On July 29, EPA Administrator Andrew Wheeler signed a long-anticipated proposal to amend EPA’s 2015 Coal Combustion Residuals (CCR) rule.
EPA’s proposal includes a number of changes, including the establishment of an alternate risk-based groundwater protection standard for boron, revisions to the annual groundwater monitoring and corrective action report requirements, and revisions to the CCR website requirements. The proposal also includes changes in response to the U.S. Court of Appeals for the D.C. Circuit’s August 21, 2018 remand of certain CCR rule provisions. These amendments address the “beneficial use” definition and CCR pile requirements.
