1 GENERAL 1.1 Scope This Standard establishes requirements for FOG (Fats, Oils, and Greases) disposal systems. FOG disposal sys- tems shall be designed to (a) remove FOG from effluent (b) retain separated FOG (c) internally dispose retained FOG by means and methods of mass and volume reduction as required by para. 4.3.2 The use of alternate materials or methods are permit- ted, provided the proposed material and method com- plies with the performance requirements and intent of this Standard. 1.2 Units of Measurement Where values are stated in U.S. Customary units and the International System of Units (SI), the U.S. Customary units shall be considered as the standard. In this Standard, gallons (U.S. liquid) per minute is abbreviated gpm and liters (metric liquid) per minute is abbreviated L/min. 1.3 References The following is a list of publications referenced in this Standard: AASHTO H20-44, Standard Specifications for HS-20, Highway Loading Publisher: American Association of State Highway and Transportation Officials (AASHTO), 444 North Capitol Street NW, Suite 249, Washington, DC 20001 ACI 318, Specification for Steel Reinforcement Publisher: American Concrete Institute (ACI), 38800 Country Club Drive, Farmington Hills, MI 48331.

3.2 Application Documentation Each FOG disposal system shall be provided with complete applicationinstructions including, butnotlim- ited to, the following: (a) flow control and/or vent requirements (b) any separate trapping requirements (c) elevation and accessibility requirements (d) safety and health-related instructions (e) wiring instructions to reference national or local codes (f) clean-out locations (g) instructions that show the clearances required for maintenance, cleaning, and prevention of hazards 3.3 Maintenance and Operation Documentation Each FOG disposal system shall be provided with maintenance and operation documentation, which include a troubleshooting guide as well as instructions for performing necessary servicing or obtaining outside servicing. Units shall be provided with complete mainte- nance and operating instructions. 3.4 Installation 3.4.1 Installation shall be in accordance with the manufacturer’s recommendations and the applicable plumbing codes. 3.4.2 Each unit shall be packaged with illustrated directions detailing correct installation procedures. 3.4.3 In buried applications of FOG disposal sys- tems, access to each system shall be provided. There shall be access for each 10 ft (3.03 m) of length for FOG disposal systems over 20 ft (6.1 m) long. Each access opening shall have a leak-resistant closure (i.e., lid) that cannot slide, rotate, or flip exposing the opening, and which does not require the use of mechanical fasteners and be of a vandal-resistant type. 3.4.4 Manholes, ifapplicable,shall extendto grade; have a minimum diameter size of20 in. (510 mm) diame- ter or 20 in. ✕ 20 in. (510 mm ✕ 510 mm); and shall be provided with a fitted, water-tight cover. Manholes shall be capable of withstanding all anticipated loads and comply with IAPMO PS-1, para.
