Stormwater and Illicit Discharge Investigations Program


Contra Costa Health Services - Hazardous Materials Programs (CCHSHMP) works cooperatively with Contra Costa County Department of Public Works, Watershed Program (CWP) to conduct stormwater inspections at industrial and commercial businesses and investigate illicit discharges to the County's storm drain system. The inspections and investigations are a part of the compliance requirements under the Federal Clean Water Act's National Pollutant Discharge Elimination System (NPDES) Program. In Contra Costa County, the San Francisco Bay (Region 2) and Central Valley (Region 5) Regional Water Quality Control Boards have each issued NPDES permits to Contra Costa County to control the discharge of pollutants to receiving waters from municipal stormwater. The CWP is responsible for ensuring Contra Costa County is in compliance with both NPDES permits.

Each year, the CWP is required to report inspection and investigation findings to the appropriate Regional Water Quality Control Board. Based on the requirements in the NPDES permits and previous year's inspection results, the CWP determines a list of facilities for CCHSHMP to inspect.

See more information regarding the CWP and its NPDES permits.
