Affected: IC 8-1-1-3

Sec. 2. Adjustment of Bills. (a) Adjustments Due to Meter Error. If any water meter on which a sewage bill is based shall be found to have a percentage of error greater than two (2) percent, the following provisions for the adjustment of bills shall be observed:

(1) Fast Meters. When a meter is found to have a positive average error, i.e., is fast, in excess of two (2) percent, the company shall refund or credit the customer's account with the amount in excess of that determined to be an average charge for one-half of the time elapsed since the previous test, or one (1) year, whichever period is shorter. This average charge shall be calculated on the basis of units registered on the meter over corresponding periods either prior or subsequent to the period for which the meter is determined to be fast. No part of a minimum service charge need be refunded.

(2) Stopped or Slow Meters. When a meter is stopped or has a negative average error, i.e., is slow, in excess of two (2) percent, the company may charge the customer an amount estimated to be an average charge for one-half of the time elapsed since the previous test or one (1) year, whichever period is shorter. The average charge shall be calculated on the basis of units registered on the meter over corresponding periods either prior or subsequent to the period for which the meter is determined to be slow or stopped. Such action may be taken only in cases where the sewage disposal company is not at fault for allowing the stopped or slow meter to remain in service.

(b) Adjustment for Interruption of Service. In the event the customer's service is interrupted for a reason other than the act of the customer or the condition of customer controlled equipment, and the service remains interrupted for more than two (2) days after being reported or found to be out of order, appropriate adjustments or refunds shall be made to the customer. Each company shall file with the Commission a tariff detailing the method and amount of refund in such cases.

(c) Other Billing Adjustments. All other billing errors, including incorrect tariff applications, may be adjusted to the known date of error or for a period of one year, whichever period is shorter.

(2) solely upon the credit risk of the individual without regard to the collective credit reputation of the area in which he or she lives.

(b) Each new applicant for residential sewage disposal service shall be deemed creditworthy and shall not be required to make a cash deposit as a condition of receiving service if the applicant satisfies the following criteria:

(A) owes no outstanding bills for service rendered within the past four (4) years by any such utility;

(B) during the last twelve (12) consecutive months that the service was provided, did not have more than two (2) bills that were delinquent to any utility or, if service was rendered for a period for less than twelve (12) months, did not have more than one (1) delinquent bill in such period; and

(C) within the last two (2) years did not have a service disconnected by a utility for nonpayment of a bill for services rendered by that utility.

(2) If the applicant has not been a customer of a utility during the previous two (2) years, the applicant shall be deemed creditworthy if any two (2) of the following criteria are met:

(C) The applicant has credit cards, charge accounts, or has been extended credit by a bank or commercial concern unless a credit check shows that the applicant has been in default on any such account more than twice within the last twelve (12) months.

(c) If the applicant fails to establish that he or she is creditworthy under subsection (b), the applicant may be required to make a reasonable cash deposit. Such deposit shall not exceed one-sixth (¹/6) of the estimated annual cost of service to be rendered to the applicant. If a deposit is greater than seventy dollars ($70), the company shall advise the applicant or customer that he or she may pay such deposit in equal installment payments over a period of no less than eight (8) weeks; service shall be connected upon receipt by the company of the first such payment.

(d) If the company requires a cash deposit as a condition of providing service, then it must immediately notify the applicant in writing stating the precise facts upon which it based its decision and provide the applicant with an opportunity to rebut such facts and show other facts demonstrating his or her creditworthiness as provided under subsection (b).

(e) A sewage disposal company may require a present customer to make a reasonable cash deposit when:

(1) the customer has been mailed disconnect notices for two (2) consecutive months;

(2) the customer has been mailed disconnect notices for any three (3) months within the preceding twelve (12) month period; or

(3) the service to the customer has been disconnected within the past four (4) years pursuant to section 4 of this rule.

