## Abstract

The Environmental Protection Agency (EPA) is taking final action 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. We are approving SIP revisions that 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.
