(A) Grease, oil and sand interceptors shall be provided when, in the opinion of the Public Works Director, they are necessary for the proper handling of liquid wastes containing floatable grease in excessive amounts as specified in § 53.05(D) or any flammable wastes, sand or other harmful ingredients; except that such interceptors shall not be required for private living quarters or dwelling units. All interceptors shall be of a type and capacity approved by the Public Works Director and shall be located as to be readily and easily accessible for cleaning and inspection. In the maintaining of these interceptors the owner(s) shall be responsible for the proper removal and disposal by appropriate means of the captured material and shall maintain records of the dates and means of disposal which are subject to review by the Public Works Director. Any removal and hauling of the collected material not performed by owner(s) personnel must be performed by currently licensed waste disposal firms.
(1) A grease trap or grease interceptor shall be required to receive the drainage from fixtures and equipment with grease-laden waste located in food preparation areas, such as in restaurants, hospitals, nursing homes and elderly living facilities, school kitchens, bars, restaurants, clubs or any commercial venture that cooks and sells food.
(2) The user at the user's expense shall maintain all grease traps to assure proper operation and efficiency and prevent disposal of grease into the city’s sanitary sewer collection system. Maintenance of a grease trap shall include the complete removal of all content, including floating materials, wastewater, and bottom sludge and solids. Discharging of removed waste back into the trap from which it was removed or any other grease trap, for the purpose of reducing the volume to be disposed, is prohibited. This service shall also include a thorough inspection of the trap and its components. Any needed repairs shall be noted. Repairs shall be made at the user's expense.
(3) The grease trap must be emptied and maintained according to the manufacturer’s recommendation, frequently enough to prevent disposal or carry over of grease into the city’s sanitary sewer system.
(4) All waste removed from each grease trap must be disposed of in a lawful manner through a hauler of animal waste or other disposal manner authorized by state law. In no way shall any portion of the waste material be returned to any private or public portion of the city's sanitary sewer collection system.
(5) A grease trap in any facility listed in division (A)(1), above, is subject to inspection by the Public Works Director or designee. If the grease trap is in violation of this section, the owner or operator of the facility will be guilty of a Class 2 misdemeanor and subject to being punished in accordance with § 10.99 of this code. In addition, a civil penalty shall be imposed for the equipment, materials and labor expended by the city in remediating the grease from the city’s sanitary sewer collection system, based upon the resolution in effect for such costs. If those costs are not paid to the city within 60 days of billing, they shall be turned over to collections.
(B) Where pretreatment or flow-equalizing facilities are provided or required for any waters or wastes, they shall be maintained continuously in satisfactory and effective operation by the owner(s) at his or her expense.
(C) When required by the Public Works Director, the owner(s) of any property serviced by a building sewer carrying industrial wastes shall install a suitable structure together with such necessary meters and other appurtenances in the building sewer to facilitate observation, sampling and measurement of the wastes. Such structures, when required, shall be accessible and safely located, and shall be constructed in accordance with plans approved by the Public Works Director. The structure 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.
(D) No statement contained in this chapter 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.
