<br />. <br /> <br />The FOG Control Program Manager may provide a written waiver to the <br />requirement to install a grease interceptor, listing the conditions upon <br />which said waiver is granted, upon a finding of one or more of the <br />following: <br /> <br />(1) The FSE can substantively demonstrate that it employs an <br />alternative pretreatment technology that is equivalent or better than a <br />grease interceptor in controlling its FOG discharge, <br /> <br />(2) The FSE provides evidence through downstream visual <br />monitoring of the sewer system for at least three months, at its own <br />expense, that no visible accumulation of FOG in its lateral and/or tributary <br />downstream sewer lines is occurring. <br /> <br />(3) There is no potential for FOG from the FSEs to cause or <br />contribute to SSOs. <br /> <br />. <br /> <br />(4) The FSE discharges of FOG are negligible and do not cause a <br />significant impact to the sewer system. <br /> <br />(5) The FSE pays a Grease Cleaning Fee in lieu of installation of a <br />grease interceptor. This cleaning fee can be paid in lieu of installation of a <br />grease interceptor when: (1) installation of an interceptor can not <br />physically be accomplished, (2) there is not adequate slope for gravity flow <br />between kitchen plumbing fixtures and the grease interceptor and/or <br />between the grease interceptor and the private collection lines or the <br />public sewer and (3) no alternative pretreatment can be installed. Further, <br />the FSE must agree to either (a) hire a contractor to clean and inspect the <br />sewer main as established in Rules and Regulations or (b) pay a yearly <br />fee (Grease Cleaning Fee) to the City for the increased cost to clean the <br />sewer mains. The Grease Cleaning Fee shall be established by resolution <br />of the City Council, and shall be based on the estimated annual increased <br />cost of maintaining the sewer system for inspection and removal of FOG <br />and other viscous or solidifying agents attributable to the FSE resulting <br />from the lack of a grease interceptor or grease control device. <br /> <br />. <br /> <br />(6) The FSE may use or may be required to install grease traps, in <br />lieu of installation of a grease interceptor when (1) installation of an <br />interceptor can not physically be accomplished, (2) there is not adequate <br />slope for gravity flow between kitchen plumbing fixtures and the grease <br />interceptor and/or between the grease interceptor and the private <br />collection lines or the public sewer and (3) no alternative pretreatment can <br />be installed. Sizing and installation of grease traps shall conform to the <br />current edition of the California Plumbing Code. Grease traps shall be <br />maintained in efficient operating conditions by periodic removal of their full <br />content, including sewage, FOG, floating materials, sludge and solids.
