry into 
resale?
    (6) Do small businesses have difficulty attracting or retaining 
clients?
    (7) Do small businesses have difficulty dealing with trade 
associations and other private entities?
    (8) Do small businesses have particular difficulties in obtaining 
government contracts, licenses, franchises, or other government 
benefits? Have small businesses faced any such problems regarding FCC 
policies or rules?
    (9) Do contracts for a single bidder to serve a large volume and 
diversity of companies through one contract disadvantage small 
businesses?
    (10) Do small businesses encounter difficulties attracting 
strategic partners?
    (11) In forming alliances with other entities, are small businesses 
required to do so under unfavorable terms and conditions for the small 
business?
    (12) Are there unique obstacles that small businesses face in 
entering or operating in the telecommunications field that are not 
faced by small businesses operating in other sectors (for example, in 
the retail or service sectors)?
    (13) Do small businesses experience difficulties identifying and 
obtaining access to spectrum?
    9. We request comment on how these impediments vary depending on 
the particular service provided. What particular types of businesses 
have difficulty getting started, operating, and expanding? Does the 
cost of capital differ for small broadcast stations versus small 
wireless providers? Does the cost of capital vary depending on the 
particular type of wireless (paging, SMR, PCS, etc.) or broadcast 
(television or radio) service offered? Do any other market entry 
barriers exist? For what services? Parties should comment on the 
geographic scope of any identified barrier, i.e., does the barrier 
exist nationwide, or in particular regions or locales? For any barrier, 
commenters also should identify whether it is a statutory 
requirement,15 government regulation, or external factor, e.g., 
difficulty obtaining loans.
---------------------------------------------------------------------------

    \15\ Section 257 requires that we report to Congress any 
statutory barriers that the Commission recommends be eliminated. 47 
U.S.C. 257(c).
---------------------------------------------------------------------------

    10. We also request comment on how these difficulties are 
influenced by size. Are impediments to entry and expansion greater for 
very small businesses? For example, does the cost of capital increase 
as the size of a small business decreases? Do very small businesses 
encounter greater difficulties in dealings with suppliers, vendors, or 
contractors than larger small businesses?

B. Unique Market Entry Barriers

    11. In this section, we seek information to help us identify any 
unique obstacles that small telecommunications businesses owned by 
women or minorities encounter in forming firms, providing service, or 
expanding in the telecommunications market. We explore this area 
because first, the legislative history of Section 257 suggests Congress 
was concerned about the underrepresentation of minority and women-owned 
small businesses in the telecommunications market and sought to 
increase competition by diversifying ownership. Second, Section 309(j) 
specifically requires that we further opportunities for businesses 
owned by women and minorities in the provision of spectrum-based 
services. Third, based on our licensing information and other 
statistical data, we know that a portion of small communications 
businesses are owned by women and minorities and there is evidence that 
these entities encounter unique market barriers.
    12. Evidence demonstrates that a principal barrier is minority or 
female status, rather than race or gender-neutral factors, and that 
this barrier contributes directly to low participation rates. For 
example, in the 1992 Small Business Act, Congress found that businesses 
owned by minorities or women have particular difficulties in obtaining 
capital.16 In the Women's Business Ownership Act of 1988,17 
Congress found that women as a group are subject to discrimination that 
adversely affects their ability to raise or secure capital. In 1993, 
the National Foundation for Women Business Owners found that women-
owned firms are 22% more likely to report difficulties with banks than 
are businesses at large, and that removal of financial barriers would 
encourage stronger growth among women-owned businesses, resulting in 
much greater growth throughout the economy.18 Further, in a 1992 
Report to the President and Congress, the National Women's Business 
Council cited lack of access to capital as the most pervasive barrier 
to success for women business owners.19

the 1992 Biennial Membership Survey of Women Business Owners,'' The 
National Foundation for Women Business Owners (October 1993).
    \19\ ``Annual Report to the President and Congress,'' National 
Women's Business Council (1992) at 11.
---------------------------------------------------------------------------

    13. As to communications businesses specifically, the American 
Women in Radio and Television, Inc. asserts that ``[b]ased on their 
gender, women today confront significant barriers in raising the amount 
of capital necessary to seize the ownership opportunity. This lack of 
access to capital has contributed directly to the low level of female 
ownership of mass media facilities.'' The Commission has recognized 
that ``considerable evidence has been presented showing that the 
primary impediment to minorities seeking to enter the communications 
industry or to increase their mass media holdings has been lack of 
access to capital.'' In April 1995, the National Telecommunications and 
Information Administration (NTIA) found that ``there are real barriers 
to minority participation in telecommunications, and that minorities 
often lack access to the types and amount of capital required to form 
and expand telecommunications businesses.'' Congressional testimony 
regarding minority discrimination in telecommunications shows that 
controlling for education, work experience, age, gender, and other 
factors, bank loan dollars, per dollar of owner equity investment, are 
160% higher for white firms ($1.85) than black firms ($1.16).20

Mass Media Ownership NPRM).
---------------------------------------------------------------------------

    14. The relatively low representation of women or minority-owned 
communications businesses also suggests that these types of businesses 
encounter unique obstacles in entering the telecommunications industry. 
According to the U.S. Census Bureau, in 1987 women owned and controlled 
1.9% (27) of 1,342 commercial television stations and 3.8% (394) of 
10,244 commercial radio stations in the

[[Page 33069]]

United States.21 In 1994, minorities owned and controlled 2.7% of 
the commercial television stations and 2.9% of the commercial radio 
stations in the United States.22 According to the Census Bureau, 
in 1992, Blacks owned 3.5% of the entities characterized generally as 
communications firms 23 and women owned 31%; and most of these 
businesses were solely-owned.24

Industrial Classification (SIC) Code), but rather by the general 
two-digit SIC Code for communications (#48). Consequently, since 
1987, the U.S. Census Bureau has not updated data on ownership of 
broadcast facilities by women, nor does the FCC collect such data. 
However, we sought comment on whether the Annual Ownership Report 
Form 323 should be amended to include information on the gender and 
race of broadcast license owners. Minority/Female Mass Media

    15. Finally, the participation level of minority or women-owned 
businesses in the Commission's spectrum auctions so far suggests that 
these entities may face unique obstacles. Because auctions will 
continue and various factors influence participation,25 we are not 
able to fully assess participation by women and minorities. Figures 
preliminarily indicate, however, that participation in auctions without 
bidding incentives for minorities and women is lower than participation 
in auctions with incentives. For example, in the broadband PCS auction 
for A and B blocks, which concluded in March 1995, no minority-owned 
businesses won a broadband PCS license and only one license (for one of 
the lower-priced markets) was won by a woman-owned business. In the MDS 
auction, which concluded on March 28, 1996, 7.7% of the eligible 
bidders claimed woman-owned status; 8.4% of the eligible bidders 
claimed minority-owned status. Of the 67 winners, 5.9% indicated they 
were women-owned; 7.5% indicated they were minority-owned.26 In 
the 900 MHz SMR auction, which concluded on April 15, 1996, 7.8% of the 
eligible bidders claimed woman-owned status and 3.9% claimed minority-
owned status. Of the 80 successful bidders, 6.3% indicated they were 
women-owned; 5% indicated they were minority-owned. Statistics for the 
PCS C block auction, which ended May 6, 1996, were higher, even though 
no competitive bidding incentives were available for businesses owned 
by minorities or women: 27 13.3% of the eligible bidders claimed 
woman-owned status, 18.0% claimed minority-owned status; 28 and of 
the 89 successful bidders, 16.9% indicated they were woman-owned; 28.1% 
indicated they were minority-owned.29
---------------------------------------------------------------------------

    \25\ Factors that may influence participation, include for 
example, the type of service, presence of incumbents, projected cost 
of a successful bid, capital requirements for offering service, 
access to capital, license coverage area, availability of Commission 
bidding incentives, and the extent of Commission outreach to small 
minority or women-owned businesses and new entrants.
    \26\ ``Multipoint Distribution Service Questions and Answers,'' 
FCC Auctions, Press Information (released March 29, 1996) at 3.
    \27\ In the Competitive Bidding Sixth Report and Order, the 
Commission noted that many minority-owned and women-owned applicants 
prepared to bid in the C Block auction in reliance on race and 
gender-based incentives. Thus, their rate of participation is likely 
higher than it would have been in the absence of any pre-auction 
incentives. See Amendment of Part 20 and 24 of the Commission's 
Rules--Broadband PCS Competitive Bidding and the Commercial Radio 
Service Spectrum Cap, Notice of Proposed Rulemaking, WT Docket No.

    16. By comparison, auctions that offered incentives for women and 
minority-owned businesses yielded higher participation by those 
entities (both as bidders and winners).
    For example, in the July 1994 IVDS auction, 22.5% of the registered 
bidders claimed status as minority-owned, and 33.2% as women-owned; of 
the auctioned licenses, 23.6% were awarded to bidders claiming 
minority-owned status, and 38.2% to bidders claiming women-owned 
status.30 In the nationwide narrowband PCS auction, also held in 
July 1994, of the 29 qualified bidders, 20.1% claimed minority-owned 
status and 10.3% claimed women-owned status.31 None of the winners 
were minority or women-owned businesses. In the Fall 1994 regional 
narrowband PCS auction, which offered a larger bidding credit than was 
available in the nationwide narrowband PCS auction, of the 28 qualified 
bidders, 35.7% claimed minority-owned status, and 28.6 % claimed women-
owned status.32 Of the nine winners, 22.2% claimed minority-owned 
status, and 33.3% claimed women-owned status.33

    17. We seek a broad and comprehensive record from which to 
determine whether the experiences of women and particular minority 
groups in entering and participating in the telecommunications market 
warrant adopting more significant gender or race-based incentives for 
minority or women-owned small businesses. Parties may submit personal 
accounts of individual experiences, studies, reports, statistical data, 
or any other relevant information.
    18. Commenters should address whether there are particular barriers 
to entry and expansion based on a small business owner's race or 
gender. If so, for which services? Do barriers differ by service, e.g., 
radio, television, advanced television, DBS, PCS, equipment 
manufacturing? What specific obstacles do women and minorities 
encounter in trying to start small communications businesses? Are there 
problems endemic to small women and minority-owned telecommunications 
businesses but not to small businesses owned by women and minorities in 
other industries (e.g., retail, real estate), and if so, why? Are any 
such difficulties the result of race/gender neutral factors such as 
economic status, geographic location, level of experience? Are 
differences in capital requirements determinative? What other factors 
play a role? Commenters should address to what extent any impediments 
are unique to small businesses owned by women or minorities, rather 
than small businesses generally.
    19. Discrimination can be a market entry barrier. Parties may 
submit evidence of past or current discrimination based on race or 
gender. Judicial findings of discrimination are

[[Page 33070]]

not required.34 Evidence of discrimination can be derived from a 
variety of sources, including academic research studies, adjudications, 
legislative findings, statistical data, and personal accounts. To the 
extent possible, evidence should relate to a particular racial, ethnic, 
or gender group.
---------------------------------------------------------------------------

    \34\ Parties should be mindful, however, that to the extent it 
is applicable to federal action, Croson requires that the government 
have a `` `strong basis in evidence for its conclusion that remedial 
action was necessary,' '' City of Richmond v. J.A.Croson, 488 U.S. 
469, 500 (1989) (quoting Wygant, 476 U.S. at 277); see also 
Memorandum Regarding Adarand to General Counsels from Walter 
Dellinger, Assistant Attorney General, Office of Legal Counsel, U.S. 
Department of Justice (dated June 28, 1995) (DOJ Memorandum) at 11.
---------------------------------------------------------------------------

    20. Women and minority owned businesses may have experienced 
discrimination or difficulty in obtaining government licenses. These 
experiences may have impeded the ability of such entities to enter the 
communications market, and consequently, impeded subsequent 
opportunities. We seek evidence of discrimination or unfavorable 
treatment by any governmental or public entity with respect to 
communications-related licenses, contracts or other benefits. It has 
been argued to the Commission that as a result of our system of 
awarding broadcast licenses in the 1940s and 1950s, no minority held a 
broadcast license until 1956 or won a comparative hearing until 1975 
35 and that special incentives for minority businesses ``are 
needed in order to compensate for a very long history of official 
actions which deprived minorities of meaningful access to the 
radiofrequency spectrum.'' 36 We solicit comment on this 
particular argument.

    21. Race or gender discrimination in employment may impede 
participation and advancement in the communications industry. 
Employment provides business knowledge, judgment, technical expertise, 
and entrepreneurial acumen, and other experience that is valuable in 
attaining ownership positions. For example, the Commission has found 
that employment in the broadcast industry is a valuable stepping stone 
to broadcast ownership.37

Order and NPRM (``increased employment opportunities are the 
foundation for increasing opportunities for minorities and women in 
all facets of the communications industry, including participation

---------------------------------------------------------------------------

    22. We seek any evidence that employment discrimination in the 
communications industry has been a barrier to entry in the 
telecommunications market by small businesses owned by minorities or 
women. Submissions should be detailed and should explain why the 
commenter believes the conduct at issue (e.g., failure to hire or 
promote) was based on race or gender discrimination, rather than the 
result of a race or gender-neutral factor (e.g., no job vacancy, job 
applicant not qualified for the position).

IV. Eliminating Market Barriers

A. Small Businesses Generally

    23. Section 257 requires that after identifying market barriers, we 
prescribe regulations to eliminate those barriers. In implementing this 
mandate, first, how should we define small businesses under Section 
257? By number of employees, gross revenue, net revenue, assets, or any 
other factor? Should we adopt a general size standard or specific 
standards for particular services (e.g., broadcast, PCS)? For example, 
the Commission's current Section 309(j) definitions are based on gross 
revenues and assets. Are there other factors the Commission should 
consider in defining what constitutes a small business? Should the 
Commission explore minimum capital requirements, debt/equity ratios, 
cash flow, net worth or other indicia of a business' ability to enter 
and compete in the marketplace? To formulate a policy using such 
indicia, the Commission would need specific financial information for 
small businesses generally, and requests that commenters recommending 
new approaches indicate the type of information needed by the 
Commission.
    24. Second, we seek comments and proposals regarding ways to 
eliminate market entry barriers and enhance opportunities for small 
businesses in communications services, including, e.g., wireline, 
wireless, mass media, cable, satellite. What types of incentives or 
requirements would be most effective in eliminating market entry 
barriers? Commenters may propose new initiatives or suggest changes to 
existing rules or make any other recommendation. Proposals may address, 
for example, sale of subscriber lists to independent directory 
publishers as recognized by Congress in enacting Section 257,38 or 
any other area. Commenters should provide data to support their 
proposals. Because Section 257 states that in prescribing rules to 
eliminate barriers we must rely on our rulemaking authority under 
provisions of the Act other than Section 257, we also request that 
commenters identify specific rulemaking provisions in the Act, e.g., 
Section 4(i) 39 that would support any such proposals.
---------------------------------------------------------------------------

    \38\ See supra note 10 (citing legislative history of Section 
257).
    \39\ 47 U.S.C. 154(i).
---------------------------------------------------------------------------

    25. Our Section 309(j) competitive bidding incentives for small 
businesses are examples of the types of mechanisms we could adopt in 
furtherance of our Section 257 mandate. Have bidding credits, 
installment payments, and reduced upfront payments enhanced 
opportunities for small business participation? Did the Commission's 
outreach efforts in providing information to prospective bidders 
enhance small business participation in each auction? If commenters 
believe the Commission's existing mechanisms could be modified to 
enhance opportunities for small businesses, please explain how, or 
suggest new approaches. In addition, we seek preliminary views on how 
the Section 309(j) incentives have operated in the five completed 
auctions employing small business incentives.40 For example, we 
are aware of concerns that due to the high level of bidding in the PCS 
C Block auction successful bidders may find it difficult later on to 
secure the necessary financial resources to build out their systems, 
and may ultimately encounter problems in the market against established 
competitors like incumbent cellular providers and the generally large, 
well-financed winners of PCS A and B block licenses.41 How do we 
balance the

[[Page 33071]]

desire to do more with the need to ensure that larger businesses do not 
usurp measures designed to aid small businesses? Do we need to do more 
to make sure that small businesses have meaningful opportunities to 
participate in the provision of spectrum-based services?

---------------------------------------------------------------------------

B. Minority or Women-Owned Small Businesses

    26. In Part III.B. above, we request data to identify whether small 
businesses owned by minorities or women experience unique market 
barriers. In this section, we explore whether there is sufficient 
evidence of market barriers to justify special incentives to eliminate 
those barriers. We do so because governmental action that takes race or 
gender into account is subject to particular constitutional standards: 
strict scrutiny for race-based incentives; intermediate scrutiny for 
gender-based incentives. We discuss these standards below and then seek 
comment on possible incentives that would satisfy the standards while 
at the same time furthering the mandate of Section 257.
1. Constitutional Standards
    27. The Constitution limits the power of government to classify 
individuals based on race or gender. Thus, federal incentive programs 
that take race or gender into account must satisfy constitutional 
standards. Courts reviewing government programs have applied different 
standards of review and reached various results depending on whether 
the classification covers race or gender and whether the classification 
burdens or benefits its subjects. Race-based programs must be narrowly 
tailored to further a compelling governmental interest. Gender-based 
programs must be substantially related to serve an important 
governmental interest.
    28. In Adarand Constructors, Inc. v. Pena, 42 the Supreme 
Court held that the federal government's use of race-based criteria for 
decisionmaking must satisfy the requirements of strict scrutiny.43 
The Court wrote:

    \42\ 115 S. Ct. 2097 (1995).
    \43\ Prior to Adarand, the standard differed for federal and 
state programs. Compare Fullilove v. Klutznick, 448 U.S. 448 (1980) 
(federal program evaluated under intermediate scrutiny) with City of 
Richmond v. J.A. Croson Co., 488 U.S. 469 (1989) (state program 
evaluated under strict scrutiny).
---------------------------------------------------------------------------

    [W]e hold today that all racial classifications, imposed by 
whatever federal, state, or local governmental actor, must be 
analyzed by a reviewing court under strict scrutiny. In other words, 
such classifications are constitutional only if they are narrowly 
tailored measures that further compelling governmental 
interests.44

    \44\ Id. at 2113.
---------------------------------------------------------------------------

    By this decision, the Court rejected its earlier legal analysis in 
Metro Broadcasting, Inc. v. FCC,45 which had applied the 
intermediate scrutiny standard of judicial review to the Commission's 
broadcasting distress sale and comparative preference policies for 
minorities.46
---------------------------------------------------------------------------

    \45\ 497 U.S. 547 (1990).
    \46\ In Metro Broadcasting, the Court held:
    [B]enign race-conscious measures mandated by Congress--even if 
those measures are not ``remedial'' in the sense of being designed 
to compensate victims of past governmental or societal 
discrimination--are constitutionally permissible to the extent that 
they serve important governmental objectives within the power of 
Congress and are substantially related to achievement of those 
objectives.
    Id. at 564-65.
---------------------------------------------------------------------------

    29. Overruling this aspect of Metro Broadcasting, the Court in 
Adarand clarified the permissible scope of affirmative action. First, 
the Court rejected the notion that the characterization of a racial 
classification as ``benign'' should entitle it a lower level of 
judicial review. Second, the Court applied to federal minority 
preference programs the strict scrutiny standard it had applied to a 
local contracting set-aside program in City of Richmond v. J.A. Croson 
Co.47 Yet in doing so, the Court emphasized its intention not to 
impinge upon the federal government's ability to actively combat both 
the practice and the continuing effects of discrimination. A majority 
of the Court rejected any notion that strict scrutiny review is 
``strict in theory, but fatal in fact.'' As Justice O'Connor stated in 
Adarand, ``[t]he unhappy persistence of both the practice and the 
lingering effects of racial discrimination against minority groups in 
this country is an unfortunate reality, and government is not 
disqualified from acting in response to it.'' 48 In rejecting the 
Metro Broadcasting standard, the Court nonetheless reasoned that 
because the Constitution protects individuals rather than groups, any 
governmental action based upon a racial group classification should be 
subject to ``detailed judicial inquiry.'' 49
---------------------------------------------------------------------------

    \47\ 488 U.S. 469 (1989).
    \48\ Adarand, 115 S. Ct. at 2117.
    \49\ Id. at 2113.
---------------------------------------------------------------------------

    30. Thus, Adarand established a new strict scrutiny standard for 
federal minority programs, based upon the two prong analysis of Croson: 
(1) the governmental interest underlying the affirmative action measure 
be ``compelling;'' and (2) the measure adopted must be ``narrowly 
tailored'' to serve that interest. Because a federal minority program 
has not yet been subjected to strict scrutiny pursuant to Adarand, 
judicial guidance regarding the strict scrutiny standard thus far is 
limited to Croson and lower court decisions applying strict scrutiny to 
state and local programs.50
---------------------------------------------------------------------------

    \50\ See Hopwood v. Texas, 78 F.3d 932 (5th Cir. 1996) petition 
for cert. filed (holding that the University of Texas School of Law 
may not use race as a factor in law school admissions).
---------------------------------------------------------------------------

    31. Under these cases, the most clearly permissible compelling 
governmental interest is remedying the effects of present or past 
discrimination. Thus, federal minority incentive programs that serve a 
remedial interest are likely to satisfy the compelling governmental 
interest prong. Discrimination can be that committed by the government 
itself, or by private actors within the government's jurisdiction (such 
that the government was a ``passive participant'' or facilitated the 
perpetuation of a system of exclusion). The government must identify 
with some precision the discrimination to be redressed,51 
including evidence of discrimination against particular minority 
groups.52 General, historical discrimination is an insufficient 
predicate. ``[A]n amorphous claim that there has been past 
discrimination in a particular industry cannot justify the use of an 
unyielding racial quota.'' 53 In addition, the government should 
have a ``strong basis,'' approaching a ``prima facie case of 
constitutional or statutory violation'' 54 of the rights of 
minorities. Croson permits remedial relief on the basis of ``evidence 
of a pattern of individual discriminatory acts * * * supported by 
appropriate statistical proof.'' 55 Post-Croson cases have held 
that statistical evidence can be probative of discrimination in the 
remedial setting,56 and that anecdotal evidence can buttress 
statistical evidence.57
---------------------------------------------------------------------------

    \51\ Croson requires that a government ``identif[y] 
discrimination with the particularity required by the Fourteenth 
Amendment.'' Croson, 488 U.S at 492, 499, 509; see also DOJ 
Memorandum at 22.
    \52\ Croson 488 U.S. at 506 (``The random inclusion of racial 
groups that, as a practical matter, may never have suffered from 
discrimination in the construction industry in Richmond suggests 
that perhaps the city's purpose was not in fact to remedy past 
discrimination.'')
    \53\ Id. at 499.
    \54\ Id. at 500.
    \55\ Id. at 509.
    \56\ See, e.g., Peightal v. Metropolitan Dade County, 26 F.3d 
1548, 1556 (11th Cir. 1994) (statistical evidence constitutes 
``requisite `strong basis in evidence' mandated by Croson'').
    \57\ See, e.g., Coral Construction Co., 941 F.2d at 919 
(convincing anecdotal and statistical evidence can be ``potent''); 
see also DOJ Memorandum at 12-13.

---------------------------------------------------------------------------

[[Page 33072]]

    32. Courts generally give more deference to Congressional race-
based remedial action than to state action because of Congress' special 
remedial powers under the Fourteenth Amendment. Thus, it is possible 
that the Croson standards for remedial action, e.g., the degree of 
discrimination required to justify remedial action,58 might be 
lower where Congressional findings are involved.59
---------------------------------------------------------------------------

    \58\ Croson, however, involved a race preference program adopted 
at the local, rather than federal, level. See Croson, 488 U.S. at 
469.
    \59\ In the DOJ Memorandum, Justice states that Adarand 
``hinted'' that where a federal preference program is 
congressionally mandated, the Croson standards may apply more 
loosely. DOJ Memorandum at 30. The Adarand majority confronted the 
issue of congressional versus state remedial power, noting that 
various Members of the Court have taken different views of the 
authority that Section 5 of the Fourteenth Amendment confers upon 
Congress--power not delegated to the states--and the extent to which 
courts should defer to congressional exercise of that authority. 
Adarand, 115 S. Ct. at 2114. The Court concluded it did not need to 
resolve those differences in Adarand, and rejecting Justice Stevens' 
assertion to the contrary, stated that none of the Justices in 
Adarand repudiated previously expressed views on this subject. 
Croson suggested that Congress has broader authority than the 
states--a positive grant of legislative power--and rejected the City 
of Richmond's finding that it was remedying the present effects of 
past discrimination. Croson, 488 U.S. at 498.
---------------------------------------------------------------------------

    33. A government may adopt race or gender based programs for 
reasons other than to remedy discrimination. Such objectives are 
nonremedial. For example, in Regents of the University of California v. 
Bakke,60 the purpose of the state of California's college 
admissions program was to diversify the student body. No majority 
opinion of the Court has addressed the sufficiency of nonremedial 
objectives. Because Croson addressed the authority of a local 
government to engage in remedial action, it did not decide the 
sufficiency of nonremedial objectives as a compelling interest. In 
Croson, Justice O'Connor stated that affirmative action must be 
``strictly reserved for the remedial setting.'' 61 In Justice 
Stevens' dissent in Adarand, however, he stated that Adarand does not 
expressly adopt the view that past discrimination is the only valid 
compelling governmental interest; nor does it prohibit nonremedial 
objectives.62 In Bakke, Justice Powell found that a university has 
a compelling interest in taking the race of applicants into account in 
its admission process in order to foster greater diversity among the 
student body to enhance the exchange of ideas on campus,63 and in 
Wygant v. Jackson Board of Education,64 Justice O'Connor expressed 
approval of that view.65

that the University of Texas ``law school has presented no 
compelling justification, under the Fourteenth Amendment or Supreme 
Court precedent, that allows it to continue to elevate some races 
over others, even for the wholesome purpose of correcting perceived 
racial imbalance in the student body.'' Hopwood, 78 F.3d at 934. A 
majority of the Hopwood panel specifically rejected Justice Powell's 
opinion in Bakke that diversity can be a compelling interest as 
``not binding precedent'' and concluded that ``any consideration of 
race or ethnicity by the law school for the purpose of achieving a 
diverse student body is not a compelling interest under the 
Fourteenth Amendment.'' Id. at 944. In a concurring opinion, Judge 
Wiener disagreed with the panel's opinion that diversity can never 
be a compelling governmental interest, but concluded that the 
program in question was not narrowly tailored because it singled out 
only two minority groups--Blacks and Mexican Americans. Id. at 962-
68.

    34. The second prong of strict scrutiny analysis requires that the 
use of any racial classification be ``narrowly tailored,'' to ensure 
that ``the means chosen `fit' [the] compelling goal so closely that 
there is little or no possibility that the motive for the 
classification was illegitimate racial prejudice or stereotype.'' 
66 In Adarand, the Court identified two factors in determining 
whether the use of a racial classification is narrowly-tailored: (1) 
Whether race-neutral alternatives were considered, and (2) whether the 
measure is appropriately limited in duration so that it will not 
continue longer than purposes for which it was adopted. Additional 
factors, identified in post-Croson cases, are: (3) the flexibility of 
the program, e.g., whether it contains a waiver provision that may 
narrow its scope; (4) the manner in which race is used, whether as a 
determinant, or as one of several factors; (5) whether any numerical 
target is compared to the relevant number of qualified minorities or to 
the population of minorities as a whole; (6) the extent of the burden 
on nonminorities.
---------------------------------------------------------------------------

    \66\ Croson, 488 U.S. at 493.
---------------------------------------------------------------------------

    35. Since Adarand, the Supreme Court has not ruled on the standard 
of review for federal gender-based programs, although the issue is 
before it in a pending case.67 Prior to Adarand, the Court applied 
intermediate scrutiny; that standard currently applies.68 Under 
the intermediate scrutiny standard, ``[t]o withstand constitutional 
challenge * * * classifications by gender must serve important 
governmental objectives and must be substantially related to those 
objectives.'' 69
---------------------------------------------------------------------------

    \67\ United States v. Commonwealth of Virginia, 44 F.3d 1229 
(1995), cert. granted 116 S. Ct. 281 (1995) (No. 94-1941) (argued 
Jan. 17, 1996). The case presents the question whether the Equal 
Protection Clause permits a state to maintain single-sex military-
style educational programs.
    \68\ Craig v. Boren, 429 U.S. 190, 197 (1976). Thus far, the 
Court has not decided whether gender is a suspect category. See, 
e.g., J.E.B. v. Alabama ex rel. T.B., 114 S. Ct. at 1419, 1425 n.6 
(1992) (concluding that gender-based peremptory challenges are not 
substantially related to an important governmental objective and 
finding ``once again'' that the Court need not decide whether gender 
classifications are inherently suspect''); Mississippi University 
for Women v. Hogan, 458 U.S. 718, 724 n.9 (1982) (finding it 
``unnecessary'' to decide whether classifications based upon gender 
are inherently suspect).
    \69\ Boren, 429 U.S. at 197; see also J.E.B. v. Alabama ex rel. 
T.B., 114 S. Ct. 1419, 1425 (1994) (``our Nation has had a long and 
unfortunate history of sex discrimination, a history which warrants 
the heightened scrutiny we afford all gender-based classifications 
today''); City of Cleburne v. Cleburne Living Center, 473 U.S. 432, 
440 (1985) (``[l]egislative classifications based on gender * * * 
call for a heightened standard of review'').
---------------------------------------------------------------------------

    36. In applying intermediate scrutiny to invidious gender-based 
classifications, the Court has expressed concern that such 
classifications are, in fact ``reflective of `archaic and overbroad' 
generalizations about gender'' or are ``based on `outdated 
misconceptions concerning the role of females in the home rather than 
in the marketplace and world of ideas.' '' 70
---------------------------------------------------------------------------

    \70\ J.E.B., 114 S. Ct. at 1424-25 (citations omitted). The 
Court has rejected attempts to exclude or protect one gender based 
on presumptions. See Hogan, 458 U.S. at 725.
---------------------------------------------------------------------------

    37. It is unclear what standard would apply to benign gender 
classifications. In Adarand, the Court refused to apply a less strict 
standard to benign race-based classifications than the standard applied 
to ``invidious'' race-based classifications. Although Adarand did not 
address gender, its rejection of a lower standard for benign action in 
the race context suggests that the same standard applied to invidious 
gender classifications should apply to benign gender classifications. 
This conclusion is supported by the Court's analysis in Mississippi 
University for Woman v. Hogan,71 which held that a state 
university's exclusion of men from its nursing program violated the 
Equal Protection Clause under a test of intermediate scrutiny.
---------------------------------------------------------------------------

    \71\ 458 U.S. 718 (1982).
---------------------------------------------------------------------------

    38. In evaluating the second prong of the intermediate scrutiny 
test--whether a gender classification is substantially related to the 
government's objective--courts consider several factors, including the 
correlation between gender and the actual activity the government seeks 
to regulate and the practical effect of the program.72
---------------------------------------------------------------------------

    \72\ See, e.g., Boren, 429 U.S. at 200-04 (finding that the low 
disparity between drunk driving statistics for men and women 
``exemplifies the ultimate unpersuasiveness of this evidentiary 
record''); Hogan, 458 U.S. at 730-32 (finding that presence of men 
in nursing school would not have negative effect on women students, 
and that the record is ``flatly inconsistent'' with the claim that 
excluding men is necessary to reach the state's educational goals 
and falls ``far short'' of the ``'exceedingly persuasive 
justification''' needed to sustain a gender-based classification).

---------------------------------------------------------------------------

2. Possible Incentives
    39. As described above, a record of discrimination against a 
particular group is necessary to support remedial measures to remedy 
such discrimination. We seek comment on whether under the compelling 
governmental interest prong, there is sufficient evidence of 
discrimination in the communications industry against any particular 
minority group to support race-based incentives to eliminate market 
entry barriers for such group. As discussed above, minority groups 
include African Americans, Hispanics, American Indians, Alaskan 
Natives, Asians, and Pacific Islanders.73 We also ask whether 
there is sufficient evidence of discrimination against women in 
telecommunications to justify remedial-based mechanisms to eliminate 
market entry barriers for women, under either the compelling 
governmental interest prong (strict scrutiny) or important governmental 
interest (intermediate scrutiny). Parties may use any data submitted in 
response to Part III above to support their comments.
---------------------------------------------------------------------------

    \73\ See supra n.14 (definition of minority). When considering 
incentives for Native Americans, the Commission looks for guidance 
to the Indian Commerce clause, which recognizes the status of tribes 
as sovereign nations. See Competitive Bidding Sixth Report and 
Order, 11 FCC Rcd at 155-56. See also DOJ Memorandum at 8 (``Adarand 
does not require strict scrutiny review for programs benefiting 
Native Americans as members of federally recognized Indian 
tribes'').
---------------------------------------------------------------------------

    40. We also seek comment on any nonremedial objectives that would 
justify the use of race and gender-based incentives and also serve the 
Section 257 mandate of decreasing market entry barriers for small 
telecommunications firms owned by minorities and women. Nonremedial 
objectives could be in addition to the objective of remedying past 
discrimination; thus, they may provide a separate basis for 
governmental action that takes race and gender into account. For 
example, the Commission has sought to fulfill the nonremedial objective 
of increasing diversity of voices and viewpoints over the airwaves 
through various minority and women-based programs.74 Those 
programs also decrease market entry barriers by providing new 
opportunities for women and minorities and by increasing incentives for 
other firms to do business with those entities. Other nonremedial 
objectives that could justify taking race or gender into account in 
Commission programs and also help eliminate market entry barriers might 
include favoring diversity of media voices as required by Section 
257(b),75 promoting economic opportunity and competition as 
encouraged in the legislative history of Section 257 76 and 
Section 257(b),77 and as required by Section 309(j),78 or 
promoting the public interest.79 We seek comment on these 
nonremedial objectives 80 and request commenters to suggest other 
nonremedial objectives that would satisfy the governmental interest 
prong under strict (race) or intermediate (gender) scrutiny.
---------------------------------------------------------------------------

    \74\ See, e.g., the broadcast licensing policy which was adopted 
following the D.C. Circuit decision in TV 9, Inc. v. FCC, 495 F.2d 
929 (D.C. Cir. 1973), cert. denied, 419 U.S. 986 (1974). The 
Commission considered a minority applicant's proposed participation 
in station operation as one of several factors in comparing 
applicants for mutually exclusive broadcast licenses. In Metro 
Broadcasting, Inc. v. FCC, 497 U.S. 547, 567 (1990), the Supreme 
Court upheld our licensing policy, however, in Lamprecht v. FCC, 958 
F.2d 395, 398 (D.C. Cir. 1992), the D.C. Circuit found the policy 
for women to be unconstitutional. Thereafter, in Bechtel v. FCC, 10 
F.3d 875, 877, 887 (D.C. Cir. 1993), the D.C. Circuit held that the 
integration credit, upon which the minority/female licensing policy 
is based, was arbitrary and capricious. Following Bechtel, the 
Commission suspended comparative hearings altogether.
    \75\ 47 U.S.C. 257(b).
    \76\ See supra para. 3 and n.8.
    \77\ Section 257(b) provides: ``In carrying out subsection (a), 
the Commission shall seek to promote the policies and purposes of 
this Act favoring * * * vigorous economic competition.'' 47 U.S.C. 
Sec. 257(b).
    \78\ 47 U.S.C. 309(j).
    \79\ See, e.g., 47 U.S.C. 201 (public interest regulation of 
common carriers); 47 U.S.C. 257(b) (promotion of public interest, 
convenience and necessity in carrying out Section 257(a)); 47 U.S.C. 
303 (public interest regulation of radio services).
    \80\ Depending on the record of discrimination developed, any 
such nonremedial objectives could be remedial in nature. For 
example, if there were a strong record of discrimination against 
women-owned small businesses in the telecommunications market (which 
itself would be an entry barrier), we could adopt a mechanism 
intended to increase ownership opportunities for those businesses. 
The immediate objective--increasing ownership--would be a means of 
achieving the ultimate objective--remedying discrimination.
---------------------------------------------------------------------------

    41. We also request that parties propose incentives to meet these 
remedial or nonremedial objectives. Commenters may address incentives 
that the Commission has adopted in the past that eliminated or reduced 
barriers to market entry, e.g., designated entity rules for Section 
309(j) services, as well as propose new incentives. We also seek 
comment on whether incentives that foster ownership or employment of 
women or minorities in telecommunications would further these 
objectives.81 Parties should explain what objective an incentive 
would be intended to achieve and whether it is properly designed to 
achieve that objective, i.e., narrowly tailored (strict scrutiny); 
substantially related (intermediate scrutiny). Parties may support 
their proposals with data and should identify specific provisions of 
the Act that would authorize us to implement those proposals.
---------------------------------------------------------------------------

    \81\ The legislative history of Section 257 indicates that 
Congress recognized a nexus between ownership and competition: 
``[M]inority and women-owned small businesses continue to be 
extremely under represented in the telecommunications field * * *. 
Underlying this amendment [Section 257] is the obvious fact that 
diversity of ownership remains a key to the competitiveness of the 
U.S. telecommunications marketplace.'' 142 Cong. Rec. H1141 at 
H1177-78 (daily ed. Feb. 1, 1996) (statement of Rep. Collins).
    We note that communications is among a handful of industries 
with the highest expected growth between the year 1990 and 2005, and 
is predicted to provide women opportunities for advancement into 
management and decisionmaking positions. A Solid Investment: Making 
Full Use of the Nation's Human Capital, Recommendations of the 
Federal Glass Ceiling Commission (November 1995) (Glass Ceiling 
Report), Special Supplement at S-9. In addition, facilitating 
employment could serve the public interest by enhancing 
productivity: the Glass Ceiling Commission found that 
``[o]rganizations that excel at leveraging diversity (including 
hiring and promoting minorities and women into senior positions) can 
experience better financial performance in the long run than those 
which are not effective in managing diversity.'' Glass Ceiling 
Report, Special Supplement at S-8.
---------------------------------------------------------------------------

C. Furthering Section 257(b) Objectives

    42. As described in the Introduction to this NOI, in Section 
257(b), Congress required that in implementing our market barriers 
initiatives, the Commission must ``promote the policies and purposes of 
this Act favoring diversity of media voices, vigorous economic 
competition, technological advancement, and promotion of the public 
interest, convenience, and necessity.'' 82 We ask for comment on 
how the Commission should foster these objectives in its efforts to 
eliminate market barriers for entrepreneurs and small businesses.
---------------------------------------------------------------------------

    \82\ 47 U.S.C. 257(b).
---------------------------------------------------------------------------

V. Administrative Matters

    43. Reason for Action: Section 101 of the Telecommunications Act of 
1996 (1996 Telecommunications Act),83 adds new Section 257 to the 
Communications Act of 1934.84 Section 257 requires the Commission, 
within 15 months after enactment, to complete a proceeding ``for the 
purpose of identifying and eliminating, by regulations pursuant to its 
authority under this Act * * * market entry barriers for entrepreneurs 
and other small businesses in the provision and ownership of 
telecommunications services and

[[Page 33074]]

information services, or in the provision of parts or services to 
providers of telecommunications services and information services.'' In 
implementing Section 257, the Commission must ``promote the policies 
and purposes of this Act favoring diversity of media voices, vigorous 
economic competition, technological advancement, and promotion of the 
public interest, convenience and necessity.'' Every three years 
following the completion of the market barriers proceeding, the 
Commission must report to Congress on regulations that have been issued 
to eliminate barriers and any statutory barriers that the Commission 
recommends be eliminated. This Notice of Inquiry commences our omnibus 
Section 257 proceeding.
---------------------------------------------------------------------------

    \83\ Telecommunications Act of 1996, Public Law No. 104-104, 110 
Stat. 56 (1996).
    \84\ 47 U.S.C. 151 et seq.
---------------------------------------------------------------------------

    44. Objectives: The Commission seeks to develop a full record of 
profile data on the type and scope of market entry barriers in the 
telecommunications industry faced by small businesses. To this end, the 
Commission solicits specific information regarding financing sources 
and terms, services provided, markets served, geographic areas of 
operation, and employee workforce. The Commission also seeks 
information concerning obstacles small telecommunications businesses 
encounter, as well as any unique obstacles that such businesses owned 
by women and minorities encounter. We also will undertake specific 
initiatives that further the objective of Section 257 to eliminate 
market entry barriers for small businesses. The record developed in 
connection with these initiatives also will assist us in achieving our 
mandate under Section 309(j) of the Communications Act to disseminate 
licenses for auctionable spectrum-based services to small businesses, 
rural telephone companies, and businesses owned by women and 
minorities, as well as in fulfilling our general obligation to serve 
the public interest.
    45. Legal Basis: The proposed action is authorized under the 
Communications Act of 1934, 47 U.S.C. 257.
    46. Reporting, Recordkeeping, and Other Compliance Requirements: 
None
    47. Description, Potential Impact and Number of Small Entities 
Effected: None
    48. Federal Rules Which Overlap, Duplicate or Conflict With These 
Rules: None
    49. Significant Alternatives Minimizing Impact on Small Entities 
and Consistent with Stated Objectives: This NOI solicits comment on a 
variety of issues and recommendations that impact small businesses. Any 
additional significant issues or recommendations related to small 
businesses in the telecommunications industry presented in the comments 
also will be considered.
    50. Paperwork Reduction Act: The requirements proposed herein have 
been analyzed with respect to the Paperwork Reduction Act of 1995 and 
found to impose no new or modified information collection requirements.

49 CFR Part 7

[Docket No. OST-96-1430; Notice 96-17]
RIN 2105-AC58

Public Availability of Information

AGENCY: Office of the Secretary, DOT.

ACTION: Notice of proposed rulemaking.

-----------------------------------------------------------------------

SUMMARY: Department of Transportation proposes to revise regulations 
implementing the Freedom of Information Act (FOIA), 5 U.S.C. 552. This 
revision updates organizational changes since the last revision and 
streamlines the regulations in order to make the regulations more 
useful.

DATES: Comments are due August 26, 1996.

ADDRESSES: Comments should be addressed to Documentary Services 
Division, Attention: Docket Section, Room PL401, Docket No. OST-96-
1430, Department of Transportation, C-55, Washington, DC 20590. Any 
person wishing acknowledgment that his/her comments have been received 
should include a self-addressed stamped postcard. Comments received 
will be available for public inspection and copying in the Documentary 
Services Division, Room PL401, Department of Transportation Building, 
400 Seventh Street, SW, Washington, DC, from 10:00 AM to 5:00 PM ET 
Monday through Friday except Federal holidays.

FOR FURTHER INFORMATION CONTACT: Dorothy A. Chambers, Chief, FOIA 
Division, Office of the General Counsel, C-12, Department of 
Transportation, Washington, DC 20590, telephone (202) 366-4542, FAX 
(202) 366-7152.

SUPPLEMENTARY INFORMATION: The President instituted a Regulatory Review 
initiative, for the reinvention of regulations by eliminating 
duplicate, redundant, or unnecessary language and revising regulations 
to meet the needs of users. In response to this initiative, we have 
reviewed part 7 and are proposing to revise this section to update and 
streamline information on public availability of information. We 
propose to reorganize this part by combining in subpart B sections that 
relate to information that is publicly available without a specific 
request. Similarly, we have combined sections in subpart C that address 
information that must be requested under FOIA. We have shortened the 
descriptions of FOIA exemptions and propose to delete the Appendices 
that set forth redundant information concerning document inspection 
facilities. We propose to replace these appendices with provisions in 
Secs. 7.10 and 7.15, which set forth necessary information regarding 
public records available at Department Docket locations and FOIA 
contacts for records requested under the FOIA.

Analysis of Regulatory Impacts

    This amendment is not a ``significant regulatory action'' within 
the meaning of Executive Order 12866. It is also not significant within 
the definition in DOT's Regulatory Policies and Procedures, 49 FR 11034 
(1979), in part because it does not involve any change in important 
Departmental policies. Because the economic impact should be minimal, 
further regulatory evaluation is not necessary. Moreover, I certify 
that this proposal will not have a significant economic impact on a 
substantial number of small entities.
    This proposal does not significantly affect the environment, and 
therefore an environmental impact statement is not required under the 
National Environmental Policy Act of 1969. It has also been reviewed 
under Executive Order 12612, Federalism, and it has been determined 
that it does not have sufficient implications for federalism to warrant 
preparation of a Federalism Assessment.
    Finally, the proposal does not contain any collection of 
information requirements, requiring review under the Paperwork 
Reduction Act, as amended.

any manner be required to resort to, or be adversely affected by, any 
procedure or matter required to be published in the Federal Register, 
but not so published.

Sec. 7.5   Availability of Opinions, Orders, Staff Manuals, Statements 
of Policy, and Interpretations and Indices.

    (a) This section implements 5 U.S.C. 552(a)(2). It prescribes the 
rules governing the availability for public inspection and copying of 
the following:
    (1) Any final opinion (including a concurring or dissenting 
opinion) or order made in the adjudication of a case.
    (2) Any policy or interpretation that has been adopted under the 
authority of the Department, including any policy or interpretation 
concerning a particular factual situation, if that policy or 
interpretation can reasonably be expected to have precedential value in 
any case involving a member of the public in a similar situation.
    (3) Any administrative staff manual or instruction to staff that 
affects any member of the public, including the prescribing of any 
standard, procedure, or policy that, when implemented, requires or 
limits any action of any member of the public or prescribes the manner 
of performance of any activity by any member of the public. However, 
this does not include staff manuals or instructions to staff concerning 
internal operating rules, practices, guidelines, and procedures for 
Departmental inspectors, investigators, law enforcement officers, 
examiners, auditors, and negotiators and other information developed 
predominantly for internal use, the release of which

[[Page 33077]]

could significantly risk circumvention of agency regulations or 
statutes.
    (b) Any material listed in paragraph (a) of this section that is 
not made available for public inspection and copying, or that is not 
indexed as required by Sec. 7.7, may not be cited, relied on, or used 
as precedent by the Department to affect any member of the public 
adversely unless the person to whose detriment it is relied on, used, 
or cited has had actual timely notice of the material.
    (c) This section does not apply to material that is published in 
the Federal Register or covered by subpart C of this part.

Sec. 7.6   Deletion of Identifying Detail.

    Whenever it is determined to be necessary to prevent a clearly 
unwarranted invasion of personal privacy, identifying details will be 
deleted from any record covered by this subpart that is published or 
made available for inspection. A full explanation of the justification 
for the deletion will accompany the record published or made available 
for inspection.

Sec. 7.7   Access to Materials and Indices.

    (a) Except as provided in paragraph (b) of this section, material 
listed in Sec. 7.5 will be made available for inspection and copying to 
any member of the public at document inspection facilities of the 
Department. It has been determined that it is unnecessary and 
impracticable to publish the index of materials in the Federal 
Register. Information as to the kinds of materials available at each 
facility may be obtained from the facility or the headquarters of the 
operating element of which it is a part.
    (b) The material listed in Sec. 7.5 that is published and offered 
for sale will be indexed, but is not required to be kept available for 
public inspection. Whenever practicable, however, it will be made 
available for public inspection at any document inspection facility 
maintained by the Office of the Secretary or an operating element, as 
appropriate.

Sec. 7.8   Copies.

    Copies of any material covered by this subpart that is not 
published and offered for sale may be ordered, upon payment of the 
appropriate fee, from the Docket Offices listed in Sec. 7.10. Copies 
will be certified upon request and payment of the fee prescribed in 
Sec. 7.43.

Sec. 7.9   Protection of Records.

    (a) Records made available for inspection and copying may not be 
removed, altered, destroyed, or mutilated.
    (b) 18 U.S.C. 641 provides, in pertinent part, for criminal 
penalties for embezzlement or theft of government records.
    (c) 18 U.S.C. 2071 provides, in pertinent part, for criminal 
penalties for the willful and unlawful concealment, mutilation or 
destruction of, or the attempt to conceal, mutilate, or destroy, 
government records.

Subpart C--Availability of Reasonably Described Records Under the 
Freedom of Information Act

Sec. 7.11   Applicability.

    (a) This subpart implements 5 U.S.C 552(a)(3), and prescribes the 
regulations governing public inspection and copying of reasonably 
described records under the Freedom of Information Act.
    (b) This subpart does not apply to:
    (1) Records published in the Federal Register, opinions in the 
adjudication of cases, statements of policy and interpretations, and 
administrative staff manuals that have been published or made available 
under subpart B of this part.
    (2) Records or information compiled for law enforcement purposes 
and covered by the disclosure exemption described in Sec. 7.13(c)(7) 
if--
    (i) The investigation or proceeding involves a possible violation 
of criminal law; and
    (ii) There is reason to believe that--
    (A) The subject of the investigation or proceeding is not aware of 
its pendency, and
    (B) Disclosure of the existence of the records could reasonably be 
expected to interfere with enforcement proceedings.
    (3) Informant records maintained by a criminal law enforcement 
component of the Department under an informant's name or personal

name or personal identifier, unless the informant's status as an 
informant has been officially confirmed.

Sec. 7.12   Administration of Part.

    Authority to administer this part and to issue determinations with 
respect to initial requests is delegated as follows:
    (a) to the General Counsel for the records of the Office of the 
Secretary other than the Office of the Inspector General.
    (b) to the Inspector General for records of the Office of the 
Inspector General.
    (c) to the Administrator of each operating element, who may 
redelegate to officers of that element the authority to administer this 
part in connection with defined groups of records. However, each 
Administrator may redelegate the duties under subpart D of this part to 
consider appeals of initial denials of requests for records only to his 
or her deputy or to not more than one other officer who reports 
directly to the Administrator and who is located at the headquarters of 
that operating element.

Sec. 7.13   Records Available.

    (a) Policy. It is the policy of the Department of Transportation to 
make

[[Page 33078]]

the records of the Department available to the public to the greatest 
extent possible, in keeping with the spirit of the Freedom of 
Information Act. This includes providing reasonably segregable 
information from documents that contain information that may be 
withheld.
    (b) Statutory disclosure requirement. The Act requires that the 
Department, on a request from a member of the public submitted in 
accordance with the procedures in this subpart, make requested records 
available for inspection and copying.
    (c) Statutory exemptions. Exempted from the Act's statutory 
disclosure requirement are matters that are:

Executive Order to be kept secret in the interest of national defense 
or foreign policy, and
    (ii) In fact properly classified pursuant to such Executive order;
    (2) Related solely to the internal personnel rules and practices of 
an agency;
    (3) Specifically exempted from mandatory disclosure by statute 
(other than the Privacy Act), provided that such statute--
    (i) Requires that the matters be withheld from the public in such a 
manner as to leave not any discretion on the issue, or

particular criteria for withholding or refers to particular types of 
matters to be withheld;
    (4) Trade secrets and commercial or financial information obtained

not be available by law to a party other than an agency in litigation 
with the agency;
    (6) Personnel and medical files and similar files the disclosure of 
which would constitute a clearly unwarranted invasion of personal 
privacy;
    (7) Records or information compiled for law enforcement purposes, 
but only to the extent that the production of such law enforcement 
records or information--
    (i) Could reasonably be expected to interfere with enforcement 
proceedings,
    (ii) Would deprive a person of a right to a fair or an impartial 
adjudication,
    (iii) Could reasonably be expected to constitute an unwarranted 
invasion of personal privacy,
    (vi) Could reasonably be expected to disclose the identity of a 
confidential source, including a State, local, or foreign agency or 
authority or any private institution that furnished information on a 
confidential basis, and, in the case of a record or information 
compiled by a criminal law enforcement authority in the course of a 
criminal investigation, or by an agency conducting a lawful national 
security intelligence investigation, information furnished by a 
confidential source,
    (v) Would disclose techniques and procedures for law enforcement 
investigations or prosecutions or would disclose guidelines for law 
enforcement investigations or prosecutions if such disclosure could 
reasonably be expected to risk circumvention of the law, or
    (vi) Could reasonably be expected to endanger the life or physical 
safety of any individual;
    (8) Contained in or related to examination, operating, or condition 
reports prepared by, on behalf of, or for the use of an agency 
responsible for the regulation or supervision of financial 
institutions; or

maps, concerning wells.

Sec. 7.14   Requests for Records.

    (a) Each person desiring access to or a copy of a record covered by 
this subpart shall comply with the following provisions:
    (1) A written request must be made for the record.
    (2) Such request should indicate that it is being made under the 
Freedom of Information Act.
    (3) The envelope in which the request is sent should be prominently 
marked: ``FOIA.''
    (4) The request should be addressed to the appropriate office as 
set forth in Sec. 7.15.
    (b) If the requirements of paragraph (a) of this section are not 
met, treatment of the request will be at the discretion of the agency. 
The ten-day limit for responding to requests, described in Sec. 7.31, 
will not start to run until the request has been identified, or would 
have been identified with the exercise of due diligence, by an employee 
of the Department as a request pursuant to the Freedom of Information 
Act and has been received by the office to which it should have been 
originally sent.
    (c) Form of Requests. (1) Each request should describe the 
particular record to the fullest extent possible. The request should 
describe the subject matter of the record, and, if known, indicate the 
date when it was made, the place where it was made, and the person or 
office that made it. If the description does not enable the office 
handling the request to identify or locate the record sought, that 
office will notify the person making the request and, to the extent 
possible, indicate the additional data required.
    (2) Each request shall--
    (i) Specify the fee category (commercial use, news media, 
educational institution, noncommercial scientific institution, or 
other) in which the requester claims the request to fall and the basis 
of this claim (see subpart F for fees and fee waiver requirements), and
    (ii) State the maximum amount of fees that the requester is willing 
to pay or include a request for a fee waiver.
    (iii) Requesters are advised that the time for responding to 
requests set forth in subpart E may be delayed--
    (A) If a requester has not sufficiently identified the fee category 
applicable to the request,
    (B) If a requester has not stated a willingness to pay fees as high 
as anticipated by the Department, or
    (C) If a fee waiver request is denied and the requester has not 
included an alternative statement of willingness to pay fees as high as 
anticipated by the Department.
    (iv) A request seeking a fee waiver shall, to the extent possible, 
address why the requester believes that the criteria for fee waivers 
set out in Sec. 7.44(f) are met.
    (d) Creation of records. A request may seek only records that are 
in existence at the time the request is received. A request may not 
seek records that come into existence after the date on which it is 
received and may not require that new records be created in response to 
the request by, for example, combining or compiling selected items from 
manual files, preparing a new computer program, or calculating 
proportions, percentages, frequency distributions, trends, or 
comparisons. In those instances where the Department determines that 
creating a new record will be less burdensome than disclosing large 
volumes of unassembled material, the Department may, in its discretion, 
agree to creation of a new record as an alternative to disclosing 
existing records.
    (e) Each record made available under this subpart will be made 
available for inspection and copying during regular business hours at 
the place where it is located, or photocopying may be arranged with the 
copied materials being mailed to the requester upon payment of the 
appropriate fee. Original records ordinarily will be copied except in 
this instances where, in the Department's judgment, copying would 
endanger the quality of the original or raise the reasonable 
possibility of irreparable harm to the record. In these instances, 
copying of the original would not be in the public interest. In any

[[Page 33079]]

event, original records will not be released from Department custody.
    (f) If a requested record is known not to exist in the files of the 
agency, or to have been destroyed or otherwise disposed of, the 
requester will be so notified.
    (g) Fees will be determined in accordance with subpart F of this 
part.
    (h) Notwithstanding paragraphs (a) through (g) of this section, 
informational material, such as news releases, pamphlets, and other 
materials of that nature that are ordinarily made available to the 
public as a part of any information program of the Government will be 
available upon oral or written request. A fee will not be charged for 
individual copies of that material so long as the material is in 
supply. In addition the Department will continue to respond, without 
charge, to routine oral or written inquiries that do not involve the 
furnishing of records.

Sec. 7.15   Contacts for Records Requested Under the FOIA.

    Each person desiring a record under this subpart should submit a

    (e) If the person making the request does not know where in the 
Department the record is located, he or she may make inquiry to the

Sec. 7.16   Requests for Records of Concern to More Than One Government 
Organization.

    (a) If the release of a record covered by this subpart would be of 
concern to both this Department and another Federal agency, the 
determination as to release will be made only after consultation with 
the other interested agency.
    (b) If the release of the record covered by this subpart would be 
of concern to both this Department and a State or local government, a 
territory or possession of the United States, or a foreign government, 
the determination as to release will be made by the Department only 
after consultation with the other interested State or local government 
or foreign government.
    (c) As an alternative to consultation, the Department may refer the 
request (or relevant portion thereof) to a Federal agency that 
originated or is substantially concerned with the records. Such 
referrals shall be made expeditiously and the requester shall be 
notified in writing that a referral has been made.

Sec. 7.17  Consultation With Submitters of Commercial and Financial 
Information.

    (a) If a request is received for information that has been 
designated by the submitter as confidential commercial information, or 
which the Department has some other reason to believe may contain trade 
secrets or other commercial or financial information of the type 
described in Sec. 7.13(c)(4), the submitter of such information will, 
except as is provided in paragraphs (c) and (d) of this section, be 
notified expeditiously and asked to submit any written objections to 
release. At the same time, the requester will be notified that notice 
and an opportunity to comment are being provided to the submitter. The 
submitter will, to the extent permitted by law, be afforded a 
reasonable period of time within which to provide a detailed statement 
of any such objections. The submitter's statement shall specify all 
grounds for withholding any of the information. The burden shall be on 
the submitter to identify all information for which exempt treatment is 
sought and to persuade the agency that the information should not be 
disclosed.
    (b) The Office of the Secretary or the responsible operating 
element, as appropriate, will, to the extent permitted by law, consider 
carefully a submitter's objections and specific grounds for 
nondisclosure prior to determining whether to disclose business 
information. Whenever a decision is made to disclose such information 
over the objection of a submitter, the office responsible for the 
decision will forward to the submitter a written notice that will 
include:
    (1) A statement of the reasons for which the submitter's disclosure 
objections were not accepted;
    (2) A description of the business information to be disclosed; and
    (3) A specific disclosure date. Such notice of intent to disclose 
will, to the extent permitted by law, be forwarded to the submitter a 
reasonable number of days prior to the specified date upon which 
disclosure is intended. At the same time the submitter is notified, the 
requester will be notified of the decision to disclose information.
    (c) The notice requirements of this section will not apply if:
    (1) The office responsible for the decision determines that the 
information should not be disclosed;
    (2) The information lawfully has been published or otherwise made 
available to the public; or
    (3) Disclosure of the information is required by law (other than 5 
U.S.C. 552).
    (d) The procedures established in this section shall not apply in 
the case of:
    (1) Business information submitted to the National Highway Traffic 
Safety Administration and addressed in 49 CFR part 512.
    (2) Information contained in a document to be filed or in oral 
testimony that is sought to be withheld pursuant to Rule 39 of the 
Rules of Practice (14 CFR 302.39) in Aviation Economic Proceedings.
    (e) Whenever a requester brings suit seeking to compel disclosure 
of confidential commercial information, the Office of the Secretary or 
the responsible operating element, whichever the case may be, will 
promptly notify the submitter.

Subpart  D--Procedures for Appealing Decisions Not To Disclose 
Records and/or Waive Fees

Sec. 7.21  General.

    (a) Each officer or employee of the Department who, upon a request 
by a member of the public for a record under this part, makes a 
determination that the record is not to be disclosed, either because it 
is subject to an exemption or not in the Department's custody and 
control, will give a written statement of the reasons for that 
determination to the person making the request; and indicate the names 
and titles or positions of each person responsible for the initial 
determination not to comply with such

[[Page 33080]]

request, and the availability of an appeal within the Department.
    (b) When a request for a waiver of fees, pursuant to Sec. 7.44, has 
been denied in whole or in part, the requester may appeal the denial.
    (c) Any person to whom a record has not been made available within 
the time limits established by Sec. 7.31 and any person who has been 
given a determination pursuant to paragraph (a) of this section that a 
record will not be disclosed may appeal to the head of the operating 
element concerned or, in the case of the Office of the Secretary, to 
the General Counsel of the Department, and in the case of the Office of 
Inspector General, to the Inspector General. Any person who has not 
received an initial determination on his or her request within the time 
limits established by Sec. 7.31 can seek immediate judicial review, 
which may be sought without the need first to submit an administrative 
appeal. Judicial review may be sought in the United States District 
Court for the judicial district in which the requester resides or has 
his or her principal place of business, the judicial district in which 
the records are located, or in the District of Columbia. A 
determination that a record will not be disclosed and/or that a request 
for a fee waiver or reduction will not be granted does not constitute 
final agency action for the purposes of judicial review unless:
    (1) It was made by the head of the operating element concerned (or 
his or her designee), or the General Counsel or the Inspector General, 
as the case may be; or
    (2) The applicable time limit has passed without a determination on 
the initial request or the appeal, as the case may be, having been 
made.
    (d) Each appeal must be made in writing within thirty days from the 
date of receipt of the original denial and should include all 
information and arguments relied upon by the person making the request. 
Such letter should indicate that it is an appeal from a denial of a 
request made under the Freedom of Information Act. The envelope in 
which the appeal is sent should be prominently marked: ``FOIA Appeal.'' 
If these requirements are not met, the twenty-day limit described in 
Sec. 7.32 will not begin to run until the appeal has been identified, 
or would have been identified with the exercise of due diligence, by an 
employee of the Department as an appeal under the Freedom of 
Information Act, and has been received by the appropriate office.
    (e) Whenever the head of the operating element concerned, or the 
General Counsel or the Inspector General, as the case may be, 
determines it to be necessary, he/she may require the person making the 
request to furnish additional information, or proof of factual 
allegations, and may order other proceedings appropriate in the 
circumstances. The decision of the head of the operating element 
concerned, or the General Counsel or the Inspector General, as the case 
may be, as to the availability of the record or the appropriateness of 
a fee waiver or reduction constitutes final agency action for the 
purpose of judicial review.
    (f) The decision of the head of the operating element concerned, or 
the General Counsel or Inspector General, as the case may be, not to 
disclose a record under this part or not to grant a request for a fee 
waiver or reduction is considered to be a denial by the Secretary for 
the purpose of 5 U.S.C. 552(a)(4)(B).
    (g) Any final determination by the head of an operating element or 
his or her delegate, not to disclose a record under this part, or not 
to grant a request for a fee waiver or reduction, is subject to 
concurrence by the General Counsel or his/her designee.
    (h) Upon a determination that an appeal will be denied, the 
requester will be informed in writing of the reasons for the denial of 
the request and the names and titles or positions of each person 
responsible for the determination, and that judicial review of the 
determination is available in the United States District Court for the 
judicial district in which the requester resides or has his or her 
principal place of business, the judicial district in which the 
requested records are located, or the District of Columbia.

Subpart E--Time Limits

Sec. 7.31  Initial Determinations.

    An initial determination whether to release a record requested 
pursuant to subpart C will be made within ten Federal working days 
after the request is received by the appropriate office in accordance 
with Sec. 7.14, except that this time limit may be extended by up to 
ten Federal working days in accordance with Sec. 7.33. The person 
making the request will be notified immediately of such determination. 
If the determination is to grant this request, the desired record will 
be made available as promptly as possible. If the determination is to 
deny the request, the person making the request will be notified in 
writing, at the same time he or she is notified of such determination, 
of the reason for the determination, the right of such person to appeal 
the determination, and the name and title of each person responsible 
for the initial determination to deny the request.

Sec. 7.32  Final Determination.

    A determination with respect to any appeal made pursuant to 
Sec. 7.21 will be made within twenty Federal working days after receipt 
of such appeal except that this time limit may be extended by up to ten 
Federal working days in accordance with Sec. 7.33. The person making 
the request will be notified immediately of such determination pursuant 
to Sec. 7.21.

Sec. 7.33  Extension.

    In unusual circumstances as specified in this section, the time 
limits prescribed in Sec. 7.31 and Sec. 7.32 may be extended by written 
notice to the person making the request setting forth the reasons for 
such extension and the date on which a determination is expected to be 
dispatched. Such notice may not specify a date that would result in a 
cumulative extension of more than ten Federal working days. As used in 
this subparagraph, ``unusual circumstances'' means, but only to the 
extent reasonably necessary to the proper processing of the particular 
request:
    (a) The need to search for and collect the requested records from 
field facilities or other establishments that are separate from the 
office processing the request.
    (b) The need to search for, collect, and appropriately examine a 
voluminous amount of separate and distinct records that are demanded in 
a single request; or
    (c) The need for consultation, which will be conducted with all 
practicable speed, with any other agency or DOT element having a 
substantial interest in the determination of the request or among two 
or more components of the agency having substantial subject-matter 
interest therein.

Subpart F--Fees

Sec. 7.41  General.

