(A) Annual audit. The municipality shall annually review the wastewater contribution of its sewer users, the operation, maintenance, and replacement expenses of the wastewater collection and treatment facilities, and the sewer service charge system in accordance with those procedures established by the State Auditor’s office and federal statutes (40 C.F.R. 35.2140(d)). Based on this review, the municipality shall revise the sewer service charge system, if necessary, to accomplish the following:
(1) Maintain a proportionate distribution of operation, maintenance, and replacement expenses among sewer users based on the wastewater volume and pollutant loadings discharged by the users;
(2) Generate sufficient revenues to pay the operation, maintenance, and replacement expenses of the wastewater collection and treatment facilities; and
(3) Apply excess revenues collected from a class of users to the operation, maintenance, and replacement expenses attributable to that class of users for the next year and adjust the sewer service charge rates accordingly.
(B) Annual notification. The municipality shall notify its sewer users annually about the sewer service charge rates. Notification shall separately indicate what portion of the rates are attributable to the user charge, as defined by this chapter. The notification shall occur in conjunction with a regular bill.
(C) Records. The municipality shall maintain records regarding wastewater flows and loadings, costs of the wastewater collection and treatment facilities, sampling programs, and other information which is necessary to document compliance with 40 C.F.R. 35, Subpart E of the Clean Water Act.
