(A) Adjustment to bill due to meter error. If any service meter shall be found to have a percentage of error greater than allowed, 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 5%, the utility shall credit the customer’s account with the amount in excess of that determined to be an average for ½ the time elapsed since the previous test, or 1 year, whichever is the shorter period. This average charge shall be calculated on the basis of units registered on the meter over the corresponding periods either prior or subsequent to the period for which the meter is determined to be fast. No part of a minimum charge will be credited.
(2) Stopped or slowed meters. When a meter is stopped or has a negative average error (i.e., is slow) in excess of 5%, the utility may charge the customer an amount estimated to be an average charge for ½ the time lapsed since the previous test, or 1 year, whichever is the shorter period. This average shall be calculated on the basis of units registered on the meter over the corresponding periods either prior or subsequent to the period for which the meter is determined to be slowed or stopped. This action may be taken only in cases where the utility is not at fault for allowing the stopped or slowed meter to remain in service.
(B) Other billing adjustments. All other billing errors, including but not limited to incorrect tariff applications, may be adjusted to the known date of error or for a period of 1 year, whichever period is shorter.
