Riepilogo

EPA is notifying the public that it has found that the motor vehicle emissions budgets (MVEBs) for Shelby County, Tennessee in the 1997 8-Hour Ozone Maintenance Plan State Implementation Plan (SIP) revision, submitted on February 26, 2009, by the Tennessee Department of Environment and Conservation (TDEC), are adequate for transportation conformity purposes. Shelby County is one of the counties in the bi- state Memphis Area for the 1997 8-hour ozone standard. Crittenden County, Arkansas is the other county in the bi-state Memphis Area. Through a separate action EPA has already found the Crittenden County budgets adequate for transportation conformity purposes. This action relates only to the Shelby County, Tennessee budgets. As a result of EPA's finding, Shelby County must use the MVEBs for future conformity determinations for the 1997 8-hour ozone standard.
