(A) (1) 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 the 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 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.
(2) 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:
Material

Additional Charge

Ammonia nitrogen received in excess of 30 mg/l of fluid | $0.80 per pound |
BOD received in excess of 200 mg/l of fluid | $0.25 per pound |
Suspended solids received in excess of 200 mg/l of fluid | $0.25 per pound |
(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, 40 C.F.R. part 136, published in the Federal Register on October 16, 1973.
