Section 13.12.320 Grease, oil and sand interceptors.
A. Grease, oil and sand interceptors shall be provided for all establishments
processing and
handling food including restaurants and including all other persons or establishments when, in
the opinion of the director of public works, necessary for the proper handling of wastes
containing grease, or any flammable wastes, sand or other harmful ingredients.
B. All interceptors shall be of a type and capacity approved by the director
of public works, and
shall be located and be readily and easily accessible for cleaning and inspection. Grease and oil
interceptors shall be constructed of impervious non-corrosive materials capable of withstanding abrupt
and extreme changes in temperature. They shall be of substantial construction, watertight, and
equipped with easily removable covers which when bolted in place shall be gastight and
watertight.
C. Small capacity "grease trap" devices are not allowed. A small capacity
grease trap shall not
be considered as a substitute of a full capacity grease interceptor unless the physical installation
of a full capacity grease interceptor is physically not possible, as determined by the director of
public works. If the director of public works determines a grease interceptor cannot be installed,
the director of public works may grant a waiver and allow the use of a small capacity grease trap.
A written agreement shall be provided by the owner of the property that allows inspection of the
grease trap by the director of public works, or his/her agent. Such agreement shall include a
guarantee to maintain the grease trap and not allow contraband material to discharge into the
public sewer system. Violation of any part of the written agreement shall result in the city revoking
the agreement and require immediate installation of a full capacity grease interceptor. (Ord. 215 (part),
