2011 Update to Ventura Countywide Technical Guidance Manual for Stormwater Quality Control Measures
The 2011 Update to the Ventura County Technical Guidance Manual for Stormwater Quality Control Measures was approved by the Executive Officer of the Regional Water Quality Control Board in July 2011.

Illicit Discharge Reporting Hotline
Question: What is an Illicit Discharge?
Answer: An illicit discharge is any activity or event which results in a release, leak, flow, escape or the placement of any material other than rainwater (including liquids or solids) into the storm drain system. Certain exemptions exist for emergency firefighting activities, irrigation runoff, individual residential car washing, or discharges covered by a separate National Pollutant Discharge Elimination System (NPDES) permit.
- To report an illicit discharge to the storm drain within areas of unincorporated Ventura County, please email, call (805) 650-4064, or submit a report online (by going to the “Watershed Protection” tab and then “Illicit Discharges or Connections”).
- To report sewage, wastewater or hazardous material discharges, please contact the Ventura County Environmental Health Division at (805) 654-2813. For after hours on-call emergency response, please call (805) 320-6244.