The amount of such deposit may not exceed an amount equal to one-sixth (¹/6) of the expected annual billings for the customer at the address at which service is rendered. In the event the required deposit is in excess of seventy dollars ($70), the sewage disposal company shall advise the customer that he or she may pay such deposit in equal installment payments over a period of up to eight (8) weeks, except where such deposit is required as a result of a disconnection for nonpayment, in which case full payment of the deposit may be required prior to reconnection.

(f) Requirements for interest upon deposits shall be as follows:

(1) Deposits held more than twelve (12) months shall earn interest from the date of deposit at a rate of six percent (6%) per annum or at such other rate of interest as the commission may prescribe following a public hearing.

(2) The deposit shall not earn interest after the date it is mailed or personally delivered to the customer, or otherwise lawfully disposed.

(5) Each customer shall be provided a written receipt from the company at the time his or her deposit is paid in full or when he or she makes a cash partial payment. The company shall provide a reasonable method by which a customer who is unable to locate his or her receipt may establish that he or she is entitled to a refund of the deposit and payment of interest thereon.

(6) Any deposit made by the applicant, customer, or any other person to the company (less any lawful deductions), or any sum the company is ordered to refund for sewage disposal service, that has remained unclaimed for one (1) year after the company has made diligent efforts to locate the person who made such deposit or the heirs of such person, shall be presumed abandoned and treated in accordance with IC 32-9-1.5-20(c)(10) [IC 32-9 was repealed by P.L.2-2002, SECTION 128, effective July 1, 2002.] .

Sec. 4. (a) A company may disconnect service without request by the customer and without prior notice only:

(1) if a condition dangerous or hazardous to life, physical safety, or property exists;

(2) upon order by any court, the commission, or other duly authorized public authority;

(3) if fraudulent or unauthorized use of sewage disposal service is detected and the company has reasonable grounds to believe the affected customer is responsible for the use; or

In all other instances, a sewage utility, upon providing the customer with proper notice as defined in subsection (d), may disconnect service subject to the other provisions of this article.

(b) Except as otherwise provided in subsection (a), a sewage disposal company shall postpone the disconnection of service for ten (10) days if, prior to the disconnect date specified in the disconnect notice, the customer provides the company with a medical statement from a licensed physician or public health official that states that a disconnection would be a serious and immediate threat to the health or safety of a designated person in the household of the customer. The postponement of disconnection shall be continued for one (1) additional ten (10) day period upon the provision of an additional such medical statement.

(3) if a customer is unable to pay a bill that is unusually large due to prior incorrect reading of the water meter, incorrect application of the rate schedule, incorrect connection or functioning of the water meter, prior estimates where no actual reading was taken for over two (2) months, stopped or slow water meter, or any human or mechanical error of the sewage disposal company, and the customer:

(A) pays a reasonable portion of the bill, not to exceed an amount equal to the customer's average bill for the twelve (12) bills immediately preceding the bill in question;

(B) agrees to pay the remainder at a reasonable rate; and

(C) agrees to pay all undisputed future bills for service as they become due;

(1) Except as otherwise provided in this article, service to any residential customer shall not be disconnected for a violation of any rule or regulation of a sewage disposal company or for the nonpayment of a bill, except after seven (7) days prior written notice to the customer by either:

(A) mailing the notice to the residential customer at the address shown on the records of the utility; or

(B) personal delivery of the notice to the residential customer or a responsible member of his or her household at the address shown on the records of the sewage utility.

No disconnect notice for nonpayment may be rendered prior to the date on which the account becomes delinquent.

(2) The notice must be in language that is clear, concise, and easily understandable to a layperson and shall state the following in separately numbered large type or printed paragraphs:

(A) The date of proposed disconnection.

(B) The specific actual basis and reason for the proposed disconnection.

(C) The telephone number of the sewage disposal company office at which the customer may call during regular business hours in order to question the proposed disconnection or seek information concerning his or her rights.

(D) A reference to the pamphlet or the copy of the rules furnished to the customer under section 6 of this rule for information as to the customer's rights.

