1.4 Definitions sample: a representative portion of system discharge consisting of four discrete quantities of at least 1 L each. stabilize: when the functions of separation, retention, and disposal are fully operational in accordance with the manufacturer’s requirements. 2 GENERAL REQUIREMENTS 2.1 Construction FOG disposal systems shall be manufactured from materials such as, but not limited to, concrete, steel, stainless steel, fiberglass, reinforced polyester, polyethylene, and polypropylene. Such materials shall be rated and suitable for the intended application. 2.1.1 Design Performance. FOG disposal system designs and methods shall produce an effluent quality not to exceed 100 mg/L FOG as stated in para. 4.3.2. 2.1.2 Flow Rate. FOG disposal systems shall be described by total gpm influent. 2.1.3 Inlet and Outlet Connections. The inlet and outlet connections ofthe FOG disposal system shall be either a female pipe thread or a plain end diameter to allow hubless coupling connections. Tapered threads shall comply with ASME B1.20.1. Hubless connections shall comply with the outside dimension for the given pipe size in accordance with ASTM A 888 or ASME A112.3.1. 2.2 Electrical All electrical components used in the FOG disposal system shall conform to the appropriate sections of UL Standards 499, 917, 1004, and 1585 as listed in para. 1.3. 2.3 Manufacture 2.3.1 FOG disposal systems shall be free of manufacture and/or material defects that affect performance, or serviceability. 2.3.2 FOG disposal systems shall be designed to withstand anticipated installation and use associated FOG loading. 2.3.3 Each FOG disposal system and cover designated for buried application shall be structurally designed to withstand earth or other loads pertinent to its location. 2.3.4 FOG disposal systems and covers for buried applications in nonvehicular traffic areas shall be designed for an earth load of not less than 500 psf (24 kPa) when the maximum coverage does not exceed 3 ft (0.9 m).
