(A) Liability for surcharge. Each user discharging wastes into the sewerage, in addition to other sewage service charges imposed by this chapter, based on the following minimum strength characteristics to the extent that such wastes are in concentrations greater than:
(1) Biochemical oxygen demand of 250 milligrams per liter;
(2) Chemical oxygen demand of 500 milligrams per liter;
(3) Suspended solids content of 250 milligrams per liter;
(4) Phosphorus content of ten milligrams per liter; and
(5) Ammonia content of ten milligrams per liter.
(Prior Code, Title V, Ch. II, Art. II, § 35)
(B) Computation of surcharge.
(1) The surcharge shall be determined as follows: the excess pounds of BOD or COD phosphorus, and ammonia will each be computed by first multiplying the user’s billing sewage volume measured in units of 100 cubic feet for the current billing period by the factor 0.0062321 and then multiplying this product by the difference between:
(a) The concentrations measured in milligrams per liter of the BOD or COD, suspended solids, phosphorus and ammonia respectively in the user’s sewage; and
(b) The allowed concentrations set out in division (A) above.
(2) The surcharge for each constituent will then be determined by multiplying the excess pounds of each constituent by the appropriate rate of surcharge set out herein. In the event COD measurement is used, as herein before provided, 50% of the excess pounds measured will be used to compute the equivalent BOD charge.
(Prior Code, Title V, Ch. II, Art. II, § 36)
(C) Waste evaluation charges. All users discharging wastes into the system requiring continuing surveillance sampling and waste evaluation shall be subject to a monthly fixed charge to cover the costs of such services in the amount of $90 per discharge point.
(Prior Code, Title V, Ch. II, Art. II, § 37)
(D) Revision of rates of surcharge. Prior to May 1 of each alternate year, commencing in 1994, the Town Manager and an independent certified public accountant employed for that purpose shall submit to the Town Council a comparison of the calculated unit costs for removing BOD, suspended solids, phosphorus and ammonia from the sewage treatment plant influent during the previous calendar year with the unit charges currently in effect in order that the Town Council may determine whether the current rates of surcharge are adequate or should be changed and request legislative enactment of said changes by the Town Council.
