(A) Cleaning/pumping. The user at the user's expense shall maintain all grease traps and interceptors. Maintenance of "under the sink" grease traps shall include the removal of all fats, oil and grease from the detention compartment of the trap. Removal is usually accomplished by hand-dipping or scooping the collected grease from the trap. Maintenance of grease interceptors shall include the complete removal of all contents, including floating materials, wastewater and bottom sludges and solids. Decanting or discharging of removed waste back into the interceptor from which the waste was removed or any other grease interceptor, for the purpose of reducing the volume to be disposed, is prohibited.
(B) Cleaning/pumping frequency. "Under the sink" grease traps must be cleaned no less than weekly. If grease traps are more than 50% full when cleaned weekly, the frequency shall be increased. Grease interceptors must be pumped out completely a minimum of once every 90 days, or more frequently as needed to prevent carry over of grease into the sanitary sewer collection system, unless it can be demonstrated to the city that the pumping frequency can be extended past the 90-day period.
(C) Disposal of grease interceptor waste. All waste removed from each grease interceptor must be disposed of at a facility approved by the city to receive the waste in accordance with the provisions of this program. In no way shall the pumpage be returned to any private or public portion of the sanitary sewer collection system.
(D) Additives. Any additive(s) placed into the grease interceptor or building discharge line system on a constant, regular or scheduled basis shall be reported to the city. The additives shall include, but not be limited to, enzymes, commercially available bacteria or other additives designed to absorb, purge, consume, treat or otherwise eliminate fats, oil and grease. The use of additives shall, in no way, be considered as a substitution to the maintenance procedures required herein.
(E) Chemical treatment. Chemical treatments such as drain cleaners, acid and other chemicals designed to dissolve or remove grease shall not be allowed to enter the grease interceptor.
(F) Manifest. All pumpage from grease interceptors must be tracked by a manifest, which confirms pumping, hauling and disposal of waste. The customer must obtain a copy of the original manifest from the hauler. The original manifest with original signatures must be left at the disposal facility. The customer is required to utilize only city permitted haulers for the disposal of grease.
(G) Maintenance log. A grease interceptor cleaning record maintenance log indicating each pumping for the previous 24 months shall be maintained by each FSF. This log shall include the date, time, amount pumped, hauler and disposal site and shall be kept in a conspicuous location for inspection. The log shall be made immediately available to the city representative upon request. Reports detailing the pumpage manifest and grease interceptor data shall be mailed annually on provided forms to the following address: Veolia Water/Crossville Wastewater Plant 468 Sparta Highway Crossville, TN 38572.
