Appeals Court Upholds EPA Block on W.Va. Mine The U.S. Environmental Protection Agency had the legal authority to retroactively veto a water pollution permit for one of West Virginia's largest mountaintop removal coal mines years after it was issued, a federal appeals court ruled Tuesday. The U.S. Court of Appeals for the District of Columbia reversed a lower court's ruling in a case that has economic implications across coal country and potentially the nation. The case goes back to U.S. District Court for further proceedings. The appellate court directed Judge Amy Berman Jackson to address the coal industry's argument that the EPA's action was an "arbitrary and capricious" violation of the Administrative Procedure Act, an issue she has not previously ruled on. The holder of the permit, St. Louis-based Arch Coal, didn't immediately comment on the latest ruling. In January 2011, the EPA revoked a permit that the U.S. Army Corps of Engineers had issued four years earlier to Arch and its Mingo Logan Coal Co. subsidiary. The EPA concluded that destructive and unsustainable mining practices at the 2,300-acre Logan County mine would cause irreparable environmental damage and threaten the health of communities nearby. Jackson later ruled that EPA had overstepped its authority by revoking a permit that had been thoroughly reviewed and properly issued by the corps. Her ruling was panned by environmentalists and widely praised by coalfields politicians, both Democrats and Republicans who regularly complain about what they describe as a "war on coal" by the Obama administration. Coal companies and other industries argued that the EPA's maneuver effectively such prevents permits from ever being considered final, and that could have a chilling effect on new construction and economic development nationwide Mountaintop removal is a highly efficient but destructive form of strip mining that blasts apart mountain ridge tops to expose multiple coal seams. The resulting rock and debris is dumped in streams, creating so-called valley fills. Spruce No. 1 would have buried nearly 7 miles of streams. It was only the 13th time since 1972 that the EPA had used the veto authority and the first time it had acted on a previously permitted mine. The agency said it reserves the power for rare and unacceptable cases, but Jackson declared the action "incorrect and unreasonable."
