(A) FSE shall install grease removal device(s), at FSE expense, as required by the POTW Director.
(B) FSE shall hire a grease removal device manufacturer, commercial plumber, architect or engineer to determine the correct size, design and location for the grease removal device.
(C) The hired manufacturer, commercial plumber, architect or engineer should size interceptors for a 30-minute HRT and traps for the proper flow rating. The POTW Director will not advise any FSE about the specific installation or sizing of the grease removal device.
(D) FSE shall install only the size grease removal device that is recommended by the hired manufacturer, commercial plumber or engineer and approved by the POTW Director and the local code official.
(E) Flow control devices and solids screens shall be required prior to grease traps.
(F) The maximum size for an interceptor/trap shall be 2,000 gallons. If the calculated minimum size is larger than this, two or more interceptors of approximately equal size shall be installed in series.
(G) Grease removal device selection and installation shall be done according to all applicable laws and building codes, even where not indicated in this subchapter.
(H) Grease removal device installation and operation shall be done according to all manufacturer’s instructions, unless more stringent instructions are given by the POTW Director.
(I) All compartments of grease removal devices shall be readily and easily accessible for FSE maintenance requirements and town inspection.
(J) The following shall be connected to the grease removal device: all fixtures and drains to wastewater lines in kitchens, food and beverage prep and bar areas (exceptions may be made for drink fountains and condensate drains that are not flush with the floor). Automatic dishwashers shall be plumbed to grease interceptors, but shall not be plumbed to grease traps. Kitchens with automatic dishwashers bypassing a grease trap must have a pre-rinse sink present.
(K) Food grinders shall be connected to grease interceptor/traps. The interceptor/trap size should be increased by 30% to accommodate the high solid waste stream, and when connected to a grease trap, a solids interceptor will be required prior to the grease trap. It is strongly recommended that food grinder use be discontinued and the food grinder removed as it increases the FSE cost of installation and maintenance.
(L) In the case where grease removal device installation occurred before this subchapter was approved by town and the grease removal device does not meet the standards of this subchapter, the FSE shall upgrade its grease removal device, when the POTW Director determines it is necessary.
