EPA Repeals the Clean Power Plan and Finalizes Affordable Clean Energy Rule [Updated October 4, 2019] [open pdf - 537KB]
From the Document: "The U.S. Environmental Protection Agency (EPA) finalized its repeal of the Clean Power Plan (CPP) and promulgated new emissions guidelines in the Affordable Clean Energy (ACE) rule. EPA based these actions on its conclusion that the CPP exceeded Clean Air Act (CAA) authority by using measures that applied to the power sector as a whole rather than measures carried out within an individual facility. Among other things, the final ACE rule establishes efficiency improvements as the 'best system of emission reduction' (BSER) for existing coal-fired power plant greenhouse gas (GHG) emissions. Stakeholder views range from agreement with EPA's interpretation of its CAA authority and its BSER determination to legal challenges of the rule. In August 2019, some states and nongovernmental organizations filed petitions challenging the rule in the D.C. Circuit. This Insight summarizes the rulemaking and discusses potential considerations for Congress."
