All grease trap/interceptors shall be installed in compliance with any pertinent County Health District Guidelines along with city guidelines, state and federal codes.
(A) New or expanded facilities. Food processing facilities, food service facilities or multi-dwelling units which are newly proposed or constructed, or existing facilities which will be expanded or renovated to include a food service facility, (where such facility did not previously exist), shall be required to design, install, operate and maintain a grease trap/interceptor in accordance with locally adopted plumbing codes or other applicable ordinances. Grease traps/interceptors shall be installed and inspected by the POTW prior to issuance of a certificate of occupancy.
(B) Existing facilities. Existing grease traps/interceptors must be operated and maintained in accordance with the manufacturer’s recommendations and in accordance with these model standards, unless specified in writing and approved by the POTW.
(C) Sampling port. All new and renovated food preparation facilities shall construct adequate sampling port at each grease trap. Ideally, the sampling port shall be a specifically designed exterior structure, constructed on the effluent pipe of the trap. This structure shall result in a free-falling liquid, so that a sample bottle can be held under the flow to capture a sample. FOG samples should represent the worst case scenario. The worst case scenario (peak flow) is the point at which FOG removal equipment is most likely to fail, and FOG loading of the collection system will occur. The goal of the equipment is to remove FOG even at peak flow; therefore, sampling needs to occur at peak flow to ensure that the equipment is adequate. Frequency of sampling is determined by the need for data. When setting a monitoring schedule to ensure that FOG or temperature limits are being met, and the compliance history of each facility (the number of blockages or other problems caused by the facility, how often the facility pumps out its grease trap or cleans its interceptor). FOG sampling may be scheduled and sampled by the POTW as part of compliance monitoring on an unannounced basis. The POTW will send samples to an approved laboratory. Cost for all FOG testing ordered by the POTW shall be the responsibility of the establishment. All test results shall be available to the establishment.