    (a) This subpart prescribes fees for services performed for the 
public under subparts B and C of this part by the Department.
    (b) All terms defined by the Freedom of Information Act apply to 
this subpart, and the term ``hourly rate'' means the actual hourly base 
pay for a civilian employee or, for members of the Coast Guard, the 
equivalent hourly pay rate computed using a 40-hour week and the 
member's normal basic pay and allowances.
    (c) This subpart applies to all employees of the Department, 
including those of non-appropriated fund

[[Page 33081]]

activities of the Coast Guard and the Maritime Administration.
    (d) This subpart does not apply to any special study, special 
statistical compilation, table, or other record requested under 49 
U.S.C. 329(c). The fee for the performance of such a service is the 
actual cost of the work involved in compiling the record. All such fees 
received by the Department in payment of the cost of such work are 
deposited in a separate account administered under the direction of the 
Secretary, and may be used for the ordinary expenses incidental to 
providing the information.
    (e) This subpart does not apply to requests from record subjects 
for records about themselves in Departmental systems of records. Fees 
for such requests are to be determined in accordance with the Privacy 
Act of 1974, as implemented by Department of Transportation regulations 
(49 CFR part 10).

Sec. 7.42  Payment of Fees.

    (a) The fees prescribed in this subpart may be paid by check, 
draft, or money order, payable to the Treasury of the United States; 
except that, in the case of the Saint Lawrence Seaway Development 
Corporation, all fees resulting from a request to that operating 
element shall be made payable to the Saint Lawrence Seaway Development 
Corporation.
    (b) Charges may be assessed by the Department for time spent 
searching for requested records even if the search fails to locate 
records or the records located are determined to be exempt from 
disclosure. In addition, if records are requested for commercial use, 
the Department may assess a fee for time spent reviewing any responsive 
records located to determine whether they are exempt from disclosure.
    (c) When it is estimated that the search charges, review charges, 
duplication fees or any combination of fees that could be charged to 
the requester will likely exceed $25, the requester will be notified of 
the estimated amount of the fees, unless the requester has indicated in 
advance his or her willingness to pay fees as high as those 
anticipated. The notice will also inform the requester how to consult 
with the appropriate Departmental officials with the object of 
reformulating the request to meet his or her needs at a lower cost.
    (d) Payment of fees may be required by the Department prior to 
actual duplication or delivery of any releasable records to a 
requester. However, advance payment of fees, i.e., payment before work 
is commenced or continued on a request, may not be required unless:
    (1) Allowable charges that a requester may be required to pay are 
likely to exceed $250; or
    (2) The requester has failed to pay within 30 days of the billing 
date fees charged for a previous request to any part of the Department.
    (e) When paragraph (d)(1) of this section applies, the requester 
will be notified of the likely cost and, where he/she has a history of 
prompt payment of FOIA fees, requested to furnish satisfactory 
assurance of full payment of FOIA fees. Where the requestor does not 
have any history of payment, he or she may be required to make advance 
payment of any amount up to the full estimated charges.
    (f) When paragraph (d)(2) of this section applies, the requester 
will be required to demonstrate that the fee has, in fact, been paid or 
to pay the full amount owed, including any applicable interest, late 
handling charges, and penalty charges as discussed below. The requester 
will also be required to make an advance payment of the full amount of 
the estimated fee before processing of a new request or continuation of 
a pending request is begun.
    (g) The Department will assess interest on an unpaid bill starting 
on the 31st day following the day on which the notice of the amount due 
is first mailed to the requester. Interest will accrue from the date of 
the notice of amount due and will be at the rate prescribed in 31 
U.S.C. 3717. Receipt by the Department of a payment for the full amount 
of the fees owed within 30 calendar days after the date of the initial 
billing will stay the accrual of interest, even if the payment has not 
been processed.
    (h) If payment of fees charged is not received within 30 calendar 
days after the date the initial notice of the amount due is first 
mailed to the requester, an administrative charge will be assessed by 
the Department to cover the cost of processing and handling the 
delinquent claim. In addition, a penalty charge will be applied with 
respect to any principal amount of a debt that is more than 90 days 
past due. Where appropriate, other steps permitted by Federal debt 
collection statutes, including disclosure to consumer reporting 
agencies and use of collection agencies, will be used by the Department 
to encourage payment of amounts overdue.
    (i) In any instance where the Department reasonably believes that a 
requester or a group of requesters acting in concert is attempting to 
break down a single FOIA request into a series of requests for the sole 
purpose of evading the payment of otherwise applicable fees, the 
Department will aggregate the requests and determine the applicable 
fees on the basis of the aggregation.
    (j) Notwithstanding any other provision of this subpart, when the 
total amount of fees that could be charged for a particular request (or 
aggregation of requests) under subpart C, after taking into account all 
services that must be provided free of, or at a reduced, charge, is 
less than $10.00 the Department will not make any charge for fees.

Sec. 7.43  Fee Schedule.

    (a) The standard fee for a manual search to locate a record 
requested under subpart C of this part, including making it available 
for inspection, will be determined by multiplying each searcher's 
hourly rate plus 16 percent by the time spent conducting the search.
    (b) The standard fee for a computer search for a record requested 
under subpart C of this part is the actual cost. This includes the cost 
of operating the central processing unit for the time directly 
attributable to searching for records responsive to a FOIA request and 
the operator/programmer salary (hourly plus 16 percent) costs 
apportionable to the search.
    (c) The standard fee for review of records requested under subpart 
C of this part is the reviewer's hourly rate plus 16 percent multiplied 
by the time he or she spent determining whether the requested records 
are exempt from mandatory disclosure.
    (d) The standard fee for duplication of a record requested under 
subpart C of this part is determined as follows:
    (1) Per copy of each page (not larger than 8 1/2 x 14 inches) 
reproduced by photocopy or similar methods (includes costs of personnel 
and equipment)--$0.10.
    (2) Per copy prepared by computer such as tapes or printout--actual 
costs, including operator time.
    (3) Per copy prepared by any other method of duplication--actual 
direct cost of production.
    (e) Depending upon the category of requester, and the use for which 
the records are requested, in some cases the fees computed in 
accordance with the above standard fee schedule will either be reduced 
or not charged, as prescribed by other provisions of this subpart.
    (f) The following special services not required by the FOIA may be 
made available upon request, at the stated fees: Certified copies of 
documents, with Department of Transportation or operating element seal 
(where authorized)--$4.00; or true copy, without seal--$2.00

[[Page 33082]]

Sec. 7.44  Services Performed Without Charge or at a Reduced Charge.

    (a) A fee is not to be charged to any requester making a request 
under subpart C for the first two hours of search time unless the 
records are requested for commercial use. For purposes of this subpart, 
when a computer search is required two hours of search time will be 
considered spent when the hourly costs of operating the central 
processing unit used to perform the search added to the computer 
operator's salary cost (hourly rate plus 16 percent) equals two hours 
of the computer operator's salary costs (hourly rate plus 16 percent).
    (b) A fee is not to be charged for any time spent searching for a 
record requested under subpart C if the records are not for commercial 
use and the requester is a representative of the news media, an 
educational institution whose purpose is scholarly research, or a non-
commercial scientific institution whose purpose is scientific research.
    (c) A fee is not to be charged for duplication of the first 100 
pages (standard paper, not larger than 8.5 x 14 inches) of records 
provided to any requester in response to a request under subpart C 
unless the records are requested for commercial use.
    (d) A fee is not to be charged to any requester under subpart C to 
determine whether a record is exempt from mandatory disclosure unless 
the record is requested for commercial use. A review charge may not be 
charged except with respect to an initial review to determine the 
applicability of a particular exemption to a particular record or 
portion of a record. A review charge may not be assessed for review at 
the administrative appeal level. When records or portions of records 
withheld in full under an exemption that is subsequently determined not 
to apply are reviewed again to determine the applicability of other 
exemptions not previously considered, this is considered an initial 
review for purposes of assessing a review charge.
    (e) Documents will be furnished without charge or at a reduced 
charge if the official having initial denial authority determines that 
disclosure of the information is in the public interest because it is 
likely to contribute significantly to public understanding of the 
operations or activities of the government and is not primarily in the 
commercial interest of the requester.
    (f) Factors to be considered by officials of the Department 
authorized to determine whether a waiver or reduction of fees will be 
granted include:
    (1) Whether the subject matter of the requested records concerns 
the operations or activities of the Federal government;
    (2) Whether the disclosure is likely to contribute to an 
understanding of Federal government operations or activities;
    (3) Whether disclosure of the requested information will contribute 
to the understanding of the public at large, as opposed to the 
individual understanding of the requester or a narrow segment of 
interested persons;
    (4) Whether the contribution to public understanding of Federal 
government operations or activities will be significant;
    (5) Whether the requester has a commercial interest that would be 
furthered by the requested disclosure; and
    (6) Whether the magnitude of any identified commercial interest to 
the requester is sufficiently large in comparison with the public 
interest in disclosure that disclosure is primarily in the commercial 
interest of the requester.

Sec. 7.45  Transcripts.

    Transcripts of hearings or oral arguments are available for 
inspection. Where transcripts are prepared by a nongovernmental 
contractor, and the contract permits the Department to handle the 
reproduction of further copies, Sec. 7.43 applies. Where the contract 
for transcription services reserves the sales privilege to the 
reporting service, any duplicate copies must be purchased directly from 
the reporting service.

Sec. 7.46  Alternative Sources of Information.

    In the interest of making documents of general interest publicly 
available at as low a cost as possible, alternative sources shall be 
arranged whenever possible. In appropriate instances, material that is 
published and offered for sale may be obtained from the Superintendent 
of Documents, U.S. Government Printing Office, Washington, DC 20402; 
U.S. Department of Commerce's National Technical Information Service 
(NTIS), Springfield, Virginia 22151; or National Audio-Visual Center, 
National Archives and Records Administration, Capital Heights, MD

Airworthiness Directives; Boeing Model 737-300, -400, and -500 
Series Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: This document proposes the adoption of a new airworthiness 
directive (AD) that is applicable to certain Boeing Model 737-300, -
400, and -500 series airplanes. This proposal would require inspections 
to detect bent or damaged tie links and washers of the elevator feel 
and centering unit, and replacement of the centering unit with a new or 
serviceable unit, if necessary. This action also would provide an 
optional replacement of the centering unit, which, if accomplished with 
the installation of supports and a stop bolt, would constitute 
terminating action for the repetitive inspections. This proposal is 
prompted by a report of high control column forces that occurred during 
takeoff and landing. The actions specified by the proposed AD are 
intended to prevent such high forces, which could result in restriction 
of elevator control during takeoff, climbout, and landing.

DATES: Comments must be received by August 5, 1996.

ADDRESSES: Submit comments in triplicate to the Federal Aviation 
Administration (FAA), Transport Airplane Directorate, ANM-103, 
Attention: Rules Docket No. 96-NM-23-AD, 1601 Lind Avenue, SW., Renton, 
Washington 98055-4056. Comments may be inspected at this location 
between 9:00 a.m. and 3:00 p.m., Monday through Friday, except Federal 
holidays.
    The service information referenced in the proposed rule may be 
obtained from Boeing Commercial Airplane Group, P.O. Box 3707, Seattle, 
Washington 98124-2207. This information may be examined at the FAA, 
Transport Airplane Directorate, 1601 Lind Avenue, SW., Renton, 
Washington.

Availability of NPRMs

    Any person may obtain a copy of this NPRM by submitting a request 
to the FAA, Transport Airplane Directorate, ANM-103, Attention: Rules 
Docket No. 96-NM-23-AD, 1601 Lind Avenue, SW., Renton, Washington 
98055-4056.

Discussion

    The FAA has received a report of high control column forces during 
takeoff and landing of a Model 737 series airplane. Investigation 
revealed that the high forces were caused by bent tie links in the 
elevator centering unit. Further investigation indicated that, when 
hydraulic pressure is removed from the elevator feel actuator, the 
actuator extends to its full length. If the control column is then 
pulled back to the aft stop and then pushed forward with sufficient 
force, the tie links in the centering unit can become bent. Bent tie 
links can cause the elevator control forces to be higher than normal. 
This will be noticeable when larger elevator inputs are necessary, such 
as during takeoff and landing. This condition, if not corrected, could 
result in restriction of elevator control during takeoff, climbout, and 
landing.

Explanation of Relevant Service Information

    The FAA has reviewed and approved Boeing Alert Service Bulletin 
737-27A1194, dated February 1, 1996, which describes procedures for 
repetitive visual inspections for bent or damaged tie links of the 
elevator feel and centering unit, and replacement of the centering unit 
with a new or serviceable unit, if necessary. The alert service 
bulletin also describes procedures for installation of supports and a 
stop-bolt on the elevator centering unit. Such installation eliminates 
the need for repetitive inspections for airplanes on which no damaged 
tie links or washers are found. The alert service bulletin also 
indicates that replacement of the elevator centering unit with a new 
unit, or one on which serviceable tie links, supports, and a stop-bolt 
are installed, would eliminate the need for the repetitive inspections.

Explanation of Requirements of Proposed Rule

    Since an unsafe condition has been identified that is likely to 
exist or develop on other products of this same type design, the 
proposed AD would require repetitive visual inspections to detect bent 
or damaged tie links of the elevator centering unit, and replacement of 
the elevator centering unit with a new or serviceable unit, if 
necessary. Replacement of the elevator centering unit with a new or 
serviceable unit on which serviceable tie links, supports, and a stop-
bolt are installed constitutes terminating action for the repetitive 
inspections. The actions would be required to be accomplished in 
accordance with the alert service bulletin described previously.

Cost Impact

    There are approximately 1,618 Boeing Model 737-300, -400, and -500 
series airplanes of the affected design in the worldwide fleet. The FAA 
estimates that 684 airplanes of U.S. registry would be affected by this 
proposed AD, that it would take approximately 3 work hours per airplane 
to accomplish the proposed actions, and that the average labor rate is 
$60 per work hour. Required parts would cost approximately $140 per 
airplane. Based on these figures, the cost impact of the proposed AD on 
U.S. operators is estimated to be $218,880, or $320 per airplane.
    The cost impact figure discussed above is based on assumptions that 
no operator has yet accomplished any of

[[Page 33050]]

the proposed requirements of this AD action, and that no operator would 
accomplish those actions in the future if this AD were not adopted.
    Should an operator elect to replace the elevator centering unit 
rather than continue the repetitive inspections, it would take 
approximately 10 work hours per airplane to accomplish the replacement, 
at an average labor rate of $60 per work hour. Required parts would 
cost approximately $640 per airplane. Based on these figures, the cost 
impact of the replacement is estimated to be $1,240 per airplane.

Regulatory Impact

    The regulations proposed herein would not have substantial direct 
effects on the States, on the relationship between the national 
government and the States, or on the distribution of power and 
responsibilities among the various levels of government. Therefore, in 
accordance with Executive Order 12612, it is determined that this 
proposal would not have sufficient federalism implications to warrant 
the preparation of a Federalism Assessment.
    For the reasons discussed above, I certify that this proposed 
regulation (1) is not a ``significant regulatory action'' under 
Executive Order 12866; (2) is not a ``significant rule'' under the DOT 
Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); 
and (3) if promulgated, will not have a significant economic impact, 
positive or negative, on a substantial number of small entities under 
the criteria of the Regulatory Flexibility Act. A copy of the draft 
regulatory evaluation prepared for this action is contained in the 
Rules Docket. A copy of it may be obtained by contacting the Rules 
Docket at the location provided under the caption ADDRESSES.

    Air transportation, Aircraft, Aviation safety, Safety.

The Proposed Amendment

    Accordingly, pursuant to the authority delegated to me by the 
Administrator, the Federal Aviation Administration proposes to amend 
part 39 of the Federal Aviation Regulations (14 CFR part 39) as 
follows:

PART 39--AIRWORTHINESS DIRECTIVES

    1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.

Sec. 39.13  [Amended]

    2. Section 39.13 is amended by adding the following new 
airworthiness directive:

Boeing: Docket 96-NM-23-AD.

    Applicability: Model 737-300, -400 and -500 series airplanes 
through line position 2764 inclusive; certificated in any category.
    Note 1: This AD applies to each airplane identified in the 
preceding applicability provision, regardless of whether it has been 
modified, altered, or repaired in the area subject to the 
requirements of this AD. For airplanes that have been modified, 
altered, or repaired so that the performance of the requirements of 
this AD is affected, the owner/operator must request approval for an 
alternative method of compliance in accordance with paragraph (f) of 
this AD. The request should include an assessment of the effect of 
the modification, alteration, or repair on the unsafe condition 
addressed by this AD; and, if the unsafe condition has not been 
eliminated, the request should include specific proposed actions to 
address it.

    Compliance: Required as indicated, unless accomplished 
previously.
    To prevent restriction of elevator control during takeoff, 
climbout, and landing, due to higher than normal elevator control 
forces caused by damaged tie links in the elevator centering unit, 
accomplish the following:
    (a) Within 6 months after the effective date of this AD: Perform 
a visual inspection to detect any bent or damaged tie links of the 
elevator feel and centering unit, in accordance with Boeing Alert 
Service Bulletin 737-27A1194, dated February 1, 1996.
    (b) If no tie link is found to be broken, bent, or damaged 
during the inspection required by paragraph (a) of this AD: 
Accomplish either paragraph (b)(1) or (b)(2) of this AD, in 
accordance with Boeing Alert Service Bulletin 737-27A1194, dated 
February 1, 1996:
    (1) Prior to further flight, install supports and a stop-bolt on 
the elevator centering unit. Once this installation is accomplished, 
no further action is required by this AD. Or
    (2) Repeat the inspection required by paragraph (a) of this AD 
thereafter at intervals not to exceed 1,000 flight cycles. 
Installation of supports and a stop-bolt in accordance with the 
alert service bulletin, constitutes terminating action for the 
repetitive inspections required by this AD, provided that no damage 
is detected during any inspection required by paragraph (a) of this 
AD.
    (c) If any tie link is found to be bent or damaged during the 
inspection required by paragraph (a) of this AD, and damage is 
within the limits specified in Figure 1 of Boeing Alert Service 
Bulletin 737-27A1194, dated February 1, 1996: Accomplish paragraphs 
(c)(1) and (c)(2) of this AD in accordance with the alert service 
bulletin:
    (1) Repeat the inspection required by paragraph (a) of this AD 
thereafter at intervals not to exceed those specified in Figure 1 of 
the alert service bulletin. And
    (2) Within 6 months after the effective date of this AD, install 
supports and a stop-bolt on the elevator centering unit. This 
installation does not terminate the repetitive inspection 
requirements of this paragraph.
    (d) If any tie link is found to be bent or damaged during any 
inspection required by this AD, and the damage is beyond the limits 
specified in Figure 1 of Boeing Alert Service Bulletin 737-27A1194, 
dated February 1, 1996: Prior to further flight, replace the 
elevator centering unit with a new or serviceable unit and 
accomplish either paragraph (d)(1) or (d)(2) of this AD in 
accordance with the alert service bulletin:
    (1) Install supports and a stop-bolt on the elevator centering 
unit; or
    (2) Repeat the inspection required by paragraph (a) of this AD 
thereafter at intervals not to exceed 1,000 flight cycles until the 
installation specified in paragraph (d)(1) of this AD is 
accomplished.
    (e) Replacement of the elevator centering unit with a unit in 
which the tie links have been inspected and determined to be 
acceptable and in which supports and a stop-bolt have been 
installed, in accordance with Boeing Service Bulletin 737-27A1194, 
dated February 1, 1996, constitutes terminating action for the 
requirements of this AD.
    (f) An alternative method of compliance or adjustment of the 
compliance time that provides an acceptable level of safety may be 
used if approved by the Manager, Seattle Aircraft Certification 
Office (ACO), FAA, Transport Airplane Directorate. Operators shall 
submit their requests through an appropriate FAA Principal 
Maintenance Inspector, who may add comments and then send it to the 
Manager, Seattle ACO.

    Note 2: Information concerning the existence of approved 
alternative methods of compliance with this AD, if any, may be 
obtained from the Seattle ACO.

    (g) Special flight permits may be issued in accordance with 
sections 21.197 and 21.199 of the Federal Aviation Regulations (14 
CFR 21.197 and 21.199) to operate the airplane to a location where 
the requirements of this AD can be accomplished.

Airworthiness Directives; Boeing Model 747 Series Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: This document proposes the supersedure of an existing 
airworthiness directive (AD), applicable to certain Boeing Model 747 
and 767 series

[[Page 33051]]

airplanes, that currently requires inspection of the door opening 
thrusters and door opening/snubbing actuators for proper oil quantity, 
and modification of the off-wing compartment latching assemblies. This 
action would add a requirement for replacement of the currently 
installed door opening thrusters with new, improved thrusters for Model 
747 series airplanes. This action also would remove Model 767 series 
airplanes from the applicability of the existing AD. This proposal is 
prompted by reports indicating that the requirements of the existing AD 
do not adequately preclude leakage of fluid from the actuators. The 
actions specified by the proposed AD are intended to prevent such 
leakage, which could result in failure of the escape slide to deploy; 
such failure could delay and possibly jeopardize the successful 
emergency evacuation of an airplane.

Docket No. 95-NM-226-AD, 1601 Lind Avenue, SW., Renton, Washington 
98055-4056.

Discussion

    On July 15, 1992, the FAA issued AD 92-16-17, amendment 39-8327 (57 
FR 47987, October 21, 1992), which is applicable to certain Model 747 
and 767 series airplanes. That AD requires repetitive inspections 
(weighing program) of the door opening thrusters and door opening/
snubbing actuators for proper oil quantity, and modification of the 
off-wing compartment latching assemblies. That action was prompted by 
reports of failure of the off-wing escape slide system to deploy when 
commanded. The requirements of that AD are intended to prevent such 
failure, which could delay and possibly jeopardize the successful 
emergency evacuation of an airplane.

Actions Since Issuance of Previous Rule

    Since the issuance of that AD, the FAA received a report from an 
operator of Model 767 series airplanes indicating that several 
actuators leaked following accomplishment of the modification required 
by AD 92-16-17. Consequently, the FAA determined that the modification 
requirements of that AD do not adequately preclude leakage from the 
actuators. Additionally, the operator reported that, during inspections 
(weighing program) of the actuators, the weight of several actuators 
increased from the original weight measured during the initial 
inspection required by AD 92-16-17. Therefore, the FAA determined that 
the inspection requirements of AD 92-16-17 cannot reliably determine 
the fluid level of these actuators.
    Subsequently, the manufacturer developed a new, improved actuator 
for Model 767 series airplanes. On April 10, 1995, the FAA issued AD 
95-08-11, amendment 39-9200 (60 FR 20013, April 24, 1995), to require 
replacement of the currently installed door opening actuators of the 
off-wing emergency escape system on Model 767 series airplanes with 
new, improved actuators. Accomplishment of that replacement constitutes 
terminating action for the repetitive inspections (weighing program) of 
the door opening/snubbing actuators for those airplanes. The FAA 
indicated in AD 95-08-11 that it was considering a separate rulemaking 
action to remove the requirements for Model 767 series airplanes from 
AD 92-16-17.
    The door opening thrusters installed on Model 747 series airplanes 
are similar in design to the door opening/snubbing actuators installed 
on Model 767 series airplanes in that both require a small quantity of 
oil to operate, and both have a tendency to leak oil from the chamber. 
Such leakage can result in failure of an actuator or thruster.

Explanation of Relevant Service Information

    Boeing has issued Service Bulletin 747-25-3073, dated September 21, 
1995, which describes procedures for replacement of existing door 
opening thrusters on Model 747 series airplanes with new, improved 
thrusters. Since the new, improved thruster is not fluid filled, 
accomplishment of the replacement eliminates the need for inspections 
of the door opening thrusters and door opening/snubbing actuators for 
proper oil quantity.

Explanation of Requirements of Proposed Rule

    Since an unsafe condition has been identified that is likely to 
exist or develop on other products of this same type design, the 
proposed AD would supersede AD 92-16-17 to continue to require 
repetitive inspections of the door opening thrusters and door opening/
snubbing actuators for proper oil quantity, and modification of the 
off-wing compartment latching assemblies for Model 747 series 
airplanes. For those airplanes, this proposed AD would add a 
requirement for replacement of existing door opening thrusters with 
new, improved thrusters. Accomplishment of the replacement constitutes 
terminating action for the repetitive inspections. The actions would be 
required to be accomplished

[[Page 33052]]

in accordance with the service bulletin described previously.
    Additionally, the proposed AD would remove Model 767 series 
airplanes from the applicability of the existing AD, since the subject 
unsafe condition on those airplanes is addressed in AD 95-08-11.

Cost Impact

    There are approximately 400 Model 747 series airplanes of the 
affected design in the worldwide fleet. The FAA estimates that 125 
airplanes of U.S. registry would be affected by this proposed AD.
    The actions that are currently required by AD 92-16-17 take 
approximately 12 work hours per airplane to accomplish, at an average 
labor rate of $60 per work hour. Required parts cost approximately $510 
per airplane. Based on these figures, the cost impact on U.S. operators 
of the actions currently required is estimated to be $153,750, or 
$1,230 per airplane.
    The new actions that are proposed in this AD action would take 
approximately 2 work hours per airplane to accomplish, at an average 
labor rate of $60 per work hour. Required parts would cost 
approximately $6,400 per airplane. Based on these figures, the cost 
impact on U.S. operators of the proposed requirements of this AD is 
estimated to be $815,000, or $6,520 per airplane.
    The cost impact figures discussed above are based on assumptions 
that no operator has yet accomplished any of the current or proposed 
requirements of this AD action, and that no operator would accomplish 
those actions in the future if this AD were not adopted.

Regulatory Impact

    The regulations proposed herein would not have substantial direct 
effects on the States, on the relationship between the national 
government and the States, or on the distribution of power and 
responsibilities among the various levels of government. Therefore, in 
accordance with Executive Order 12612, it is determined that this 
proposal would not have sufficient federalism implications to warrant 
the preparation of a Federalism Assessment.
    For the reasons discussed above, I certify that this proposed 
regulation (1) is not a ``significant regulatory action'' under 
Executive Order 12866; (2) is not a ``significant rule'' under the DOT 
Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); 
and (3) if promulgated, will not have a significant economic impact, 
positive or negative, on a substantial number of small entities under 
the criteria of the Regulatory Flexibility Act. A copy of the draft 
regulatory evaluation prepared for this action is contained in the 
Rules Docket. A copy of it may be obtained by contacting the Rules 
Docket at the location provided under the caption ADDRESSES.

The Proposed Amendment

    Accordingly, pursuant to the authority delegated to me by the 
Administrator, the Federal Aviation Administration proposes to amend 
part 39 of the Federal Aviation Regulations (14 CFR part 39) as 
follows:

PART 39--AIRWORTHINESS DIRECTIVES

    1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.

Sec. 39.13  [Amended]

    2. Section 39.13 is amended by removing amendment 39-8327 (57 FR 
47987, October 21, 1992), and by adding a new airworthiness directive 
(AD), to read as follows:

Boeing: Docket 95-NM-226-AD. Supersedes AD 92-16-17, Amendment 39-
8327.

    Applicability: Model 747-100, -200, and -300 series airplanes 
equipped with an off-wing, two-piece escape slide on Door 3; 
certificated in any category.

    Note 1: This AD applies to each airplane identified in the 
preceding applicability provision, regardless of whether it has been 
otherwise modified, altered, or repaired in the area subject to the 
requirements of this AD. For airplanes that have been modified, 
altered, or repaired so that the performance of the requirements of 
this AD is affected, the owner/operator must request approval for an 
alternative method of compliance in accordance with paragraph (e) of 
this AD. The request should include an assessment of the effect of 
the modification, alteration, or repair on the unsafe condition 
addressed by this AD; and, if the unsafe condition has not been 
eliminated, the request should include specific proposed actions to 
address it.

    Compliance: Required as indicated, unless accomplished 
previously.
    To prevent failure of the escape slide to deploy, which could 
delay and possibly jeopardize the successful emergency evacuation of 
an airplane, accomplish the following:
    (a) Within 18 months after November 25, 1992 (the effective date 
of AD 92-16-17, amendment 39-8327), perform an inspection of the 
door opening thrusters of the escape system in accordance with OEA 
Service Bulletin 2174200-25-013, dated July 29, 1991. Repeat this 
inspection thereafter at intervals not to exceed 20 months until the 
replacement required by paragraph (c) of this AD is accomplished.
    (b) Within 18 months after November 25, 1992, inspect and modify 
the door latching mechanism of the escape slide compartment in 
accordance with Boeing Service Bulletin 747-25-2951, dated August 
15, 1991.
    (c) Within 2 years after the effective date of this AD, replace 
the door opening thrusters having part number (P/N) 60B50077-14 or -
17 with new thrusters having P/N 60B50077-19 in accordance with 
Boeing Service Bulletin 747-25-3073, dated September 21, 1995. 
Accomplishment of this replacement terminates the repetitive 
inspections required by this AD.
    (d) As of the effective date of this AD, no person shall install 
a door opening thruster having P/N 60B50077-14 or -17 on any 
airplane.
    (e) An alternative method of compliance or adjustment of the 
compliance time that provides an acceptable level of safety may be 
used if approved by the Manager, Seattle Aircraft Certification 
Office (ACO), FAA, Transport Airplane Directorate. Operators shall 
submit their requests through an appropriate FAA Principal 
Maintenance Inspector, who may add comments and then send it to the 
Manager, Seattle ACO.

    Note 2: Information concerning the existence of approved 
alternative methods of compliance with this AD, if any, may be 
obtained from the Seattle ACO.

    (f) Special flight permits may be issued in accordance with 
sections 21.197 and 21.199 of the Federal Aviation Regulations (14 
CFR 21.197 and 21.199) to operate the airplane to a location where 
the requirements of this AD can be accomplished.

Hearing and Reopening of Comment Period on Proposed Threatened and 
Endangered Status for Five Plants and a Lizard From Monterey County, 
California

AGENCY: Fish and Wildlife Service, Interior.

ACTION: Proposed Rule; notice of public hearing and reopening of 
comment period.

-----------------------------------------------------------------------

SUMMARY: The Fish and Wildlife Service (Service), pursuant to the 
Endangered Species Act of 1973, as amended (Act), provides notice of a 
public hearing on the proposed endangered status for coastal dunes 
milkvetch (Astragalus tener var. titi), Yadon's piperia (Piperia 
yadonii), Hickman's potentilla (Potentilla hickmanii), Monterey clover 
(Trifolium trichocalyx) and the black legless lizard (Anniella pulchra 
nigra); and threatened status for Gowen cypress (Cupressus goveniana 
ssp. goveniana). In addition, the Service has reopened the comment 
period. All parties are invited to submit comments on this proposal.

DATES: The public hearing will be held from 6 p.m. to 8 p.m. on 
Wednesday, July 17, 1996, in Monterey, California. The public comment 
period now closes August 30, 1996. Any comments received by the closing 
date will be considered in the final decision on this proposal.

ADDRESSES: The public hearing will be held at the Hyatt Regency Hotel, 
One Golf Course Road, Monterey, California. Written comments and 
materials concerning this proposal may be submitted at the hearing or 
sent directly to the Field Supervisor, Ventura Field Office, 2493 
Portola Road, Suite B, Ventura, California 93003. Comments and 
materials will be available for public inspection, by appointment, 
during normal business hours at the above address.

Connie Rutherford (see ADDRESSES section) or at 805/644-1766.

SUPPLEMENTARY INFORMATION:

Background

    Most of the habitat for the plants and lizard is found in coastal 
habitats in northern Monterey County. Coastal dunes milk-vetch and 
Monterey clover are restricted to private lands on the Monterey 
Peninsula. Hickman's potentilla is restricted to two populations: one 
on the Monterey

[[Page 33083]]

Peninsula, and one recently discovered near Devil's Slide in San Mateo 
County. Gowen cypress stands occur on the Monterey Peninsula, and at 
Point Lobos State Reserve five miles to the south. Yadon's piperia 
occurs primarily on private lands on the Monterey Peninsula, with other 
populations extending as far south as Palo Colorado Canyon, and as far 
north as Blohm Ranch north of Prunedale. The black legless lizard 
occurs on private and State Park lands between the Salinas and Carmel 
Rivers, on the Monterey Peninsula, and along Monterey Bay. A few 
populations of Yadon's piperia and the black legless lizard occur on 
Federal lands at Fort Ord.
    The five plant taxa and the lizard are threatened by one or more of 
the following: alteration, destruction, and fragmentation of habitat 
resulting from urban and golf course development; recreational 
activities; highway widening; military activities; competition with 
non-native species; and alteration of natural fire cycles. All taxa are 
also threatened with stochastic extinction due to the small numbers of 
populations or individuals.
    On August 2, 1995, the Service published a proposed rule on 
proposed endangered status for Astragalus tener var. titi, Piperia 
yadonii, Potentilla hickmanii, Trifolium trichocalyx, and the black 
legless lizard (Anniella pulchra nigra); and threatened status for 
Gowen cypress (Cupressus goveniana ssp. goveniana (60 FR 39326). 
Section 4(b)(5)(E) of the Act requires that a public hearing be held if 
one is requested within 45 days of the publication of the proposed rule 
in the Federal Register. Public hearing requests were received within 
the allotted time period from Robert D. Thornton of Nossaman, Guthner, 
Knox, and Elliot in Irvine, California. Because a Congressional 
moratorium on the Service's activities associated with final listing 
actions was in effect from April 1995 to April 1996, scheduling of the 
hearing had been delayed. The Service has scheduled a public hearing on 
July 17, 1996, at the Hyatt Regency Hotel, One Golf Course Road, 
Monterey, California.
    Anyone wishing to make statements for the record should bring a 
written copy of their statements to the hearing. Oral statements may be 
limited in length if the number of parties present at the hearing 
necessitates such a limitation. Oral and written comments receive equal 
consideration. The Service places no limits to the length of written 
comments or materials presented at the hearing or mailed to the 
Service. Legal notices announcing the date, time, and location of the 
hearing are being published in newspapers concurrently with this 
Federal Register notice.
    The comment period on the proposal was initially closed on October 
17, 1995. To accommodate the hearing, the public comment period is 
reopened upon publication of this notice. Written comments may now be 
submitted until August 30, 1996, to the Service office in the ADDRESSES 
section.

Authority

    The authority for this action is the Endangered Species Act of 1973 
(16 U.S.C. 1531 et seq.).

FEDERAL MARITIME COMMISSION

46 CFR Part 540

[Docket No. 94-06]

Financial Responsibility Requirements for Nonperformance of 
Transportation

AGENCY: Federal Maritime Commission.

ACTION: Further notice of proposed rulemaking.

-----------------------------------------------------------------------

SUMMARY: The Federal Maritime Commission proposes to remove its current 
$15 million coverage ceiling for nonperformance of transportation by 
passenger vessel operators. The Commission would replace the ceiling 
with sliding-scale coverage requirements keyed to passenger vessel 
operators' financial rating, length of operation in United States 
trades and satisfactory explanation of claims for nonperformance of 
transportation. For self-insuring passenger vessel operators, the 
Commission proposes to reestablish a working capital requirement and to 
require third-party coverage for 25 percent of unearned passenger 
revenue. In order to clarify that the escrow agreement is for the 
exclusive benefit of passengers' deposits and prepaid fares, the 
Commission proposes revising the form escrow agreement it publishes as 
a guideline for the industry. The Commission also proposes to require 
applications for Certificates (Performance) to be filed at least 90 
days in advance of the arranging, offering, advertising or providing of 
water transportation or tickets in connection therewith, unless good 
cause is shown. Finally, the Commission again solicits suggestions for 
other alternatives to consider under its Public Law 89-777 program, as 
well as suggestions for scheduling the phasing-in of the proposed 
rule's revised coverage requirements. These changes are deemed 
necessary to enhance the travelling public's protection against 
nonperformance of transportation.

DATES: Comments due on or before August 26, 1996.

SUPPLEMENTARY INFORMATION:

I. Introduction

    The Federal Maritime Commission (``Commission'' or ``FMC'') 
administers section 3, Public Law 89-777, 46 U.S.C. app. 817e 
(``section 3''). Section 3 requires certain passenger vessel operators 
(``PVOs'') 2 to establish financial responsibility for 
nonperformance of transportation.3 The Commission's regulations 
implementing section 3 (46 CFR 540, Subpart A) generally provide that a 
PVO may evidence financial responsibility by one or more of the 
following methods: A guaranty, escrow arrangement, surety bond, 
insurance or self-insurance. The Commission requires coverage of at 
least 110 percent of a PVO's highest unearned passenger revenue 
(``UPR'') 4 over a two-year period. However, the maximum coverage 
amount currently required is $15 million. Also, non-self-insuring PVOs 
that can evidence a minimum of five years operation in U.S. trades with 
a satisfactory explanation of any claims for nonperformance of 
transportation are entitled to reduced coverage requirements under the 
following sliding scale: 5
---------------------------------------------------------------------------

    \2\ For the purposes of section 3, a PVO is any person in the 
United States that arranges, offers, advertises or provides passage 
on a vessel having berth or stateroom accommodations for fifty or 
more passengers and which is to embark passengers at United States 
ports.
    \3\ Section 3 provides, in pertinent part:
    (a) No person in the United States shall arrange, offer, 
advertise, or provide passage on a vessel having berth or stateroom 
accommodations for fifty or more passengers and which is to embark 
passengers at United States ports without there first having been 
filed with the Federal Maritime Commission such information as the 
Commission may deem necessary to establish the financial 
responsibility of the person arranging, offering, advertising, or 
providing such transportation, or, in lieu thereof, a copy of a bond 
or other security, in such form as the Commission, by rule or 
regulation, may require and accept, for indemnification of 
passengers for nonperformance of the transportation.
    \4\ UPR is defined under 46 CFR 540.2(i) as:
    * * * passenger revenue received for water transportation and 
all other accommodations, services, and facilities relating thereto 
not yet performed.
    \5\ The Commission, in Docket No. 92-19, Revision of Financial 
Responsibility Requirements for Non-Performance of Transportation, 
amended 46 CFR Part 540, Subpart A, to (1) institute this sliding 
scale formula for determining the amount of financial responsibility 
coverage required for operators meeting certain requirements; (2) 
exclude, under certain conditions, revenue from ``whole-ship'' 
arrangements from being considered UPR; and (3) publish a suggested 
form escrow arrangement as a guideline for the industry (57 FR 51887 
(September 14, 1992)).

------------------------------------------------------------------------
 Unearned passenger revenue  (``UPR'')          Required coverage       
------------------------------------------------------------------------
$0-$5,000,000..........................  100% of UPR up to $5,000,000.  
$5,000,001 to $15,000,000..............  $5,000,000 plus 50% of excess  
                                          UPR over $5,000,000 subject to
                                          an overall maximum of         
                                          $5,000,000 per vessel.        
$15,000,001 to $35,000,000.............  $10,000,000 plus 25% of excess 
                                          of UPR over $15,000,000       
                                          subject to an overall maximum 
                                          of $5,000,000 per vessel and a
                                          $15,000,000 overall maximum.  
Over $35,000,000.......................  $15,000,000 overall maximum.   
------------------------------------------------------------------------

    Under the Commission's present rules, self-insuring PVOs are 
required to demonstrate, among other things, net worth equal to at 
least 110 percent of their UPR. At an earlier stage of this proceeding, 
as discussed below, the Commission had proposed to phase out self-
insurance except for PVOs which are state and Federal entities.
    The Commission monitors activity of PVOs who are subject to Public 
Law 89-777 and by rule requires semiannual UPR reports.6 
Additionally, the Commission periodically surveys PVOs' future U.S. 
cruise schedules and fare structures.
---------------------------------------------------------------------------

    \6\ 46 CFR 540.9(h) provides, in pertinent part:
    Every person who has been issued a Certificate (Performance) 
must submit to the Commission a semiannual statement of any changes 
that have taken place with respect to the information contained in 
the application or documents submitted in support thereof. Negative 
statements are required to indicate no change. Such statements must 
cover every 6-month period of the fiscal year immediately subsequent 
to the date of the issuance of the Certificate (Performance), and 
include a statement of the highest unearned passenger revenue 
accrued for each month in the 6-month reporting period. In addition, 
the statement will be due within 30 days after the close of every 
such 6-month period.
---------------------------------------------------------------------------

II. Background

A. Docket No. 94-6

    These proceedings were instituted with a March 1994 Notice of 
Proposed Rulemaking (``1994 NPR'' or ``1994 Proposed Rule'').7 The 
1994 NPR addressed the Commission's concerns about the adequacy of its 
coverage requirements in the light of several recent developments, 
including $700 million in uncovered UPR, the voluntary bankruptcy of 
one PVO and the dislocation of a self-insured carrier's operations as a 
result of the 1993 floods in the Mississippi River system. The 1994 NPR 
therefore proposed:
---------------------------------------------------------------------------

    \7\ 59 FR 15149 (March 31, 1994).
---------------------------------------------------------------------------

    (1) removing the current $15 million UPR coverage ceiling;
    (2) revising the current UPR sliding scale to require coverage of 
110 percent of UPR up to $25 million per operator, with coverage of 90 
percent of UPR for amounts exceeding $25 million (the NPR also put 
forth an alternative proposal which would require coverage of 110 
percent of UPR up to $25 million per operator; 75 percent of UPR 
between $25 million and $50 million per operator; and 50 percent 
coverage for UPR over $50 million per operator); and
    (3) removing self-insurance as an option for section 3 coverage 
(except for state or federal entities). Existing self-insured 
commercial operators would be provided one year following the effective 
date of any final rule in this matter to obtain other evidence of 
financial responsibility.
    The 1994 NPR drew twelve comments. There was virtually unanimous 
support for the Commission's existing coverage requirements, and 
widespread questioning of the need for the 1994 Proposed Rule. Many 
commenters drew attention to the Commission's earlier series of 
proceedings in this area,8 and

[[Page 33061]]

asserted that there have been no industry changes warranting this 
proposal. Positions ranged from strong Congressional and U.S.-flag PVO 
opposition to any further changes to current coverage requirements, to 
conditional support of a modified version of the 1994 Proposed Rule by 
foreign-flag interests. There was no support for the 1994 Proposed Rule 
outright; however, a foreign-flag PVO supported the 1994 Proposed 
Rule's coverage requirements for those PVOs unable to meet that PVO's 
self-insurance proposal.

B. Docket No. 94-21

    Given the concerns expressed in the industry comments to the 1994 
NPR, the Commission determined to hold it in abeyance pending a formal 
Inquiry under Docket No. 94-21, Inquiry into Alternative Forms of 
Financial Responsibility for Nonperformance of Transportation (``1994 
Inquiry'').9 The 1994 Inquiry's purpose was to determine whether 
an acceptable alternative could be fashioned to both address the 
industry's concerns with the 1994 NPR and ensure appropriate protection 
for passengers. The 1994 Inquiry therefore solicited comment on 
covering UPR liability through:
---------------------------------------------------------------------------

    \9\ 59 FR 52133 (October 26, 1994).
---------------------------------------------------------------------------

    (1) voluntary association(s) (such association(s) would be in 
addition to the current individual methods of evidencing financial 
responsibility for non-performance); 10 and
---------------------------------------------------------------------------

    \10\ In this connection, the Commission noted its approach in 
Docket No. 92-37, Financial Responsibility for Non-Vessel-Operating 
Common Carriers, Final Rule, 58 FR 5618 (January 22, 1993), which 
permits groups or associations of non-vessel-operating common 
carriers (``NVOCCs'') to collectively issue bonds to meet financial 
responsibility coverage requirements imposed upon NVOCCs by the 
Shipping Act of 1984. Because this approach had proven successful 
with respect to NVOCCs, a purpose of the 1994 Inquiry was to 
consider its applicability and adaptability to PVO requirements 
under Pub. L. 89-777.
---------------------------------------------------------------------------

    (2) retained but strengthened self-insurance requirements.
    In general terms, the association(s) envisioned by the 1994 Inquiry 
would accept liability for all or a part of a PVO's section 3 
liability, using a Commission-approved surety bond or guaranty in an 
amount equal to the combined UPR of the two members having the highest 
amount of UPR during the past two years. Because these associations 
would necessarily involve concerted carrier activity, comments were 
also invited on whether this approach could present issues under the 
antitrust laws, to the extent such activity is not immunized under 
Shipping Act agreements.\11\

    \11\ The Shipping Act of 1984, 46 U.S.C. app. 1701, (``1984 
Act'') governs concerted ocean common carrier activity in the U. S. 
foreign waterborne trades. The Shipping Act, 1916, 46 U.S.C. app. 
801, (``1916 Act'') governs concerted activity of common carriers by 
water in interstate commerce in the transportation by water of 
passengers on the high seas or the Great Lakes on regular routes 
from port to port between one U.S. State, Territory, District or 
possession and any other U.S. State, Territory, District or 
possession or between places in the same Territory, District or 
possession. Effective September 30, 1996, the ICC Termination Act of 
1995, Pub. L. No. 104-88, 109 Stat. 803, repeals among other things 
the 1916 Act provisions applicable to agreements.
---------------------------------------------------------------------------

    The reinforced self-insurance approach envisioned by the 1994 
Inquiry would have worked in a manner whereby the Commission would 
restore its former standard,\12\ but require prospective self-insurers 
to provide alternative coverage for a percentage (e.g., 50% or 25%) of 
their uncovered UPR, through either a traditional guaranty, surety, 
escrow agreement or lien or other security instrument, or through 
participation in a coverage association along the above-described 
lines. This approach would, however, still require qualifying assets to 
be located in the United States.
---------------------------------------------------------------------------

    \12\ The Commission previously required the maintenance of 
working capital and net worth, each equal to 110 percent of the 
operator's UPR. This standard provided that the Commission could, 
for good cause shown, waive the requirement as to the amount of 
working capital.
---------------------------------------------------------------------------

    The 1994 Inquiry was subsequently revised to clarify that the 
Commission was also seeking comment on accepting liens, mortgages or 
other security instruments as evidence of financial 
responsibility.13
---------------------------------------------------------------------------

    \13\ 59 FR 54878 (November 2, 1994).
---------------------------------------------------------------------------

    Five comments on the 1994 Inquiry were submitted by three trade 
associations (one representing surety interests,14 one 
representing foreign-flag vessel operators 15 and one representing 
U.S.-flag vessel operators)16, a foreign-flag vessel operator 
17 and a U.S.-flag vessel operator.18
---------------------------------------------------------------------------

    \14\ The Surety Association of America (``Surety Association'') 
is a trade association that represents 650 surety companies that 
provide 95% of the surety bonds written in the United States.
    \15\ The International Council of Cruise Lines (``ICCL'') states 
that its members have the vast majority of the cruise industry berth 
capacity. Its letterhead lists Carnival Cruise Lines; Celebrity 
Cruise Lines; Commodore Cruise Line; Costa Cruise Lines NV; Crown 
Cruise Line; Crystal Cruises; Cunard Line Ltd.; Dolphin Cruise Line; 
Epirotiki Lines; Fantasy Cruise Lines; Holland America Line; Majesty 
Cruise Line; Norwegian Cruise Line; Premier Cruise Lines, Ltd.; 
Princess Cruises; Regency Cruises, Inc. (``Regency''); Royal 
Caribbean Cruises, Ltd.; Royal Cruise Line; Royal Viking Line; 
Seabourn Cruise Line; Sun Line Cruises, Inc.; and Windstar Cruises.
    \16\ The Transportation Institute stated in its NPR comments 
that it represents 140 U.S.-flag shipping companies engaged in 
foreign and domestic trades, including American Classic Voyages Co. 
The U.S.-flag PVOs under the Commission's section 3 program 
presently consist of American Classic Voyages, Alaska Sightseeing/
Cruise West, Clipper Cruise Line, Special Expeditions, Alaska Marine 
Highway, and American Canadian Caribbean Line.
    \17\ Carnival Corporation (``Carnival''). Carnival's comments 
are filed on behalf of Carnival Cruise Lines, Holland America Lines 
and Windstar Cruises. Carnival is an ICCL member.
    \18\ American Classic Voyages Co. (``AMCV''). AMCV is the 
corporate parent of The Delta Queen Steamboat Co. (``Delta Queen'') 
and Great Hawaiian Cruise Line, Inc. (``American Hawaii''). AMCV is 
a section 3 self-insurer.
---------------------------------------------------------------------------

    All of the 1994 Inquiry's commenters had also commented on the NPR, 
and indicate that their comments on the 1994 Inquiry supplement or 
incorporate by reference those earlier comments, which generally 
opposed the 1994 Proposed Rule and urged retaining current regulations. 
Many commenters express appreciation for the Commission's efforts to 
arrive at creative solutions to the financial responsibility issue. At 
the same time, they reiterate their NPR comments that current 
requirements are working well, and that no passengers have lost any 
money.
    The commenters' general opposition to the NPR carried over to the 
alternatives proffered under the 1994 Inquiry: virtually all foresee 
problems of one sort or another with the voluntary association 
approach, ranging from skepticism about the availability of the large 
bonds necessary, to a number of difficult risk management and 
competitive factors. No commenter offers outright support for the 
vessel lien concept, for a number of reasons generally based on 
opposition to a requirement that qualifying assets be located in the 
U.S. Commenters urge the Commission not to change its current self-
insurance standards, or to discontinue the requirement that qualifying 
assets be based in the U.S.
1. Voluntary Associations
    The comments opposing the 1994 Inquiry's voluntary association 
proposal suggest that, although this general approach seems to be 
viable for NVOCCs, it may not be feasible for PVOs. In particular, 
these comments address the operational and fiscal

[[Page 33062]]

distinctions between the NVOCC and the PVO industries and make a 
credible argument as to why in this particular case a mechanism which 
works for one industry might not for another.19
---------------------------------------------------------------------------

    \19\ In this regard, the comments point out that P&I Clubs, 
which are mutual insurance associations, were developed initially to 
provide mutual insurance for casualty and other losses. Thus, they 
are structured on the assumption that a member will survive a 
casualty, and the P&I mechanism is designed to eventually recover 
casualty losses from the member suffering that loss. (P&I Clubs 
issue performance guaranties only as an accommodation to the 
membership, and then only on a fully-collateralized basis.) The 
NVOCC industry uses commercial instruments and does not have mutual 
associations similar to P&I Clubs.
---------------------------------------------------------------------------

    In short, the comments contend that an association approach would 
not work at the coverage levels contemplated under the NPR (either the 
original proposal or the alternative), due to the concentrated capital 
structures, operational diversity and competitive considerations 
inherent in the contemporary cruise industry.20 Also, ICCL 
comments that the nature of the cruise business does not lend itself to 
the mutuality inherent in the association approach, which seems to be 
borne out by AMCV's explanation of the drawbacks it sees in the 
association approach.21 It therefore appears unlikely that the 
market could support the magnitude of risk exposure inherent in the 
sort of voluntary association envisioned by the 1994 Inquiry.
---------------------------------------------------------------------------

    \20\ The Surety Association advises that, depending on the 
actual make-up and financial strength of the passenger vessel 
associations, some associations may find it extremely difficult to 
qualify for a group surety bond and some may not be able to qualify 
at all.
    \21\ AMCV described the undesirability of PVOs becoming exposed 
to liability for other PVOs' nonperformance; fiduciary risks to PVO 
management for assuming liability for events within the sole control 
of its competitors; the difficulties of allocating the levels of 
risk involved and the narrowness of the base upon which that risk 
would be shared; and the inherent susceptibility of weaker members 
to termination--either for competitive reasons or because of normal 
operational risks inherent in a seasonal industry that is ultimately 
dependent upon discretionary income for all of its revenues.
---------------------------------------------------------------------------

    Another material difference between these two industries is 
prepayment: NVOCCs do not require their customers to fully prepay for 
their services anywhere from two to six weeks (or, in some cases, eight 
or more weeks) before they are performed, as is the practice with PVOs. 
It is this practice which accounts for the approximately $700 million 
shortfall in uncovered UPR that prompted these proceedings. The 
shortfall's size more than anything else would appear ultimately to 
render the voluntary association approach unworkable.
    With regard to possible antitrust issues under this approach, AMCV 
notes that an association attempting to limit membership to financially 
sound PVOs could be subject to antitrust claims by excluded PVOs, and 
that there is an inherent potential for detrimental disclosure of 
confidential information.22
---------------------------------------------------------------------------

    \22\ Those PVOs subject to the 1984 Act could avail themselves 
of agreement immunity to protect themselves from whatever exposure 
such concerted activity would cause under antitrust laws. Thus, the 
Shipping Act's antitrust exemption could result in uneven antitrust 
exposure as between those PVOs entitled to the wide scope of 1984 
Act agreement antitrust exemption (transportation between U.S. and 
foreign locations), which would obtain either with the filing or 
regulatory exemption of the Association agreement(s); and those 
purely domestic PVOs (transportation solely within the U.S.), which 
may not be entitled to any Shipping Act antitrust exemption at all. 
(The immunity afforded by the 1916 Act is repealed September 30, 
1996, by virtue of the ICC Termination Act of 1995, Pub. L. 104-88, 
109 Stat. 803.)
---------------------------------------------------------------------------

    In view of the foregoing considerations, the Commission has 
determined not to pursue a voluntary association approach for the 
purposes of its Pub. L. 89-777 program.
2. Self-Insurance
    The self-insurance requirements currently in place were established 
by the Commission's Final Rule in Docket No. 92-50, which became 
effective February 1, 1993. Previously, self-insurers needed to 
demonstrate net worth and working capital each equal to 110% of the 
PVO's UPR--the standard the 1994 Inquiry suggested that the Commission 
might restore.
    Current self-insurance standards provide that PVOs demonstrating a 
minimum of five years' operation in U.S. trades, with a satisfactory 
explanation of any claims for nonperformance of transportation, need 
only demonstrate net worth equal to 110% of their UPR to qualify for 
self-insurance. Self-insurers are not, however, entitled to the sliding 
scale UPR coverage requirements that had been adopted in the Final Rule 
in Docket No. 92-19,23 and qualifying assets still must be located 
in the U.S.
---------------------------------------------------------------------------

    \23\ Please refer to footnote 5, infra.
---------------------------------------------------------------------------

    The comments on the 1994 Inquiry urge the Commission not to repeal 
self-insurance for private operators. AMCV has offered a rationale why 
the Commission should neither terminate self-insurance for commercial 
PVOs, as proposed in the NPR, nor implement the 1994 Inquiry's 
suggested restoration of the Commission's former and more rigorous 
standard.
    Foreign-flag operators take a different tack, urging repeal of the 
U.S.-based asset requirement. Carnival proposes a standard that would 
not only repeal the U.S.-based asset requirement but also provide for 
self-insurance qualification for PVOs which either (1) have earned 
investment grade ratings by the bonding rating agencies; or (2) meet 
both (a) a three times tangible net worth test and (b) a liquidity test 
(cash, short term investments and undrawn lines of credit equal to at 
least 100% UPR).
    The foreign-flag operators, and Carnival in particular, seek a 
system that appears to be well suited for assessing a company's 
investment risk. However, Carnival's ``investment risk'' test may not 
be appropriate for a statute that contemplates indemnification of 
passengers in the event a carrier does not fulfill its obligations.
    In this regard, we note that Carnival's proposed test is 
conditioned upon the Commission removing the U.S.-based asset 
requirement. We believe this requirement is critical to the self 
insurance standard. Unless passengers have the ability to attach a 
defaulting carrier's assets, self insurance under any standard is 
problematic.24 As the Commission remarked in its Final Rule in 
Docket 92-50:

    \24\ Although Carnival has proposed that self-insuring PVOs 
assent to U.S. jurisdiction in disputes with passengers over UPR and 
that PVOs designate agents for service of process, we do not believe 
that these measures would be sufficient for a passenger to attach a 
carrier's foreign-based assets. Moreover, this would not add 
anything new because section 3 UPR is already protected by U.S. Law 
(Pub. L. 89-777) and all section 3 applicants are required to 
appoint agents for service of process before they are certificated. 
Also, the Commission's concern is not limited to disputes between 
viable PVOs and passengers over UPR; rather, the Commission is 
concerned with a failing PVO's ability to indemnify passengers for 
nonperformance, which goes well beyond U.S. jurisdiction over simple 
disputes.
---------------------------------------------------------------------------

    Although AHC and ICCL have requested the Commission to relax the 
requirement that the assets used to qualify as a self-insurer be 
physically located in the United States, the final rule herein 
continues existing requirements for the location of those assets. 
The Commission remains concerned that passengers may not have the 
ability or resources to pursue foreign-domiciled assets, and that 
such efforts would not be cost-effective in the majority of 
instances.* Moreover, as noted in the NPR, ``self-insurance presents 
a greater risk of loss to the travelling public than do other forms 
of coverage that are backed by independent interests holding sums of 
money for the protection of the public.''

Qualification Standards, 57 FR 47830 (October 20, 1992), Final Rule, 
57 FR 62480 (December 31, 1992).
---------------------------------------------------------------------------

    On the other hand, AMCV's comments appear to provide a basis to 
ameliorate some of the concerns that originally prompted the Commission 
to propose withdrawing self-insurance as

[[Page 33063]]

an available option for commercial PVOs.25 AMCV explains that 
traditional maritime liens and preferred mortgages, which have priority 
over passenger claims, are first deducted prior to calculating net 
worth under the existing rule; therefore, the resultant net worth used 
to qualify for section 3 self-insurance has already accounted for those 
liabilities.26
---------------------------------------------------------------------------

    \25\ AMCV also suggested that the widespread use of credit cards 
and the protection offered by the Truth-in-Lending Laws and private 
travel insurance programs, act to buttress any shortfalls in the 
Commission's self-insurance options. While this may or may not be 
true, the Commission nevertheless has an independent obligation to 
make certain that PVOs have established their financial 
responsibility to indemnify passengers for nonperformance of 
transportation. Accordingly, we do not believe that the statutes or 
programs referred to by AMCV obviate the need for the Commission to 
fulfill its statutory responsibilities.
    \26\ Although AMCV may have addressed some of the Commission's 
concerns with respect to self-insurance, it did not address other 
potential payables that may have priority over passengers claims, 
e.g., employee salaries, benefits, legal fees. However, the proposed 
restoration of the former working capital standard, together with 
the additional requirement suggested below, should suffice to 
establish the requisite level of financial responsibility.
---------------------------------------------------------------------------

    After further consideration, the Commission has determined to 
withdraw its proposal to discontinue self-insurance for commercial 
operators. Instead, the Commission proposes to continue self-insurance, 
but with revised criteria. To this end, the proposed rule herein would 
revise Part 540 to permit PVOs other than state or Federal 
instrumentalities to qualify for a Performance Certificate using U.S.-
based net worth and working capital each equal to or greater than their 
outstanding UPR, plus an additional cushion of 25% of UPR backed by a 
traditional guaranty, surety bond, insurance or escrow account. Such an 
approach would permit commercial operators, like AMCV, to continue to 
use the self-insurance option currently set forth in the Commission's 
rules, provided they also can evidence working capital equal to their 
outstanding UPR and can acquire a guaranty, surety bond, insurance or 
escrow account for 25% of their outstanding UPR.
3. Liens, Mortgages and Other Security Instruments
    This aspect of the 1994 Inquiry drew no support in the comments. In 
fact, commenters provided sound reasons why it should not be pursued 
further. Accordingly, the Commission intends to take no further action 
with respect to this option.

III. Discussion

    Notwithstanding the industry's general position that changes are 
not necessary, the Commission's concern about the adequacy of its 
financial responsibility standards has, if anything, increased. 
Subsequent to the close of the comment period in the 1994 Inquiry, 
three additional passenger vessel operators have sought protection 
under the Bankruptcy Code:

--In late December 1994, Gold Star Cruises ceased operations and filed 
for Chapter 7 bankruptcy.
--As of October 29, 1995, Regency Cruises ceased operations. It 
subsequently filed for Chapter 11 protection on November 7, 1995.
--On October 30, 1995, Palm Beach Cruises filed for Chapter 11 
protection to reorganize.

In each of these cases, there appear to be sufficient funds set aside 
to indemnify passengers scheduled to embark at U.S. ports. At the same 
time, it should be noted that there was some concern regarding Regency 
because its unearned passenger revenue had from time to time exceeded 
the current ceiling; however, Regency ceased operations at a time when 
its unearned passenger revenue was below the ceiling.
    Accordingly, in light of the foregoing the Commission believes that 
it must now proceed to revise its coverage requirements to narrow the 
gap between coverage and UPR as a means of enhancing protection for the 
public.

A. Revised Coverage Requirements

1. Coverage Levels
    As aforementioned, the Commission remains concerned about the 
increased exposure to risk of the travelling public's deposits and 
prepaid fares in the event that a PVO holding UPR levels above the 
current ceiling defaults, possibly leaving passengers unprotected and 
subject to financial losses. The Commission therefore proposes to 
remove the $15 million ceiling in 46 CFR 540.9(j). Adjustments will 
also be proposed to the sliding scale and eligibility requirements 
currently set forth in 540.5(e). The Commission also proposes to 
introduce a new sliding scale coverage table that would apply to all 
operators.
    a. Reduced Coverage Scale. The revised sliding scale in 46 CFR 
540.5(e) would continue to be available to passenger vessel operators 
that can provide evidence of at least five years' operation in United 
States trades, with a satisfactory explanation of any claims for 
nonperformance of transportation. Operators opting to use this reduced 
coverage sliding scale would, in addition, have to demonstrate that 
their debt is rated ``Aa'' or better by Moody's Investors Service. For 
those who qualify, this reduced coverage sliding scale would require 
100 percent coverage for UPR up to $15 million and, when fully phased 
in, 60 percent coverage for UPR between $15 and $50 million; 20 percent 
coverage for amounts between $50 and $100 million; and 10 percent for 
amounts over $100 million. The reduced coverage sliding scale would be 
phased in over a 3-year period to minimize the impact of the new 
coverage requirements.27
---------------------------------------------------------------------------

    \27\ The proposed reduced coverage sliding scale would require 
100 percent coverage for a PVO's first $15 million in UPR and phase 
in this revised coverage requirement in three increments:
    First, effective March 1, 1997, it would require 60 percent 
coverage for UPR between $15 and $25 million; 20 percent coverage 
for amounts between $25 and $50 million and 10 percent coverage for 
amounts over $50 million.
    Second, effective March 1, 1998, it would require 60 percent 
coverage for UPR between $15 and $35 million; 20 percent coverage 
for amounts between $35 and $75 million and 10 percent coverage for 
amounts over $75 million.
    Finally, effective March 1, 1999, it would require 60 percent 
coverage for UPR between $15 and $50 million; 20 percent coverage 
for amounts between $50 and $100 million; and 10 percent coverage 
for amounts over $100 million.
---------------------------------------------------------------------------

    The Commission believes that this approach would give more weight 
to third-party, marketplace assessments of a PVO's financial strength 
in determining its section 3 risk. Moreover, this approach relies, 
albeit indirectly, upon foreign-based assets as urged by foreign-flag 
PVOs in connection with the self-insurance standards.
    b. Standard Coverage Scale. The new standard coverage sliding scale 
would be available to all PVOs, regardless of the extent of their 
operational experience, their financial standing or their explanations 
for instances of nonperformance. When fully phased in, the standard 
coverage sliding scale would ultimately require 100 percent coverage 
for UPR up to $50 million; 75 percent coverage for amounts between $50 
and $100 million; and 25 percent coverage for amounts over $100 
million. The standard coverage sliding scale would be phased in over a 
3-year period to minimize the impact of the new coverage 
requirements.28
---------------------------------------------------------------------------

    \28\ The proposed rule would phase in this revised coverage 
requirement in three increments:
    First, effective March 1, 1997, it would require 100 percent 
coverage for UPR up to $25 million; 75 percent coverage for amounts 
between $25 and $35 million; and 25 percent coverage for amounts 
over $35 million.
    Second, effective March 1, 1998, it would require 100 percent 
coverage for UPR up to $35 million; 75 percent coverage for amounts 
between $35 and $50 million; and 25 percent coverage for amounts 
over $50 million.
    Finally, effective March 1, 1999, it would require 100 percent 
coverage for UPR up to $50 million; 75 percent coverage for amounts 
between $50 and $100 million; and 25 percent coverage for amounts 
over $100 million.

---------------------------------------------------------------------------

[[Page 33064]]

2. Self-Insurance
    The Commission has determined to propose the restoration of self-
insurance for private PVOs that can demonstrate both U.S.-based net 
worth and working capital each equal to their outstanding UPR,29 
with an additional cushion of 25% of UPR backed by a traditional 
guaranty, surety bond, insurance or escrow account.
---------------------------------------------------------------------------

    \29\ The Commission also proposes restoring the procedure to 
waive, for good cause shown, the requirement as to the amount of 
working capital appearing in the former Sec. 540.5(d).
---------------------------------------------------------------------------

3. Effective Date
    While the Commission wishes to revise section 3, Public Law 89-777, 
requirements at the earliest practicable date, it does not wish to do 
so in a manner that unnecessarily disrupts the passenger vessel 
industry. In this connection, the Commission acknowledges the 
widespread practice of P&I Clubs to require members to fully 
countersecure their section 3, Public Law 89-777, guaranties as well as 
the P&I Club practice of renewing coverages during February of each 
year. Therefore, the proposed rule herein would phase in the revised 
coverage requirements over a 3-year period beginning March 1, 1997, and 
ending March 1, 1999.

