Tentative Regional MS4 Permit 
The Los Angeles Regional Water Quality Control Board released the tentative Regional Phase I Municipal Separate Storm Sewer System (MS4) National Pollutant Discharge Elimination System (NPDES) Permit (Tentative Regional MS4 Permit) for public comment on August 24th. Comments were due to the Regional Board on December 7, 2020. If adopted, the Tentative Regional MS4 Permit would apply to Ventura and Los Angeles Counties and all incorporated cities therein, and would supersede the three Orders that currently cover the area, R4-2010-0108 (Ventura County), R4-2012-0175 (L.A. County except for the City of Long Beach), and R4-2014-0024 (City of Long Beach), except for purposes of enforcement. Please check the Regional Board's website for updates on future Permit renewal workshops, response to comments, and other important information related to the proposed Regional Permit.
Wildfires in Ventura County
Wildfires have many impacts on both the community and our resources, including hazards from ash and toxins, and an increased risk of flooding and landslides. Here are some answers to FAQs about post-fire water quality concerns and erosion and sediment control. The County of Ventura launched a website dedicated to helping victims of Ventura County wildfires find information to help their recovery, including debris removal, rebuilding, permits, hazardous materials, health issues, how to get rain ready, and much more. Please visit www.VenturaCountyRecovers.org for more information.
