Fats, oils and grease (FOG) and sand interceptors shall be provided when, in the opinion of the Director, they are necessary for the proper handling of liquid wastes containing fats, oils or grease discharges in which the concentration in a grab sample exceeds the 100 mg/l limit, or any flammable wastes, sand, or other harmful ingredients; except that such interceptors shall not be required for single-family or multiple-family dwelling units. All interceptors shall be of a type and capacity approved by the Director and shall be located as to be readily and easily accessible for cleaning and inspection. Grease and oil interceptors shall be constructed of impervious materials capable of withstanding abrupt and extreme changes in temperature. They shall be of substantial construction, water-tight and equipped with easily removable covers which when bolted into place shall be gas-tight and water-tight. When installed, all fats, oils, and grease, and sand interceptors shall be maintained by the owner, at his or her expense, in continuously efficient operation at all times. A user may petition the Director for an exemption from having to install a fats, oils and grease (FOG) interceptor in accordance with provisions specified in the YCUA FOG mitigation program policy, as amended from time to time. Upon approval by the Director, YCUA’s contract communities that have a fats, oils and grease ordinance/policy can implement the ordinance/policy in lieu of this section and the YCUA fats, oils and grease mitigation program policy.