B. Revision of Part 540's Escrow Agreement Guideline

    In a recent bankruptcy involving a PVO that had used an escrow 
agreement to meet its section 3, Public Law 89-777 financial 
responsibility requirements, the question arose as to whether the 
escrow's assets should be considered debtor's property. The escrow 
agreement at issue contained language that the Commission has changed 
in other escrow agreements it has since approved so as to address this 
issue. Therefore, we are proposing a change to paragraph 12 to require 
language that makes clear that escrow funds are not debtor's property 
and should be made available to passengers.

C. Filing Deadline

    Section 540.4(b) requires that an application for a Certificate 
(Performance) shall be filed at least 60 days in advance of the 
arranging, offering, advertising, or providing of any water 
transportation or tickets in connection therewith. Late filing of the 
application is permitted only for good cause shown. With the growth of 
the passenger vessel industry over the years since this requirement was 
first promulgated, together with the industry's increasing reliance on 
complex financial responsibility proposals requiring case-by-case 
assessment by the Commission, a 60-day period can be insufficient. 
Accordingly, this is being changed to a 90-day period, absent good 
cause shown.
    The Federal Maritime Commission certifies, pursuant to section 
605(b) of the Regulatory Flexibility Act, 5 U.S.C. 605(b), that this 
proposed rule, if adopted, will not have a significant economic impact 
on a substantial number of small entities, including small businesses, 
small organizational units, and small governmental organizations. The 
passenger vessel operators impacted by the rule are generally not small 
businesses.
    The collection of information requirements contained in this rule 
have been submitted to the Office of Management and Budget for review 
under section 3507 of the Paperwork Reduction Act of 1995. The annual 
public reporting and recordkeeping burden for this collection of 
information is estimated to average 14.91 hours per response. Burden 
means the total time, effort, or financial resources expended by 
persons to generate, maintain, retain, or disclose or provide 
information to or for a Federal agency. This includes the time needed 
to review instructions; develop, acquire, install, and utilize 
technology and systems for the purposes of collecting, validating, and 
verifying information, processing and maintaining information, and 
disclosing and providing information; adjust the existing ways to 
comply with any previously applicable instructions and requirements; 
train personnel to be able to respond to a collection of information; 
search data sources; complete and review the collection of information; 
and transmit or otherwise disclose the information.
    Written comments are invited on: (a) Whether the proposed 
collection of information is necessary for the proper performance of 
the functions of the agency, including whether the information shall 
have practical utility; (b) the accuracy of the agency's estimates of

The Commission, for good cause shown, may consider a time period other 
than the previous 2-fiscal-year period requirement in this section or 
other methods acceptable to the Commission to determine the amount of 
coverage required. Evidence of adequate financial responsibility for 
the purposes of this subpart may be established by one or a combination 
(including Sec. 540.6 Surety Bonds) of the following methods:
* * * * *
    (d) Filing with the Commission for qualification as a self-insurer 
such evidence acceptable to the Commission as will demonstrate 
continued and stable passenger operations over an extended period of 
time in the foreign or domestic trade of the United States. In 
addition, applicants other than state or Federal entities must 
demonstrate financial responsibility by maintenance of working capital 
and net worth, each in an amount no less than 100 percent of the 
unearned passenger revenue of the applicant on the date within the 2 
fiscal years immediately prior to the filing of the application which 
reflects the greatest amount of unearned passenger revenue. The 
Commission will take into consideration all current contractual 
requirements with respect to the maintenance of such working capital 
and/or net worth to which the applicant is bound. Evidence must be 
submitted that the working capital and net worth required above are 
physically located in the United States. This evidence of financial 
responsibility shall be supplemented by evidence demonstrating that 
twenty-five percent of applicant's unearned passenger revenue is 
covered by one or a combination of the following: evidence of insurance 
pursuant to Sec. 540.5(a); evidence of an escrow account pursuant to 
Sec. 540.5(b); a guaranty pursuant to Sec. 540.5(c); or a surety bond 
pursuant to Sec. 540.6. This evidence of financial responsibility shall 
be supported by and be subject to the following which are to be 
submitted on a continuing basis for each year or portion thereof while 
the Certificate (Performance) is in effect;
* * * * *
    (6) A list filed semiannually of all contractual requirements or 
other encumbrances (and to whom the applicant is bound in this regard) 
relating to the maintenance of working capital and net worth;
* * * * *
    (e) (1) The following schedule may be applied to determine the 
minimum coverage required for indemnification of passengers in the 
event of nonperformance of water transportation for those operators who 
have not elected to qualify by an escrow account or self-insurance; and 
can provide evidence (in the form of an affidavit by the operator's 
Chief Executive Officer or other responsible corporate officer) that 
applicant's debt is rated by Moody's Investors Service at Aa or higher; 
and of a minimum of five years of operation in United States trades 
with a satisfactory explanation of any claims for nonperformance of 
transportation.

Limes Grown in Florida and Imported Limes; Reopening of Comment 
Period To File Written Comments to the Change in Regulatory Period

AGENCY: Agricultural Marketing Service, USDA.

ACTION: Reopening of the comment period to file written comments to the 
proposed rule.

-----------------------------------------------------------------------

SUMMARY: Notice is hereby given that the time period for filing written 
comments on the proposed changes to the regulatory period currently 
prescribed under the lime marketing order and the lime import 
regulations is reopened until July 8, 1996.

DATES: Comments must be received by July 8, 1996.

ADDRESSES: Interested persons are invited to submit written comments 
concerning this proposal. Comments must be sent in triplicate to the 
Docket Clerk, Fruit and Vegetable Division, AMS, USDA, room 2525-S, 
P.O. Box 96456, Washington, DC 20090-6456, FAX Number (202) 720-5698. 
All comments should reference the docket number and the date and page 
number of this issue of the Federal Register and will be available for 
public inspection in the Office of the Docket Clerk during regular 
business hours.

FOR FURTHER INFORMATION CONTACT: Britthany Beadle, Marketing Order

Branch, F&V, AMS, USDA, P.O. Box 2276, Winter Haven, Florida 33883; 
telephone: (941) 299-4770.

SUPPLEMENTARY INFORMATION: A proposed rule was issued on May 2, 1996, 
and published in the Federal Register (61 FR 20754). The proposed rule 
would modify language in both the domestic and import regulations to 
change the regulatory period to January 1 through May 31, from its 
current continuous, year round, implementation. A 30-day comment period 
was provided for interested persons to respond to the proposed rule. 
The comment period ended June 7, 1996. One comment was received.
    The Department of Agriculture (Department) has received a request 
from Gail A. Knodel, Manager of the Florida Lime Administrative 
Committee, asking that additional time be provided for interested 
persons to analyze the proposed rule. Manager Knodel stated that the 
proposal is a major change in the industry. Reopening the comment 
period to July 8, 1996, would allow interested person more time to 
review the proposed rule and address their concerns.
    This delay should not substantially add to the time required to 
complete this action. Accordingly, the period in which to file written 
comments is reopened until July 8, 1996. This notice is issued pursuant 
to the Agricultural Marketing Agreement Act of 1937.

    Authority: 7 U.S.C. 601-674.

Regulation of Fuels and Fuel Additives: Controls Applicable to 
Gasoline Retailers and Wholesale Purchaser-Consumers; 10 Gallon Per 
Minute Fuel Dispensing Limit Requirement Implementation

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: On January 20, 1993 EPA finalized a requirement limiting 
vehicle service station fuel dispensing rates to 10 gallons per minute 
(gpm) maximum, beginning January 1, 1996 for retailers and wholesale 
purchaser-consumers handling over 10,000 gallons of fuel per month (55 
FR 16002, March 24, 1993). In 1995, various groups in the petroleum 
industry requested that EPA delay the January 1, 1996 deadline, due 
mainly to the lack of available retrofit parts needed for compliance 
with the 10gpm requirement. EPA is proposing to delay the 
implementation date of the 10gpm requirement from January 1, 1996 until 
July 1, 1996. In addition, EPA is proposing regulation changes to 
clarify that the hardware/software for controlling the fuel dispensing 
rate may be located anywhere in the pump/dispenser system and that 
refueling facilities are exempt from the 10gpm requirement if used 
exclusively to refuel heavy-duty vehicles, boats or airplanes.
    Because the rule revision is not expected to receive any adverse 
comments, the revision is also being issued as a direct final rule in 
the Final Rules section of this Federal Register.

DATES: Comments on the regulations proposed by this action must be 
received on or before July 26, 1996.

ADDRESSES: Materials relevant to the initial final rule, and today's 
action are available for inspection in Public Dockets A-89-18 and A-95-
53 at Air Docket Section, U.S. Environmental Protection Agency, EPA Air 
Docket Section (6102), First Floor, Waterside Mall, Room M-1500, 401 M 
Street S.W., Washington, D.C. 20460 (telephone 202-260-7549, fax 202-
260-4400) between the hours of 8 a.m. and 5:30 p.m. A reasonable fee 
may be charged by EPA for copying docket material.
    All written comments must be identified with the appropriate docket 
number (Docket No. A-95-53) and must be submitted in duplicate to the 
address listed above, with a complimentary

    This table is not intended to be exhaustive, but rather provides a 
guide for readers regarding entities likely to be regulated by this 
action. This table lists the types of entities that EPA is now aware 
could potentially be regulated by this action. Other types of entities 
not listed in the table could also be regulated. To determine whether 
your facility is regulated by this action, you should carefully examine 
the criteria contained in Sec. 80.22(j) of title 40 of the Code of 
Federal Regulations, as modified by today's action. If you have 
questions regarding the applicability of this action to a particular 
entity, consult one of the persons listed in the preceding FOR FURTHER 
INFORMATION CONTACT section.
    If no adverse comments are timely received, no further activity is 
contemplated in relation to this proposed rule and the direct final 
rule in the Final Rules section of this Federal Register will 
automatically go into effect on the date specified in that rule. If 
adverse comments are timely received on the direct final rule, the rule 
will be withdrawn and all public comment received on it will be 
addressed in a subsequent final rule based on this proposed rule. 
Because the Agency will not institute a second comment period on this 
proposed rule, any parties interested in commenting should do so during 
this comment period.
    For further supplemental information, the detailed rationale, and 
the rule revisions, see the information provided in the direct final 
rule in the Final Rules section of this Federal Register.

Proposed Test Rule for Hazardous Air Pollutants

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: EPA is proposing a test rule under section 4(a) of the Toxic 
Substances Control Act (TSCA) to require manufacturers and processors 
of 21 hazardous air pollutants (HAPs) (biphenyl, carbonyl sulfide, 
chlorine, chlorobenzene, chloroprene, cresols [3 isomers], 
diethanolamine, ethylbenzene, ethylene dichloride, ethylene glycol, 
hydrochloric acid, hydrogen fluoride, maleic anhydride, methyl isobutyl 
ketone, methyl methacrylate, naphthalene, phenol, phthalic anhydride, 
1,2,4-trichlorobenzene, 1,1,2-trichloroethane, and vinylidene chloride) 
to test these substances for certain health effects. EPA is also 
soliciting proposals for enforceable consent agreements (ECAs) 
regarding the performance of pharmacokinetics studies which would 
permit extrapolation from oral data to predict risk from inhalation 
exposure. EPA is also withdrawing the oncogenicity testing proposed for 
vinylidene chloride on August 12, 1986 (51 FR 28840).
DATES: Written comments on this proposed HAPs test rule must be

    This table is not intended to be exhaustive, but, rather, provides 
a guide for readers regarding entities likely to be regulated by this 
action. This table lists the types of persons of which EPA is now aware 
that potentially could be regulated by this action. To determine 
whether you would be subject to this rule, you should examine Unit 
IV.F. of the preamble entitled ``Persons Required to Test'' and consult 
40 CFR 790.42.

I. Statutory Authority

    This notice proposes a test rule under section 4 of the Toxic 
Substances Control Act (TSCA), 15 U.S.C. 2603 et seq., that would 
require certain health effects testing for 21 chemical substances 
listed as hazardous air pollutants (HAPs) in section 112 of the Clean 
Air Act (CAA), 42 U.S.C. 7412.
    Section 2(b)(1) of TSCA, 15 U.S.C. 2601(b)(1), states that it is 
the policy of the United States that ``adequate data should be 
developed with respect to the effect of chemical substances and 
mixtures on health and the environment and that the development of such 
data should be the responsibility of those who manufacture and those 
who process such chemical substances and mixtures[.]'' To implement 
this policy, section 4(a) of TSCA authorizes EPA to require by rule 
that manufacturers and processors of chemical substances conduct 
testing if the Administrator finds that:

[[Page 33179]]

    (1)(A)(i) the manufacture, distribution in commerce, processing, 
use, or disposal of a chemical substance or mixture, or that any 
combination of such activities, may present an unreasonable risk of 
injury to health or the environment, [or]
    (1)(B)(i) a chemical substance or mixture is or will be produced 
in substantial quantities, and (I) it enters or may reasonably be 
anticipated to enter the environment in substantial quantities or 
(II) there is or may be significant or substantial human exposure to 
such substance or mixture, [and]
    (1)(A)(ii) and (1)(B)(ii) there are insufficient data and 
experience upon which the effects of the manufacture, distribution 
in commerce, processing, use, or disposal of such substance or 
mixture or of any combination of such activities on health or the 
environment can reasonably be determined or predicted, and
    (1)(A)(iii) and (1)(B)(iii) testing of such substance or mixture 
with respect to such effects is necessary to develop such data[.]

    Thus once the Administrator has made a finding under TSCA section 
4(a)(1)(A)(i) that a chemical substance may present an unreasonable 
risk of injury to health or the environment or a finding under section 
4(a)(1)(B)(i) that a chemical substance is or will be produced in 
substantial quantities and either it may enter the environment in 
substantial quantities or there may be significant substantial human 
exposure to the chemical substance, EPA may require any type of health 
effects or environmental testing necessary to address unanswered 
questions about the effects of the chemical substance. EPA need not 
limit the scope of testing required to the factual basis for the 
section 4(a)(1)(A)(i) or (B)(i) findings as long as EPA finds that data 
relevant to a determination of whether a substance does or does not 
present an unreasonable risk of injury to health or the environment are 
insufficient and that testing is necessary to develop such data. This 
concept is explained in more detail in EPA's statement of policy for 
making findings under TSCA section 4(a)(1)(B) (frequently described as 
the ``B policy'') in the Federal Register of May 14, 1993 (58 FR 
28736). Unit V of this preamble also describes the B policy. Moreover, 
EPA need not limit the scope of the requirement only to testing needed 
to support regulatory action under TSCA. For further discussion of 
findings under TSCA section 4, see Unit V of this preamble and the 
document entitled ``TSCA Section 4 Findings for 21 Hazardous Air 
Pollutants'' in the record for this rulemaking.
    In this proposed rule, EPA intends to use its TSCA section 4 
authority to obtain data necessary to implement section 112 of the CAA, 
which provides a detailed strategy for the assessment and management of 
HAPs. EPA has used this broad TSCA section 4 authority in the past to 
support regulatory programs requiring health and environmental effects 
testing data. See, e.g., final test rule for the Office of Solid Waste 
chemicals (53 FR 22300, June 15, 1988); final test rule for the Office 
of Water Chemicals (58 FR 59667, November 10, 1993). Additional users 
of information collected under this test rule would include other 
federal agencies (e.g. the Agency for Toxic Substances and Disease 
Registry (ATSDR), the National Institute for Occupational Safety and 
Health (NIOSH), the Occupational Safety and Health Administration 
(OSHA), the Consumer Product Safety Commission (CPSC), other program 
areas within EPA (such as the hazardous waste program under the 
Resource Conservation and Recovery Act (RCRA), the Toxics Release 
Inventory (TRI), the Integrated Risk Information System database 
(IRIS), and the Office of Pesticide Programs (OPP)), and state and 
local environmental authorities.
    Supporting statutory authority for this proposed rule is provided 
by section 112(b)(4) of the CAA, 42 U.S.C. 7412(b)(4), which 
specifically authorizes EPA to use any authority available to EPA to 
obtain the information needed to make determinations regarding the 
addition or deletion of substances to the statutory list of HAPs in CAA 
section 112(b)(1), 42 U.S.C. 7412(b)(1). If the data collected under 
this proposed test rule show that a chemical substance is not a concern 
to human health, this information would be helpful in making decisions 
concerning delisting the substance from the Clean Air Act HAPs list.
    This toxicity testing program is also intended to fulfill in part 
EPA's statutory obligation under section 103(d) of the CAA, 42 U.S.C. 
7403(d), to conduct a research program on the health effects of HAPs. 
This preamble, along with the supporting material in the record, 
provides information that would be used in the research program under 
CAA section 103(d) for the HAPs proposed for testing in this rule.

II. Uses for Data

    EPA will primarily use the data proposed to be collected under this 
rule to implement several provisions of section 112 of the CAA, 
including the determination of residual risk (see below), the 
estimation of the risks associated with accidental releases of 
chemicals, and determinations whether or not substances should be 
removed from the CAA section 112(b)(1) list of hazardous air pollutants 
(delisting). The acute toxicity test data and developmental toxicity 
test data will be useful in judging risks from accidental release. The 
term ``accidential release'' is used broadly in this proposal to 
include any short-term, relatively high-level chemical exposure lasting 
from several minutes to several hours. Such a release may result from 
various causes, including spills, transportation accidents, process-
upset conditions, or short bursts during charging of reaction vessels. 
All data are relevant to delisting decisions and all non-acute data 
will be used by EPA in meeting its statutory obligation under CAA 
section 112(f), 42 U.S.C. 7412(f), to assess the risk remaining (i.e. 
residual risk) after the imposition of technology-based emission 
standards (maximum achievable control technology or MACT standards) 
required by CAA section 112(d), 42 U.S.C. 7412(d). Section 112(e) of 
the CAA, 42 U.S.C. 7412(e), directs EPA to promulgate these standards 
between 1992 and 2000.
    Section 112(f)(1) of the CAA requires EPA to submit, by November 
1996, a report to Congress that will describe the methods for assessing 
the risk remaining after the application of technology-based standards 
under section 112(d) of the CAA. These methods will be used to assess 
any residual risk for persons exposed to MACT-regulated emissions. The 
assessment will include an analysis of both cancer and noncancer 
endpoints. Data generated by the proposed test rule would be used in 
the analysis to determine the nature and magnitude of any residual 
risk.
    Within eight years after the promulgation of technology-based 
standards, EPA may need to set additional standards (``post-MACT 
standards'') to protect public health with an ample margin of safety. 
Section 112(f)(2) of the CAA specifies that if MACT standards have not 
reduced lifetime cancer risk to the individual most exposed to known or 
suspected carcinogenic emissions from a source to a level of less than 
1 in a million (1 x 10-6), health-based emission standards must be 
promulgated in order to protect public health with an ample margin of 
safety. EPA, therefore, would use data obtained under this proposed 
rule to determine whether health-based post-MACT standards are needed 
and, if they are needed, to assist in establishing the appropriate 
level of these standards.
    For noncancer health effects, EPA applies an appropriate 
mathematical model to toxicity data in order to determine the benchmark 
dose level. The benchmark dose or concentration (BMD/C) is defined as 
the statistical

[[Page 33180]]

lower confidence limit on the dose estimated to produce a predetermined 
level of change in response (the benchmark response--BMR) relative to 
controls. If the data are not amenable to modeling, a no-observed-
adverse-effect level (NOAEL) or a lowest-observed-adverse-effect level 
(LOAEL) may be obtained from an evaluation of the toxicity database. 
``Uncertainty factors'' are then applied to these levels to account for 
uncertainties in deriving a dose-response estimate for human exposure 
(reference concentration (RfC)) from experimental data. An RfC is 
defined as ``an estimate (with uncertainty perhaps spanning an order of 
magnitude) of a continuous inhalation exposure to the human population 
(including sensitive subgroups) that is likely to be without 
appreciable risk of deleterious noncancer health effects during the 
lifetime'' (Ref. 1).
    Uncertainties due to the extrapolation of effects data between 
species and for individual susceptibility within a species are 
accounted for by uncertainty factors. Because RfCs are intended to 
characterize risk for lifetime exposures, an uncertainty factor may be 
applied if the effects data are extrapolated from a subchronic study. 
An additional uncertainty factor is applied if a LOAEL is used to 
derive the RfC rather than a NOAEL. To provide an accurate 
characterization of lifetime risk, the database for a chemical should 
be comprehensive and, in principle, should address all potential 
endpoints at critical life stages. Therefore, an uncertainty factor 
also may be applied if data for appropriate endpoints are not 
available. Thus while each uncertainty factor may range up to 10, the 
composite factor used to derive an RfC for a chemical with a limited 
database may be on the order of up to 3,000 for inhalation studies and 
up to 10,000 for oral studies. Five uncertainty factors are never 
applied at the same time (i.e. no composite uncertainty factor can be 
greater than 10,000) because such derivations are considered too 
inaccurate to be used.
    Large composite uncertainty factors result in lower RfCs (higher 
risk estimates) than do smaller composite uncertainty factors. If the 
RfC is low, EPA may be required to promulgate more stringent emission 
standards. Industrial plants subject to these standards would, in turn, 
be required to meet such standards, perhaps necessitating the 
installation of more costly emission controls. Better and more complete 
health effects data, on the other hand, may permit EPA to use smaller 
composite uncertainty factors, resulting in higher RfCs and, as a 
consequence, less stringent emission standards. Thus the economic cost 
of using poor-quality health effects data to make residual risk 
determinations under CAA section 112(f) could be considerable.
    In addition, secondary--though as important--uses of the data to be 
collected under this proposed rule would be:
    (1) Helping to better inform communities and citizens of toxic 
chemical hazards in their own localities. Understanding health effects 
associated with these chemicals is integral to furthering the public's 
involvement in environmental decisionmaking, especially at the state 
and local level. To be an effective participant in this process, the 
public needs information on both the inherent toxicity (i.e., hazard) 
of a chemical and the potential sources of exposure to the chemical. 
This rule will provide valuable information on health effects related 
to the affected chemicals, and under TSCA, such health and safety data 
are available to the public. Taken together with such publicly 
available information sources such as the Toxics Release Inventory 
(TRI), which provides site-specific information on chemical releases 
into the environment, the health effects data generated under this rule 
will allow all segments of the public to better assess the risks 
associated with the releases of these chemicals. Taken as part of a 
comprehensive right-to-know program, these data will provide the basis 
for individuals, communities, governments, producers, and users to 
assess the nature and relative severity of toxicity among different 
chemicals, as well as to assess site-specific, individual chemical 
risk.
    (2) Assisting other agencies (e.g., ATSDR, NIOSH, OSHA, CPSC) in 
assessing chemical risks and in taking appropriate action within their 
programs. For example, OSHA has expressed a need for the data that will 
be acquired under the proposed rule. Fifteen of the 21 HAPS are 
candidates for OSHA's Permissible Exposure Limit (PEL) update and an 
additional 3 have no corresponding PEL. OSHA does not have authority to 
require testing, and must rely on toxicology data collected by other 
agencies for their risk assessments (Ref. 2). Establishing an ongoing 
mechanism for updating its PELs continues to be a high priority for 
OSHA. Five of the HAPs are on ATSDR's list of hazardous substances 
found at National Priorities List sites and are the subject of 
toxicological profiles. CPSC noted that 11 of the 21 substances are 
found in or are emitted by consumer products (Ref. 3).
    (3) Assisting EPA in evaluating delisting petitions received under 
the CAA and the Emergency Planning and Community Right-to-Know Act 
(EPCRA), 42 U.S.C. 1101 et seq., in making better clean-up decisions 
under the Comprehensive Environmental Response, Compensation, and 
Liability Act (CERCLA), 42 U.S.C. 9601 et seq., in assessing inert 
ingredients in pesticide products, in setting more appropriate 
standards for hazardous wastes under RCRA, and by providing support for 
chemical risk assessment activities under TSCA.
    (4) Assisting state and local permitting authorities in setting 
standards within their programs.
    (5) Supporting assessments of ``burst'' exposures (high-level 
releases of short duration), such as in the accidental release 
prevention program under section 112(r) of the CAA, 42 U.S.C. 7412(r), 
due to the inclusion of an acute testing protocol.
    Many HAPs are of broad programmatic interest, and are included in 
the Agency's Integrated Risk Assessment System (IRIS) database. Thus, a 
secondary benefit of this rule is that the health effects data 
generated by the rule may result in improvement to the data and 
increased confidence in the RfCs contained in IRIS. Improvements to the 
IRIS data can result in considerable benefits to the public since IRIS 
is publicly available and is used by a wide variety of governmental and 
non-governmental entities to assess the safety of chemicals.
    In some cases where EPA has had access to better data, the Agency 
has been able to revise standards to make them less stringent, thus 
mandating less economically costly levels of control. For example, EPA 
has revised the maximum contaminant levels (MCL) of barium (from 1 mg/L 
to 2 mg/L) and selenium (from 0.01 mg/L to 0.05 mg/L) in drinking water 
and withdrew the MCL for silver (0.05 mg/L) based on new data (Ref. 4).
    Data have also been used to remove chemical substances from lists 
of regulatory significance. Acrylic acid was removed from a list of 
``high-risk'' pollutants developed under section 112(i)(5) of the CAA, 
42 U.S.C. 7412(i)(5), for the early reductions program. The high-risk 
listing for this chemical was based on its predicted environmental 
exposure being at least 10 times larger than its RfC. Designation of 
acrylic acid as ``high risk'' had the effect of limiting the use of 
offsetting reduction of other pollutants in meeting early reduction 
goals. Recent data,

[[Page 33181]]

including those related to reproductive effects, developmental 
toxicity, and bioavailability, resulted in a decrease in the 
uncertainty factor for database deficiency by a factor of three and an 
increase in the RfC by the same amount (i.e. from 0.0003 mg/m3 to 
0.001 mg/m3). Consequently, acrylic acid no longer met the 
criteria for the high-risk list.
    Serious deficiencies exist in the current toxicity database for the 
189 HAPs listed in the CAA, in that no toxicity data exist for many 
HAPs regarding various endpoints of concern. This problem is expected 
to be especially serious because post-MACT residual risks will arise 
primarily from exposures to emissions that contain different 
combinations of HAPs in varying concentrations. In view of the large 
number of HAPs of concern and the much larger number of combinations of 
those HAPs found in the mixtures of emissions subject to residual risk 
evaluation, the toxicity database should provide consistent 
characterization of individual HAPs. Therefore, EPA is proposing to 
obtain an even, across-the-board database for the HAPs listed in this 
proposed rule.
    In its report regarding the risk assessment of HAPs, the National 
Academy of Sciences (NAS) states that ``[a]vailability of requisite 
data varies widely among the 189 [HAPs] chemicals'' (Ref. 5). According 
to this report, ``the toxicity data are incomplete on almost all 189 
chemicals'' (Ref. 5). For example, the level of carcinogenic risk for 
approximately 40% of the 189 HAPs cannot be classified under EPA's 
current cancer risk classification system (Ref. 6). Moreover, while 
quantitative estimates exist for 70% of the HAPs that have been 
classified for cancer risk, about 70% of these estimates are based only 
on oral data and thus may not reliably characterize the potential risk 
encountered through inhalation exposure.
    In evaluating 124 of the 189 HAPs for noncancer risk, EPA found 
that the databases for about 62% of the 124 HAPs were not adequate for 
deriving an RfC (Ref. 7). Even for those HAPs that have an RfC, the 
level of uncertainty associated with such figures is often high. EPA 
would use data from the testing proposed in this rule to identify the 
critical health risks posed by many individual HAPs and to characterize 
the adverse impact posed by exposure to mixtures of HAPs. EPA 
anticipates that the test data produced in response to this rule would 
provide the consistent database that the National Academy says is 
lacking at this time.

III. Testing Approach and Selection of Chemical Substances for This 
Proposed Rule

A. Testing Approach Chosen by EPA

    With respect to EPA's responsibilities for meeting the requirements 
under section 112 of the CAA, the central question is: How broad and 
deep a data set should EPA require on each HAP?
    Regarding specific endpoints and routes of exposure, CAA section 
112(b)(2), 42 U.S.C. 7412(b)(2), indicates that Congress intended that 
adverse effects from any endpoint by any route of exposure be taken 
into account in listing substances as HAPs. According to this 
subsection, substances added to the Clean Air Act HAPs list shall 
include:

    * * * pollutants which present, or may present, through 
inhalation or other routes of exposure, a threat of adverse human 
health effects (including, but not limited to, substances which are 
known to be, or may reasonably be anticipated to be, carcinogenic, 
mutagenic, teratogenic, neurotoxic, which cause reproductive 
dysfunction, or which are acutely or chronically toxic) * * * .

    Thus the CAA indicates that Congress was very concerned about the 
wide variety of health risks attributable to HAPs and intended that 
data necessary for characterizing both cancer and noncancer health 
risks from exposure to HAPs be developed.
    Faced with a broad range of options and little specific guidance 
from Congress, EPA decided that some provision should be made for 
evaluating the health effects endpoints listed in the CAA, including 
respiratory tract toxicity, systemic effects, reproductive toxicity, 
developmental toxicity, genotoxicity, neurotoxicity, and 
carcinogenicity. EPA's objective was to select endpoints representing 
serious health effects that could occur as a result of exposure to 
HAPs. Each endpoint represents a health effect of concern arising from 
one or more of the following exposures--local concentrations (e.g., 
hotspots and plumes), area-wide sources, or accidental releases of 
HAPs.
    EPA believes that it is critical to evaluate the respiratory tract 
thoroughly in addition to examining extra-respiratory effects (i.e., 
systemic toxicity) because inhalation is an important exposure route of 
concern. Carcinogenicity testing is significant because cancer is a 
serious health effect that may be caused by long-term, low-level 
exposure to toxic substances. Developmental toxicity addresses the 
potential of chemical substances to interfere adversely with human 
development (i.e., to cause death, structural abnormalities, growth 
alterations, and/or functional deficits in the immature organism that 
may be more sensitive than the adult to many chemical substances). 
Reproductive testing is designed to assess the effects of an 
environmental agent on male and female fertility and general 
reproductive function to humans exposed prenatally as well as 
postnatally. There is general consensus among toxicologists regarding 
the assessment of cancer and reproductive and developmental effects, 
and further explanation can be found in EPA's risk assessment 
guidelines (Guidelines for Carcinogen Risk Assessment (51 FR 33992, 
September 24, 1986); Guidelines for Developmental Toxicity Risk 
Assessment (56 FR 63798, December 5, 1991); Guidelines for Reproductive 
Toxicity Risk Assessment (Pub. No. EPA/600/AP-94/001, February 1994). 
Finally, certain aspects of the neurotoxicity and immunotoxicity 
testing required in this proposed rule warrant more explanation, which 
is provided below. EPA recently published a proposed revision of the 
1986 Guidelines for Carcinogen Risk Assessment (see ``Proposed 
Guidelines for Carcinogen Risk Assessment'' at 61 FR 17960, April 23, 
1996 (FRL-5460-3)).
    Neurotoxicity resulting from chemical exposure can affect an 
organism in many ways, causing, for example, functional and structural 
deficits as well as behavioral effects. To assess neurotoxicity, EPA is 
proposing a screening-level battery, consisting of the functional 
observational battery and motoractivity and neuropathology tests. At 
this time, EPA is not proposing to require additional, more specialized 
testing for cognitive functions such as learning, memory, and 
performance.
    The interest in the potential toxic effects of chemicals on the 
immune system arises from the critical role that the immune system 
plays in maintaining health. EPA considers the field of immunotoxicity 
a promising, scientifically sound, and important area in public health 
protection. From time to time, the Agency has considered information on 
the effects of chemicals on the immune system in risk assessments. For 
example, in its draft report reassessing the effects of dioxin 
compounds on human health (Ref. 8), EPA considered the effects of 
dioxin on the immune system to serve as an important health endpoint 
that provides useful information in developing a hypothesis about 
toxicity. In the draft reassessment report, however, EPA arrived at the 
preliminary conclusion that ``the impact of dioxin and related 
compounds on the immune system and

[[Page 33182]]

implications for characterizing risks are largely unknown at this 
time.''
    This rule calls for an immunotoxicity screening test which can be 
performed as a satellite test to either a 90-day subchronic test or a 
reproductive effects test. This immunotoxicity screen will help 
identify chemicals as potential immunotoxicants. EPA is not proposing 
more comprehensive immunotoxicity testing at present because the 
application of immunotoxicity data in risk assessment has not yet 
sufficiently matured. As EPA's science policy develops and the Agency's 
use of immunotoxicity data in risk assessment increases, EPA will 
reconsider this position. Meanwhile, EPA seeks comments on its proposed 
approach of using a minimal screen and its preliminary conclusion that 
it is premature at this time to include more comprehensive 
immunotoxicity testing in this proposed HAPs test rule.
    In developing this proposed rule, EPA considered the following 
range of options to select the information needed to characterize 
health effects of concern to implement section 112 of the CAA.
    Option 1. One-species 90-day inhalation subchronic plus follow-up 
for known or suspect toxicities. Under this option, a 90-day inhalation 
subchronic test would be required, as well as testing for endpoints 
that have already been identified as existing or potential concerns, 
including cancer, by previous test results of the HAP at issue or 
structurally similar agents. A one-species 90-day inhalation test is 
considered the minimum information for the development of an RfC. The 
inhalation RfC takes into account toxic effects both for the 
respiratory tract (portal-of-entry effects) and peripheral to the 
respiratory system (extra-respiratory effects). Well-defined and well-
conducted inhalation subchronic toxicity studies--that provide for 
histopathologic evaluation of organ toxicities, including the 
respiratory tract--are considered to be reliable predictors of certain 
kinds of chronic toxicity. But such studies do not, or do not 
adequately, account for neurological, developmental and reproductive 
toxicities. An RfC based solely on a 90-day subchronic test is, thus, 
usually given a low confidence rating because some potentially 
important toxic endpoints are not characterized.
    In addition, EPA believes that for 90-day inhalation subchronic 
testing to constitute a minimally credible option, such a test should 
at least be augmented by testing for adverse health effects that are 
suggested or indicated, but not adequately characterized, by existing 
information such as short-term test data, mechanistic information or 
structure-activity relationships (SAR). Even with this modification, 
however, Option 1 still provides no test data on those health endpoints 
of concern for which no current information exists. If such testing 
were included, these effects might become critical in evaluating dose-
response relationships or in demonstrating that a standard uncertainty 
factor is inadequate or inappropriate.
    EPA thus believes that Option 1 is insufficient to meet EPA's 
mandate under section 112 of the CAA because the endpoints listed in 
section 112(b)(2) of the CAA, in particular, reproductive, 
developmental, and neurological toxicities, would be considered for 
testing only if data already exist that indicate or suggest the 
potential for these adverse effects. Moreover, this option also does 
not adequately address health risks associated with acute or accidental 
releases.
    EPA did not select Option 1 for the reasons stated above. EPA 
believes that the TSCA section 4 program adopted for testing HAPs must 
go further toward ensuring that no serious health threat exists from 
both long- and short-term exposure for endpoints of potential concern 
for which there are no existing data.
    Option 2. Option 1 plus inhalation screening for untested toxicity 
endpoints. The second option considered by EPA would require the 
incorporation of screening level testing for certain untested 
toxicities into Option 1. Like Option 1, Option 2 would include testing 
for endpoints (including cancer) that have already been identified as 
existing or potential concerns. At a minimum Option 2 would consist 
of--a 90-day subchronic inhalation study, a screening test for 
reproductive effects (i.e., a one-generation reproductive effects 
study), a subchronic inhalation neurotoxicity screening battery 
(consisting of the functional observation battery and motor activity 
and neuropathology tests), an E. coli reverse mutation assay, gene 
mutation in somatic cells in culture detection, an in vivo cytogenetics 
test (chromosomal analysis or micronucleus assay), and an 
immunotoxicity screening test. Any toxicity suggested but not 
characterized by existing studies in the toxicological literature would 
still be followed up on through more rigorous protocols.
    Although Option 2 would conserve resources while allowing for the 
testing of a broader range of endpoints, including cancer, it has 
serious shortcomings. First, a one-generation reproductive test does 
not adequately address reproductive and developmental risk. Two-
generation tests (in which animals have been exposed prenatally as well 
as postnatally, including the prepubertal period) are generally needed 
to evaluate the effects on reproduction from most exposures to chemical 
substances (Ref. 9). Two-generation tests permit the evaluation of 
delayed or latent manifestations of some toxicities, detection of 
effects absent in the first generation, and the expression and 
detection of some effects that may have a heritable basis. Because the 
standard two-generation reproductive test would not detect internal 
malformations, however, developmental toxicity testing is also needed 
for an adequate assessment of developmental risk. The Agency's policy 
is to require developmental testing in two species to adequately 
characterize the risk because of species-specific differences.
    EPA did not select Option 2 because this level of testing would not 
provide an adequate evaluation of developmental or reproductive 
toxicity. Additional follow-up testing would be required to confirm 
suggestive results obtained in screening studies and provide data 
adequate for risk assessment under this option. Such testing would 
require an additional rulemaking cycle, costing further resources and 
incurring so much delay that data would not be available to meet the 
deadlines for setting risk-based standards. Moreover, this option does 
not adequately address health risks, such as respiratory tract effects 
and neurotoxicity, associated with acute or accidental releases.
    Option 3. Option 1 plus less than chronic testing for noncancer 
endpoints of concern. In addition to the 90-day inhalation subchronic 
testing specified in Option 1, this option would add inhalation testing 
to assess reproductive effects (i.e., two-generation reproductive test) 
and developmental effects (developmental toxicity tests in two 
mammalian species). Option 3 includes an acute toxicity testing 
guideline for histopathology of the respiratory tract, kidney, and 
liver and a bronchoalveolar lavage after four hours of exposure. EPA 
believes that it is necessary to characterize the acute effects 
associated with accidental releases of HAPs. In addition, a respiratory 
sensory irritation assay is included. Acute and subchronic inhalation 
neurotoxicity screening batteries consisting of the functional 
observation battery, and motor activity and neuropathology tests would 
also be conducted. As in Option 2, first-tier tests would be required 
for mutagenicity

[[Page 33183]]

(i.e., an E. coli reverse mutation assay, gene mutation in somatic 
cells in culture detection, an in vivo cytogenetics test (chromosomal 
analysis or micronucleus assay)), as well as immunotoxicity.
    Option 3 would follow Options 1 and 2 in requiring a cancer 
bioassay where concern for cancer is indicated by short-term data, 
general toxicity data, mechanistic information or structure-activity 
relationships (SAR). Where no cancer bioassay data exist, testing two 
species in both sexes would be required. If cancer bioassay data exist 
but are found to be too uncertain for inhalation dose-response 
assessment, a modified test, such as testing of the opposite sex in two 
species, may be required (Ref. 10).
    The Option 3 level of testing would enable EPA to better 
characterize risk associated with both acute and longer-term exposures 
by providing data to identify and evaluate all the health effects 
listed under section 112 of the CAA and by providing data for dose-
response evaluation within the general time frame for risk-based 
standards under CAA section 112(f). Accordingly, EPA has selected the 
Option 3 level as its preferred option for testing under this proposed 
rule.
    Option 4. Option 3 plus chronic testing. Under this option, in the 
absence of existing adequate data, EPA would require chronic inhalation 
bioassays (for both cancer and noncancer effects) in two different 
mammalian species for each chemical substance. The balance of the test 
program would be the same as under Option 3 (developmental studies in 
two mammalian species, a two-generation reproductive study, acute and 
subchronic neurotoxicity screening batteries, first-tier mutagenicity 
tests, an immunotoxicity screening test, and acute testing). In 
general, cancer bioassay data in two species, a two-generation 
reproductive test, and a developmental study in two species are 
required to establish a high-confidence RfC. Because the RfC is 
intended to serve as a lifetime estimate, lifetime exposure studies to 
evaluate potential health endpoints at various critical life stages 
should be considered.
    To a greater degree than under other options, the broad and deep 
database that would be produced by this comprehensive testing scheme 
could help defuse complaints that EPA frequently regulates industrial 
activities without sufficient data regarding either the need for an 
appropriate level of regulation or what such a level should be. EPA has 
decided, however, that the disadvantages of choosing this option 
outweigh its considerable benefits. The extensive chronic testing 
required under Option 4 would impose a significant cost on industry. In 
addition, as compared to Option 3, the strain that choosing this option 
would place on certain resources--such as inhalation testing facilities 
and supplies of laboratory animals--would significantly diminish the 
cost-effectiveness of compiling the data. For these reasons, EPA did 
not select this option. EPA is soliciting comments on the testing 
approach to the HAPs that it has selected in this proposal.
    It should be noted that, regardless of the test option chosen, if 
adequate toxicity data on a HAP is produced by testing using a route of 
exposure other than inhalation, route-to-route extrapolation may be 
possible (see Unit IV.D. of this preamble).

B. National Academy of Sciences Approach

    In section 112(o) of the CAA, 42 U.S.C. 7412(o), Congress directed 
EPA to arrange for the NAS to review EPA's risk assessment methodology 
relevant to HAPs subject to section 112. EPA has considered the 
recommendations of the NAS regarding the assessment of risks associated 
with HAPs. The NAS recommended that EPA ``* * * compile for each of the 
189 chemicals an inventory of the existing and relevant chemical, 
toxicologic, clinical, and epidemiologic literature'' (Ref. 5). It also 
recommended that EPA ``screen the 189 chemicals for priorities for the 
assessment of health risks, identify the data gaps, and develop 
incentives to expedite generation of the needed data by other public 
agencies (such as the National Toxicology Program, the Agency for Toxic 
Substances and Disease Registry, and state agencies) and by other 
organizations (industry, academia, etc.)'' (Ref. 5). As discussed in 
Unit III.C. of this preamble, EPA agrees and has taken this approach. 
To identify testing needs and help prioritize HAPs testing, Syracuse 
Research Corporation, an EPA contractor, has identified and summarized 
the existing health and exposure literature on the HAPs, and has 
identified testing programs currently in progress (Refs. 11, 12).
    The NAS report also discussed how a gradual, highly iterative 
testing approach to the generation of health effects data on HAPs might 
work. The report recommended that HAPs could be prioritized on the 
basis of their acute toxicity and chemical structure, and testing might 
proceed stepwise, on a case-by-case basis, from acute toxicity to 
studies of the uptake, distribution, retention, and excretion of the 
substance, to subchronic toxicity, and ultimately, if needed, to 
endpoint testing in animals. Depending on the animal toxicity data 
produced by this iterative testing scheme, according to the NAS, EPA 
might decide that further studies of human toxicity or mechanisms of 
toxicity are warranted.
    Although EPA agrees with the need to prioritize testing, it has 
taken a different approach to prioritization that is based on 
consideration of exposure potential and the rulemaking schedule of 
section 112 of the CAA. The amount and type of existing data vary 
greatly among the chemical substances that Congress designated as HAPs. 
In practice, therefore, no single uniform iterative approach based on 
toxicity factors alone would apply to all chemical substances. For 
example, one HAP might have only acute and short-term test data, while 
longer-term studies might exist for another HAP. Nevertheless, both the 
NAS and EPA approaches recognize that existing data must be considered 
if EPA is to avoid requiring duplicative testing that previously 
produced adequate data.
    An iterative testing approach based on toxicity factors alone would 
be time consuming and require multiple rulemakings. This process would 
take too long to collect useful data for making decisions needed to 
meet upcoming statutory deadlines established in the CAA. Furthermore, 
multiple iterative rulemakings to develop needed test data would be 
prohibitively costly to EPA and would not recognize limitations on EPA 
resources. For Option 3, EPA's preferred testing level, follow-up 
testing would rarely be required beyond that level proposed in this 
rule. Such testing, if necessary, would be required in a separate 
rulemaking.
    To make the multichemical decisions required under section 112 of 
the CAA regarding, for example, residual risk and delisting HAPs, EPA 
believes that it needs a consistent, even database covering HAPs across 
the same broad set of endpoints. EPA believes that Option 3 will permit 
timely gathering of a consistent database on HAPs more efficiently and 
at less cost to industry and EPA than is possible with other 
approaches.

C. Review of Data and Selection of HAPs

    In choosing candidates for this proposed test rule, EPA considered, 
consistent with TSCA section 4 requirements, the potential for a 
chemical substance to present an unreasonable risk of injury to health 
or the environment, the production

[[Page 33184]]

volume of the substance, the amount of emissions produced by the 
chemical substance entering or reasonably anticipated to enter the 
environment or become a source of exposure for humans, the sufficiency 
of the existing database, and the need for further testing to develop 
needed data. Consequently, as indicated in Unit IV of this preamble, 
and explained in a separate document in the record entitled ``TSCA 
Section 4 Findings for 21 Hazardous Air Pollutants'', each candidate 
listed for testing in this proposed rule is:
    (1) Considered to have the potential of presenting an unreasonable 
risk of injury to health or the environment (except in the case of 
ethylene glycol, for which no A finding was made--see the table in Unit 
V of this preamble);
    (2) Produced in quantities exceeding 1,000,000 pounds per year;
    (3) Emitted (i.e., released into the atmosphere) in the amount of 
50 tons (100,000 pounds) per year or more according to the 1993 Toxics 
Release Inventory (TRI);
    (4) Considered to have health effects data needs not addressed in 
other testing and research programs;
    (5) Considered to have health effects data that are insufficient 
under TSCA section 4 for determining effects of the HAP on health; and
    (6) Considered to need further testing to develop the needed data.
    The determination that data are insufficient to ascertain the 
effects of the HAPs on human health is based on several factors. First, 
EPA determined the effects of concern (toxicological endpoints) and the 
depth and quality of data which the Agency needs in order to make 
residual risk determinations. This decision and the range of options 
EPA considered are discussed in Unit III.A. of this preamble. Having 
made the decision that standard endpoint tests are appropriate, EPA 
reviewed existing studies and, for the purposes of this rule, compared 
such studies against the testing methodology used in the 1985 version 
of the EPA test guidelines for these endpoints. The 1985 test 
guidelines were the first test guidelines issued by EPA for its TSCA 
chemical testing program and represent widely accepted, peer-reviewed 
methods for characterizing chemical toxicity.
    The reasons why existing studies were judged to be inadequate are 
explained in a separate document in the record entitled ``TSCA Section 
4 Findings for 21 Hazardous Air Pollutants'', and summarized in the 
table in Unit V of this preamble. The reasons are varied but include 
the following examples--not studying the appropriate endpoint; too few 
dose levels; inappropriately high- or low-dose levels; and too few 
animals to have statistical confidence in the results. Nevertheless, in 
some cases, EPA toxicologists determined that data were adequate when 
the weight of evidence from several flawed studies, which, when 
considered individually were determined to be inadequate, gave an 
adequate characterization of the toxicity of the substance. Thus expert 
judgment must always play a role in determinations of data adequacy. 
Indeed, the determination of adequacy is so intimately connected to the 
unique characteristics of study design for each toxicological endpoint 
that EPA is unable to articulate a universal test of data adequacy that 
might be applied consistently in all situations. EPA is soliciting 
comments on its approach to determining data adequacy for the HAPs.
    To select HAPs for testing, EPA initially reviewed the production 
data and TRI data for all 189 HAPs. EPA realizes that TRI data 
represent estimates of environmental emissions of the TRI-listed 
chemicals and do not account for all chemical substances in the United 
States. Nevertheless, TRI figures offer the most complete, readily 
available emissions data, and EPA has determined that this database is 
sufficient for the purpose of helping EPA select high-emission HAPs for 
consideration as potential test candidates. While publicly available 
sources of production data are cited in the analysis supporting this 
rule, data from these sources were checked against the TSCA chemical 
inventory update production data, most of which are claimed as CBI.
    After reviewing TRI data for all HAPs, EPA decided to select a 
number of HAPs for initial consideration by focusing its attention on 
HAPs with TRI emissions of 50 tons or more per year. The 66 HAPs in 
this group constituted a reasonably sized group for further review. The 
selection of 50 tons per year or more as a cutoff is appropriate 
because this number captures high-emission HAPs and because section 112 
(a)(1) of the CAA, 42 U.S.C. 7412(a)(1), defines ``major source'' as 
emitting ``* * * 10 tons per year or more of any hazardous air 
pollutant or 25 tons per year or more of any combination of hazardous 
air pollutants * * *.''
    A survey of testing conducted by EPA under TSCA section 4, the 
Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), and other 
testing programs supplemented a preliminary review of health findings 
from secondary source documents and the IRIS database. This initial 
survey revealed that certain HAPs having high emissions (50 tons or 
more) already have a large inhalation toxicology database or are 
subject to testing or research in existing programs. Therefore, EPA 
decided not to pursue additional testing under this rule for benzene, 
butadiene, carbon disulfide, chromium, cyanide, ethylene oxide, 
formaldehyde, lead, methanol, methyl tertiary butyl ether, methylene 
chloride, tetrachloroethylene, toluene, trichloroethylene, vinyl 
chloride, and vinyl acetate. Additional testing under TSCA for these 
chemicals may be considered at some time in the future.
    EPA decided that the remaining group of 50 HAPs could be handled 
most efficiently by promulgating more than one rule. Consequently, 21 
high-emission HAPs were scrutinized further and were selected as 
candidates for this proposed rule, and the remaining 29 HAPs were 
deferred for consideration in subsequent HAPs test rulemaking efforts. 
In the second HAPs test rule, EPA plans to focus on persistent HAPs 
that may bioaccumulate. EPA may, therefore, require ecological and 
environmental testing for these HAPs. EPA also may require testing in 
the second rule to collect data needed to implement the ``Great 
Waters'' program of section 112(m) of the CAA, 42 U.S.C. 7412(m).
    During the selection process for this proposed rule, EPA's 
contractor undertook a comprehensive search of the toxicological, 
health, and exposure literature for the 21 HAPs proposed for testing in 
the current rule (Refs. 11, 12). EPA's contractor performed the 
literature search in a stepwise manner to save both time and expense. 
The first step was to review secondary source health effects documents. 
EPA's contractor identified documents published by EPA, the 
International Agency for Research on Cancer (IARC), and ATSDR and 
extracted relevant data. EPA performed online Environmental Mutagen 
Information Center (EMIC) searches for genetic toxicity information 
(Ref. 13). In addition, an article entitled ``Genetic Activity Profiles 
of 110 Hazardous Air Pollutants Listed Under Title III of the Clean Air 
Act'' (Ref. 14) and the International Commission for Protection against 
Environmental Mutagens and Carcinogens (ICPEMC) have provided useful 
summary information.
    EPA realizes that using secondary sources of information is not 
ideal. For example, it is possible that a secondary source document 
could miss an important study or that the document could fail to 
properly interpret a study. Consequently, whenever essential

[[Page 33185]]

information appeared to be missing from the review documents or was not 
explained clearly, EPA's contractor consulted original articles.
    Through its contractor, EPA next checked several sources for 
relevant published and unpublished studies. It obtained unpublished but 
publicly available studies submitted to EPA under TSCA, searched the 
Toxic Substances Control Act Test Submissions (TSCATS) database by CAS 
Registry number, and reviewed the National Toxicology Program (NTP) 
Results Report (generated from NTP's CHEMTRACK database) to locate 
completed but unpublished NTP studies. With the contractor's 
assistance, EPA next undertook an update search of the open literature 
to locate any as yet unidentified studies published either shortly 
before or after the review documents appeared. For this purpose, EPA's 
contractor searched the National Library of Medicine (NLM) TOXLINE 
database for studies published during a period of time beginning three 
years prior to the date of the review document initially used to obtain 
toxicity information and ending on the date of the search.
    In addition, EPA's contractor consulted with representatives of 
NIOSH, OSHA, the Food and Drug Administration (FDA), the National 
Institute of Environmental Health Sciences (NIEHS), and various 
chemical companies. The purpose of these inquiries was to determine if 
these organizations had any information on completed or ongoing studies 
that might not be found in any readily available database. Through its 
contractor, EPA also contacted the Chemical Industry Institute of 
Toxicology (CIIT), as well as trade associations and allied 
organizations to determine whether these organizations were sponsoring 
or knew of any relevant studies currently in progress. Finally, EPA's 
contractor closely reviewed data sheets compiled by EPA's IRIS RfD/RfC 
Working Group to ascertain if the group had identified any additional, 
otherwise unlocated information.
    Varied levels of scrutiny were applied to different types of 
toxicity testing information throughout the literature search. Because 
the primary focus of the review of acute, subchronic, and chronic 
systemic toxicity literature was inhalation exposure, only inhalation 
studies were reviewed for these endpoints. Although oral studies can 
provide important information on target organ toxicity and should be 
considered in the design of any testing protocol, these studies usually 
provide limited information on the effects of a compound on the 
respiratory tract. In addition, the systemic dose remote to the 
respiratory tract for many compounds is affected by modulation of 
uptake at the portal of entry into the body. This modulation is not 
only from first-pass effects but from other influences of anatomy and 
physiology (Ref. 15). Because EPA's literature search did not encompass 
oral acute and subchronic toxicity studies, the preliminary findings of 
risk that EPA is making below, under TSCA section 4(a)(1)(A), are not 
based on such studies. Thus, oral acute and subchronic studies may 
provide additional evidence of potential toxicity.
    The contractor reviewed studies of carcinogenicity, neurotoxicity, 
and reproductive and developmental toxicity, regardless of the route of 
administration.
    EPA took a different approach to identify HAP candidates for 
immunotoxicity testing. EPA relied on an EPA document ``Hazardous Air 
Pollutants: Profiles of Non-Cancer Toxicity from Inhalation Exposures'' 
(Ref. 16), containing a database that was developed from EPA and ATSDR 
documents and data files, and from the Hazardous Substances Data Bank 
(HSDB) of NLM. The contractor searched recent literature (i.e., 1989 to 
present) for immunotoxicity data on the 21 HAPs in both MEDLINE and 
TOXLINE. For chemicals with ATSDR Toxicological Profiles, the profile 
was used to identify immunotoxicity data. Much of the identified 
immunotoxicity literature used rather insensitive indicators of impact 
(e.g., organ weight changes, histopathology, leukocyte counts, and 
total serum protein determinations), that were judged to constitute an 
inadequate evaluation of suppression of immune system responsiveness 
(Ref. 17). Thus, an immunotoxicity screening test is being proposed in 
this rule for many of these HAPs.
    Although EPA has made intense and thorough attempts to identify all 
relevant studies, EPA recognizes the limitations inherent in relying on 
secondary sources and realizes that its literature search may have 
failed to locate studies recently undertaken or completed. Therefore, 
EPA solicits comments bringing to its attention any valid studies not 
identified in its search efforts.

D. Previous TSCA Testing Actions Affecting These Chemical Substances

    Eight of the substances included in this proposed rule have been 
the subject of previous testing under TSCA section 4. Testing by the 
inhalation route was not generally required, however, and acute 
effects--including respiratory tract effects--were not generally a 
target endpoint. This subunit will briefly summarize previous testing 
decisions and explain the relationship between those activities and 
this proposed rule.
    1,1'-Biphenyl was recommended by the Interagency Testing Committee 
(ITC) in its 10th report for environmental effects and chemical fate 
testing (47 FR 22585, May 25, 1982). Focusing only on environmental 
testing, EPA found that 1,1'-biphenyl may present an unreasonable risk 
to the environment and issued a test rule requiring environmental 
effects and chemical fate testing of the chemical on September 12, 1985 
(50 FR 37182). This proposed rule complements the earlier action by 
requiring health effects testing of 1,1'-biphenyl, namely, acute 
toxicity, respiratory sensory irritation, subchronic toxicity, 
developmental toxicity, reproductive toxicity, neurotoxicity and 
immunotoxicity.
    Chlorobenzene was recommended to EPA for health and environmental 
effects testing in the first report of the ITC (42 FR 55026, October 
12, 1977). Subsequently, EPA found that the chemical may present an 
unreasonable risk to human health (an A finding) and issued a rule 
requiring reproductive effects testing (51 FR 24657, July 8, 1986). 
Although the preamble of the proposed rule described specific 
neurotoxicity concerns, EPA stated that neurotoxicity testing 
requirements were not being proposed because it had not issued 
neurotoxicity test guidelines at that time. Instead EPA explained its 
then-current views on neurotoxicity testing in the preamble and 
solicited public comment on those views (45 FR 48524, July 18, 1980). 
Because a neurotoxicity screening battery guideline (OPPTS 870.6200) 
has since been proposed, this rule proposes the testing of 
chlorobenzene for neurotoxicity, acute toxicity, respiratory sensory 
irritation, subchronic toxicity, and immunotoxicity.
    Cresols are members of a chemical category consisting of three 
isomers: ortho-, para-, and meta-cresol. Based on both A and B 
findings, a test rule proposed on July 11, 1983 (48 FR 31812) would 
have required testing of cresols for subchronic toxicity, mutagenicity, 
carcinogenicity, developmental toxicity, reproductive effects, 
neurotoxicity, and skin sensitization. The final rule, published on 
April 28, 1986 (51 FR 15771), which specified testing for all three 
isomers and provided a rationale for this decision, required testing 
for mutagenicity, developmental toxicity, and reproductive effects. 
Data received

[[Page 33186]]

under this test rule satisfy the HAPs data needs for these endpoints. 
Based on the results from this first tier of tests, a conditionally 
required cancer bioassay was not triggered. In addition, oral 
subchronic toxicity studies and subchronic neurotoxicity studies were 
conducted by EPA's Office of Solid Waste. In accordance with the need 
for data on respiratory tract effects, today's rule proposes acute and 
subchronic inhalation toxicity, respiratory sensory irritation, acute 
neurotoxicity, and immunotoxicity tests for all three cresol isomers 
(see Unit IV.B. of this preamble). For the purposes of this proposal, 
the three cresol isomers are counted as a single chemical.
    Methyl isobutyl ketone was the subject of a negotiated testing 
agreement between EPA and industry for mutagenicity, developmental 
toxicity, and subchronic testing (47 FR 58025, December 29, 1982, and 
48 FR 44905, September 30, 1983). Data received under the negotiated 
testing agreement satisfy the HAPs data needs for these endpoints. 
Methyl isobutyl ketone is also being tested for neurotoxicity under a 
TSCA enforceable consent agreement (ECA) with industry (announced at 60 
FR 4514, January 23, 1995 (FRL-4924-8)). This rule proposes testing for 
reproductive toxicity, acute toxicity, respiratory sensory irritation, 
and immunotoxicity to complement ongoing testing and existing data.
    Phenol is the subject of a test rule proposed on the basis of A and 
B findings on November 22, 1993 (58 FR 61654). That rule proposed 
subchronic toxicity, neurotoxicity, and reproductive and developmental 
toxicity testing and a study of phenol's pharmacokinetics. EPA has 
received a proposal for an ECA for this chemical substance that would 
cover the testing proposed in the 1993 rule. The rule proposed herein 
would add acute inhalation toxicity, respiratory sensory irritation, 
and immunotoxicity to the testing program for phenol. Under the 
procedures set forth at 40 CFR 790.22, members of the CMA Phenol Panel 
and EPA have negotiated an ECA which provides for the testing proposed 
in November 1993 as well as additional testing, including 
immunotoxicity. Such testing would meet the HAPs-related data needs for 
phenol. If the ECA is successfully concluded, EPA will drop the testing 
requirement for phenol from the final HAPs rule.
    1,2,4-Trichlorobenzene has been tested for carcinogenicity under a 
test rule (51 FR 24657, July 8, 1986) based on an A finding. Data 
received under this test rule satisfy the HAPs data needs for this 
endpoint. Although the preamble of the proposed rule described specific 
neurotoxicity concerns, EPA stated that neurotoxicity testing 
requirements were not being proposed because it had not issued 
neurotoxicity test guidelines at that time (45 FR 48545, July 18, 
1980). Because a neurotoxity screening battery guideline (OPPTS 
870.6200) has since been proposed, this rule proposes the testing of 
1,2,4-trichlorobenzene for acute toxicity, respiratory sensory 
irritation, neurotoxicity, immunotoxicity, and developmental toxicity.
    Oncogenicity testing for vinylidene chloride was called for in a 
proposed test rule based on an A finding on August 12, 1986 (51 FR 
28840). The rule proposed that distribution, metabolism, and excretion 
studies and an inhalation oncogenicity study be conducted in mice on 
behalf of EPA's Office of Air Quality Planning and Standards (OAQPS). 
EPA has not finalized the vinylidene chloride proposal and is hereby 
withdrawing it. EPA is not pursuing these studies because the Agency 
has concluded that, at this time, an oncogenicity bioassay would do 
little to add to EPA's understanding of the oncogenic potential of the 
substance. Today's rule proposes testing for acute toxicity, 
respiratory sensory irritation, and neurotoxicity.

IV. Proposed Testing

A. Testing and Reporting Requirements

    EPA is proposing specific testing and reporting requirements for 
each of the 21 HAPs as specified in table 1 in Sec. 799.5053(a)(5) of 
this proposed rule. EPA is proposing for the first time in a TSCA 
section 4 rule to require an immunotoxicity screen and an acute 
inhalation toxicity test that focuses on respiratory damage and 
sublethal systemic toxicity. These and other test guidelines are 
discussed below in Unit IV.C. of this preamble.
    EPA is proposing to require a modified inhalation carcinogenicity 
bioassay using only the male rat and female mouse when existing oral 
carcinogenicity data and supporting information for a chemical 
substance are deemed too uncertain to determine its carcinogenicity via 
inhalation (Ref. 10). The reduced protocol is less expensive than a 
traditional bioassay. However, test sponsors would also have the 
alternative of performing pharmacokinetics studies and using route-to-
route extrapolation from existing adequate oral toxicity data under 
enforceable consent agreements (EDAs) in lieu of this and other test 
requirements if the Agency decides to use this approach (see Units 
IV.D. and IV.E. of this preamble).
    A total of 21 months would be given for the submission of final 
reports for acute toxicity testing because the acute inhalation 
toxicity with histopathology guideline proposes to make certain 
histopathology studies contingent upon the results of the 90-day 
subchronic studies. The time for the submission of immunotoxicity 
studies would vary as a function of the test with which they can be 
combined (e.g., subchronic and reproductive effects).

B. Test Substance

    EPA is proposing that a substance of at least 97% purity be used as 
the test substance. EPA recognizes that exposure to HAPs will occur as 
exposure to complex mixtures and that ideally one would like data on 
the mixtures themselves. However, it is not practical to test mixtures 
due to the huge number of possible combinations. EPA will thus evaluate 
the toxicity of HAP mixtures using data on the relatively pure 
components in order to avoid the possible confounding effects of 
impurities that might be found in technical grade substances. These 
impurities, if substantial contributors to air pollution, should also 
be captured as separate entries on the CAA list of HAPs. EPA believes 
that a purity of 97% is available or readily achievable for all 
substances covered by this rule.
    For cresols, the subject of the test rule is a mixture (CAS No. 
1319-77-3) of three isomers: ortho- (CAS No. 95-48-7), para- (CAS No. 
106-44-5) and meta- (CAS No. 108-39-4). The mixture and individual 
isomers are contained in the CAA section 112(b)(1) list of hazardous 
air pollutants. Most human exposure is to the mixture. However, because 
the mixture is of variable composition, EPA believes that it would be 
very burdensome to test every possible variation of the mixture, which 
would have different proportions of isomers. Therefore EPA is proposing 
to follow the approach taken in the final test rule for cresols (51 FR 
15771, 15776, April 28, 1986) and test each isomer (see Unit III.D. of 
this preamble).
    Another critical factor in study design for HAP testing is the low 
vapor pressure of several of these substances (diethanolamine, 1,1'-
biphenyl, phthalic anhydride). This raises two questions. To which 
forms of the chemical are humans exposed--vapor, aerosol or particle? 
How does one design a valid toxicity study that can be used to assess 
human risk to such exposures? Given the reported TRI releases to the 
atmosphere for these substances, EPA has assumed that exposures are to

[[Page 33187]]

aerosols or particulates from the condensation of high temperature 
stack gases. EPA is proposing that diethanolamine, 1,1'-biphenyl and 
phthalic anhydride be tested via aerosol exposure. EPA invites 
manufacturers and processors to submit information about the forms of 
these substances that are encountered in ambient exposures and the 
forms that should be tested, and encourages the development of 
pharmacokinetics data that would permit testing by the less expensive 
oral route for HAPs with low vapor pressure.

