921.25 SURCHARGES.

   All persons discharging sewage or Industrial Wastes exceeding strengths of Normal Sewage but acceptable for discharge into the POTW shall be subject to a monthly surcharge determined on the basis of the following parameters:

   (a)   "Normal Sewage" means sewage with a daily average of not more than 300 parts per million of suspended solids, and not more than 250 parts per million of BOD, and not more than 20 parts per million of phosphate, and not more than 15 parts per million of ammonia, and not more than 100 ppm of oil and grease.

   (b)   When the total suspended solids (SS), five day biochemical oxygen demand (BOD5), ammonia (NH3), or oil and grease (O&G) exceeds the values of these constituents for Normal Sewage, the excess concentration(s) shall be subject to a surcharge as follows:

      (1)   Pounds of excess suspended solids per day x $0.30 per pound = SS surcharge.

      (2)   Pounds of excess five day biochemical oxygen demand per day x $0.30 per pound = BOD5 surcharge.

      (3)   Pounds of excess ammonia per day x $0.13 per pound = NH3, surcharge.

      (4)   Pounds of excess oil and grease per day x $0.13 per pound = O&G surcharge.

      (5)   Pounds of excess phosphate per day x $0.36 per pound = PO4 surcharge. The flow figure used for calculating the pounds of excess pollutant will be either a metered wastewater flow, a metered water usage, or an agreed upon alternative flow.

   (c)   Any surcharge assessed for excess Pollutants shall be in addition to normal charges and shall not relieve the discharger of liability for Inhibition, Pass Through or damage caused by such discharge.
