A federal judge has overturned an Obama administration effort to reverse a Bush administration rule that’s made it easier for coal mining companies to dump mountaintop debris into valley streams. The administration had asked the court to withdraw the Bush regulation, which came into effect late last year. But on Wednesday, Judge Henry Kennedy said the overhaul should be subjected to public input. In a statement, the Sierra Club called for policy changes at the Army Corps of Engineers, the Department of Interior and the Environmental Protection Agency, in order “to end the destruction completely and protect Appalachian communities.”