C. Test Guidelines

    The 11 guidelines being proposed for use in testing HAPs under this 
rule are included in the recently harmonized health effects test 
guidelines proposed by EPA's Office of Prevention, Pesticides, and 
Toxic Substances (OPPTS). When final, these harmonized guidelines will 
incorporate an updated version of the test guidelines previously 
developed for use under TSCA and FIFRA into a single set. A notice of 
availability and request for comments on the proposed guidelines was 
published in the Federal Register of June 20, 1996 (61 FR 31522).
    The 11 guidelines proposed for use in testing HAPs are included in 
the public version of the record for this rulemaking at the address 
specified in the ``ADDRESSES'' section of this document. The complete 
set of proposed guidelines is available electronically from the EPA 
Public Access Gopher (gopher.epa.gov) under the heading: 
``Environmental Test Methods and Guidelines''; by internet e-mail: 
[email protected]; by mail: Public Docket and Freedom of 
Information Section, Field Operations Division (7506C), Office of 
Pesticide Programs, U.S. Environmental Protection Agency, Washington, 
DC 20460; or in person or for courier pick-up: Room 1132, CM #2, 1921 
Jefferson Davis Highway, Arlington, VA; telephone: (703) 305-5805.
    The 11 guidelines proposed to be used for testing HAPs are as 
follows:
    (1) Acute Inhalation Toxicity with Histopathology, OPPTS 870.1350, 
EPA Pub. No. 712-C-96-291, June 1996;
    (2) Subchronic Inhalation Toxicity, OPPTS 870.3465, EPA Pub. No. 
712-C-96-204, June 1996;

Assay, OPPTS 870.5395, EPA Pub. No. 712-C-96-226, June 1996;
    (10) Neurotoxicity Screening Battery, OPPTS 870.6200, EPA Pub. No. 
712-C-96-238, June 1996; and
    (11) Immunotoxicity, OPPTS 870.7800, EPA Pub. No. 712-C-96-351, 
June 1996.
    To be considered in this rulemaking, comments on the 11 proposed 
test guidelines that are specific to HAPs testing must be submitted to 
the OPPT Document Control Office. The comments must be submitted in the 
manner specified in the ``DATES'' and ``ADDRESSES'' sections at the 
beginning of this document. Comments on the 11 proposed guidelines, 
which are not specific to the HAPs test rule must be submitted to the 
Office of Pesticide Programs by August 19, 1996, at the address 
identified in the Federal Register of June 20, 1996 (61 FR 31522).
    The process of developing OPPTS harmonized guidelines described 
above is proceeding at the same time as the development of the HAPs 
test rule. The OPPTS harmonization process may result in the revision 
of the guidelines prior to the end of the ocmment period for this 
proposed rule. If so, EPA will announce the availability of those of 
the 11 guidelines used in the HAPs rule that have been revised in order 
to allow for public comment on the applicability of the revised 
guidelines to the HAPs rule. If any of these 11 guidelines has not been 
revised by the end of the comment period for this proposed rule, EPA 
may issue the corresponding HAPs-specific guideline independent of the 
OPPTS harmonization process.
    EPA is proposing to modify the subchronic inhalation toxicity test 
guideline (OPPTS 870.3465) for the purposes of this rulemaking to 
include enhanced histopathology of the respiratory tract and an assay 
for cell damage via lung lavage. EPA is requesting comment on adding 
these parameters to the subchronic test guideline for testing HAPs.
    As part of this rulemaking, EPA proposes to use the acute 
inhalation toxicity with histopathology test guideline (OPPTS 
870.1350). As indicated in Unit III.A. of this preamble, the study of 
sublethal effects, especially effects on the respiratory system, 
associated with accidental release and acute exposures is neces
FR Doc. 96-16203 Proposed Test Rule for Hazardous Air Pollutants
sary for 
the HAPs. The standard acute inhalation toxicity test guideline (OPPTS 
870.1300) focuses on gross lesions, body weight changes, and effects on 
mortality. The acute inhalation toxicity with histopathology test 
guideline assesses two endpoints: (1) histopathology of the respiratory 
tract, kidney, liver, and other target organs; and (2) cell damage via 
lung lavage. The guideline takes a stepwise approach to the evaluation 
of acute toxicity and initially requires a 4-hour exposure at three 
concentration levels. If the 4-hour study shows positive results in 
histopathology or the bronchoalveolar lavage, a 1-hour study and an 8-
hour study would be required to define better the time and 
concentration dependence of acute exposures. Histopathology is being 
proposed for the respiratory tract, liver, and kidney. Other target 
organs identified by either gross pathology in the 4-hour acute study 
or by histopathology in the 90-day study would also have to be examined 
by histopathology in the 4-hour acute study. If these results are 
positive in the 4-hour study, histopathology in the 1-hour and 8-hour 
studies would be required. The 4-hour acute testing may be combined 
with acute neurotoxicity testing.
    A respiratory sensory irritation test using American Standard Test 
Method (ASTM) E 981-84 is also being proposed to provide a quantitative 
estimate of the sensory irritant potential of an inhaled chemical. 
Irritation is detected by a characteristic change in the breathing 
pattern of mice, which results in a reduction in the breathing rate 
during exposure to a test atmosphere.
    For all testing proposed in this rule, test sponsors would have to 
conduct testing and generate data in accordance with the specified test 
guideline. Data developed under the final rule must be reported in 
accordance with TSCA Good Laboratory Practice (GLP) Standards, 40 CFR 
part 792.
    EPA is considering three alternative procedures for handling these 
test guidelines in the context of the final HAPs test rule. The first 
alternative is for the final HAPs rule to incorporate the guidelines by 
reference. Under this alternative, the text of the guideline would not 
appear in the Code of Federal Regulations. Instead the rule would 
include a reference to the guideline which would be available on the 
internet and elsewhere, as noted above.

[[Page 33188]]

A copy of the applicable guideline would also be maintained in the 
public version of the rulemaking record.
    The second alternative would be for the final HAPs rule to refer to 
the guideline, the text of which would be available on the internet and 
elsewhere, as the pre-approved protocol. However, test sponsors may use 
other protocols after such protocols have been approved by EPA 
(``previously approved equivalents''). If EPA decides on this course of 
action, the Agency may issue a supplemental notice proposing specific 
implementation procedures if they are significantly different from the 
following procedures. A test sponsor would be required to submit to EPA 
for review and approval each test protocol that such sponsor believes 
is equivalent to the corresponding OPPTS test guideline. A submission 
would have to demonstrate equivalency, include a description of the 
differences between the sponsor's protocol and the corresponding OPPTS 
guideline, and indicate the rationale for changing the guideline. The 
deadline for these submissions would be 90 days after the effective 
date of the final HAPs rule. In the case of a study where the design 
depends upon the results of an earlier test (such as carcinogenicity 
where the dose level is contingent upon the results of a subchronic 
study), the deadline is 90 days following the date of submission of the 
final report for that study.
    The third alternative is for the final HAPs rule to reference the 
guidelines currently in part 798 of title 40 of the Code of Federal 
Regulations and modify these guidelines to make them as nearly 
identical as possible to the harmonized OPPTS guidelines. The 
modifications that the Agency currently believes would be appropriate 
are set forth in a separate document in the record entitled 
``Modifications to Health Effects Test Guidelines Currently in 40 CFR 
Part 798 for Use in the HAPs Test Rule''. EPA is soliciting comment on 
these three alternative procedures.

D. Route-to-Route Extrapolation

    EPA would consider route-to-route extrapolation of toxicity data 
from routes other than inhalation when it is scientifically defensible 
to empirically derive the inhalation risk. Derivation of the inhalation 
risk is generally only reasonable when portal-of-entry effects (toxic 
effects on the respiratory tract from inhalation exposure) and/or 
first-pass effects can be ruled out or adequately characterized.
    ``First-pass'' effects refer to the metabolism that can take place 
in portal-of-entry tissue, prior to a chemical's entry into the 
systemic circulation. For example, after oral administration, many 
chemicals are delivered to the liver via the portal vein from the 
gastrointestinal (GI) tract before they enter into the systemic 
circulation. The respiratory tract can also exhibit a first-pass effect 
after inhalation due to its various cell types and metabolic enzyme 
systems. The first-pass action can alter the disposition of the parent 
and metabolites, thereby modulating the dose to remote or systemic 
target tissues in a route-dependent fashion. Therefore, unless this 
first-pass effect and dosimetry are adequately understood and taken 
into account, substantial error can be introduced in route-to-route 
extrapolation.
    In the absence of data to determine dosimetry via inhalation, 
quantitative route-to-route extrapolation is subject to substantial 
error when a chemical is thought to be susceptible to first-pass 
effects (e.g., metabolized) or when a potential for portal-of-entry 
effects is indicated (e.g., skin irritation after dermal 
administration). There are situations where oral data should not be 
used for route extrapolation to inhalation. For example, chemicals with 
a short active half-life that were administered by gavage may result in 
high short-term blood concentrations and consequently much greater 
effects than the much lower constant blood levels that occur with 
inhalation exposure. Conversely, if a chemical requires metabolic 
activation via a rate-limited reaction, bolus dosing via gavage may 
underestimate the dose. Consideration of factors such as these is 
important in judging whether the oral study of interest qualifies for 
route extrapolation.
    Regardless of the toxic endpoint considered, EPA's ability to 
perform quantitative route-to-route extrapolation is critically 
dependent on the amount and type of data available. The minimum 
information generally needed includes both the nature of the toxic 
effect and a description of the relationship between exposure and the 
toxic effect. The actual impact of exposure by different routes can 
best be estimated by taking account of factors that influence 
absorption at the portal of entry, such as:
    (1) Physicochemical characteristics of the chemical (e.g., 
disassociation state, molecular weight, partition coefficient, 
reactivity, solubility);
    (2) Exposure factors (e.g., concentration, duration, regimen); and
    (3) Physiologic parameters (e.g., barrier capacity as related to 
variability in species, blood flow, cell types and morphology, 
metabolism, pH, specialized absorption sites, storage in cells) and 
those parameters that influence dose that are remote to the portal of 
entry including metabolism, clearance, tissue binding, tissue blood 
flows, tissue:blood partition coefficients, and tissue volumes.
    Oral toxicity data are the most commonly available data as 
alternatives to inhalation data. Oral data are problematic for route-
to-route extrapolation in the following instances:
    (1) When groups of chemicals are expected to have different 
toxicities by the two routes, for example, metals, irritants, and 
sensitizers.
    (2) When a first-pass effect by the liver is expected.
    (3) When a respiratory tract effect is established but nodosimetry 
comparison can be clearly established between the two routes.
    (4) When the respiratory tract was not adequately studied in the 
oral studies.
    (5) When short-term inhalation studies, dermal irritation, or in 
vitro studies indicate potential portal-of-entry effects at the 
respiratory tract, but the studies themselves are not adequate for risk 
assessment.
    Dose-response data from other routes of exposure, such as 
intravenous, intraperitoneal, subcutaneous, dermal, and intramuscular 
routes also may be available. Intravenous data can provide reliable 
information on blood levels, but such information should be 
supplemented by knowledge of the quantitative relationship between 
exposure concentration and blood levels in order to be useful. The 
other routes usually are less useful in route-to-route extrapolation 
because the pharmacokinetics are, in general, poorly characterized.
    Methods for route-to-route extrapolation vary in accuracy and, 
therefore, in inherent uncertainty. The simplest approach is to use 
default absorption values for each exposure route dependent on the 
chemical class in question. Such values have only been developed for a 
few classes of organic chemicals. Because this approach entails 
increased uncertainty compared with those that use pharmacokinetics 
(PK) data and physiologically based pharmacokinetics (PBPK) modeling, 
use of default absorption values is generally considered highly 
uncertain for quantitative dose-response assessment.
    EPA's optimal but most complex and data intensive method for 
performing route-to-route extrapolation involves the development of a 
PBPK model that describes the disposition (deposition, absorption, 
distribution, metabolism, and elimination) of the chemical for the 
routes of interest (Ref. 15). Such models

[[Page 33189]]

account for fundamental physiological and biochemical parameters and 
processes such as blood flows, ventilatory parameters, metabolic 
capacities, and renal clearance tailored by the physicochemical (e.g., 
blood:air and tissue:blood partitions) and biochemical properties 
(e.g., binding, depletion of cofactors) of the chemical in question. 
PBPK models should be used in conjunction with toxicity and mechanistic 
studies in order to relate the effective dose associated with an 
adverse effect for the test species and conditions to other scenarios. 
Although the development of a full PBPK model can involve greater 
effort than other methods using pharmacokinetics data, the application 
of pharmacokinetics modeling to determine health risk provides a 
considerable improvement in the reliability of an extrapolation across 
routes. The use of an existing model structure, essentially a template, 
can greatly reduce the effort required for model development of 
analogous chemicals.
    More limited pharmacokinetics data such as measurement of 
bioavailability and disposition of an internal dose marker (e.g., blood 
cholinesterase activity, enzyme elevation, and amount of chemical bound 
to protein) may be used for route-to-route extrapolation in conjunction 
with a consideration of the uncertainties involved in each case. As 
above, if the portal of entry is affected by the agent, then more 
elaborate data may be required.
    EPA realizes that the use of pharmacokinetics data for route-to-
route extrapolation, as well as for the broader purpose of generally 
identifying the mechanisms by which exposure to a specific agent causes 
particular health effects, is a fast-developing and often controversial 
area of science at this time. However, under certain circumstances, as 
explained above, route-to-route extrapolation based on valid 
pharmacokinetics data can offer a useful and less expensive alternative 
to testing or retesting by another route of exposure.

E. Opportunity To Submit Proposals for Enforceable Consent Agreements 
for Pharmacokinetics Studies

    Basic pharmacokinetics parameters provide information on a 
substance's absorption, distribution, biotransformation, and excretion 
which can aid in understanding the potential for accumulation of the 
substance in various tissues or organs and the mechanism of toxicity. 
Basic PK parameters can be determined through use of the OPPTS 
harmonized test guideline for pharmacokinetics studies (870.7485). EPA 
considered but rejected the option of requiring the use of this 
guideline in this proposed rule because the Agency is interested in a 
more sophisticated level of study that could potentially support PBPK 
modeling.
    EPA believes that enforceable consent agreements (ECAs) and testing 
consent orders offer an opportunity to obtain this more in-depth 
understanding of the pharmacokinetics of HAPs. The Agency, therefore, 
is inviting manufacturers to submit proposals for pharmokinetics 
studies for HAPs to be used in the ECA process. Each study proposal 
should include the name of the chemical(s), a detailed description of 
the proposed pharmacokinetics study, and discussion of the application 
of the pharmacokinetics data in performing route-to-route 
extrapolations. Study proposals should reflect an understanding of the 
scientific reasoning presented in Unit IV.D. of this preamble, the 
existing database on the chemical and testing required under this 
proposed test rule. EPA expects to use a previously published decision 
tree (Ref. 15) as an element in the evaluation of these proposals. As 
noted in Unit IV.D., these data may be used for route-to-route 
extrapolation with a level of uncertainty in inverse proportion to 
their level of complexity and sophistication.
     Each study proposal should be labeled: ``Proposal for 
Pharmacokinetics Study of (name of chemical),'' identified by document 
control number (OPPTS-42187B, FRL-4869-1), and sent to: U.S. 
Environmental Protection Agency, Office of Pollution Prevention and 
Toxics, Document Control Office (7407), Room G-099, 401 M St., SW., 
Washington, DC 20460. Proposals for pharmacokinetics studies must be 
received by EPA no later than October 24, 1996. Enforceable consent 
agreements must be negotiated and signed no later than 12 months after 
the date of proposal of this rule in order to permit timely development 
of the final HAPs rule.
    EPA will review the submissions and will select promising 
candidates for negotiation under the procedures in 40 CFR 790.22. If 
the Agency decides to proceed with the ECA process, it will publish a 
notice in the Federal Register soliciting persons interested in 
participating in or monitoring negotiations for the development of ECAs 
for PK studies to notify the Agency in writing.
    EPA noted in Unit IV.D. that the development and use of a PBPK 
model represents the optimal approach to route-to-route extrapolation. 
The development of such models is often a complex and uncertain task 
that in most cases lies beyond the expectations of performance that 
could be embodied in an ECA. However, EPA would like to encourage 
extension of the data generated under the ECAs described above to the 
development of PBPK models. EPA envisions that PBPK models could be 
developed through voluntary cooperative arrangements and is interested 
in a dialogue with industry and others on ways to encourage and support 
PBPK model development.

F. Persons Required To Test

    Based on the findings in Unit V of this preamble, EPA is proposing 
that persons who manufacture (including import) or process, or who 
intend to manufacture or process 1,1'-biphenyl, carbonyl sulfide, 
chlorine, chlorobenzene, chloroprene, cresols (all three isomers), 
diethanolamine, ethylbenzene, ethylene dichloride, ethylene glycol, 
hydrochloric acid, hydrogen fluoride, maleic anhydride, methyl isobutyl 
ketone, methyl methacrylate, naphthalene, phenol, phthalic anhydride, 
1,2,4-trichlorobenzene, 1,1,2-trichloroethane, and vinylidene chloride, 
other than as an impurity, at any time from the effective date of the 
final test rule to the end of the reimbursement period, be subject to 
the testing requirements in this rule. Manufacturers would be required 
to submit letters of intent to conduct testing or exemption 
applications (40 CFR 790.45). However, under 40 CFR 790.42, processors, 
small-quantity manufacturers, and manufacturers of small quantities of 
these substances solely for research and development purposes would not 
be required to submit letters of intent or exemption applications 
unless directed to do so in a subsequent notice as described in 40 CFR 
790.48(b).
    EPA is proposing to exempt those manufacturers and processors that 
produce the chemical substances listed above only as an impurity, as 
defined in 40 CFR 790.3, because it would be difficult and 
prohibitively expensive for EPA, manufacturers, and processors to 
identify with complete assurance all chemical substances that contain 
the 21 substances solely as an impurity. In addition, EPA would find it 
difficult to apply both the exemption and reimbursement processes to 
those who manufacture and/or process these chemical substances solely 
as an impurity. EPA's reimbursement regulations, issued pursuant to 
TSCA section 4(c), 15 U.S.C. 2603(c), state that those persons who 
manufacture or process chemical substances as impurities are not 
subject to test

[[Page 33190]]

requirements unless a particular test rule specifically states 
otherwise (40 CFR 791.48(b)). EPA finds no basis to propose such a 
requirement in this rule.
    Persons who manufacture these substances as byproducts, as defined 
in 40 CFR 791.3(c), would be subject to the testing requirements set 
forth in this proposed rule. The total amount of imports and domestic 
production of these chemical substances, including the amount produced 
as a byproduct, would be used in determining reimbursement shares under 
the TSCA section 4 data reimbursement regulations in 40 CFR part 791. 
In a previous multichemical test rule (undertaken for EPA's Office of 
Solid Waste) for which EPA had likewise proposed that byproducts be 
subject to the rule, an industry commenter objected to this inclusion 
based on historical grounds. The commenter said, ``The historical roots 
of section 4 in the Eckart Subcommittee work on TSCA were the sharing 
of the costs of test generation in direct proportion to the economic 
benefits which producers derived from the chemicals.'' In response to 
this comment, EPA explained that,

    EPA does not agree that the intention of Congress to have 
producers share the cost of testing should be interpreted to exclude 
producers of byproducts from TSCA section 4 testing requirements. 
While economic benefit is not derived directly from the production 
of the subject chemical, the production and disposal of the 
byproduct are a result of a production process by which the company 
does derive economic benefit (an indirect benefit). (53 FR 22300, 
22305, June 15, 1988)

    Carbonyl sulfide would be the first chemical substance subject to a 
TSCA section 4 test rule that is produced almost exclusively as a 
byproduct. Although some carbonyl sulfide is reported to be used in 
chemical synthesis, its large production and release, as reported in 
the TRI, is due to its creation as a byproduct which is unwanted. 
Consistent with EPA's position on byproducts testing, as explained 
above, all persons reporting the release of carbonyl sulfide in the TRI 
would be considered to be manufacturers of carbonyl sulfide and would 
be subject to the provisions of this proposed rule.

V. Findings

    As explained in Unit I of this preamble, EPA is proposing findings 
under TSCA sections 4(a)(1)(A) and 4(a)(1)(B) for the 21 HAPs subject 
to this rule. The findings are summarized in the table below. The 
detailed discussion of the findings for each chemical substance 
included in this rule is contained in a separate document entitled 
``TSCA Section 4 Findings for 21 Hazardous Air Pollutants'' that is 
available in the rulemaking record. Requirements for sections 
4(a)(1)(A) and 4(a)(1)(B) findings appear in Unit I of this preamble.
    In articulating its policy for making findings under TSCA section 
4(a)(1)(B) (frequently described as the ``B policy'', see Unit I of 
this preamble), EPA has defined ``substantial production'' as aggregate 
annual production of 1 million pounds or more and ``substantial 
release'' as an annual release, from all sources, into the environment 
of 1 million pounds or 10% of production, whichever is lower (58 FR 
28736, 28746, May 14, 1993). These definitions apply to the terms 
``substantial production'' and ``substantial release'' as used in this 
preamble. (As explained in Unit III.C. of this preamble, all the 
chemical substances proposed for testing in this proposed rule are 
emitted into the atmosphere in the amount of 50 tons per year or more 
according to the TRI.) EPA also defined ``substantial human exposure'' 
as an annual exposure of 100,000 members of the general population, 
10,000 consumers, or 1,000 workers. Id.

VI. Economic Analysis of the Proposed Rule

    EPA has prepared and placed in the record for this proposed rule an 
economic analysis that evaluates the potential for significant economic 
impacts as a result of the testing proposed in this notice. The total 
cost of this proposed rule is estimated to range up to $41.4 million. 
The total cost of testing for each chemical substance has been 
annualized and compared with annual revenues (defined as the product of 
sales price and total supply) as an indication of potential economic 
impact. Annualized test costs, calculated over 15 years using a 7% 
discount rate, represent the equivalent constant costs that would have 
to be recouped each year of the payback period to finance the testing 
expenditure in the first year. Annualized test costs are then divided 
by the total supply of the chemical substance to derive the annualized 
unit test costs. The percent price impact is calculated by dividing the 
annualized unit test costs by the sales price and multiplying by 100.
    The upper-bound estimated total costs of testing (including both 
laboratory costs and administrative costs), annualized tests costs, and 
price impact for the chemicals in this proposed rule are as follows:

    Note: The table shows the maximum costs and impacts estimated by 
EPA. The full range of estimates is given in the economic analysis 
document placed in the record for this proposed rule.
    EPA believes, on the basis of these calculations, that the proposed 
testing of the HAPs presents a low potential for adverse economic 
impact. Because these chemical substances have relatively large 
production volumes, with the exception of carbonyl sulfide (to which 
this methodology does not apply) the annualized costs of testing, 
expressed as a percentage of annual revenue, are very small--ranging 
from 0.0003% to 0.64%. Costs of testing are therefore found to be 
insignificant relative to revenues for these chemical substances.

VII. Availability of Test Facilities and Personnel

    Although earlier studies indicated that test facilities and 
personnel were available to perform the testing specified in this 
proposed rule (Ref. 18), the impact of this rule combined with other 
testing requirements may exceed capacity for inhalation testing 
facilities in the short term. While EPA believes that over the longer 
term, additional inhalation facilities will become available, any 
short-term effects can be dealt with by adjusting study due dates in 
response to comments on this rule or in response to a request for 
modification of reporting deadlines.

VIII. Public Meeting

    EPA will hold a public meeting in Washington, DC prior to the close 
of the comment period. Announcemment of this meeting will be published 
in the Federal Register. If requested, EPA will hold an additional 
public meeting in Washington, DC.

IX. Comments Containing Confidential Business Information

    All comments will be placed in the public version of the rulemaking 
record unless they are clearly labeled as containing information 
claimed as CBI when they are submitted. CBI claims will be deemed to 
have been waived if they are not made at the time of submission of the 
document containing the information claimed as CBI, and such document 
may be made public with no further notice to the submitter. While a 
part of the rulemaking record, comments claimed as CBI will be treated 
in accordance with 40 CFR part 2. A sanitized version of all comments 
containing information claimed as CBI must be submitted to EPA for 
inclusion in the public version of the rulemaking record.
    It is the responsibility of the submitter to comply with 40 CFR 
part 2 so that all materials claimed as CBI may be properly protected. 
This includes, but is not limited to, clearly indicating on the face of 
the revelant section of the comment (as well as on any revelant 
associated correspondence) that information claimed as CBI is included 
and marking ``CONFIDENTIAL,'' ``TSCA CBI,'' or similar designation on 
the face of each section of any document or attachment in the comment 
that contains information claimed as CBI. Should putatively private 
information be put into the public file because of the submitter's 
failure to clearly claim and designate its confidential claim on the 
face of the comment, EPA will presume any such information that has 
been in the public file for more than 30 days to be in the public 
domain.

X. Rulemaking Record

    EPA has established a record for this rulemaking (docket number 
OPPTS-42187) (including comments and data submitted electronically). 
This record contains the basic information considered by EPA in 
developing this proposal and appropriate Federal Register notices. EPA 
will supplement this record as necessary.
    A public version of this record, including printed, paper versions 
of electronic comments, which does not include any information claimed 
as CBI is available for inspection from 12 noon to 4 p.m., Monday 
through Friday, except legal holidays. The public record is located in 
the TSCA Nonconfidential Information Center, Rm. NE-B607, 401 M St., 
SW., Washington, DC 20460.
    Comments in electronic form may be submitted directly to EPA at:
    [email protected]
    Comments in electronic form must be submitted in an ASCII file 
avoiding the use of special characters and any form of encryption.
    The official record for this rulemaking, as well as the public 
version, will be kept in paper form. Accordingly, EPA will transfer all 
comments received electronically into printed, paper form as they are 
received and will place the paper copies in the official rulemaking 
record which will also include all comments submitted directly in 
writing.
    The record includes the following information.

XI. Regulatory Assessment Requirements

A. Executive Order 12866

    Pursuant to Executive Order 12866 (58 FR 51735, October 4, 1993), 
it has been determined by OMB that this is a ``significant regulatory 
action.'' OMB was concerned that the amount of inhalation testing 
required by this rule may exceed the capacity of the testing industry, 
at least in the short run. This action was submitted to OMB for review, 
and any comments or changes made during that review have been 
documented in the public record.
    In addition, EPA has prepared an economic analysis of the impact of 
this

[[Page 33196]]

action, which is contained in a document entitled ``Test Rule Support 
for 21 Hazardous Air Pollutants.'' This document is available as a part 
of the public record at the address listed in Unit X of this preamble 
and is briefly summarized in Unit VI of this preamble.

B. Regulatory Flexibility Act

    Under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.), EPA 
has determined that this test rule, if promulgated, would not have a 
significant impact on small businesses. EPA has identified the entities 
that currently manufacture or import the chemical substances required 
to be tested under this proposed rule and examined the practices that 
industry uses in carrying out chemical testing in response to EPA test 
rules. EPA believes that: (1) small businesses would not be expected to 
perform testing themselves, or to participate in the organization of 
the testing effort, because health effects testing of chemical 
substances is generally carried out by consortia of the large 
manufacturers or importers of the chemical substances; (2) small 
businesses would experience only very minor costs, if any, in securing 
exemption from testing requirements because exemption request 
requirements, described at 40 CFR 790.82, are minimal--particularly 
when, as in this proposed rule, EPA is not requiring exemption 
applicants to submit equivalence data (see Unit IV.F of this 
preamble)--and EPA does not charge a fee for filing such requests; and 
(3) small businesses are unlikely to be affected by reimbursement 
requirements because under the reimbursement rules (at 40 CFR 791.40 
through 791.52), manufacturers or importers with a significant share of 
production or importation are the entities that must share testing 
costs under the reimbursement rules, and small businesses generally do 
not manufacture or import a significant portion of high-volume chemical 
substances.

C. Paperwork Reduction Act

    OMB has approved the information collection requirements contained 
in this proposed rule under the provisions of the Paperwork Reduction 
Act, 44 U.S.C. 3501 et seq., and has assigned OMB control number 2070-
0033.
    The public reporting burden for this collection of information is 
estimated to average approximately the following number of hours per 
response for the chemicals listed below, including time for reviewing 
instructions, searching e
FR Doc. 96-16203 Proposed Test Rule for Hazardous Air Pollutants
xisting data sources, gathering and 
maintaining the data needed, and completing and reviewing the 
collection of information.

    The total public reporting burden is estimated to be 357,045 hours 
for all responses. The overall average per chemical is 15,524 hours.
    Burden means the total time, effort, or financial resources 
expended by persons to generate, maintain, retain, or disclose or 
provide information to or for a Federal agency. This includes the time 
needed to review instructions; develop, acquire, install, and utilize 
technology and systems for the purposes of collecting, validating, and 
verifying information, processing and maintaining information, and 
disclosing and providing information; adjust the existing ways to 
comply with any previously applicable instructions and requirements; 
train personnel to be able to respond to a collection of information; 
search data sources; complete and review the collection of information; 
and transmit or otherwise disclose the information.
    An Agency may not conduct or sponsor, and a person is not required 
to respond to a collection of information unless it displays a 
currently valid OMB control number. The OMB control numbers for EPA's 
regulations are listed in 40 CFR part 9 and 48 CFR chapter 15.
    Comments are requested on the Agency's need for this information, 
the accuracy of the provided burden estimates, and any suggested 
methods for minimizing respondent burden, including through the use of 
automated collection techniques. Send comments on the ICR to Sandy 
Farmer, OPPE Regulatory Information Division; U.S. Environmental 
Protection Agency (2136), 401 M St., SW., Washington, DC 20460, (202) 
260-2740, or electronically by sending an e-mail message to: 
[email protected]. Send a copy of these comments to the 
Office of Information and Regulatory Affairs, Office of Management and 
Budget, 725 17th St., NW., Washington, DC 20503, marked ``Attention: 
Desk Officer for EPA.'' Please remember to include the ICR number in 
any correspondence. The final rule will respond to any comments on the 
information collection requirements contained in this proposal.

D. Unfunded Mandates Reform Act and Executive Order 12875

    Pursuant to Title II of the Unfunded Mandates Reform Act of 1995 
(UMRA) (Pub. L. 104-4), EPA has determined that this action does not 
contain a Federal mandate that may result in expenditures of $100 
million or more for State, local, and tribal governments, in the 
aggregate, or the private sector in any one year. (The analysis of the 
costs associated with this action is referenced in Unit XI.A. of this 
preamble.) Therefore, this action is not subject to the requirements of 
sections 202 and 205 of the UMRA.

E. Executive Order 12898

    Pursuant to Executive Order 12898 (59 FR 7629, February 16, 1994), 
entitled ``Federal Actions to Address Environmental Justice in Minority 
Populations and Low-Income Populations,'' the Agency has considered 
environmental justice-related issues with regard to the potential 
impacts of this action on the environmental and health conditions in 
low-income and minority communities. Because many sources of HAP 
emissions are located near populations of lower socioeconomic status 
and with a higher proportion of minorities, the improved health 
database that will be generated by this action will help to protect 
these individuals and communities.

List of Subjects in 40 CFR Part 799

    Environmental protection, Chemicals, Hazardous substances, and 
Reporting and recordkeeping requirements.

    Dated: June 20, 1996.

Lynn R. Goldman,
Assistant Administrator for Prevention, Pesticides and Toxic 
Substances.

    Therefore, it is proposed that 40 CFR, chapter I, subchapter R, be 
amended as follows:

[[Page 33197]]

PART 799--[AMENDED]

    3. The authority citation for part 799 would continue to read as 
follows:

    Authority: 15 U.S.C. 2603, 2611, 2625.

    4. By adding Sec. 799.5053 to Subpart D of part 799 to read as 
follows:

Sec. 799.5053  Chemical testing requirements for hazardous air 
pollutants.

    (a) General testing provisions--(1) Identification of test 
substances. Table 1 in paragraph (a)(5) of this section identifies 
those chemical substances that shall be tested in accordance with this 
section. The purity of each test substance shall be 97 percent or 
greater unless otherwise specified.
    (2) Persons required to submit study plans, conduct tests, and 
submit data. All persons who manufacture (including those who import 
the substance or manufacture it as a byproduct) or intend to 
manufacture one or more of the substances listed in table 1 after the 
effective date listed in table 1 until the end of the reimbursement 
period shall submit letters of intent to conduct testing, submit study 
plans, conduct tests and submit data, or submit exemption applications, 
as specified in this section, subpart A of this part and parts 790 and 
792 of this chapter. Persons who manufacture or process these 
substances only as an impurity are not subject to these requirements. 
As explained in part 790 of this chapter, processors, small-quantity 
manufacturers, and manufacturers of small quantities of these 
substances solely for research and development purposes would become 
subject to these requirements only after notification in the Federal 
Register that no manufacturer had notified EPA of its intent to conduct 
testing.
    (3) Applicability of test guidelines. The guidelines and other test 
methods cited in table 1 in paragraph (a)(5) of this section are 
referenced here as they exist on the effective date listed in table 1 
for that specific test. Testing shall be conducted in accordance with 
the designated Series 870--Health Effects Test Guidelines and other 
test methods. This incorporation by reference was approved by the 
Director of the Federal Register in accordance with 5 U.S.C. 552(a) and 
1 CFR part 51. Copies may be obtained from the Public Docket and 
Freedom of Information Section, Field Operations Division (7506C), 
Office of Pesticide Programs, Environmental Protection Agency, 401 M 
St., SW., Washington, DC 20360. Copies may be inspected at the above 
address or at the Office of the Federal Register, 800 North Capitol 
Street, NW., suite 700, Washington, DC.
    (4) Interim reporting requirements. All testing requirements in 
this section are subject to the submission of interim progress reports 
every 6 months beginning 6 months after the effective date for any 
specific test listed in table 1 in paragraph (a)(5) of this section. 
The date for the submission of final reports is specified as the number 
of months after the effective date for the specific test listed in 
table 1.
    (5) Testing and reporting requirements. The substances identified 
by CAS Registry number and chemical name in the following table 1 shall 
be tested in accordance with the designated OPPTS Harmonized Guideline 
testing requirements and any additional requirements and limitations 
specified in the ``Specific requirements under this section'' column of 
table 1. The numbers and letters in this column refer to the specific 
requirements set forth in paragraph (b) of this section. Final reports 
shall be submitted by the deadlines indicated as the number of months 
after the effective date shown in table 1.

Pesticides and Ground Water State Management Plan Regulation

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of proposed rulemaking.

-----------------------------------------------------------------------

SUMMARY: This proposed rule implements a key component of the Agency's 
1991 Pesticides and Ground Water Strategy, and reflects many years of 
discussions and input from States and other stakeholders. Through the 
development and use of State Management Plans (SMPs), EPA is proposing 
to restrict the use of certain pesticides by providing States with the 
flexibility to protect the ground water in the most appropriate way for 
local conditions. This approach capitalizes on the most effective and 
efficient roles for State and Federal governments to collaborate in the 
protection of the nation's ground water resources. In this proposed 
rule, using the proposed SMP approach, EPA is proposing to restrict the 
legal sale and use of five pesticides that have been identified as 
either ``probable'' or ``possible'' human carcinogens--alachlor, 
atrazine, cyanazine, metolachlor, and simazine. Because of their 
potential to contaminate ground water, EPA has determined that these 
pesticides may cause unreasonable adverse effects on the environment in 
the absence of effective management measures provided by an SMP. The 
labels of these pesticides would be changed to require use in 
accordance with an EPA-approved SMP, after a period allowed for 
development and approval of these State plans. Incidentally, this 
proposed rule will also revise existing pesticide labeling regulations, 
in order to clarify general labeling requirements.

DATES: Written comments must be received on or before October 24, 1996.

I. Basis for Regulatory Action

A. Background

    Ground-water resources are of vital importance to the United 
States. The quality of these resources affects the health of its 
citizens, the integrity of many of its ecosystems, and the vigor of its 
economy. Ironically, the variety of human activities made possible by 
healthy ecosystems and abundant clean water also threatens the 
continued viability of these resources.
    Consequently, ground-water protection is a significant 
responsibility for EPA. In July 1991, the Agency set forth its ground-
water protection goals and guiding principles in ``Protecting

[[Page 33261]]

the Nation's Ground Water: EPA's Strategy for the 1990's'' (Ref. 11). 
The centerpiece of Agency ground-water protection efforts is 
development of Comprehensive State Ground Water Protection Programs 
(CSGWPPs). These programs are designed to integrate all State and 
Federal efforts to protect ground water, increasing the efficiency and 
effectiveness of State and Federal resources. The CSGWPPs also mark a 
new direction in Federal/State cooperation: EPA supports voluntary 
State initiatives to harmonize diverse ground-water protection 
activities. Since the use of pesticides contributes significantly to 
the problem of ground-water contamination, one of the Agency's first 
efforts in developing CSGWPPs is the establishment of State Management 
Plans (SMPs) for certain pesticides.
    A State Management Plan consists of 12 components that together:
    (a) Describe the State's ground-water protection philosophy and 
goals, its authority and its organizational and resource basis for 
fulfilling its commitment to manage the pesticide's use.
    (b) Detail the manner in which the State intends to carry out this 
commitment, using such measures as ground-water vulnerability 
assessments, ground-water monitoring, and direct management of 
pesticide use.
    (c) Establish the State's commitments to develop and implement 
these provisions through a process of public participation, to make 
pesticide users aware of State management measures and to monitor the 
effectiveness of the Plan through the development of meaningful 
measurements of environmental results.
    A pesticide State Management Plan is envisioned to be developed and 
implemented in the context of a State's CSGWPP, which outlines the 
State's overall ground-water protection approach. The additional 
benefits of coordinated implementation of a State's CSGWPP and its SMPs 
include: (1) More effective and consistent protection of the resource; 
(2) increased State control to target efforts towards highest priority 
protection; (3) more efficient use of limited program resources; and 
(4) reduced potential for ground-water protection activities to be at 
cross-purposes.
    While EPA regards the creation of SMPs as a significant step in 
protecting ground water from pesticides, EPA will continue to act to 
reduce the risk of ground-water contamination in its ongoing national 
pesticide registration and reregistration efforts. EPA will continue to 
consider specific label provisions for individual pesticide products as 
it screens both new and existing uses of pesticides. These may include 
general advisory language (warning users of a pesticide's potential to 
contaminate ground water and advising caution in the circumstances of 
its use) or more specific constraints on the conditions of use, as the 
evidence of contamination potential warrants. It may also include 
classifying pesticides for use only by or under the supervision of a 
certified applicator, under ``conventional'' restricted-use 
classification authority (see section D. of this Unit). These 
alternative risk-mitigation measures are also part of EPA's 
consideration in proposing pesticides for SMPs (see Unit II. of this 
preamble).
    The concept and development of pesticide SMPs is the direct 
outgrowth of extensive, collaborative work to produce a strategy for 
achieving ground-water protection by using and integrating all Federal 
and State pesticide regulatory authorities and resources. Beginning in 
1986, with major public workshops EPA created an interactive process 
with other Federal agencies, State agricultural, environment and health 
agencies, the private sector, environmentalists, farmers and other 
pesticide users, and ground-water experts. The States in particular 
have taken an active and constructive role in addressing pesticide and 
ground-water issues and have moved ahead with many of the management 
approaches ultimately endorsed by the final Agency strategy for 
pesticides and ground water.
    The Pesticides and Ground-Water Strategy (hereafter referred to as 
``the Strategy'') was issued October 31, 1991 (Ref. 12). The Strategy 
describes the Agency's goals, policies, management programs, and 
regulatory approaches for protecting the nation's ground-water 
resources from risks of contamination by pesticides. The Strategy, and 
the 1988 proposed Strategy, characterize the breadth and seriousness of 
the potential problem of pesticides in ground water and the need for 
coordinated regulatory and nonregulatory initiatives to protect the 
resource (Ref. 7). Those interested in a more detailed discussion of 
the history, purpose, objectives, and policy are referred to the 
Strategy itself.

B. Goal

    The Strategy articulated the Agency's goal for pesticides and 
ground water. In summary, the goal:

    is to prevent contamination of ground water resources resulting 
from the normal, registered use of pesticides that would cause 
unreasonable risks to human health and the environment by taking 
appropriate actions where such risks may occur. (Ref. 12, p 9, see 
also pp ES 6-7; emphasis added)
    This goal highlights two important elements of EPA's pesticide and 
ground-water policy: pollution prevention and local action.
    Delaying action until ground-water contamination occurs at 
significant levels and with a frequency sufficient to cause immediate 
concern is costly, and ultimately counterproductive. ``[G]round-water 
cleanup is extremely costly, and usually difficult and in some cases 
impossible to achieve and demonstrate'' (Ref. 12, p. 10; also, Ref. 11, 
p 5). In some cases, actual ground-water contamination may be virtually 
irreversible. Allowing contamination to reach a level that presents an 
immediate threat to human health or the environment forecloses 
prevention and necessitates remediation. Remediation is more costly, as 
well as more dangerous, than prudent action to anticipate and prevent 
harm.
    The second element of the Agency goal is local action. Taking 
action locally, ``where such risks may occur,'' takes into account the 
highly variable factors affecting the potential for ground-water 
contamination. ``Ground water is a uniquely local resource due to the 
ease with which small sources can affect it, and the impact that use 
and hydrologic characteristics can have on its quality'' (Ref. 11).
    There are several factors which generally influence whether 
pesticides will contaminate ground water: (1) The properties of the 
chemical itself (e.g., solubility in water, persistence, and mobility 
in the subsurface environment); (2) the characteristics of the site of 
use (e.g., soil type, depth to ground water, temperature, rainfall, and 
site-specific hydrological factors collectively denoted by the term, 
``sensitivity''); (3) application practices, (e.g., the amount of 
pesticide per application, the frequency and method of applications); 
and (4) other agronomic practices associated with the pesticide use 
(e.g., irrigation or tillage practices).
    The Agency believes that, as a general matter, the best method for 
addressing differences in sensitivity throughout the country is to 
tailor prevention measures in a given area to reflect the vulnerability 
of local ground water to contamination. This approach minimizes the 
complementary risks of over-regulating where ground water is not 
particularly vulnerable to contamination and of underprotecting highly 
vulnerable areas which might result from a solely ``national'' 
regulatory approach. It is expected to

[[Page 33262]]

result in an efficient regulation of pesticide use that will satisfy 
the pre-eminent objective of reducing or eliminating unreasonable risk 
with respect to ground water.
    The Agency has further concluded that for pesticides which may pose 
an unreasonable risk, the States can appropriately take the lead in 
preventing unreasonable risk and protecting ground water through the 
management of pesticide use. State management of use can be based on 
local relative vulnerability of the ground-water resource, and where 
necessary, its use and value. A lead role for the States, consistent 
with overall Agency ground-water protection principles, acknowledges 
the traditional primacy of States in the management and protection of 
ground water as a natural resource; makes best use of expertise at the 
State level in local hydrogeology, soils, agronomic practices, climate, 
and pesticide use; and takes advantage of State and local understanding 
of population and land use trends that help to define the future use of 
ground-water resources.

C. SMP Start-up

    State participation in pesticide-use management is a significant 
new step for many States, requiring substantial preparation. EPA has 
assisted this start-up in several ways, described more fully in the 
Strategy.
    1. Since 1990, EPA has provided funds to States to help develop 
``generic'' SMPs. In these ``generic'' SMPs, States prepare for 
development of pesticide-specific requirements by providing basic, 
generalized information for each of the required components of a 
pesticide-specific SMP. Generic SMPs give States an early opportunity 
to consider how they will design Plan components and build the capacity 
to implement them. Since Generic Plans have no legal force, EPA does 
not ``approve'' them, in the sense of conferring legal authority upon 
them; rather, States will submit Generic SMPs for review, comment and 
concurrence. Fifty-seven States and territories with primary 
enforcement authority for FIFRA use violations, as well as two Indian 
tribal authorities, have received funds and are proceeding with 
development of the generic SMPs. EPA has provided $35 million in grants 
for this purpose in the Fiscal Years 1990 to 1996. By June 1995, all 50 
States had developed and submitted draft Generic Plans to EPA regions 
for early review and comment.
    2. EPA published a Guidance for Pesticides and Ground Water State 
Management Plans with two appendices in December 1993 (Ref. 18, 
hereafter referred to as the Guidance). It provides practical 
instruction on how to develop both Generic and pesticide-specific SMPs. 
Much of the contents of the Guidance and the first Appendix anticipates 
the contents of today's proposed rule (see Unit II.C. of this 
preamble). These documents should be referred to for a more complete 
description of how EPA envisions SMPs will be developed, and what EPA 
envisions the level of protection will be.
    3. As mentioned at the outset of this Unit, pesticide-specific SMPs 
are intended to operate as an integral part of CSGWPPs. Likewise, 
pesticide and ground-water protection measures tie into other EPA 
programs and grants dedicated to ground-water protection. Among the 
many related activities are: (a) The non-point source program under 
section 319 of the Clean Water Act; (b) Coastal Zone non-point source 
measures mandated by the Coastal Zone Management Act as amended in 
1990; (c) the emerging ``watershed protection approach'' for 
implementing the Agency's Clean Water Act activities; (d) Wellhead 
Protection Programs and other drinking-water source-protection 
initiatives under the Safe Drinking Water Act (SDWA); and (e) Public 
Water System regulatory programs under SDWA, in particular, the 
establishment of Maximum Contaminant Levels (MCLs) and monitoring 
requirements for a variety of contaminants (including the five 
pesticides subject to today's proposed rule). For example, an SMP 
designed to deal with pesticide contamination risks could be integrated 
with a Well Head Protection Program in a rural community where 
pesticide use in nearby agricultural areas posed a threat to well field 
re-charge areas. The SMP would provide Federal and State authorities 
for pesticide regulation to complement and interact with the State's 
other water quality protection authorities to help achieve the goal of 
the Well Head Protection Program. A more detailed description of the 
variety of interlocking programs is provided in an October 1992 
document prepared by EPA's Office of Pesticide Programs (OPP), 
``Integrating EPA's Agriculture and Water Grant Programs.''
    In addition, the Strategy detailed a variety of related Federal 
non-regulatory activities, including U.S. Department of Agriculture 
(USDA) research and the ongoing activities of the U.S. Geological 
Survey (USGS), as well as the connection between ground-water 
protection and the Agency's ongoing pesticide regulatory initiatives, 
such as encouraging the development of reduced-risk pesticides.

D. Statutory Authority

    As a general matter, pesticides may not be sold, distributed, or 
used in the United States unless they are registered by EPA [FIFRA 
section 3(a)]. The standard for granting and maintaining a registration 
is found in FIFRA section 3(c)(5). Among other things, this section 
requires that the pesticide will perform its intended function without 
causing unreasonable adverse effects on the environment and that, when 
used in accordance with widespread and commonly recognized practice, 
will not cause unreasonable effects on the environment.
    Further, FIFRA section 3(d) gives EPA authority to classify a 
pesticide for restricted use if EPA finds its use may cause 
unreasonable adverse effects on the environment. Specifically, FIFRA 
section 3 (d)(1)(C) [7 U.S.C. 136a(d)(1)(C)], provides:

    If the Administrator determines that the pesticide, when applied 
in accordance with its directions for use, warnings and cautions and 
for the uses for which it is registered, or for one or more such 
uses, or in accordance with widespread and commonly accepted 
practice, may generally cause, without additional regulatory 
restrictions, unreasonable adverse effects on the environment, 
including injury to the applicator, he shall classify the pesticide, 
or particular use or uses to which the determination applies, for 
restricted use.

    In the event the Administrator makes such a determination, ``the 
pesticide shall be applied ... only by or under the direct supervision 
of a certified applicator, or subject to such other restrictions as the 
Administrator may provide by regulation'' (FIFRA section 
3(d)(1)(C)(ii); emphasis added). An EPA-approved SMP would be such an 
``other restriction.''
    The basis for determining whether a pesticide warrants the 
``additional regulatory restrictions'' referred to in section 
3(d)(1)(C), is finding that the pesticide ``may generally cause ... 
unreasonable adverse effects ...'' without such additional 
restrictions. FIFRA section 2(bb) defines unreasonable adverse effects 
as ``any unreasonable risk to man or the environment, taking into 
account the economic, social and environmental costs and benefits of 
the use of any pesticide.'' Thus, one of the critical aspects of 
determining whether additional regulatory restrictions are necessary is 
an evaluation of the risks and benefits of the pesticide use. However, 
in finding a pesticide may cause unreasonable adverse effects, EPA will 
consider these risks and benefits in a manner that takes into account 
the considerable uncertainty surrounding both. Unit IV. of this 
preamble, as well

[[Page 33263]]

as the Regulatory Impact Analysis prepared for this proposed rule, 
describes the relative risks and benefits associated with the five 
pesticides proposed to be subject to SMPs, as well as the costs and 
benefits of State Management Plans as a regulatory measure.
    Any restrictions imposed under FIFRA section 3(d) authority are 
fully enforceable under FIFRA. Section 12 (a)(2) of FIFRA specifically 
provides that it shall be unlawful (in subparagraph (F)):

    to distribute or sell, or make available for use, or to use, any 
registered pesticide classified for restricted use for some or all 
purposes other than in accordance with section 3(d) and any 
regulations thereunder.

Thus, once this rulemaking is final and EPA has approved the 
requirements and specifications that constitute a SMP, that SMP will be 
fully enforceable by Federal authorities. EPA will also require 
registrants to incorporate the restriction to use a pesticide according 
to the provisions of an EPA-approved State Plan as part of that 
pesticide's labeling. Thus SMP requirements would also be federally 
enforceable pursuant to section 12 (a)(2)(G), which makes it illegal 
``to use any registered pesticide in a manner inconsistent with its 
labeling.''

II. Process for Selecting Pesticides for Restriction under SMPs

A. Determining Potential to Contaminate Ground Water

    As described in Unit I. of this preamble, the Agency's goal for 
ground-water protection is to prevent contamination that would cause 
unreasonable risks. Prevention entails the need to act in anticipation 
of future environmental harm to ensure that this harm does not occur.
    There are many uncertainties that limit the ability to quantify 
risks and benefits to any reasonable degree of accuracy. These stem in 
part from the circumstances pertaining to ground-water risks, and are 
discussed further in Unit IV. of this preamble. These and other 
impediments to national-level risk-benefit analysis were addressed in 
the development of the Strategy, and in fact were instrumental in the 
decision to favor the SMP approach in addressing serious pesticide 
ground-water risks. Prescribing SMPs for individual pesticides fits 
under EPA's regulatory authority to regulate beneficial but potentially 
risky substances well before the onset of unreasonable adverse effects. 
It also accommodates the uncertainties and variations which 
characterize groundwater risk assessment.
    This judgement will be made consistent with the Agency's current 
regulatory procedures for classifying pesticides for restricted use. 
These procedures are contained in 40 CFR part 152, subpart I. They 
provide for EPA to impose restrictions other than limiting use to 
certified applicators if the Agency determines that:

    (a) Without such restrictions, the product when used in 
accordance with warnings, cautions and directions for use or in 
accordance with widespread and commonly recognized practices of use 
may cause unreasonable adverse effects on the environment; and
    (b) The decrease in risks as a result of restricted use would 
exceed the decrease in benefits as a result of restricted use. (40 
CFR 152.171)

Subpart I also provides for restricting use to certified applicators 
and for other types of future restrictions, as authorized by FIFRA 
section 3(d)(1)(C). Unit III. of this preamble explains in further 
detail the distinction between such new ``other regulatory 
restrictions'' as this SMP requirement and the conventional restricted 
use of application only by or under the supervision of a certified 
applicator.
    EPA will make such a determination to subject a pesticide to the 
requirements of an SMP through a weight of evidence analysis, taking 
into account the economic, social and environmental costs and benefits 
of the pesticide's use.
    The first step in this weight-of-evidence approach is to 
characterize a pesticide's potential to contaminate ground water. 
Direct evidence of a pesticide's contamination potential includes its 
physical-chemical properties (e.g., leaching potential) and the 
circumstances, frequency and concentrations of known occurrence in 
ground water. In addition to the direct evidence of contamination 
potential, EPA will take into account information about use patterns 
and practices which may supplement the more direct evidence of 
contamination potential. Specifically, EPA will also consider: (a) The 
crops and sites on which a pesticide is registered for use; (b) the 
volume of pesticide used (on specific sites or crops, or in total) and 
the extent of the pesticide's use (in terms of rates and/or number of 
acres treated); and (c) the methods, timing, and rates of application 
of a pesticide.
    EPA will also take into account the potential of any of a 
pesticide's by-products, metabolites or degradates, or any other 
component of a product associated with the pesticide, to reach ground 
water or to cause an adverse effect thereby, to the extent such 
substances have been identified and information about their potentials 
are known.

B. Determining Potential Risk

    The second step is to compare the pesticide's potential to 
contaminate ground water to an indicator of unreasonable risk. In 
theory, a pesticide may have a ``potential to contaminate ground 
water'' but not an associated significant ``potential to cause adverse 
effects.'' The Ground-Water Reference Point is an important tool in 
determining whether this association exists. Ground-Water Reference 
Points are numerical indicators of the toxicity of a substance 
established by EPA, based on test data and other reliable health 
effects information. The concept of Ground-Water Reference Points was 
explicated in the July 1991 Protecting the Nation's Ground Water: EPA's 
Strategy for the 1990's (Ref. 11; in Part D, ``Agency Policy on EPA's 
Use of Quality Standards in Ground-Water Prevention and Remediation 
Activities'') and echoed in the Strategy (Ref. 12). Pursuant to these 
policies, EPA will use as reference points for specific substances any 
of the following: (1) Maximum Contaminant Levels (MCLs) established 
under the Safe Drinking Water Act, or (2) Health Advisories (where MCLs 
are not available for a substance), or (3) Water Quality Standards 
(where the concern is adverse effects to ecosystems affected by closely 
hydrologically linked surface waters) under the Clean Water Act. If 
such numbers are not available, reference points may be derived from 
the health effects literature where appropriate. In certain cases, the 
Agency policy (cited above) provides that Maximum Contaminant Level 
Goals (MCLGs) under the Safe Drinking Water Act may be used in order to 
comply with Federal statutory requirements; however, MCLGs are unlikely 
to be used in the context of any regulatory action the Agency might 
take under FIFRA.
    In protecting ground water, the Agency takes the reference point as 
a benchmark that defines the failure of currently-implemented 
preventive measures (c.f., Ref. 11, p. 31: ``Reaching the ... 
appropriate reference point would be considered a failure of 
prevention.''). In the context of pesticides and ground water, a 
detection at or above the level established as the appropriate Ground-
Water Reference Point for a pesticide ingredient would be considered a 
failure of measures to prevent unreasonable risk to human health or the 
environment associated with that ingredient. Known

[[Page 33264]]

or predicted levels of contamination can be compared to these reference 
points in order to gauge the relative risk of adverse effects. 
Reference points provide a means by which the Agency may assess and 
take into account the toxicity of ground-water contaminants, and 
thereby the implicit level of hazard and risk posed by particular 
contamination levels. Given the uncertainties regarding: (1) The actual 
level and extent of pesticide contamination in ground water; (2) the 
nature and degree of human exposure associated with such contamination; 
(3) either the levels or the mechanisms of pesticide occurrence that 
may affect ecosystems, habitats, or non-target biological organisms; 
and (4) the anticipated future levels of occurrence, exposure and 
associated hazard, it is problematic to make direct estimates of 
exposure, and hence estimates of risk, with satisfactory accuracy. 
Therefore, use of reference points to gauge the relative seriousness of 
detected pesticide contamination serves as a useful surrogate to direct 
estimates of exposure and risk.
    It is theoretically possible to determine that a pesticide has the 
potential to contaminate ground water, but that it is unlikely to cause 
adverse effects. In practice, however, this distinction can often be 
difficult to sustain with reasonable certainty. First, there is often 
significant uncertainty about the levels and extent of current 
contamination. Ground water is not systematically monitored across the 
country. Ground waters susceptible to contamination by pesticides vary 
significantly in character, limiting the ability to generalize beyond 
ground-water monitoring sites. For ground water, models are not 
sufficiently reliable to predict future contamination. Second, any 
contamination of ground-water resources represents some tangible damage 
to its value as a resource to present, and especially future, 
generations. The Agency's pollution prevention philosophy clearly 
states the Agency's interest in protecting the resource from 
impairment. Hence, the Agency included in its Reference Point policy 
that, as a matter of policy (Ref. 11):

    Detection of a percentage of the reference point at an 
appropriate monitoring location would then be used to trigger 
consideration of additional action (e.g., additional monitoring, 
restricting, limiting use or banning the use of a pesticide).

As a matter of prudence, therefore, the Agency considers the ability to 
reach ground water, as indicated by physical and chemical properties, 
and detections at any level to be evidence of some potential to reach 
ground water at an unacceptable level.

C. Determining Appropriate Regulatory Action

    After characterizing the pesticide's ground-water contamination 
potential and its associated health and environmental risk, EPA next 
considers the adequacy of current labeling safeguards. The Strategy 
describes this step (Ref. 12):

    If EPA has reasonable assurance from the evidence of a 
particular chemical's contamination potential that it would not 
cause `unreasonable adverse effects on the environment' if used in 
accordance with the requirements of the label or under the 
conditions of restricted use [to certified applicators], then 
...those national-level management measures [would be] the only 
measures necessary.

    However, if EPA cannot conclude from the available evidence that 
these measures would sufficiently reduce the risk of ground-water 
contamination, it could pursue either an approved SMP, ... or 
national cancellation if State Management Plans would not be 
adequate to prevent risks.

A judgement on the need for State management measures depends on the 
Agency's confidence in the effectiveness and efficacy of these uniform 
national labeling instructions relative to the protection anticipated 
from SMPs, present use practices and patterns, existing State risk-
mitigation measures and other prospective Federal regulatory actions, 
including label changes and restricting use to certified applicators. 
When EPA has adequate confidence in the efficacy of such measures, it 
will conclude SMPs are unnecessary. The decision to prescribe SMPs is a 
judgement that national labeling limitations likely will not prevent 
the realization of a pesticide's ground-water contamination potential.
    In considering whether to prescribe an SMP for a pesticide, EPA 
evaluates the benefits of continued pesticide use under the provisions 
of an SMP. The assessment of whether the reduced risk of ground-water 
contamination might justify the social and economic costs of the SMP is 
documented in a Regulatory Impact Assessment. The costs considered 
include both the expense of developing and implementing SMPs (e.g., 
direct costs) as well as the costs of foregone benefits (e.g., indirect 
costs). Indirect costs may include more expensive pest-control 
substitutes and the economic loss associated with less pest control. 
The Agency decides to establish the SMP restriction upon a reasoned 
determination that the benefits of regulatory action justify its costs, 
recognizing that some costs and benefits are difficult to quantify.
    Finally, EPA also considers whether it is likely to take other, 
more stringent regulatory action such as cancellation of major products 
and/or uses of a particular pesticide. For instance, the Agency might 
conclude that a pesticide in Special Review poses an unreasonable risk 
for reasons different from and in addition to ground-water concerns, so 
that only cancellation of major products and/or uses would be 
appropriate. In that case, EPA would be inclined not to require the 
States to develop SMPs to manage uses that will soon be prohibited. On 
the other hand, EPA may both start a Special Review of a pesticide and 
propose the same pesticide for SMPs via rule making. There may be a 
need to provide the increased level of ground-water protection afforded 
by State Plans while the Special Review is conducted. As the Strategy 
explained, EPA may also use its cancellation authorities under FIFRA 
section 6 to establish SMPs. There are many possible outcomes of a 
Special Review besides the more stringent measure of cancellation. For 
example, the Agency is addressing the ground-water contamination 
potential of the pesticide aldicarb through a Special Review instituted 
in 1984, and thus is not including it in this proposed rule. EPA sees 
no inconsistency in pursuing both this proposed rule and the new 
Special Review for the triazines, initiated in November 1994.

D. Selection of Pesticides for Today's Rule

    The Agency has selected five pesticides for regulation under SMPs: 
atrazine, simazine, cyanazine, alachlor and metolachlor. In selecting 
these five, the Agency evaluated the ground-water contamination 
potentials, hazards and uses of 20 currently registered pesticides that 
have been reported to occur most frequently in ground water, according 
to the available data compiled by EPA's Office of Pesticide Programs 
(Ref. 15) (see Table 1). This included the pesticide aldicarb, which 
was not considered for this proposed rule in light of its ongoing 
Special Review.

                                            Oxamyl                      
                                            Promoton

                                            2,4-D                       
------------------------------------------------------------------------

    The five pesticides selected for this proposed rule, stand apart in 
the breadth, frequency, and magnitude of ground-water contamination. 
While Unit IV. of this preamble goes into the evidence in greater 
detail, each has been detected hundreds of times in many States. Each 
has been detected at levels exceeding their corresponding reference 
points in multiple locations or times, clearly exhibiting a capacity to 
contaminate ground water at concentrations exceeding health-based 
standards. All five are also associated with serious and irreversible 
toxicological effects, including carcinogenicity. One (alachlor) was 
classified as a B2 (probable human) carcinogen by EPA, but is now 
considered to be not classified pending further review of scientific 
issues; the remaining four have been classified as C (possible human) 
carcinogens. These classifications are under review, as discussed later 
in this document.
    All five are broad-spectrum herbicides with extensive agricultural 
uses. These similarities of use suggest that these five can be 
regulated together as a cluster. Since all raise significant ground-
water concerns, dealing with them together also helps prevent creating 
unintended incentives to substitute ones under State-management 
constraints for those less stringently regulated. Analytic methods for 
ground-water monitoring of these compounds are available and in 
widespread use around the country. This fact, combined with the 
commonalities of use practices, will make it easier for States to 
develop coordinated monitoring programs for these five as a group.
    Among the other candidates, several are known to have occurred in 
concentrations exceeding an MCL or Health Advisory Levels, but not as 
frequently as the pesticides selected. Furthermore, previous regulatory 
restrictions on use can be considered to have significantly reduced the 
risks of ground-water contamination for some of these candidates. One 
example is carbofuran, which has been detected over 4,100 times from 
1980-1990 in 11 States, with 73 of those detections at levels over the 
current MCL of 40 micrograms per liter (g/l) (Ref. 15). 
However, the vast preponderance of those detections (and all but one of 
those above the MCL) occurred in Suffolk County, New York, where all 
carbofuran use was banned in 1987. In addition, granular carbofuran 
products (which represent most of the chemical's prior use) have been 
phased out except for a few specialty uses. Other candidates on the 
list have had frequent occurrence in ground water, but neither as 
widely nor as frequently at high concentrations, as the five selected 
for this proposed rule.
    EPA is proposing in today's rule to regulate those pesticides which 
in its judgement pose the greatest threat to ground water. The number 
of chemicals involved - five is a manageable number to ask States to 
manage; EPA hopes to facilitate State participation by designating only 
a manageable number of pesticides for SMPs at the outset.

III. State Management Plan Specifications, Development and Approval 
Procedure

A. Introduction

    This document proposes adding a new subpart J to 40 CFR part 152, 
specifying SMPs as an ``other regulatory restriction'' authorized by 
FIFRA section 3(d).
    Much of what SMPs will be and how they will work has been discussed 
in previous documents (e.g., the Strategy). In particular, this Unit of 
today's proposal follows closely the contents of EPA's Guidance (Ref. 
18). The Guidance (with two Appendices) describes in detail EPA's 
expectations about the contents of an acceptable SMP, as well as the 
criteria and procedures EPA Regional Offices will use in deciding 
whether to accept or reject State Plans. Readers seeking more details 
on these subjects should refer to the Guidance. EPA intends generally 
to use the Guidance in reviewing State submissions, and to follow the 
provisions of the Guidance's Appendix A in review, approval, 
evaluation, amendment and (where necessary) revocation of State 
Management Plans. However, the Guidance is subject to revision; for 
example, the Agency fully expects to supplement the existing guidance 
in light of comments on today's proposed rule.
    As explained in Unit I. of this preamble, State Management Plans 
are intended to complement CSGWPPs; as such, SMPs can be regarded as a 
program-specific subset of a CSGWPP. However, the requirements proposed 
here are specific to pesticide regulation under FIFRA, and so are 
somewhat more detailed than what is required under a completed CSGWPP 
as described in the 1992 Guidance. For example, under the Prevention 
component of SMPs (c.f., section 2(g) of this Unit, below), specific 
best management practices need to be listed and described for each 
pesticide. To meet SMP requirements efficiently, a State can 
extensively refer to portions of its CSGWPP, but the State also will 
need to build on the basic policies and approaches of the Comprehensive 
Program. Similarly, in the development of its CSGWPP, a State should 
ensure that aspects relevant to pesticides management are consistent 
with the requirements of an SMP. Because development of SMPs and 
CSGWPPs will occur at the same time in most States, the development of 
SMPs should not wait until a CSGWPP is completed. The Guidance on 
Pesticides and Ground Water State Management Plans describes the 
interrelationships of SMPs and CSGWPPs in greater detail (Ref. 18).
    Several definitions of terms, applicable to this new subpart J, are 
proposed, in the new 40 CFR 152.183. The term ``ground water reference 
point'' (as discussed in Unit II.B. of this preamble) is defined for 
purposes of specifying the contents of an approveable SMP, and is 
consistent with the Agency's reference point policy. Two other terms 
are defined simply to facilitate reference to frequently referred 
concepts. The term ``Plan'' is defined as a shorthand term to refer to 
the SMP which is the subject of subpart J. In addition, ``State'' 
itself is defined to mean not only the 50 States, but also Puerto Rico, 
the District of Columbia, Guam and other territories and jurisdictions, 
plus Indian lands. This last category will be discussed in more detail 
below.
    The proposed restriction itself is relatively simple and 
straightforward: a pesticide or pesticide product that is classified in 
this or a subsequent rulemaking may only be used in accordance with the 
provisions and requirements of an Agency-approved SMP, as of a specific 
date to be established by the rule. At that time, that pesticide or 
pesticide product may not be sold or used within a State without an 
Agency-approved Plan. These restrictions are the meaning of references 
to a pesticide being ``under,''

[[Page 33266]]

``subject to,'' ``classified for,'' ``designated for,'' or ``listed 
for'' SMPs.
    The proposed ``restriction'' section (40 CFR 152.185) also contains 
some requirements on the registrants to amend the labeling of the 
products subject to SMPs, in order to notify users that use is now 
subject to the conditions of an approved SMP. Labeling provisions will 
be discussed in more detail in Unit III.G. of this preamble. Since the 
direct effect of this rule would be to limit the sale and use of the 
pesticide to States with approved SMPs, it would affect distribution 
and sale of these pesticides. Thus, distribution and sale of the 
pesticides subject to this rule with improper or obsolete labeling will 
be prohibited after the effective date of the rule.
    The ``restriction'' will entail a specific label statement, as 
follows:

    For use only in accordance with an EPA-approved State Management 
Plan (SMP) for ground-water protection. Sale and use are prohibited 
in States that do not have an EPA-approved State Management Plan.

