a.A food service establishment or any other business discharging fats, oil, and grease, or other similar material, shall have an operable grease trap, grease interceptor or other comparable device(s) as determined by MRWPCA, the City Engineer, and/or the City’s Chief of Inspection Services/Building Official to be an adequate substitute for a grease trap or grease interceptor. A properly sized interceptor or trap shall be considered first, in conformity with the sizing matrix set forth by the MRWPCA. Should space limitations or other exceptional circumstances prevent their installation, the City may grant waivers to the requirement for grease interceptors in this section.

b.All drains from food preparation and cleanup areas including, but not limited to, pre-wash sinks, floor drains, pots and pans sinks, scullery sinks, dishwashers and garbage can wash areas shall be connected to such interceptor. Food waste disposal units are only allowed where a grease interceptor has been installed and must be connected to that interceptor.

c. Sizing Formula.The size of a grease trap or grease interceptor shall be as determined by the MRWPCA. Notwithstanding the foregoing, grease traps required by this chapter shall be no smaller than an 80-gallon liquid capacity trap unless otherwise approved by the Chief of Inspection Services/Building Official.
