Chapter 5 Fats, Oils, And Grease Disposal Regulations
18-504 : Grease interceptor/trap maintenance.
The user, at the user's expense; shall properly operate and maintain all grease interceptors/traps. Maintenance of grease interceptors/traps shall include the complete removal of all contents, including floating materials, wastewater and bottom sludge and solids. Decanting or discharging of removed waste back into the interceptor from which the waste was removed or any other grease interceptor/trap, for the purpose of reducing the volume to be disposed, is prohibited. No de-watering or surface skimming trucks are allowed to service grease interceptors. No steam cleaners or pressure washers may be used until the tank is pumped dry and then they may be used to clean the tank walls. It is the responsibility of each establishment to ensure proper pumping, maintenance and record keeping.
"Under the sink" grease interceptors must be cleaned no less than weekly. If grease traps are more than fifty percent (50%) full when cleaned weekly, the frequency shall be increased. Grease interceptors must be pumped out completely a minimum of once every three (3) months or more frequently as needed to prevent carryover of grease into the sanitary sewer collection system, unless it can be demonstrated to JCSCD that the pumping frequency can be extended past the three (3) month period.
All waste removed from each grease interceptor/trap must be disposed of at an establishment approved by JCSCD to receive such 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.
The JCSCD prohibits the introduction of chemicals, degreasers, acidic or caustic substances or any drain line additives that emulsify or otherwise temporarily dissolve fats, oils and grease to the extent it later solidifies in the JCSCD's sewer lines, pump stations or treatment plants. The following types of substances are prohibited from being used in floor drains, sinks or any other collection line that discharges to the grease interceptor:
Enzymes, spore-forming bacteria, chlorine bleach, emulsifiers, surfactants (soaps), industrial strength degreasers, acidic chemicals or cleaners, caustic chemicals or cleaners, solvents, citrus oils/cleaners for odors, sodium nitrate and/or substances with high flammability.
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.
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 establishment. A copy of the manifest must be provided to the JCSCD within seven (7) days of pumping. The customer is required to utilize only JCSCD permitted haulers for the disposal of grease.
A grease tank cleaning record/maintenance record indicating each pumping for the previous twenty-four (24) months shall be maintained by each food service establishment. This record shall include the date, time, amount pumped, hauler and disposal site and shall be kept in a conspicuous location for inspection. Said record shall be made immediately available to the JCSCD representative upon request. (as added by Ord. #2008-10, Aug. 2008)
