Ventura County Air Pollution Control District
Draft 2004 Ventura County Ozone State Implementation Plan

On March 4, 2004, the Ventura County Air Pollution Control District (Ventura County APCD) released for public comment its draft 2004 Ozone SIP.  The Draft 2004 SIP contains on-road motor vehicle emissions budgets for ozone.  Upon local district adoption, ARB submittal to U.S. EPA, and a budget adequacy finding by U.S. EPA, these budgets must be used in transportation conformity determinations.

The draft motor vehicle emissions budgets listed and documented below represent the draft Ventura County 2004 Ozone SIP budgets, along with supporting materials under consideration by the Ventura County APCD.
