About Storm Water
Storm water is defined by US EPA as the runoff generated when precipitation from rain and snowmelt events flows over land or impervious surfaces without percolating into the ground. Storm water is often considered a nuisance because it mobilizes pollutants such as motor oil and trash. In most cases, storm water flows directly to water bodies through sewer systems, contributing a major source of pollution to rivers, lakes, and the ocean. Storm water discharges in California are regulated through National Pollutant Discharge Elimination System (NPDES) permits. However, storm water may also act as a resource and recharge to groundwater when properly managed. The Water Boards are actively involved in initiatives to improve the management of storm water as a resource.

Storm Water Permitting
The Water Boards draw authority for storm water regulation from the federal Water Pollution Control Act (Clean Water Act) and from direction within the Clean Water Act which puts the framework for regulating storm water discharges under the National Pollutant Discharge Elimination System (NPDES) Permit system. Data collected for NPDES storm water permit compliance is available in the Storm Water Multiple Application and Report Tracking System (SMARTS) and the California Integrated Water Quality System (CIWQS). For more information read our Storm Water Management Fact Sheet.Permitting Program Pages
