(A) Grease interceptor sizing and installation shall conform to the current edition of the Uniform Plumbing Code.
(B) Grease interceptors shall be constructed in accordance with a design approved by the Public Works Director/Town Engineer and shall have a minimum of two compartments with fittings designed for grease retention.
(C) A grease interceptor shall be installed at a location where it shall be easily accessible for inspection, cleaning, and removal of intercepted grease. The grease interceptor may not be installed in any part of the building where food is handled. The location of the grease interceptor must meet the approval of the Public Works Director/Town Engineer.
(D) All grease interceptors shall be serviced and emptied of accumulated waste content as required in order to maintain minimum design capability or effective volume. These devices should be inspected at least monthly. Users who are required to maintain a grease interceptor shall:
(1) Provide for a minimum hydraulic retention time in accordance with the Uniform Plumbing Code; and
(2) Remove any accumulated grease cap and sludge pocket as required. Grease interceptors shall be kept free of inorganic solid materials such as grit, rocks, gravel, sand, eating utensils, cigarettes, shells, towels, rags, and the like, which could settle into this pocket and thereby reduce the effective volume of the device.
(E) All records will be made available for on-site inspection by representative of the town during all operating hours.
(F) Sanitary wastes are not allowed to be connected to sewer lines intended for grease interceptor service.
(G) Except as provided herein, for a period of one year following adoption of this subchapter, although installation of grease interceptors will be required, no enforcement actions will be taken under this subchapter for failure to achieve limits on grease discharges from grease interceptors. If, during this one-year period, an obstruction of a sewer main(s) occurs that causes a sewer overflow to the extent that an impact on the environment is realized and if the overflow or failure of the sanitary sewer collection system to convey sewage can be attributed in part or in whole to an accumulation of grease in the sewer main(s), the town will take appropriate enforcement actions, as stipulated in the Industrial Pretreatment Enforcement Plan and Sewer Use Ordinance, against the generator or contributor of the grease.
(H) Access manholes, with a minimum diameter of 24 inches, shall be provided over each grease interceptor chamber and sanitary tee. The access manholes shall extend at least to finished grade and be designed and maintained to prevent water inflow or infiltration. The manholes shall also have readily removable covers to facilitate inspection, grease removal, and wastewater sampling activities.
