Whereas, the Town of Deer Trail, Colorado desires to prevent sanitary overflows from grease accumulation in its sanitary sewer mains.
Be it ordained by the Board of Trustees for the Town of Deer Trail Colorado, that:
Section 1. Purpose.
- The purpose of this Ordinance is to prevent sanitary sewer blockages and obstructions by controlling the deposit of fats, oils, and greases into the sanitary sewer system from industrial or commercial sources.
Section 2. Definitions.
- For the purpose of this Ordinance, the following words shall have the following meaning unless context indicates otherwise:
Fog means fats, oil and grease, a term which generally refers to animal and vegetable glycerides discharged from food processing and serving industries. These substances are detectable and can be measured using standard analytical techniques. They are generally referred to herein as "grease" or "greases".
Food Service Facility means a facility that prepares and/or packages food for sale or consumption. These include, but are not limited to, restaurants, food processing facilities, food manufacturers, seafood packing plants, bakeries, lounges, hospitals, hotels, nursing homes, churches, schools, dairies, slaughterhouses, meat packers, food courts, caterers, and theme parks.
Grease means animal and vegetable glycerides discharged from food processing and serving industries.
Grease Interceptor means 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 two or three chamber baffled tanks.
Grease Trap means a device to which grease and food wastes are directed from the food service facility operations and that functions to separate and retain waterborne greases and solid food particles prior to the sewage exiting the trap and entering the sewer system. It also collects solids and grease from kitchen floor drains. Such traps are typically compact under-the-sink units that are near food preparation areas.
Minimum Design Capability means 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.
