<br />15.44.010 Scope and purpose.
<br />To aid in the prevention of sanitary sewer block-
<br />ages and obstructions from contributions and accumula-
<br />tion of fats, oils and greases into the sanitary sewer sys-
<br />tem from any industrial or commercial establishments,
<br />particularly food preparation and serving facilities. The
<br />city of Pleasanton is committed to reduce sanitary sewer
<br />overflows that are harmful to the environment and costly
<br />to the rate payers in terms of increased maintenance and
<br />cleanup. Fats, oils and grease are a major contributor to
<br />this problem both locally and throughout California.

<br />amended by the city of Pleasanton's Municipal Code.
<br />B. "Fats, oils and greases" mean organic polar
<br />compounds derived from animal and/ or plant sources
<br />that contain multiple carbon chain triglyceride mole-
<br />cules. These substances are detectable and measurable
<br />using analytical test procedures established in the United
<br />States Code of Federal Regulations 40 CFR 136, as may
<br />be amended from time to time. All are sometimes re-
<br />ferred to herein as "grease" or "greases."
<br />C. "Fixture" means a plumbing fixture is a de-
<br />vice which is part of a system to deliver and drain away
<br />water, but which is also configured to enable a particular
<br />use. The most common plumbing fixtures are: water
<br />closets (known as toilets), urinals, bathtubs, showers,
<br />bidets, sinks (kitchen and utility), drinking fountains,
<br />and hose bibs (connections for water hoses). Water clos-
<br />ets, urinals, and bidets shall not be connected to sewer
<br />lines intended for grease interceptor or grease trap ser-
<br />vice.
<br />D. "Food service establishments" means those
<br />establishments engaged in preparing, serving, or other-
<br />wise making available food for consumption by the pub-
<br />lic. These establishments include but are not limited to
<br />restaurants, commercial kitchens, caterers, grocery
<br />stores and markets, hotels, schools, hospitals, prisons,
<br />corzec[ional facilities and senior care living facilities.
<br />These establishments use one or more of [he following
<br />preparation activities: cooking by frying, baking, grill-
<br />ing, rotisserie cooking, broiling, boiling, blanching,
<br />roasting, toasting, poaching, infrared heating, searing,

<br />tacle that requires washing.
<br />E. "Grease interceptor" means an interceptor of
<br />at least 750 gallons capacity to serve one or more fix-
<br />tures. A stmcture or device designed for the purpose of
<br />removing and preventing fats, oils and grease from en-
<br />tering the sanitary sewer collection system. These de-
<br />vices are often below-ground units in outside areas and
<br />are built as two or three chamber baffled tanks.
<br />F. "Grease trap" means a device designed to
<br />retain grease from one to a maximum of four fixtures. A
<br />device designed for the purpose of removing and pre-
<br />venting fats, oils and grease from entering the sanitary
<br />sewer collection system. Such [raps are typically under-
<br />the-sink units that are near food preparation areas with a
<br />minimum grease containment capacity of 40 pounds and
<br />flow rate of 20 gallons per minute (gpm).
<br />G. "Minimum design capability" means the
<br />design features of a grease interceptor and its ability or
<br />volume required to effectively intercept and retain
<br />greases from grease-laden wastewaters discharged [o the
<br />public sanitary sewer. At a minimum, [he design capa-
<br />bility shall be consistent with the Califomia Plumbing

<br />charge of wastewater into sewers within the city's

<br />wastewater from mobile sources, such as those who dis-
<br />charge hauled wastewater. (Ord. 1984 § I, 2008)
<br />15.44.030 Food service establishment permit
<br />requirement.
<br />All food service establishments are required to
<br />obtain a permit in order to discharge wastewater into the
<br />city's sanitary sewer collection system. It is unlawful for
<br />any person or food service establishment to discharge or
<br />cause to be discharged any fat, oil or grease into the
<br />sewer system without first obtaining a permit from the
<br />424- I (Pleasamon Supp. No. I, 1-09)
