(A) A surcharge will be levied upon all users whose wastes exceed a concentration of 200 milligrams per liter of BOD or 250 milligrams per liter of SS. The surcharge shall be expressed as dollars per pound of each constituent (BOD or SS).
(B) Quarterly the number of pounds of each constituent from each user subject to a surcharge shall be computed as follows:
B.O.D. (pounds) = (Average analysis per quarter in mg/l - 200) x total flow (MG) x 8.34
S.S. (pounds) = (Average analysis per quarter in mg/l - 250) x total flow (MG) x 8.34
Total flow for the quarter shall be either water meter or flow meter readings and shall be expressed in million gallons (MG).
(C) The surcharge shall be the pounds of each constituent per billing period times the unit cost for each constituent.
(D) The unit cost for BOD shall be $0.178 per pound and the unit cost for S.S. shall be $0.164 per pound.
