U.S. Chamber Comments to EPA on MATS Reconsideration Proposal

April 17, 2019

Dear Administrator Wheeler:

The U.S. Chamber of Commerce (“the Chamber”) appreciates the opportunity to comment on the U.S. Environmental Protection Agency’s (“EPA”) proposed reconsideration of its response to the U.S. Supreme Court’s decision in Michigan v. Environmental Protection Agency. The proposal addresses EPA’s consideration of cost in its 2012 and 2016 determinations that regulation under section 112 of the Clean Air Act (“CAA”) of hazardous air pollutant (“HAP”) emissions from coal- and oil-fired electric utility steam generating units (“EGUs”) was “appropriate and necessary.”
