(A) In the event the approving authority excludes a user from the requirements of § 51.111 and the user discharges abnormal industrial wastes to the public sanitary sewerage system having an average TSS in excess of 240 mg/l or an average of five-day BOD in excess of 204 mg/l, or an average of COD in excess of 500 mg/l, the user shall pay a surcharge based upon the excess strength of his or her wastes.
(B) The costs of treatment for each pound of BOD, suspended solids, or grease removed by each treatment works shall be reviewed by the city annually. If a discrepancy exists between the actual costs as found by the city and the estimated costs, the BOW shall increase or decrease the surcharge rates sufficiently to cover only the projected actual costs for the ensuing year.
(C) No reduction in sewerage service charges, fees, or taxes will be permitted because of the fact that certain industrial wastes discharged to the public sanitary sewerage system contain less than 240 mg/l of total suspended solids, or 204 mg/l BOD.
