Storm Water Programs and Permits

Stormwater runoff contains many types of pollutants from the urban and industrial landscape. Stormwater runoff or urban runoff does not receive treatment in most cases, and is the single largest source of surface water pollution to Bay Area waters. The Water Board regulates stormwater quality under authorities of the federal Clean Water Act and California’s Porter-Cologne Water Quality Control Act. We issue NPDES permits to dischargers of municipal and industrial stormwater runoff and operators of large construction sites.
