Section 29-5 entitled, "Fat, oil and grease control", of Article I of Chapter 29 of the City Code, reading as follows : Sec. 29-5 . - Fat, oil, and grease control . (a) Scope and purposes. The objective of this section is to aid in preventing the introduction and accumulation of fats, oils, and greases into the municipal wastewater system which will or tend to cause or contribute to sanitary sewer blockages and obstructions . Food service establishments and other industrial, institutional or commercial establishments generating wastewater containing fats, oils or greases are subject to this section. This section regulates such users by requiring that grease interceptors and other approved strategies be installed, implemented, and maintained in accordance with the provisions hereof. Existing grease traps or interceptors that are in good repair and functioning properly may be exempt from grease trap location requirements until such time that the establishment changes ownership, undergoes a major remodel, change of purpose, or fails to meet discharge action levels . (b) Grease interceptor installation, inspection, maintenance, record-keeping, and grease removal . (1) Grease interceptors shall be installed and maintained at the user' s expense, when a user operates a food service establishment . Grease interceptors may be required in noncooking or cold dairy and frozen foodstuffs establishments and other industrial or commercial establishments when the establishment generates wastewater containing fat or grease and the public works director or his designee determines an interceptor is necessary to prevent contribution or accumulation of grease to the sanitary sewer collection and treatment system. No user shall allow wastewater discharge concentration from subject grease interceptor to exceed an established action level of one hundred (100) milligrams per liter, expressed as hexane extractable material . Any user in violation of these limits shall be subject to penalties as set out in this article. All grease interceptors shall be of a type, design, and capacity approved by the public works director or his designee and shall be readily and easily accessible for maintenance and repair, including cleaning and for inspection. All grease interceptors shall be serviced and emptied of accumulated waste content as required in order to maintain minimum design capability or effective volume of the grease interceptor, but not less often than every sixty (60) days or as permitted in a valid program modification. Users who are required to pass wastewater through a grease interceptor shall: a. Provide for a minimum hydraulic retention time of twenty-four (24) minutes at actual peak flow between the influent and effluent baffles, with twenty-five (25) percent of the total volume of the grease interceptor being allowed for any food-derived solids to settle or accumulate and floatable grease-derived materials to rise and accumulate, identified hereafter as a solids blanket and grease cap respectively. b. Remove any accumulated grease cap and solids blanket as required, but at intervals of not longer than sixty (60) days at the user' s expense, or in accordance with a valid program modification or other public works director or his designee ' s requirements . Grease interceptors shall be kept free of inorganic solid materials, such as grit, rocks, gravel, sand, eating utensils, styrofoam, cigarettes, shells, towels, rags, etc. , which could settle into this solids blanket and thereby reduce the effective volume of the grease interceptor. c. Operate and maintain the grease interceptor to achieve and maintain any applicable grease action level . This shall mean any wastewater sample taken from such grease interceptor must meet the terms of numerical limit attainment described in section 29-5 (b) (1) . d. If a user documents that conditions exist ("space constraints") on their establishment site that limit the ability to locate a grease interceptor on the exterior of the establishment, the user may request an interior location for the interceptor. Such request shall contain the following information: 1 . Location of city sewer main and easement in relation to available exterior space outside building. 2 . Existing plumbing layout at or in a site. 3 . A statement of understanding, signed by the user or authorized agent, acknowledging and accepting conditions the public works director or his designee may place on permitting an identified interior location. Conditions may include requirements to use alternative mechanisms, devices, procedures, or operations relative to an interior location. 4 . Grant of access to interceptor for city inspection. 5 . Such other information as may be required by the public works director or his designee. e. The use of biological or other additives as a grease degradation or conditioning agent is not permissible. f. The use of automatic grease removal systems is permissible only upon prior written approval of the public works director or his designee and the Cape Girardeau County Public Health Center Director or designee. Any user using a grease interceptor located on the interior of the site shall be subject to any operational requirements set forth by the City of Cape Girardeau. Any user using this equipment shall operate the system in such a manner that attainment of the grease wastewater discharge limit, as measured from the unit ' s outlet, is achieved as required by the public works director or his designee. g. The public works director or his designee may make determinations of grease interceptor adequacy need, design, appropriateness, application, location, modification (s) , and conditional usage based on review of all relevant information regarding grease interceptor performance, facility site and building plan review by all regulatory reviewing agencies and may require repairs to, or modification or replacement of grease interceptors . h. The user shall allow access to the public works director or his designee for the purpose of determining compliance with this article. (2) The user shall maintain a written record of grease interceptor maintenance for three (3) years . All such records will be available for inspection at all times . These records shall include: a. FSE name and physical location; b. Date of grease interceptor service; c. Time of grease interceptor service; d. Name of grease interceptor service company; e. Name and signature of grease interceptor service company agent performing said service; f. Established service frequency and type of service; g. Number and size of each grease interceptor serviced at FSE location; h.
