§ 50.58 CERTAIN RATES MODIFIED DUE TO STRENGTH, CHARACTER OF DISCHARGE.
   (A)   In order that the fees and charges may be justly and equitably adjusted to the service rendered, the town shall base its charges not only on the volume, but also on the strength and character of the sewage and wastes which it is required to treat and dispose of. The town shall require the owner or other user to determine the strength and content of all sewage and wastes discharged, either directly or indirectly, into the sanitary sewage system, in a manner and by the 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 owner or other user shall furnish a central sampling point available to the town at all times.
   (B)   Extra charges based on the strength of the sewage and liquid wastes shall be made on the following basis, with Phase I being implemented July 1, 2015, and Phase II being implemented on July 1, 2016:
      (1)   Fee surcharge based upon suspended solids. There shall be an additional charge of $0.30 (for Phase I and Phase II) per 1,000 gallons of flow for each 100 milligrams, or fraction thereof, of suspended solids in excess of 200 milligrams per liter of fluid.
      (2)   Fee surcharge based upon BOD. There shall be an additional charge of $0.30 (for Phase I and Phase II) per 1,000 gallons of flow for each 100 milligrams, or fraction thereof, of biochemical oxygen demand in excess of 200 milligrams per liter of fluid.
      (3)   Fee surcharge based upon ammonia-as-nitrogen. There shall be an additional charge of $0.81 (for Phase I and Phase II) per 1,000 gallons of flow for each ten milligrams, or fraction thereof, of ammonia-as-nitrogen in excess of 30 milligrams per liter of fluid.
      (4)   Fee surcharge based upon total phosphorus. There shall be an additional surcharge of $0.12 per 1,000 gallons of flow for each four milligrams, or fraction thereof, of total phosphorus in excess of eight milligrams per liter of fluid.
   (C)   To determine the strength of the sewage and wastes, samplings and analysis shall be made from time to time whenever it is deemed desirable by the town.
   (D)   The determination of suspended solids and five-day biochemical oxygen demand 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.
