(A)   Grease and oil traps or other interceptors shall be provided at the user's expense, when such user operates an establishment preparing, processing or serving food and/or food products. Grease interceptors may also be required in other industrial or commercial establishments when they are necessary for the proper handling of liquid wastes containing oil and/or grease in amounts in excess of 200 mg/l by weight fat soluble, or for any flammable wastes. All such traps, tanks, chambers or other interceptors shall be of a type and capacity approved by the Director and shall be readily and easily accessible for cleaning and inspection. All such interceptors shall be serviced and emptied of the waste content as required, but not less often than every 30 days, in order to maintain their minimum design capability to intercept oils and greases from the wastewater discharged to the public sanitary sewer.
   (B)   No waste removed from the interceptor shall be reintroduced into the sanitary sewer or back into the interceptor, which will cause the interceptor's discharge to exceed sewer use ordinance limits. The owner shall be responsible for the sanitary disposal of such waste.
   (C)   The owner shall maintain a written record of trap maintenance for the prior three years. A copy of each monthly service record shall be sent to the Public Works Department no later than the fifteenth day of the month following service.
