(A) No later than one year after the adoption of this chapter, all non-residential users with potential grease producing operations 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. This requirement includes all cooking establishments and any other commercial or industrial establishment that exceeds the allowable grease concentration of this section. Grease traps and interceptors with appropriate sampling or inspection points shall be installed at the user's expense whenever a grease trap or interceptor is required to be installed as in division (F) of this section. Grease traps and interceptors must have a minimum capacity of 1,000 gallons or more as required to effect a grease concentration maximum of 200 mg/l.
(B) The town may approve alternative methods of compliance if the user demonstrates that compliance with this chapter is impossible or impractical at the time of adoption of this chapter as a result of limited space. However, any 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 alternative method must be cleaned at a more frequent interval than is required of grease traps and interceptors under division (E) of this section. Prior to approval of any proposed alternative method of compliance, documentation of the proposed method's actual performance criteria must be submitted to the Public Works Director for review and approval.
(C) Grease traps and interceptors may also be required in other facilities as deemed necessary by the Public Works Director.
(D) Upon the prior written approval of the Public Works Director, non-cooking establishments may be exempted from the requirements of this chapter 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. 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.
(E) Users shall empty and service grease traps and interceptors to comply with the performance criteria in division (A) as often as necessary, but in any event no longer than every 60 days. Under-the-counter types of grease traps and interceptors shall be cleaned at least daily, and shall comply with the performance criteria in division (A) of this section. There shall be no reintroduction of wastewater back into the grease trap or interceptor unless and until the wastewater has been proven to contain 200 mg/l or less of grease. Under no circumstances shall the sludge or scum layer be reintroduced or discharge into the town's wastewater collection system or POTW.
(F) Users shall supply an adequate sampling point downstream of the grease trap or interceptor, prior to mixing with other sanitary flows, and an accessible entry into each chamber of the grease trap or interceptor. The minimum requirement for the sampling point shall be a four-inch vertical clean-out.
(G) Users shall retain detailed records on-site for a minimum of three years reflecting all maintenance carried out pursuant to this chapter. 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 water hauler providing the service.
(H) Users are required to keep the grease trap or interceptor free of inorganic solids such as grit, towels, gloves, cigarettes, eating utensils, and the like, which could clog or settle in the trap or interceptor, thereby reducing the effective volume or capacity of the trap or interceptor.
(I) Users are required to ensure that all waste material removed from grease traps and interceptors is disposed of in a manner that complies with all federal, state, and local statutes, rules, regulations, policies and ordinances.
(J) Except as provided herein, for a period of one year following the adoption of this chapter, no enforcement actions will be taken under this section for failure to achieve the performance criteria specified in division (A). If, during such period, 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 such overflow, spill, leak or other event may be attributed in part or in whole to a particular user, then the town will seek enforcement action and possible penalties under §§ 53.04 and 53.99. For purposes of this section, an overflow, spill, leak or other event shall be deemed to have an environmental impact when such overflow or other event involves an amount of wastewater equal to or in excess of 1,000 gallons or an amount of wastewater reaches any body of surface water.
