Approval and Promulgation of Air Quality Implementation Plans; Pennsylvania; Control of Volatile Organic Compound Emissions From Fiberglass Boat Manufacturing Materials

The Environmental Protection Agency (EPA) is proposing to approve a revision to the Pennsylvania state implementation plan (SIP) submitted by the Commonwealth of Pennsylvania. This SIP revision pertains to Pennsylvania's regulation for fiberglass boat manufacturing materials found in section 129.74 of the Pennsylvania Code. This regulation meets the requirement to adopt reasonably available control technology (RACT) for sources covered by EPA's control techniques guidelines (CTG) standards for fiberglass boat manufacturing materials. EPA is, therefore, proposing approval of the revision to the Pennsylvania SIP in accordance with the requirements of the Clean Air Act (CAA).