    This restriction would be effective 33 months after promulgation of 
this proposed rule as final. This period is designed to allow States to 
develop the Plans, EPA to review them, and registrants to change 
labels. Comments on the proper time frame for the effective date of 
SMPs are welcome; the Agency would especially value specific 
explanations of any procedural or legal constraints that States face in 
developing SMPs.
    This restriction is a classification for restricted use pursuant to 
FIFRA section 3(d), but the classification does not automatically 
entail the restriction of use ``only by or under the supervision of a 
certified applicator.'' Conventionally, ``restricted use'' has come to 
mean exclusively this restriction to use by certified applicators, as 
specified in the Act. This disregards the possibility of more flexible 
meanings for ``other regulatory restrictions.'' Nonetheless, three of 
the five pesticides being proposed for SMPs today are already 
classified for restricted use in the conventional sense (one of which, 
atrazine, is explicitly classified for ground-water contamination 
concerns). Moreover, all five meet EPA's proposed criteria for 
considering a pesticide for restricted use classification because of 
ground-water concerns, as proposed May 13, 1991 (56 FR 22076). 
Therefore, EPA is interested in receiving comment on whether the Agency 
should simultaneously classify all of these pesticides for 
``conventional'' restricted use due to ground-water concerns when it 
determines that they require an SMP. Such a procedure would oblige EPA 
to make a finding that the pesticide in question meets the criteria of 
40 CFR 152.170, but such a finding could be made in this rulemaking for 
SMPs, since the Agency has laid out in this proposed rule an analysis 
of risks and benefits for these pesticides that could justify such a 
determination. EPA believes that such findings would be facilitated by 
the establishment of final ground-water restricted-use criteria.
    The provisions, specifications, and requirements of these EPA-
required State Plans do not replace, but add to existing or future 
national-level conditions of use, such as label directions for use, 
restrictions or precautions. Unless specifically provided, either in a 
final rule or in some action to amend a product's label, nothing in an 
SMP will supersede a national-level condition of registration. States 
may not supplant, override, or nullify a Federal label provision in 
developing an SMP proposal, or in implementing an EPA-approved SMP.

B. Overview of Application Approval Process

    Section 152.187 of the proposed new subpart J sets out the 
procedures by which a State may submit, and EPA would approve, an SMP 
for each of the five pesticides covered in today's proposed rule.
    1. State submissions. While Sec. 152.187 provides that a State may 
submit a proposed Plan at any time, Sec. 152.187 prohibits use of a 
pesticide or pesticides in question in States without an EPA-approved 
Plan after the effective date for the regulation. For practical 
purposes, then, a State would need an approved SMP in place by the date 
33 months after the promulgation of the final rule, the proposed 
effective date of this regulation, in order that sale and use of the 
pesticide(s) in question continue within the State's borders.
    States that intend to develop SMPs for any or all of the five 
pesticides in today's proposed rule will be required to submit proposed 
Plans for official EPA review within 2 years of the promulgation date. 
This would allow 9 months for EPA to review, consult and decide on 
approval of the State's submittal, and for States to prepare the 
implementation of the approved SMP on the effective date of the Federal 
restriction. States submitting Plans later than 2 years after 
promulgation of the rule would run a substantial risk that EPA will be 
unable to perform its review, and approve the Plan before the effective 
date of the regulation to enable the States to implement it at that 
time. As noted above, EPA welcomes comments on the feasibility of this 
proposed schedule.
    In the interest of encouraging use of electronic information 
technology, EPA is proposing to require States submit their SMPs 
electronically (e.g., by disk) in an appropriate word processing 
format.
    EPA would encourage States to submit SMPs for these five pesticides 
together, as a single package. While the SMP requirement imposed by 
this proposed regulation would be a condition of registration for each 
pesticide individually, EPA believes it is proper for States to combine 
their SMP submittals, at least for the five pesticides subject to this 
proposed rule. Combined submittals should be a resource savings for 
both EPA and the States, since these five pesticides are similar in use 
patterns and analytic methodologies. For practical purposes, large 
portions of Plans for individual pesticides can be expected to be 
substantially identical to each other (e.g., vulnerability assessments, 
monitoring sites), beyond the shared ``generic'' elements like 
philosophy and goals, legal authority, and resources. EPA would 
evaluate the adequacy of such joint SMPs together, as a cohesive multi-
chemical Plan. However, EPA would retain the ability to selectively 
approve or disapprove Plans for individual pesticides covered by such a 
multi-chemical Plan, based on a judgement that the combined Plan is 
inadequate in some respect.
    2. EPA review, approval, or disapproval. EPA intends to be flexible 
in its review of SMPs, recognizing that different approaches and 
philosophies can obtain the same environmental results. States will 
need to tailor prevention measures to local ground-water vulnerability, 
current and future use and value of ground water, pesticide use and 
agronomic characteristics and institutional characteristics. Appendix A 
of the Guidance describes in greater detail the internal process, 
including the general roles and responsibilities of EPA Headquarters 
and Regional Offices.
    While the regulation specifies that ``the Administrator'' will make 
the determination whether a State submission is acceptable, it is the 
Agency's intention to delegate this authority to the Regional 
Administrator when the regulation is promulgated. The proposal as 
drafted requires States to submit their Plans to the appropriate EPA 
regional office. As the Guidance (Appendix A, p. 2-1) makes clear, EPA 
believes the Regional Administrator is the proper official to make this 
determination, given the proximity to the States and their particular

[[Page 33267]]

circumstances. In delegating approval authority to the Regional 
Administrator, EPA anticipates that only a limited Agency Headquarters 
role will be necessary. Headquarters will help assure overall national 
consistency among Regions by providing a forum to, for example, air 
issues which Regions believe may need additional clarification. It is 
EPA's assumption that such consultation will be particularly helpful in 
the beginning of SMP development and implementation; therefore, the 
Agency has established a regular schedule of regional/HQ consultation 
to facilitate regional review of initial Generic and pesticide-specific 
SMPs. After promulgation of the rule, Headquarters will continue to 
provide specific national policy guidance and technical assistance as 
the regions require.
    The Guidance, in Appendix A (Chapters 2-4), envisions a two-step 
process for EPA review and approval or disapproval of proposed State 
Plans. The first step, a completeness review, is to ensure that the 
State has addressed all 12 components of an SMP, pursuant to the 
requirements set forth in Sec. 152.190 of the proposed new subpart J. 
The second step, content review, is a more thorough examination of the 
SMP to determine whether it adequately addresses each of the 12 
components of an SMP and therefore is likely to protect the ground-
water resource from pesticide contamination.
    As expressed in Appendix A of the Guidance, EPA expects that during 
the review and approval process there will be close and frequent 
interaction between the regions and the States to reach a mutually 
acceptable final Plan.
    However, Sec. 152.187(d) of the proposed rule does provide for the 
possibility of EPA disapproval of a State-submitted Plan. In content 
this section parallels the procedure EPA is proposing to revoke 
previously-approved SMPs (see Sec. 152.195, discussed in F., below and 
Appendix A).
    If the Regional review concludes that the State Plan is inadequate, 
either in completeness or in content, the Regional Lead Office would 
work with the State to address concerns before the effective date of 
the SMP restriction to prevent interruption of sale and use of the 
subject pesticide in the State. If the State fails to satisfy the 
Agency's concerns, the sale and use of the pesticide would be 
prohibited in the absence of EPA approval.
    In the event the Region and State fail to reach agreement on an 
SMP, the Regional Administrator will notify the State Liaison and the 
officials directing the key State agencies in writing, indicating that 
EPA will not approve the State's Plan in its present form. This letter 
of notification will provide the State a last opportunity to satisfy 
the Regional Administrator's concerns and/or persuade the Regional 
Administrator that the State's proposal is adequate.
    Even formal disapproval would not represent the end of a State's 
opportunity to develop a Plan. Since proposed Sec. 152.187 provides 
that States may submit an SMP for regional consideration ``at any 
time,'' a State whose Plan or Plans have been disapproved would be free 
to revise and re-submit the Plan at its discretion.
    Whether the Regional Administrator approves or disapproves a 
State's Plan, he or she will publish a formal notice of the decision in 
the Federal Register. As proposed, notice of the final decision to 
approve or disapprove is the only formal notice provided for by this 
regulation. In proposing this rule, EPA considered, but decided 
against, providing for formal public notice and opportunity for comment 
on the Regional Administrator's review of each State Plan. In making 
this decision, EPA in part relies on the requirement that the States 
must provide for public participation in SMP development to obtain EPA 
approval of such a Plan (see proposed Sec. 152.190(j) of the regulatory 
text).
    With this proposal, therefore, EPA states its belief that there is 
sufficient evidence of unreasonable adverse effects on the environment, 
within the meaning of FIFRA section 3(d)(1)(C)(ii), to warrant adoption 
of SMP's as an additional regulatory restriction. The Agency's basis 
for this proposed determination is set out in Unit IV. of this 
preamble.
    Today's proposal, if finalized, would establish that there may be 
unreasonable adverse effects without the additional regulatory 
restriction of an SMP. The question then remains as to whether the 
particular Plan is adequate to prevent unreasonable adverse effects on 
the environment, or whether it is overly restrictive, i.e. whether a 
particular SMP adequately takes into account the social and 
environmental costs and benefits of the use of the pesticide. The State 
would consequently be able to develop and justify its SMP pursuant to 
the unreasonable adverse effects standard, as well as against the 
specific programmatic elements set out in this proposed rule.
    EPA is also proposing procedures to assure adequate notice and 
opportunity to comment on whether a particular SMP satisfies the 
unreasonable adverse effects standard and the specific programmatic 
elements. Thus, States would be required to provide notice and 
opportunity to comment on these issues as part of its SMP 
implementation procedures. The State would have to respond to any 
comments and to justify its chosen approach in the administrative 
record developed to support the SMP. In deciding whether to approve or 
disapprove the SMP, EPA makes its final determination that unreasonable 
adverse effects may be present without additional State measures, 
relying on the record developed by the State during the SMP process, as 
well as on the record of this initial rulemaking establishing the SMP 
restriction.
    3. Indian lands. It is EPA's intent in proposing this rule that no 
geographic area be excluded from coverage by an EPA-approved SMP upon 
the effective date of the regulation. To this end, Indian Tribal 
authorities will have the opportunity to develop Tribal SMPs in the 
event they wish to allow sale and use of these five pesticides on 
Indian lands under their jurisdiction. A few Indian lands have already 
received Federal financial assistance through FIFRA program grants to 
develop Generic SMPs. Indian tribes preparing SMPs would be subject to 
the same procedures and requirements that are described here for 
States.
    However, Indian tribal authorities will not be required to develop 
Plans if they have no interest in allowing sale and use of the five 
pesticides within their jurisdiction. Furthermore, Indian tribal 
authorities that are interested in preserving sale and use of any of 
these five pesticides within their jurisdictions, but believe they are 
not able to commit the resources required to develop or implement a 
Plan, might be able to reach an agreement with an adjoining State 
authority to extend coverage of the State Plan to the Tribal lands. 
Such an agreement would have to be submitted to the pertinent EPA 
Regional Office for review.

C. Plan Requirements

    An EPA-approved SMP will consist of 12 specific components, each 
developed in sufficient detail and scope to demonstrate the adequacy of 
the Plan. ``Adequacy,'' as generally used here and in the regulatory 
text, means that the content of, or commitment contained in, each 
component demonstrates that the general objective in establishing an 
SMP is met: preventing ground-water contamination by the pesticide or 
pesticides subject to this proposed rule, that may present adverse 
effects to human health and the environment. This entails an evaluation 
of the

[[Page 33268]]

adequacy of the State's proposal. A State's submission will not be 
satisfactory if it only provides a ``description'' of a provision, 
without regard to whether the provision represents adequate groundwater 
protection. Provisions cannot be merely ``adequately'' described; they 
must provide for successful implementation of ground-water protection. 
A Regional Administrator could disapprove a Plan on the basis of 
finding one or more of the components submitted will not fulfill the 
general objective for which EPA decided to make the pesticide subject 
to SMPs in the first place: the provision of State management measures 
that will prevent unreasonable adverse effects and protect the 
environmental integrity of the State's ground water.
    Each State Plan, for each pesticide proposed for SMPs, must address 
each of the 12 components. These components are being proposed under 
the new 40 CFR 152.190. The proposed requirement that an acceptable SMP 
contain 12 components still gives a State a large degree of flexibility 
in managing the use of the pesticides subject to SMPs. While all 12 of 
these components will need to be discussed in an SMP, States will be 
allowed a substantial range of flexibility in the form and manner by 
which they propose to perform the functions contained in each 
component. This variability will reflect differences in State ground-
water protection philosophies and regulatory approaches. Further, the 
Agency anticipates that the contents of State Plans will vary in 
extensiveness and detail according to the potential magnitude of the 
ground-water contamination threat. The Agency expects that in low-risk 
circumstances (e.g., a State in which a subject pesticide is not 
currently used, or in which use is limited to areas with a minimal risk 
of contamination), an acceptable SMP may need to be little more than an 
augmentation to a ``Generic'' SMP, showing how the State would move to 
a greater level of effort in the event the original low-risk 
circumstances change, or new evidence warrants. The Agency does not 
intend that a State will necessarily impose regulatory restrictions on 
every area of use or specific crop use pattern within a State involving 
a subject pesticide; if there is an appropriate basis for determining 
that an area or use site does not pose a significant risk of ground 
water contamination, the State's SMP might not require any change in 
user practices from the current Federal label. However, a State 
proposing such a position in its SMP would have to provide a reasoned 
basis for its conclusion that the risk of ground-water contamination 
for a particular geographic area or use site is such that further 
restriction is not required. EPA is prepared to accept this manner of 
variation among State plans; indeed, the need for this flexibility is 
the foundation of the entire SMP approach.
    As a general matter, EPA Regional Administrators will evaluate each 
component individually and as each complements the other components. In 
many cases, the adequacy of a particular component's contents will 
depend in a material way on the contents of another component. Again, 
this approach is expected to give States a great deal of flexibility. A 
good example of this is the interrelationship between the 
``monitoring,'' ``assessment,'' ``prevention'' and ``response'' 
components. States may differ in judging the relative efficacy of 
assessment methods for estimating the sensitivity of aquifers to 
contamination, versus ground-water monitoring. As a result, one State 
could put little emphasis on the assessment efforts, but compensate by 
placing a more substantial emphasis on monitoring. Another State could 
choose the opposite. Either approach could very well prove to be 
adequate. Still another State might view relying on either or both as 
deficient, and choose to emphasize prevention by imposing more 
stringent use-management measures more routinely. However, a State Plan 
that committed to a minimal effort in all three spheres could well be 
found to be inadequate. These interrelationships are discussed in more 
detail under the specific component headings in the Guidance. Thus, 
each Regional Administrator will be evaluating each component on its 
own merits, but also how all of the individual components work together 
to fulfill the ultimate objective of protecting ground water.
    Furthermore, the Agency recognizes that certain elements of SMPs, 
particularly the vulnerability assessment and monitoring components 
(described below), entail extensive technical activities and 
substantial long-term resource commitments. One purpose in promoting 
the development of ``Generic'' SMPs is to provide for a head start in 
developing such technical capacity. However, the Agency does not expect 
that an acceptable SMP must in every instance have such components 
fully developed and in place at the time the State Plan is approved. 
Rather, an acceptable SMP may be at times one that provides an 
adequate, credible commitment and action plan to phase in such 
components in order to meet the State's ground-water protection goal 
specified in their SMP. Failure by the State to meet the commitments 
made in the SMP would result in EPA reconsidering the original decision 
to approve the SMP.
    The Guidance, in chapter 3, describes EPA's expectations as to what 
an adequate State submission will entail. As a general rule, EPA will 
apply the criteria set forth in the Guidance in determining the 
adequacy of individual State plans. Obviously, guidance criteria are 
not intended to be as rigid as requirements established in regulations. 
However, a Plan is more likely to be acceptable if it conforms as much 
as possible to the provisions of chapter 3 of the Guidance. A State 
submission that fails to meet these criteria risks disapproval.
    The Agency notes that, since State Management Plans are a new and 
evolving regulatory mechanism, the guidance for implementing Plans will 
also evolve. Thus, the Agency is likely to issue further clarifications 
to the Guidance as issues are raised by Regional Offices and States. 
For example, the comments that EPA receives in response to this 
proposed rule may be an important source for identifying such issues.
    The following sections briefly describe each of the 12 mandatory 
components of an adequate State Management Plan being proposed in 
Sec. 152.190.
    1. State's philosophy and goals toward protecting ground water. 
Proposed Sec. 152.190(a) would require that a Plan describe the State's 
philosophy and goals for protecting ground water. An acceptable plan 
must demonstrate that the State's goals and objectives are no less 
protective than EPA's goal of preventing unreasonable adverse effects 
to human health and the environment and to protect the environmental 
integrity of the nation's ground-water resources.
    EPA's strategic approach emphasizes the prevention of contamination 
over remedial treatment. Further, it focuses priorities on sources of 
drinking water currently used, or reasonably expected to be, and ground 
water that is closely hydrologically connected to surface waters. While 
a State's goal must be no less protective than the Agency's, States 
will be free under the regulation as proposed to articulate its ground-
water protection philosophy and goals in alternative form and language. 
In any case, a State submission, to be judged adequate, must include a 
statement that addresses both the ground waters to be

[[Page 33269]]

protected and the degree of protection to be achieved under the SMP.
    2. Roles and responsibilities of State Agencies. State efforts to 
implement the Strategy will, out of necessity, require extensive 
coordination among State health, environment, agriculture, and water 
agencies. The SMP must include a description of the roles and 
responsibilities and coordination mechanisms of involved State 
agencies. For an SMP to be found adequate by EPA, it must satisfy six 
general provisions set forth in proposed Sec. 152.190(b). For a further 
description of what these provisions entail, refer to pages 3-4 and 3-5 
of the Guidance.
    3. Legal authority. A State's ability to carry out prevention and 
response actions for pesticides in ground water is dependent on its 
legal authority to regulate pesticide use and protect ground water, to 
be provided pursuant to the provisions of proposed Sec. 152.190(c). 
Regulatory authorities must be sufficient to accomplish the desired 
outcomes of the SMP. EPA will consider this component in parallel with 
the provisions of proposed Sec. 152.190(i) on enforcement mechanisms. 
Descriptions of enforcement authorities provided in this component 
should be cross-referenced to that component as well. One suggestion is 
that the State provide a graphic ``crosswalk'' of legal, regulatory and 
enforcement authorities (e.g., a side-by-side comparison of SMP 
requirements as described in proposed Sec. 152.190, and corresponding 
State authorities for implementing each requirement, modelled after 
what is currently provided for in the Public Water System program [40 
CFR part 142.12(c)].
    Under Sec. 152.190(c), a State's plan must identify the specific 
legal authorities to be used in implementing the plan, to ensure that 
the State's submission is legally enforceable. Presently there is no 
provision that the State's chief legal officer be required to examine 
the submission, and be satisfied that the appropriate provisions of the 
plan are legally enforceable under State law. Several other EPA 
programs require a certification from the State Attorney General (or a 
designee) to ensure that there is sufficient legal authority to enforce 
provisions of the program. This approach provides further assurance 
that all of a State's rulemaking procedures have been followed, and 
that, as a result, the SMP is enforceable under State law. Such a step 
should reduce the likelihood that a legal challenge to the rule will 
not be sustained, and should entail a small resource requirement on the 
State. EPA is soliciting comment on whether the Agency should also 
require in the final rule that the State's submittal include such a 
certification.
    4. Resources. A State's ability to carry out the commitments 
delineated in its SMP depends on the resources available to implement 
the program. Resources include technical expertise and personnel, 
physical and operational capabilities, and funding. Proposed 
Sec. 152.190(d) requires that the SMP demonstrate that the necessary 
expertise is available and that there is an adequate match between 
revenues and proposed expenditures. This demonstration must:
    i. Indicate what categories of personnel or technical expertise are 
necessary and available for implementation of the Plan.
    ii. Include an estimate of the costs, both physical and 
operational, to develop and implement each element of the Plan.
    iii. Disclose the current funding available for implementation of 
the program, existing and potential funding sources for the future, and 
a commitment to pursue additional funding if needed.
    EPA will only be evaluating the adequacy of the resources specified 
in determining the adequacy of the overall Plan, and will not be 
judging the manner in which the State provides for those resources. 
However, EPA strongly encourages States to develop innovative means to 
finance and implement SMPs, such as user and/or sales fees, in order to 
reduce the burden on a State's general revenues. EPA will also explore 
ways of helping to shift some of the financial burden of implementing 
SMPs from the States to registrants, for example, in providing for 
concurrent National ground-water monitoring requirements.
    5. Basis for assessment and planning. One of the fundamental 
principles in the Strategy is the tailoring of protection activities to 
the unique hydrogeologic settings, pesticide usage patterns, and 
agronomic practices of each State. The effectiveness of protection 
activities depends to a large extent on the degree to which vulnerable 
areas in need of protection can be accurately identified. Therefore, 
States must have an ongoing program that provides basic information on 
the occurrence, movement, and quality of ground water in relation to 
patterns of pesticide use. State Agencies of environment, water, 
agriculture, and health must all have the opportunity for input into 
this program. Pages 3-7 and 3-8 of the Guidance (supplemented by 
chapter 3 of the Guidance's Appendix B) describe in further detail the 
function and activities embodied by the term, ``assessment and 
planning.''
    The component prescribed by the proposed Sec. 152.190(e) is, for 
practical purposes, a description of the process by which a State will 
set priorities for prevention and response actions. In this component, 
the State will describe how it will assess ground-water vulnerability, 
use and value and how that assessment will be used: (a) To set 
priorities for protection activities; (b) to design and implement 
prevention and response measures; and (c) to determine the 
effectiveness of these measures and of the implementation of the 
overall Plan. An adequate SMP for these five pesticides must include a 
description of how the State will address vulnerability assessment on a 
sub-county level for the geographic area in which the State intends to 
allow continued use of the pesticides. EPA considers this level of 
geographic detail necessary in ground-water vulnerability assessment 
because it is generally held that current methods of vulnerability 
assessment are generally not capable of 
FR Doc. 96-16173 Pesticides and Ground Water State Management Plan Regulation
predicting the vulnerability of 
broader geographic areas, such as counties. It is widely held that the 
hydrogeologic factors which influence the sensitivity of particular 
ground waters vary within areas smaller than typical American counties. 
Distinguishing areas of different ground-water sensitivity must involve 
``sub-county'' geographic units (see the Guidance and its Appendix B 
for further discussion of the basis for these opinions). It is also 
generally accepted that such assessments will entail a substantial 
level of effort. There is no standard definition of what the size or 
dimensions of a ``sub-county'' unit might be, other than the general 
observation that it is an area that is relatively homogenous with 
respect to the hydrogeologic characteristics that influence ground-
water sensitivity.
    While an adequate SMP must discuss what the State's approach to 
vulnerability assessment at the sub-county level will be, it must also 
discuss the limitations of its assessment techniques and how these 
limitations are taken into account in the design of prevention and 
response programs (see g. and h., below). For example, a State could 
describe in its submission for this component that it does not or 
cannot currently perform adequate vulnerability assessments to the 
desired level of detail, but then explain how the State will impose 
more restrictive pesticide use practices across a wider geographic area 
(e.g., an entire county where a pesticide might be used) so as to 
protect the most vulnerable ground waters within that area. In other 
words, if a State applies prevention measures

[[Page 33270]]

on broad regional or county-level designations, then sub-county level 
assessments may not be needed. However, the State should explain why 
the measures chosen are likely to be adequate to meet program goals. 
Conversely, if a State plan allows sub-county or farm-level 
distinctions in applying prevention measures, it should explain the 
basis for making such distinctions, and how protection goals will be 
met. EPA's expectations as to the adequacy of this component are 
further discussed in pages 3-8 through 3-10 of the Guidance.
    6. Monitoring. Broadly defined, ``ground-water monitoring'' is the 
set of activities that provides chemical, physical, geological, 
biological, and other environmental data needed by environmental 
managers/decision-makers to assist in developing and implementing 
ground-water protection policies and programs. Ground-water monitoring 
is viewed as a continuum of activities ranging from defining background 
conditions, to defining the existence and extent of contamination, to 
defining the success of prevention and response measures and programs 
to protect the ground-water resource. The Guidance (in pages 3-10 to 3-
11 and in Chapter 5 of Appendix B) discusses in further detail the 
dimensions of ground-water monitoring activities and their various 
functions in programs aimed at preventing pesticidal contamination of 
ground water.
    An adequate SMP must describe the State's monitoring program for 
pesticides, the uses to which monitoring will be applied, and the 
parties responsible for various functions associated with monitoring. A 
current, approved State Quality Assurance Project Plan (QAPP), as 
described in chapter 5.4.2 of the Guidance's Appendix B, is a 
prerequisite for approval of an SMP. The provisions of such a plan will 
apply to data collected by the State as well as to any data collected 
by some other party on behalf of the State, for the purposes of 
performing the State's monitoring component. Such a quality assurance 
plan will provide sufficient assurance of the integrity of the data so 
as to preclude the applicability of the Agency's Good Laboratory 
Practices (GLP) regulations (40 CFR part 160). However, certain 
conceivable data collection activities (e.g., monitoring studies 
required by EPA as an adjunct to State monitoring, described in the 
next paragraph) could be subject to GLP Standards. The distinction 
would lie in: (1) Whether the monitoring activity is described in, 
referred to, or otherwise pursuant to, the monitoring component of the 
approved SMP; and (2) whether the monitoring activity directly relates 
to the maintenance of the Federal registration of the pesticide. For 
example, monitoring activities performed by a third party (e.g., a 
university) under the authority of the State's monitoring plan would be 
subject to QAPP provisions. Registrant monitoring directed by the State 
would similarly be subject to the State's QAPP. However, registrant 
monitoring performed either at EPA's behest or performed on the 
registrant's own initiative (but without State mandate or not at the 
State's behest) would be subject to EPA's GLP standards.
    The essential criteria to determine the adequacy of the monitoring 
component of a State Plan are whether the State's monitoring effort is 
appropriate to achieve the purposes of the Plan, and whether the level, 
quality and extent of specific monitoring efforts provide a reasonable 
likelihood that contamination representing an unreasonable risk to the 
environment will not go undetected. As discussed earlier, the judgement 
of the adequacy of a monitoring component must be made in consideration 
of the stated goal of the Plan, and the contents and design of its 
constituent assessment and protection components. Further discussion of 
EPA's expectation of what constitutes an adequate monitoring component 
can be found in the Guidance (pages 3-11 through 3-13).
    EPA assumes that monitoring activities will represent a significant 
portion of a State's resource investment in implementing its SMPs. 
Based on past State experience, EPA estimates in its Regulatory Impact 
Analysis for this proposed rule (see Unit V. of this preamble) that 
ground-water monitoring activities by themselves may constitute between 
10 to 14 percent of the annualized State program costs. Furthermore, 
the costs of performing ground-water monitoring can be expected to vary 
widely across the country, inasmuch as the States are starting from 
different points in the degree of current monitoring. To help alleviate 
this resource requirement on the States, EPA is considering development 
of national-level requirements (pursuant to its data-call-in 
authorities under FIFRA section 3(c)(2)(B)) for additional ground-water 
monitoring from the registrants of these five pesticides. Such 
concurrent data-gathering requirements would be developed with 
reference to submitted State Plans, so that the ultimate requirement on 
the registrants would not be unduly burdensome and would be tailored to 
the strengths and weaknesses of actual SMPs. Such a requirement would 
also be designed to provide States the opportunity to review and 
comment on Federal specifications to the registrants, to ensure harmony 
with State intentions.
    7. Prevention actions. The emphasis of EPA's Pesticides and Ground-
Water Strategy is on prevention, and the core of an acceptable SMP will 
be its program of managing particular pesticide use in order to prevent 
contamination. Preventive management approaches may vary based on 
ground-water vulnerability and ground-water use and value, as well as 
social and economic factors. The actual measures employed may range 
from education of users, voluntary or mandatory best management 
practices, such as changes in application rates, methods and timing, 
all the way to use prohibitions in specific areas. As noted above, the 
Agency does not necessarily expect that SMPs will impose new 
restrictions on every use site or geographic area in which a pesticide 
is used in a State; if there is a reasonable basis for determining that 
risks for particular use sites or areas are not unreasonable, then 
little or no change from current label requirements may be needed.
    Prevention measures may overlap with response measures at the point 
that pesticide contamination of ground water is detected. For example, 
when pesticides are detected, preventive actions can still be pursued 
to prevent further contamination. States may choose to combine their 
prevention and response discussions because of this overlap.
    Appendix B: Assessment, Prevention, Monitoring, and Response 
Components of Pesticides State Management Plans of the Guidance 
identifies ground-water protection practices and methods for 
implementing prevention efforts that States may consider in the 
development of their prevention component. The methods described there 
are not considered an exclusive list of available options. The Agency 
fully expects some States to develop innovative measures to achieve 
their ground-water protection goals.
    Because of the wide variety of possible approaches a State might 
adopt to fit a wide variety of local circumstances, proposed 
Sec. 152.190(g) is worded very generally in order not to restrict the 
States' flexibility. While EPA is proposing that the rule provide for 
maximum flexibility in State program design, it acknowledges that other 
approaches are feasible. In recognition of this fact, EPA elsewhere in 
this preamble (see section D of this Unit) is requesting public comment 
on

[[Page 33271]]

alternative approaches to prevention program requirements.
    The relation of these prevention programs to other risk-management 
measures will be an important consideration for the States in the 
development of SMPs. These SMPs are required to address the ground-
water contamination potential of the five pesticides subject to today's 
rule. It happens, however, that these pesticides also represent a well-
documented risk of surface water contamination, at least in some of 
their use-areas (see, for example, ``Triazines Water Resources Impact 
Analysis'' (Ref. 19)). Thus, an acceptable Plan for these pesticides 
must include consideration of whether specific measures employed by a 
State to protect ground water might elevate risks to surface water. For 
example, a Plan which would change a tillage practice to reduce 
pesticide infiltration of ground water may in some instances increase 
runoff to surface water. EPA therefore strongly encourages States to 
implement measures to protect surface water from pesticide 
contamination that is likely to impair water quality. Specifically, 
States should coordinate the development of preventive measures with 
measures under existing EPA programs, such as the Nonpoint Source, 
Coastal Zone Management, Wellhead Protection, and Comprehensive State 
Ground Water Protection Programs. Measures must also be coordinated 
with the USDA Soil Conservation Service's Compliance Conservation 
Plans.
    As discussed in Unit IV.B. of this preamble, adverse ecological 
effects associated with these compounds are a concern, and a reason for 
proposing the compounds for SMPs. Because the ability to identify 
ground-water discharge to surface water is limited by resources and the 
current state of scientific knowledge, EPA will not disapprove out of 
hand any proposed State Plan that fails to specifically address ground 
water supporting surface water ecosystems in either the ``basis for 
assessment and planning,'' ``monitoring,'' ``prevention,'' or 
``response'' components. However, States that are aware of specific 
bodies of water that receive a large percentage of their recharge from 
ground water are strongly encouraged to attempt to take this fact into 
account in designing the above components of their Plans. As in 
evaluating the adequacy of any and all the elements of State proposals, 
reviewing EPA regional offices will evaluate the adequacy of State 
measures to address such ``closely hydrologically connected'' ground 
waters on the basis of its own and the State's assessment of the 
State's vulnerability in this respect.
    Similarly, if a State expects that a risk reduction measure will 
lead users to use alternative chemicals, then EPA encourages the State 
to consider whether the alternative chemicals will cause adverse 
effects to ground water, surface water, other areas of the environment, 
or other types of risk, such as risks to pesticide applicators. In 
other words, the State, in its Plan, should provide a reasonable 
assurance that the preventive measures it proposes to protect ground 
water are not likely to result in unreasonable adverse effects 
elsewhere in the environment as a consequence.
    8. Response to detections of pesticides. This component will 
describe how the State plans to respond to contamination to ensure that 
reference points (MCLs, HAs, or State quality standards) will not be 
reached in ground water, and what actions the State will take in the 
event that the reference points are reached or exceeded. Response 
measures should be based on the State's ground-water philosophy and the 
assessment and monitoring components. Further, this component is 
closely tied to the requirements concerning prevention, which specify 
that an SMP must describe actions that the State will take initially in 
the absence of actual detection and those it will implement if the plan 
appears to be failing to protect ground water. SMPs should describe how 
the appropriate State agencies will be brought into remedial actions.
    Response actions, such as increasing implementation of best 
management practices, and use restrictions or prohibitions, are the 
focus of this component, rather than remediation activities. Since 
FIFRA provides limited means for responding to contamination, however, 
States should increase efforts to coordinate enforcement and other 
response activities under a number of other Federal/State authorities. 
In addition, as in proposed Sec. 152.190(g), States should coordinate 
response measures with measures under existing EPA programs, such as 
Nonpoint Source, Coastal Zone Management, Wellhead Protection, and 
Comprehensive State Ground Water Protection Programs. Appendix B of the 
Guidance presents a framework for assessing and responding to ground-
water contamination by pesticides as well as suggested response 
alternatives. Again, EPA does not regard the Guidance as providing an 
exclusive list of options, since new information becomes available on a 
routine basis. For example, EPA is developing new guidance accompanying 
its new Hazardous Waste Identification Rule, defining ``best management 
practices'' (BMPs) for the treatment of contaminated media at 
remediation sites, in order to reduce the potential for cross-media 
contamination. Such ``BMP Guidance'' will help States reduce the 
possibility of incidental contamination of ground water at remediation 
sites. A review draft guidance document has been available since April 
1996.
    9. Enforcement mechanisms. To meet this requirement, the Plan must 
describe the State's enforcement capabilities, authorities, and 
compliance activities (e.g., inspections, technical support, penalty 
provision, etc.), if not already described pursuant to proposed 
Sec. 152.190(c). The SMP also needs to identify the State agency with 
each enforcement authority and how coordination of enforcement 
capabilities will work to prevent and respond to contamination.
    In addition, a Pesticide Plan must discuss the State's enforcement 
authorities and capabilities to monitor compliance with the specific 
measures included in the SMP, both those intended to protect ground 
water from contamination and response actions where contamination has 
already occurred. Further discussion of enforcement requirements can be 
found on pages 3-18 to 3-19 of the Guidance.
    10. Public awareness and participation. Most government activities 
are subject to citizen involvement and review. An acceptable Plan must 
demonstrate that the public has opportunity to be involved in the 
process of Plan development and will be informed of significant Plan 
implementation activities. The Plan must address three different 
aspects of necessary public awareness and participation. The Plan must:
    i. Describe the opportunities for public input regarding 
development of the Plan and decision-making in implementing it.
    ii. Indicate how, when, and by whom the public will be informed of 
detections in ground water that are considered significant.
    iii. Include a description of the process and means of 
communication by which the public will be made aware of important 
regulatory actions taken under the SMP. More discussion of public 
participation issues can be found on pages 3-19 to 3-20 of the 
Guidance. However, as discussed earlier in this unit, EPA expects that 
in fulfilling the first requirement, a State will at a minimum provide 
notice and opportunity to comment on whether the SMP under development 
satisfies the criteria for SMPs proposed in this rule,

[[Page 33272]]

including an opportunity to assess costs and benefits under the 
proposed SMP.
    11. Information dissemination. The user is responsible for directly 
controlling the use of pesticides in the field. Therefore, an important 
part of any SMP must be the means by which ground-water protection 
measures and other Plan requirements are communicated to pesticide 
users as well as to appropriate industry groups and regulatory 
officials (proposed Sec. 152.190(k)). Further discussion of this 
requirement is provided in the Guidance (pages 3-20 to 3-21).
    12. Records and reporting. Documentation of a State's program not 
only serves as a source of data to share with EPA and other involved 
Federal and State agencies, but also provides a basis on which to 
assess the effectiveness of a State's prevention and response measures. 
An adequate SMP discussion of records and reporting will identify both 
management measures relating to the State's progress in implementing 
the Plan and environmental indicators of the effectiveness of the 
program. The Guidance provides a fuller description of the reporting 
requirements established by the new Subsection (l), particularly the 
key ``Biennial Report'' (pages 3-21 to 3-24). In addition, Chapter 5 of 
the Guidance's Appendix A provides a fuller discussion of the Biennial 
Report requirements pursuant to the provisions of this proposed rule 
for evaluation of EPA-approved Plans.

D. Evaluation of State Management Plan Implementation

    Once in place, SMPs are a permanent condition of registration for 
the pesticide, for as long as the pesticide remains registered. 
Proposed Sec. 152.191 of the new subpart J provides for EPA evaluation 
of State implementation of their Plans. Periodic evaluations of the 
implementation of SMPs will measure the State's progress towards its 
goals and commitments, determine the environmental effectiveness and 
the level of ground-water protection provided by the Plan, and ensure a 
minimum level of national consistency.
    EPA will use the SMP Biennial Report required in proposed 
Sec. 152.190(l)(2) to evaluate a State's effectiveness in protecting 
its ground-water resources from pesticide contamination. Both the 
general provisions for EPA's evaluation of approved SMPs and the 
Agency's expectations about the form and content of the Biennial 
Reports are described in greater detail in Chapter 5 of Appendix A of 
the Guidance. In specifying an evaluation requirement, EPA recognizes 
that States have a variety of evaluation methodologies and measures at 
their disposal.

E. Amendment of State Management Plans

    Once in place, State Management Plans will have considerable built-
in flexibility, in order to respond to a variety of circumstances. For 
instance, the response component entails a range of options for 
responding to contingencies triggered by pesticide detections in ground 
water; new information about pesticide usage patterns; and new 
information on ground-water vulnerability, use and value. Consequently, 
Plans will probably not need frequent revision and update. If the range 
of options in a given Plan turns out not to meet the State's needs, 
however, States may need to modify and update plans. States should 
consider revising SMPs:
     If EPA's periodic evaluation of the SMP determines that 
the provisions in a State's SMP are not adequately protecting the 
ground-water resource from pesticide contamination.
     If the statutory or regulatory framework for SMP 
development and implementation changes.
     If more comprehensive ground-water vulnerability 
assessments, additional monitoring methods, improved prevention 
technologies or new information concerning the risks posed by a 
pesticide become available and need to be accommodated in order to make 
the Plan more effective.
     If a State, through experience, finds substantially 
different, more effective ways to assess ground-water contamination, 
prevent or respond to contamination, or disseminate information.
     If changes in crops or crop production systems within the 
State are significant enough to require different pesticide management 
measures in order to manage risks to ground water.
     If roles and responsibilities of State agencies materially 
change.
    Section 152.193 provides for the modification and update of SMPs 
under these circumstances.
    Ordinarily, a State will submit needed amendments as part of the 
SMP Biennial Report. In an urgent case, a State may appeal for revision 
outside the biennial review process to the Regional Administrator. In 
addition, if the Regional Lead Office determines through the evaluation 
process that the SMP needs to be amended, then the Regional 
Administrator can initiate the amendment process by requesting that the 
State submit an SMP Update Report. Chapter 6 of the Guidance's Appendix 
A describes the process EPA envisions for the modification and update 
of approved SMPs.

F. Withdrawal of Approval of a State Management Plan

    Section 152.195 of the proposed regulatory text provides for EPA 
withdrawal of its approval of existing State Plans under certain 
circumstances. Withdrawal of approval can begin when:
     The State fails to demonstrate that it is satisfactorily 
implementing the SMP as approved.
     The State's SMP is not protecting ground water from 
contamination above the ground-water reference point.
     The State fails to address deficiencies identified in the 
SMP Evaluation (per proposed Sec. 152.191), by updating the SMP (per 
proposed Sec. 152.193) and/or improving implementation of the SMP.
    EPA envisions such revocation of a State's Plan to be generally a 
last resort. Before the withdrawal process commences, the State will 
have the opportunity to respond to EPA-identified deficiencies in its 
Pesticide SMPs through the SMP amendment process or by demonstrating to 
the Agency that the SMP is being satisfactorily implemented. Regions 
will work closely with individual State agencies or the State Liaison 
to assist the State in updating the plan or in addressing deficiencies 
or gaps in protection.
    Withdrawal of approval of an SMP (as discussed in greater detail in 
the Guidance's Appendix A, Chapter 7) is a multi-step process. EPA 
would commence the withdrawal process by issuing a formal letter from 
the Regional Administrator (acting for the Administrator) to State 
officials responsible for implementing the Plan. The notice will 
include:
     A statement concerning the potential withdrawal of the 
SMP.
     A listing of the deficiencies of the SMP or a description 
of the failure of the Pesticide SMP to protect ground water.
     A brief summary of the events that led to the withdrawal 
notice, e.g., failure to respond to SMP's deficiencies in the Biennial 
Report and failure to update the SMP adequately.
     A time frame in which the State can respond to the 
deficiencies to stop the withdrawal process e.g., time frames for 
submitting an SMP Update Report, for improving implementation of the 
plan.
    In the event this letter fails to elicit a satisfactory State 
response, EPA's next step is a second notice, announcing imminent 
publication of a Federal Register notice withdrawing EPA's

[[Page 33273]]

approval of the SMP. In the event this second letter does not elicit a 
satisfactory resolution, the final step is publication of a Notice of 
Withdrawal in the Federal Register. This withdrawal of EPA's approval 
will have the effect of prohibiting the sale and use of the pesticide 
in the State. Chapter 7 of the Guidance's Appendix A has a further 
description of the Agency and State roles and responsibilities in this 
process.
    Proposed Sec. 152.195 provides the State the opportunity to respond 
to EPA's initial decision to withdraw approval in at least two 
different ways. The State may respond in writing to the notice with a 
commitment to address the deficiencies in the SMP itself or in SMP 
implementation. In this case, the State must respond to the initial 
notice within 30 days of receiving it. However, the State may choose to 
appeal the EPA decision to initiate withdrawal. In that event, the 
State may request a meeting with the Regional Administrator (who will 
be the deciding official in these instances); that request must be made 
within 60 calendar days of the date of the initial notice. If the State 
does not respond to the initial notice within either of these time 
frames, or consultations pursuant to the initial notice fail to resolve 
EPA's concerns, the Region will take the next step of sending a second 
letter, and ultimately, of publishing a Federal Register notice.
    In some instances EPA may find an SMP (or its implementation) is so 
deficient that further sale and use under its provisions would 
constitute an unreasonable risk to the environment. If so, the Regional 
Administrator may also prohibit sale and use of the pesticide during 
the withdrawal process if, in his or her judgement, continued use of 
the pesticide in the State under the conditions of the deficient SMP 
presents an unreasonable risk to human health or the environment. In 
this event, EPA would propose a temporary prohibition in a Federal 
Register notice, in addition to the letters to the States described 
above. This notice would explain the Regional Administrator's judgement 
that unreasonable risks to the environment may be present during the 
time required for correcting the deficiencies in the State's Plan, and 
solicit public comment on the impending prohibition. This Federal 
Register notice could be published simultaneously with the initial 
letter to the State, or at any time after that initial letter, in the 
event the Regional Administrator found an unreasonable risk to the 
environment was impending. After addressing any public comment, the 
Regional Administrator would implement the temporary prohibition. The 
prohibition of sale and use would remain in effect until the State and 
EPA reach agreement on how to address the SMP's deficiencies.

G. Label Changes

    This regulation requires a change to the label of any pesticide 
subject to an SMP, so that users will be aware of their responsibility 
to use a product in accordance with the provisions and restrictions of 
an EPA-approved SMP. All products subject to an SMP must bear the 
following statement describing the SMP restriction itself:

    For use only in accordance with an EPA-approved State Management 
Plan (SMP) for ground-water protection. Sale and use are prohibited 
in States that do not have an EPA-approved State Management Plan.

Each State Plan will provide for other means, separate from the product 
label, to disseminate to pesticide users specific additional 
provisions, management measures and geographic restrictions. These 
State-specific information dissemination measures are intrinsic to the 
SMP in accordance with Sec. 152.190(k) described above. However, 
additional information may be placed elsewhere on the label in order to 
direct users to appropriate State sources for more information, or to 
describe in more detail SMP requirements. Such information will not 
appear in the Restricted Use area of the front label, but preferably 
within the Directions for Use portion of the label.
    In Sec. 152.185(b) of the new subpart J, EPA proposes that 
registrants adhere to the same provisions for label changes, 
distribution and sale and advertising as apply to pesticides classified 
for conventional restricted use. In addition, registrants of pesticides 
classified for SMPs need to submit proposed labels specifying the SMP 
classification within 3 months of the effective date of the SMP 
provision.
    An amended label containing the narrative restriction specified in 
this proposed rule must be submitted by each registrant of a product 
classified by this proposed rule to be subject to SMPs within 12 months 
of the publication of the final rule; and the amended label must be 
affixed to all products subject to this classification on the effective 
date for the rule.
    EPA is proposing in this document to reorganize part 156, the 
regulation specifying labeling requirements for pesticides and devices. 
Part 156 is now organized so that paragraphs (a) through (j) of 
Sec. 156.10 each describe one of nine specific components of a 
pesticide product label. EPA proposes that the last two paragraphs of 
Sec. 156.10 become a separate subpart. EPA regards these as 
particularly important components. Specifically, the Agency is 
proposing to amend part 156: (1) By creating a new subpart G to 
encompass the existing paragraphs (i) and (j) of Sec.  156.10; (2) 
redesignating paragraph (i) as two new sections, Sec. Sec.  156.120 and 
156.121, within this new subpart G; and (3) creating new Sec. Sec.  
156.135, 156.136 and 156.137 within this subpart G (from the previous 
paragraph (j)) to describe labeling pertaining to use classification, 
including both conventional restricted use to certified applicators and 
restriction to use under approved SMPs. The new label statement to 
accompany a product classified for SMPs is specified in the new 
proposed Sec. 156.137(c)(2). As proposed, the SMP statement would 
appear under the ``Classification'' heading, because legally, an SMP is 
a form of classification pursuant to the ``other regulatory 
restrictions'' authority in FIFRA section 3(d).

H. Request for Comments

    EPA is interested in receiving comments on all aspects of its 
proposed 40 CFR part 152 subpart J. For instance, is the effective date 
of 33 months after promulgation of the rule appropriate? Does it permit 
sufficient time for registrants to make the necessary label changes? 
Does it permit States sufficient time to develop Plans and EPA to 
review them before the restriction is effective? Does the proposed 
development, review and approval process provide sufficient public 
opportunity to comment on the contents of the Plan before its approval 
and implementation as a regulatory restriction? Has EPA properly 
specified the criteria which State Plans must meet? Has EPA provided 
sufficient mechanisms for appealing decisions to approve or disapprove 
Plans, and for evaluating, amending, and revoking Plans? Is two years a 
sufficient interval for EPA to require States to report on their 
implementation of SMPs? What further measures could be employed to 
encourage States to prepare Plans for pesticides with minor uses within 
their boundaries, so as to provide for their appropriate continued use? 
Should EPA concurrently develop National datagathering requirements to 
be applied to the registrants of the pesticides subject to SMPs, with 
the intent of easing States' ground-water monitoring burdens? If so, 
how should the Agency design such a requirement, i.e., balancing 
between helping the States with their monitoring efforts and not 
infringing on States' flexibility and

[[Page 33274]]

power to prescribe its own monitoring regimen? What further national-
level resources (e.g., technical assistance from the USDA's Natural 
Resources Conservation Service) should be anticipated for supporting 
development of State Plans? Should EPA classify a pesticide for 
``conventional'' restricted use classification at the same time it 
determines the pesticide must be subject to SMPs, in this or a 
subsequent rule? Should EPA propose a new form of labeling for 
pesticides classified for SMPs, to distinguish those pesticides from 
pesticides classified as ``conventional'' restricted use?
    In addition to comments on issues like those described above, the 
Agency is interested in receiving comments on alternative approaches to 
the specification of State prevention-program components. Within the 
general framework of the SMP approach, there are many ways to specify 
how States will perform the duties of protecting ground water from 
contamination by pesticides. The approach being proposed today is in 
conformance with the previously published Guidance, which remains the 
Agency's preferred approach. EPA believes the approach developed in the 
Guidance provides for maximum flexibility in developing the means of 
ground-water protection, within the broad determination by the Agency 
that these pesticides warrant additional regulatory restriction. This 
flexibility, in turn, maximizes the opportunities for State initiative 
and effectiveness in tailoring its ground-water protection efforts.
    At the same time, the balance between national consistency and 
State flexibility may be struck in numerous other ways, while still 
maintaining a fundamental partnership between EPA and the States. The 
Agency is pecifically soliciting comment on how to strike this balance, 
within the general consensus it believes exists on the existence of 
Federal and State roles. For instance, should EPA require an SMP to 
include regulatory action to prohibit use of the pesticide under SMPs 
in areas where contamination from current, legal use exceeds the 
reference point in current or reasonably expected sources of drinking 
water? If so, should EPA also require States to complete their 
identification of current and reasonably expected sources of drinking 
water (if States choose to make such a delineation) prior to Plan 
approval?
    In addition, EPA is soliciting comment on whether it would be 
helpful for the Agency to provide more specific guidance to States (in 
the form of technical assistance, new guidance documents or amendments 
to the existing Guidance) on particular risk-reduction measures that 
may be appropriate to particular indications of present groundwater 
contamination. Such guidance would not be prescriptive (that is, 
codified in rulemaking), but rather reflect the best experience of EPA 
and the States in managing ground-water protection, as the States 
develop and implement SMPs. A State and EPA Region could benefit from 
the experience of others, with the cumulative effect of all States and 
Regions reaching a mutual understanding of what works best in general 
situations.
    The Agency could be more specific in advance about certain 
prerequisites of an adequate SMP. For example, EPA might specify by 
regulation different ground-water contamination levels which would 
require State response. These levels would be based on the reference 
points specified in proposed Sec. 152.198. A State would be free to 
specify in its Plan an array of risk-management measures it found 
appropriate to respond to such levels of contamination. In contrast, 
this regulation as presently fashioned only requires a State to 
describe its goals and response program elements in a manner that 
allows the Agency to evaluate their adequacy in relation to the 
adequacy of the other supporting Plan elements.
    Under this alternative, proposed Sec. 152.190(a) would require a 
Plan to establish, within its statement of philosophy and goals toward 
protecting ground water, its ground-water protection objectives in 
terms of EPA's reference point policy. This alternative would also 
change proposed Sec. 152.190(h) to require SMP response-program 
elements to specify prospective risk-management measures in the event 
contamination is detected at or above EPA-specified contamination 
levels. For purposes of eliciting comment, EPA offers the following as 
appropriate levels: (a) 10 percent of a subject pesticide's ground-
water reference point; (b) 50 percent of the ground-water reference 
point; and (c) 100 percent of the ground-water reference point. EPA 
would not pre-specify particular risk-management measures for these 
levels. However, whatever measures that a State does propose would be 
subject to the Agency's evaluation of its adequacy with respect to the 
fulfillment of the general objective of ``preventing unreasonable 
adverse effects ... and protecting the integrity of the ground-water 
resource.''
    Such a specification of program performance objectives would be 
consistent with the EPA's role under the Federal-State partnership, 
that of establishing uniform national policy goals and determining the 
overall regulatory approach. At the same time, States would be free to 
specify the means of meeting those performance objectives, subject to 
Agency review. One benefit of a more concrete specification would be 
the avoidance of misunderstandings between EPA and States: EPA would 
have stated more clearly what it will find acceptable (or unacceptable) 
in defining its requirements in this fashion. Another benefit would be 
greater assurance in the adequacy of a State's plan, since an approved 
Plan would clearly embrace a risk-management scheme tied to a uniform 
set of criteria for action. Regulation would be more protective insofar 
as all States would meet a minimum threshold of risk-management 
measures. This approach might also facilitate EPA review of Plans, by 
eliminating an additional interpretive step, that of determining 
whether the State proposal, in its unique form, conforms with EPA's 
expectations.
    Finally, the Agency recognizes that some potentially affected 
parties have expressed concern that the proposed rule does not offer an 
opportunity to maintain use of a pesticide in the event a state does 
not have an approved SMP, for whatever reason. Therefore the Agency 
requests comment on whether there should be a default provision for 
stringent federal label requirements and/or conditions on the terms of 
registration for these pesticides that would allow continued use in 
lieu of an approved SMP.
    Under this option, the Agency would specify in the final rule the 
national-level requirements that would apply to use of these pesticides 
in States without approved SMPs by the effective date. The Agency has 
established a model for such requirements. In 1994, the Agency granted 
a conditional registration for a new herbicide, acetochlor, for which 
the potential for ground water contamination is a concern. In that 
case, the Agency imposed a variety of restrictions on the use of 
acetochlor, including limiting application to certain soil types, 
prohibiting aerial application, and restricting use to certified 
applicators. In addition, the Agency required the registrant to conduct 
ground-water monitoring at a specified level of effort, and set 
triggers that would result in localized use prohibitions, and 
ultimately national cancellation of the registration if certain 
detection criteria are met. A copy of the specification of the terms 
and conditions of registration for pesticides containing acetochlor, 
which would

[[Page 33275]]

serve as the model for such specifications in the final rule, is 
available in the public docket for this rule. EPA notes that nothing in 
this proposal would preclude registrants themselves from proposing 
additional restrictions on the use of their product to the Agency, 
pursuant to FIFRA section 3(c)(5), in the event a State chose not to 
adopt an SMP. Consequently, this proposal leaves open to registrants 
the option of themselves devising suitable restrictions to prevent 
unreasonable adverse effects on the environment from use of these 
pesticides in the unlikely event that a State chooses not to develop an 
SMP, or that no SMP is approved.
    The Agency would like comments on the following. Would a similar 
approach be appropriate for the SMP chemicals in the event a State 
elected not to develop an SMP for one or more of the chemicals? Should 
the default be available if a State did submit an SMP, but EPA did not 
approve it? What specific precautions and limitations on the label 
would provide adequate protection of ground water in the absence of an 
SMP? Is the Agency correct in proposing to use the specifications of 
the acetochlor registration as the basis of such national-level 
defaults, or are there specific provisions to be added or deleted? 
Should registrants be required to conduct monitoring, and if so, to 
what extent? If there is a registrant monitoring program, should States 
have a role in determining where and how monitoring is carried out? 
Should there be triggers for use prohibition in a State, or only in a 
local use area; if so, what should they be? What would the impact of 
this Federal alternative be on registrants and users? What would the 
effect of this alternative be on State development of SMPs and other 
ground water protection activities or programs?

IV. Risk and Benefit Determination

A. Chemical Background and Characteristics

    1. Uses. The five candidates for SMPs proposed today are similar in 
many important respects. All five are broad-spectrum herbicides 
registered for use on a total of 100 different crops, including most of 
the major field crops grown in the United States (e.g., corn, sorghum, 
and wheat). Together, the five compounds are registered for another 31 
non-crop and non-food uses including ornamental tree, plant, and grass 
sites. Atrazine, simazine and cyanazine are members of the s-triazine 
family of compounds, and are each used to control a variety of 
broadleaf weeds and grasses. Each is used for preplant, preemergence 
and postemergence weed control in crops. Alachlor and metolachlor are 
acetanilide compounds registered for pre-emergent control of broadleaf 
weeds and grasses.
    EPA estimates that between 200 and 250 million pounds of the five 
herbicides, together, are used annually in the United States, which 
represents as much as one-half of total annual agricultural use of 
herbicides. Atrazine, alachlor, and metolachlor are currently ranked as 
the three highest-volume pesticides in use in the United States today, 
with cyanazine ranked fifth. Approximately 150 to 160 million pounds of 
active ingredient (a.i.) of these four pesticides are applied to just 
two field crops: corn and sorghum. Alachlor and metolachlor are also 
commonly applied to soybeans, with 20 to 30 percent of their annual use 
attributable to this crop. Remaining uses of these four herbicides, 
while representing a small fraction of their combined use, still 
represent several million pounds of active ingredient. For example, 1 
to 2 million pounds of cyanazine are used annually on cotton; also, 
another substantial use of atrazine is on sugar cane.
    Historically, use of atrazine was marked by a rapid rise in use on 
row crops through the 1960's, joined by a similar sharp rise in 
alachlor use from 1969 to 1974. At that time, use volumes of each 
leveled off at comparatively high levels (e.g., about 80 million pounds 
annually) as use of cyanazine, and then metolachlor, climbed. Through 
the 1980's, use volumes began to fluctuate, with use of the two older 
chemicals drifting down from combined uses of 170 to 190 million pounds 
per year to levels of 120 to 150 million pounds per year. These general 
declines were matched by corresponding increases in the other two. 
During the first half of this decade, this general trend continues, 
with the exception of a relatively sharp decline in alachlor, and a 
slightly earlier, but more-than-offsetting increase in metolachlor use.
    Simazine stands as the exception to the rest of the candidates with 
respect to use. Only 3 to 5 million pounds of active ingredient are 
used in the United States annually. However, 1 to 2 million pounds (31 
to 42 percent) of simazine is applied to corn, making it the principal 
use of simazine as well. Simazine's remaining uses include crops such 
as alfalfa, seed crops, fruits (apples, citrus, grapes, berries and 
stone fruits, among others) nuts and vegetables. Simazine is also 
registered for several terrestrial non-agricultural uses, as well as 
for aquatic uses (i.e., ornamental ponds).
    2. Other regulatory actions. All five pesticides are subject to the 
reregistration requirements of the 1988 FIFRA Amendments. 
Reregistration of existing pesticide products entails the determination 
that they are eligible for reregistration because: (a) The data 
necessary to determine the pesticide's risk are substantially complete; 
and (b) these data indicate that the pesticide does not cause 
unreasonable adverse effects when the products are used according to 
label directions and restrictions. EPA publishes Reregistration 
Eligibility Documents (REDs), which summarize the studies reviewed and 
the findings reached. A RED for metolachlor has already been published 
(EPA 738-R-95-006, April 1995); a RED for alachlor is scheduled to be 
published in 1996. REDs for the three triazines are not expected before 
the conclusion of the triazines special review.
    In addition to the scheduled reregistrations, four of these 
pesticides are in Special Review. One, alachlor, has been under Special 
Review since 1985. While EPA resolved substantial risk concerns about 
the use of alachlor in 1987, the Agency deferred action on whether the 
risks posed from alachlor in drinking water from contamination of 
ground water required regulatory action. EPA proposes to conclude 
review on these issues with the promulgation of this rule.
    In November 1994, the Agency initiated Special Review (59 FR 60412, 
November 23, 1994) of the three triazine compounds - atrazine, simazine 
and cyanazine - subject to this rule. The Review will address the 
potential overall risks to human health and the environment posed by 
use of these three pesticides, particularly the carcinogenic risks from 
human exposure in drinking water, food, and through handling and 
application of products. Ground-water contamination is part of the 
concern in conducting the Special Review, but only part of the broader 
concerns addressed by it. Therefore, the Agency believes it is 
appropriate to carry out both regulatory proceedings for the triazines 
at this time.

