transportation conformity rule : PM2.5 and PM10 amendments
Office of Transportation and Air Quality.
The U.S. Environmental Protection Agency (EPA) is proposing changes to the transportation conformity rule that primarily concern conformity's implementation in PM2.5 and PM10 nonattainment and maintenance areas. EPA is proposing to update the transportation conformity regulation in light of the October 17, 2006 final rule that strengthened the 24-hour PM2.5 standard and revoked the annual PM10 standard. EPA is also proposing to clarify the regulations concerning project-level air quality analyses to address a court's remand of the transportation conformity hot-spot requirements for further explanation.
