(A) Application of requirements. The requirements of this section shall apply to:
(1) All new food service establishments including, but not limited to, restaurants, cafeterias, hotels, motels, hospitals, nursing homes, schools, grocery stores, caterers, manufacturing plants and any other dischargers who introduce FOG into the sanitary sewer;
(2) Any existing food service establishment upon the sale or transfer of operational control thereof;
(3) Any existing food service establishment upon renovation of the plumbing system or addition of any equipment that may increase discharge of FOG to the sewer system, regardless of valuation; or any material renovation of the establishment with a building permit valuation of $50,000 or more; and
(4) Any existing food service establishment, which has caused or contributed to a grease-related blockage in the sanitary sewer, or which, based on inspection or sampling, has been determined by the Director to be discharging FOG in significant quantities sufficient to adversely impact the sanitary sewer.
(B) Grease interceptor requirement. All food service establishments specified in division (A) of this section shall install, operate and maintain an approved type, adequately sized and readily accessible grease interceptor necessary to maintain compliance with the requirements of this chapter. Grease interceptor sizing and installation shall meet the minimum standards of the most recent edition of the California Plumbing Code. Grease interceptors shall have a minimum of two compartments with fittings designed for grease retention and shall be constructed and installed in accordance with the San Gabriel Municipal Code, subject to the review and approval of the Director and the Building Official.
(C) Variance of grease interceptor requirement. A food service establishment may obtain a variance from the grease interceptor requirement, if a request is submitted in writing to the Director, to allow the installation and maintenance of an alternative pretreatment device in lieu of a grease interceptor provided that such alternative pretreatment device is equally as effective in controlling the FOG discharge. Alternative pretreatment devices, including, but not limited to, grease traps and other separation and holding devices, must be appropriately sized and approved by the Director and the Building Official. The food service establishment must demonstrate to the satisfaction of the Director that the grease interceptor installation and operation is physically not feasible or not warranted to fulfill discharge requirements at the site and that the alternative pretreatment device is equivalent to a grease interceptor in controlling the food service establishment’s FOG discharge.
(D) Conditional waiver of interceptor requirement. An existing food service establishment may obtain a conditional waiver from installing a grease interceptor if the food service establishment can demonstrate to the satisfaction of the Director that it has a negligible FOG discharge and an insignificant impact on the sewer system. Any waiver granted by the Director shall be voided by the food service establishment making changes in its operations that significantly affect FOG discharge, including, but not limited to, changes in food preparation activities, renovations of the plumbing system, and increased discharges to the sewer system. The waiver shall remain valid until the expiration date specified in the waiver, provided that the food service establishment remains in compliance with the waiver’s terms and conditions. A waiver may be revoked at any time when any of the terms and conditions for its issuance is not satisfied or if the justification for the waiver no longer exists.
(E) Sanitary fixtures. Toilets, urinals, and other similar sanitary fixtures shall not discharge through the grease interceptor unless specifically approved, in writing, by the Director.
