Santa Margarita Watershed Water Quality Improvement Plan (WQIP)
The San Diego Regional Water Quality Control Board (RWQCB) adopted Order R9-2013-0001, a National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer Systems Permit (MS4 Permit or Permit) on May 8, 2013. This Order, which was amended in November of 2015 to include the Santa Margarita Region of Riverside County, requires local government in each of the region’s Watershed Management Areas (WMA) to develop Water Quality Improvement Plans (WQIPs). A WQIP for the Santa Margarita WMA is now being developed and it is scheduled to be completed by January 2018.

The goal of the Santa Margarita WMA WQIP is to further the Clean Water Act’s objective to protect, preserve, enhance, and restore the water quality and designated beneficial uses of waters of the state. This goal will be accomplished through a planning and management process that identifies the highest priority water quality conditions within the WMA, and implements strategies to achieve improvements in the quality of discharges from responsible agencies’ stormdrain systems.

MEMBER AGENCIES: Riverside County Flood Control and Water Conservation District is the Principal Permittee of the Santa Margarita MS4 Permit. The following Municipalities are Co-permittees:

  City of Temecula City of Wildomar County of San Diego
