## Abstract

The EPA is amending its regulations to eliminate the pollution control project (PCP) and clean unit (CU) provisions included in its December 31, 2002 rulemaking entitled "Prevention of Significant Deterioration (PSD) and Nonattainment New Source Review (NSR): Baseline Emissions Determination, Actual-to-future-actual Methodology, Plantwide Applicability Limitations, Clean Units, Pollution Control Projects." This final rule conforms the regulations to the decision by the U.S. Court of Appeals for the D.C. Circuit, New York v. EPA, 413 F.3d 3 (D.C. Cir. 2005), vacating the PCP and CU provisions. This action is exempt from notice-and-comment rulemaking because it is ministerial in nature.
