(A) When required by the district, a user shall install suitable measuring, sampling and analyzing devices. These structures or devices, when required, shall be accessibly and safely located, and shall be constructed in accordance with plans approved by the Superintendent. The structures or devices 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.
(B) The district shall have the right to periodically or continuously inspect the monitoring facilities, to measure, sample and analyze the user’s flow and to analyze the samples obtained by the user. In the event of any discrepancy between the flows or loads determined by the district and the user, the values determined by the district shall be used for billing purposes.
(C) All measurements, tests and analyses of the characteristics of waters and wastes to which reference is made in this subchapter shall be determined in accordance with the latest editions of Standard Methods for the Examination of Water and Wastewater, published by the American Public Health Association, and also regulations Title 40 C.F.R. part 136, “Guidelines Establishing Test Procedures for Analysis of Pollution,” “A.S.T.M. Standards, Part 23, Water; Atmospheric Analysis” by the American Society for Testing and Materials and “Methods for Chemical Analysis of Water and Wastes” by the United States Environmental Protection Agency, and shall be determined at the control manhole provided, or upon suitable samples taken at the control manhole.
(1) 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.
(2) Sampling shall be carried out by customarily accepted methods to reflect the effect of constituents on 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 premise is appropriate or whether a grab sample or samples should be taken. Where necessary because of wastewater characteristics, where conversion information is provided to the district, and when approved by the Superintendent, oxygen demand may be reported as COD for conversion to BOD.
