## Abstract

On October 27, 2003 and December 24, 2003, the EPA revised regulations governing the major New Source Review (NSR) programs mandated by parts C and D of title I of the Clean Air Act (CAA or Act). Following these two actions, the Administrator received petitions for reconsideration from a collection of environmental and public interest groups and a group of states. Today, we, the EPA, are announcing our reconsideration of certain issues arising from the final rules of October 27, 2003 and December 24, 2003. We are requesting public comment on three issues as to which we are granting reconsideration. The issues are described in section II of this notice. We plan to issue a final decision on these issues and other issues raised in the various petitions by December 28, 2004. We are only seeking comment on provisions of the major NSR rules as specifically identified in this notice. We will not respond to any comments addressing any other provisions of the NSR rules or program.
