Abstract

The CAA Amendments of 1977 require EPA to review and, if appropriate, revise air quality criteria primary (health-based) and secondary (welfare-based) NAAQS periodically. On October 11, 1995, EPA published a final rule not to revise either the primary or secondary NAAQS for NO2. That action provided the Administrator's final determination, after careful evaluation of comments received on the October 1995 proposal, that revisions to neither the primary nor the secondary NAAQS for NO2 were appropriate at that time. On December 9, 2005, EPA/ORD initiated the current periodic review of NO2 air quality criteria, the scientific basis for the NAAQS, with a call for information in the FR. (This regulatory action is for the Agency's review of the primary NO2 NAAQS. Review of the secondary NO2 NAAQS will be part of a separate regulatory action combined with review of the sulfur dioxide NAAQS.) The EPA's ORD and OAR will prepare a plan for the primary NO2 NAAQS review, which will be an integrated plan for addressing policy-relevant scientific and technical issues and will include a schedule fo the review. Subequently, a Science Assessment and a Policy Assessment will be prepared jointly by ORD and OAR. The Policy Assessment will evaluate the policy implications of key information contained in the Science Assessment, as well as any appropriate technical analyses. These documents will be reviewed by the CASAC, an independent science advisory committee established to review the scientific and technical basis of the NAAQS, and the public, and both final documents will reflect the input received through these reviews. As the primary NO2 NAAQS review is completed, the Administrator's proposal to retain or revise the NO2 NAAQS will be published with a request for public comment. Input received during the public comment period will be considered in the Administrator's final decision.
