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 AT 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.
