## Abstract

On April 17, 2015, the Environmental Protection Agency (EPA or the Agency) promulgated national minimum criteria for existing and new coal combustion residuals (CCR) landfills and existing and new CCR surface impoundments. On August 21, 2018, the U.S. Court of Appeals for the D.C. Circuit issued its opinion in the case of Utility Solid Waste Activities Group v. EPA, 901 F.3d 414 (per curiam) (USWAG). This rule finalizes regulations proposed on March 3, 2020, including procedures to allow facilities to request approval to operate an existing CCR surface impoundment with an alternate liner, among other things. Provisions from the proposed rule that are not addressed in this rule will be addressed in a subsequent action.
