(A) Restaurants. All restaurants or similar establishments have an approved grease interceptor of sufficient size so as to prevent excessive discharges of grease into the city's sewer system. The grease interceptor must be easily accessible for inspection by the Director. Exceptions to the installation of a grease interceptor must be determined by a case-by-case basis by the Director. The Director must take into account the following items when determining exceptions:
(1) Size of restaurant;
(2) Meals served per day;
(3) Seating capacity;
(4) Dishwashing and garbage disposal facilities on-hand; and
(5) Any other criteria the Director deems applicable.
(B) Car washes, vehicle service stations and garages. Car washes and vehicle service stations or garages must be required to install and maintain a gravity-separating device designed to prevent the discharge of sand, silt, oil and grease to the city's sewer system.
(C) Laundries and dry cleaners. Not later than the effective date of the ordinance codified in this chapter all new laundries and dry cleaners or similar establishments must install a gravity-separating device of a size and design approved by the Director. They must also install any other pretreatment facility required by the Director to ensure their compliance with all requirements and specifications of this chapter. Establishments in existence before this date must install an appropriate pretreatment system if, in the opinion of the Director, the system is warranted.
(D) Other facilities. Grease, oil or sand interceptors must be provided in other new facilities when, in the opinion of the Director, they are necessary for the proper handling of liquid wastes containing grease in excessive amounts, or any flammable wastes, and other harmful ingredients. All interceptors must be of type and capacity approved by the Director, and must be located as to be readily and easily accessible for cleaning and inspection.
(E) Existing gravity separating device and grease interceptors. If the Director finds that a grease interceptor or gravity separating device installed before the effective date of the ordinance codified in this chapter is incapable of retaining adequately the grease or sand and oil in the wastewater flow from a service station, car wash or restaurant or similar establishment or other facility, the Director must give the proprietor a written notice requiring that an adequate interceptor or gravity separating device be installed within a reasonable time period.
(F) Approved designs. The Director may maintain for public use an information file of acceptable designs of grease interceptors and gravity separating devices. The installation of a design shown in the file or of any design meeting the size requirement set forth in this chapter or any recommendation of requirements made by the Director must not impute any liability to the city for the adequacy of the interceptor or gravity separating device under the actual conditions in use. The installation must not relieve the owner or proprietor of responsibility for keeping prohibited substances or substances above the limitations of this chapter out of the city's sewer system. If the interceptor, gravity separating device or other pretreatment facility is not adequate under the conditions of use, one must be constructed which is effective in accomplishing the intended purpose.
