(A) In order that the rates and charges may reflect the costs of providing services rendered to users, the town shall base its charges not only on the volume, but also on the strength and character of the stronger-than-normal domestic sewage and wastes which it is required to treat and dispose. The town shall require the user to determine the strength and content of all sewage and wastes discharged, either directly or indirectly, into the sanitary sewerage system, in the manner and by that method as the town may deem practicable in order to determine the proper charge. The user shall furnish a central sampling point available to the town at all times.
(B) Normal domestic sewage and waste strength should not contain BOD in excess of 250 milligrams per liter of fluid, S.S. in excess of 250 milligrams per liter of fluid, NH3N in excess of 25 milligrams per liter of fluid, or Phosphorus in excess of 8 milligrams per liter of fluid. The excessive strength surcharge shall be made on the following basis:
(1) Rate of surcharge based upon BOD. There shall be an additional charge of $0.38 per pound of BOD for BOD received in excess of 250 milligrams per liter of fluid;
(2) Rate of surcharge based upon S.S. There shall be an additional charge of $0.13 per pound of S.S. for S.S. received in excess of 250 milligrams per liter of fluid;
(3) Rate of surcharge based upon NH3N. There shall be an additional charge of $1.26 per pound of ammonia for NH3N received in excess of 25 milligrams per liter of fluid; and
(4) Rate of surcharge based upon Phosphorus. There shall be an additional charge of $3.93 per pound of Phosphorus received in excess of 8 milligrams per liter.
(C) The determination of S.S., BOD, NH3N, and Phosphorus contained in the waste shall be in accordance with the latest copy of Standard Methods for the Examination of Water, Sewage, and Industrial Wastes, as written by the American Public Health Association, the American Water Works Association, and the Water Pollution Control Federation, and in conformance with Guidelines Establishing Test Procedures for Analysis of Pollutants, published in the Federal Register on October 16, 1973 (40 C.F.R. 136.1 et seq.).