B. Risk Assessment

    1. Adverse health effects-- a. Toxicological endpoints of concern. 
Toxicological endpoints of concern for these five compounds (and their 
metabolites) include carcinogenicity (all five compounds), 
developmental toxicity (atrazine and cyanazine), chronic blood and 
organ toxicity (cyanazine, simazine, alachlor, and metolachlor), and 
cardiotoxicity (atrazine). In the following discussion,

[[Page 33276]]

atrazine, simazine, and cyanazine are frequently referred to together 
as triazines, when the three compounds exhibit similar characteristics 
and effects.
    EPA's Integrated Risk Information System (IRIS) summarizes the 
available information on the toxicological endpoints of concern for the 
five pesticides in today's proposed rule. IRIS data are available to 
the public in both printed and on-line form, and can be accessed by 
telephoning IRIS User Support at EPA's Center for Environmental 
Research Information in Cincinnati, Ohio; (513) 569-7254. The 
discussion below does not include a detailed review of studies showing 
relatively minor adverse effects, such as changes in average body 
weight or the rate of weight gain in developing animals. More extensive 
discussion of the evidence of adverse health effects for each of these 
pesticides has been presented in other documents, e.g., for 
metolachlor, in the recent Reregistration Eligibility Decision document 
and for the triazines, in the Federal Register notice announcing the 
initiation of the triazines Special Review. A more complete description 
of the toxicological evidence to support this rulemaking, drawn from 
these existing sources, is provided in the docket for this regulation.
    All five compounds exhibit adverse effects in animals after long-
term exposure, raising concern about chronic toxicity. For example, 
long-term (usually 2-years) feeding studies with the triazines 
typically show reduced rates of weight gain, and in some cases, 
hematological effects, such as reduced red-cell count. Treatment of 
pregnant animals with all of these compounds shows some developmental 
effects, such as reduced weight gain, or reduced litter size. In 
addition, a 1-year dog study with atrazine showed cardiac effects such 
as increased heart rate and irregular heartbeat. Although these are all 
adverse effects, they do not present the same level of concern as the 
evidence of cancer risk.
    EPA had classified atrazine, simazine, cyanazine and metolachlor as 
Group C (possible human) carcinogens. EPA's Office of Pesticide 
Programs has assigned a numerical cancer potency coefficient, known as 
a Q1*, to each of these chemicals as well (see Table 2 below).
    The triazine compounds have an extremely close structural 
similarity and produce similar tumor profiles in animal bioassays, 
primarily malignant mammary tumors in female rats. In addition to 
animal study data, EPA has reviewed a number of epidemiology studies 
which suggest possible associations between triazine exposure and 
various human health effects, including ovarian cancer, non-Hodgkins 
lymphoma, and birth defects. All of the studies, however, had 
significant limitations, and the Agency does not consider any of the 
suggested health-effect associations to be established by currently 
available information.
    Alachlor was classified as a B2 (probable human) carcinogen by 
virtue of positive results in studies of both rats and mice. At this 
time, however, alachlor is considered to be not classified under the 
current agency system pending further review of scientific issues 
raised by the registrant. Metolachlor has limited evidence of liver 
carcinogenicity in animals.
    The cancer classifications cited here are likely to change in the 
future for several reasons. First, EPA has recently proposed to revise 
its guidelines for the assessment of cancer risks. The new proposed 
guidelines were made available on April 16, 1996, for a 120-day public 
comment period. The issues raised during the comment period will then 
be presented to the Agency's Science Advisory Board. New guidelines are 
likely to become final in 1997. Among other things, the new guidelines 
may change the way the Agency weighs the various kinds of laboratory 
evidence used to identify carcinogenic potential.
    In addition to changing guidelines, the registrants of the triazine 
and acetanilide herbicides have recently submitted new data which they 
believe should reduce concerns about human cancer risks for these 
compounds. It is not clear at this time how this new evidence will 
affect the Agency's risk assessment for these compounds, or how the 
evidence will be evaluated under the new guidelines. In any case, human 
cancer risk is not the only basis for the Agency's concern about these 
chemicals.
    b. Ground Water Reference Points. Table 2 of this Unit displays the 
relevant summary toxicological data for these five compounds. The 
derivation of the Ground Water Reference Points shown in Table 2 is 
discussed below.
    The Ground Water Reference Point for a compound is a representation 
of the compound's toxicity, expressed in units corresponding to 
environmental exposure. The Reference Point provides a means to assess 
the significance of known or anticipated concentrations that occur in 
ground water. As described in Unit II. of this preamble, the Agency 
normally will use MCLs established under the Safe Drinking Water Act 
(SDWA) as reference points. MCLs are derived from Maximum Contaminant 
Level Goals (MCLGs), which is that concentration, ``... at which no 
known or anticipated adverse effects on the health of persons occur and 
which allows an adequate margin of safety'' (SDWA section 1412(b)(4)). 
In most cases an MCLG is based on the Reference Dose (RfD) for the 
compound, to which standard conversion and uncertainty factors have 
been applied to account for anticipated drinking water exposure. For 
compounds classified as Group C carcinogens, EPA also applies a 10-fold 
uncertainty factor to provide for an additional margin of safety. The 
enforceable MCL, set simultaneously with the MCLG, is set ``as close to 
the [MCLG] as is feasible'' (Ibid). In the case of B2 carcinogens, 
Agency policy has been to set the MCLG at zero. The corresponding MCL 
is then set at a finite level by evaluating the performance of feasible 
water treatment and analytic technology. More information on EPA's 
methodology for setting MCLs and MCLGs is available in the final rule 
which established MCLs for atrazine and alachlor (56 FR 3526, January 
30, 1991).
    The following Table 2 is a summary of the human health risk posed 
by these five chemicals:

  displayed at left.                                                                                                                                    

    In the absence of MCLs, EPA will use a Health Advisory (HA) to 
establish Ground Water Reference Points. HA levels are established 
using the same methodology used for non-zero MCLGs. MCLs have been 
established for atrazine, simazine, and alachlor, and these are Ground 
Water Reference Points for these compounds. The Reference Points for 
cyanazine and metolachlor are based on HA levels.
    In summary, the Agency feels that there is sufficient evidence to 
concluded that each of the five compounds addressed in today's rule may 
cause serious, irreversible adverse effects to the health of persons, 
if any of the compounds were present in drinking water at or above 
particular concentrations or at other concentrations for a prolonged 
period of time. In fact EPA has set drinking water standards for three 
of the compounds in this proposed rule, in order to prevent the onset 
of such effects as a result of drinking water in Public Water Systems 
(PWSs). The Agency has set Health Advisories for the other two 
compounds, in order to allow PWSs to evaluate and avert potential 
adverse effects to human health should these compounds be encountered. 
MCLs for these two compounds may also be developed at a later date.
    2. Environmental effects. In addition to their potential for 
adverse human health effects, EPA is also concerned about the potential 
adverse effects of these compounds: (1) On specific non-target plants 
and animals, including the potential economic impact associated with 
adverse effects on both commercial crops and animals; and (2) on 
ecosystems as a whole.
    EPA has far less specific data on the potential adverse ecological 
effects of these five compounds than for adverse health effects. 
However, both the chloro-triazines and the acetanilides inhibit 
photosynthesis in plants and may have phytotoxic effects to terrestrial 
and aquatic plants.
    Of these chemicals, atrazine has been the most fully studied and 
characterized for environmental effects. In comparative laboratory 
acute toxicity testing, atrazine exhibits moderate toxicity to birds, 
mammals, fish, or aquatic invertebrates. Studies representing simulated 
field conditions have also been conducted. For aquatic plants, 
available information indicates that short-term exposure to relatively 
low levels of atrazine (for example, concentrations of approximately 20 
g/l) can produce phytotoxic effects from which plant 
populations will not recover. Information on simazine and cyanzine 
indicate that longer-term exposure at even lower levels, in the range 
of about 5 g/l, can also inhibit plant reproduction.
    Substantial risks can be anticipated from continuing off-target 
movement of these five compounds and consequent exposure of aquatic 
organisms and ecosystems. Contamination of ground water can be a 
mechanism of transport for these compounds to surface water, since 
ground water provides a significant source of recharge for many bodies 
of surface water. While it is difficult to segregate potential risks 
from the presence of these compounds in ground water from those that 
might result from other means of environmental transport such as 
runoff, the risks are real enough to be of concern.
    In addition, there is a considerable body of monitoring data 
available on these five pesticides, primarily in the mid-western 
``corn-belt'' States where they are most heavily used. These data 
demonstrate that residues of these five pesticides can be detected in 
both ground and surface waters in areas of heavy use, at levels which 
frequently approach, and sometimes exceed, the MCLs or HAs. (Data for 
ground-water occurrence are discussed in more detail below).
    Thus, the Agency feels that there is sufficient evidence to infer 
that present environmental levels of these herbicides from various 
environmental transport mechanisms, including leaching to ground water, 
pose substantial risks to aquatic plant life, both in the form of 
outright phytotoxicity and in the longer-term and more subtle effect of 
inhibiting plant reproduction. If such effects occur in an aquatic 
environment, the effects on the ecosystem could be profound. Complete 
loss of habitats may occur. Even partial loss of food supply or 
protective cover can result in significant impacts on other aquatic 
organisms. Herbicides in the aquatic environment could destroy the food 
source for higher organisms, which may then starve. Herbicides may also 
reduce the amount of vegetation available for protective cover and the 
laying of eggs by aquatic species. Submerged aquatic vegetation is the 
nursery for commercial and recreational species. As such, drastic loss 
of submerged aquatic vegetation in rivers or estuaries is a serious 
environmental concern. Some experts believe that herbicide related 
ecosystem damage may already be occurring in locations such as the 
Chesapeake Bay and parts of the Mississippi delta.
    EPA has drafted a Water Quality Criteria document for atrazine that 
proposes to establish a fish-protection level of 22.7 g/l 
(measured as a 4-day average concentration over a 3-year period), below 
which ``freshwater aquatic animals and their uses should not be 
affected unacceptably ...,'' adding a peak 1-hour concentration limit 
of 571.9 g/l (not to be exceeded more than an average of once 
in a 3-year period). For the protection of freshwater aquatic plants, 
atrazine concentrations should not exceed 2.0 g/l for any 4-
day period within a 3-year period.
    The total risks of these five pesticides to aquatic ecosystems are 
beyond the scope of the regulatory action being proposed today. These 
ecological risks involve, in addition to contamination of ground water, 
contamination of surface water through many alternative routes, such as 
runoff through the unsaturated zone to a nearby water body.
    Ground water SMPs cannot be expected to address all of these 
potential routes to surface water contamination that may occur as a 
result of the legal use of these five pesticides. However, certain use 
management measures implemented by States as part

[[Page 33278]]

of their ground-water Plans may provide some ancillary protection 
against such surface-water contamination. At a minimum, no SMP will be 
approved that contains a preventive measure that will clearly increase 
the likelihood that surface water will be adversely affected as a 
consequence (see Unit III.C.7. of this preamble, and Guidance, pp 3-15-
6, Ref. 18).
    3. Ground water contamination potential-- a. Persistence and 
mobility. EPA requires that all pesticide registrants submit data on 
the physical and chemical characteristics of a pesticide in order to 
characterize its environmental fate. These data are generated through a 
battery of basic laboratory tests and limited field studies as 
specified in 40 CFR 158.290, otherwise known as the ``Subpart N'' 
Guidelines. Two important factors, known as persistence and mobility, 
are particularly relevant in predicting whether a substance has the 
potential to reach ground water.
    Persistence refers to a substance's relative resistance to 
environmental processes which tend to break that substance down, and 
thus to the length of time that substance can exist in the environment. 
Persistence is generally measured as a half-life (t1/2 or 
t50), or the length of time in which 50 percent of an 
environmental concentration disappears as a result of transport or 
degradation. Mobility refers to the potential for an ingredient to move 
away from the point of application, and is typically represented by a 
substance's resistance to binding to soil or soil constituents. 
Measures such as the soil-water partition coefficient (kd) or the 
carbon-referenced sorption coefficient (Koc) are used to indicate a 
substance's binding potential.
    A pesticide that is relatively persistent and mobile would tend to 
remain in the subsurface environment, be present at substantial 
fractions of the original environmental residue, and reach underlying 
aquifers relatively quickly. Together, persistence and mobility are 
referred to as a pesticide's leaching potential.
    (i) Parent compounds. Table 3 of this Unit contains a summary of 
the persistence and mobility characteristics for the five pesticides 
subject to today's proposed rule. The Table shows chemical-specific 
values for the seven parameters that EPA uses to evaluate a pesticide's 
propensity to reach ground water. These values, generated from the 
combination of laboratory and field studies EPA requires for 
registration, are compared against the values (displayed in the Table) 
that EPA regards as indicative of leaching potential.
    EPA proposed these values in a previous proposed rulemaking (see 56 
FR 22076, May 13, 1991) as criteria indicating a reasonable potential 
for reaching ground water on a widespread basis, for purposes of 
considering a pesticide for restricted use classification. While EPA is 
not proposing to apply these criteria to determine whether a pesticide 
needs to be subject to an SMP, the Agency provides the information as 
evidence of the pesticides' leaching potential. As indicated in Table 
3, all five pesticides display persistence and mobility characteristics 
exceeding the values EPA considers evidence of a propensity to leach. 
In the event EPA were to classify the pesticides for conventional 
restricted use independently of the regulatory action referred to 
above, the Agency believes that this evidence, combined with the 
detections of the parent compounds in ground water to date, would not 
only meet the EPA's final criteria for restricted use for ground-water 
concerns, it would establish that these pesticides could pose a serious 
hazard to the environment in the absence of the mitigation provided by 
restricted use classifications. Such evidence would be sufficient for 
EPA to propose restricted use classification for simazine and 
metolachlor, the two pesticides subject to today's proposed rule not 
now classified as such, under the existing regulations for restricted 
use classification (c.f., 40 CFR 152.170(d)).
    As shown in Table 3 below, all five pesticides are resistant to 
chemical hydrolysis, indicating their likely environmental persistence. 
The term ``stable'' as used in Table 3 means the compound was observed 
to degrade more slowly than the rate of degradation specified as the 
critical value in the criteria column, i.e., a decrease of 10 percent 
or more in the tested concentration of a substance over 30 days 
duration of a hydrolysis test.

    (ii) Degradates. In the case of all five of these pesticides, the 
leaching potential of metabolites and/or degradates are an additional 
concern. For example, since the 1980s investigators have reported 
detections of triazine degradates as well as the parent compounds in 
both ground and surface water. Alachlor and metolachlor also have 
various degradation products which may be mobile and persistent enough 
to leach.
    b. Occurrence of ground water contamination. Registrants, States, 
the United States Geological Survey (USGS), and EPA's National 
Pesticide Survey are all sources of ground-water monitoring data (Refs. 
10 and 14). In reviewing monitoring data, EPA's Office of Pesticide 
Programs (OPP) records occurrence in ground water as the number of 
discrete locations where a pesticide ingredient was detected at least 
once. Multiple detections at the same well over an interval of time 
from repeat sampling are not counted as separate detections in the main 
data collections cited below. EPA recognizes that this procedure could 
function to put wells with only a single detection from repeated 
sampling on an equal footing with wells in which occurrence is 
regularly found. Specified detection limits are a measure of the 
sensitivity of the analyses. Such sites are typically water-supply 
wells or, to a lesser extent, ground-water monitoring wells. OPP uses 
the term ``wells'' to refer to occurrence sites.
    EPA's sources of ground-water data include: (1) The Pesticides in 
Ground Water Data Base (PGWDB), a data base containing the information 
described above, and periodically up-dated by OPP (Ref. 15); (2) EPA's 
National Pesticide Survey (NPS; Refs. 10 and 14), a statistically 
designed one-time survey of existing wells, including both community 
wells and rural domestic wells nationwide, (data not included in the 
PGWDB); (3) Monsanto's National Alachlor Well Water Survey (NAWWS) 
(Ref. 3)-this survey was limited to alachlor use areas, and sampling 
was limited to private rural domestic wells; (4) Ciba-Geigy (now Ciba 
Plant Protection) performed a Large-Scale Retrospective Ground-Water 
Study for Metolachlor in Four Areas of the U.S. (Ref. 2) with high 
metolachlor use and/or high vulnerability to contamination of ground 
water by pesticides; and (5) a number of State-initiated ground water 
monitoring programs. All of these information sources are described in 
greater detail in the ``Water Resources Impact Analysis for the 
Triazine Herbicides'' (Ref. 20). Tables 4 through 8 of this Unit 
summarize information developed from those sources.
    (i) Atrazine and triazine metabolites-- (a) Atrazine parent. The 
evidence of atrazine occurrence is summarized in Table 4 of this 
preamble. Atrazine was the third most often detected of all currently 
registered pesticides in OPP's Pesticides in Ground Water Data Base, 
after aldicarb (and its metabolites) and carbofuran (and also after two 
banned pesticides, EDB and DBCP).
    Atrazine was found in the National Pesticide Survey, as shown in 
Table 4, and in the Monsanto NAWWS Survey. In particular, in the 
latter, atrazine was the most frequently found pesticide, estimated to 
be present in 12 percent of wells in the alachlor use area. The study 
estimated that concentrations will exceed the MCL of 3 g/l in 
0.1 percent of the wells in the alachlor use area.
    (b) Chloro-triazine degradates and other triazine occurrence. There 
are fewer data on degradates in ground water than for the parent 
triazines; cyanazine and simazine degradates in particular are rarely 
looked for. The Pesticides in Ground Water Data Base contains 
detections of two chloro degradates of atrazine at concentrations of 
0.05 to 2.86 g/l. The NPS analyzed for only one degradation 
product of atrazine (desethyl atrazine) and the detection limit for 
that product was relatively high (2.2 g/l); the NAWWS did not 
analyze samples for degradation products of atrazine or the other 
triazines at all. Two of the three major chloro-triazine degradates of 
atrazine were analytes in Iowa's SWRL study, the results of which are 
shown in Table 4. The Wisconsin Rural Well Study provided significant 
information on the occurrence of atrazine degradates. Almost 92 percent 
of wells that were resampled in phase 2 of the study contained a 
combination of parent and degradate residues. Overall, degradates found 
in the Wisconsin Rural Well Survey accounted for 67 percent of total 
triazine residues.
    Results of a recent USGS study of herbicides and nitrates in near-
surface aquifers in the mid-continent United States (Kolpin, et. al., 
1994) reported that desethyl atrazine was the most frequently reported 
compound (18.1 percent of wells), followed by atrazine (17.4 percent), 
and desisopropyl atrazine (5.7 percent). The detection of total 
residues was 25 percent more than the detection of atrazine alone. This 
study differs from the NPS and NAWWS studies in that it sampled ambient 
ground water, not just ground water used as a source of drinking water.
    Finally, the advent of new analytic techniques such as the rapid, 
highly sensitive and relatively cheap detection methods based on 
enzyme-linked immunosorbant assay (ELISA), has allowed monitoring 
studies of ``total triazine'' levels. While typically employed as a 
``screen,'' with detections subsequently analyzed by conventional 
methods to identify and quantitate specific compounds, the PGWDB 
contains reports of one State's findings of undifferentiated ``total 
triazine'' occurrence. In 1990, Ohio reported monitoring at 863 sites, 
with 48 detections at concentrations ranging from 0.1 to 5 g/l 
(Baker, et. al., ``Nitrate and Pesticides in Private Wells of Ohio: A 
State Atlas,'' Heidelberg College, (Ongoing)).
    (ii) Simazine. The evidence of simazine occurrence in ground water 
is summarized in Table 5 of this preamble. Simazine was the eighth most 
often detected pesticide in OPP's Pesticides in Ground Water Data Base 
and the sixth most frequently detected of the currently registered 
analytes. In Kolpin, et. al. (1994) simazine residues were detected in 
1.0 percent of the wells sampled in the mid-continental U.S.
    (iii) Cyanazine. Less monitoring data exist for cyanazine in ground 
water than for atrazine and simazine. Table 6

[[Page 33280]]

summarizes data on monitoring results for cyanazine. Cyanazine was the 
15th most often detected pesticide in OPP's Pesticides in Ground Water 
Data Base, with detections in 15 out of 27 States in which samples were 
collected. Additionally, cyanazine has been reported to be found at 
concentrations greater than 0.1 g/l (or 10 percent of its reference 
point of 1 g/l) in more than 80 additional wells in 12 States.
    No detections were reported in the NPS; however, the minimum 
detection limit in that study was 2.4 g/l whereas the likely 
MCL for cyanazine is 1 g/l. NAWWS estimates that detectable 
levels of cyanazine are expected to occur in 0.3 percent of rural 
domestic wells in counties where alachlor is used. As is the case for 
simazine, this may not be a good national estimate of cyanazine 
occurrence because the use areas of cyanazine and alachlor may not 
closely coincide. The detection limit for cyanazine in this study was 
0.1 g/l; whereas the detection limit for the other 4 analytes 
was 0.03 g/l. This higher detection limit undoubtedly reduced 
the number of observed positives. No estimate was given for cyanazine 
concentrations that exceed 1 g/l. NAWWS did not analyze water 
samples for degradation products of cyanazine. Cyanazine was not an 
analyte in the Ciba-Geigy Large-Scale Retrospective Ground-Water Study. 
As regards State surveys, cyanazine was the 5th most frequently 
detected pesticide in Iowa's SWRL study (of the 27 pesticide analytes). 
Cyanazine was not an analyte in the Wisconsin study and no confirmed 
detections of cyanazine are reported in the California database. 
Cyanazine was detected in 0.7 percent of the wells sampled in the USGS 
study by Kolpin et. al. (1994).
    (iv) Alachlor (and metabolites). Table 7 of this preamble 
summarizes the information available to the Agency regarding alachlor 
occurrence in ground water. Alachlor is the seventh most often found 
pesticide in the Pesticides in Ground Water Database, with only 
aldicarb (and its metabolites), carbofuran, atrazine and oxamyl among 
the currently registered pesticides detected more often. In addition, 
alachlor has been reported to be found at concentrations greater than 
0.2 g/l (or 10 percent of its reference point) in more than 
350 wells in 21 States.
    The NPS estimated that 3,140 (or <0.1 percent) rural domestic wells 
contained alachlor at levels above the Reference Point of 2 g/
l. There were no detections of alachlor in community water system 
wells. The NAWWS estimated that alachlor occurs in approximately 1 
percent of rural wells throughout its use area. Less than half of these 
detections are at levels exceeding 0.2 g/l (or 10 percent of 
the MCL). Alachlor is estimated to occur at levels exceeding its 2 
g/l MCL in 0.02 percent (or approximately 1200 wells) of the 6 
million rural wells in the alachlor use area. There were no degradation 
products analyzed in either the NPS or the NAWWS. Alachlor residues 
were detected in 1.7 percent of the wells sampled by USGS (c.f., 
Kolpin, 1994). The State survey results are summarized in Table 7. In 
addition, several investigators (including USGS) have reported finding 
a major metabolite of alachlor, t-sulfonic acid in ground-water samples 
(c.f., Ref. 3).
    (v) Metolachlor. Metolachlor was the 12th most often found 
pesticide in the OPP Pesticides in Ground Water Database (see Table 8). 
Metolachlor was also reportedly found at concentrations exceeding 7 
g/l (or 10 percent of its reference point) in 19 wells across 
6 States. NAWWS estimates that metolachlor has a detection frequency 
near 1 percent in the surveyed ``alachlor use area.'' Less than half of 
the metolachlor detections are at levels exceeding 0.2 g/L. 
The average detection limit was 0.03 g/L.
    Results from the Ciba large-scale retrospective study of 
metolachlor indicate that metolachlor was detected in 89 of 920 samples 
(or 10 percent), and 39 of 240 wells (or 16 percent). The screening 
level was 0.1 g/l. Detections ranged from 0.1 to 88 
g/l with half of these detections at concentrations of 0.1 to 
0.5 g/l. None of the detections in this study exceeded the 
Health Advisory (HA) of 70 g/l. USGS (Kolpin, 1994) reported 
that 2.7 percent of the wells sampled in the mid-continental United 
States contained metolachlor residues. The following five tables 
(Tables 4 through 8) summarize the data on occurrence for each of the 
five pesticides.

    c. Conclusions--Ground water contamination potential. The five 
pesticides selected in today's proposed rule exhibit persistence and 
mobility characteristics that suggest the capacity to reach ground 
water on a widespread basis. This potential is confirmed by the record 
of occurrence produced from ground-water monitoring efforts. Each of 
the five has been detected hundreds of times in many States, indicating 
the breadth and magnitude of ground-water contamination potential. 
Moreover, each has been detected at concentrations exceeding its 
respective reference point in multiple locations, in different States, 
and across a variety of hydrologic and geologic conditions. This, and 
the fact that many more detected concentrations of each are within one 
order of magnitude (i.e., 10 percent or more) of each reference point, 
confirms that each pesticide exhibits the capacity to reach ground 
water at concentrations exceeding health-based standards. To EPA's 
knowledge, point sources do not explain the range and number of these 
occurrences. All five can be reasonably expected to contaminate ground 
water at or above their respective reference points. EPA has reached 
the tentative conclusion from this data that continued use of these 
pesticides without further controls and protective measures constitutes 
a clear risk of continued ground-water contamination.
    4. Risk conclusions. In summary, EPA concludes that exposure from 
these pesticides may present the potential for adverse human health and 
environmental effects associated with exposure from these five 
pesticides.
    These five, while they may differ among themselves in the frequency 
and severity of prior detections in ground water, entail a significant 
number of detections in multiple States. Among currently registered 
pesticides, only these five and aldicarb, which is being addressed by 
other regulatory means, have been detected above their respective 
reference points in three States or more. Second, these five share a 
substantial overlap in use sites and crops, such that each pesticide 
could represent a significant alternative to the use of one or more of 
the others. This latter circumstance plays a significant role in EPA's 
decision to subject all five to SMPs. Leaving one or more of these free 
from State management measures might constitute an incentive for users 
to substitute that pesticide for one of those subject to SMPs. EPA's 
analysis of the contamination potential of these pesticides suggests 
that such a course might only increase the occurrence of the excluded 
pesticide(s) to a frequency and severity that would rival that observed 
for atrazine and alachlor. The practical effect of such an exclusion 
might be to worsen the overall quality of the ground-water resource.
    EPA has also considered the potential impact associated with the 
increased use of substitute pesticides that may result from reduced use 
of the five under consideration here. This issue includes two separate 
considerations. The first is the possibility that increased ground-
water contamination will result from increased use of substitute

[[Page 33284]]

pesticides not subject to SMPs. EPA acknowledges that there is a 
likelihood that other pesticides will be used in substitution for these 
five in cases where State measures constrain triazine and acetanilide 
use. EPA has analyzed the likelihood for such substitutions in its 
Regulatory Impact Analysis (see Unit VIII. of this preamble); in this 
analysis the Agency has identified the likely substitute pesticides for 
a substantial variety of crops and other uses. Only a few of the 
prospective substitutes exhibit similar persistence and mobility 
characteristics; upon closer examination, moreover, it is unlikely that 
any of the prospective substitutes exhibit as severe a potential for 
ground-water contamination as these five candidates. None of the 
prospective substitutes have been detected in ground water to the 
extent and frequency as these five. Given the substantial evidence 
summarized in here that these five are the largest ground-water 
contamination risks of any pesticides in current use, EPA concludes 
that it is has no reason to anticipate that increased use of 
substitutes will result in a greater risk to ground water for the 
foreseeable future.
    The other consideration is that the increased use of substitutes 
might indirectly increase net risks, because of greater risks through 
other routes of exposure, such as dietary and worker exposures. This is 
a considerably more complex question. EPA believes that these risks 
will not measurably rise because of the use of anticipated substitutes. 
EPA reaches this conclusion, considering: (1) There will be 
comparatively little substitution of use of these pesticides with 
potentially more dangerous alternatives (at least compared to an 
outright cancellation), since EPA's analysis of impacts concludes that 
State measures will permit substantial continuing use of the five 
pesticides in question; and (2) none of the anticipated substitutes 
pose particularly elevated risks for these other exposure routes at 
reasonably expected increased levels of use. EPA has confidence that 
none of the substitutes are particularly more toxic, overall and in 
relation to particular endpoints, than the five pesticides in question. 
For example, none of the prospective substitutes are in Special Review, 
for health concerns as the triazines are.
    a. Metabolites. At this time EPA does not intend to require that 
State Plans provide for monitoring degradates of these five pesticides. 
However, EPA would like comments on: (1) Whether it should require 
State submissions to address selected metabolites of toxicological 
concern; (2) what specific metabolites should be addressed by SMPs; and 
(3) what specific SMP provisions should apply to the metabolites.
    The Agency notes that relatively inexpensive screening methods are 
available for all five of the parent compounds, and for many of their 
metabolites. Thus, a State may choose to include degradates in their 
monitoring plan, as some already do. Moreover, if additional 
information about some or all of these degradates raises concerns in 
the future, EPA may revisit this issue. The availability of practical 
analytical methods would be an important consideration in asking States 
to include degradates in their monitoring plan.

C. Costs and Benefits

    The following section completes EPA's proposed determination that 
the five pesticides may present an unreasonable risk to the environment 
without additional management measures to reduce the chances of their 
contamination of ground-water resources, by evaluating the risks 
represented by that contamination potential in light of the social and 
economic costs that SMPs represent. Costs and benefits under 
consideration are conceived on the broadest, most inclusive fashion 
(i.e., beyond the direct costs of the SMPs envisioned by this proposed 
rule and the benefits of averting human health risks represented by 
ground-water contamination). The remainder of this section summarizes 
the data, analysis and conclusions contained in the Agency's draft 
Regulatory Impact Analysis (RIA) prepared for this rule pursuant to 
Executive Order 12866 (see Unit VIII. of this preamble). Those 
interested in a more detailed analysis of costs and benefits should 
refer to that document.
    The assessment of risks and benefits associated with the decision 
to make these five pesticides subject to SMPs as a regulatory 
requirement takes into account the Agency's policy objective of 
prevention, i.e., to act in order to avert reasonably expected adverse 
effects to human health or the environment before they may occur. EPA 
must exercise its judgement on the basis of an analysis of the 
respective costs and benefits of regulatory action in a manner that 
takes into account the considerable uncertainty surrounding both. This 
entails acting on the basis of less tangible evidence of risk and 
considerable degree of uncertainty about both existing and future 
ground water contamination and its consequences, and taking 
considerable allowance of these uncertainties. It also entails weighing 
a detailed and quantified analysis of costs against an array of 
prospective benefits, many of which are difficult to describe in 
quantitative terms. Such a comparison, between what appear to be 
tangible costs and more intangible benefits, presents well-recognized 
analytic difficulties. Care must be taken not to let the quantified 
factors override consideration of important qualitative factors. In 
other words, SMPs will be justified based on a reasoned determination 
that the benefits (generally conceived and including elements difficult 
to quantify) justify the cost impacts associated with SMPs.
    In developing the Strategy (Ref. 12) EPA evaluated a range of 
available regulatory options in addition to the State Management Plan 
approach. Specifically, EPA compared three general approaches in a 
companion document to the Strategy, the ``Pesticides and Ground-Water 
Strategy: A Survey of Potential Benefits'' (February 1991; Ref. 13). 
This analysis is discussed in Unit IV.D., of this preamble.
    In the interests of presenting as full and honest a 
characterization of risk and benefit as possible, the Agency will also 
point out: (1) The relative magnitude of uncertainty regarding the true 
value of a quantity or attribute that EPA is estimating in its 
analysis; and (2) the reasons for believing that any specific estimate 
or characterization may overstate or understate the true value of such 
a quantity or attribute.
    1. Costs. EPA identifies four general areas where some level of 
adverse economic impact (i.e., both direct and indirect costs) could 
result from regulatory action in response to ground water concerns. 
Federal program costs are the attributable costs of developing and 
justifying regulatory action regarding ground-water protection, 
including the assembly and evaluation of ground-water risk data, as 
well as expenditures relating to implementation of protection measures. 
Current expenditures include the cost of ongoing regulatory and risk 
assessment activities pertaining to ground-water protection in the 
pesticides program and grants to State pesticide programs to help 
sustain the cost of ground-water protection activities and, in 
particular, the development of ``generic'' SMPs.
    EPA program costs are subdivided into headquarters (HQ) program 
costs and regional costs. As should be evident from the description in 
Unit II. of this preamble, the larger portion of EPA's effort will 
reside with the Regions. EPA estimated its regional-program costs by 
estimating a per-SMP average level of

[[Page 33285]]

effort and multiplying by the expected number of State Plans that are 
currently anticipated for these five pesticides. EPA's analysis is 
calculated on the expectation that 236 Plans will be submitted. This 
translates into an annualized cost of $1.1 million for regional 
activities. EPA estimates its annual HQ program costs will range 
approximately from $413,300 to $437,000 (in current dollars) for the 
first 3 years after promulgating this rule, with costs decreasing to an 
average of $160,600 annually thereafter.
    The margin of uncertainty for EPA's estimate is relatively small 
(mostly reflecting the relatively small dollar estimate) and relatively 
insignificant with regard to its potential impact on EPA's decision. It 
is difficult to determine whether EPA's estimate tends to understate or 
overstate the likely actual value of Federal costs, in part since a 
substantial proportion of the costs are part of ongoing regulatory 
activities. However, any error in EPA's estimate (because of these 
uncertainties) is probably more likely to understate the estimate 
slightly.
    State program costs are the estimated State expenditures for 
implementing Federal ground-water protection actions. These include the 
costs of developing five pesticide-specific SMPs and of implementing 
and enforcing elements of approved Plans and represent a substantial 
level of expenditure.
    Because the scale of State Management Plans is contingent upon 
pesticide usage and aquifer sensitivity-- which will vary not only 
between States but also within a given State--the costs of developing, 
implementing, and enforcing SMPs are particularly difficult to 
generalize. In calculating the costs of SMPs, it is reasonable to 
assume that costs will vary directly with the scale of a State's plan. 
Finally, several additional factors will influence the eventual costs 
of a State's plan. These include: the risk mitigation options available 
to State planners; the role of coordination between State agencies and 
other governmental bodies; the shifting of costs to registrants; and 
technological innovations that may lead to decreasing costs over time. 
States have reported (in the process of developing ``generic'' SMPs) a 
broad range of anticipated costs (from as little as $17,000, to write a 
generic plan to over $1 million, counting in full the conduct of 
vulnerability assessments, ground-water monitoring and data base 
management), corroborating the assumption of variable State costs.
    EPA made some critical simplifying assumptions in developing its 
cost estimates: (1) That ``States'' (including territories and some 
Indian tribal authorities) would develop and submit State Plans for all 
or most of the five pesticides in question before the effective date of 
the rule; (2) that the Plans would represent an adequate level of 
protection, i.e., would be approved by EPA; (3) that some States would 
be obliged to develop SMPs that entailed extensive protection programs 
for one or more of the five pesticides, that others would have to 
develop Plans with some additional protection and that still others 
would have to do little more than minor amendments to their ``generic'' 
SMPs to provide for future use of any of the five chemicals (based on 
an analysis of the current use patterns of the five pesticides); (4) 
that virtually all States would submit Plans that would consolidate the 
activities related to any and all pesticides as much as possible, so 
that substantial costs in ground-water vulnerability assessment and 
monitoring, for example, would be shared and not duplicated among 
individual-pesticide proposals - a reasonable assumption in this case, 
considering in particular the common use areas among these five 
candidates and their concentration in areas of high-intensity field-
crop agriculture that would otherwise be of high State concern in any 
case; and (5) that the mix of ``extensive'' and less-extensive State 
Plans would entail a level of effort that could be estimated on the 
basis of a ``model'' SMP activity, that could in turn be extrapolated 
from analysis of existing State programs, ``generic'' SMP submissions 
and the requirements of pesticide-specific SMPs embodied here in 
today's proposed rule and in the Agency's Guidance. The Agency regards 
this last assumption as particularly conservative, since the Agency 
expects that a significant number of actual Plans will turn out to be 
of the less-extensive variety. Pricing every Plan on the basis of a 
``model'' Plan will significantly overstate the true costs, since the 
Agency constructed the ``model'' to represent a relatively extensive 
level of effort.
    EPA developed its aggregate State-cost estimate by means of using 
an existing State plan (Wisconsin's) as a model or surrogate for 
individual State plans. Wisconsin's program was chosen as 
representative for several reasons; its ability and readiness to share 
its data on program development and costs; and its exemplary nature (in 
terms of level and extent of commitment and exercise of risk-management 
measures). Furthermore, Wisconsin falls into the range of moderate 
vulnerability as measured by several macro-level ground-water 
vulnerability indices. However, this latter circumstance is in itself 
not the consummate proof of Wisconsin's representativeness (or even 
adequate characterization of Wisconsin's relative ground-water 
sensitivity), since State situations in terms of vulnerability are so 
diverse as to preclude the classification of any State as ``average.'' 
Finally, EPA did not view the Wisconsin program as the maximum effort a 
State might have to exert: not only has the program dealt primarily 
with a few, particular pesticides, but it terms of general ground-water 
contamination risk, Wisconsin may not represent the greatest degree of 
vulnerability.
    EPA, in its analysis, took into account both the one-time costs of 
a Wisconsin-type program (annualized over either a 5- or 10-year 
period) and estimated annual incremental costs to arrive at a range of 
estimated annual State expenditures. One reason for using Wisconsin's 
experience as a model is the fact that it has performed some of the 
initial activities necessary to implement an SMP, enabling the Agency 
to model such activities as the establishment of pesticide usage 
surveys, vulnerability assessment, soil susceptibility mapping, other 
data base creation, monitoring (establishing and sampling sites), 
maintenance of records, personnel, public awareness and education, and 
other miscellaneous costs of plan development.
    EPA estimates State programs on the average may annually cost in 
the range of $250,000 to $750,000 during the first several years of 
implementation, with $500,000 as the average annual cost. Successive 
SMPs required by the Agency will undoubtedly require less new effort by 
the States, so that incremental costs would be expected to decline over 
the long run. EPA took this expectation into account in its estimate of 
State program costs, projecting that each State, in developing multiple 
SMPs for these five pesticides, would incur some economies by 
developing Plans with common elements. Therefore, national costs were 
calculated by positing one per-SMP cost estimate ($500,000) for a 
single Plan, and fractional estimates for accompanying Plans. 
Calculated on this basis, if States and territories were to implement a 
total of 236 SMPs (EPA's current estimate of States' intentions), their 
total annual cost of implementing this regulation would be $ 59.9 
million.
    The Agency wishes to emphasize that the use of a ``model'' level of 
effort, based largely on one State's experience, is for purposes of 
estimating the costs

[[Page 33286]]

and benefits of this proposed rule. The analysis is not meant to 
represent pre-conceptions about the contents of State submissions. 
State Plans could depart substantially from the details presented in 
the ``model.'' Such differences could be caused by the State's 
particular situation (varying in size, ground-water vulnerability, and 
pesticide use patterns from the model) or by an innovative approach 
that EPA has not anticipated. These Plans would be found adequate to 
the extent States could demonstrate to the satisfaction of the 
reviewing Region that they assure adequate protection. At the same 
time, the Agency believes that it has projected the particulars of the 
``model'' Plan in a manner that depicts the kind of effort necessary to 
meet the objectives of this proposed rule. To that extent, EPA offers 
the State-cost analysis as a reasonable basis for evaluating the cost 
and benefit of this rule.
    Moreover, the Agency wishes to emphasize that the estimate of $59.9 
million is the annual average of aggregate State costs over a 10-year 
period. As such, it represents: (1) The amortization of high one-time 
costs, such as drilling monitoring wells or performing baseline 
vulnerability assessments; and (2) several years of operation of fully-
developed, mature State programs. Under no circumstances should the 
figure be construed to be the immediate, first- (or even second-) year 
costs the States will incur. As stated in Unit III. of this proposed 
rule, EPA anticipates that States can be expected to have to phase in 
``capital'' elements of an SMP (e.g., the development of monitoring and 
vulnerability assessment activities).
    EPA's assumption of broad State participation (that all States will 
develop Plans for most of the five pesticides, and that many will 
develop Plans for all five) may appear to be particularly tenuous, 
since there is no compulsion on the States to develop such Plans, 
beyond the loss of the legal use of a pesticide within the State. The 
consequences of error in this assumption are two-fold with respect to 
estimating costs: (1) EPA's estimate of State costs may overestimate 
actual State costs, because the Agency has over-estimated State 
participation; but (2) in that event, EPA's estimate of user impacts 
might be low. Since the absence of an acceptable SMP would result in 
prohibition of a pesticide's use in a State, more user impacts may 
result than EPA has estimated. The fact that the effects of error in 
this assumption are at least potentially offsetting reduces the 
Agency's concern.
    EPA has confidence in the validity of assuming maximum State 
participation, however. First, the Agency believes the States have 
strong incentive to avoid these increased impacts to its own users by 
developing Plans. This belief is bolstered by the strong evidence of 
the States' interest in assuming the responsibility for managing 
pesticide use to protect ground water (for example, the near-universal 
acceptance of grants and development of ``generic'' SMPs). At the same 
time, EPA has little alternative to such an assumption. EPA does not 
have any basis for estimating which or how many States might fail to 
implement plans, beyond current informal communications between EPA 
regions and the States. Finally, it seems reasonable to assume the 
States least likely to participate are those with the least incentive 
to do so (i.e., those with little or no current or projected use of the 
pesticides), so that their non-participation would have comparatively 
little effect on current use (and consequently little user impact).
    Among the other sources of EPA's uncertainty of its estimate are 
the inherent variation in the size and level of agricultural activity 
across States, and the anticipated variation in State approaches, 
ground-water protection objectives and the like. EPA does not believe 
the margin of uncertainty in its estimate exceeds the magnitude of the 
estimates. Among the reasons for believing EPA's estimate 
underestimates the true impact of regulatory action are unanticipated 
difficulties or obstacles in State implementation of its requirements 
(such as unanticipated non-compliance, necessitating substantially more 
enforcement activities), as well as those considerations described 
above. In addition, EPA has not taken into account potential increased 
costs of Federal-State enforcement of sale/use prohibitions for those 
States that fail to develop Plans. For the reasons explained above in 
describing the assumptions, EPA does not anticipate many States will 
not develop approveable Plans for all five pesticides. For those few 
cases that may arise it is EPA's expectation that enforcement and 
compliance costs will be minimal, since part of the reason for State 
disinterest in developing SMPs for these pesticides will be their 
insignificant use in the State. Among the reasons for anticipating that 
EPA's estimate overstates the true level of State expenditures would be 
the deliberate conservatism in pricing aggregate State costs on the 
basis of a ``model'' Plan that represents substantial effort, limiting 
the estimate of economies-of-scale achieved by developing multiple SMPs 
and the possibilities for innovations in ground-water assessment and 
monitoring techniques (particularly the latter).
    Registrant (or pesticide-industry) impacts are those that would be 
the direct result of regulatory action, apart from any anticipated loss 
of income from reduced use of the products attributable to regulatory 
restriction. Attributable costs would include: (1) The lost revenue 
associated with decreased use of the products, caused by State risk-
management measures; (2) the costs of increased technical assistance 
(such as ground-water monitoring) and outreach to users that the 
registrants might provide, to help them ascertain and follow the new, 
applicable State management measures or other safeguards on the 
chemicals' continued use; and (3) the direct costs of relabeling and 
compliance with the administrative provisions of this proposed rule. 
The first category, lost revenue, was calculated as a function of 
likely State actions, which in turn are represented as three scenarios 
of differing regulatory stringency. Projected annual lost revenues for 
a ``medium impact'' scenario was calculated to be $33.6 million. Using 
current sales figures from the major registrants of these five 
pesticides, this figure represents an estimated 0.06 percent decrease 
in total sales, and a 0.48 percent decrease in pesticide-product sales 
for these registrants. The estimated costs in the second category are 
those that are incremental to ongoing ground-water monitoring, 
technical assistance or outreach efforts the registrants now perform 
with regards to ground-water protection. They are estimated to be in 
the range of $3.1 to 12.7 million annually, conceived as substantial 
new ground-water monitoring activities performed in addition to State 
efforts. These costs can also be attributed to the possible new ground-
water monitoring requirements that EPA may prescribe on registrants 
concurrently with State development of SMPs (see Unit III. of this 
preamble). While EPA has not committed to the development of such 
requirements at this time, the Agency nevertheless includes a cost 
estimate for the activity in the interests of not underestimating 
costs. Uncertainties include EPA's actual specification of those 
requirements, the level of effort represented by that specification, 
the identification of further technical-assistance activities and their 
delineation from ongoing regulatory efforts.
    By far the most substantial impact (in terms of relative magnitude) 
is anticipated to be impacts on agricultural

[[Page 33287]]

and non-agricultural users, and associated indirect impacts of reduced 
consumer benefits. These impacts pertain to the changes caused by 
regulatory restrictions in use of pesticides and the consequent changes 
in agricultural (and other economic) productivity and expenditures. In 
addition to being the largest component of cost, its magnitude is the 
most uncertain and difficult to estimate. Estimating these impacts 
entails an econometric analysis with consideration of a multitude of 
cascading secondary effects across geographic regions and economic 
sectors and with estimated impacts expressed through a variety of 
economic measures. These difficulties are compounded by the necessary 
consideration of the combined behavior changes of perhaps a million 
affected farmers and other users, the normal uncertainties in the 
agricultural sector (the effect of weather, etc.) and the like.
    EPA attempted to anticipate as many of these interactions and 
uncertainties as possible by using a widely used multi-sector, multi-
regional econometric computer simulation model called AGSIM. The 
analysis was performed to take into account not only regional 
variations in commodity supply and production (i.e., varying responses 
to changes in per-acre yields, variable costs, and prices) but also the 
present and projected influences of farm policy elements (e.g., Federal 
price-support and conservation programs, Federal monetary policy, etc). 
These measures aggregate into separate (and additive) dollar estimates 
of the combined impact to the agricultural-production sectors 
(expressed as the change in net agricultural production and income) and 
the consequent decrease in domestic-consumer benefits (sometimes 
referred to as ``surplus value,'' or the amount of additional consumer 
expenditures to maintain the same standard of living as reflected in 
the ``baseline'' conditions, prior to a regulatory action).
    In order to estimate impacts it is necessary to estimate certain 
effects of the SMPs and use these as inputs to the econometric model. 
Specifically, a critical task was to estimate how State risk-management 
measures would influence: (1) The acreage where these five pesticides 
are used; (2) yield impacts; and (3) input (i.e., pesticide-chemical) 
cost impacts. Thus, SMP impacts on users are estimated by a matrix of 
combinations of these three factors (taking the availability of non-SMP 
pesticide substitutes into account) and the consequent change in crop 
yield and price. The critical measure of impact is the reduced treated 
acreage associated with State risk-management measures. These values 
must be regarded as a proxy for the variety of potential effects that 
SMPs may have on agricultural practices. They are not intended to 
represent a forecast of actual State practices, but rather a surrogate 
measure of their potential effect on agricultural practices.
    These estimates were made by consultation with a variety of 
sources. Affected acreage was identified by the use of a Ground-water 
Vulnerability Index for Pesticides designed by Robert Kellogg of USDA's 
Soil Conservation Service. A percentage of these affected acres was 
assumed to be subject to either restricted or prohibited use under 
State Management Plans; this percentage varied according to impact 
scenario and was based upon the 1992 Wisconsin Atrazine Rule. EPA tried 
to account for the considerable uncertainty about the impact of State 
management measures by positing a variety of reduced-use scenarios 
across the principal use areas of these five pesticides. EPA believes 
the most-likely estimate of user impacts rests with its medium-impact 
scenario, but has provided companion low- and high-impact scenarios for 
comparison. The Regulatory Impact Analysis accompanying this proposal 
provides a fuller explanation of EPA's estimates and the methodology 
used to derive them. The SMP-use restrictions have the anticipated 
effect of lowering expected yields and pesticide input costs. 
Restrictions on application rates lower pesticide input costs since 
total usage declines; use prohibitions also lower costs since the cost 
of alternative pesticides are less than that of the SMP pesticides. 
Crop producers are actually expected to be better off in terms of net 
crop revenues as a result of such restrictions, due to the combination 
of increased prices obtained for affected commodities and reduced input 
costs. Increased commodity prices are predicted due to reduced acreage 
planted, which in turn, decreases the total supply of a particular 
commodity. However, increased prices resulting from reduced supply are 
a net negative impact to the economy overall, in the form of reduced 
consumer surplus value.
    At the same time, increased feed crop (corn, soybean, sorghum) 
prices raise input costs for livestock producers. Coupled with stagnant 
or declining demand for livestock products, increased input costs 
negatively impact livestock returns in this analysis by reducing 
livestock revenues. Because the reduction in livestock returns is 
estimated to be greater than the increase in crop returns, net impacts 
to the U.S. agricultural sector are negative, but relatively minor (-$1 
million to -$11 million, across the three scenarios).
    Correspondingly, indirect impacts, in the form of reduced consumer 
benefits, are estimated to be in the range of $242 to $254 million.
    While the absolute magnitude of such impacts appear to be 
substantial, in relative terms such impacts are moderate. Relative to 
the economic value of U.S. field corn production ($16 to $23 billion), 
such impacts are small. For example, the SMP-use restrictions are 
anticipated to lower U.S. field corn production by about 1 percent, 
leading to a potential 1.1 percent increase in market prices. Such 
impacts would have a de minimis effect on the Gross Domestic Product. 
Average annual consumer expenditures and food prices would change less 
than $1.00 per person (from $0.94 to $0.98) as a result of these 
impacts. Individual farmer income in the aggregate would also change 
little, but regional effects of greater magnitudes (both positive and 
negative) could occur.
    This range of projected impacts compares to impacts of $ 3.6 
billion or more in combined user costs and reduced consumer benefits, 
associated with either outright cancellation of the five pesticides 
(plus aldicarb, which had minimal costs associated with its management) 
or more stringent, nationwide use restrictions, as estimated by Taylor, 
et al. in 1991, using a similar econometric approach.
    EPA's method for estimating user impacts, like its projection of 
State-program costs, relies on some key simplifying assumptions: (1) A 
degree of regulatory restriction will translate into a discrete (and 
predictable) level of decreased (or alternative) pesticide use, 
resulting in predictable adverse effects to agricultural production and 
the other relevant economic effects summarized above; and (2) the 
scenarios vary (predictably) in the degree of regulatory restriction 
they represent, and this difference can be expressed in terms of the 
cropped acreage subject to reduced, substituted or eliminated pesticide 
use. Among the reasons for anticipating that EPA's estimate understates 
the true potential impact of ground-water protection measures are: (1) 
That the analysis pertains only to uses on field crops (which, however, 
represent over 90 percent of the combined current use of these five), 
overlooking the potential impact on fruit and vegetable crops; and (2) 
that EPA assumes all States will participate, so that no greater 
restrictions on use will ensue from the fact that State inaction causes 
a

[[Page 33288]]

complete curb on use. However, EPA has equal or greater reason to 
believe its estimate overstates the actual potential impact; chief 
among these is faith in the States' ability to develop a variety of 
innovative management measures that will minimize the disruption in 
crop production caused by ground-water safeguards. State 
resourcefulness in developing new approaches will undoubtedly outrun 
the Agency's present expectations. It is already clear, for instance, 
that States will emphasize measures that will enhance the 
sustainability of agricultural production simultaneously with ground-
water protection, preserving much of the necessary use of the 
pesticides in question. Also, inevitable improvements in ground-water 
monitoring and vulnerability-assessment techniques will enable states 
to ``fine-tune'' necessary restrictions to a degree EPA cannot yet 
anticipate in its estimate. In addition, in developing its estimates of 
crop yield losses, EPA did not take into account the considerable 
promise that is subsequently emerging in the areas of integrated pest 
management and other reduced-use strategies.
    In summary, it needs to be stated that in distinguishing the 
various costs that may be attributable to Federal regulatory action for 
purposes of weighing the costs and benefits of any action, EPA did not 
attempt to assess the reasonable likelihood that a particular category 
of parties would actually incur the costs. For example, the boundaries 
between ``State'' and ``registrant'' costs may be considerably more 
blurred than our analysis would suggest. A variety of activities 
attributed to the States in managing the use of a pesticide subject to 
an SMP rule (including those involving substantial levels of effort, 
such as ground-water monitoring or user education and outreach), for 
example, could in practice be either performed (in part or in whole) or 
paid for (either directly or through State imposition of fees) by the 
registrants. Likewise, some of the activities identified by EPA as 
``registrant costs,'' e.g., the provision of increased user training 
and technical assistance, could be expected to be performed often at 
the behest of State agencies pursuant to their Plans. Accrual of 
expenditures accurately to the various parties was of less importance 
to EPA in making this analysis than was concern for the projection of 
overall level of effort and expenditure attributable to this rule.
    2. Benefits. Chapter 7 of the RIA contains the Agency's appraisal 
of the potential benefits associated with establishing SMPs for these 
five pesticides. This appraisal begins by cataloging the different 
kinds of values associated with protecting ground water as a natural 
resource. These values are categorized in terms of their various 
services as a resource. This categorization follows a recent Agency 
conceptual framework for assessing the economic value of ground-water 
protection in evaluating regulatory impacts (Ref. 19). Each of these 
service values, (associated with two general functions of ground water: 
both as a source of water stock and as a discharge to surface water 
supplies) may be subject to a variety of economic valuation techniques. 
FR Doc. 96-16173 Pesticides and Ground Water State Management Plan Regulation
Since these categories generally involve the value of the resource in 
terms of its economic use, other categories of value recognized by 
natural-resources economists must also be acknowledged: the so-called 
altruistic, bequest, and existence values (sometimes referred 
collectively as ``non-use value'') associated with protecting a natural 
resource per se.
    In general, however, the benefits of SMPs will accrue from the 
reduced levels of ground-water contamination, by substances associated 
with adverse human and/or environmental effects, that result from the 
regulatory safeguards required by the individual Plans. It is the 
presence of this contamination that jeopardizes any and all of the use 
and non-use values under consideration.
    In order to perform a reasonable quantitative analysis of benefits, 
accurate and reliable estimation of exposure levels (both existing and 
projected, and in the case of the latter, projected for a number of 
different regulatory options) are critical. Unfortunately, reliable 
estimation of ground-water contamination occurrence is among the most 
difficult and uncertain issues with regards to ground-water concerns. 
Past and current efforts at ground-water monitoring have not been of a 
sufficient level and frequency to give adequate assurance that the 
Agency knows the levels of occurrence of pesticide contamination of 
ground water, either of the specific pesticides addressed in this 
proposed rule or of pesticides in general.
    The United States Department of Interior, in comments submitted to 
EPA regarding the proposed Ground Water Restricted Use Rule (in 56 FR 
22076, referred to in Unit I. of this preamble), characterized the 
state of knowledge associated with the nation's ground-water monitoring 
efforts as follows: ``Given shortcomings in national ground-water 
monitoring efforts, it is highly unlikely that all locations of all 
contaminants in ground water have been determined.'' [July 5, 1991 
letter from Jonathan P. Deason, Director, Office of Environmental 
Affairs; exhibit 7 in OPP comment file no. 36172]. While not 
necessarily reflecting the views of EPA, these comments are testimony 
to the limitations associated with the evidence of contamination from 
current ground-water monitoring results, particularly the substantial 
likelihood of under-estimating the present and future level of 
exposure. Other methods of estimating prospective occurrence, such as 
projections from data on the leaching potential, volume and location of 
use of a pesticide or projections using environmental-fate-and-
transport models, have even greater limitations (see, for example, 
National Resource Council, ``Ground Water Vulnerability Assessment,'' 
NAS Press, 1993, for a fuller description of the strengths and 
weaknesses of various ground-water analytic techniques).
    The consequences of this potential under-measurement of present 
ground-water contamination has another dimension. Since known ground-
water contamination is particularly localized, it is characterized by 
the incidence of limited ``hot spots'' of high concentrations. 
Occurrence of ground-water contamination is unevenly distributed, due 
to the variety of hydrologic and topographic factors. Locations of high 
concentrations of pesticides (and a corresponding high risk of 
potential adverse effects) in ground water are dispersed unevenly 
across the country. The overall profile of the risks associated with 
pesticides in ground water, then is one of large numbers of people at 
relatively low risk, punctuated with ``hot spots'' of higher risk. The 
risk concentrated in these ``hot spots'' are likely to exceed national 
average risks, but are difficult to characterize using aggregate 
occurrence estimates. This unevenness in the distribution of risk 
levels raises concerns regarding ``environmental equity,'' to the 
extent that effects are disproportionately high and adverse, which the 
Agency is committed to take into account as a matter of policy.
    Finally, it should be noted that taking the next step of 
quantifying human health risk by combining population exposure figures 
with some benchmark of toxicity associated with a unit quantity of 
exposure, is hampered by limited methodologies for quantifying hazard. 
At present, the Agency customarily confines hazard quantification to 
carcinogenicity (e.g., projecting ``number of cancer cases avoided''), 
while the possible consequences of other toxicological endpoints cannot 
usually be presented with the same appearance of precision.

[[Page 33289]]

    Despite the limitations on available evidence and methodologies 
discussed above, as a matter of illustration the Agency has presented 
in the RIA a number of different estimates of nationwide human exposure 
to these five pesticides in drinking water using ground-water sources. 
These alternatives represent different data sources and estimation 
methods. Three of these data sources have been referenced earlier in 
Unit IV. of this preamble: the Pesticides in Ground Water Data Base, 
the National Pesticide Survey and the National Alachlor Water Well 
Survey. Another estimate is based on the application of a modeling 
procedure, i.e., the application of an environmental-fate model using 
assumed values for prevailing hydrogeological conditions across all 
local areas where corn pesticides are used. This estimate is provided 
in a yet-unpublished Agency analysis of the cumulative risks and 
benefits of a host of pesticides frequently used on corn, a so-called 
``corn cluster'' analysis. A copy of this analysis is available in the 
public docket for this rule-making.
    The Agency presents these alternative estimates without making a 
judgement that one estimate is superior to another, or that any (or 
all, considered collectively) can be considered a reliable estimate of 
nationwide exposure and hence, national risk. Three of the four 
analyses provide estimates of both: (1) the number of individuals 
exposed to any measurable concentration of these five pesticides (or, 
in the case of the NPS, a surrogate estimate of ``total pesticide'' 
exposure); and (2) the number of individuals exposed to concentrations 
at or above health-based ground water reference points. The model-based 
estimate also estimates total population with any exposure, but offers 
a calculation of baseline cancer and non-cancer risk in place of the 
number of individuals exposed above reference points.
    It is notable that when viewed together, there is a wide variation 
in central-tendency estimates of population exposed among the studies, 
as well as considerable uncertainty surrounding each estimate, taken 
individually and together. For example, best estimates derived from the 
available statistically-based studies of total population exposed to 
any concentration of the five pesticides, from domestic wells alone, 
range from a few hundred thousand to as many as 5 million. Estimates 
from the non-statistically based Pesticides in Ground Water Data Base, 
which does not differentiate private and public well occurrence, range 
to more than 20 million. More importantly, the estimated numbers 
exposed to high concentrations range from nearly none to one-half 
million people or more; taking estimates of random error into account, 
the number exposed above health-based standards could theoretically 
also be as high as 20 million. Estimates from the Data Base for this 
subset run as high as 2.84 million people.
    In addition, each of the four estimations discussed has specific 
shortcomings which need to be recognized before relying on any 
estimate, considered either individually or together, as a credible 
basis for estimating the benefits of the rule. Some of the problems to 
be aware of with these studies are: (1) Most fail to account for the 
entire nationwide exposure potential, leaving out parts of the total 
exposed population (e.g., those drinking from community water systems); 
(2) not every data source addresses precisely the five pesticides in 
question; (3) most are based on limited and imperfect monitoring data 
(i.e., data from surveys with design flaws, or data that are not 
statistically based), and the modeling exercise is not based on 
monitoring results at all; (4) all of them measure or estimate the 
frequency and concentration of well contamination and not human 
exposure per se, which means that certain unverified assumptions were 
made regarding the numbers of people drinking well water to produce 
population-exposure estimates; and (5) they all produce estimates that 
are highly uncertain, for example, with the potential for random error 
(among the statistically designed studies) represented by 95 percent 
confidence intervals ranging from zero to the hundreds of thousands. 
One method (based on the PGWDB) is based on a larger amount of well 
water sampling, but such sampling is not statistically based, so no 
estimate of the degree of expected random error in the estimate is 
possible.
    Given the wide range of divergent estimates, and the significant 
limitations on their reliability, the Agency cannot reasonably identify 
a single ``best estimate'' of prevailing exposure to the SMP pesticides 
in ground water. The Agency believes that the evidence of substantial 
contamination of ground-water-based drinking water supplies, indicated 
by the data summarized in Unit IV. of this preamble, provides reason to 
believe: (1) That many individuals (running up to the thousands, or 
even hundreds of thousands) are or will be consuming ground water 
contaminated by one or more of these pesticides at levels above health-
based standards, in the absence of effective, localized risk-reduction 
measures as envisioned in SMPs; and (2) that many more individuals 
(running into the millions) are or will be consuming ground water with 
at least detectable levels of contamination. While concern tends to 
focus on the former subset, SMPs can be expected to substantially 
reduce the exposure to the larger population as well. The Agency 
further believes that the potential health risk represented by this 
magnitude of occurrence/exposure bears a reasonable relation to the 
magnitude of the economic impacts discussed in the section above.
    The uncertainty surrounding the actual levels of individual 
exposure makes it very difficult to take the next step, that is, 
combining indications of toxicological potency with the estimates of 
exposure to obtain an estimate of human health risk. Where the 
particular study cited presents no estimates of population risk 
associated with the estimated exposure, the Agency has not developed 
any subsequent estimates. However, one of the studies (the modeling-
based analysis associated with the Corn Cluster) offers both estimates 
of cancer and non-cancer population risks. The analysis suggests that 
these five pesticides together represent about 0.4 excess cancer cases 
per year, given a 3-meter depth of ground water as a drinking water 
source. The preponderance of this risk comes from one chemical alone, 
atrazine. The analysis arrives at an estimate of maximum individual 
cancer risk at this depth of 2  x  10-4. To put the magnitude of 
this risk into perspective, as a measure of risk in hotspots, is to 
note that it is roughly twice as great as the incremental lifetime risk 
that this analysis estimates for the dietary pathway, about 8  x  
10-5 for an individual of average exposure. A less conservative 
assumption that a 1 meter depth is representative of ground water 
recharge leads to an estimate of about 5 statistical cancers a year, 
with a corresponding estimate of maximum individual cancer risk of 3 
x  10-3, or nearly 40 times the average dietary estimate stated 
earlier. However, given that neither estimate can be regarded as a 
direct representation of ground-water exposure (since the model only 
simulates the loading to ground water via percolation through crop root 
zones), the Agency regards neither estimate as authoritative. In 
particular, the Agency has reason to believe the 3 meter estimate 
understates ground-water occurrence, based on the Agency's

[[Page 33290]]

experience with controlled field-scale studies, and describes this 
experience in Chapter 7 of the RIA. In addition, it is very likely that 
the cluster analysis underestimates the risk posed by pesticides other 
than atrazine. Specifically, risks presented by alachlor and simazine 
should be only slightly less than that of atrazine, based on the 
monitoring record.
    The Agency is not attempting to authoritatively quantify the risks 
of ground-water contamination by these five pesticides, nor to monetize 
the value of avoiding these risks. The Agency believes such estimates 
are difficult to support scientifically, under these circumstances. The 
Agency solicits comment on the reliability of risk estimates that may 
be developed from these exposure estimates cited above, or from other 
sources.
    Beyond the difficulties of characterizing the magnitude of 
potential human exposure to these pesticides in drinking water, absent 
the risk reduction afforded by SMPs, there remains the question of how 
effective SMPs will be in reducing that risk. The main impediment to 
the evaluation of SMPs' prospective effectiveness is the fact that 
individual SMP provisions remain to be set. However, even making some 
assumptions as to the general features of future SMPs, there remains 
the problem of estimating ground-water contamination occurrences. As 
mentioned earlier, present levels of ground-water monitoring are 
inadequate to gauge the levels of overall ground-water contamination 
with confidence. Alternatives to monitoring, e.g., environmental fate 
models, are not yet developed to provide an adequate substitute to 
monitoring results.
    However, what little evidence is available to the Agency appears to 
support the conclusion that the risk-management measures contained in 
SMPs are likely to be effective in reducing the occurrence of ground-
water contamination. The most reasonable approach to assessing the 
prospective effectiveness of SMPs is to consider the closest existing 
analogue to SMPs, i.e., the performance of existing State-imposed 
localized risk-reduction measures. Very few such analogues presently 
exist, but there is recent information that the Wisconsin atrazine use 
restrictions referred to earlier have resulted in an overall reduction 
in atrazine concentrations in contaminated wells.
    In 1995, the Wisconsin Department of Agriculture, Trade and 
Consumer Protection (DATCP) conducted an extensive analysis of atrazine 
and its metabolites in drinking water wells located within risk-
management areas imposed by the Department beginning in 1992, which had 
been previously monitored (Ref. 22). Seventy-six (84 percent) of 90 
wells sampled in 1995 declined in total atrazine concentration, and 16 
percent increased. For the 76 wells that decreased in concentration, 
levels decreased an average of 2.5 parts per billion (ppb). While the 
re-sampling of these wells generally occurred in one time period, from 
June to September 1995, the study compares these results to a baseline 
sampling frame that varies for each well. Each well was sampled with 
varying frequency across a period that spans from March 1990 to 
September 1994. Relative to the State standard, 57 percent of a 
slightly larger universe of 111 wells (encompassing the 90 cited above) 
are now below 3 ppb (with an average concentration of 1.4 ppb). The 43 
percent of wells still above the 3 ppb standard had an average 
concentration of 5.9 ppb. The overall average concentration for the 111 
wells is 3.3 ppb. While the report attributes the reductions in 
contamination to the use reductions, it was less able to explain the 
reasons for the occasional increases. However, the report mentions 
several plausible reasons, including the possibility that these wells 
are deeper (and so experienced higher levels of contamination from pre-
controlled atrazine use later than the norm), or are located in more 
recently designated areas, or were affected by continued illegal use or 
spills near the wells. These are in addition to the common-sense 
explanations, i.e., the natural variability in sample results over time 
and/or metabolite contributions from non-prohibited triazine use in the 
areas (because atrazine, simazine, and cyanazine have some common 
degradation by-products that will be detected by first-round analytic 
methods). These data provide some evidence that state risk-reduction 
measures seem to have a beneficial effect, reducing both the number of 
occurrences of pesticide contamination in affected areas and the level 
of that contamination.
    In addition to health effects, the Agency believes that the 
possibility of resource effects need to be acknowledged and considered 
in the decision whether to exact further regulatory protection for 
these pesticides. There are two major considerations. First is the 
adverse effect to ecosystems linked to ground-water sources. The 
scientific basis for estimating such things as the location, frequency, 
and duration of sensitive-ecosystem exposure to such ground-water 
contamination is less developed than even the limited information 
discussed above for human exposure. At the same time, the risk of 
ecological adverse effects is certainly a real possibility, and should 
not be discounted merely out of lack of currently available scientific 
means of ascertaining it. Second, there is an even more inestimable, 
but nonetheless relevant, concern over the intrinsic or future value of 
ground water as a resource, as free of man-made pollution as may be 
practicable. Studies that estimate ``willingness to pay'' based on 
survey methodologies have suggested proxy values of substantial 
magnitude, which if extrapolated to national scale, amount to billions 
of dollars, but the estimates from this controversial approach have 
uncertain applicability. One can hypothesize a threshold willingness to 
pay commensurate to the estimated costs of this proposed rule, which 
would compare favorably to the results of previous studies. 
Specifically, if an estimated 5 to 8 million potentially-affected 
households (an estimated 15 to 20 million potentially exposed 
individuals divided by the national-average per household population of 
2.64) were willing to spend between $47 to $63 annually, these sums 
would be commensurate with the $356 million projected cost of the SMP 
rule. EPA believes that these estimates are well within the range of 
expectations, but only a carefully conducted survey, expressly 
clarifying the expected risk-reductions specifically associated with 
SMPs, could confirm these expectations. Likewise, prevention is a value 
that EPA subscribes to because the costs of prevention can be expected 
to be much lower than the costs of remediating contaminated ground 
water when and if it occurs.
    The fact that the dimensions of risk and the effect of risk-
reduction efforts are both highly uncertain dictates a policy to 
proceed cautiously and with maximum flexibility. The Agency believes 
the prudent course in the face of the uncertainties presented by 
pesticidal ground-water contamination is to take positive action that 
avoids irrevocable national policy courses at the outset that might 
lead to programmatic dead-ends. The Agency believes this is the essence 
of the SMP approach, and that this is the most practical policy course 
from among the regulatory alternatives.
    EPA therefore recognizes the lack of information necessary to 
calculate quantifiable benefits that may be associated with the SMP 
approach. However, the States, in electing to participate, will have 
made a practical

[[Page 33291]]

evaluation of both the real and intangible benefits of ground-water 
protection measures, and their participation will represent the choice 
for prevention over remediation. These States will have evaluated the 
benefits of participating relative to their respective environmental 
policy philosophy and goals and on the State economies depending upon 
pesticide use.

