For the purpose of this subchapter, the following definitions shall apply unless the context clearly indicates or requires a different meaning.
ALTERNATIVE PRETREATMENT TECHNOLOGY. Includes, but is not limited to, devices that are used to trap, separate and hold grease from wastewater and prevent it from being discharged into the sanitary sewer collection system.
FATS, OILS AND GREASES (FOG). Organic polar compounds derived from animal and/or plant sources that contain multiple carbon chain triglyceride molecules. These substances are detectable and measurable using analytical test procedures established in the United States Code of Federal Regulations 40 C.F.R. 136, as may be amended from time to time. All are sometimes referred to herein as GREASE or GREASES.
FOOD SERVICE ESTABLISHMENTS (FSE). Those establishments primarily engaged in activities of preparing, serving or otherwise making available for consumption by the public such as restaurant, commercial kitchen, caterer, hotel, school, hospital, prison, correctional facility and care institution. These establishments use one or more of the following preparation activities: cooking by frying (all methods), baking (all methods), grilling, sauteing, rotisserie cooking, broiling (all methods), boiling, blanching, roasting, toasting or poaching. Also included are infrared heating, searing, barbecuing and any other food preparation activity that produces a hot, non-drinkable food product in or on a receptacle that requires washing.
GREASE CONTROL DEVICE. A grease control device for the purpose of this subchapter includes grease traps, grease interceptors and alternative pretreatment technology.
GREASE INTERCEPTOR. A structure or device designed for the purpose of removing and preventing fats, oils and grease from entering the sanitary sewer collection system. These devices are often below-ground units in outside areas and are built as multi-chamber baffled tanks.
GREASE TRAP. A device for separating and retaining waterborne greases and grease complexes prior to the wastewater exiting the trap and entering the sanitary sewer collection and treatment system. Such traps are typically compact under-the-sink units that are near food preparation areas.
MINIMUM DESIGN CAPABILITY. The design features of a grease interceptor and its ability or volume required to effectively intercept and retain greases from grease-laden wastewaters discharged to the public sanitary sewer. Minimum design standards shall be per current California Plumbing Code and as specified in city standards.
RENDERABLE FOG. Uncontaminated fats, oils and grease from the food preparation process that can be used as a source of material that is free of impurities and can be recycled into products such as animal feed and cosmetics.
USER. Any person, including those located outside the jurisdictional limits of the city who contributes, causes or permits the contribution or discharge of wastewater into sewers within the city’s boundaries, including persons who contribute such wastewater from mobile sources, such as those who discharge hauled wastewater.
