"Best management practices (BMPs)"means schedules of activities, prohibitions of practices, general good housekeeping practices, pollution prevention and educational practices, maintenance procedures, and other management practices to prevent or reduce the discharge of pollutants directly or indirectly to storm water, receiving waters, or MS4. 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.
"CASQA"means the California Stormwater Quality Association.
"Clean Water Act"means the Federal Water Pollution Control Act of 1972, codified at Chapter 26 of Title
33 of the United States Code.

"Construction General Permit"means the General Permit for Storm Water Discharges Associated with Construction and Land Disturbance Activities issued by the State Board, NPDES No. CAS000002, as it currently exists or may be amended and reissued from time to time. The Construction General Permit covers, in part, construction activity that results in a land disturbance of equal to or greater than one acre. The Construction General Permit is available from the State Board and may be reviewed on the internet at:

"Construction site"means the premises where any project that involves any construction activity is located, including projects requiring coverage under the Construction General Project.
"Development"means any land disturbing activity that falls under the city's planning or permitting authority, including any construction activity, construction or installation of a building or structure, creation of impervious surfaces; or land subdivision. Development does not include trenching, excavation and resurfacing associated with linear underground/overhead projects; pavement grinding and resurfacing of existing roadways; construction of new sidewalks, pedestrian ramps, or bike lanes on existing roadways; or routine replacement of damaged pavement such as pothole repair or replacement of short, noncontiguous sections of roadway.

"Illicit connection"means a pipe, drain, open channel, or other conveyance facility, or device, whether on the surface or subsurface, which allows an illicit discharge to enter the MS4 regardless of whether said drain or connection had been previously allowed, permitted, or approved by a government agency.

8.36.060 of this chapter.
"Illicit discharge"means any discharge that is either: (1) non-storm water discharge that violates an NPDES permit; or (2) any discharge that causes or contributes or threatens to cause or contribute to a violation of any plan standard. Illicit discharges are further specified in Section
8.36.050 of this chapter.
"Incidental runoff"means an unintended, unanticipated, and infrequent amount (volume) of water discharge from landscape irrigation, such as unintended, minimal over-spray from sprinklers that escapes the 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, or if it is due to intentional or grossly negligent overflow or application.
"Linear underground/overhead projects"include, but are not limited to, any conveyance, pipe, or pipeline for the transportation of any gaseous, liquid (including water and wastewater for domestic municipal services), liquiescent, or slurry substance; any cable line or wire for the transmission of electrical energy; any cable line or wire for communications (e.g., telephone, telegraph, radio, or television messages); and associated ancillary facilities.
"MS4" or "municipal separate storm sewer system"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, that discharges into waters of the United States and which is owned or operated by the city and designed or used for collecting or conveying storm water.
"National Pollutant Discharge Elimination System permit" or "NPDES permit"means a permit issued by the U.S. EPA, State Water Resources Control Board, or the California Regional Water Quality Control Board pursuant to the Clean Water Act that authorizes discharges to waters of the United States and requires the reduction of pollutants in the discharge. The city's NPDES permit is the State Board's Water Quality Order No. 2013-0001-DWQ, NPDES General Permit No. CAS000004, as it currently exists or may be amended and reissued from time to time.
"Plan standard"means any and/or all applicable requirements of the Water Quality Control Plan for Basin 2, adopted by the Regional Water Quality Control Board, San Francisco Bay Region in 1995, and all subsequent amendments.
"Pollutant"means any "pollutant" defined in Section 502(6) of the Clean Water Act or incorporated into the California Water Code Section
13373. Pollutants may include, but are not limited to, the following:
1. Residential, commercial and industrial waste (such as trash, litter, fuels, solvents, detergents, plastic pellets, hazardous substances, fertilizers, pesticides, slag, ash, and sludge);
