Determination of Attainment, Approval and Promulgation of Implementation Plans and Designation of Areas for Air Quality Planning Purposes; Ohio; Redesignation of the Toledo Area 8-Hour Ozone Nonattainment Area to Attainment

The Ohio Environmental Protection Agency (Ohio EPA) submitted a request on December 22, 2006, and supplemented it on March 9, 2007, for redesignation of the Toledo, Ohio area (Lucas and Wood Counties) to attainment for the 8-hour ozone standard. The submission also includes a maintenance plan that provides for continued attainment through 2018. On June 12, 2007, EPA proposed to approve this submission. EPA provided a 30-day review and comment period. One comment, from BP Products, North America Inc., was received supporting EPA's proposal. Today, EPA is approving Ohio's request and corresponding State Implementation Plan (SIP) revision. In so doing, EPA is making a determination that the Toledo, Ohio area has attained the 8-hour ozone National Ambient Air Quality Standard (NAAQS). This determination is based on three years of complete, quality-assured ambient air quality monitoring data for the 2004-2006 ozone seasons that demonstrate that the 8-hour ozone NAAQS has been attained in the area. Preliminary 2007 air quality data show that the area continues to attain the 8-hour ozone standard. EPA is approving the maintenance plan for this area and is redesignating the area to attainment. Finally, EPA is approving, for purposes of transportation conformity, the motor vehicle emission budgets (MVEBs) for the years 2009 and 2018.
