§ 11A-8. Reduction of pollutants in stormwater.

(a)

Activities Resulting in Discharge of Pollutants. Any person engaging in activities that may result in pollutants entering the county's stormwater system shall undertake all practicable measures to reduce and/or eliminate such pollutants. All activities that do actually, or may potentially, result in the deposit of pollutants in or on the county's stormwater system, in any tributary of this system, and all land which drains to either this system or any of its tributaries, shall be construed as activities that may result in pollutants entering the county's stormwater system. Examples of such activities include, but are not limited to, ownership and use of premises that may be a source of pollutants such as parking lots, gasoline stations, industrial facilities, business enterprises and dwelling units.

(b)

Pollutants and Littering. No person shall throw, deposit, leave, keep or permit to be thrown, deposited, placed, left or maintained, any refuse, household hazardous wastes or other hazardous waste, garbage, debris, or other wastes, or other discarded or abandoned objects or articles in or upon any stormwater system or upon any public or private plot of land in the applicable area so that the same might become a pollutant, except in lawfully established waste disposal facilities.

(c)

Sidewalks. The occupant or tenant or, in the absence of occupant or tenant, the owner or proprietor of any real property in the county in front of which there is a paved sidewalk shall maintain that portion of the sidewalk in front of the property free of dirt or litter to the maximum extent practicable. Sweepings from the sidewalk shall not be swept or otherwise made or allowed to go into the gutter or roadway or any element of any drainage system, but shall be disposed of in receptacles maintained as required for the disposal of solid waste.

(d)

Construction Activities. Any construction contractor performing work in the applicable area shall implement appropriate best management practices to prevent the discharge of construction wastes or debris or contaminants from the construction materials, tools, and equipment from entering the stormwater system.

(e)

Bodies of Water. No person shall throw or deposit litter in any fountain, pool, lake, stream, river or any other body of water within the applicable area.

(f)

Standard for Parking Lots, Paved Areas, and Related Stormwater Systems. Persons owning, operating, or maintaining a paved parking lot, the paved areas of a gas station, a paved private street, road, or driveway and related stormwater systems shall clean those structures as frequently and thoroughly as practicable in a manner that does not result in discharge of pollutants to the stormwater system.

(g)

Notification of Intent and Compliance with General Permits. Each industrial discharger, discharger associated with construction activity or other discharger described in any general stormwater permit addressing such discharges as may be adopted by the United States Environmental Protection Agency, the State Water Resources Control Board, or the California Regional Water Quality Control Board, North Coast Region, shall provide the notice of intent, comply with, and undertake all other activities required by any general stormwater permit applicable to such dischargers, and shall provide a copy of the notice of intent and of each annual report pursuant to any general stormwater permit to the administrative authority, and shall pay any associated monitoring and enforcement fees to the county that may be set by the board of supervisors. Each discharger identified in an individual NPDES permit relating to stormwater discharges shall comply with and undertake all activities required by such permit.

(h)

Compliance with Best Management Practices. Where best management practice guidelines or requirements have been adopted or published by the Environmental Protection Agency, any state of California agency, any San Francisco Bay area agency, or the county, for any activity, operation or facility that may cause or contribute to prohibited discharges, every person undertaking such activity or operation or owning or operating such commercial facility shall comply with such guideline or requirement.

(i)

Stormwater Pollution Prevention Plan. The administrative authority may require any business in the applicable area that engages in activities that may result in prohibited discharges to develop and implement a stormwater pollution prevention plan, which must include an employee training program. Business activities that may require a stormwater pollution prevention plan include, but are not limited to, maintenance, storage, manufacturing, assembly, equipment operations, vehicle loading or fueling, or cleanup procedures that are carried out partially or wholly out of doors.

(j)

Coordination with Hazardous Materials Release Response Plans and Inventory. Any business subject to the Hazardous Materials Release Response and Inventory Plan, Division 20, Chapter 6.95 of the California Health and Safety Code (commencing with Section 25500), shall include in that plan provision(s) for compliance with this chapter, including the prohibitions on non-stormwater discharges and the requirement to reduce the release of pollutants to the maximum extent practicable.
