Approval and Promulgation of Implementation Plans; Ohio; Volatile Organic Compound Emission Control Measures for Cincinnati and Dayton

The EPA is approving several volatile organic compound (VOC) rules, that were submitted on May 9, 2006, into the Ohio State Implementation Plan (SIP). These rules would partially replace the VOC reductions from Ohio's vehicle inspection and maintenance (E-Check) program (which ended on December 31, 2005) in the Cincinnati and Dayton areas. These rules include a provision requiring the use of lower emitting solvents in cold cleaner degreasers, the use of more efficient auto refinishing painting application techniques and a rule requiring the use of lower emitting portable fuel containers. These rules are approvable because they contain more stringent requirements than Ohio's existing rules and they are enforceable. Ohio has correctly calculated their VOC emission reduction impact. EPA is also approving several other rule revisions, all of which meet EPA requirements, including an exemption for Ohio's printing rules, a site-specific rule for an aerosol can filling facility, elimination of the fluid catalytic cracking unit limitations for a Marathon Petroleum LLC facility, and an alternative leak detection and repair program for the Premcor Lima Refinery. These rules were proposed for approval on December 6, 2006, and no adverse comments were received.
