For the purposes of this chapter, the following words and phrases shall have the meanings ascribed to them by this chapter. Words and phrases not ascribed a meaning by this chapter shall have the meanings ascribed by the Clean Water Act (33 USC 1251 et seq.), and Division 7 of the California Water Code, as they may be amended from time to time, if defined therein, and if not, by the definitions in any applicable permit issued by the California Water Resources Control Board or the California Regional Water Quality Control Board, Santa Ana, as appropriate, as such permits may be amended from time to time.

(5) Developments of 2,500 square feet or more of impervious surface adjacent to (within 200 feet) or discharging directly into environmentally sensitive areas.
(6) Parking lots of 5,000 square feet or more exposed to storm water. “Parking lot” is defined as a site or facility for the temporary storage of motor vehicles.
(7) Retail gasoline outlets that are 5,000 square feet or more with a projected average daily traffic of 100 or more vehicles per day.
(8) Emergency public safety projects in any of the above-listed categories may be excluded if the delay caused due to the requirement for a WQMP compromises the public safety, public health or environmental protection.
(9) New development does not include routine maintenance to maintain original line and grade, hydraulic capacity, or original purpose of a facility, nor does it include emergency new developments required to protect public health and safety.
(K) “Non-storm water” shall mean all discharges to and from a storm water conveyance system that do not originate from precipitation events (i.e., all discharges from a conveyance system other than storm water). Non-storm water includes illicit discharges, non-prohibited discharges, and NPDES permitted discharges.
(L) “Non-storm water discharge” shall mean any discharge to the storm drain system that is not entirely composed of storm water.
(M) “Person” shall mean an individual, association, partnership, corporation, municipality, state or federal agency, agent or employee thereof, firm, association, club, organization, business trust, company or any other entity that is by law deemed to be a separate entity subject to the obligations of this chapter.
(N) “Pollutant” shall mean any agent that may cause or contribute to the degradation of water quality such that a condition of pollution or contamination is created or aggravated. Pollutants may include, but are not limited to, paints, oil and other automotive fluids, soil, rubbish, trash, garbage, debris, refuse, waste, fecal conform, fecal streptococcus, enterococcus, heavy metals, hazardous waste, chemicals, fresh concrete, yard waste, animal waste, materials that result from the process of constructing a building or structure, noxious or offensive matter of any kind, sewage, wash water from restaurant floor mats and trash bins, gas stations, automobile service facilities, steam and pressure cleaning, carpet/upholstery cleaning, and pool cleaning; water from municipal, industrial, commercial sites, including parking lots, streets, sidewalks, driveways, patios, plazas, work yards, and outdoor eating or drinking areas; chlorine; biocides; grease; and food waste.
(O) “Premises” shall mean any building, lot, parcel of land, land or portion of land whether improved or unimproved.
(P) “Rainy Season” shall mean October 1 through May 31 of each year.
(Q) “Significant Redevelopment” shall mean the addition or replacement of 5,000 square feet or more of impervious surface on an existing developed site. This includes, but is not limited to, construction of additional buildings and/or structures, extension of the existing footprint of a building, construction of impervious or compacted soil parking lots. Significant redevelopment does not include routine maintenance activities that are conducted to maintain original line and grade, hydraulic capacity, the original purpose of the facility or emergency actions required to protect public health and safety.
(R) “Site Design BMPs” shall mean any project design feature that reduces the creation or severity of potential pollutant sources or reduces the alteration of the project site’s natural flow regime. Redevelopment projects that are undertaken to remove pollutant sources (such as existing surface parking lots and other impervious surfaces) or to reduce the need for new roads and other impervious surfaces (as compared to conventional or low-density new development) by incorporating higher densities and/or mixed land uses into the project design, are also considered site design BMPs.
(S) “Source Control BMPs” shall mean activities or programs to educate the public or provide low cost non-physical solutions, as well as facility design or practices aimed to limit the contact between pollutant sources and urban runoff or authorized non-storm water. Examples include activity schedules, prohibitions of practices, street sweeping, facility maintenance, detection and elimination of illicit connections and illegal dumping and other non-structural measures. Facility design examples include providing attached lids to trash containers, or roofs or awnings over material in trash storage areas to prevent direct contact between water and pollutants.
(T) “Storm Drain System” shall mean any facility within the incorporated areas of the city by which storm water may be conveyed to waters of the United States. Storm drain system includes, but is not limited to, any roads with drainage systems, streets, curbs, gutters, catch basins, natural and artificial channels, ditches, aqueducts, storm drains, inlets, conduit or other drainage structures.
(U) “Storm Water” shall mean runoff from urban, open space, and agricultural areas consisting only of those discharges that originate from precipitation events. Storm water is that portion of precipitation that flows across a surface to the storm drain system or receiving waters. Examples of this phenomenon include: the water that flows off a building’s roof when it rains (runoff from an impervious surface); the water that flows into streams when snow on the ground begins to melt (runoff from a semi-pervious surface); and the water that flows from a vegetative surface when rainfall is in excess of the rate at which it can infiltrate into the underlying soil (runoff from a pervious surface).
(V) “Structural BMPs” shall mean physical facilities or controls which may include secondary containment, treatment measures (e.g., first flush diversion, detention/retention basins, and oil/grease separators), runoff controls (e.g., grass swales, infiltration trenches, basins, etc.), and engineering and design modification of existing structures.
(W) “Treatment Control BMPs” shall mean an engineered system designed and constructed to remove pollutants from urban runoff. Pollutant removal is achieved by simple gravity, settling of particulate pollutants, filtration, biological uptake, media absorption or other physical, biological, or chemical processes.
(X) “Urban Runoff” shall mean those discharges from residential, commercial, industrial, and construction areas within the permit area, excluding discharges from feedlots, dairies, farms, and open space. Urban runoff discharges consist of storm water and non-storm water surface runoff from drainage sub-areas with various, often mixed, land uses within all of the hydrologic drainage areas that discharge into waters of the United States.
(Y) “Waters of the United States” shall mean navigable surface waters and all tributary surface waters to navigable surface waters, as further defined in 40 CFR 122.2. Groundwater is not considered to be waters of the United States. Waters of the United States do not include prior converted cropland. For purposes of the Clean Water Act, the final authority regarding the jurisdiction of the Clean Water Act remains with the United States Environmental Protection Agency (USEPA).
(Z) “WQMP” shall mean Water Quality Management Plan.
