For the purposes of this chapter, unless otherwise apparent from the context, words and phrases set forth in this section shall have the following meanings:
"Authorized enforcement official" means the public works director or designee.
"BASMAA Post Construction Manual" means the most recent version of the Bay Area Stormwater Management Agencies (BASMAA) Post Construction Manual.
"Best management practices (BMPs)" means schedules of activities, prohibitions of practices, general good housekeeping practices, pollution prevention practices, maintenance procedures and other management practices to prevent or reduce the discharge of pollutants directly or indirectly into the waters of the United States. BMPs also include treatment requirements, operating procedures and practices to control plant site runoff, spillage or leaks, sludge or waste recycling or disposal, or drainage from raw material storage.
"City" means the city of American Canyon, a municipal corporation, situated in Napa County, California.
"Construction activity" means any activity that involves soil disturbing activities including, but not limited to, clearing, paving, grading, disturbances to ground such as stockpiling, and excavation.
"Development runoff requirements" mean the provisions in the Phase II Stormwater Permit that contain design standards or performance criteria to address both construction and post-construction phase impacts of new and redeveloped projects on stormwater quality and quantity.
"Discharge of a pollutant" means: (a) the addition of any pollutant or combination of pollutants to receiving waters from any point source; or (b) addition of any pollutant or combination of pollutants to the waters of the contiguous zone or the ocean from any point source other than a vessel or other floating craft which is being used as a means of transportation. The term includes additions of pollutants to receiving waters from: surface runoff which is collected or channeled by man; discharges through pipes, sewers, or other conveyances owned by a state, municipality, or other person which do not lead to a treatment works; and discharges through pipes, sewers, or other conveyances, leading into privately owned treatment works.
"Erosion and Sediment Control Plan" means a plan prepared to control erosion and sediment discharges from a construction site that meets those criteria identified in the most recent version of the Napa Countywide Erosion and Sediment Control Plan Model Template and any issued Technical Bulletins.
"Illicit connection" means any device or method that conveys non-stormwater discharge to a storm drain or receiving water.
"Illicit discharge" means any discharge to storm drain or receiving water that is prohibited under local, state, or federal statutes, ordinances, codes, or regulations. The term illicit discharge does not include discharges that are regulated by an NPDES permit (other than the Phase II Stormwater Permit) and discharges that are identified under the exceptions to discharge prohibition section of this chapter.
"Incidental irrigation runoff" means unintended amounts (volume) of runoff, such as unintended, minimal over-spray from sprinklers that escapes the landscaped area of intended use. Water leaving an intended use area is not considered incidental if it is part of the facility design, if it is due to excessive application, if it is due to intentional overflow or application, or if it is due to negligence.
"Low impact development (LID)" means a sustainable practice that benefits water supply and contributes to water quality protection. LID uses site design and stormwater management to maintain the site's pre-development runoff rates and volumes. The goal of LID is to mimic a site's predevelopment hydrology by using design techniques that infiltrate, filter, store, evaporate, and detain runoff close to the source of rainfall.
"National Pollutant Discharge Elimination System (NPDES) Permit" means a permit issued by the U.S. Environmental Protection Agency, State Water Resources Control Board, or the California Regional Water Quality Control Board pursuant to the Clean Water Act, 33 U.S.C. Section 1251 et seq., (CWA) that authorizes discharges to waters of the United States and requires the reduction of pollutants in the discharge.
"NCSPPP" is the Napa Countywide Stormwater Pollution Prevention Program.
"Non-stormwater discharge" means any discharge to a storm drain or receiving water that is not entirely composed of stormwater.
"Phase II Stormwater Permit" means the NPDES general stormwater permit applicable to the City of American Canyon, Water Quality Order No. 2013-0001—DWQ, General Permit No. CAS000004, and any subsequent amendment, reissuance or successor to this permit.
"Pollutant" means dredged soil, solid waste, incinerator residue, filter backwash, sewage, pet wastes, manure, garbage, sewage sludge, munitions, chemical wastes, biological materials, radioactive materials, wrecked or discarded equipment, sediment, rock, sand, cellar dirt, and industrial, municipal and agricultural waste discharged into a storm drain or receiving water.
"Post-Construction Measures Requirements" means the provisions in Section E.12 of the Phase II Stormwater Permit that contain design standards or performance criteria to address the post-construction phase impacts of new projects and redeveloped projects on stormwater quality and quantity.
"Premises" means any building, lot parcel, real estate, or land or portion of land whether improved or unimproved, including adjacent sidewalks and parking strips.
"Receiving waters" means all waters that are "waters of the United States" within the scope of the Federal Clean Water Act or "waters of the state" within the scope of the California Water Code, including, but not limited to, natural streams, creeks, rivers, reservoirs, lakes, ponds, water in vernal pools, lagoons, estuaries, bays, the Pacific Ocean, and groundwater.
"Storm drains" includes, but is not limited to, those stormwater drainage conveyance facilities within the city, both public and private, by which stormwater may be conveyed to the receiving waters, including any roads with drainage systems, municipal streets, catch basins, curbs, gutters, ditches, manmade channels or storm drains, which are not part of a publicly owned treated works (POTW) as defined at 40 Code of Federal Regulations (C.F.R.) 122.2, or successor regulation.
"Stormwater" means stormwater runoff, snow melt runoff, and surface runoff and drainage.
"Stormwater Control Plan (SCP)" means a plan that meets those criteria contained in the most recent version of the BASMAA Post Construction Manual and any issued Technical Bulletins.
"Stormwater Facilities Operation and Maintenance Plan" means a plan identifying the locations and characteristics of stormwater management facilities on a newly developed or redeveloped site and describing maintenance activities, schedules, and responsibilities to ensure the ongoing proper operation of those facilities.
"Stormwater management facility" means any device designated to detain, retain, filter, or infiltrate stormwater.
"Stormwater Pollution Prevention Plan (SWPPP)" means a document which describes the best management practices to be implemented by the owner or operator of a business or construction site to eliminate illicit discharges and/or reduce pollutant discharges to the stormwater conveyance system.
"Technical Bulletin" means a document issued by and under the authority of the director of public works to revise, amend, augment guidance manuals, documents, and templates including but not limited to the BASMAA Post Construction Manual and the Napa Countywide Erosion and Sediment Control Plan Model Template.
"Urban runoff" means stormwater from an urbanized area including streets and adjacent domestic and commercial properties that carries pollutants of various types into the storm drainage system and receiving waters.
"Watercourse" means a stream of water usually flowing in a definite channel having a bed and sides, or banks, and discharging itself into some other stream or body of water. It is unnecessary for a watercourse be exclusively the work of nature.
All other terms used in this chapter shall have the same meaning as defined in the Federal Clean Water Act (33 U.S.C. Section 1251 et seq.), as amended, the regulations for the stormwater discharge program issued by the Environmental Protection Agency on November 16, 1991, as amended, and the Phase II Stormwater Permit.
