(1) The owner of every newly constructed, remodeled or converted commercial or industrial facility with one or more grease-generating activities, including food service facilities with new or remodeled kitchens, shall install or cause to be installed a grease interceptor for each grease-generating activity. Grease interceptors shall be sized, designed, constructed and installed in accordance with the Uniform Plumbing Code (UPC) standards, and any other requirements set by the Director through the City plan review and permit process.

(2) The owner of every commercial or industrial facility with one or more grease-generating activities, including food service facilities, serviced by a sewer connection line found to have a grease blockage, a history of grease blockage, or accelerated line maintenance resulting from grease disposal shall install or cause to be installed, upon notification by the Director, an approved grease interceptor.

(3) Grease interceptors shall be located outside the building in order to facilitate cleaning, inspection, and maintenance. Installation of smaller grease traps or grease interceptors located inside any building will be allowed only under circumstances where exterior installation is not effective or not practicable, and shall be approved only on a case-by-case basis.

(4) The owner of any facility with a grease interceptor installation shall maintain the grease interceptor at all times in a manner that shall prevent fat, waste, oil or grease from being carried into the sewer system. Authorized City employees shall be allowed access to grease interceptors for the purpose of inspection and/or to verify compliance with this chapter.
