A. Definitions: For the purposes of this chapter, the following terms shall have the meanings ascribed to them in this section:
FOOD SERVICE FACILITIES: Those establishments primarily engaged in activities of preparing, serving, or otherwise making available for consumption foodstuffs and that utilize 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, nondrinkable food product in or on a receptacle that requires washing. Food service facilities include restaurants, cafeterias, hotels, motels, hospitals, nursing homes, schools, grocery stores, prisons, jails, churches, camps, caterers, manufacturing plants, or any other users of the sanitary sewer system as determined by the city of Skiatook building inspector or code official who discharge applicable waste. A food service facility, as defined herein, does not include a self-contained single-family dwelling.
GREASE: Material composed primarily of fats, oils and grease ("FOG" hereinafter) from animal, vegetable, seed or nut sources. The terms fats, oils and grease shall be deemed as grease by definition. The term "grease" does not include petroleum based products or waste.
GREASE INTERCEPTOR: A structure or device designed for the purpose of removing and preventing fats, oils, and greases from entering the sanitary sewer collection system. These devices are often installed below grade outside of the building which the interceptor serves and are built as a two (2) or three (3) chamber tank. As defined in the international plumbing code, a grease interceptor is a grease removal device whose rated flow exceeds fifty (50) gallons per minute and is located outside of the building it services.
GREASE TRAP: A device for separating and retaining 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 located in or near food preparation areas. As defined in the international plumbing code, a grease trap is a grease removal device whose rated flow is fifty (50) gallons per minute or less and is located inside a building.
OIL/WATER SEPARATOR: An approved and industry standard system that is specifically designed and manufactured to separate oil from water. The system shall allow the oil to be collected and removed on a regular basis as to prevent it from being discharged into the wastewater collection system. Only oil/water separators manufactured for that specific operation will be approved. Product details and specifications shall be required to be provided to the building inspector or code official to ensure that said oil/water separator meet or exceed the requirements of this section.
USER: Any person, entity or establishment including those located outside the municipal limits of the city of Skiatook who contributes, causes, or permits the discharge of wastewater into Skiatook's sanitary sewer collection or treatment system, including persons who contribute such wastewater from mobile sources, such as those who discharge hauled wastewater.
B. Control Plan For FOG And Food Waste:
1. Prior to the commencement of any new construction, renovation or expansion of food service facilities, the owner/operator shall be required to submit to the building inspector or code official for approval, a FOG and food waste control plan what will effectively control the discharge of grease (FOG) and other food based waste into the sanitary sewer collection system.
2. All existing food service facilities shall also be required to submit a FOG and food waste control plan that will effectively control the discharge of grease (FOG) and other food based waste into the sanitary sewer collection system. Existing food service facilities shall not be exempt from the requirements of submission of a FOG and food waste control plan for approval by the building inspector or code official.
C. General Criteria:
1. Installation Requirements: All existing or proposed food service facilities within the municipal limits of the city of Skiatook or utilizing the city of Skiatook's sanitary sewer collection and treatment system shall be required to install, at the user's expense, an approved, properly installed, operated and maintained grease trap and/or grease interceptor.
2. Sanitary Sewer Flows: Sanitary sewer flowage from toilets, urinals, lavatories, etc., shall not be discharged into a grease trap/grease interceptor. These flows shall be conveyed separately to the sanitary sewer system.
3. Floor Drains: Only floor drains which collect and discharge or have the potential to collect and discharge grease shall be connected to a grease trap/grease interceptor.
