All measurements, tests and analyses of the characteristics of waters 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, and shall be determined at the control manhole provided, or upon suitable samples taken at the control manhole, except for applications for NPDES permits and reports thereof which shall be conducted in accordance with rules and regulations adopted by the USEPA (40 CFR 136). 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. 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. The particular analysis involved will determine whether a twenty-four- hour (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 twenty-four-hour (24-hour) composites determined from periodic grab samples.
All discharges subject to local, state, or federal regulations must retain and preserve, for at least three (3) years, any records, books, documents, memoranda, reports, correspondence, and any and all summaries relating to monitoring, sampling, and chemical analyses made by or on behalf of a discharger in connection with its discharge.
Any required monitoring activities, supplies, laboratory costs (whether in-house or by a contract laboratory) that must be utilized or performed by the Town, will be charged to the user. Any tests or services utilized from a contract laboratory will be charged at the laboratory's rates.
