(A) In order that the rates and charges may be in proportion to the service rendered to users, the town shall base its charges not only on the volume, but also on strength and character of the stronger-than-normal domestic sewage and wastes which it is required to treat and dispose of. 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 sewage system, in such manner and by such method as the town may deem practicable in the light of the conditions and attending circumstances of the case, in order to determine the proper charge. The user shall furnish a central sampling point available to the town at all times. An excessive strength surcharge shall be assessed to users determined to be contributors of excessive strength, defined as being in excess of normal domestic sewage strength. Additional charges for treating stronger-than-normal domestic sewage shall be made on the following basis:
(1) For rate surcharge based upon suspended solids, there should be an additional charge of $0.26 per pound of suspended solids received in excess of 200 milligrams per liter of fluid; and
(2) For rate surcharge based upon BOD, there shall be an additional charge of $0.26 per pound of biochemical oxygen demand for BOD received in excess of 200 milligrams per liter of fluid.
(B) The determination of suspended solids, five day biochemical oxygen demand, and ammonia nitrogen 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 Waterworks Association, and the Water Pollution Control Federation, and in conformance with guidelines establishing test procedures for analysis of pollutants, regulation 40 C.F.R. part 136, published in the Federal Register on October 16, 1973.
