Section 16-43 (2)

• Any water or waste containing nonemulsified fats, wax, grease or oils, in excess of one hundred (100) mg/l or containing substances which may solidify of become viscous at temperatures between thirty-two (32) degrees and one hundred fifty (150) degrees Fahrenheit.

• (a) Grease and oil interceptors shall be provided as stipulated in section (d) below or when liquid wastes contain an excess of one hundred (100)mg/l of grease or contain substances which may solidify or become viscous at temperatures between thirty-two degrees Fahrenheit (32° F) or zero degrees Centigrade (0° C) and one hundred fifty degrees Fahrenheit (150°F) or sixty-five degrees Centigrade (65°C), except that such interceptors shall not be required for single family homes or multifamily dwelling units unless problems occur at particular locations more than twice in 12 month period.
• (b) Grease interceptors to be installed shall be in conformance with the most recent Lexington-Fayette Urban County Government Sanitary Sewer and Pumping Station Manual, The State Plumbing Code and the applicable Lexington-Fayette Urban County Government standard Drawing. The required interceptor shall be designed according to the most stringent of the above current standards and approval of the interceptor shall be determined by the Lexington-Fayette Urban County Government Division of Engineering upon review of the proposed facility and sized according requirements of the Lexington-Fayette Urban County Government Sanitary Sewer and Pumping Station Manual to the manufacturer's recommendations. The interceptor shall be located so as to be readily and easily accessible for cleaning and inspection. Grease and oil interceptors shall be cleaned on a regular basis as specified by the interceptor manufacturer based on size of the facility and type of food served, whichever is the most stringent.
• (c) Grease and oil interceptors shall be constructed of impervious materials capable of withstanding abrupt and extreme changes in temperatures. They shall be of substantial construction, watertight and equipped with easily removable covers which, when bolted in place shall be gastight and watertight. Each user shall provide protection against accidental discharge of grease and oil. Features which prevent accidental discharge of these material shall be provided and maintained at the users expense. Facilities and operating procedures to provide this protection shall be submitted to the New development Section of the Division of Engineering for review and approval prior to construction of the facility. Review and approval of such plans and operating procedures by the New development Section shall not relieve the user of the responsibility to modify its facility as necessary to meet the requirements of this Chapter.
• (d) Grease and oil interceptors shall be required at all facilities which provide food service and/or preparation activities, including, but not limited to, full service restaurants, fast food establishments, delis, cafeterias (including church and school facilities where commercial equipment is installed and the square footage and/or frequency of use indicates more than occasional use), meat distributors, food processing facilities, grocery stores with food preparation/service areas, bakeries, caterers, and/or other similar types of operations.
• (e) A food service and or preparation facility which demonstrates that the discharge from its food service and/or preparation activities contains less than 100 mg/l of grease, may receive an exemption from minimum sizing requirements or installation and maintenance requirements. The sampling and testing to demonstrate the concentration of grease in the discharge must be conducted, at the facility’s expense, by an independent testing organization and measured in accordance with the analytical test procedures established in 40 CFR 136 as amended from time to time.
• (f) Grease and oil interceptors shall be cleaned on a regular basis which will ensure proper and efficient operation but not less than one time within a six month period. Approved internal or under-counter interceptors shall be cleaned at least once per week. Cleaning shall consist of removal of the entire contents of the divice, including grease cap and sludge pocket, and inspection of the empty device for defects and/or obstructions which would prevent proper function.
• (g) Written records shall be maintained by the user indicating maintenance and cleaning of the grease interceptor. The record shall indicate: dates of maintenance; person performing maintenance; estimated volume of grease removed; receipts or manifest from haulers; disposal locations; facility manager’s verification. The records shall be retained for a period of three years and shall be available at the facility along with a copy of the grease interceptor permit for inspection by the Division of Sanitary Sewers.

• (c)Any person violation any of the provisions of Section 16-36 through 16-71 shall become liable to the Urban County Government for any expense, loss or damage occasioned by the Urban County Government by reason of such violation. Said person shall also be liable for repairing or restoring any sanitary sewer, storm sewer and natural outlet damaged, obstructed or impaired by such violation to its pre-existing condition.
