Approval and Promulgation of Air Quality Implementation Plans; Commonwealth of Pennsylvania; Reasonably Available Control Technology Requirements for Volatile Organic Compounds and Nitrogen Oxides

EPA is removing the conditional status of its approval of the Commonwealth of Pennsylvania State Implementation Plan (SIP) revision that requires all major sources of volatile organic compounds (VOCs) and nitrogen oxides (NO<INF>X</INF>) to implement reasonably available control technology (RACT). Pennsylvania has satisfied the condition imposed in EPA's conditional limited approval published on March 23, 1998 (63 FR 13789). The intended effect of this action is to remove the conditional nature of EPA's approval of Pennsylvania's VOC and NO<INF>X</INF> RACT Regulation. The regulation retains its limited approval status. Conversion of the Pennsylvania VOC and NO<INF>X</INF> RACT Regulation from limited to full approval will occur when EPA has approved the case-by-case RACT determinations submitted by Pennsylvania.
