(a) Wastewater Discharge Permits. The City of Campbell is not presently issuing permits for Industrial Users. Should the Industrial User constituency significantly change, the City may institute a permit to discharge into the public sewer system. Included would be the revisions to the monitoring and enforcement provisions of this chapter.
(b) Control structure or manhole required: When required by the City, the owner of any property discharging industrial wastes shall install a suitable control structure or manhole together with such necessary meters and other appurtenances in the sewer to facilitate observation, sampling, and measurement of the wastes. Such structure or manhole, meters and other appurtenances, when required, shall be accessible and safely located, and shall be constructed in accordance with plans approved by the City. These shall be installed by the owner at the owner’s expense, and shall be maintained by the owner so as to be safe and accessible at all times.
(c) The City may require installation of grease, oil, or sand interceptors to provide for proper handling of liquid wastes containing grease in excessive amounts or of any flammable waste, sand or harmful waste.
(d) All measurements, tests, and analyses of the characteristics of wastes to which references are made in this chapter shall be determined in accordance with the latest edition of “Standard Methods for the Examination of Water and Wastewater” or “Methods for Chemical Analysis of Water and Wastes”, and 40 CFR Part 136 (testing) and shall be determined at the control manhole provided or upon suitable samples taken at said control manhole. 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 sewer is connected. Sampling shall be carried out by customarily accepted methods to reflect the effects of the wastes upon the sewage system and to determine the existence of hazards to life, limb, and property. Sampling methods, location times, durations, and frequencies are to be determined on an individual basis subject to the approval of the City.
(e) The City shall request all users classified as Industrial Users to submit an analysis of their discharge showing a determination of the concentration of wastes contained in said discharge. Such analysis shall include all information requested on forms provided by the City. After the initial determination by the City, a repeat analysis may be requested from time-to-time in order to insure the accuracy of the industrial waste discharged and the rates charged.
