Approval of California Air Plan Revisions, Ventura County Air Pollution Control District; Prevention of Significant Deterioration

The Environmental Protection Agency (EPA) is proposing to approve revisions to the Ventura County Air Pollution Control District (VCAPCD or District) portion of the California State Implementation Plan (SIP). The State of California (State) is required under the Clean Air Act (CAA or Act) to adopt and implement a SIP-approved Prevention of Significant Deterioration (PSD) permit program. These proposed SIP revisions would incorporate a PSD rule for the VCAPCD into the SIP to establish a PSD permit program for pre-construction review of certain new and modified major stationary sources in attainment and unclassifiable areas within the District. We are taking public comments on this proposal and plan to follow with a final action following consideration of the public comments received.
