Exhaust emission retests shall not be conducted unless the owner or operator of the vehicle demonstrates that the vehicle has had appropriate repairs for the reason of failure. In the case of tampering failures, the owner or operator must demonstrate that the tampered condition or equipment has been repaired or replaced before a retest is performed.

(g) If the U.S. EPA has granted a waiver in accordance with Section 182(f) of the Clean Air Act* for any county or counties subject to this rule, the department may determine that during the period when the NOx waiver is in effect, failure of the NOx portion of the I/M test is not grounds for denial of a certificate of compliance for vehicles within that county or counties. Upon making such a determination, the department shall notify the contractor in writing indicating the effective dates of the determination.

Sec. 9. (a) Each motor vehicle subject to the requirements of this rule shall be subjected to a visual tampering inspection at the facility. The motor vehicle shall be inspected for the presence and good operating condition of emission control devices included in the manufacturer's original design. At a minimum, emission control devices subject to inspection shall include the following:

(1) For I/M 93 emission testing:

(A) Catalytic converters.

(B) Fuel filler caps.

(2) For basic I/M emissions testing:

(A) Catalytic converters.

(B) Fuel filler caps.

If any emission control devices are found in a tampered condition, the devices shall be repaired or replaced prior to any initial testing, retesting, or reinspection as provided in section 8(f) of this rule.

(b) Alteration of a vehicle's chassis configuration from a certified to a noncertified configuration is prohibited. In the inspection process, vehicles that have been altered from their original, certified configuration are to be tested in the same manner as other subject vehicles as follows:

(1) Vehicles with engines other than the engine originally installed by the manufacturer or an identical replacement of the engine shall be subject to the inspection standards for the chassis type and model year for all parts that are part of the original or now-applicable certified configuration.

(2) Vehicles in which the engine of one (1) fuel type has been replaced or modified to an engine of a different fuel type that is subject to the I/M program, such as from a diesel engine to a gasoline engine, shall be subject to the following:

(A) The test procedures and standards for the current fuel type.

(B) The requirements in subdivision (1).

(3) Vehicles that are switched to a fuel type for which there is no certified configuration shall be tested according to the most stringent I/M gasoline emission standards established for that vehicle type and model year. Emission control device requirements may be waived if the department determines that the alternatively fueled vehicle configuration would meet the new vehicle standards for the model year without the devices.

(c) Mixing vehicle classes, such as light-duty with heavy-duty, and certification types, such as California with federal, within a single vehicle configuration shall be considered tampering.

(d) All vehicles must comply with 326 IAC 13-2.1.

Affected: IC 13-15; IC 13-17

Sec. 10. (a) A waiver of the requirement that a motor vehicle obtain a certificate of compliance may be issued only under the following conditions:

(1) A waiver shall be issued only after a vehicle has failed a retest performed after all emission-related repairs as described in subdivisions (3) through (5) have been completed. Vehicles that are subject to an emissions recall but have not had recall repairs shall not be eligible for a waiver until the repairs have been made.

(2) Waivers shall not be issued to vehicles for tampering-related repairs. The cost of tampering-related repairs shall not be applicable to the minimum expenditure in subdivision (5). The department may issue exemptions for tampering-related repairs if the motorist can verify that the part in question or one similar to it is no longer available for sale.

(3) Repairs shall be appropriate to the cause of the test failure, and a visual check shall be made at the time of retest to determine if repairs were actually made. Receipts shall be submitted for review at the test site to further verify that qualifying repairs were performed.

(4) Repairs shall be performed at a certified I/M emission repair facility. A certified I/M emission repair facility shall meet the following criteria:

(A) Employ at least one (1) certified I/M emission repair technician as defined in this rule.

(B) For all I/M emission testing, possess the following:

(vi) 2, 3, 4, or 5 gas analyzer.

(vii) Scan tool.

(viii) Digital storage oscilloscope (DSO).

(ix) OBDII scan tool.

The department may suspend, revoke, or deny renewal of a certification of a certified I/M emission repair facility if the facility fails to adhere to program requirements.

(5) In order to qualify for a waiver, repairs shall be performed by a certified I/M emission repair technician who:

(A) is certified and maintains current certification as an ASE L1 (Advanced Engine Performance) technician;

(B) has successfully completed the department approved emission and driveability training program;

(D) is employed at a certified I/M emission repair facility.

The department may suspend, revoke, or deny renewal of a certification of a certified I/M emission repair technician if the technician fails to adhere to program requirements.

(6) Repairs appropriate to the reason for the failure may be performed by nontechnicians, such as owners, to apply toward the waiver limit for model year vehicles 1976 through 1980.

(7) In order to qualify for a minimum expenditure waiver, motorists in Lake County or Porter County shall expend the following amounts in repairs at a certified emissions repair facility:

(A) For 1981 and newer model year vehicles, the following criteria shall be met:

(i) The vehicle must be at least eight (8) model years of age.

(ii) The vehicle must have been driven at least one hundred fifty thousand (150,000) miles.

(iii) The owner or operator of the vehicle must have spent at least four hundred fifty dollars ($450) for repairs at a certified emissions repair facility.

(B) For 1976 through 1980 model year vehicles, at least seventy-five dollars ($75).

(8) Vehicles subject to an enhanced I/M emission test at the cutpoints established in 40 CFR 51.351* may be issued a certificate of compliance without meeting the prescribed emission cutpoints if, after failing a retest, a complete, documented physical and functional diagnosis and inspection performed by the contractor shows no additional emission-related repairs are needed. Any such exemption policy and procedures shall be subject to EPA approval.

(9) After an initial I/M emission test failure, a vehicle may be retested up to four (4) additional times. A vehicle shall not be retested a fifth time until the type of repairs or modifications necessary has been fully evaluated by department and contractor personnel.

(10) Waivers shall be issued only by the test site manager or other employee specifically designated for this purpose.

(11) A waiver shall be valid for not more than one (1) test cycle.

(b) No vehicle in its lifetime shall receive more than one (1) waiver.
