(A) In the event the Approving Authority excludes a customer from the requirements of § 54.16 and the customer discharges abnormal industrial wastes to the public sanitary sewerage system having an average total suspended solids content in excess of 250 mg/l and/or an average of 5-day BOD in excess of 200 mg/l and/or COD in excess of 400 mg/l, the customer shall pay a surcharge based upon the excess strength of his or her wastes.
(B) The costs of treatment for each pound of BOD and/or suspended solids removed by the treatment works shall be calculated and reviewed by the city at the end of each fiscal year (January). If a discrepancy exists between the actual costs as found by the city and the estimated costs, the Approving Authority may 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 sewer system contain less than 250 mg/l of suspended solids or 200 mg/l BOD.
