On April 17, 2015, the EPA 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 D.C. Circuit Court of Appeals issued its opinion in the case of Utility Solid Waste Activities Group, et al v. EPA. In July 2018, EPA amended pieces of the 2015 final rule. Environmental groups challenged that rule and on March 13, 2019, the DC District Court allowed a voluntary remand without vacatur. This rule will propose a new cease receipt of the October 2020 waste deadline and address some issues from the August 2018 court decision.
