Approval and Promulgation of Air Quality Implementation Plans; Colorado; Revisions to Regulation No's. 3 and 7 for Pioneer Metal Finishing Inc. and a Revision to Regulation No. 7 for Lexmark International Inc.

EPA is approving the revisions to the Colorado State Implementation Plan (SIP) as submitted by the Governor on August 25, 1995, and October 16, 1995. The revisions consist of amendments to Regulation No. 3, ``Air Contaminant Emissions Notices,'' and Regulation No. 7, ``Regulation To Control Emissions of Volatile Organic Compounds.'' The revisions to Regulations Nos. 3 and 7 for Pioneer Metal Finishing Inc. (PMF) consist of a source-specific SIP revision to allow PMF to purchase banked Volatile Organic Compound (VOC) emission reduction credits (ERC) from Coors Brewing Company (Coors), to enable PMF to come into compliance with the VOC Reasonable Available Control Technology (RACT) requirements of Regulation No. 7 (Reg. 7). The revision to Reg. 7 for Lexmark International Inc. (Lexmark) consists of a source-specific SIP revision to allow Lexmark to utilize the provisions of Reg. 7 to perform crossline averaging for the purposes of meeting the VOC RACT requirements of Reg. 7. This Federal Register action applies to both of these submittals. EPA's approval will serve to make these revisions federally enforceable and was requested by the State of Colorado.
