(A) When required by the township, the owner of any property serviced by a building sewer carrying industrial wastes shall install a suitable control manhole together with such necessary meters and other appurtenances in the building sewer to facilitate observation, sampling and measurement of the wastes. The manhole, when required, shall be accessible and safely located and shall be constructed in accordance with plans approved by the Supervisor. The manhole shall be installed by the owner at his or her expense and shall be maintained by him or her so as to be safe and accessible at all times. 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 from the point at which the building sewer is connected.
(B) 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 most recent edition of The Standard Methods for the Examination of Water and Sewage and shall also conform with the Federal Register reprint of October 16, 1973 (40 C.F.R. part 136) which establishes guidelines for testing procedures for analysis of pollutants. All measurements, tests and analyses shall be determined at the control manhole and upon suitable samples taken at the manhole. It shall be the responsibility of the industrial customer to provide flow measuring and monitoring equipment and sampling equipment for each control manhole.
(C) 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 grab sample or samples should be taken.
