## Abstract

EPA is finalizing approval of the redesignation of the 1-hour ozone National Ambient Air Quality Standard (NAAQS) nonattainment area of Birmingham, Alabama, to attainment, and finalizing approval of Alabama's State Implementation Plan (SIP) revision containing a 10-year maintenance plan for the 1-hour ozone NAAQS for the Birmingham area. Additionally, through this action, EPA is providing notification of its determination that the motor vehicle emission budgets (MVEBs) for the year 2015 contained in the 10-year maintenance plan SIP revision for the 1-hour ozone standard for the Birmingham area (submitted on January 30, 2004, by the Alabama Department of Environmental Management (ADEM)), are adequate for transportation conformity purposes. Because EPA is approving these 2015 MVEBs as part of its approval of Alabama's 10-year maintenance plan SIP revision for the Birmingham area, the 2015 MVEBs contained in the Birmingham area's 10-year maintenance plan for the 1-hour ozone standard, can be used for future conformity determinations on the date of publication of this Final rule.
