(A) The owner of any property serviced by a building sewer carrying industrial wastes, or other users who discharge or could potentially discharge greater than normal domestic strength wastewater to the public sewer shall provide, where required by the city, laboratory measurements, tests and analysis of waters and wastes to illustrate compliance with this chapter and any special conditions for discharge established by the city or regulatory agencies having jurisdiction over the discharge.
(B) The number, type and frequency of laboratory analysis to be performed by the owner shall be as stipulated by the city or regulatory agency, and shall be such that the wastewater can be adequately characterized so that fair and equitable user charges may be accessed to the owner and to assure that compliance with the federal, state and local standards are being met. The owner shall report the results of measurements and samples for analysis by an outside laboratory service.
(C) All measurements, tests and analysis 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 IEPA Division of Laboratories Manual of Laboratory Methods, and shall be determined at the monitoring manhole or sampling location as specified in this chapter or other approved location. In the event that no special manhole has been required, the meter 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 of life, limb and property. The particular analysis involved will determine whether a 24-hour composite of all outfalls of a premise is appropriate or whether a grab samples or samples should be taken. Normally, but not always, BOD suspended solids and ammonia nitrogen analysis are obtained from 24-hour composites of all outfalls, whereas pHs are determined from periodic grab samples.
