## Abstract

EPA is converting its limited approval of a State Implementation Plan (SIP) revision submitted by the Commonwealth of Pennsylvania consisting of regulations that require all major sources of volatile organic compounds (VOC) and nitrogen oxides (NO<INF>X</INF>) to implement reasonably available control technology (RACT) to a full approval as they apply throughout the Commonwealth. In prior final rules, EPA has fully approved Pennsylvania's VOC and NO<INF>X</INF> RACT regulations for the Pennsylvania portion of the Philadelphia-Wilmington-Trenton area, and for the Pittsburgh-Beaver Valley area. The intended effect of this action is to convert EPA's limited approval of Pennsylvania's VOC and NO<INF>X</INF> RACT regulations to full approval as they apply throughout the remainder of the Commonwealth. This action is being taken under the Clean Air Act (CAA or the Act).
