(2) A FSE may use, or be required to install, grease traps, in lieu of installation of a grease interceptor, when, in the opinion of the manager: 1) installation of an interceptor cannot physically be accomplished; 2) there is not adequate slope for gravity flow between kitchen plumbing fixtures and a proposed grease interceptor and/or between the grease interceptor and the private collection lines or the public sewer; or 3) no alternative pretreatment can be installed. Sizing of grease traps shall be performed by a professional engineer or plumber registered in the State of Utah, but shall conform to SGRWRF Design Standards and Construction Specifications as a minimum.
(3) Grease traps shall be operated in accordance with the manufacturer's specifications.
(4) Grease traps shall be maintained in efficient operating condition by removing accumulated grease on an as needed basis, or the frequency specified by the manufacturer, but no less than weekly.
(5) Grease traps shall be fully emptied of all food residues, and any FOG waste, during the cleaning and scraping process.
(6) Grease traps shall be inspected periodically, but in no event less than once a month, to check for leaking seams and pipes, and for effective operation of the baffles and flow-regulating device. Grease traps and their baffles shall be maintained free of all caked-on FOG and waste. Removable baffles shall be removed and cleaned during the maintenance process.
(7) Automatic dishwashers and/or food grinder units shall not be connected to, or discharged to, any grease trap.
(8) No FSE shall increase the use of water or in any other manner attempt to dilute a discharge as a way of achieving compliance with the St. George Pretreatment Ordinance. (Ord. 2018-19, 2018)
