   GARAGE: Establishments that service, repair, wash or refurbish motor vehicles, farm equipment, construction equipment, aircraft, tractors and trailers and the like.
   GREASE INTERCEPTOR: A device that is designed in accordance with the uniform plumbing code, appendix H, and installed in such a manner as to separate and retain grease that is produced in food preparation and serving areas, and, at the same time, permitting normal sewage to be discharged into the system.
   INSPECTOR: The person designated by the city to inspect grease interceptors for proper construction, installation, operation, and maintenance.
   PUMPER: A qualified person or firm who has a city business license to remove and dispose of grease. (1973 Code § 13.44.010)
   B.   Grease, Sand/Oil Interceptors Required: Auto or machinery wash racks, or floor or slab used for cleaning machinery, machine parts or autos shall drain or discharge into a grease interceptor. Grease interceptors will be required on all new construction commenced after the effective date hereof. All such structures, drains, or lines which utilize the city storm drains or waste water treatment facility shall comply with this section and that of the uniform plumbing code. (1973 Code § 13.44.020)
   C.   Grease Interceptor Required:
      1.   All food establishments producing grease or grease byproducts and introduce said grease into the sanitary sewer system within the city shall install an approved grease interceptor in accordance with the uniform plumbing code within one hundred eighty (180) days of the passage hereof. Each grease interceptor shall be so installed to be easily accessible for inspection by the city. The approved grease interceptor shall be designed and installed by a qualified firm having a city business license. Grease emulsifiers or enzymes are prohibited for use in grease interceptors. (1973 Code § 13.44.030; amd. 2001 Code)
      2.   If an existing grease interceptor or grease trap device that was legally or properly installed in an establishment prior to the effective date hereof is effective in removing grease and is designed and installed in such a manner that it can be inspected and properly maintained, then the requirement of a device conforming to the uniform plumbing code, appendix H, shall be waived by the city. However, if such existing grease interceptor or trap is incapable or becomes incapable of effectively retaining grease, the city shall issue a written notice that requires the owner/operator of such establishment to install the grease interceptor required by this section within one hundred eighty (180) days. (1973 Code § 13.44.030)
   D.   Inspections:
      1.   Accessibility: All grease interceptors/traps shall be readily accessible for inspection and shall be properly maintained to ensure that accumulations of grease do not impair the efficiency of the interceptor/trap or are not discharged with the effluent.
      2.   Required Records: Each establishment shall keep a record of every time the interceptor/trap is cleaned, which shall include the date, the name of the pumper, and such records shall be available to review by city authorities.
      3.   Improper Maintenance: Any interceptor/trap shall not be considered properly maintained if accumulation of grease totals more than twenty five percent (25%) of the interceptor/trap operative fluid capacity.
      4.   Periodic Inspections: Inspections will be made periodically by the city and without prior notice.
      5.   Notice Of Violation: If it is found that the interceptor/trap in any establishment is improperly maintained or required records are not being kept, a notice of violation will be issued to the operator. If, on any subsequent inspection, it is found that the aforesaid condition continues to exist, such violation shall constitute a misdemeanor. (1973 Code § 13.44.040)
   E.   Extension For Compliance: If, as a result of this section, an undue financial hardship can be demonstrated by an establishment, the city manager may, upon request of the establishment, extend the time to comply with this section, for an additional period of six (6) months. (1973 Code § 13.44.050)
