Approval and Promulgation of Air Quality Implementation Plans; Commonwealth of Pennsylvania; RACT for VOC's From Synthetic Organic Chemical Manufacturing Industries (SOCMI) in Allegheny County

الملخص

EPA is taking a limited approval/limited disapproval on a State Implementation Plan (SIP) revision submitted by the Pennsylvania Department of Environmental Resources (PADER). This revision establishes and requires reasonably available control technology (RACT) to control fugitive volatile organic compounds (VOC) emissions from Synthetic Organic Chemical and Polymer Manufacturing-Fugitive Sources (SOCMI) and the associated test method required to determine compliance. This revision has been submitted by the PADER at the request of the Allegheny County Bureau of Air Pollution Control (BAPC) to fulfill its 1982 ozone SIP commitment to adopt all applicable control technique guidelines (CTG's) published by EPA. The intended effect of this document is to take limited approval action on the revision because the regulation strengthens the SIP. At the same time, EPA is taking limited disapproval action on this revision because it does not fully meet the Federal SIP requirements. Furthermore, the limited disapproval action initiates the 18-month sanction clock and the 24-month Federal implementation plan (FIP) period. These actions are being taken under the Clean Air Act (CAA).
