EPA is amending the transportation conformity rule to finalize provisions that were proposed on August 13, 2010. These amendments restructure several sections of the transportation conformity rule so that they apply to any new or revised National Ambient Air Quality Standards. EPA is also finalizing several clarifications to improve implementation of the rule. EPA is not taking a final action at this time on the proposal that areas analyze a near-term analysis year when using the budget test. The Clean Air Act requires federally supported transportation plans, transportation improvement programs, and projects to be consistent with (conform to) the purpose of the state air quality implementation plan. EPA consulted with the U.S. Department of Transportation and they concur in the development of this final rule.
