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 themanufacturer’s requirements.
2 GENERAL REQUIREMENTS2.1 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 theintended application.
2.1.1 Design Performance.FOG disposal system designs and methods shall produce an efluent quality not toexceed 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 of the FOG disposal system shall be either a femalepipe thread or a plain end diameter to allow hubless coupling connections. Tapered threads shall comply with ASMEB1.20.1.Hubless connections shall comply with the outside dimension for the given pipe size in accordance with ASTMA888 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 Standards499,917,1004, 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,orserviceability.
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 withstandearth 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 anearth load of not less than 500 psf (24 kPa) when the maximum coverage does not exceed 3 ft (0.9 m).
2.3.5 FOG disposal systems and covers for installation in traffic areas shall be designed to withstand an AASHTOH20-44 wheel load, an additional 3 ft (0.9 m) earth load with an assumed soil weight of 100 psf (4.8 kPa), and 30 psf(1.4 kPa) fluid equivalent sidewall pressure.
2.3.6 Internal construction shall be designed to withstand the maximum expected conditions that include, but are notlimited to, chemical, thermal, electrostatic, and hydrostatic pressure.
3 SPECIAL REQUIREMENTS
3.1 Separation/Retention Efficiency
FOG disposal systems, based on a hydromechanical grease interceptor principle, shall have a minimum separation/retention efficiency in accordance with ASME A112.14.3 or PDl-G101.FOG disposal systems, based on a gravity greaseinterceptor principle, shall be designed in accordance with IAPMO/ANSl Z1001.
3.2 Application Documentation
Each FOG disposal system shall be provided with complete application instructions including, but not limited to, thefollowing:
(a) ali flow control and/or vent requirementsb) any separate trapping requirements
(c) all elevation and accessibility requirements
(d) all safety and health‐related instructions
(e) all wiring instructions to reference national or local codes
(f) all clean‐out locations
(g) all 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 maintenance 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 ofFOG disposal systems, 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 that does not require the use of mechanical fasteners and be of a vandal‐resistant type.
3.4.4 Manholes, ifapplicable, shall extend to grade; have a minimum diameter size of20 in. (510 mm) diameter or 20 in. (510 mm) × 20 in. (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/ANSI Z 1001, which requires that all manholes have a leak‐resistant closure that, when properly installed, cannot slide, rotate, or flip exposing the opening, and that does not require the use of mechanical fasteners.
