Storm Water

In 1999, the State Water Resources Control Board (SWRCB) issued a National Pollutant Discharge Elimination System (NPDES) permit that regulates storm water discharges from Caltrans facilities. The permit requires Caltrans to maintain and implement an effective Storm Water Management Plan (SWMP) that identifies and describes the Best Management Practices (BMPs) used to control the discharge of pollutants to waters of the United States.

This Guide describes the process for Caltrans staff to incorporate the BMPs from the SWMP into the planning and design phases of a project. It is important to note that this guide provides only minimum guidelines, and that storm water controls other than what are included may need to be incorporated on a project-by-project basis to comply with special requirements from a Regional Water Quality Control Board. This Guide may be updated as needed to reflect changes to the SWMP.
