A. The Orange County Sanitation District (OCSD) regulates all industrial wastewater discharges to the public sewer system. Any person desiring a permit to connect to the public sewer for the purpose of discharging any industrial waste shall submit an application to the OCSD. The application shall include complete information regarding the quantity and nature of the wastewater to be discharged. A copy of the industrial wastewater discharge permit issued by OCSD must be submitted to the city prior to city issuance of a certificate of occupancy.
B. The admission into the public sewers of any waters or wastes having any of the following shall be subject to review and approval of the City Engineer:
1. A five (5) day biochemical oxygen demand greater than three hundred (300) parts per million by weight;
2. More than three hundred fifty (350) parts per million by weight of suspended solids;
3. Any quantity of substances having the characteristics described in § 13.00.240;
4. An average daily flow greater than five percent (5%) of the average daily sewage flow of the city;
5. A peak flow of more than four (4) times its average daily flow; or
6. Additional prohibited discharges are listed in § 13.00.240.
C. Where necessary in the opinion of OCSD or the City Engineer, the owner shall provide, at his or her expense, such preliminary treatment or other remedial measures as may be necessary to meet the conditions set out in this article. Plans, specifications and any other pertinent information relating to proposed preliminary treatment facilities shall be submitted for review by OCSD, the City Engineer, and the Orange County Health Care Agency. No construction of such facilities shall commence until the review has been completed and written authorization for such construction has been received.
D. Where preliminary treatment facilities are provided for any waters or wastes, they shall be maintained continuously in satisfactory and effective operation by the owner at his or her expense.
E. When required by the City Engineer, the owner of any property served by a building sewer carrying industrial wastes shall install a suitable control manhole in the building sewer to facilitate observation, sampling and measurement of the wastes. Such manhole, when required, shall be accessibly and safely located, and shall be constructed in accordance with plans approved by the City Engineer. 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.
F. All measurements, tests, and analyses of the characteristics of waters and wastes to which reference is made in Chapter 13, shall be determined in accordance with the latest edition of Standard Methods for the Examination of Water and Sewage. Samples shall be taken at a control manhole. In the event that no special manhole has been provided, 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.
G. No statement contained in this article shall be construed as preventing any special agreement or arrangement between the city and any industrial concern whereby an industrial waste of unusual strength or character may be accepted by the city for treatment subject to payment therefor by the industrial concern.
