The U.S. Supreme Court has struck down an appeals court ruling that would have blocked construction of the Atlantic Coast Pipeline beneath the Appalachian Trail. The Richmond Times-Dispatch reports that the court voted 7-2 to overturn the ruling by the 4th U.S Circuit Court of Appeals, based in Richmond. The ruling will allow construction of the 42-inch-wide pipeline to tunnel beneath the A-T in the George Washington National Forest. The decision will also enable Dominion Resources and its partners to cross the Blue Ridge between Augusta and Nelson counties to complete the $8 billion, 600-mile project.
