(A) Resturants (existing and new). All restaurants or food service facilities shall install an approved grease interceptor which is of sufficient size so as to prevent excessive discharges of grease into the City’s sewerage system. The grease interceptor shall be easily accessible for inspection by the control authority. Exceptions to the installation of a grease interceptor shall be determined on a case-by- case basis by the control authority. The control authority shall take into account the following items when determining exceptions:
(1) Size of restaurant;
(2) Meals served per day;
(3) Daily water usage based upon water bills;
(4) Seating capacity; and
(5) Dishwasher and garbage disposal facilities on-hand.
(B) Car washes, radiator shops, vehicle service stations, and garages (existing and new). Car washes will be required to install mud pits and a gravity separating device designed to prevent the discharge of sand, silt, oil, and grease to the City’s sewerage system. Radiator shops, vehicle service stations, and garages will be required to plug floor drains and remove sinks in the service bays and repair shops.
(C) Laundries and dry cleaners (existing and new). After the effective date of this chapter, all laundries and dry cleaners or similar establishments shall install lint filters and a gravity separating device of a size and design approved by the control authority. They shall also install any other pretreatment facility required by the control authority to ensure their compliance with all requirements and specifications of this chapter. Establishments in existence prior to the effective date of this chapter shall install an appropriate pretreatment system if, in the opinion of the control authority, the system is warranted.
(D) Existing gravity separating device and grease interceptors. If the control authority finds that a grease interceptor or gravity separating device installed prior to the effective date of this chapter is incapable of retaining adequately the grease or sand and oil in the wastewater flow from a service station, car wash, restaurant, or similar establishment, the control authority shall give the proprietor a written notice requiring that an adequate interceptor or gravity separating device be installed within 90 days.
(E) Approved designs. The design of grease interceptors and gravity separating devices shall follow the currently adopted Plumbing Code. The user shall submit a proposed design to the control authority for review and approval.
(F) Maintenance of grease interceptors and gravity separating devices. Any grease interceptor or gravity separating device required by this chapter shall be readily accessible for inspection and properly maintained to assure that the accumulations of grease or sand and oil do not impair its efficiency or pass out with the effluent. All users required to use and maintain a grease interceptor or gravity separating device shall maintain a maintenance record. This record shall include the date, the name of the person who cleaned it, and the disposal site of the waste. The report shall be reviewed by the control authority at each routine inspection. Persons hauling wastes and wastewater removed from these interceptors or gravity separating devices shall be registered to do so by the proper permitting agency. An interceptor or gravity separating device shall not be considered properly maintained if material accumulations total more than 25% of the operating fluid capacity.