(e) Immediately preceding the actual disconnection of service, the employee of the sewage disposal company designated to perform such function shall:

(1) make a reasonable attempt to identify himself or herself to the customer or any other responsible person then upon the premises;

(2) make a record thereof to be maintained for at least thirty (30) days;

(3) have in his or her possession information sufficient to enable him or her to inform the customer or other responsible person of the reason for disconnection, including the amount of any delinquent bill of the customer; and

(4) request from the customer any available verification that the outstanding bill has been satisfied or is currently in dispute pursuant to review under 170 IAC 16-1-5.

Upon the presentation of such credible evidence, service shall not be disconnected. The employee shall not be required to accept payment from the customer or other responsible person in order to prevent the service from being disconnected. The sewage disposal company shall notify its customers under section 6 of this rule of its policy with regard to the acceptance or nonacceptance of payment by such employee and shall uniformly follow such policy without discrimination. When the employee has disconnected the service, he or she shall give to a responsible person at the customer's premises or, if no one is at home, shall leave at a conspicuous place on the premises a notice stating that service has been disconnected and stating the address and telephone number of the company where the customer may arrange to have service reconnected.

(f) A sewage disposal company may charge a reasonable reconnection charge, not to exceed the charge approved by the commission in the company's filed tariffs, to compensate the company for the costs of disconnecting and reconnecting the service. The company shall inform its customers of the reconnection charge under section 6 of this rule. If the company disconnects service in violation of this rule, the service shall immediately be restored at no charge to the customer. The company must reconnect the service to the customer as soon as reasonably possible but at least within five (5) working days after requested if conditions permit, provided, however, that the company shall not be required to reconnect the service until:

(1) the conditions, circumstances, or practices that caused the disconnection have been corrected; and

(2) payment of all delinquent and reconnection charges owed the utility by the customer and any deposit authorized by this article has been made.

Authority: IC 8-1-2-47; IC 8-1-2-69; IC 8-1-2-89

Affected: IC 8-1-1-3; IC 8-1-2-89

Sec. 35. (a) Refunds shall be paid for a period of ten (10) years after the completion date of the main extension to the original depositor in proportion to the respective deposits, unless the original depositor for the main extension forfeited all rights to refunds, except subsequent connector's fees, as provided in section 32(a)(3) of this rule.

(b) However, no refunds shall be required to be made by the utility until the number of customers actually connected to the main extension equals the number of applicants for which an immediate revenue allowance was included in computing the total required deposit for the main extension. The refunds shall be paid annually or more frequently at regular intervals at the discretion of the utility.

(c) Total refunds to any original depositor shall not exceed the amount of the original deposit except in the case of a phased residential real estate development. In this situation the preliminary plat must be submitted to the utility at the time of the first request for a main extension. During the ten (10) year period beginning with the completion date of the first main extension, the amount of any refunds generated in excess of the deposit made on any phase of the development must be applied against the deposit made for any other phase of the development, so long as the total amount of refunds to the original depositor shall not at any time exceed the total amount of his deposits during the period. The utility shall not require any subsequent connector's fee which is in excess of the unrefunded balance of the aggregate of deposits received from all original depositors.

(d) The refund shall be made by mailing the payment to the original depositor's last known address as shown on the books and records of the utility. Any refund distribution which cannot be returned to an original depositor after the refund becomes due and payable must be reported as required by IC 32-9-1-42 [Repealed by P.L.31-1995, SECTION 9, effective July 1, 1996.] .

Sec. 39. (a) A utility may require a special contract when:

(1) the requested main extension is of such length and the prospective business to be developed by it is so meager as to make it doubtful whether the business from the extension would ever pay a fair return on the utility investment involved in such extension;

(2) the prospects are that the patronage and demand will not be of such permanency as to warrant the capital expenditure involved;

(3) there are industrial installations requiring extensive sewer utility investment and where the demand for sewer service is expected to be slight, irregular, or of unknown quantity; or

(4) there are other abnormal or extraordinary circumstances.

(b) The utility and the applicant requesting the extension may enter into a special contract establishing the terms and conditions on which the extension will be made. In the event they are unable to agree on the terms and conditions, the matter, including the contract embodying the terms and conditions, shall be submitted to the commission for a determination.
