## Abstract

EPA is taking direct final action to approve revisions to the San Diego County Air Pollution Control District Operating Permits (Title V) Program. Under authority of the Clean Air Act as amended in 1990 (CAA or the Act), we are approving a rule revision that addresses a change in the major source threshold for volatile organic compounds (VOCs) and oxides of nitrogen (NO<INF>X</INF>). This change is based on the redesignation of San Diego County as in attainment of the federal one-hour ozone standard. As a result of this action, some sources that would have previously been considered major sources, and therefore would have been required to obtain a Title V operating permit, would no longer need to apply for a Title V permit. We are also approving revisions to several other parts of San Diego's Title V program. For more information see "What is being addressed in this document," below.
