Section 4.4.3  Fat, Oil and Grease (FOG) Prohibited (8/5/10)

(a) The accumulation of fats, oils and greases (hereinafter “FOG”) in the sewer collection and treatment system increases the risks of sewer main blockages, pump station failures, lateral blockages, and customer backups, all of which drive up operational costs and create public health and safety risks.
(b) Property owners shall make all  reasonable attempts to eliminate or minimize the discharge of FOG into the sewer collection system.
(c) Food scraps should be placed in the solid waste or garbage system rather than in the sewer system, and all used oils and greases should be deposited into designated recycling or disposal collection systems other than the sewer system.
(d) All operators of commercial or institutional establishments, including, but not limited to, schools, hospitals, restaurants, markets, grocery stores, or other such commercial or manufacturing operations where broiling, boiling, roasting, frying, baking, rendering, grilling and other forms of cooking take place, are required to install and maintain a properly operating combination of grease traps and/or interceptors which are sufficiently sized, engineered, designed and installed to reduce the FOG effluent level to less than 100 parts per million of FOG, measured as Hexane Extractable Material (HEM).
(e) All exterior grease interceptors must be cleaned per manufacturer’s recommendations, but not less than once every 60 days, and more frequently if deemed necessary by the Authority.
(f) All interior grease traps must be cleaned per manufacturer or Health Department recommendations, but no less than once every 30 days and more frequently if deemed necessary by the Authority.
(g) Grease trap and grease interceptor cleaning records must be kept for at least 3 years and made available for immediate inspection by the Authority representatives during business operating hours.
(h) Sewer lateral effluent line sampling locations shall be installed at the - 24 -property owner’s expense at designated locations if required by the Authority representatives, and shall be made available for sampling and inspection during regular business hours.
(i) Exiting water temperature should not exceed 120-degrees Fahrenheit to avoid liquefied fats, oils or greases from flowing passed the trap or interceptor and resulting in   damages to the sewer system.
(j) Accumulated grease thickness should never exceed 6” on the walls, baffles or along the bottom of grease traps or interceptors.
(k) To prevent damage to the Authority sewer system, Authority representatives may annually or more often if found to be needed, inspect any grease trap and/or grease interceptor.  If directed by the Authority representative, the property owner shall have performed a grease trap and/or grease interceptor cleaning by a qualified vendor, and the owner shall coordinate such cleaning for a time the Authority representative may be on-site to inspect the unit.
(l) Maintenance, repair or replacement costs, and cost of a sewer overflow, related to excessive grease in the Authority sewer system, and traceable to the food service operations of a specific facility or residence, shall be paid by and the responsibility of the user, and shall be reimbursed to the Authority within 30 days of billing, and failure to pay shall constitute a violation of the Rules and Regulations.
(m) Any fine, penalty or assessment imposed on the Authority by the State of Mississippi or the United States of America in connection with a sanitary sewer overflow which is related to excessive grease in the Authority sewer system, and traceable to the food service operations of a specific facility or residence, shall be paid by and the responsibility of the user, and shall be reimbursed to the Authority within 30 days of billing, and failure to pay shall constitute a violation of the Rules and Regulations.
(n) Any property owner that violates the FOG Rules and Regulations of the Authority will be issued a written notice of violation with a maximum time of 15 days to resolve and correct the noted deficiencies.  For any failure to resolve and correct the deficiencies within 15 days following notice of violation, the Authority may, in addition to all other penalties, assessments and remedies, assess a penalty to up to $100.00 per day thereafter for the continuing violation until the deficiencies have been resolved and corrected.