D. Risk-Benefit Conclusions

    Based on the information currently available, it is EPA's reasoned 
determination that the benefits of preventing ground-water 
contamination by these five pesticides justify the expected costs of 
implementing preventive measures through the SMP approach, and further, 
that the SMP approach appears to be the most cost-effective of the 
means available for protecting ground water.
    EPA believes that the level and nature of protection to be afforded 
by SMPs is appropriate to the magnitude and character of contamination 
potential indicated by the evidence. In developing the SMP approach in 
cooperation with a broad spectrum of interested parties from the public 
and private sectors, there was much discussion of the alternative 
approach of having EPA impose national-level risk-reduction measures, 
such as labeling or use restricted to certified applicators. That 
alternative is discussed in Unit III. of this preamble and is being 
offered for comment in this proposal. The Agency wishes to point out, 
however, several factors which led EPA to propose the SMP approach 
rather than the national-level restrictions approach.
    The main issue is whether label changes alone, or in combination 
with restricted use classification, and perhaps additional requirements 
placed on the registrants would be sufficient to address the risks of 
ground-water contamination. The evidence of each of the five 
pesticides' ground-water contamination risks suggests no particular, 
specific circumstances causing such contamination. The evidence of 
present ground-water contamination is so broad and general that it is 
unlikely that a pesticide user could readily identify a specific 
condition that would, to a high degree of certainty, cause the 
pesticide to contaminate ground water. Consequently, it seems 
questionable whether clear and simple label instructions could be 
developed that would adequately identify conditions for a user to avoid 
such that ground water risks would be significantly reduced or 
eliminated. Many ground water experts, including EPA staff, believe 
that reliable neutralization of the risks requires a knowledge of 
technical, site-specific factors that most pesticide users cannot 
reasonably be expected to possess. Furthermore, as a matter of policy, 
EPA believes that the users of pesticide products should not be given 
the burden of interpreting label instructions that are either 
unreasonably complex or technical, or are uncertain to achieve their 
purpose. The training associated with classification for restricted use 
may alleviate some of this concern, but would not address the issue of 
whether label restrictions would actually work.
    If this alternative approach were to include monitoring 
requirements to demonstrate effectiveness, and use prohibitions if 
specific detection triggers were met, then this approach might well end 
up being substantially more onerous to both users and registrants than 
SMPs. The Agency is requesting detailed comments on this alternative 
from all potentially affected parties.
    In considering the issue of national-level labeling measures, EPA 
has taken into consideration the fact that new risk-reduction measures 
have recently been in effect for atrazine (since 1992) which are 
intended to reduce the pesticide's contamination potential for both 
surface and ground water. These measures include label changes 
providing for the deletion of certain non-crop uses including highway 
and railroad rights-of-way, reduction of the rates of application for 
remaining crop uses and the imposition of set-backs (non-application 
zones) for wells and bodies of water, prohibiting use and mixing/
loading within specified distances from surface waters and drinking 
water wells. These measures have not been in place long enough for EPA 
to discern any positive effect on the ground-water contamination 
potential of this pesticide. However, when EPA agreed to these risk-
reduction proposals (which were voluntary measures proposed by the 
registrant), it made clear that additional measures would have to be 
considered. Furthermore, the Agency is taking into account the 
voluntary phase-out and eventual cancellation of cyanazine, announced 
in August 1995 (see 1., below). Finally, EPA is anticipating that all 
the pesticides ultimately subject to SMPs will also be classified for 
``conventional'' restricted use, that is, restricted to use by or under 
the direct supervision of a certified applicator.
    In the Strategy EPA committed to considering existing State and 
local measures in making its regulatory decisions about pesticides with 
ground-water concerns. To EPA's knowledge, a total of 10 States have or 
are working on some kind of independent restriction for one or more 
pesticides with ground-water concerns. However, not all of these apply 
to the five pesticides discussed here. Another 12 States have some 
authority to impose such restrictions, but have heretofore not employed 
it. From a national perspective, this level of effort appears to be 
inadequate to address the extent and character of ground-water 
contamination potential associated with these five pesticides. It 
appears that, in the main, States are anticipating that this proposed 
rule requiring pesticide-specific SMPs will serve as the framework for 
their own efforts in this regard.
    Finally, it is EPA's belief and expectation that SMPs should 
sufficiently reduce the risks associated with the ground-water 
contamination potential of these five pesticides, so that full 
cancellation of use based on ground-water concerns alone is not likely 
to be necessary. While the potential risks represented by these five 
are substantial and warrant the imposition of effective preventive 
measures, the measures to be taken by the States should be adequate to 
mitigate the risks.
    A remaining issue is whether the risks associated with ground water 
may combine with other routes of exposure for any of these five 
pesticides to constitute an unreasonable risk and thus warrant 
cancellation. EPA customarily uses the Special Review procedure to 
determine whether the combination of different routes of exposures 
represents unreasonable risks. Alachlor and cyanazine have been subject 
to Special Reviews in the past, and the three triazine active 
ingredients (atrazine, simazine, and cyanazine) have just recently 
begun Special Review. Any or all of these five may be subject to this 
further consideration in the future. In such Special Reviews, EPA will 
take into account the level of risk-reduction expected to be afforded 
by SMPs in making an evaluation of the pesticides' overall risk to 
human health and the environment.
    1. Cyanazine special review. The recent agreement between the 
Agency and DuPont Agricultural Products, the principal registrant of 
cyanazine in the United States, to phase out and eventually terminate 
sale and use of cyanazine, affects this proposed rule. On August 4, 
1995, DuPont signed an agreement with EPA whereby DuPont will amend its 
registration to: (1) Reduce the maximum use rates on cyanazine labels 
in four increments,

[[Page 33292]]

from 1997 to 1999; (2) cease production and sale at the end of 1999; 
and (3) prohibit all uses of cyanazine by the end of the year 2002. 
This arrangement will resolve the Agency's concerns with respect to 
cyanazine in its Special Review of the three triazines. EPA will soon 
publish its termination of the cyanazine Special Review. However, EPA 
will proceed with proposing cyanazine to be subject to SMPs in this 
rule, for several reasons. First, until the Special Review is 
officially terminated and the registrant's voluntary actions go into 
effect, the ground-water risks enumerated in this notice will remain, 
warranting at least proposed regulatory action. Second, even when the 
agreement is implemented, the phase-out schedule provides for a brief 
interval during which cyanazine may be used in States that would need 
SMPs. Third, the Agency is concerned with the possibility that 
cyanazine could be registered at some future date as a completely new 
pesticide. In that event, it is the Agency's judgement at this time 
that the present evidence of the pesticide's severe contamination 
potential requires that any such future use needs to be subject to 
SMPs.
    It may be EPA's judgement in considering a final SMP rule that 
cyanazine's eventual cancellation will be sufficient to address the 
Agency's ground-water concerns; if so, it may choose to issue a final 
rule for only four of the pesticides proposed today. In any event, the 
Agency wishes to emphasize that the fact that cyanazine use will 
terminate soon after the effective date of the SMP restriction will be 
taken into account when EPA evaluates State submissions. EPA does not 
anticipate that State Plans for cyanazine will have to be as extensive 
or detailed as for pesticides whose uses are expected to continue 
indefinitely.
    2. Alachlor Special Review. In 1985, EPA initiated a Special Review 
of Alachlor (50 FR 1115, January 9, 1985). As noted above, alachlor was 
classified as a B2 (probable human) carcinogen, and the 
carcinogenicity potential has been quantified, although the 
classification is now under review. EPA concluded the Special Review of 
alachlor (52 FR 49480, December 31, 1987), after taking the following 
actions to reduce risk for workers: EPA classified alachlor for 
restricted use by certified applicators; prohibited aerial application 
using human flaggers; and required persons applying alachlor to 300 or 
more acres per year to use mechanical transfer systems for mixing and 
loading alachlor. In addition to these regulatory actions, however, EPA 
deferred action on whether the risks posed from alachlor in drinking 
water from contamination of ground water required regulatory action. 
EPA concluded that the further evaluation of the ground-water risks 
would offer an appropriate occasion to revisit the overall risks and 
benefits of alachlor (including dietary risks) on a crop-by-crop basis 
to determine whether the risk benefit balance had changed to a degree 
requiring regulatory action.
    Since 1987, Monsanto has submitted the National Alachlor Well Water 
Survey (NAWWS) and review has been completed. EPA's concerns with 
respect to continuing ground-water risks are evident in its proposal to 
classify alachlor for SMPs in this proposed rule. In addition, EPA has 
reviewed recent trends in usage and percent of crop treated with 
alachlor and determined it is not necessary to revisit the risk/benefit 
determination of alachlor on a crop-by-crop basis. The dietary risks 
posed by alachlor were in the 10-6 range at the time the Special 
Review was concluded and have declined further since then.
    EPA has determined that the remaining Special Review concern about 
alachlor in ground-water is adequately addressed by the actions 
proposed in today's document. Thus, EPA concludes that the concerns 
deferred by the Special Review will have been addressed with 
promulgation of this proposed rule and no further action related to the 
Special Review of alachlor will be necessary upon this proposed rule's 
promulgation. In a separate notice, EPA will announce the cessation of 
the alachlor special review.

E . Analysis of Regulatory Options

    In developing the Strategy EPA evaluated a range of available 
regulatory options in addition to the SMP approach. Specifically, EPA 
compared three general approaches in a companion document to the 
Strategy, the ``Pesticides and Ground-Water Strategy: A Survey of 
Potential Benefits'' (Ref. 13). In supporting the comparative 
advantages of the SMP approach, this document compared it to the option 
of a projected extension of current national-level risk-reduction 
measures, and another of full cancellation of a problem pesticide. Both 
options were regarded as establishing the extremes of potentially 
effective and reasonably feasible alternatives to the SMP approach.
    The first alternative to SMPs was construed to permit significant 
levels of ground-water contamination before milder forms of regulatory 
action (e.g., label changes or restricted use) would be considered. In 
other words, the option constituted a non-prevention-oriented approach 
that, although contrary to Agency policy, constituted a conceivable 
approach to the problem of pesticide contamination of ground water. The 
option relied to a considerable degree upon remediation of projected 
contamination sites to address the problem; as such, it was tantamount 
to addressing the problem of pesticides in ground water through other 
environmental statutes, especially the Safe Drinking Water and 
Superfund (CERCLA) Acts. Consequently, the costs of remediation, and, 
by extension, the costs associated with degradation of ground water as 
a natural resource, were construed to be a larger component of this 
option's cost impacts than any other. While these impacts were not 
directly monetized in EPA's 1991 analysis (for the same considerations 
discussed in Unit IV.C. of this preamble), by indirect analysis EPA 
concluded that the ``status quo'' option would bear considerably higher 
societal-cost impacts than the SMP approach. Moreover, such an approach 
would be unacceptable on policy grounds, representing insufficient 
commitment to a preventive approach. This policy preference, of course, 
in part reflects EPA's discomfort about the ability to correct (much 
less correctly estimate the price of) ground-water contamination once 
it occurs. EPA's view is that such ground-water contamination may be in 
many circumstances practically irreversible, based in part on the 
economics of remedial action (where millions of dollars can be spent 
for uncertain results at a single site).
    Likewise, outright cancellation of one or more pesticides that 
might represent a substantial risk via ground water stands to entail 
far higher societal costs than other regulatory alternatives, such as 
SMPs. As the Taylor analysis (Ref. 5) indicates, the magnitude of user 
and consumer impacts associated with cancellation of these five 
pesticides dwarf those that might be associated with SMPs. Taking into 
account the additional administrative and technical program costs 
associated with the SMP approach (that would not be necessary if the 
pesticides were canceled instead), the SMP approach still appears to 
represent the most cost-effective approach. While absolute cancellation 
may provide a degree of greater surety that ground-water contamination 
will be averted (and in that way affords greater benefits), it is 
unlikely that the incremental gain in surety justifies the enormous 
difference in economic impact between the two options.

F. Request for Comments

    EPA is interested in receiving comments on its determination of the 
risks and benefits associated with its proposal to classify these five 
pesticides as subject to SMPs. EPA in particular invites all interested 
persons to submit further information concerning the risks and benefits 
(with respect to ground-water contamination, its prevention and any 
ancillary issues) associated with the use of atrazine, simazine, 
cyanazine, alachlor, and metolachlor, as discussed in this proposed 
rule. EPA would like comments on its estimate of the economic impacts 
of the proposed rule. For instance, has the Agency sufficiently 
addressed the indirect costs, such as those associated with minor use 
sites (e.g., fruits, nuts, and turf)? Of particular interest would be 
suggestions for how to improve both: (1) The estimate of present/future 
risks posed by these five pesticides in ground water absent further 
risk-reduction measures like SMPs; and (2) the estimate of 
environmental results likely to be achieved by SMPs.

VI. Notification to Secretary of Agriculture and the Scientific 
Advisory Panel

    As provided in 40 CFR 153.31(b), EPA has transmitted copies of this 
Notice and the Regulatory Impact Analysis, to the Secretary of 
Agriculture and the Scientific Advisory Panel for comment, prior to 
today's publication. In the process of reviewing the proposed 
regulation USDA has raised a number of concerns that the Agency has 
addressed in the text of the proposal. Among those concerns are the 
effects on minor uses, the potential for de facto cancellations with 
the States' failure to have an approved Plan, possible costs incurred 
by USDA programs, the need for an appropriate balancing of risks and 
benefits in the development and approval of SMPs, and the most 
appropriate statutory authority for taking regulatory action. USDA 
looks forward to a full public consideration of these and other 
critical issues in the promulgation of the final regulation. In 
particular, USDA urges the Agency to adopt a streamlined process which 
examines a broad range of possible alternatives for efficiently 
mitigating the environmental impacts while preserving sound 
agricultural production. The Panel had no written comments.

VIII. Regulatory Assessment Requirements

A. Executive Order 12866

    Pursuant to Executive Order 12866 (58 FR 51735, October 4, 1993), 
it has been determined that this is a ``significant regulatory action'' 
because it may result in an annual effect of $100 million or more. This 
action was therefore submitted to the Office of Management and Budget 
(OMB) for review, and any comments or changes made during that review 
have been documented in the public record.

[[Page 33294]]

    In addition, the Agency has conducted an economic analysis of the 
potential impacts associated with this proposed action, which is 
included in a Regulatory Impact Analysis' document prepared for this 
regulation. A copy of this analysis, which is discussed in Unit IV. of 
this preamble, is also included in the public record.

B. Regulatory Flexibility Act

    Pursuant to the Regulatory Flexibility Act (5 U.S.C. 601 et seq.), 
EPA has determined that this regulatory action does not impose any 
adverse economic impacts on small entities.
    An analysis of the prospective impacts of this proposed rule on 
small States, pesticide distributors, and agricultural producers was 
prepared as part of the Agency's economic analysis for this proposed 
action, which is summarized in Unit IV. of this preamble. This analysis 
is included in a Regulatory Impact Analysis' document, a copy of which 
is included in the public record for this action. This information is 
also being forwarded to the Chief Counsel for Advocacy of the Small 
Business Administration. Any comments regarding the economic impacts 
that this proposed regulatory action may impose on small entities 
should be submitted to the Agency at the address listed above.

C. Paperwork Reduction Act

    The information collection requirements in this proposed rule have 
been submitted for approval to the Office of Management and Budget 
(OMB) under the Paperwork Reduction Act (PRA), 44 U.S.C. 3501 et seq. 
An Information Collection Request (ICR) document has been prepared by 
EPA (EPA ICR No. 1771.01) and a copy may be obtained from Sandy Farmer, 
OPPE Regulatory Information Division; U.S. Environmental Protection 
Agency (2136); 401 M St., SW.; Washington, DC 20460, by calling (202) 
260-2740, or by sending an e-mail request to: 
[email protected].
    For PRA purposes, ``burden'' means the total time, effort, or 
financial resources expended by persons to generate, maintain, retain, 
or disclose or provide information to or for a Federal agency. This 
includes the time needed to review instructions; develop, acquire, 
install, and utilize technology and systems for the purposes of 
collecting, validating, and verifying information, processing and 
maintaining information, and disclosing and providing information; 
adjust the existing ways to comply with any previously applicable 
instructions and requirements; train personnel to be able to respond to 
a collection of information; search data sources; complete and review 
the collection of information; and transmit or otherwise disclose the 
information.
    Development and implementation of pesticide SMPs entails the 
collection of various sorts of information. In particular, States will 
need to create and/or gather information to conduct ground water 
vulnerability assessments, including data on agronomic practices (e.g., 
pesticide use, cropping patterns) and aquifer sensitivity; the States 
will either gather the data themselves or require third parties (users 
and/or pesticide registrants) to report the data. States will then use 
this data to assess the vulnerability of ground water to the pesticides 
requiring Pesticide SMPs. In addition, States may need to develop and/
or maintain ground-water monitoring efforts, or expand their existing 
efforts to gather chemical, physical, geological, biological, and other 
environmental data. This data will be necessary to support Pesticide 
SMP activities such as determining ground water levels, analyzing the 
existence and extent of contamination, and evaluating the effectiveness 
of management measures. Furthermore, once Pesticide SMPs are approved 
by EPA, States will need to submit an SMP Biennial Report every 2 years 
beginning 2 years from the EPA approval date and continuing every 2 
years thereafter. The SMP Biennial Report will provide a basis for 
measuring States' progress toward protection of ground water resources 
from pesticide contamination. The commitment to develop and report such 
information is a mandatory component of SMPs.
    The total annual burden for the information collection related 
activities associated with this proposed action is estimated to average 
412,560 hours per year for all respondents, including State (and 
territorial) government, and private parties. The per respondent burden 
(i.e., burden for each State, territory, or private party divided by 
the number of States, territories and tribal authorities expected to 
submit SMPs) is expected to average 7,367 hours per year. First year 
burden is estimated to be a total of 673,083 hours, with 12,1019 hours 
per respondent. The total annual costs for the information collection 
related activities associated with this proposed action is estimated to 
average $18,043,080 per year for all respondents, with an annual 
estimated cost of $322,198 per year for each respondent. First year 
start-up costs are expected to be $22,395,865, with an estimated 
$399,926 cost per respondent.
    An Agency may not conduct or sponsor, and a person is not required 
to respond to a collection of information unless it displays a 
currently valid OMB control number. The OMB control numbers for EPA's 
regulations are listed in 40 CFR part 9 and 48 CFR chapter 15.
    Comments are requested on the Agency's need for this information, 
the accuracy of the provided burden estimates, and any suggested 
methods for minimizing respondent burden, including through the use of 
automated collection techniques. Send comments on the ICR to the 
Director, OPPE Regulatory Information Division, U.S. Environmental 
Protection Agency (2136), 401 M St., SW., Washington, DC 20460, and to 
the Office of Information and Regulatory Affairs, Office of Management 
and Budget, 725 17th St., NW., Washington, DC 20503, marked 
``Attention: Desk Officer for EPA.'' Include the ICR number in any 
correspondence. Comments related to these estimates may be submitted to 
the address listed in the ADDRESSES unit anytime during the comment 
period for the proposed action. However, since OMB is required to make 
a decision concerning the proposed collection between 30 and 60 days 
after June 26, 1996, a comment to OMB is best assured of having its 
full effect if OMB receives it by July 26, 1996. The final rule will 
respond to any OMB or public comments on the information collection 
requirements contained in this proposal.

D. Unfunded Mandates Reform Act and Executive Order 12875

    Pursuant to Title II of the Unfunded Mandates Reform Act (UMRA) of 
1995 (Pub. L. 104-4), EPA has determined that this regulatory action 
contains a Federal mandate that may result in expenditures of $100 
million or more for State, local and tribal governments, in the 
aggregate, or to the private sector in any 1-year. Accordingly, EPA has 
prepared the following description of the intergovernmental 
consultation under UMRA, and Executive Order 12875 (58 FR 58093, 
October 28, 1993), entitled ``Enhancing the Intergovernmental 
Partnership.'' The basis for EPA's determination is contained in the 
economic analysis accompanying this rule, which is included in the 
public record for this action and summarized in Unit IV. of this 
preamble.
    UMRA requires that such a rule be accompanied by a statement that, 
among other things, documents that the rule is the least costly, most 
cost-effective or least burdensome alternative that achieves the 
regulatory objective. In the absence of such documentation, UMRA

[[Page 33295]]

provides that the head of the promulgating Agency may otherwise provide 
in the statement an explanation of why the least burdensome approach 
was not adopted or is inconsistent with law. The discussion in part E 
of Unit IV of this preamble describes the Agency's analysis of 
regulatory options. As this discussion, and the earlier analysis cited 
therein (c.f., Ref. 13) indicates, the Agency believes that this 
proposed action is the most cost-effective and least burdensome 
alternative to the alternatives considered in the development of the 
Pesticides and Ground-Water Strategy (Ref. 12), developed as the 
groundwork for today's proposed rule. A particularly advantageous 
feature of the chosen option is that it allows States to determine the 
most appropriate approach for preventing unreasonable adverse effects 
within their individual States. The practical alternatives are a choice 
between different kinds of Federally mandated restrictions, either 
national standards and/or risk-reduction measures (principally in the 
form of label changes) or outright cancellations of use. The principal 
disadvantage of both is that they can not take State specific issues 
into consideration, and so can be anticipated to increase the loss of 
economic benefits associated with the pesticides' use, relative to the 
impacts of SMPs. National-level measures are potentially less certain 
of meeting the regulatory objective, that is, of achieving the goal of 
preventing unreasonable levels of ground-water contamination. This 
greater uncertainty is caused by the relative inability to tailor risk-
management measures, proceeding instead on a ``lowest common 
denominator'' approach. Still another conceivable (but unanalyzed) 
option is doing nothing at the Federal level, leaving the potential for 
ground-water contamination to be addressed, if at all, by voluntary 
action and/or independent State action. This alternative was not 
analyzed because it clearly failed to meet the regulatory objective. 
Such an option that freely permits contamination would entail no direct 
regulatory costs, but the far larger reduction in the value of the 
resource must be compared to the more conventional economic impacts.
    The statement required by UMRA also requires a summary description 
of State/local/Tribal governmental input in the rule's development. 
Prior consultation with State and Tribal authorities has been 
extensive. The Pesticides and Ground Water Strategy development process 
began with a major public workshop held in 1986 in Coolfont, West 
Virginia. State Agriculture, Environment and Health agencies were among 
the participants. A second public workshop was held at Coolfont during 
the summer of 1987, also with similar participation. Beyond the 
Strategy, State regulatory officials were involved in the development 
of the subsequent Guidance beginning in 1989, when EPA sponsored 
working sessions to determine how best to guide the process of managing 
pesticide use to protect the ground water resource. Two week long 
sessions were held in Fredericksburg, Virginia during October and 
November of 1989. These sessions were actual working sessions to 
develop the document that today is the SMP guidance document. Between 
five and seven States participated in each session. Drafts of the 
guidance document were shared with all 50 State Lead Agencies for 
Pesticides, EPA Regional Offices, and other Federal agencies.
    During development of the proposed rule, many issues were discussed 
with the Water Quality Working Committee Group of the State FIFRA 
Issues Research and Evaluation Group (SFIREG) on which eight State Lead 
Agencies sit. This group meets three times per year with OPP to discuss 
water quality issues and this forum was used extensively in the early 
stages of development of the proposed rule.
    The proposed regulation itself has been provided as an initial 
draft twice to EPA's 10 regional offices and all 50 states for review 
and comment, in addition to the SFIREG Water Quality Committee and to 
SFIREG's parent body, the American Association of Pesticide Control 
Officials (AAPCO). The first round of review in fall 1994 elicited 38 
written comments from State and Tribal agencies; the second round in 
spring 1995 elicited 18 further comments. As a result of each round of 
review, the draft proposed rule was modified. These written comments 
are in the public record and were considered in the development of the 
proposed rule. Virtually all of the principal State comments and 
concerns are reflected in the discussion in Unit III of this preamble, 
and in the request for comments accompanying that Unit.
    All other UMRA requirements for the accompanying statement to a 
``significant regulatory action,'' e.g., descriptions of statutory 
authority, anticipated costs and benefits, compliance costs, are 
contained throughout this preamble, in the appropriate headings.

E. Executive Order 12898

    Pursuant to Executive Order 12898 (59 FR 7629, February 16, 1994), 
the Agency has considered environmental justice related issues with 
regard to the potential impacts of this action on the environmental and 
health conditions in low-income and minority communities. As related 
throughout this document, the approach the Agency is proposing to 
address the problem of pesticides in ground water is based on a full 
appreciation of the localized nature of the problem, and this approach 
strives to be the most effective strategy for localized protection of 
the ground-water resource. As the Strategy highlights, alternatives to 
effective local-level risk reduction measures (e.g., national-level 
regulation or no regulatory protection) are considered likely to either 
over-regulate pesticide use (causing undue economic hardship to 
affected parties) or under-protect (increasing the risk of various 
adverse health and environmental effects to specific parties).

Subpart J--Ground-Water State Management Plans

Sec. 152.180   Applicability.

    This subpart applies to any pesticide or pesticide product 
designated to be subject to the requirements and provisions of ground-
water State Management Plans by means of a Restricted Use 
Classification.

Sec. 152.183   Definitions.

    In addition to the definitions in Sec. 152.3, the following terms 
also apply to this subpart:
    Ground Water Reference Point means an environmental concentration 
of a pesticide ingredient based on any of the following:
    (1) Maximum Contaminant Levels (MCLs) established under the Safe 
Drinking Water Act; or
    (2) Health Advisories (where MCLs are not available for a 
substance); or
    (3) Water Quality Standards (where the ingredient poses adverse 
effects to ecosystems affected by closely hydrologically linked surface 
waters) under the Clean Water Act.
    Plan means a State Management Plan developed for the purpose of 
managing the use of a pesticide in order to prevent unreasonable risks 
of ground water contamination.
    State means each of the 50 States, Puerto Rico, the U.S. Virgin 
Islands, the District of Columbia, Guam, American Samoa and other 
Pacific Island Territories of the United States, as well as Indian 
Lands under Tribal jurisdiction.

Sec. 152.185   Restriction.

    (a) Restriction. A pesticide or pesticide product classified for 
restricted use subject to a State Management Plan may be used only in 
accordance with the provisions and requirements of an Agency-approved 
State Management Plan, after a date 33 months from the date the 
pesticide or product is so classified. Such a pesticide or pesticide 
product may not be sold or used after that date within the boundaries 
of a State without an Agency-approved State Management Plan.
    (b) Labeling. (1) Upon classification of a pesticide for restricted 
use, subject to ground-water State Management Plans, each registrant of 
a product subject to that classification shall, within 12 months after 
the date of that classification by final Agency rule, submit for such 
product:
    (i) A copy of the labeling amended to include the statement 
specified in Sec. 156.137(a)(2)(ii) of this chapter.
    (ii) A statement that the registrant will comply with the labeling 
requirements prescribed by the Agency by the effective date of this 
rule. The Agency will regard such statement to be a report under the 
Act. The Agency may deny registration or initiate cancellation 
proceedings if a registrant fails to comply with the timetables 
established in this section.
    (2) A product whose labeling bears directions for end use and that 
has been classified as subject to ground-water State Management Plans 
must be labeled in accordance with the requirements of Sec. 156.10 of 
this chapter after the effective date of the restriction.
    (c) Distribution and sale of classified products. No product with a 
use classified for restricted use, subject to ground-water State 
Management Plans, may be distributed or sold by a retailer or other 
person after the effective date of the restriction, unless the product 
bears a label or labeling which contains the terms of the 
classification and otherwise complies with paragraph (b)(2) of this 
section.

Sec. 152.187   Submission and approval of ground-water State Management 
Plans.

    If any State, at any time after the classification of a pesticide 
or pesticide product to be subject to State Management Plans by final 
rule, wishes to establish a ground-water State Management Plan for such 
a pesticide or pesticide product, that State shall submit a proposed 
Plan for that purpose to the Administrator. The Administrator will 
approve the Plan submitted by any State if, in the Administrator's 
judgement, the Plan meets the requirements of Sec. 152.190.
    (a) Schedule. A State that wishes to implement a Plan on the 
effective date of the State Management Plan restriction shall submit a 
proposed Plan, along with the administrative record accompanying 
development of the proposed Plan to the appropriate EPA region under 40 
CFR 1.7, before a date 24 months from the date a pesticide or product 
is classified. The submission shall include an electronic file in 
Wordperfect 5.1 or higher or ASCII for all material. The Administrator 
will review such submittals and approve or disapprove Plans within 9 
months of receipt of a complete submittal.
    (b) Review. Upon receipt of a proposed State Plan submitted for EPA 
approval, the Administrator or a designee will first review the 
proposed Plan to determine that all requirements as provided in 
Sec. 152.190 have been addressed. Upon completion of this review, the 
Administrator will notify the State in writing of the initial 
determination of the completeness of the submission. In the event that 
the Administrator determines that the submission fails to address all 
requirements, the Administrator will request the State revise its 
submission to provide the missing components. Once the Administrator is 
satisfied that the submission is complete, full evaluation of the 
submission will proceed.
    (c) Approval. Upon completion of the review of the submission, if 
the Administrator finds that the Plan meets the requirements of 
Sec. 152.190, then the Administrator will publish a Notice of Approval 
in the Federal Register and a letter of notification to the State 
official designated as State Liaison, pursuant to Sec. 152.190(b), 
informing of the approval.
    (d) Disapproval. If, after completion of the review of the 
submission, the Administrator finds that the submission fails to meet 
the requirements of Sec. 152.190, the Administrator shall notify the 
State Liaison by letter that EPA will not approve the Plan as 
submitted, and specifying the deficiencies in the Plan that prevent its 
approval. If, after further consultation, the Administrator still finds 
that the submission fails to meet the requirements, the Administrator 
will publish a notice in the Federal Register announcing the 
disapproval of the Plan and including the reasons for finding the Plan 
inadequate pursuant to Sec. 152.190. In this event, sale or use in the 
State of the pesticide that is the subject of the Plan shall be 
prohibited 33 months after the promulgation of a rule classifying the 
pesticide as subject to a ground-water State Management Plan.

Sec. 152.190   Specifications and requirements of a ground-water State 
Management Plan.

    The Administrator shall approve the State Management Plan submitted 
by any State, or any modification thereof, if in the Administrator's 
judgement, the Plan fulfills the following requirements.
    (a) State's philosophy and goals toward protecting ground water. An 
acceptable Plan must, to the satisfaction of the Administrator, contain 
a description of the State's ground-water protection philosophy and 
goals regarding pesticide management, including an explanation how its 
philosophy and goals will be no less protective than EPA's goal of 
preventing adverse effects to human health and the environment and 
protecting the environmental integrity of the nation's ground water.

[[Page 33297]]

    (b) Roles and responsibilities of State agencies. An acceptable 
Plan must, to the satisfaction of the Administrator:
    (1) Identify and describe both the general responsibility of, and 
the specific technical and administrative tasks to be performed by, 
each participating agency responsible for the development and 
implementation (including enforcement) of the Plan, including a 
description of how the State agencies intend to use the programs and 
expertise of Federal agencies in carrying out the Plan.
    (2) Identify a Liaison who will serve as a single contact point for 
all formal communications concerning the Plan process between EPA and 
the State, including responsibility for the transmittal and receipt of 
official correspondence and information.
    (3) Describe the coordination mechanisms between all participating 
State agencies, local entities, and appropriate Federal agencies.
    (4) Describe how local governments are included in activities under 
the Plan. When local governments have authority to address State 
ground-water-related objectives and priorities, the State must 
demonstrate that program coordination, guidance, or oversight is 
provided.
    (5) Contain official concurrences from the directors of all State 
agencies with responsibilities under the Plan stating their agreement 
with the Plan, and their commitment to carry out their responsibilities 
under the Plan.
    (6) Discuss any relevant inter-State multi-jurisdictional 
coordination, including how any multi-jurisdictional issues will be 
resolved for purposes of implementing the Plan.
    (c) Legal authority. An acceptable Plan must, to the satisfaction 
of the Administrator:
    (1) Contain regulatory authorities that are sufficient to 
accomplish the objectives of the Plan, established in paragraph (a) of 
this section.
    (2) Specify the legal authorities of the State to implement the 
Plan successfully and specify the State's authority to impose 
preventive measures, its remedial action authority and its compliance 
and enforcement authorities, citing all relevant State laws and 
regulations and including Federal legislation, regulations and program 
delegation, available to the State.
    (3) Identify the specific authorities that will be used to carry 
out the specific commitments made in the Plan. The State must 
specifically identify the authority to conduct or require others to 
conduct monitoring, prohibit use in specific areas, close public wells, 
or supply or require others to supply alternative sources of water, 
where such actions are elements of the Plan, must be identified.
    (d) Resources. An acceptable Plan must, to the satisfaction of the 
Administrator, demonstrate there are adequate resources available to 
implement and enforce the program. Resources include technical 
expertise and personnel, physical and operational capabilities, and 
funding. The Plan must demonstrate there is an adequate match between 
revenues and proposed expenditures and that the necessary expertise is 
available.
    (e) Basis for assessment and planning. An acceptable Plan must, to 
the satisfaction of the Administrator, specify the State's approach and 
activities to assess vulnerability for the geographic area in which the 
State intends to allow pesticide use, identifying the sources of all 
such data. The State shall specifically describe the State's available 
pesticide use data (e.g., geographic use and application rates) and how 
it will be factored into assessing vulnerability.
    (f) Monitoring. An acceptable Plan must, to the satisfaction of the 
Administrator, demonstrate that monitoring activities (including 
ground-water monitoring) performed pursuant to the Plan are appropriate 
for the purposes of the Plan, with assurances that the activities will 
be carried out adequately. Specifically, an acceptable Plan must 
identify and describe key elements of the monitoring program, including 
the scope and objective (in relation to the purposes of the Plan) of 
such monitoring, design and justification (including the number of 
sites to be sampled, the number of samples to be taken and the 
frequency of sampling) of such monitoring, monitoring protocols, 
quality assurance/quality control, sampling methodology, analytical 
methods, and analytes. Such description must make clear how the 
placement of monitoring sites relates to the State's priorities for 
protecting ground water, and will allow evaluation of the effectiveness 
of prevention and response measures specified in paragraphs (g) and (h) 
of this section. Monitoring performed for the purpose of fulfilling 
this requirement must be performed in accordance with an EPA-approved 
Quality Assurance Project Plan (as described in Chapter 5.4.2 of 
Appendix B, ``Assessment, Prevention, Monitoring and Response 
Components of State Management Plans,'' to the Guidance for Pesticides 
and State Management Plans (EPA 735-B-93-005c, February 1994). This 
incorporation by reference was approved by the Director of the Federal 
Register in accordance with 5 U.S.C. 552(a) and 1 CFR part 51. Copies 
may be obtained from the Public Response and Program Resources Branch, 
Field Operations Division (7506C), Office of Pesticide Programs, 
Environmental Protection Agency, 401 M St., SW., Washington, DC 20460. 
Copies may be inspected at the above address or at the Office of the 
Federal Register, 800 North Capitol St., NW., suite 700, Washington, 
DC. Good Laboratory Practice Standards (40 CFR part 160) do not apply 
to monitoring performed for the purpose of fulfilling this requirement.
    (g) Prevention actions. An acceptable Plan must, to the 
satisfaction of the Administrator, specify the actions a State will 
take to manage the use of the pesticide classified for use subject to 
the Plan, to fulfill the State's goals and principles enunciated 
pursuant to paragraph (a) of this section and will otherwise prevent 
unreasonable adverse effects to human health and protect the 
environmental integrity of the nation's ground-water resources.
    (h) Response to detections of pesticides. An acceptable Plan must, 
in the judgement of the Administrator, adequately specify the measures 
that the State will take (and the circumstances under which the State 
will take them) to respond to contamination so that Ground Water 
Reference Points are not reached, and specify the actions the State 
will take in the event Reference Points are met or exceeded. This 
description must be presented in the form of a general corrective 
response scheme, illustrating the State's capacity for timely, 
coordinated response to contamination.
    (i) Enforcement mechanisms. An acceptable Plan must, to the 
satisfaction of the Administrator, demonstrate that the State's 
enforcement authorities and capabilities are adequate to implement and 
to monitor compliance with the specific measures included in the Plan, 
describing authorities and capabilities that are intended to protect 
ground water from contamination and response actions where 
contamination has already occurred. Enforcement authority must be 
identified by the State, and the roles and responsibilities of each 
State agency must be defined, including how coordination of enforcement 
capabilities within agencies will work to prevent and respond to 
contamination.
    (j) Public awareness and participation. An acceptable Plan must, to 
the satisfaction of the Administrator, demonstrate that there is notice 
and opportunity for public comment within the process of Plan 
development, and will be informed of significant Plan

[[Page 33298]]

implementation activities. This demonstration must:
    (1) Describe the public role regarding development of the Plan and 
decision-making in implementing the Plan, and identify or describe 
existing legal requirements within the State that would ensure public 
participation in the process (i.e., an Administrative Procedure Act 
requiring notice and comment, etc.). If no such legal requirements 
exist within the State, the Plan must describe any other public 
participation process that the State uses in the development of the 
Plan.
    (2) The Plan must also specify the level of detection in ground 
water that is considered by the State to be of such significance that 
the State will inform the public. Indicate how, when, and by whom the 
public will be informed of detections in ground water that are 
considered significant, providing for, at a minimum:
    (i) The notification of any well owner of any detections in ground 
water; and
    (ii) The notification of all users of any detections above the 
reference point.
    (3) Include a description of the process and means of communication 
by which the public will be made aware of important regulatory actions 
taken under the Plan.
    (k) Information dissemination. An adequate Plan must, to the 
satisfaction of the Administrator, describe the means by which measures 
prescribed pursuant to the Plan will be communicated to pesticide users 
and all other interested parties. A plan must:
    (1) Describe how information regarding prevention measures (e.g., 
use limitations and precautions) will be relayed to the appropriate 
audiences.
    (2) Describe how pesticide users will be trained or educated in how 
to comply with requirements of applying a pesticide where use is 
governed by the Plan.
    (3) Identify the targeted parties and discuss how information will 
be relayed.
    (4) Explain why the information dissemination approach is 
appropriate for the type of contamination prevention actions being 
employed, and the education and/or awareness of the targeted audience 
is required.
    (5) Describe how information will be updated as requirements 
change. Such discussion should include the form these updates will take 
and the distribution methods. The Plan should also discuss any existing 
mechanisms (i.e., Memoranda of Understanding, cooperative agreements, 
etc.) between the State and other entities that will be involved in 
this effort.
    (l) Records and reporting. An adequate Plan must, to the
FR Doc. 96-16173 Pesticides and Ground Water State Management Plan Regulation
 
satisfaction of the Administrator:
    (1) Include a commitment by the State to maintain essential records 
relating to Plan implementation for a period of at least 6 years. The 
information maintained must include, but is not limited to, records on 
any monitoring or sampling conducted, results of analyses, issuance of 
permits, types and numbers of enforcement actions taken, records of any 
site-specific regulatory actions, and administrative actions. The State 
must commit to promptly make available to the Agency, upon request, 
records related to the development or implementation of the Plan.
    (2) Commit to developing and submitting to the appropriate Regional 
Office a Plan Biennial Report, as described in Sec. 152.191(a), and to 
report any significant findings to the appropriate Agency Regional 
Office.
    (3) Commit to submitting with each report to EPA a signed 
certification, worded as follows:

    I certify under penalty of law that I have personally examined 
and am familiar with the information submitted herein and based on 
my inquiry of those individuals immediately responsible for 
obtaining the information, I believe the submitted information is 
true, accurate and complete. I am aware that there are significant 
penalties for submitting false information, including the 
possibility of fine and imprisonment. See 18 U.S.C. section 1001 and 
7 U.S.C. section 136).

Sec. 152.191   Evaluation of State Management Plan Implementation.

    Any State Management Plan approved under Sec. 152.190 shall be 
subject to periodic evaluations of its implementation by the Agency, in 
order to assure implementation of the Plan consistent with its goals 
and commitments, to determine the environmental effectiveness and the 
level of ground-water protection provided by the Plan, and to ensure a 
minimum level of national consistency.
    (a) Biennial Report. A Biennial Report, as described in 
Sec. 152.190 (l)(2), must be developed and submitted by the State in 
order to maintain Agency approval, and will be used by the Agency and 
by State officials to evaluate a State's effectiveness in protecting 
its ground-water resources from pesticide contamination. The State 
shall prepare the Biennial Report according to the provisions of 
Chapter 5 of Appendix A, ``Review, Approval and Evaluation of State 
Plans,'' to the Guidance for Pesticides and State Management Plans (EPA 
735-B-93-005b, February 1994).
    (b) Evaluation reporting requirements. The Biennial Report must be 
approved by State officials directing the key State agencies that play 
a role in implementing the Plan. The Biennial Report must be submitted 
in October of alternate years, starting in October [of the year 4 years 
after date of publication of the final rule] to the appropriate Agency 
Regional Office. The State may submit a single Biennial Report in the 
event it implements Plans for more than one classified pesticide. In 
that event, the report must include programmatic and environmental 
evaluations addressing each approved Plan. States will also submit a 
programmatic and an environmental evaluation that addresses any 
progress made in implementing the Plan.

Sec. 152.193   Amendment of State Management Plans.

    (a) The State will amend an approved Plan as part of the Biennial 
Report required under Sec. 152.191(a) when:
    (1) The evaluation performed pursuant to Sec. 152.191 demonstrates 
that the provisions in the Plan do not adequately protect the ground-
water resource from pesticide contamination.
    (2) A change in the legal (statutory or regulatory) and enforcement 
framework for Plan development and implementation necessitates a change 
in the Plan.
    (3) A State, through experience, finds more effective ways to 
assess ground-water contamination, to prevent and respond to 
contamination, and to educate affected parties or disseminate 
information.
    (4) Changes in pesticide management measures or approaches become 
necessary as a result of significant changes in crops or crop 
production systems and technologies within the State.
    (5) Roles and responsibilities of State agencies involved in the 
implementation of the Plan change so as to necessitate a change in the 
Plan.
    (b) If a State is aware that an amendment is needed, then that 
amendment should be submitted as part of the Plan Biennial Report. In 
addition, if the Regional Office that is the recipient of that Report 
determines through the evaluation process that the Plan needs to be 
updated, then the Regional Administrator of that region, or a designee, 
can initiate the updating process by requesting that the State submit a 
Plan Update Report. In every case, the Update Report must include:
    (1) A description of the proposed changes in the Plan.
    (2) An explanation of why the changes are necessary.
    (3) An analysis of the impact the changes will have on the other

[[Page 33299]]

components of the Plan, the implementation of the Plan and the 
protection of the resource.
    (4) If changes will affect pesticide users, a description of how 
users will be alerted to the changes in the Plan.
    (5) Concurrences by all officials directing the key State agencies.
    (6) If changes are significant, a description of how the State 
received public input on changes to the Plan, and the administrative 
record developed in the course of changing the Plan. Amendments to 
Plans must be concurred or approved by the Regional Administrator.

Sec. 152.195   Withdrawal of approval of a State Management Plan.

    (a) If, in the judgement of the Administrator or a designee, 
either:
    (1) A State fails to demonstrate that it is satisfactorily 
implementing the Plan; or
    (2) A State's Plan is not protecting ground water from 
contamination at or above ground water reference points (as specified 
in Sec. 152.198); or
    (3) A State fails to address deficiencies identified by the Plan 
evaluation through updating the Plan and/or improving implementation of 
the Plan; or
    (4) A State fails to submit a biennial report;
he or she shall notify the designated State Liaison, named pursuant to 
Sec. 152.190(b), and relevant State administrators of the Agency's 
concerns. In that event, the State will have 90 days to respond to 
these deficiencies in its Pesticide Plans, either through the Plan 
updating process or by demonstrating to the Region that the Plan is 
being satisfactorily implemented.
    (b)(1) If the Administrator determines that the State has failed to 
address the deficiencies identified by the Agency or has failed to 
correct the deficiencies, the Administrator shall notify the officials 
directing the key State agencies involved in implementing the Plan and 
the designated State Liaison by letter that withdrawal of Agency 
approval is being considered. The notice will include:
    (i) A statement concerning the potential withdrawal of Agency 
approval of the Plan.
    (ii) A listing of the deficiencies of the Plan or a description of 
the failure of the Plan or its implementation to protect ground water.
    (iii) A brief summary of the events that led to the withdrawal 
notice.
    (iv) Dates by which the State can respond to the deficiencies to 
stop the withdrawal process.
    (2) The State must respond to the notice within 30 days of receipt 
of the notice in writing with a commitment to address the deficiencies 
in the Plan itself or in its implementation. If the State disagrees 
with the judgement or the findings of the Administrator in the initial 
notice described in paragraph (b) of this section, the State may 
request to meet with the Administrator within 60 calendar days from the 
time the EPA Administrator sends the letter of potential withdrawal to 
the Administrators of the key State agencies.
    (3) If, in the Administrator's judgement, continued use of the 
pesticide within the State presents unreasonable adverse effects on the 
environment because of the deficiencies cited pursuant to paragraph 
(b)(1) of this section, the Administrator may prohibit further sale and 
use of the pesticide in the State until the Agency and the State reach 
an agreement on how to address the Plan's deficiencies. Such a 
prohibition shall be published in a Federal Register notice describing 
the basis for the Administrator's findings, and soliciting comment 
thereon. After addressing any public comment, the Administrator may 
take final action temporarily prohibiting use of the pesticide in the 
State.
    (c) If the State does not respond to the notice that withdrawal of 
approval is being considered or fails to address the deficiencies 
identified in the notice to the satisfaction of the Administrator, the 
Administrator will send a formal letter to the officials directing the 
key State agencies and the State Liaison indicating that EPA is 
publishing a Federal Register Notice proposing to withdraw the 
Pesticide Plan. In the event the State does not respond to this notice, 
the Administrator will publish a Federal Register Notice to provide an 
opportunity for public comment on withdrawal of the Plan. After 
addressing any public comments, the Region will publish a Notice of 
Withdrawal in the Federal Register and prohibit the sale and use of the 
pesticide in the State.
    (d) Upon publication of the final Notice of Withdrawal in the 
Federal Register, sale and use of the pesticide within the boundaries 
of the State will be prohibited.

stated in terms which can be easily read and understood by the average 
person likely to use or to supervise the use of the pesticide. When 
followed, directions must be adequate to protect the public from fraud 
and from personal injury and to prevent unreasonable adverse effects on 
the environment.
    (b) Placement of directions for use. Directions may appear on any 
portion of the label provided that they are conspicuous enough to be 
easily read by the user of the pesticide product. Directions for use 
may appear on printed or graphic matter which accompanies the pesticide 
provided that:
    (1) If required by the Agency, such printed or graphic matter is 
securely attached to each package of the pesticide, or placed within 
the outside wrapper or bag.
    (2) The label bears a reference to the directions for use in 
accompanying leaflets or circulars, such as ``See directions in the 
enclosed circular.''
    (3) The Administrator determines that it is not necessary for such 
directions to appear on the label.
    (c) Exceptions to requirement for direction for use--(1) Detailed 
directions for use may be omitted from labeling of pesticides which are 
intended for use only by manufacturers of products other than pesticide 
products in their regular manufacturing processes, provided that:

only in manufacturing processes and specifies the type(s) of products 
involved.
    (ii) Adequate information such as technical data sheets or 
bulletins, is available to the trade specifying the type of product 
involved and its proper use in manufacturing processes.
    (iii) The product will not come into the hands of the general 
public except after incorporation into finished products.
    (iv) The Administrator determines that such directions are not 
necessary to prevent unreasonable adverse effects on man or the 
environment.
    (2) Detailed directions for use may be omitted from the labeling of 
pesticide products for which sale is limited to physicians, 
veterinarians, or druggists, provided that:
    (i) The label clearly states that the product is for use only by 
physicians or veterinarians.
    (ii) The Administrator determines that such directions are not 
necessary to prevent unreasonable adverse effects on man or the 
environment.
    (iii) The product is also a drug and regulated under the provisions 
of the Federal Food, Drug and Cosmetic Act.
    (3) Detailed directions for use may be omitted from the labeling of 
pesticide products which are intended for use only by formulators in 
preparing pesticides for sale to the public, provided that:
    (i) There is information readily available to the formulators on 
the composition, toxicity, methods of use, applicable restrictions or 
limitations, and effectiveness of the product for pesticide purposes.
    (ii) The label clearly states that the product is intended for use 
only in manufacturing, formulating, mixing, or repacking for use as a 
pesticide and specifies the type(s) of pesticide products involved.
    (iii) The product as finally manufactured, formulated, mixed, or 
repackaged is registered.
    (iv) The Administrator determines that such directions are not 
necessary to prevent unreasonable adverse effects on man or the 
environment.

156.121   Contents of directions of general use.

    The directions for use shall include the following, under the 
headings ``Directions for Use'':
    (a) The statement of use classification as prescribed in paragraph 
(j) of this section immediately under the heading ``Directions for 
Use.''
    (b) Immediately below the statement of use classification, the 
statement ``It is a violation of Federal law to use this product in a 
manner inconsistent with its labeling.''
    (c) The site(s) of application, as for example the crops, animals, 
areas, or objects to be treated.
    (d) The target pest(s) associated with each site.
    (e) The dosage rate associated with each site and pest.
    (f) The method of application, including instructions for dilution, 
if required, and type(s) of application apparatus or equipment 
required.
    (g) The frequency and timing of applications necessary to obtain 
effective results without causing unreasonable adverse effects on the

    (h) Worker protection statements meeting the requirements of 
subpart K of this part.
    (i) Specific directions concerning the storage and disposal of the 
pesticide and its container, meeting the requirements of 40 CFR part 
165. These instructions shall be grouped and appear under the heading 
``Storage and Disposal.'' This heading must be set in type of the same 
minimum sizes as required for the child hazard warning. (See Table in 
Sec. 162.10(h)(1)(iv))
    (j) Any limitations or restrictions on use required to prevent 
unreasonable adverse effects, such as:
    (1) Required intervals between application and harvest of food or 
feed crops.
    (2) Rotational crop restrictions.
    (3) Warnings as required against use on certain crops, animals, 
objects, or in or adjacent to certain areas.
    (4) [Reserved]
    (5) For restricted use pesticides, a statement that the pesticide 
may be applied under the direct supervision of a certified applicator 
who is not physically present at the site of application but 
nonetheless available to the person applying the pesticide, unless the 
Agency has determined that the pesticide may only be applied under the 
direct supervision of a certified applicator who is physically present.
    (6) Other pertinent information which the Administrator determines 
to be necessary for the protection of man and the environment.

Sec. 156.135   Statements of use classification.

    (a) Requirement. Each product bearing one or more uses that has 
been classified for restricted use must bear a classification statement 
on the label of the product, and also in any supplemental labeling that 
accompanies the product in sale or distribution. A product that bears 
only unclassified uses as described in Sec. 152.160 or uses classified 
for general use is not required to bear any classification statement. 
Restricted use statements are set out in Sec. 156.137.
    (b) Products bearing mixed classified uses. A product for which 
some uses are not classified, and other uses are classified for general 
use or for restricted use must have a separate registration for uses 
that are restricted, except that a product bearing restricted uses may 
also bear unclassified or general uses in addition to the restricted 
uses. A product bearing mixed restricted uses and other uses is 
considered a restricted use product.
    (c) Placement of classification statements. (1) Statements of 
restricted use classification must be located at the top of the front 
panel of the label (the ``Restricted Use'' area), and in a similarly 
prominent location in supplemental labeling. No other label statements 
shall appear above the restricted use statements, and no other 
statements than those prescribed by the

[[Page 33301]]

Agency shall appear in the restricted use area of the label.
    (2) The restricted use statements shall be distinguished from 
surrounding label text by suitable means, such as white space or a box 
around the statements. The words ``Restricted Use Pesticide'' shall

Sec. 156.10(h)(1)(iv).

Sec. 156.136   General use statements. [Reserved]

Sec. 156.137   Restricted use statements.

    (a) A product that is classified for restricted use must bear, on 
the front panel in accordance with Sec. 156.135(c), the statements in 
paragraphs (a)(1) and (a)(2) of this section.
    (1) The phrase, ``Restricted Use Pesticide.''
    (2) Immediately below the phrase ``Restricted Use Pesticide,'' a 
statement of the reason for the restricted use classification. This 
statement will describe the characteristic of the pesticide, its 
formulation, or its use pattern, that is the basis for the 
classification. These characteristics include acute or chronic 
toxicity, environmental fate (biodegradability, leaching potential, 
etc.), or non-target organism toxicity. The Agency will prescribe the 
nature and wording of the statement.
    (i) A product that is restricted to use by certified applicators 
(for example, pesticides and uses listed in Sec. 152.170) must bear the 
statement, ``For retail sale to and use only by Certified Applicators 
or persons under their direct supervision and only for those uses 
covered by the Certified Applicator's certification.''
    (ii) A product that is classified for restricted use subject to a 
ground-water State Management Plan (SMP) under subpart J of part 152 of

Linuron; Proposed Revision of Tolerances

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: EPA has completed the reregistration process and issued a 
Reregistration Eligibility Decision document (RED) for the herbicide 
linuron (3-(3,4-dichlorophenyl)-1-methoxy-1-methylurea). In the 
reregistration process, all information to support a pesticide's 
continued registration is reviewed for adequacy and, when needed, 
supplemented with new scientific studies. This proposed action updates 
and corrects the tolerance actions indicated in the RED. Based on the 
RED, tolerance assessment for linuron, and subsequent comments and 
analyses, EPA is proposing to revise food tolerance levels, revoke some 
linuron tolerances, and to revise the tolerance expression for residues 
of linuron (40 CFR 180.184).
DATES: Written comments, identified by the docket number [OPP-300424], 
must be received on or before August 26, 1996.

ADDRESSES: By mail, submit written comments to: Public Response and 
Program Resources Branch, Field Operations Division (7506C), Office of 
Pesticide Programs, Environmental Protection Agency, 401 M St., SW., 
Washington, DC 20460. In person, bring comments to: Rm. 1132, CM #2, 
1921 Jefferson Davis Hwy., Arlington, VA. Information submitted and any 
comment(s) concerning this notice may be claimed confidential by 
marking any part or all of that information as ``Confidential Business 
Information'' (CBI). Information so marked will not be disclosed except

SUPPLEMENTARY INFORMATION:

[[Page 33055]]

I. Legal Authorization

    The Federal Food, Drug, and Cosmetic Act (FFDCA) [21 U.S.C. 301 et 
seq.] authorizes the establishment of tolerances (maximum legal residue 
levels) and exemptions from the requirement of a tolerance for residues 
of pesticide chemicals in or on raw agricultural commodities pursuant 
to section 408 [21 U.S.C. 346(a)]. Without such tolerances or 
exemptions, a food containing pesticide residues is considered to be 
``adulterated'' under section 402 of the FFDCA, and hence may not 
legally be moved in interstate commerce [21 U.S.C. 342]. To establish a 
tolerance or an exemption under section 408 of the FFDCA, EPA must make 
a finding that the promulgation of the rule would ``protect the public 
health'' [21 U.S.C. 346a(b)]. To establish food additive regulations 
(FARs) to cover pesticide residues in processed foods under section 409 
of FFDCA, EPA must determine that the proposed use of the food additive 
will be safe (21 U.S.C. 348). For a pesticide to be sold, distributed, 
and used in the production of food crops, animals, or processed food, 
the pesticide must not only have appropriate tolerances or FARs under 
the FFDCA, but also must be registered under the Federal Insecticide, 
Fungicide, and Rodenticide Act (FIFRA, 7 U.S.C. 136 et seq.). In 1988, 
Congress amended FIFRA and required EPA to review and reassess the 
potential hazards arising from currently registered uses of pesticides 
registered prior to November 1, 1984. As part of this process, the 
Agency must determine whether a pesticide is eligible for 
reregistration and if any subsequent actions are required to fully 
attain reregistration status. EPA has chosen to include in the 
reregistration process a reassessment of existing tolerances or 
exemptions from the need for a tolerance. Through this reassessment 
process, EPA can determine whether a tolerance must be amended, 
revoked, or established, or whether an exemption from the requirement 
of one or more tolerances must be amended or is necessary.
    The procedure for establishing, amending, or repealing tolerances 
or exemptions from the requirement of tolerances is set forth in the 
Code of Federal Regulations at 40 CFR parts 177 through 180. The 
Administrator of EPA or any person may initiate an action proposing to 
establish, amend, revoke, or exempt a tolerance for a pesticide 
registered for food uses. Each petition or request for a new tolerance, 
an amendment to an existing tolerance, or a new exemption from the 
requirement of a tolerance must be accompanied by a fee or a request 
for a waiver of such fee. Current Agency policy on tolerance actions 
arising from the reregistration process is to administratively process 
some actions without requiring payment of a fee; this waiver of fees 
applies to revisions or revocations of established tolerances, and to 
proposed exemptions from the requirement of a tolerance if the proposed 
exemption requires the concurrent revocation of an established 
tolerance. Comments submitted in response to the Agency's published 
proposals are reviewed; the Agency then publishes its final 
determination regarding the specific tolerance actions.

II. Regulatory Background and Proposed Actions

A. Regulatory Background

    The proposals described in this action follow the Agency's 
tolerance reassessment that was completed and included in the RED for 
linuron dated March 1995. While the reassessment determined that many 
tolerances established for linuron are adequate and supported by 
sufficient data, changes are needed to other linuron tolerances for 
various reasons, including: increasing or decreasing tolerances based 
on new data and revising commodity terminology, crop group 
designations, and definitions that are not in accordance with the 
revised crop group regulation (40 CFR part 180, 60 FR 26625, May 17, 
1995) or with Table II of Subdivision O of the Pesticide Assessment 
Guidelines.
    The section of the CFR to be amended by this document is 
Sec. 180.184.

B. Proposed Actions

    1. Tolerance expression. The tolerance expression under 40 CFR 
Sec. 180.184 would be revised to: ``Tolerances are established for the 
combined residues of the herbicide linuron (3-(3,4-dichlorophenyl)-1-
methoxy-1- methylurea) and its metabolites convertible to 3,4-
dichloraniline, calculated as linuron....''.
    The food tolerances currently listed in 40 CFR 180.184(a) and (b) 
are for residues of linuron per se. Plant and animal metabolism studies 
indicate the presence of unidentified metabolites of linuron that are 
hydrolyzed to 3,4-dichloroaniline (3,4-DCA) under the enforcement 
analytical method. Since the Agency believes in this case that the 
metabolites converted to 3,4-DCA are unlikely to be more toxic than the 
parent compound, and since the enforcement analytical method detects 
compounds convertible to 3,4-DCA, it is reasonable to express the 
tolerance as the combined residues of linuron and its metabolites 
convertible to 3,4-DCA. Because of the very low levels of 3,4-DCA 
found, the Agency has determined that 3,4-DCA poses no greater than a 
negligible risk in connection with the registered use of linuron and it 
is not necessary to regulate 3,4-DCA separately.
    Adequate enforcement methods are available for the determination of 
linuron residues of concern in/on plant and animal tissues. The current 
enforcement methods determine linuron and all metabolites hydrolyzable 
to 3,4-DCA.
    2. Tolerance revocations. The Agency proposes to revoke the 
tolerances for: barley, forage; barley, grain; barley, hay; barley, 
straw; corn, pop, fodder; corn, pop, forage; oats, forage; oats, grain; 
oats, hay; oats, straw; rye, forage; rye, grain; rye, hay; and rye, 
straw. There are no registered products for these uses, and it is the 
Agency's policy to revoke tolerances in such cases.
    In addition, the Agency proposes to revoke the linuron tolerance 
for parsnips, tops. This commodity is no longer listed as a raw 
agricultural commodity of parsnips, since it has been determined to be 
an insignificant feed item (see Table II of Subdivision O of the 
Pesticide Assessment Guidelines).
    3. Revisions to tolerances and food and feed additive regulations. 
The proposed increases and decreases in linuron tolerances are based on 
new data which indicate that a change is needed in the tolerances. To 
determine whether the proposed tolerance changes are protective of the 
public health, EPA considered all available health effects data. 
Dietary exposure resulting from the changes in this proposed action are 
protective of the public health and do not result in an unreasonable 
chronic or acute risk.
    The reference dose (RfD) is established at 0.0077 mg/kg body 
weight/day based on a no-observed-effect-level (NOEL) of 0.77 mg/kg 
body weight/day for hematological changes and is derived from a 1-year 
chronic toxicity study in dogs. An uncertainty factor of 100 was used 
to account for interspecies extrapolation and intraspecies variability. 
Chronic dietary exposure to the general population with existing and 
proposed tolerances utilize only 2 percent of the RfD. For the two 
subgroups with the highest exposures, non-nursing infants less than 1 
year old and children 1 through 6 years, residues are expected to 
utilize 6 percent and 4 percent of the RfD, respectively.
    The acute dietary toxicological endpoint is based on a NOEL of 25 
mg/

[[Page 33056]]

kg body weight/day, derived from a developmental toxicity study in 
rabbits. Acute, high-end, exposure to women of childbearing age 
(females 13 years of age or older) results in a Margin of Exposure 
(MOE) of 1,667 for developmental toxicity. The Agency generally 
considers an MOE of 100 adequate to protect the public health. Thus, 
dietary exposure to linuron is not expected to result in an 
unreasonable acute effect.
    The Agency considers that linuron ``induces cancer'' within the 
meaning of section 409 of the FFDCA, based on a dose-related increase 
in interstitial cell hyperplasia and adenomas in a two-year rat feeding 
study, and hepatocellular tumors in a two-year mouse feeding study. 
However, the Agency believes that the weight of evidence for the 
carcinogenic potential of linuron in humans is weak and it should not 
be regulated using a linearized multi-stage risk assessment model. 
Therefore, no quantitative assessment of the dietary cancer risk has 
been conducted for linuron; however, such risk is considered to be 
negligible.
    The following section describes the proposed substantive changes in 
the linuron tolerances for food or feed additive regulations.
    a. Field corn grain. EPA has reviewed new data analyzed by a method 
with a lower level of quantitation (0.05 ppm). These data support a 
lower linuron tolerance on field corn grain. The Agency therefore 
proposes to lower the linuron tolerance on field corn grain from 0.25 
ppm to 0.1 ppm.
    b. Field corn fodder (stover). The Agency proposes to increase the 
tolerance on corn, field, fodder from 1 ppm to 6 ppm. A review of data 
based on residue trials indicated the presence of residues ranging from 
0.1 to 5.5 ppm.
    c. Livestock commodities. For meat, fat, and meat byproducts of 
cattle, goats, hogs, horses, and sheep, the established tolerances are 
set at 1.0 ppm. Based on its review of data on residues of linuron in 
these commodities, which show that residues in meat, fat, and meat 
byproducts (except kidney and liver) are at least an order of magnitude 
lower than previously believed, the Agency proposes to lower the 
current tolerances for the meat, fat, and meat byproducts (excluding 
liver and kidney) of cattle, goats, hogs, horses, and sheep to 0.1 ppm, 
and to establish tolerances for the liver and kidney of cattle, goats, 
hogs, horses, and sheep at 1.0 ppm.
    d. Potatoes. The Agency proposes to reduce the tolerance on 
potatoes from 1 ppm to 0.2 ppm. Residue data submitted to support 
reregistration of the potato use support this reduction.
    e. Wheat. EPA has reviewed new data using an analytical method with 
a lower level of quantitation (0.05 ppm). These data support a lower 
linuron tolerance, and therefore the Agency proposes to lower the 
linuron tolerance on wheat grain from 0.25 ppm to 0.1 ppm. The Agency 
also proposes to raise the linuron tolerance on wheat straw from 0.5 
ppm to 2.0 ppm based on a reassessment of residue data which showed 
residues of up to 2 ppm on wheat straw.
    4. Changes from the RED--a. Food additive regulations related to 
potatoes. The RED stated that food and feed additive regulation 
petitions (409 tolerances) would be required for potatoes, granules; 
potatoes, chips; and potatoes, waste from processing. As a result of 
the revised Agency policy (60 FR 31300, June 14, 1995) or with Table II 
of Subdivision O concerning when a food or feed additive regulation is 
needed, the Agency has re-examined its decision in the Linuron RED on 
food or feed additive regulations for potato-related commodities. EPA 
has also considered new data on residue levels of linuron in potatoes 
submitted to support reregistration. These data show that residues of 
linuron in potato processed commodities are unlikely to exceed the 
section 408 tolerance. Therefore, food or feed additive regulations are 
not needed for these commodities.
    b. Sorghum. The tolerance for linuron residues on sorghum grain 
should remain at 0.25 ppm rather than be lowered to 0.2 ppm as proposed 
in the RED. Field studies show that residues are close to the current 
tolerance level of 0.25 ppm.
    c. Wheat, hay, and corn, sweet, fodder. In the RED, the Agency 
stated that the linuron tolerances for wheat, hay, and corn, sweet, 
fodder, should be revoked, since these commodities were no longer raw 
agricultural commodities. However, these commodities are listed as RACs 
in updated versions of Table II of Subdivision O of the Pesticide 
Assessment Guidelines. Consequently, the Agency will not propose to 
revoke the associated tolerances since these tolerances are needed.
    5. Reassessment of tolerances for uses with outstanding data 
requirements. In the RED, the Agency has required additional studies to 
support reassessment of tolerances for: corn, field, grain; corn, 
field, fodder; corn, field, forage; corn, sweet (K + CWHR); corn, 
sweet, forage; sorghum, fodder; sorghum, forage; soybeans, forage; 
soybeans, hay; and wheat, forage. EPA will reassess these tolerances 
once the required data have been submitted and reviewed. Two 
registrants for the cotton use have requested voluntary cancellation of 
this use, but other registrants may support the use. If the use is 
supported, the Agency will require a processing study to support 
reassessment of the tolerance for cottonseed; if the use is not 
supported, the Agency will propose to revoke the cottonseed tolerance. 
In addition, data to support establishing a tolerance for aspirated 
grain fractions for field corn are outstanding; and data are needed to 
support tolerances for corn, sweet, stover and wheat, hay.
    6. Revising commodity definitions. Current linuron tolerances 
include commodity terminology, Crop Group designations, or definitions 
that are not in accordance with the revised Crop Group Regulation (40 
CFR part 180, 60 FR 26625, May 17, 1995) or with Table II of 
Subdivision O of the Pesticide Assessment Guidelines. Most of these 
changes are slight, and not likely to result in any confusion; the 
exception is corn fodder, which has been changed to corn stover for 
both field and sweet corn. The amendments at the end of this notice 
show all changes in commodity terminology.

