A. When required by the city, the owner of any property serviced by a building sewer carrying industrial wastes shall install a suitable control structure, together with such necessary meters and other appurtenances in the building sewer to facilitate observation, sampling and measurement of the wastes. Such structure and equipment, when required, shall be constructed at the owner's expense in accordance with plans approved by the city and shall be maintained by the owner so as to be safe and accessible at all times.
B. All measurements, tests, and analyses of the characteristics of water and waste to which reference is made in this chapter shall be determined in accordance with 40 CFR 136, "Guidelines Establishing Test Procedures For The Analysis Of Pollutants", the latest edition of "Standard Methods For The Examination Of Water And Wastewater" and shall be determined at the control structure provided or upon suitable samples taken at said 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 effluent constituents and their effect upon the treatment works and to determine the existence of hazards of life, health and property. Sampling methods, location, times, duration and frequencies are to be determined on an individual basis subject to approval by the city.
C. The owner of any property serviced by a building sewer carrying industrial wastes may, at the discretion of the city, be required to provide laboratory measurements, tests and analyses of waters or 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. The number, type and frequency of sampling and laboratory analyses to be performed by the owner shall be as stipulated by the city. The industry must supply a complete analysis of the constituents of the wastewater discharge to assure that there is compliance with federal, state and local standards. The owner shall report the results of measurements and laboratory analyses to the city at such times and in such manner as prescribed by the city. The owner shall bear the expense of all measurements, analyses and reporting required by the city. At such times as deemed necessary, city reserves the right to take measurements and samples for analysis by an outside laboratory. (Ord. 96, 10-5-1987)
