In addition, EPA is approving the Commonwealth's request to change the status of Mead Township and Clarendon Borough in Warren County from unclassifiable to attainment of the NAAQS for SO<INF>2</INF>. EPA is also approving the maintenance plan for these areas submitted by the Commonwealth as a revision to the Pennsylvania State Implementation Plan (SIP). This plan provides for the maintenance of the NAAQS for SO<INF>2</INF> for the next ten years. These actions are being taken in accordance with the Clean Air Act (CAA).
