For the purpose of this subchapter, the following definitions shall apply unless the context clearly indicates or requires a different meaning.
COOKING ESTABLISHMENTS. Those establishments primarily engaged in activities of preparing, serving or otherwise making available for consumption foodstuff and that use one or more of the following preparation activities: cooking by frying (all methods), baking (all methods), grilling, sauteing, rotisserie cooking, broillng (all methods), blanching, roasting, toasting or poaching. Also included are infrared heating, searing, barbecuing, and any other food preparation activity that produces a hot, non-drinkable food product in or on a receptacle that requires washing.
FATS, OILS, AND GREASES. Organic polar compounds derived from animal and/or plant sources that contain multiple carbon chain triglyceride molecules. These substances are detectable and measurable using analytical test procedures established by 40 C.F.R. 136 (Federal Register), as may be amended from time to time. All are sometimes referred to herein as “Grease” or “Greases.”
GREASE TRAP INTERCEPTOR. A device for separating and retaining waterborne greases and grease complexes prior to wastewater exiting the trap and entering the sanitary sewer collection and treatment system. These devices also serve to collect settable solids, generated by and from food preparation activities, prior to the water exiting the trap and entering the sanitary sewer collection and treatment system. Grease Traps and interceptors are sometimes referred to herein as “Grease Interceptors.”
USER. Any person or company, including those located outside the jurisdictional limits of the town, who contributes, causes, or permits the contribution or discharge of wastewater into the sanitary sewer system.
VEHICLE MAINTENANCE FACILITY. Any commercial or industrial facility where automobiles, trucks or equipment are serviced or maintained, including garages, service stations, repair shops, oil lubrication shops, or similar establishments.
(Ord. passed 2-23-2009)
(A) No later than 1 year after adoption of this subchapter, all users shall install grease traps or interceptors designed to limit the introduction, contribution and discharge of greases into the town’s wastewater collection system or POTW. Grease traps and interceptors with appropriate sampling or inspection points shall be installed at the user’s expense whenever any user operates a commercial establishment, industrial establishment, or a cooking establishment. Grease traps and interceptors must have a minimum capacity of 1,000 gallons. No user shall allow wastewater discharge concentration from subject grease interceptor to exceed 200 mg/l (milligrams per liter), as identified by EPA Method 1664.
(B) Alternative methods of compliance by existing establishments may be approved by the town if the user demonstrates that compliance with this subchapter is impossible or impractical at the time of adoption of this subchapter as a result of limited space, production of waste grease, and taking into account the circumstances of the business’s operation. However, any such proposed alternative method of compliance will be required to meet the performance criteria specified in division (A) of this section, and the user must adequately demonstrate to the satisfaction of the town that the proposed alternative method will satisfy those performance criteria. In addition, any such alternative method must be cleaned at a more frequent interval than is required of grease traps and interceptors under § 53.79(A). Prior to approval of any such proposed alternative method of compliance, documentation of the proposed method’s actual performance criteria must be submitted to the town’s Public Works Director and/or Town Manager for review and approval.
(C) Grease traps and interceptors may also be required in other facilities such as schools, service stations, car washes, vehicle repair and lubrication facilities, nursing homes and any other facility that handles grease and which discharges wastewater containing grease into the town sewer collection system.
(D) Existing establishments with an existing grease interception system that does not meet the standards may be required to upgrade the system or may be allowed to continue use of the present system subject to requirements such as a clean-out frequency less than 90 days.
(Ord. passed 2-23-2009) Penalty, see § 53.99
Upon prior written approval of the Public Works Director, establishments may be exempted from the requirements of this subchapter after an inspection of the subject premises and submission of adequate supporting documentation, as deemed necessary in the sole and absolute discretion of the Public Works Director and/or Town Manager. At a minimum, such supporting documentation shall include: blueprints of the subject premises, a full and detailed description of the operations and activities at the subject premises, and a full and detailed list of all potential sources of grease at the subject premises. Any exemption may be subject to revocation as a result of change in operations and/or activities at the subject establishment.
(Ord. passed 2-23-2009)
(A) Users shall empty and service grease traps and interceptors to comply with the performance criteria in § 53.77(A) and (B) as often as necessary, but in any event no longer than 90 days. Under-the-counter types of grease traps and interceptors shall be cleaned at least daily, and shall comply with the performance criteria in § 53.77(A). There shall be no reintroduction of wastewater back into the grease trap or interceptor unless and until said wastewater has been proven to contain 200 mg/l or less grease. Under no circumstances shall the sludge or scum layer be reintroduced or discharged into the town’s wastewater collection system or POTW.
(B) Users shall supply (a) an adequate sampling point downstream of the grease trap or interceptor prior to mixing with other sanitary flows, and (b) an accessible entry into each chamber of the grease trap or interceptor. The minimum requirement for the sampling point shall be a 4-inch vertical clean-out.
(C) Users are required to keep the grease trap or interceptor free of inorganic solids such as grit, towels, gloves, cigarettes, eating utensils, etc., which would clog or settle in the trap or interceptor, thereby reducing the effective volume or capacity of the trap or interceptor.
(Ord. passed 2-23-2009) Penalty, see § 53.99
Users shall retain detailed records on-site for a minimum of 3 years reflecting all maintenance performed under this subchapter. At a minimum, such records shall contain the following information: date of service, name of the employee involved, and a receipt reflecting all services rendered by the waste hauler providing the service.
(Ord. passed 2-23-2009) Penalty, see § 53.99
Users are required to ensure that all waste material removed from the grease traps and interceptors is disposed of in a manner that complies with all federal, state, and local statutes, rules, regulations, policies, and ordinances.
(Ord. passed 2-23-2009) Penalty, see § 53.99
(A) The Public Works Director (or his or her designee) will conduct a minimum of 1 compliance inspection annually, based on compliance history, collection system problems, etc. Except as provided herein, for a period of 1 year following the adoption of this subchapter, no enforcement actions will be taken for failure to achieve the performance criteria specified in § 53.77.
(B) Failure to service the grease trap or interceptor in the time period required and/or failure to provide required documentation shall each constitute a violation of this subchapter. Users who continue to violate this subchapter may be subject to discontinuance of water service. The town may assess surcharges or penalties as specified in the town sewer use ordinance.
(C) If an obstruction of any of the town’s sanitary sewer main(s) occurs and causes a sewer overflow, spill, leak, or other event with any environmental impact, and the event can be attributed in part or in whole to a particular user, then the town will seek enforcement action under the sewer use ordinance and/or the pretreatment enforcement plan.
