View Rule

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 United States Court of Appeals for the District of Columbia Circuit  vacated the exemption for inactive impoundments at inactive facilities (legacy CCR surface impoundments) and remanded the issue back to EPA to take further action consistent with its opinion in Utility Solid Waste Activities Group, et al, v. EPA . This action responded to that order and established regulatory requirements  for legacy CCR surface impoundments. EPA also established  requirements for CCR management units at active CCR facilities and inactive CCR facilities with a legacy CCR surface impoundment. EPA also made several technical corrections to the existing regulations, including correcting certain citations and harmonizing definitions.
