A. Purpose And Policy: The purpose of this chapter is to aid in preventing the introduction and accumulation of fats, oils, grease, sand, and grit into the City's sanitary sewer system that may contribute to sanitary sewer blockages and obstructions. Food service establishments, grease haulers, car washes, garages, and other industrial or commercial establishments generating or collecting wastewater containing fats, oils, grease, or sand are subject to this chapter. This chapter regulates such users by requiring that interceptor devices and other approved strategies be installed, implemented and maintained in accordance with the provisions of this chapter and other applicable requirements of the City of Rigby.
The provisions of this chapter shall apply to all food service establishments within the City of Rigby service area and to all grease haulers providing service to any such food service establishment.
B. Definitions: Unless a provision explicitly states otherwise, the following terms and phrases, as used in this chapter, shall have the meanings hereinafter designated.
BROWN GREASE: | Floatable fats, oils, grease and settled solids produced during food preparation that are recovered from grease control devices. |
CITY: | The City of Rigby. |
ENFORCEMENT RESPONSE PLAN: | A plan that sets forth the process and procedures for enforcement of this chapter by the City of Rigby. |
FACILITY: | A food service establishment, carwash, garage, or other entity required to install and maintain an interceptor. |
FATS, OILS, AND GREASE (FOG): | Material, either liquid or solid, composed of fats, oils or grease from animal or vegetable sources. Examples of FOG include, but are not limited to, kitchen cooking grease, vegetable oil, bacon grease and organic polar compounds derived from animal and/or plant sources that contain multiple carbon triglyceride molecules. These substances are detectable and measurable using analytical test procedures established in the United States Code of Federal Regulations at 40 CFR Part 136, as may be amended from time to time. FOG may be referred to herein as "grease" or "greases." |
FOOD SERVICE ESTABLISHMENT (FSE): | Any commercial, industrial, institutional, or food processing facility discharging kitchen or food preparation wastewaters including, but not limited to, restaurants, commercial kitchens, caterers, motels, hotels, cafeterias, correctional facilities, prisons or jails, cafeterias, care institutions, hospitals, schools, and churches. Any establishment engaged in preparing, serving or otherwise making food available for consumption by the public shall be included. Such establishments use one or more of the following preparation activities: cooking by frying (all methods), baking (all methods), grilling, sautéing, rotisserie cooking, broiling, boiling, blanching, roasting, toasting, or poaching. Also included are infrared heating, searing, barbequing, and other food preparation activity that produces a hot, non-drinkable food product in or on a receptacle that requires washing. |
GREASE CONTROL DEVICE (GCD): | A device used to collect, contain, or remove food waste and grease from the wastewater while allowing the remaining wastewater to be discharged to the City's sanitary sewer system by gravity. Devices include grease interceptors, grease traps, automatic grease removal devices or other devices approved by the WWTP Superintendent. |
GREASE HAULER: | A contractor who collects the contents of a grease interceptor or trap and transports it to an approved recycling or disposal facility. A grease hauler may also provide other services related to grease interceptor maintenance for a FSE. |
GREASE INTERCEPTOR: | A structure or device, usually located underground and outside a FSE, designed to collect, separate and contain food waste and grease while allowing the wastewater to be discharged to the City of Rigby's sanitary sewer system by gravity. |
GREASE REMOVAL DEVICE: | An active, automatic device that separates and removes FOG from effluent discharge and that cleans itself of accumulated FOG at least once every twenty-four hours utilizing electromechanical apparatus. |
GREASE TRAP: | A device typically located indoors and under the sink or in the floor, designed for separating and containing grease prior to the wastewater exiting the trap and entering the sanitary sewer system. Such devices are typically passive (gravity fed) and compact with removable baffles. |
GRIT: | Sand, gravel, cinder, or other heavy solid materials that are heavier than the organic biodegradable solids in the wastewater. Grit also includes eggshells, bone chips, seeds, coffee grounds, and large organic particles, such as food waste. |
INTERCEPTOR: | A treatment tank designed to intercept and collect fats, oils, grease, sand, or grit in a wastewater flow, and prevent their entry into the sanitary sewer system. |
