§ 1014-4.012. Reduction of pollutants in stormwater.

(a)

Generally. Any person engaging in activities that may result in pollutants entering the county's stormwater system shall undertake all practicable measures to reduce such pollutants. Examples of such activities include the 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)

Litter. No person shall throw, deposit, leave, keep or permit to be thrown, deposited, placed, left or maintained, any refuse, rubbish, garbage or other discarded or abandoned objects, articles or other litter in or upon any street, alley, sidewalk, business place, creek, stormwater system, fountain, pool, lake, stream, river or any other body of water, or upon any public or private parcel of land, except in containers or 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 front of which there is a paved sidewalk, shall maintain the sidewalk 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, but shall be disposed of in receptacles maintained as required for the disposal of solid waste.

(d)

Parking Lots, Paved Areas and Related Stormwater Systems. Persons owning, operating or maintaining a paved parking lot, a paved area of a gasoline station, a paved private street or road, or a related stormwater system shall clean those premises as frequently and thoroughly as practicable in a manner that does not result in the discharge of pollutants to the county's stormwater system.

(e)

Best Management Practices for New Developments and Redevelopments. All construction contractors performing work in the unincorporated area of the county shall conform to the requirements of the California Stormwater Quality Association (CASQA) Stormwater Best Management Practice Handbooks for Construction Activities and New Development and Redevelopment, the Association of Bay Area Governments (ABAG) Manual of Standards for Erosion and Sediment Control Measures, the county's grading ordinance (Division 716 of the ordinance code), the ordinance codified in this chapter, and other generally accepted engineering practices for erosion control as required by the director. The director may establish controls on the volume and rate of stormwater runoff from new developments and redevelopment as may be appropriate to minimize the discharge and transport of pollutants.

(f)

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 regional water quality control board (San Francisco Bay Region or Central Valley Region), shall provide the notice of intent, comply with, and undertake all other activities required by any general stormwater permit applicable to such dischargers. Each discharger identified in an individual NPDES permit relating to stormwater discharges shall comply with and undertake all activities required by the permit.

(g)

Compliance with Best Management Practices. Where best management practices, guidelines or requirements have been adopted by any federal, state, regional, city or county agency, for any activity or operation of premises that may cause or contribute to stormwater discharges prohibited pursuant to Section 1014-4.006, every person who undertakes such activity, or operation, or who owns or operates such premises, shall comply with such guidelines or requirements.

(h)

Stormwater Pollution Prevention Plan. The director may require any business or utility in unincorporated areas of the county that is engaged in activities that may result in runoff pollutants or discharges prohibited by Section 1014-4.006 to develop and implement a stormwater pollution prevention plan, which must include an employee training program. Business activities which may require a stormwater pollution prevention plan include maintenance, storage, manufacturing, assembly, equipment operations, vehicle loading, fueling, vehicle maintenance, food handling or processing, or cleanup procedures that are carried out partially or wholly out of doors.

(i)

Coordination with Hazardous Material Release Response and Inventory Plans. Any business required by Chapter 6.95 of Division 20 of the Health and Safety Code (commencing with Section 25500) to submit a business plan or a risk management and prevention program (RMPP), or both, or any owner or operator of a hazardous water facility required by Chapter 15 of Division 4.5 of Title 22 of the California Code of Regulations to maintain a contingency plan, shall include in that plan or program provision for compliance with this division, including discharges prohibited under Section 1014-4.006 and the requirement to reduce the release of pollutants to the maximum extent practicable.

(j)

Coordination with Vector Control Plan. All design, construction, operation and maintenance of stormwater management facilities shall conform to the requirements of the Contra Costa Clean Water Program's Vector Control Plan, as approved by a regional water quality control board.
