The National Mining Association and the Utility Solid Waste Activities Group asked the U.S. District Court for the District of Columbia October 25 to reject requests from environmental groups and coal ash recyclers for a firm time frame for the completion of the Environmental Protection Agency’s rulemaking on coal ash. The groups charge that the agency did not meet a six-year statute of limitations applicable to civil action against the United States and that the agency had met its statutory obligations for review of management practices. Environmental groups filed the lawsuit April 5 asking the court to compel the agency to issue a final rule within six months.
