§ 50.31 MEASUREMENTS, TESTS, AND ANALYSES.
   (A)   The town may require users of the treatment works, other than residential users, to supply pertinent information on wastewater flows characteristics. These measurements, tests, and analyses shall be made at the users' expense. If made by the town, an appropriate charge may be assessed to the user at the option of the town.
   (B)   The strength of wastewaters shall be determined, for periodic establishment of charges provided for in this chapter, from samplings taken at the aforementioned structure at any period of time and of such duration and in such manner as the town may elect, or, at any place mutually agreed upon between the user and the town. Appropriate charges for sampling and analysis may be assessed to the user at the option of the town. The results of routine sampling and analysis by the user may also be used for determination of charges after verification by the town.
   (C)   All measurements, tests, and analyses of the characteristics of water and wastes to which reference is made in this chapter shall be determined in accordance with the latest edition of "Standard Methods for the Examination of Water and Wastewater", published by the American Public Health Association, and shall be determined at the control manhole provided, or upon suitable samples taken at the control manhole.
      (1)   Application for NPDES permits and report thereof which shall be conducted in accordance with rules and regulations adopted by the USEPA published in the Federal Register October 16, 1973, (38 CFR 20758) and any subsequent revisions subject to approval by the town.
      (2)   In the event that no special manhole has been required, the control manhole shall be considered to be the nearest downstream manhole in the public sewer to the point at which the building sewer is connected.
      (3)   Sampling shall be carried out by customarily accepted methods to reflect the effect of constituents upon the sewage works and to determine the existence of hazards to life, limb, and property.
      (4)   The particular analysis involved will determine whether a 24-hour composite of all outfalls of a premises is appropriate or whether a grab sample or samples should be taken. Normally, but not always, BOD and suspended solids analysis are obtained from 24-hour composites of all outfalls whereas pHs are determined from periodic grab samples.
