BEST MANAGEMENT PRACTICES OR BMPs: Activities, prohibitions, maintenance procedures and other management practices to prevent or reduce the introduction of FOG into the public sewer system.
BLOCKAGE: A partial or complete obstruction of wastewater flowing through a sewer pipeline.
CHANGE IN LAW: A change to any state or federal law, permit or regulation; changes to this code; changes to any city national pollutant discharge elimination system (NPDES) permit or waste discharge requirement (WDR); or the subsequent existence of any court order, consent decree, injunction or other regulatory or legal imposition that affects the use and/or operation of the city's sanitary sewer system and any other public or private sanitary sewer systems, lines or other public or private infrastructure that connects to the city's sanitary sewer system.
CHANGE IN OPERATIONS: Any change in the ownership, food types, or operational procedures that have the potential to change the amount of fats, oils and grease (FOG) discharged by a food service establishment (FSE) to the city's wastewater collection and treatment system.
CITY: The city of Placerville, a municipal corporation of the state of California.
COLLECTION SYSTEM: The public sewer system consisting of all pipes and conveyance system components conveying wastewater to the city's wastewater treatment plant (Hangtown Creek Water Reclamation Facility (HCWRF)).
COMMISSARY: An establishment which is used as a base of operations for one or more motorized food wagons or pushcarts, where such unit or units and/or equipment are serviced, cleaned, supplied and/or maintained.
COMPOSITE SAMPLE: A collection of individual samples obtained at selected intervals based on an increment of either flow or time. The resulting mixture (composite sample) is intended to form a representative sample of the waste stream discharged during the sample period.
DESIGN HYDRAULIC DEPTH: Total operating depth of interceptor contents at which interceptor is designed to operate.
DIRECTOR: The city of Placerville director of public works or authorized representative.
ENFORCEMENT OFFICER: Any city employee or agent of the city with authority to enforce the provisions of this chapter and the authority to make any decision, on behalf of the director, required or called for by this chapter.
FATS, OILS AND GREASE OR FOG: Any substance such as vegetable or animal product that is used in, or is a byproduct of, the cooking or food preparation process, and that becomes or may become viscous, or solidifies or may solidify, with a change in temperature or other conditions.
FOOD GRINDER: Any device installed in the plumbing or wastewater system for the purpose of grinding food or food waste.
FOOD SERVICE ESTABLISHMENT OR FSE: A facility, including, but not limited to, any commercial or institutional entity within the sanitary sewer service area of the regional wastewater control facility, operating in a permanent structure such as a room, building or place, or portion thereof, maintained, used or operated for the purpose of storing, preparing, serving, manufacturing, packing or otherwise handling food for sale to other entities, or for consumption by the public, its members or employees, and which has any process or device that uses or produces FOG, or grease vapors, steam, fumes, smoke or odors that are required to be removed by an exhaust hood pursuant to California Health And Safety Code section 114149.1 or in accordance with the California uniform retail food facilities law (CURFFL) 1 . The term "food service establishment" or "FSE" also means any commissary where food is prepared using fats, oils or grease and/or which receives water from motorized food wagons or pushcarts containing fats, oils or grease. A limited food preparation establishment is not considered an FSE when engaged only in reheating, hot holding, or assembly of ready to eat food products, provided that the establishment has no wastewater discharge containing a significant amount of FOG.
GRAB SAMPLE: A sample taken from a waste stream on a onetime basis without regard to the flow in the waste stream and without consideration of time.
GREASE CONTROL DEVICE: Any grease interceptor, grease trap or other mechanism, device or process which attaches to, or is applied to, wastewater plumbing fixtures and lines, the purpose of which is to trap, collect or treat FOG prior to it being discharged into the public sewer.
GREASE INTERCEPTOR: A multicompartment device that primarily uses gravity to separate FOG from the wastewater as it moves from one compartment to the next. The design, construction, sizing and installation of grease interceptors shall conform to this chapter and the most current edition of the California plumbing code. In the event of conflict, this chapter will control.
GREASE TRAP: A grease control device that is used to serve individual plumbing fixtures. A grease trap is typically installed indoors, under or near a dishwashing sink.
HOT SPOTS: Sewer lines that have experienced grease related blockages or sanitary sewer overflows (SSOs) and that must be cleaned or maintained frequently to avoid blockages of the public sewer.
INSPECTOR: A person authorized by the director to inspect any existing or proposed wastewater generation, conveyance, processing and/or disposal facilities.
INSTITUTION: A school, church, hospital, convalescent home or other similar entity.
INTERCEPTOR: See definition of Grease Interceptor.
LATERAL: The private sewer line connecting a home or other structure to the city's sewer main, including the portion of the line lying within the public right of way, often referred to as the "lower" lateral.
MANIFEST: That receipt which is retained by an FSE for the disposal of FOG, recyclable wastes and/or liquid wastes.
NEW CONSTRUCTION: Any structure planned or under construction for which a sewer connection permit has not been issued.
PERSON: Any individual, partnership, copartnership, firm, company, association, society, corporation, joint stock company, trust, estate, governmental entity or any other legal entity, or their legal representatives, agents or assigns. The masculine gender shall include the feminine and the singular shall include the plural where indicated by context.
PUBLIC SEWER: A sewer system which is controlled by a public authority.
REMODEL OR REMODELING: Any physical and/or operational change to an FSE that involves any one or a combination of the following:
(A) Under slab plumbing in the food processing area;
(B) A thirty percent (30%) or greater increase in the net public seating area;
(C) A thirty percent (30%) or greater increase in the size of the kitchen area;
(D) Any change in the size or type of food preparation equipment;
(E) Any remodel, addition, alteration or repair valued greater than seventy five thousand dollars ($75,000.00).
RESPONSIBLE PERSON: A person who the director determines is responsible for causing, permitting, or maintaining a public nuisance or a violation of this code, any applicable uniform code, applicable state codes, any national pollutant discharge elimination system (NPDES) permit or any wastewater discharge permit.

STORM DRAIN: A pipe or conduit for carrying storm and surface waters and drainage, but excludes wastewater and industrial wastes, other than unpolluted cooling water.
TWENTY FIVE PERCENT RULE: Requirement for grease interceptors to be maintained such that the combined FOG and solids accumulation does not exceed twenty five percent (25%) of the design hydraulic depth of the grease interceptor. This is to ensure that the minimum hydraulic retention time and required available hydraulic volume are maintained to effectively intercept and retain FOG discharged to the sewer system.
WASTE: Wastewater and any and all other waste substances, liquid, solid, gaseous or radioactive, associated with human habitation or of human or animal nature, including such wastes placed within containers of whatever nature prior to and for the purpose of disposal.
