As used in this article:
"Best management practices (BMPs)"mean schedules of activities, prohibitions of practices, general good housekeeping practices, pollution prevention and educational practices, maintenance procedures, and other management practices to prevent the discharge of pollution directly or indirectly into stormwater, receiving waters, or stormwater conveyance systems. BMPs also include treatment practices, operating procedures, and practices to control site runoff, spillage or leaks, sludge or water disposal, or drainage from raw materials storage.
"Development"means any activity that moves soils or substantially alters the pre-existing vegetated or man-made cover of any land. Development includes any activity that may be considered new development or redevelopment. This also includes, but is not limited to, grading, digging, cutting, scraping, stockpiling or excavating of soil, placement of fill materials, paving, pavement removal, exterior construction, substantial removal of vegetation where soils are disturbed including, but not limited to, removal by clearing or grubbing, or any activity which bares soil or rock or involves streambed alterations or the diversion or piping of any watercourse. Development does not include routine maintenance to maintain original line and grade, hydraulic capacity, or the original purpose of the facility, nor does it include emergency construction activities (i.e., land disturbances) required to protect public heath and safety.
"Discharge"means the release, threatened release, or placement of any material into the county's storm drain system, including, but not limited to, stormwater, wastewater, solid materials, liquids, hazardous waste, raw materials, debris, litter, or any other substance.
"Enforcement agency."The Placer County department of public works is the primary enforcement agency for the purposes of this article. The enforcement agency shall coordinate program activities with and authorize personnel of other departments to serve as enforcement officials to effectuate the purposes of this article.
"Enforcement official"means any agent of the county authorized by the enforcement agency to enforce compliance with this chapter.
"Illicit connection."An illicit connection is defined by either of the following:
1. Any drain or water conveyance facility, either surface or subsurface, which allows an illicit discharge to enter the storm drain system, including, but not limited to, any conveyances which allow any nonstormwater discharge including sewage, process wastewater, and wash water to enter the storm drain system and any connection to the storm drain system from indoor drains and sinks, regardless of whether such drain or connection has been previously allowed, permitted, or approved by a government agency; or
2. Any drain or conveyance connected from a commercial or industrial land use to the storm drain system which has not been documented in plans, maps, or equivalent records and approved by the county.
"Illicit discharge"means any direct or indirect nonstormwater discharge to the county's municipal storm drain system, except as otherwise exempted, including the introduction of pollution into the storm drain system.
"Low impact development"means a sustainable practice that benefits water supply and contributes to water quality protection. Unlike traditional stormwater management, which collects and conveys stormwater runoff through storm drains, pipes, or other conveyances to a centralized stormwater facility, LID takes a different approach by using site design and stormwater management to maintain the site's pre-development runoff rates and volumes. The goal of LID is to approximate a site's pre-development hydrology by using design techniques that infiltrate, filter, store, evaporate, and detain stormwater runoff close to the source of rainfall.
"Maximum extent practicable (MEP)"means a technology-based standard established by Congress in the Clean Water Act Section 402(p)(3)(B)(iii) for stormwater discharge to apply to all small municipal separate storm sewer system (MS4) operators regulated under the NPDES program. MEP is generally the result of emphasizing pollution prevention and source control best management practices (BMPs) as the preferred method of preventing water pollution. The MEP approach is an ever-evolving, flexible and advancing concept, which considers technical and economic feasibility. As knowledge about controlling urban runoff continues to evolve, so does what constitutes MEP.
"Municipal separate storm sewer system (MS4)"means a conveyance or system of conveyances (including roads with drainage systems, municipal streets, catch basins, curbs, gutters, ditches, man-made channels, or storm drains) owned by a state, county, city, town, or other public body, that is designed or used for collecting or conveying stormwater, which is not a combined sewer, and which is not a part of a publicly owned treatment works.
"Nonstormwater discharge"means a discharge to the storm drain system that is not composed entirely of stormwater and that has been polluted, as defined in this section.
"Pollutant"means anything which causes or contributes to pollution, as defined in this section. Pollutants include, but are not limited to: paints, varnishes, solvents, oil, automotive fluids, yard wastes, refuse, rubbish, garbage, litter, discarded or abandoned objects, floatable materials, pesticides, herbicides, fertilizers, detergents, soaps, hazardous substances, hazardous waste, sewage, fecal coliform and pathogens, dissolved and particulate metals, animal wastes, wastes and residues that result from constructing a building or structure (including, but not limited to, sediments, slurries, and concrete rinsates), and noxious or offensive matter of any kind.
"Pollution"means the human-made or human-induced alteration of the quality of waters to a degree that causes or contributes to an exceedance of water quality standards contained in the statewide water quality control plan, the California Toxics Rule, or in the applicable regional water quality control board basin plan.
"Porter-Cologne Act"means the Porter-Cologne Water Quality Control Act, as amended (California Water Code Section
13000 et seq.).
"Property owner"means any person, entity, company, and/or authorized representative having title to real property within the geographic area affected by this article.
"Storm drain system,"also "municipal storm drain system," means facilities owned or operated by the county by which stormwater is collected and/or conveyed, including, but not limited to, any roads with drainage systems, municipal streets, gutters, curbs, inlets, piped storm drain, pumping facilities, retention and detention basins, natural and human-made or altered drainage channels, reservoirs, and other drainage structures which are within the county and are not part of a publicly owned treatment works as defined at 40 CFR Section
122.2.
"Stormwater"means any surface flow, runoff, and drainage consisting entirely of water from precipitation events, which has not been polluted.
"Urgency abatement."Urgency involves the discharge or a threatened discharge condition which causes or threatens to cause an imminent threat to public health, safety, welfare, the environment, or a violation of a NPDES permit.
"Waters of the state"means all surface watercourses and water bodies, including lakes, bays, ponds, impounding reservoirs, springs, wells, rivers, streams, creeks, marshes, inlets, canals, and all other bodies of surface waters (Porter Cologne Section 13050(e)), and which are within the county of Placer. This definition includes, but is broader than, waters of the United States.
"Waters of the United States"means surface watercourses and water bodies as defined at 40 CFR Section
122.2, including all natural waterways and definite channels and depressions in the earth that may carry water, even though such waterways may only carry water during rains and storms and may not carry stormwater at and during all times and seasons.
Any term(s) defined in the Federal Clean Water Act, as amended, and/or defined in the regulations for the stormwater discharge permitting program issued by the Environmental Protection Agency, as amended, and which are not specifically defined in this section, shall, when used in this article, have the same meaning as set forth in such act or regulation. |
