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 rain water (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.

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.

The new land development requirements became effective on October 11, 2011. New Development and Redevelopment projects, which applications have not been deemed complete for processing before the effective date, will be subject to new rules if they meet Applicability Criteria defined by the Regional Water Quality Control Board.

For more information on Applicability Criteria, refer to County Stormwater Program's Policies section here.

For more information on the how the effective date applies to your project see pages 1-8 of the updated Manual available at http://www.vcstormwater.org/technicalguidancemanual.html.

If your project, located within the County Unincorporated area, is subject to new land development requirements for Post-Construction Stormwater Management Plan (PCSMP), refer to the following websites for additional information and forms:
