The city shall administer an interceptor program which is intended to prevent grease, sand and flammable liquids, and other substances which are likely to block or create a hazard within the city facilities from entering the system through use of interceptors or traps. The city may require any nondomestic user to install an interceptor or trap if the city discovers or determines subsequent to the connection that the building facility or operation of that user produces a waste with characteristics that would require installation of a trap or interceptor pursuant to this chapter. The installation of a proper interceptor or trap device shall be the responsibility of the parcel owner and the entity which applies for the connection or industrial user permit and the owner/proprietor of the business or entity whose operations cause or contribute to the necessity for an interceptor or traps. The city shall determine whether a grease trap, grease interceptor, or other interceptor is required on a case-by-case basis based on an evaluation of objective criteria including but not limited to factors such as those listed below:
A. The type of facility (a restaurant, bakery, cheese factory, yogurt shop, gas station, lube facility, etc.)
B. The volume of user's operation or business (such as meals served, number of seats, hours of operation);
C. Size and nature of facilities (including kitchen facilities) based on size, type, number of fixtures, and type of processing or cooking equipment used;
D. The type of service provided or operation such as dine-in meal service versus carry out meal service;
E. The type of foods or other materials used in cooking or manufacturing operations carried on within the user's facility;
F. The overall potential for grease-laden, flammable, or sand-laden discharges;
G. The existence of devices, procedures, or processes which are designed to minimize the amount of grease, sand, oil, or other flammable liquids from entering the newer system.
The design, location and procedures for operation of a required interceptor or trap shall be approved by the city. Such approval shall be obtained prior to the users connection of the facility to the city sewerage system, in the event of new construction or remodeling. In instances where a user has already connected and the city determines that an interceptor or trap must be installed, the user shall promptly provide for the installation of the interceptor or trap within a reasonable time frame (as may be set by the city), including providing such design plans and operational plans as may be required. The installation of an interceptor or trap as required by this chapter on an existing user facility shall occur within reasonable time not to, exceed sixty days after the user has been provided notice of the requirement that an interceptor or trap be installed. This sixty-day limit may only be extended by written agreement of the city. (Ord. 01-102 § 2 (part), 2001).
