Storm Water Program

Joint Effort: Implementing LID & Hydromodification Controls
MS4 Enrollment Strategy

The purpose of the Storm Water Program is to prevent stormwater runoff from acting as the vehicle for the discharge of pollutants to surface water bodies.

The Storm Water Program is a National Pollutant Discharge Elimination System (NPDES) Program implemented in two phases. The November 16, 1990 Federal Register describes the requirements of the Phase I Regulations and the December 8, 1999 Federal Register describes the Phase II regulations. The State of California carries out the Storm Water Regulations according to the California Water Code.

The Storm Water Program carries out it's purpose by permitting three categories of potential pollution sources:

Phase I (1990 - March 9, 2003)

For Region 3, Phase I includes three general permits and one individual permit. Construction Activities, Industrial activities and Caltrans activities are covered under separate general permits. The City of Salinas holds the only individual municipal storm water permit in the Central Coast Region.

The Phase II Final Rule was published in the Federal Register on December 8, 1999. The SWRCB adopted general permits for Phase II Regulated Small MS4s and Small Construction Activity. On March 10, 2003, Operators of Phase II Regulated Small MS4s and Small Construction Activity were required to obtain permit coverage.
