All measurements, tests and analyses of the characteristics of water and wastes to which reference is made in this sewer chapter shall be determined in accordance with 40 C.F.R. Part 136, Guidelines Establishing Test Procedures for Analysis of Pollutants, and shall be determined at the control structure provided, or upon suitable samples taken at the control structure. In the event that no special structure has been required, the control structure shall be considered to be the nearest downstream manhole in the public sewer from 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 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, BOD and suspended solids analyses are obtained from 24-hour composites of all outfalls whereas pHs are determined from periodic grab samples).
