(A) 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, published by the American Public Health Association, and Federal Regulation 40 C.F.R. part 136 entitled Guidelines Establishing Test Procedures for Analysis, and shall be determined at the control manhole provided, or upon suitable samples taken at the control manhole.
(B) 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, provided the City Engineer shall be permitted to take samples within the premises of the user, including lagoons, ponds and other places. 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 analyses 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, B.O.D. and suspended solids analyses are obtained from 24-hour composites of all outfalls, whereas pHs are determined from periodic grab samples). All discharges shall be in conformance with the NPDES permit.
