§ 14.12.270 — Interceptor maintenance

14.12.270 - Interceptor maintenance.

A. Any person who owns or operates an interceptor shall properly maintain it at all times to ensure the continued operation of the great interceptor, as designed, and to avoid causing a surcharge or overflow. The interceptor shall be cleaned as often as necessary to ensure that sediment and floating materials do not accumulate to impair the efficiency of the interceptor and odors do not cause a public nuisance. An interceptor is not considered to be properly maintained, if for any reason the interceptor is not in good working condition or if the operational fluid capacity has been reduced by more than 25 percent by the accumulation of floating material, sediment, oil or grease, or other liquids that have limited or no solubility in water. B. The use of chemicals, enzymes, proteins or other materials to emulsify, suspend, or dissolve oil and grease is prohibited. If a user is found using any of these materials, the materials may be confiscated without restitution to the user and the user may be subject to enforcement actions. C. No user shall use any microbiological product in a grease interceptor that was not specifically designed to use such microbiological agents to metabolize fats, oils, and greases. If a user is found using any of these materials, the materials may be confiscated without restitution to the user and the user may be subject to enforcement actions. D. When an interceptor is cleaned, the entire contents of the interceptor from all chambers and sample box shall be removed. The removed sediment, solids, liquid and floating material shall not be reintroduced or decanted into the interceptor, sample box, sewer cleanout, other interceptor or other unlawful opening of a collection system or private sewer systems and shall be lawfully disposed of other than to the private sewer systems, POTW or storm drain, and shall not be reintroduced into the interceptor or discharged into another interceptor at another location not designed and permitted to accept such waste. E. If the interceptor is not maintained adequately, then the interceptor shall be resized and the user shall install one that is effective in accomplishing the intended purpose, or the City may require a mandatory pumping schedule for the interceptor. Failure to pump the interceptor as required is a violation of this chapter and may subject the user to enforcement action. F. The owner and lessee, sub-lessee, proprietor, operator and superintendent of any facility, required to install an interceptor or use an existing interceptor are individually and severally liable for any failure to properly maintain such interceptor.
