(3/3/06) EPA, in consultation with U.S. Department of Transportation, finalized procedures to help state and local transportation and air quality agencies ensure that future transportation projects support state and local efforts to meet and maintain federal air quality standards for fine (PM 2.5) and coarse (PM10) particles. The final rule provides criteria for determining which transportation projects must be analyzed for local particle emissions impacts in PM2.5 and PM10 nonattainment and maintenance areas. This project-level analysis will allow transportation project sponsors to project future air quality impacts that will result from their transportation project.
