(A) Any person who owns or operates a gravity separation interceptor shall properly maintain the interceptor at all times. 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. 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% by the accumulation of sediment and floating oils and greases.
(B) The use of chemicals or other materials for the emulsification, suspension or dissolution of oil and grease is prohibited.
(C) The use of microbiological agents to metabolize oil and grease shall be reviewed for approval on a case-by-case basis. The user shall submit a written request to the Director for the use of a microbiological agent prior to the use of that agent.
(D) When an interceptor is cleaned, the removed sediment and floating material shall be legally disposed of other than to the city's collection system or POTW.
(E) If the interceptor is not maintained adequately under the conditions of use, the interceptor shall be re-sized and the user shall install one which is effective in accomplishing the intended purpose.
(F) The owner, lessee, sub-lessee, proprietor, operator or superintendent of any facility required to install an interceptor is individually and severally liable for any failure to properly maintain the interceptor.
