(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.
