Storm Water

Fred-Izzy-videos-thumbMotor oil, paint products, chemicals, litter and other pollutants contaminate local waterways and threaten wildlife when they enter storm drains. Releasing pollutants that threaten the watershed may result in significant penalties and cleanup costs.

Environmental Services responds to reports of illegal dumping into storm drains by individuals and businesses and enforces federal, state and local water quality laws and regulations by inspecting local  facilities to ensure that they comply with water quality regulations.

To report a spill or illegal dumping to the storm drain system:

  • 510-577-3401 - or – 510-577-3434 during business hours (Mon - Fri,  7:30am - 5:00pm).
  • After-hours/Weekends:  510-577-3459 (5:00pm - 7:30am) - or - 510-577-2740 SLPD non-emergency dispatch.

Senate Bill 205 - Business Licenses: Storm Water Discharge Compliance

Senate Bill 205 (2019) became effective January 1, 2020. This Senate Bill requires a person applying to a city or county for a new or renewed business license to demonstrate enrollment in a National Pollutant Discharge Elimination System (NPDES) storm water permit, if required. Prior to the issuance or renewal of a business license, the City determines whether any of the primary Standard Industrial Classification (SIC) codes provided by the business are potentially regulated by the NPDES General Permit for Storm Water Discharges Associated with Industrial Activities (Industrial General Permit).

A list of SIC codes potentially regulated by the Industrial General Permit is posted on the State Water Resources Control Board’s website, sorted numerically and alphabetically
