(2) Where 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) User's average BOD concentration, in mg/l.

(f) User's average NH3-N concentration, in mg/l.
(g) User's monthly flow to sewage works, in 1,000 gallons.
(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 than 250 mg/l of BOD, 250 mg/l of SS or 25 mg/l of NH3-N.
(C) Each user shall be notified, at least annually, in conjunction with a regular bill of the rate and that portion of the total charge which is attributable to operations and maintenance of the sewage system.
