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 250 parts per million of suspended solids, and not more than 200 parts per million of BOD.
(b) When the total suspended solids (SS) or five day biochemical oxygen demand (BOD5) exceeds the values of these constituents for normal sewage, the excess concentration(s) shall be shall be subject to a surcharge as follows:
(1) Total suspended solids: $33.95 per 100 pounds in excess of normal sewage.
(2) Five day biochemical oxygen demand: $40.12 per 100 pounds in excess of normal sewage.
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.
