If it is found that a gas utility has directly or indirectly, by any device whatsoever, demanded, charged, collected or received from any customer a greater or less compensation for any service rendered or to be rendered by such gas utility than that prescribed in the schedules of such gas utility applicable, thereto then filed in the manner provided in Title 58 of the South Carolina Code of Laws or if it is found that any customer has received or accepted any service from a gas utility for a compensation greater or less than that prescribed in such schedules; or if, for any reason, billing error has resulted in a greater or lesser charge than that incurred by the customer for the actual service rendered, then the method of adjustment for such overcharge or undercharge shall be as provided by the following:
1. Fast or Slow Meters. If the overcharge or undercharge is the result of a fast or slow meter, then the method of compensation shall be as follows:a. In case of a disputed account, involving the accuracy of a meter, such meter shall be tested upon request of the customer, as specified in regulation 103-472.b. In the event that the meter so tested is found to have an error in registration of more than two percent, the bill shall be increased or decreased accordingly, if the time at which the error first developed or occurred can be definitely determined. If such time cannot be determined, such correction shall not be made for more than six months.2. Customer Willfully Overcharged. If the gas utility has willfully overcharged any customer, except as provided for in 1 of this rule, then the method of adjustment shall be as stated in the South Carolina Code of Laws Section 34-31-20(A) or such future Code of Laws of South Carolina governing the legal rate of interest of cases of accounts stated and in all cases where any sum or sums of money shall be ascertained and shall draw interest according to law.3. Customer Inadvertently Overcharged. If the gas utility has inadvertently overcharged a customer as a result of a misapplied schedule, an error in reading the meter, a skipped meter reading, or any other human or machine error except as provided in 1 of this rule, the gas utility shall at the customer's option credit or refund the excess amount paid by that customer or credit the amount billed as prescribed by the following: a. If the interval during which the customer was overcharged can be determined, then the gas utility shall credit or refund the excess amount charged during that entire interval, provided that the applicable statute of limitations shall not be exceeded.b. If the interval during which the customer was overcharged cannot be determined then the gas utility shall credit or refund the excess amount charged during the twelve month period preceding the date when the billing error was discovered.c. If the exact usage and/or demand incurred by the customer during the billing periods subject to adjustment cannot be determined then the refund shall be based on an appropriate estimated usage and/or demand.4. Customer Undercharged Due to Wilfully Misleading Company. If the gas utility has undercharged any customer as a result of a fraudulent or wilfully misleading action of that customer, or any such action by any person (other than the employees or agents of the company), such as tampering with, or bypassing the meter when it is evident that such tampering or bypassing occurred during the residency of that customer, or if it is evident that a customer has knowledge of being undercharged without notifying the gas utility as such, then notwithstanding 1 of this rule, the gas utility shall recover the deficient amount provided as follows:a. If the interval during which the customer was undercharged can be determined, then the gas utility shall collect the deficient amount incurred during that entire interval, provided that the applicable statute of limitations is not exceeded.b. If the interval during which the customer was undercharged cannot be determined, then the gas utility shall collect the deficient amount incurred during the twelve-month period preceding the date when the billing error was discovered by the gas utility.c. If the usage and/or demand incurred by the customer during the billing periods subject to adjustment cannot be determined, then the adjustment shall be based on the appropriate estimated usage and/or demand.d. If the metering equipment has been removed or damaged, then the gas utility shall collect the estimated cost of repairing and/or replacing such equipment.5. Equal Payment Plans. A gas utility may provide equal payment plans, wherein the charge for each billing period is the estimated total annual bill divided by the number of billing periods prescribed by the plan. However, any incorrect billing under equal payment plan shall be subject to the first paragraph of this rule.6. Customer Undercharged Due to Human or Machine Error. If the gas utility has undercharged any customer as a result of a misapplied schedule, an error in reading the meter, a skipped meter reading, or any human or machine error, except as provided in 1 and 2 of this rule above, then the gas utility may recover the deficient amount as provided as follows:a. If the interval during which a customer was undercharged can be determined, then the gas utility may collect the deficient amount incurred during that entire interval up to a maximum period of twelve months.b. If the full interval during which a customer was undercharged cannot be determined, then the gas utility may collect only the deficient amount of that portion of the interval that can be determined up to a maximum period of twelve months.c. The customer shall be allowed to pay the deficient amount, in equal installments added to the regular monthly bills, over the same number of billing periods which occurred during the interval the customer was subject to pay the deficient amount.d. If the usage incurred by that customer during the billing periods subject to adjustment cannot be determined, then the adjustment shall be based on an appropriate estimated usage.S.C.
