(A) Discharge criteria.
(1) Where fats, oil and grease are by-products of food preparation and/or cleanup, reasonable efforts shall be made to separate waste fats, oil and grease into a separate containers for proper disposal. Waste fats, oil and grease shall not be discharged to any drains or grease interceptors. Such waste shall be placed in a container designed to hold such waste and either recycled or disposed of at suitable locations in accordance with division (C) below.
(2) Adequately sized grease interceptor shall mean a grease interceptor that does not allow a discharge of wastewater containing fats, oil or grease in excess of 100 mg/l or has not been found to be contributing to line stoppages or require sewer maintenance to prevent stoppages from occurring. It is the responsibility of the establishment to ensure compliance with the sanitary sewer discharge limitations.
(B) Maintenance, record keeping and grease removal.
(1) 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 and thereby reduce the effective volume of the grease interceptor.
(2) Grease interceptors shall meet the FOG policy’s compliance requirements and be maintained for efficient FOG removal and shall be cleaned every 90 days. Some establishments may need to clean interceptors more frequently. It is the responsibility of the establishment to monitor and clean interceptor as needed, but the cleaning frequency shall be no less than every 90 days. The town reserves the right to adjust cleaning frequency of individual establishments as needed.
(3) Interceptor maintenance log.
(a) Every establishment having a grease interceptor shall maintain a log of each pumping for the previous three years. This log shall include the date, time, name of the waste hauler and shall be kept in a conspicuous location on the premises of the establishment for inspection. Trip tickets or manifests shall be maintained for a period of three years to substantiate the maintenance log. Establishments shall keep their FOG discharge permit with the log. Permit and log shall be made immediately available to the utility staff upon request.
(b) A copy of the information required in the maintenance log, including trip tickets or manifests, must be submitted to the Utility Office when requested by the utility. The report shall be submitted to the Utility Office within 30 days of the utility request for the information.
(4) Cleaning procedures.
(a) An owner, manager or employee of the establishment shall supervise grease interceptor cleaning, and shall be physically present and observe the entire cleaning operation.
(b) The owner, manager or employee of the establishment shall cause the liquid waste hauler, transporter or other person cleaning or servicing the grease interceptor to evacuate all contents, including floating materials, wastewater and bottom sludges and solids. Skimming the surface layer of waste material, partial cleaning of the interceptor or use of any method that does not remove the entire contents of the collection device is prohibited. The suction of the floating materials shall be done prior to removal of other contents. After complete evacuation, the walls, top and bottom of the interceptor shall then be thoroughly scraped and the residue removed. The interceptor shall then be washed down and the residue removed. Upon completion of the servicing, the employee witnessing the cleaning shall make an inspection of the interior of the interceptor and then sign the trip ticket or manifest. The employee shall make an appropriate entry in the establishment log.
(c) Each grease interceptor pumped shall be fully evacuated unless the volume is greater than the tank capacity of the vacuum truck in which case the transporter shall arrange for additional transportation capacity so that the grease interceptor is fully evacuated within a 24-hour period.
(d) The return of gray water back into the interceptor from which the waste was removed is prohibited.
(e) All waste removed from each grease interceptor shall be disposed of at an establishment permitted and authorized to receive such waste in accordance with all applicable federal, state, and local regulations. In no way shall the pumped material be returned to any private or public portion of the sanitary sewer system.
(f) It shall be a violation for an establishment to allow grease interceptor waste to be removed from the premises by a transporter that does not have all applicable federal, state, or local permits or registrations. Transportation and disposal of grease or other materials generated by a grease interceptor shall be subject to all applicable federal, state and local regulations.
(g) It is strictly prohibited for any non-water portion of the grease interceptor’s contents to be pushed or flushed into the public sanitary sewer at any time. (See § 52.08(A), violations of policy.)
(C) Waste oil disposal. All establishments shall use waste oil barrels or containers to dispose of waste fats, oil and grease. Such material shall be recycled or disposed of through an establishment permitted and authorized to receive such waste in accordance with all applicable federal, state and local regulations.
(D) Compliance requirements.
(1) Establishments shall comply with the milestone dates of FOG discharge permits.
(2) Establishments not in compliance with the cleaning requirements of the FOG policy shall clean the grease interceptor within ten business days after the date the establishment receives written notice from the utility.
