(A) (1) The excessive strength surcharge shall be based on the following formula, with the total to be applied to the monthly bill of the affected users:
[A (E-250) + B(F-250) + C(G-25) + D(H-100)] X .00624 X K = Surcharge Payment ($/Mo.)
(2) The formula components are as follows:
A = Surcharge rate for BOD, in $/pound.
B = Surcharge rate for SS, in $/pound.
C = Surcharge rate for NH3-N, in $/pound.
D = Surcharge rate for O&G, in $/pound.
E = User's average BOD concentration, in mg/l.
F = User's average SS concentration, in mg/l.
G = User's average NH
3-N concentration, in mg/l.
H = User's average O&G concentration, in mg/l.
J = User's monthly flow to sewage works, in 100 cubic ft.
(B) No reduction in sewage service charges, fees, or taxes shall be permitted because of the fact that certain wastes discharged to the sewage works contain less concentrations than those established as maximum in this chapter.
(C) Each user shall be notified, at least annually, in conjunction with a regular bill of the surcharge rate and that portion of the total charge which is attributable to operations and maintenance of the sewage system.
