scope:

SUMMARY: EPA is proposing to approve a State Implementation Plan (SIP) revision submitted by the State of Ohio on February 14, 2006 and October 6, 2006, establishing a lower Reid Vapor Pressure (RVP) fuel requirement for gasoline distributed in the Cincinnati and Dayton 8-hour ozone nonattainment areas. Ohio has developed these fuel requirements to reduce emissions of volatile organic compounds (VOC) in accordance with the requirements of the Clean Air Act (CAA). EPA is proposing to approve Ohio's fuel requirements into the Ohio SIP because EPA has found that the requirements are necessary for the Cincinnati and Dayton areas to achieve the 8-hour ozone national ambient air quality standard (NAAQS). This action is being taken under section 110 of the CAA.