IV. Regulatory Assessment Requirements

A. Executive Order 12866

    Under Executive Order 12866 (58 FR 51735, October 4, 1993), the 
Agency must determine whether the regulatory action is ``significant'' 
and therefore subject to review by the Office of Management and Budget 
(OMB) and the requirements of the Executive Order. Under section 3(f), 
the order defines a ``significant regulatory action'' as an action that 
is likely to result in a rule: (1) having an annual effect on the 
economy of $100 million or more, or adversely and materially affecting 
a sector of the economy, productivity, competition, jobs, the 
environment, public health or safety, or State, local or tribal 
governments or communities (also referred to as ``economically 
significant''); (2) creating serious inconsistency or otherwise 
interfering with an action taken or planned by another agency; (3) 
materially altering the budgetary impacts of entitlements, grants, user 
fees, or loan programs or the rights and obligations of recipients 
thereof; or (4) raising novel legal or policy issues arising out of 
legal mandates, the President's priorities, or the principles set forth 
in this Executive Order. Pursuant to the terms of this Executive Order, 
it has been determined that this rule is not a ``significant regulatory 
action,'' because it does not meet any of the regulatory-significance 
criteria listed above.

B. Regulatory Flexibility Act

    This proposed rule has been reviewed under the Regulatory 
Flexibility Act of 1980 [Pub. L. 96-354; 94 Stat. 1164, 5 U.S.C. 601 et 
seq.] and EPA has determined that it will not have a significant 
economic impact on a substantial number of small businesses, small 
governments, or small organizations.
    Accordingly, I certify that this proposed rule does not require a 
separate regulatory flexibility analysis under the Regulatory 
Flexibility Act.

C. Paperwork Reduction Act

    This proposed regulatory action does not contain any information 
collection requirements subject to review by OMB under the Paperwork 
Reduction Act of 1980, 44 U.S.C. 3501 et seq.

D. Unfunded Mandates Reform Act

    This action does not impose any enforceable duty, or contain any 
``unfunded mandates'' as described in Title II of the Unfunded Mandates 
Reform Act of 1995 (Pub. L. 104-4), or require prior consultation as 
specified by Executive Order 12875 (58 FR 58093, October 28, 1993), 
entitled Enhancing the Intergovernmental Partnership, or special 
consideration as required by Executive Order 12898 (59 FR 7629, 
February 16, 1994).

Performance-Oriented Packaging Standards; Final Transitional 
Provisions

AGENCY: Research and Special Programs Administration (RSPA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: RSPA is proposing to incorporate into the Department's 
Hazardous Materials Regulations (HMR) a number of changes, based on 
agency initiative, petitions for rulemaking and comments received at 
public meetings, to the classification of certain hazardous materials 
which are poisonous by inhalation and to provisions for the 
manufacture, use and reuse of hazardous materials packagings. The 
intended effect of these regulatory changes is to improve safety, 
reduce costs to offerors and transporters of hazardous materials, make 
the regulations easier to use and correct errors.

DATES: Comments must be received on or before August 2, 1996.

ADDRESSES: Address comments to Dockets Unit (DHM-30), Hazardous 
Materials Safety, RSPA, U.S. Department of Transportation, Washington, 
DC 20590-0001. Comments should identify the docket and notice number 
and be submitted, when possible, in five copies. Persons wishing to 
receive confirmation of receipt of their comments should include a 
self-addressed, stamped postcard. The Dockets Unit is located in Room 
8421 of the Nassif Building, 400 Seventh Street SW., Washington, DC 
20590-0001. Office hours are 8:30 am to 5:00 pm Monday through Friday, 
except on public holidays when the office is closed.

FOR FURTHER INFORMATION CONTACT: Beth Romo, telephone (202) 366-8553, 
Office of Hazardous Materials Standards, or Bill Gramer, telephone 
(202) 366-4545, Office of Hazardous Materials Technology, Research and 
Special Programs Administration, Washington DC, 20590-0001.

SUPPLEMENTARY INFORMATION:

I. Background

    On December 21, 1990, RSPA published a final rule [Docket HM-181; 
55 FR 52402], which comprehensively revised the HMR with respect to 
hazard communication, classification, and packaging requirements based 
on the United Nations (UN) Recommendations on the Transport of 
Dangerous Goods. A document responding to petitions for reconsideration 
and containing editorial and substantive revisions to the final rule 
was published on December 20, 1991 [56 FR 66124]. On October 1, 1992, 
under Dockets HM-181 and HM-189, RSPA issued editorial and technical 
corrections to the regulations published in 1991. On September 24, 
1993, RSPA issued a final rule under Docket HM-181F [58 FR 50224] which 
made changes to the HMR based on agency initiative and petitions for 
rulemaking received since the December 20, 1991 response to petitions 
for reconsideration. That final rule primarily revised requirements 
with a mandatory compliance date of October 1, 1993, as provided in the 
transitional provisions in Sec. 171.14(b)(4).
    This rule, as proposed, addresses most remaining issues associated 
with the implementation of Docket HM-181 provisions and certain other 
issues arising from a final rule issued December 29, 1994, under Docket 
HM-215A [59 FR 67390]. Many of these proposed changes are to 
requirements with a compliance date of October 1, 1996. These issues 
have been raised through petitions for rulemaking and agency 
initiative. Although these proposed changes focus primarily on 
provisions concerning hazard classification and the maintenance and use 
of performance packaging, RSPA also is proposing changes to 
intermediate bulk container (IBC) requirements, portable tank 
requirements, and regulated medical waste provisions adopted under 
Dockets HM-181E and HM-181G, respectively. Several current exemptions 
would be converted into regulations of general applicability, and an 
approval concerning design qualification and periodic testing would be 
incorporated into the HMR.
    This proposed rule does not address the manufacture, maintenance 
and use of fiber drums. A final rule was published February 29, 1996 
[61 FR 7958] which extends the authority to ship certain liquid 
hazardous materials in open-head fiber drums that do not meet 
performance-oriented packaging standards for hazardous materials in 
Packing Group III.
    This proposed rule is consistent with the goals of President 
Clinton's Regulatory Reinvention Initiative. The President directed 
Federal agencies to review all agency regulations and eliminate or 
revise those that are outdated or in need of reform. A notice issued 
April 4, 1995 by RSPA requested comments on regulatory reform (Docket 
HM-222; 60 FR 17049) and announced a comprehensive review of the HMR to 
identify provisions that are candidates for elimination, revision, 
clarification, or relaxation. Certain proposed changes in this document 
reflect the results of this review.

II. Summary of Proposed Regulatory Changes by Section

    Listed below is a section-by-section summary of the proposed 
changes and, where applicable, the assigned petition number.

Part 171

    Section 171.7. The table of material incorporated by reference 
would be amended by adding a new entry referencing a publication issued 
by the Department of Health and Human Services for defining biosafety 
levels.
    Section 171.14. All transitional provisions reflecting a compliance 
date of October 1, 1996, or earlier would be removed. Three remaining 
transition provisions apply to packages filled prior to October 1, 
1991, new placard specifications, and authorization for use of fiber 
drums.

Part 172

    Section 172.101. The text preceding the Sec. 172.101 Hazardous 
Materials Table (HMT) sets forth procedures for using the HMT. RSPA 
received a petition for rulemaking [P-1169] from the Hazardous 
Materials Advisory Council (HMAC) requesting clarification of the 
procedures contained in paragraph (c)(12)(iii) for selecting a proper 
shipping name for a material that meets the definition of more than one 
hazard class. RSPA agrees and is proposing to replace the phrase 
``identify . . . by a specific description'' with ``identify . . . 
specifically by name'' and include an example.
    Section 172.101; the Hazardous Materials Table (HMT). A new entry 
to provide for the domestic transportation of black powder for small 
arms reclassed as a Division 4.1 would be added. This proposed revision 
is in response to a petition [P-1295] asking RSPA to incorporate the 
provisions of an exemption (DOT-E-8958) into regulations of general 
applicability. As part of the justification for the request, the 
petitioner noted an incident-free shipping history of more than 12 
years and cited comparable provisions for smokeless powder, small arms 
cartridges and power device cartridges. In conjunction with this 
proposed

[[Page 33217]]

change, a new Special Provision 70 and new non-bulk packaging section 
Sec. 173.170 would be added.
    In the HMT, the entries ``Chlorosilanes, n.o.s.'', with 
identification numbers UN 2986, UN 2987, and UN 2988, are not 
authorized to be shipped in IM portable tanks. A petitioner [P-1257] 
requested that RSPA authorize IM portable tanks for all chlorosilanes 
because individual chlorosilanes, such as Ethyldichlorosilane, 
Methyldichlorosilane and Trichlorosilane, pose similar hazards and are 
authorized under the HMR to be shipped in IM portable tanks. RSPA 
agrees with the petitioner that authorizing certain IM portable tanks 
for all chlorosilanes would not compromise safety and would be 
consistent with packaging authorizations for other materials posing 
similar hazards. RSPA proposes to add special provisions in Column (7) 
for ``Chlorosilanes, n.o.s.'', with identification numbers UN 2986, UN 
2987, and UN 2988, to permit the transport of these materials in IM 
portable tanks.
    Bulk packaging references for three Type F organic peroxides (UN 
3110, UN 3119, and UN 3120) would be revised by changing ``None'' to 
``225'' in Column (8C) to indicate that these materials are authorized 
in bulk packagings. In addition, for the entries ``Organic Peroxide, 
type F, liquid (or solid), temperature controlled'' (UN 3119 and UN 
3120), in Column (8A), the packaging exception reference ``152'' would 
be removed for each entry to indicate that these temperature controlled 
organic peroxides are not eligible for packaging exceptions.
    Twenty-nine entries classed as Division 4.3 (dangerous when wet) 
solids in Packing Groups II and III would be amended by revising Column 
(8A) to authorize Sec. 173.151 as a packaging exception section.
    Revisions to Classification and Hazard Zone Identification for 
Certain Materials Poisonous by Inhalation. Based on acute inhalation 
toxicity data and related information obtained by RSPA, the HMT would 
be amended to change the hazard zone for some materials poisonous by 
inhalation, and to add other materials to the list of materials 
poisonous by inhalation. For certain materials this revision would 
impose more stringent hazard communication and packaging requirements. 
The materials and a description of the data on which these proposals 
are based are listed as follows:
    a. Bromine trifluoride (UN1746). This material is a liquid at 
20 deg.C and is identified as a Hazard Zone B inhalation hazard. Based 
on harmonization of the HMR with the UN Recommendations (Eighth revised 
edition), bromine trifluoride is assigned to Division 5.1. However, 
according to Sec. 173.2a(a), ``Division 6.1 (poisonous liquids), 
Packing Group I, poisonous-by-inhalation only'' takes precedence over 
``Division 5.1 (oxidizers).'' Therefore, RSPA is proposing to add the 
plus (+) symbol to Column 1 of the entry for bromine trifluoride.
    b. Hydrogen cyanide, solution in alcohol (with not more than 45 
percent hydrogen cyanide) (UN3294). This material is a liquid at 
20 deg.C and is classified as a Division 6.1 material. Packing Group I 
only is assigned. Hydrogen cyanide, stabilized (UN1051), is identified 
as a Hazard Zone A inhalation hazard. Therefore, based on the toxicity 
and volatility of hydrogen cyanide, the packing group assigned and the 
dilution factor for this solution of hydrogen cyanide, RSPA is 
proposing to identify hydrogen cyanide, solution in alcohol with not 
more than 45 percent hydrogen cyanide as a Hazard Zone B inhalation 
hazard.
    c. Metal carbonyls, n.o.s. (UN3281). This generic entry covers 
Division 6.1, Packing Group I, II and III toxic metal carbonyls that 
are not specifically listed by name but which exhibit acute oral, 
dermal and/or inhalation toxicity. The acute toxicity of these metal 
carbonyls may differ from one compound to another. Those toxic by 
inhalation may fall into Hazard Zone A or Hazard Zone B. Others may not 
be toxic by inhalation, but may exhibit oral and/or dermal toxicity, 
which places them in Division 6.1, Packing Group I. Therefore, RSPA is 
proposing to add special provision ``5'' to Column 7 of the entry for 
metal carbonyls, n.o.s. at the Packing Group I level.
    d. Methanesulfonyl chloride (UN3246). This material is a liquid at 
20 deg.C and is classified as a Division 6.1 material. Acute inhalation 
toxicity data for this material was obtained from a Special Approval 
application before the material was listed by name in the UN 
Recommendations (Seventh revised edition) and, subsequently, in the 
HMR. Following publication of the final rule under Docket HM-215A (59 
FR 67390; December 29, 1994), a manufacturer submitted data identifying 
the material as a Hazard Zone B inhalation hazard (rat; LC50:205 ppm/1H 
(hour); V (saturated vapor concentration):2760 ppm). RSPA agrees with 
the data and is proposing to identify methanesulfonyl chloride as a 
Hazard Zone B inhalation hazard.
    e. Methyl vinyl ketone (UN1251). This material is a liquid at 
20 deg.C and is classified as a Class 3 material. Acute inhalation 
toxicity data for methyl vinyl ketone was listed in the Registry of 
Toxic Effects of Chemical Substances (RTECS) (RTECS: EM9800000), as 
follows: Rat; LC50:7 mg/m\3\/4H. The value, converted to ppm/one hour, 
was: Rat; LC50:5 ppm/1H. The saturated vapor concentration was 
calculated to be: V:93400 ppm at 20 deg.C, indicating that methyl vinyl 
ketone is a material poisonous by inhalation and falls within Hazard 
Zone A. RSPA agrees with this data and is proposing to identify methyl 
vinyl ketone as a Hazard Zone A inhalation hazard. Also, to maintain 
harmony with the UN Recommendations (Eighth revised edition), RSPA is 
proposing to add the plus (+) symbol to Column 1 of the entry for 
methyl vinyl ketone.
    f. Nitriles, toxic, flammable, n.o.s. (UN3275). This generic entry 
covers Division 6.1, Packing Group I and II toxic, flammable nitriles 
that are not specifically listed by name but exhibit acute oral, dermal 
and/or inhalation toxicity. The acute toxicity of these nitriles may 
differ from one compound to another. Those toxic by inhalation may fall 
into Hazard Zone A or Hazard Zone B. Other nitriles may not be toxic by 
inhalation, but may exhibit oral and/or dermal toxicity which places 
them in Division 6.1, Packing Group I. Therefore, RSPA is proposing to 
add special provision ``5'' to Column 7 of the entry for nitriles, 
toxic, flammable, n.o.s. at the Packing Group I level.
    g. Nitriles, toxic, n.o.s. (UN3276). This generic entry covers 
Division 6.1, Packing Group I, II and III toxic nitriles that are not 
specifically listed by name but exhibit acute oral, dermal and/or 
inhalation toxicity. The acute toxicity of these nitriles may differ 
from one compound to another. Those toxic by inhalation may fall into 
Hazard Zone A or Hazard Zone B. Other nitriles may not be toxic by 
inhalation, but may exhibit oral and/or dermal toxicity which places 
them in Division 6.1, Packing Group I. Therefore, RSPA is proposing to 
add special provision ``5'' to Column 7 of the entry for nitriles, 
toxic, n.o.s. at the Packing Group I level.
    h. Organoarsenic compound, n.o.s. (UN3280). This generic entry 
covers Division 6.1, Packing Group I, II and III toxic organoarsenic 
compounds that are not specifically listed by name but exhibit acute 
oral, dermal and/or inhalation toxicity. The acute toxicity of these 
organoarsenic compounds may differ from one compound to another. Those 
toxic by inhalation may fall into Hazard Zone A or Hazard Zone B. 
Others may not be toxic by inhalation, but may exhibit oral and/or 
dermal

[[Page 33218]]

toxicity which places them in Division 6.1, Packing Group I. Therefore, 
RSPA is proposing to add special provision ``5'' to Column 7 of the 
entry for organoarsenic compound, n.o.s. at the Packing Group I level.
    i. Organophosphorus compound, toxic, flammable, n.o.s. (UN3279). 
This generic entry covers Division 6.1, Packing Group I and II toxic, 
flammable organophosphorus compounds that are not specifically listed 
by name but may exhibit acute oral, dermal and/or inhalation toxicity. 
The acute toxicity of these organophosphorus compounds may differ from 
one compound to another. Those toxic by inhalation may fall into Hazard 
Zone A or Hazard Zone B. Others may not be toxic by inhalation, but may 
exhibit oral and/or dermal toxicity which places them in Division 6.1, 
Packing Group I. Therefore, RSPA is proposing to add special provision 
``5'' to Column 7 of the entry for organophosphorus compound, toxic, 
flammable, n.o.s. at the Packing Group I level.
    j. Organophosphorus compound, toxic, n.o.s. (UN3278). This generic 
entry covers Division 6.1, Packing Group I, II and III toxic 
organophosphorus compounds that are not listed by name but exhibit 
acute oral, dermal and/or inhalation toxicity. The acute toxicity of 
these organophosphorus compounds may differ from one compound to 
another. Those toxic by inhalation may fall into Hazard Zone A or 
Hazard Zone B. Others may not be toxic by inhalation, but may exhibit 
oral and/or dermal toxicity which places them in Packing Group I. 
Therefore, RSPA is proposing to add special provision ``5'' to Column 7 
of this entry for organophosphorus compound, toxic, n.o.s. at the 
Packing Group I level.
    k. Phosphorus pentafluoride (UN2198). This material is a gas at 
20 deg.C and is currently identified as a Hazard Zone A inhalation 
hazard - a tentative classification since no acute inhalation toxicity 
data was available. The Compressed Gas Association, Inc. (CGA) has 
reviewed the acute inhalation toxicity of phosphorous pentafluoride, 
among others. In their Standard for Classification of Toxic Gas 
Mixtures (CGA P-20--1995), the CGA estimates the toxicity to be: Rat; 
LC50:260 ppm/1H. RSPA agrees with the CGA estimate and is proposing to 
identify phosphorus pentafluoride as a Hazard Zone B inhalation hazard.
    l. Tungsten hexafluoride (UN2196). This material is a gas at 
20 deg.C and is currently identified as a Hazard Zone C inhalation 
hazard. This was an RSPA estimate since no acute inhalation toxicity 
data was available. The CGA has reviewed the acute inhalation toxicity 
of tungsten hexafluoride. In their Standard for Classification of Toxic 
Gas Mixtures, the CGA estimates the toxicity to be: Rat; LC50:217 ppm/
1H. RSPA agrees with the CGA estimate and is proposing to identify 
phosphorus pentafluoride as a Hazard Zone B inhalation hazard.
    Section 172.102. Special Provision B59, which authorizes AAR 207A 
rail cars for phosphorus pentasulfide, would be revised based on a 
petition [P-1286] submitted by the Association of American Railroads 
(AAR). In its petition, the AAR maintained that the current 
authorization in B59 for AAR Specification ``207A tank cars'' is not 
correct. The AAR acknowledged that it has contributed to the problem by 
referring to these cars in its Tank Car Manual as tank cars, when they 
are, in fact, hopper cars used to transport solid materials. RSPA 
agrees that these cars are more appropriately described as hopper cars 
and proposes to amend Special Provision B59 accordingly.
    A new special provision (N42) would be added to authorize a UN 1A1 
steel drum for stabilized benzyl chloride. Prior to the adoption of 
performance packaging standards under Docket HM-181, the use of DOT 
Specification 5A and 17C steel drums was authorized for stabilized 
benzyl chloride. Under Docket HM-181, Special Provision N43 was 
assigned to both stabilized and unstabilized benzyl chloride, which 
prohibited use of metal drums other than those constructed of monel or 
nickel. Based on a petition for rulemaking [P-1296], RSPA agrees with 
the petitioner that certain 1A1 steel drums having a phenolic lining 
are appropriate for stabilized benzyl chloride. Therefore, RSPA is 
proposing to remove N43 from the entry for benzyl chloride and replace 
it with a new special provision N42, which will allow use of phenolic-
lined steel drums with a minimum thickness of 0.050 inches which have 
been tested and certified to a Packing Group I level at a specific 
gravity of 1.8.
    Section 172.302. In the general marking requirements for bulk 
packagings, markings on portable tanks with capacities of less than 
3,785 L (1,000 gallons) must be at least 6.0 mm (0.24 inch) wide and at 
least 25 mm (one inch) high. RSPA received a petition for rulemaking 
[P-1191] requesting that paragraph (b)(2) of this section be amended to 
decrease to 3 mm the minimum width of markings required on portable 
tanks having a capacity less than 3,785 L (1,000 gallons). The 
petitioner stated that the required minimum width (6 mm) is 
disproportionate to the required minimum height (25 mm). The petitioner 
stated that this marking is difficult to read, which reduces the 
effectiveness of the marking. RSPA agrees that the width of the 
markings should be proportionate to the height, but believes that 3 mm 
may be too narrow for the size of the packaging. In this notice, RSPA 
proposes to revise the minimum width of markings for portable tanks 
with capacities less than 3,785 L (1,000 gallons) to 4 mm (0.16 
inches). In addition, minimum height of markings required on IBCs would 
be specified in paragraph (b)(2) as 25 mm (one inch). Currently, 
minimum height markings for IBCs would fall under paragraph (b)(3) with 
IBCs described as ``other bulk packagings'' which are required to have 
a minimum height of 50 mm (2.0 inches). RSPA has received comments 
requesting the minimum height requirement be lowered for IBCs. After 
reviewing this issue, RSPA agrees that the minimum marking height for 
IBCs should be consistent with markings for smaller portable tanks and 
is proposing a reduction in both height and width for IBCs.
    Section 172.504. In response to a petition for rulemaking from HMAC 
[P-1169], RSPA is proposing to remove paragraph (f)(8), which allows a 
CLASS 9 placard to be substituted for a COMBUSTIBLE LIQUID placard for 
a material meeting both Combustible liquid and Class 9 hazard classes. 
HMAC noted the potential for confusion and delay of a shipment because 
of inconsistencies between the documentation and marking requirements 
describing a Combustible liquid and the application of CLASS 9 
placards. In addition, this alternative placarding conflicts with 
paragraph (f)(9), which provides an exception from placarding for Class 
9 materials in domestic transportation.

Part 173

    Section 173.24a. It has come to RSPA's attention that certain 
cushioning materials deteriorate if there is even minimal leakage from 
an inner packaging. A degradation of cushioning materials could 
seriously reduce the effectiveness of a packaging and render it as not 
conforming to its marked performance standard or not meeting general 
packaging requirements. Paragraph (a)(3) would be revised to clarify 
that cushioning material used to protect inner packagings must not be 
adversely affected (e.g., disintegrate) if there is leakage of a 
hazardous material from the inner packagings. This clarification is 
consistent with

[[Page 33219]]

international air transport provisions contained in the International 
Civil Aviation Organization's Technical Instructions.
    Currently, paragraphs (b)(1) and (b)(2) provide filling limits for 
single and composite packagings, but no such limits are provided for 
combination packagings. RSPA proposes to revise paragraph (b)(2) of 
this section to prescribe filling limits for all non-bulk packagings, 
including combination packagings. This provision would prohibit 
combination packagings from being filled with a hazardous material to a 
gross mass greater than the maximum gross mass marked on the packaging.
    In addition, a new paragraph (e) would be added to incorporate a 
definition for stainless steel as it pertains to non-bulk packaging. 
This is consistent with paragraph (b) in Sec. 173.24b for calculating 
equivalent steel for bulk packagings.
    Section 173.28. RSPA received a petition [P-1303] requesting that 
paragraph (b)(4) be revised to incorporate a calculation which may be 
used to determine an equivalent drum thickness for stainless steel 
drums. The petitioner maintained that drums fabricated of stainless 
steel are less susceptible to damage or a reduction in structural 
integrity resulting from mechanical stresses associated with handling 
and reuse. The petitioner further claimed that an equivalent level of 
safety can be achieved through reuse of a thinner stainless steel drum 
and noted the same method is authorized already in the HMR for 
calculating equivalent minimum thicknesses of portable tanks and metal 
IBCs. RSPA agrees, and is proposing to add a formula in paragraph 
(b)(4) for calculating an equivalent minimum thickness for stainless 
steel drums. This proposed formula is consistent with the formula 
contained in Sec. 178.705 for calculating minimum wall thicknesses for 
metal IBCs.
    The Association of Container Reconditioners (ACR) submitted a 
petition for rulemaking [P-1292] dated August 10, 1995, asking RSPA to 
revise the footnote in paragraph (b)(4) once again to reflect a 1.1 mm 
(0.043 inch) head. This footnote has been revised three times since the 
issuance of the 1990 Docket HM-181 final rule. In 1988, ACR (formerly 
National Barrel and Drum Association) was among commenters to the HM-
181 NPRM asking RSPA to allow the ``20/18 gauge'' drum. RSPA responded 
to this comment in the 1990 final rule by adopting a footnote to the 
Sec. 173.28(b)(4) minimum thickness table, to allow the ``20/18 gauge'' 
drum, (i.e. drums of 220 liters with a body thickness of 0.82 mm and 
head thickness of 1.09 mm) to be reused. The 1991 revised final rule 
under Docket HM-181 amended the footnote to allow a minimum body 
thickness of 0.8 mm, with minimum head thickness of 1.1 mm. This change 
was not based on comments or RSPA's intent to change minimum thickness 
requirements, but from revised methods of rounding metric units. In 
1993, the eighth revised edition of the UN Recommendations adopted a 
requirement to mark nominal thickness, which is tied to minimum 
thickness by ISO 3574. RSPA, in response to an ACR request for 
clarification, stated that drums marked in accordance with the UN 
Recommendations would be satisfactory, but they must be marked with the 
minimum thickness to the nearest 0.1 mm. In the 1994 edition of the 
HMR, Footnote 1 continued to authorize a minimum thickness of 0.8 mm 
(0.03 inch) body and 1.1 mm (0.043 inch) head. No changes to the 
footnote were proposed in the Docket HM-215A NPRM published July 18, 
1994, but in its September 6, 1994 comment to this proposed rule, ACR 
``strongly'' urged RSPA to restore Footnote 1 to the original provision 
implemented in the 1990 HM-181 final rule ( 0.82 mm body and 1.09 mm 
head). ACR stated: ``In reprinting this table in 1991, however, the 
thicknesses identified in this footnote were changed, from 0.82 mm 
(0.0324 inch) to `0.8 mm (0.03 inch' in the body and from 1.09 mm 
(0.0428 inch) to `1.1 mm (0.043 inch)' in the heads.'' ACR claimed 
these criteria do not correspond to the 20/18 gauge DOT specification 
drums in current use at the time HM-181 was adopted, ``nor were they 
explained in any fashion in the preamble to the second printing of the 
final rule.'' ACR suggested that the footnote ``could be recast'' to 
prescribe ``0.9 mm nominal (0.82 mm minimum) body and 1.2 mm nominal 
(1.1 mm minimum) body''. In the December 29, 1994 final rule issued 
under HM-215A, RSPA adopted a requirement to mark drums with nominal, 
rather than minimum thickness, based on revised UN Recommendations, but 
retained minimum thickness standards for reuse. In Footnote 1, RSPA 
revised the 0.8 mm thickness to read ``0.80 mm'' for clarity. On 
January 27, 1995, ACR submitted a petition for reconsideration of HM-
215A final rule within the prescribed 30-day period following the 
December 29, 1994 final rule. ACR requested an immediate ``spot'' 
amendment to Footnote 1. In its petition, ACR stated ``. . . we ask you 
to issue an immediate correction to the footnote to Sec. 173.28(b)(4) 
to make it read properly as it did in the December 21, 1990 Federal 
Register: `Metal drums or jerricans constructed with a minimum 
thickness of 0.82 mm (0.032 inch) body and 1.09 mm (0.043 inch) heads 
are authorized.' '' However, on February 24, 1995, after the petition 
for reconsideration period for HM-215A had ended, ACR submitted another 
letter ``intended to provide clarifying detail'' regarding Footnote 1. 
This letter indicated the footnote should be corrected to express 
minimum thicknesses for nominal markings in accordance with the ISO 
standard and should reference a minimum thickness of 0.82 mm body and 
1.11 mm heads, which would bear a nominal marking ``1.2/0.9/1.2.'' Less 
than a month after receipt of the petition requesting an immediate 
correction to authorize 1.09 mm minimum thickness for heads, ACR again 
requested a minimum thickness of 1.11 mm heads. A revised final rule 
under Docket HM-215A issued on May 18, 1995, addressed the ACR petition 
of January 27, 1995, by restoring the minimum thicknesses of 0.82 mm 
body and 1.09 heads, as adopted in the HM-181 final rule issued 
December 21, 1990. ACR responded by submitting a petition for 
rulemaking on August 10, 1995, claiming that RSPA had not adjusted 
Footnote 1 to correlate with ISO Standard 3574:1986, and petitioning 
RSPA to revise Footnote 1 to prescribe a metal drum minimum thickness 
of 0.82 mm body and 1.11 mm heads. ACR indicated that this would result 
in a ``modest increase in the minimum head thickness of 0.02 mm, . . . 
most of the metal thicknesses now set forth in the table . . . also 
involved modest increases.'' In a subsequent action, ACR sent a letter 
to the RSPA Administrator, claiming that ``DOT has been unable to 
successfully marry the international standards used and cited by the UN 
with DOT's minimum thickness requirements, with respect to `20/18' 
style drums.'' ACR also cited ``changes made by RSPA in HM-215A'' (one 
based on the ACR petition for a spot amendment to restore the footnote 
to 0.82 body and 1.09 heads) and noted the agency's failure to adjust 
the Sec. 173.28 footnote to correspond with ISO. Based on this 
discussion, RSPA is proposing one final adjustment to Footnote 1 to 
specify a minimum thickness of 0.82 mm body and 1.11 mm head to 
correspond with ISO and respond to ACR's latest petition.
    Paragraph (b)(7)(iv)(C) would be revised to clarify that there are 
established conditions which must be met before an approval is granted 
by the

[[Page 33220]]

Associate Administrator for Hazardous Materials Safety to allow relief 
from leakproofness testing for a packaging constructed of a material or 
thickness not otherwise authorized in the exception.
    Paragraph (c)(2) prescribes reconditioning requirements for non-
bulk packagings other than metal drums. Based on the merits of a 
request for clarification from the National Association of Chemical 
Distributors, RSPA is proposing that paragraph (c)(2) be revised to 
clarify that repair or replacement of a bung or a removable gasket in a 
plastic closed head (UN 1H1) drum is not considered reconditioning and 
does not subject the drum to reconditioning marking requirements or to 
leakproofness testing requirements if the drum was otherwise excepted 
from leakproofness testing.
    Section 173.32. A final rule issued July 26, 1994, under Docket HM-
181E adopted provisions for intermediate bulk containers and imposed a 
termination date of September 30, 1996 for new construction of DOT 
Specification 56 and 57 portable tanks. As part of that final rule, 
requirements in Part 178 for design, construction and testing of these 
tanks were removed. Although new construction of these tanks will no 
longer be authorized after September 30, 1996, existing DOT 57 tanks 
are authorized for use as long as they are successfully retested in 
accordance with retest provisions of Sec. 173.32(e). Because the 
pressure testing requirements for DOT 57 tanks refer to a section in 
Part 178 which has been removed, RSPA is proposing to reinstate this 
requirement in paragraph (e)(2)(i). In addition, based on the merits of 
a petition [P-1092], RSPA is proposing to amend paragraph (d) to allow 
plastic discharge valves for certain stainless steel DOT 57 tanks 
constructed before October 1, 1996. Allowing a plastic discharge valve 
on these tanks will eliminate the need for an existing exemption, DOT-
E-10916, and will permit continued use of thousands of portable tanks 
with a proven safety record.
    Section 173.115. The Association of American Railroads (AAR), in a 
petition for rulemaking [P-1152], requested a revision to paragraph 
(b)(1) to correct the conversion of 280 kPa to read ``280 kPa (40.6 
psia).'' RSPA agrees and paragraph (b)(1) is revised to reflect the 
correct conversion in parentheses for informational purposes.
    Section 173.120 and Appendix H to Part 173. Based on the merit of 
requests from industry, RSPA is proposing to add provisions to test 
combustible liquids with a flash point above 60.5 deg.C (141 deg.F) and 
below 93 deg.C (200 deg.F) for the ability to sustain combustion. 
Appendix H was added in the Docket HM-215A final rule to incorporate 
additional testing procedures for a material meeting the definition of 
Class 3 (flammable liquid). If this material was unable to sustain 
combustion when heated under test conditions and exposed to an external 
source of flame, it was excepted from the regulations as a Class 3 
material. This notice proposes to expand the exception to apply to 
materials which meet the definition in paragraph (b) for combustible 
liquids. Appendix H to Part 173 would be revised to provide additional 
test temperatures in paragraph 5.(h) for combustible liquids that would 
closely parallel the approach for flammable liquids.
    Sections 173.121, 173.125, and 173.127. Currently, procedures for 
assigning a packing group to a hazardous material in these sections 
convey to the reader that the Sec. 172.101 Table indicates that the 
packing group is to be determined on the basis of the grouping criteria 
for a given hazard class. The AAR and HMAC, in petitions for rulemaking 
[P-1152 and P-1169, respectively], requested that RSPA amend the 
regulatory language in Secs. 173.121(a), 173.125(a), and 173.127(b) to 
mirror the language in Secs. 173.133 and 173.137 for consistency and 
clarity. In this notice, RSPA proposes to clarify the methods for 
determining packing groups described in Secs. 173.121(a), 173.125(a), 
and 173.127(b) for Class 3, Class 4, and Class 5 materials, 
respectively.
    Section 173.133. The introductory text of paragraph (a) sets forth 
procedures for selecting packing group or hazard zone when the 
Sec. 172.101 Table provides more than one packing group and hazard zone 
for a hazardous material. The AAR requested, in a petition for 
rulemaking [P-1152], that RSPA revise the wording ``provides more than 
one packing group and hazard zone'' to read ``provides more than one 
packing and/or hazard zone'' because hazard zones do not apply to 
Packing Group II and III Division 6.1 materials. RSPA agrees and 
proposes to revise the wording ``more than one packing group and hazard 
zone'' to read ``more than one packing group or hazard zone''.
    Section 173.134. Paragraph (a)(4) limits the definition of 
regulated medical waste to exclude discarded cultures and stocks of 
infectious substances. In this proposed rule, paragraph (b) would be 
revised by adding a new paragraph (b)(4) authorizing discarded cultures 
and stocks in Biosafety Levels 1, 2 and 3, as defined in HHS 
Publication No. (CDC) 93-8395, Biosafety in Microbiological and 
Biomedical Laboratories, 3rd Edition, May 1993, Section II to be 
described and packaged as regulated medical waste rather than 
infectious substances. Packagings would be required to conform to 
Packing Group II performance requirements. Transport of these materials 
would be limited to private or contract motor freight carriers in 
dedicated service to the transportation of medical waste.
    Section 173.151. A new paragraph (d) would be added to incorporate 
limited quantity provisions for Division 4.3 (dangerous when wet) solid 
materials in Packing Groups II and III. This proposal would align the 
HMR with limited quantity exceptions contained in the UN 
Recommendations.
    Section 173.156. In the December 21, 1990 final rule under Docket 
HM-181, RSPA imposed a gross weight limit of 30 kg (66 pounds) per 
package on materials shipped under limited quantity and consumer 
commodity provisions to minimize their aggregate risk. RSPA also 
provided an exception in Sec. 173.156 from this 30 kg weight limitation 
for packages of consumer commodities unitized in cages, carts, boxes, 
or similar overpacks when shipped by private or contract carrier or 
common carrier in exclusive use between a manufacturer, a distribution 
center, and a retail outlet. RSPA received a petition for rulemaking 
[P-1213] from the Conference on the Safe Transportation of Hazardous 
Articles (COSTHA) requesting removal of the 30 kg weight restriction 
for ORM-D materials packaged in ``display packs.'' COSTHA described 
these display packs as containing inner receptacles of ORM-D materials 
which are secured in corrugated fiberboard trays and then stacked and 
placed within a strong outer container. Each outer container is 
strapped to a wooden pallet with steel or polyester strapping to form 
an integral part of the packaging. COSTHA claimed the completed package 
meets the general packaging requirements of Subpart B of Part 173 and 
is marked in accordance with Sec. 172.316. As part of its petition, 
COSTHA cited an exemplary safety record in transporting these display 
packs under pre-HM-181 limited quantity provisions, which do not impose 
any weight limitations, but will no longer be authorized after October 
1, 1996.
    RSPA believes that ORM-D materials shipped in the above-described 
display packs achieve an adequate level of safety in transportation. 
Therefore, RSPA proposes to amend Sec. 173.156 by revising paragraph 
(b) to authorize

[[Page 33221]]

ORM-D materials in palletized display packs exceeding the 30 kg (66 
pound) gross weight limitation to be offered for transportation, or 
transported, by highway or rail between a manufacturer, a distribution 
center, and a retail outlet.
    In addition, RSPA is proposing to provide an exception for 
transportation of ORM-D materials to disposal facilities. A petitioner 
[P-1308] requested that RSPA amend paragraph (b) to allow discarded 
consumer commodities to be transported from manufacturing, distribution 
or retail facilities to a disposal facility when packaged in large 
boxes or overpacks exceeding 30 kg (66 pounds). The petitioner claimed 
that the cost of meeting the 30 kg weight limit or packaging these 
consumer commodities in UN-certified performance packagings far exceeds 
any safety benefit achieved. The petitioner also noted that allowing 
distribution centers and retail outlets to ship discarded consumer 
commodities to local disposal facilities rather than back to the 
manufacturer could enhance transportation safety by shortening the 
shipping distance. RSPA agrees and is proposing to amend paragraph (b) 
to authorize discarded consumer commodities to be shipped to disposal 
facilities when packaged in large boxes or similar overpacks exceeding 
30 kg (66 pounds).
    Section 173.158. This section would be revised to authorize 
additional packagings for nitric acid. RSPA received one petition [P-
1280] which pointed out that packaging authorizations for nitric acid 
in 90 percent or greater concentrations, when offered for 
transportation or transported by rail, highway or water, are more 
stringent than packaging authorizations for transportation by cargo 
aircraft only or packaging authorizations for red fuming nitric acid, a 
toxic by inhalation hazard material. RSPA agrees with this petitioner, 
and paragraph (d) would be revised to authorize additional packagings 
for nitric acid in concentrations of 90 percent or greater when offered 
for transportation or transported by rail, highway or water. A 
combination packaging consisting of a 1A2, 1B2, 1D, 1G, 1H2, 3H2 or 4G 
outer packaging with inner glass packagings of 2.5 L (0.66 gallons) or 
less capacity cushioned with a non-reactive, absorbent material and 
packed within a leak-tight packaging of metal or plastic would be 
authorized.
    In addition, RSPA is proposing to revise paragraph (f)(1) based on 
the merits of a petition [P-1289] requesting that 6HH1 and 6HA1 
composite packagings with PFA Teflon inner receptacles be authorized 
for nitric acid concentrations of 70 percent or less. These composite 
packagings are authorized under the provisions of three exemptions and 
have demonstrated an equivalent level of safety
    Section 173.183. Currently under the HMR, Sec. 173.183 authorizes 
nitrocellulose base film to be packaged in combination packagings 
consisting of inner packagings made of metal, strong cardboard, or 
fiberboard, that are packed in certain UN standard packagings. Plastic 
inner packagings are not authorized except under the terms of an 
exemption. A petitioner [P-1130] requested that RSPA amend Sec. 173.183 
to authorize the use of polypropylene inner packagings because 
polypropylene is flame-retardant, produces minimum toxic gases when 
burned, and will not deteriorate film. Because the petitioner has been 
using the packaging under the terms of an exemption and has encountered 
no adverse experience in transportation, RSPA proposes to amend 
Sec. 173.183 by adding a packaging authorization to allow the use of 
polypropylene inner packagings for nitrocellulose base film.
    Section 173.225. Paragraph (a) would be revised to specify that 
inner plastic packagings of a combination packaging used for 
transporting organic peroxides must be constructed of new resin. This 
proposed change is based on a petition for rulemaking [P-1281] 
submitted by the Society of the Plastics Industry for the Organic 
Peroxide Producers Safety Division, which represents major U.S. organic 
peroxide manufacturers. RSPA agrees with the petitioner's claim that 
most regulated organic peroxides are too sensitive to contamination to 
be stored in packages manufactured from ``resin of unknown history.''
    Section 173.306. This section specifies limited quantity provisions 
for compressed gases. In its petition [P-1169], HMAC requested that 
RSPA amend Sec. 173.306 by removing paragraph (i)(1) because it is 
ineffective and does not provide accurate results. In addition, RSPA is 
proposing to revise the introductory text of paragraph (i) to clarify 
that flammability of aerosols is based on obtaining a positive test 
result from any of the three methods contained in this paragraph. This 
approach is consistent with the ICAO Technical Instructions.
    Section 173.314. Prior to issuance of a final rule under Docket HM-
181, the HMR contained summer and winter fill tables that authorized an 
increase in filling densities for liquids and liquefied gases during 
the winter months. In a supplemental notice of proposed rulemaking 
under Docket HM-181C (55 FR 21342), RSPA noted that this filling limit 
provision was ambiguous and did not take into account lading 
temperatures that might be encountered in transit, such as temperature 
extremes in the Northern and Southern regions of the United States. 
Without regard for these broad ranges of temperature, the HMR 
authorized a higher filling limit for certain Class 2 (compressed gas) 
materials in the same tank car during the months of November through 
March (winter) than during the months of April through October 
(summer). Also, for certain products RSPA discovered that the filling 
limit was higher for noninsulated tanks than for insulated tanks during 
the winter season. Based on these inconsistencies and comments received 
to the Docket HM-181C NPRM, RSPA removed the winter filling limit 
criteria for tank cars in the Docket HM-181 final rule published 
December 21, 1990. When transitional provisions for the maintenance and 
use of current packagings end on October 1, 1996, the regulations will 
require for hazardous materials (other than those meeting the criteria 
for materials poisonous by inhalation) a 1.0% outage (or 99.0% filling 
limit) at 41 deg. C (105 deg. F) for insulated tanks and 46 deg. C 
(115 deg. F) for noninsulated tanks, throughout the year. Unless 
otherwise specified in the HMR, materials poisonous by inhalation 
require a 5.0% outage (or 95% filling limit) at 41 deg. C (105 deg. F) 
for insulated tanks and 46 deg. C (115 deg. F) for noninsulated tanks.
    In a letter dated May 24,1996, the American Petroleum Institute 
(API) petitioned RSPA to amend the filling limit regulations to account 
for lower air temperatures during the winter months. The basis for 
API's letter was its further review of safety and economic impacts of 
the final rule on its member companies. As stated in API's letter, 
``the industry calculates that the amount of product loaded will be 
reduced by 3.9 percent from the amount of product now loaded using the 
Winter Fill tables. In the case of uninsulated tank cars, there is a 
4.8 percent reduction. * * *'' As part of its petition, API referenced 
a Phillips Petroleum report, Maximum Calculated Liquid Temperatures for 
Tank Cars in Anhydrous Ammonia and LP Gas Service for 14 Summer and 23 
Winter Locations in the United States for the Years 1933 through 1957, 
that empirically calculated the maximum liquid temperature in a tank 
under extreme temperature conditions. This report concludes that for 
liquefied petroleum gas, the maximum temperature of the liquid in 
transit would reach 83 deg. F in an insulated tank car and 100.6 deg. F 
for a noninsulated tank

[[Page 33222]]

car in the winter months. The temperatures indicated in the Phillips 
Petroleum report are for the years 1933 through 1957.
    The Phillips Petroleum report confirms RSPA's earlier findings that 
the filling limit requirement did not take into account the maximum 
lading temperatures that might be encountered in transit; i.e, the 
temperature maximum for a noninsulated tank car loaded in the winter 
season was recorded at 100.6 deg. F, but the pre-HM-181 regulations 
assumed a temperature maximum of 32 deg. C (90 deg. F). The Phillips 
Petroleum report also indicates a number of data points within the 
range of 90 deg. F to 100 deg. F during the winter season. This data 
confirms that the pre-HM-181 filling limit for noninsulated tanks 
loaded in the winter months did not allow sufficient outage for gas 
expansion.
    In its letter, API petitioned for a reference temperature of 
80 deg. F for insulated tanks, 87 deg. F for certain thermally 
protected and jacketed tanks, and 90 deg. F for noninsulated tanks. If 
adopted, API stated that its proposed reference temperatures for the 
winter months would align the filling limit requirement for tank cars 
with the regulations in effect prior to Docket HM-181. The filling 
limit reference temperature used by API for thermally protected and 
jacketed tanks is based on RSPA's provisions adopted recently under 
Docket HM-216. In the Docket HM-216 final rule, RSPA authorized a new 
reference temperature for certain tank cars having a thermal protection 
material (see Secs. 173.24b and 173.314(c) Note 2) that reduces heat 
transfer into the tank. (See 61 FR 28665)
    The following Table I compares API's proposal and the post-HM-181 
fill limit requirement. The filling limit reference temperatures of 
46 deg. C (115 deg. F) and 41 deg. C (105 deg. F) in Sec. 173.24b are 
adjusted to 15.5 deg. C (60 deg. F) for liquefied petroleum gas to 
correspond to pre-HM-181 regulations and to aid in the comparison 
between the old and the new requirements.

------------------------------------------------------------------------

    Note: The American Society for Testing Materials' Table-24 
provides an easy correction factor for the conversion of a liquid 
volume to 15.5 deg. C (60 deg. F). For liquefied petroleum gas at 
46 deg. C (115 deg. F), the correction factor is 0.904. Multiplying 
the post-HM-181 filling limit of 99.0% (0.990) by the ASTM 
correction factor of 0.904 yields an authorized filling limit of 
89.5% at 15.5 deg. C (60 deg. F), a close approximation to the pre-
HM-181 requirement.

    Although the Phillips Petroleum data supports RSPA's earlier 
findings, the data does suggest that a lower reference temperature than 
the post-HM-181 regulatory minimum may be acceptable during the winter 
months. Based on a review of API's application and the Phillips 
Petroleum report, RSPA is proposing an amendment to the HMR to 
recognize a winter filling reference temperature. However, to account 
for the maximum liquid temperature extremes expected in transit, RSPA 
is proposing winter reference temperatures of 29 deg. C (85 deg. F), 
32 deg. C (90 deg. F), and 38 deg. C (100 deg. F), compared to API's 
request of 84 deg. F, 87 deg. F, and 90 deg. F, for insulated, 
thermally-protected and jacketed, and noninsulated tanks respectively.
    RSPA is soliciting comments on whether the temperature extremes 
shown in the Phillips Petroleum report have changed since 1957 and, if 
so, whether the proposed changes in this NPRM would have an adverse 
impact on transportation safety. Commenters also are encouraged to 
supply transportation data to support or argue against the proposed 
reference temperatures in this NPRM. Such data may be used to increase 
or decrease the proposed reference temperatures.
    Table II shows RSPA's proposed filling limits, adjusted to 
15.5 deg. C (60 deg. F). RSPA's proposal would authorize a filling 
limit less than API's suggestion, but greater than the HM-181 final 
rule for noninsulated tanks loaded in the winter. For insulated and 
thermally-protected and jacketed tanks, the proposed filling limits 
would authorize a filling limit greater than the HM-181 final rule. 
RSPA believes that the proposed filling limits will ensure safety in 
transit while providing economic relief from the requirements adopted 
in the HM-181 final rule.

    In this NPRM, RSPA is proposing to amend the reference temperatures 
used to calculate the required outage for tank car tanks that are 
loaded during the winter (November through March). No changes are 
proposed to the reference temperatures used for other bulk packagings; 
i.e., cargo tanks and portable tanks. This decision is based on the 
Phillips Petroleum report, which considered only tank car tanks. No 
similar information has been submitted on temperature extremes for 
insulated and noninsulated cargo tanks or portable tanks. Commenters 
seeking corresponding changes for other bulk packagings and materials 
should provide RSPA with information and an analysis similar to the 
Phillips Petroleum report.

Part 178

    Section 178.245. RSPA is proposing to make several editorial 
changes for clarity and one significant change to allow DOT 
Specification 51 portable tanks to have openings at locations other 
than the top or one end of the tank under certain circumstances.
    Section 178.245-1. This section would be reorganized for clarity 
and revised to allow DOT Specification 51 portable tanks to have 
openings at locations other than the top or one end of the tank under 
certain circumstances. When originally developed, the DOT Specification 
51 portable tank was principally a skid mounted liquefied petroleum gas 
container. With the advent and acceptance of containerization as a 
means of shipping bulk quantities of compressed gases, RSPA has issued 
numerous exemptions which authorize the transportation in commerce of 
portable tanks which fully conform to the requirements of DOT 
Specification 51 except for the location of filling and discharge 
openings. These tanks generally must be enclosed in an ISO frame and 
fitted with bottom or side filling and discharge openings. Based upon 
the successful operating experience of these tanks under exemption, 
RSPA believes that the HMR

[[Page 33223]]

should be revised to authorize portable tanks with this type of loading 
and discharge configuration. Additionally, one petitioner [P-1108] 
requested that paragraph (b) be amended to permit openings on the sides 
or bottom of these portable tanks. The petitioner stated that 
authorizing side or bottom mounted valves and openings on DOT 
Specification 51 portable tanks is consistent with the IMDG Code and 
would improve the competitiveness of U.S. manufacturers of these tanks 
in the European market. The petitioner asserted that the side or bottom 
mounted valves would be protected to a degree equal or greater than top 
mounted valves. By adopting this proposed change, numerous exemptions 
will no longer be required.
    Section 178.245-4. RSPA is proposing to add a new paragraph (e) to 
require that a DOT 51 portable tank in an ISO framework for 
containerized transportation must meet the requirements specified in 49 
CFR Parts 450-453.
    Section 178.245-6. The first sentence of paragraph (a) would be 
revised to require the nameplate to be in close proximity to the ASME 
plate.
    Section 178.270-12. RSPA is proposing to amend paragraph (a) to 
assure that manufacturers, owners and approval agencies are aware of 
the requirements for the number and type of closures required for 
filling and discharge connections located below the normal liquid level 
of DOT Specification Intermodal (IM) portable tanks. In a review of the 
regulations concerning IM portable tanks, RSPA discovered a discrepancy 
in the regulations. While Sec. 173.32c(g) clearly informs shippers of 
the requirements for the number and type of closures required for 
filling and discharge connections located below the normal liquid level 
of the tank, there is no corresponding requirement in the design 
requirements for the manufacture of IM portable tanks.
    Section 178.601. Paragraph (g)(8) would be added, based on an 
approval issued to the Steel Shipping Container Institute, to list 
changes in one or more design elements which would constitute a 
different drum design type. If one or more of these changes is made to 
a carbon steel drum having a capacity greater than 50 liters, the drum 
manufacturer must perform design qualification testing and periodic 
retesting in accordance with Subpart M of Part 178.
    Section 178.705. Paragraph (c)(2) of this section specifies 
pressure relief devices for metal IBCs. RSPA received a petition [P-
1271] from a manufacturer of fusible vents stating that since fusible 
vents do not open at room temperature, start-to-discharge pressure 
requirements in Sec. 178.702(c)(2) appear to prohibit fusible venting. 
In response to this petition, RSPA is proposing to add a new sentence 
in paragraph (c)(2)(ii) to clarify that the specified start-to-
discharge pressure does not apply to fusible links unless these links 
are the sole source of pressure relief for the IBC. In addition, a 
correction would be made to the constant in the equivalence thickness 
formula for U.S. Standard Units in paragraph (c)(1)(iv)(B) to ensure 
that the resulting thickness is in inches.

III. Rulemaking Analyses and Notices

A. Executive Order 12866 and DOT Regulatory Policies and Procedures

    This proposed rule is not considered a significant regulatory 
action under section 3(f) of Executive Order 12866 and therefore, was 
not reviewed by the Office of Management and Budget. The rule is not 
considered a significant rule under the Regulatory Policies and 
Procedures of the Department of Transportation [44 FR 11034].
    The economic impact of this proposed rule is expected to result in 
only minimal costs to certain persons subject to the HMR and may result 
in modest cost savings to a small number of persons subject to the HMR 
and to the agency. Because of the minimal economic impact of this rule, 
preparation of a regulatory impact analysis or a regulatory evaluation 
is not warranted. This certification may be revised as a result of 
public comment.

B. Executive Order 12612

    This proposed rule has been analyzed in accordance with the 
principles and criteria contained in Executive Order 12612 
(``Federalism''). Federal law expressly preempts State, local, and 
Indian tribe requirements applicable to the transportation of hazardous 
material that cover certain subjects and are not substantively the same 
as Federal requirements. 49 U.S.C. 5125(b)(1). These subjects are:
    (1) The designation, description, and classification of hazardous 
material;
    (2) The packing, repacking, handling, labeling, marking, and 
placarding of hazardous material;
    (3) The preparation, execution, and use of shipping documents 
pertaining to hazardous material, and requirements respecting the 
number, content, and placement of such documents;
    (4) The written notification, recording, and reporting of the 
unintentional release in transportation of hazardous material; or
    (5) The design, manufacturing, fabrication, marking, maintenance, 
reconditioning, repairing, or testing of a package or container which 
is represented, marked, certified, or sold as qualified for use in the 
transportation of hazardous material.
    If adopted as final, this rule would preempt State, local, or 
Indian tribe requirements concerning these subjects unless the non-
Federal requirements are ``substantively the same'' (see 49 CFR 
107.202(d) as the Federal requirements.
    Federal law (49 U.S.C. 5125(b)(2)) provides that if DOT issues a 
regulation concerning any of the covered subjects, after November 16, 
1990, DOT must determine and publish in the Federal Register the 
effective date of Federal preemption. The effective date may not be 
earlier than the 90th day following the date of issuance of the final 
rule and not later than two years after the date of issuance. RSPA 
requests comments on what the effective date of Federal preemption 
should be for the requirements in this proposed rule that concern 
covered subjects.

C. Regulatory Flexibility Act

    This proposed rule would respond to petitions for rulemaking. It is 
intended to provide clarification of the regulations and relax certain 
requirements. Therefore, I certify that this proposal will not, if 
promulgated, have a significant economic impact on a substantial number 
of small entities. This certification is subject to modification as a 
result of a review of comments received in response to this proposal.

D. Paperwork Reduction Act

    There are no new information collection requirements in this 
proposed rule.

E. Regulation Identifier Number (RIN)

    A regulation identifier number (RIN) is assigned to each regulatory 
action listed in the Unified Agenda of Federal Regulations. The 
Regulatory Information Service Center publishes the Unified Agenda in 
April and October of each year. The RIN number contained in the heading 
of this document can be used to cross-reference this action with the 
Unified Agenda.

    Authority: 49 U.S.C. 5101-5127; 49 CFR 1.53.

    5. In Sec. 172.101, a new paragraph (c)(10)(iii) would be added to 
read as follows:

Sec. 172.101   Purpose and use of hazardous materials table.

    (c) * * *
    (10) * * *
    (iii) A mixture or solution not identified in the Table by a 
specific description, comprised of two or more hazardous materials in 
the same hazard class, shall be described using an appropriate shipping 
description (e.g., ``Flammable liquid, n.o.s.''). Some mixtures may be 
more appropriately described according to their application, such as 
``Coating solution'' or ``Extracts, flavoring liquid'' rather than by 
an n.o.s. entry. Under the provisions of subparts C and D of this part, 
the technical names of at least two components most predominately 
contributing to the hazards of the mixture or solution may be required 
in association with the proper shipping name.

``by a specific description,'' would be revised to read ``specifically 
by name (e.g., acetyl chloride),''.
    7. In Sec. 172.101, the Hazardous Materials Table, as amended at 61 
FR 18932, effective October 1, 1996, would be amended by adding in 
alphabetical order or revising the following entries to read as

PART 178--SPECIFICATIONS FOR PACKAGINGS

    36. The authority citation for part 178 would continue to read as 
follows:

    Authority: 49 U.S.C. 5101-5127; 49 CFR 1.53.

    37. Section 178.245-1 would be revised to read as follows:

Sec. 178.245-1   Requirements for design and construction.

    (a) Tanks must be seamless or welded steel construction or 
combination of both and have a water capacity in excess of 1,000 
pounds. Tanks must be designed, constructed, certified and stamped in 
accordance with the ASME Code.
    (b) Tanks must be postweld heat treated and radiographed as 
prescribed in the ASME Code except that each tank constructed in 
accordance with part UHT of the ASME Code must be postweld heat 
treated. Where postweld heat treatment is required, the tank must be 
treated as a unit after completion of all the welds in and/or to the 
shell and heads. The method must be as prescribed in the ASME Code. 
Welded attachments to pads may be made after postweld heat treatment is 
made. A tank used for anhydrous ammonia must be postweld heat treated. 
The postweld heat treatment must be as prescribed in the ASME Code, but 
in no event at less than 1050 deg.F tank metal temperature. 
Additionally, tanks constructed in accordance with part UHT of the ASME 
Code must conform to the following requirements:
    (1) Welding procedure and welder performance tests must be made 
annually in accordance with section IX of the ASME Code. In addition to 
the essential variables named therein the following must be considered 
to be essential variables: Number of passes, thickness of plate, heat 
input per pass, and manufacturer's identification of rod and flux. The 
number of passes, thickness of plate and heat input per pass may not 
vary more than 25 percent from the procedure qualification. Records of 
the qualification must be retained for at least 5 years by the tank 
manufacturer and made available to duly identified representatives of 
the Department of Transportation or the owner of the tank.
    (2) Impact tests must be made on a lot basis. A lot is defined as 
100 tons or less of the same heat and having a thickness variation no 
greater than plus or minus 25 percent. The minimum impact required for 
full-sized specimens shall be 20 foot-pounds (or 10 foot-pounds for 
half-sized specimens) at 0 deg.F Charpy V-Notch in both the 
longitudinal and transverse direction. If the lot test does not pass 
this requirement, individual plates may be accepted if they 
individually meet this impact requirement.
    (c) Except as provided in paragraph (d) of this section, all 
openings in the tank shall be grouped in one location, either at the 
top of the tank or at one end of the tank.
    (d) The following openings may be installed at locations other than 
on the top or end of the tank:
    (1) The openings for liquid level gauging devices, or for safety 
devices, may be installed separately at the other location or in the 
side of the shell;
    (2) One plugged opening of 2-inch National Pipe Thread or less 
provided for maintenance purposes may be located elsewhere;
    (3) An opening of 3-inch National Pipe Size or less may be provided 
at another location, when necessary, to facilitate installation of 
condensing coils; or
    (4) Filling and discharge connections may be installed below the 
normal liquid level of the tank if the tank design conforms to the 
following requirements:
    (i) The tank must be permanently mounted in a full framework for 
containerized transport. For each tank design, a prototype tank, must 
fulfill the requirements of parts 450 through 453 of this title for 
compliance with the requirements of Annex II of the International 
Convention for Safe Containers.
    (ii) Each filling and discharge connection must be equipped with an 
internal self-closing stop-valve capable of closing within 30 seconds 
of actuation. Each internal self-closing stop-valve must be protected 
by a shear section or sacrificial device located outboard of the valve. 
The shear section or sacrificial device must break at no more than 70 
percent of the load that would cause failure of the internal self-
closing stop-valve.
    (iii) Each internal self-closing stop-valve must be provided with 
remote means of automatic closure, both thermal and mechanical. The 
thermal means of automatic closure must actuate at a temperature of not 
over 250 deg.F.
    (e) Each uninsulated tank used for the transportation of compressed 
gas, as defined in Sec. 173.300 of this subchapter, must have an 
exterior surface finish that is significantly reflective, such as a 
light reflecting color if painted, or a bright reflective metal or 
other material if unpainted.
    38. In Sec. 178.245-4, a new paragraph (e) would be added to read 
as follows:

[[Page 33230]]

Sec. 178.245-4   Tank mountings.

* * * * *
    (e) A DOT 51 portable tank that meets the definition of 
``container'' in Sec. 450.3(a)(3) must meet the requirements of parts 
450 through 453 of this title, in addition to the requirements of this 
subchapter.

Sec. 178.245-6   [Amended]

    39. In Sec. 178.245-6, in the first sentence of paragraph (a), the 
wording ``on one of the heads of the tank'' would be revised to read 
``in close proximity to the ASME ``U'' stamp certification''.
    40. In Sec. 178.270-12, in paragraph (a), the first two sentences 
would be revised to read as follows:

Sec. 178.270-12   Valves, nozzles, piping, and gauging devices.

    (a) All tank nozzles, except those provided for filling and 
discharge connections below the normal liquid level of the tank, relief 
devices, thermometer wells, and inspection openings, must be fitted 
with manually operated stop valves located as near the shell as 
practicable either internal or external to the shell. Each filling and 
discharge connection located below the normal liquid level of the tank 
must be equipped with an internal discharge valve. * * *
* * * * *
    41. In Sec. 178.601, the word ``or'' would be removed at the end of 
paragraph (c)(4)(iv), the period at the end of (c)(4)(v) would be 
removed and ``; or'' added in its place and new paragraphs (c)(4)(vi) 
and (g)(8) would be added to read as follows:

    (vi) For a steel drum, variations in design elements which do not 
constitute a different design type under the provisions of paragraph 
(g)(8) of this section.
* * * * *
    (g) * * *
    (8)(i) For a steel drum with a capacity greater than 50 liters 
manufactured from low carbon, cold-rolled sheet steel meeting ASTM 
designations A366/A366M or A568/A568M, a change in any one or more of 
the following design elements constitutes a different drum design type:
    (A) The packaging type and category of the original drum and the 
remanufactured drum, i.e., 1A1 or 1A2;
    (B) The style, (i.e., straight-sided or tapered);
    (C) The rated (marked) capacity and outside dimensions;
    (D) The physical state for which the packaging was originally 
approved (e.g., tested for solids or liquids);
    (E) The marked level of performance of the original drum (i.e., the 
highest packing group, hydrostatic test pressure, or specific gravity 
to which the packaging has been tested);
    (F) Type of side seam welding;
    (G) Steel thicknesses in the head, in the body and in the bottom, 
and type of steel, i.e., stainless or low-carbon;
    (H) End seam type, (e.g., triple or double seam);
    (I) The number of rolling hoops which equal or exceed the diameter 
over the chimes;
    (J) The location, type or size, and material of closures (other 
than the cover of UN 1A2 drums); and
    (K) For UN 1A2 drums:
    (1) Gasket material (e.g., plastic), or properties affecting the 
performance of the gasket;
    (2) Configuration or dimensions of the gasket;
    (3) Closure ring style including bolt size, (e.g., square or round 
back, 0.625'' bolt); and
    (4) Closure ring thickness.
    (ii) Variations in elements other than those listed in paragraph 
(g)(8)(i) of this section are considered minor and do not constitute a 
different drum design type, or ``different packaging'' as defined in 
paragraph (c) of this section for which design qualification testing 
and periodic retesting are required. Minor variations authorized 
without further testing include changes in the identity of the supplier 
of component material made to the same specifications, or the original 
manufacturer of a DOT specification or UN standard drum to be 
remanufactured.
