## Abstract

EPA issued a final rule on July 1, 2004 (69 FR 40004) that amended the transportation conformity rule to include criteria and procedures for the new 8-hour ozone and fine particulate matter (PM<INF>2.5</INF>) national ambient air quality standards (NAAQS or "standards"). The final rule also addressed a March 2, 1999 ruling by the U.S. Court of Appeals for the District of Columbia Circuit (Environmental Defense Fund v. EPA, et al., 167 F. 3d 641, D.C. Cir. 1999). The preamble to the final rule contains two errors. This notice is intended to correct these errors. All other preamble and regulatory text printed in the July 1, 2004 final rule is correct. The Department of Transportation (DOT) is EPA's federal partner in implementing the transportation conformity regulation. We have consulted with DOT on the development of these corrections, and DOT concurs.
