The Environmental Protection Agency (EPA) is amending its Prevention of Significant Deterioration (PSD) and title V regulations to remove from the Code of Federal Regulations portions of those regulations that were initially promulgated in 2010 and that the Court of Appeals for the District of Columbia Circuit (D.C. Circuit) specifically identified as vacated in the April 10, 2015, amended judgment, Coalition for Responsible Regulation v. EPA. This action is exempt from notice-and-comment rulemaking because it is ministerial in nature.
