San Diego Region - Riverside County Storm Water Permit

Introduction

On July 14, 2004, the San Diego Regional Water Quality Control Board (Regional Board) adopted the Municipal Storm Water Permit for the portion of Riverside County within the San Diego Region, Order No. R9-2004-001 (NPDES Permit No. CAS0108766), Waste Discharge Requirements for Discharges of Urban Runoff from the Municipal Separate Storm Sewer Systems (MS4s) Draining the County of Riverside, the City of Murrieta, the City of Temecula and the Riverside County Flood Control and Water Conservation District within the San Diego Region. The transmittal letter posted below explains the changes that were made to the final Order based on Regional Board deliberations at the July 14, 2004 meeting.

Order No. 2004-001 regulates the manner in which the Permittees manage urban runoff in the Santa Margarita watershed. Urban runoff is one of the leading causes of water quality impairment in southern California today; for this reason Order No. 2004-001 includes extensive requirements to protect receiving waters from urban runoff discharges from MS4s. The Order and the Monitoring and Reporting Program, and other related documents are posted below. The Fact Sheet/Technical Report will be updated to reflect the final Order at a later date.
