Oral arguments will be heard this morning beginning at 10 am at the U.S. Supreme Court on a case to decide whether or not the Appalachian Trail will, from now on, block all future pipelines from being installed under it. The case, U.S. Forest Service v. Cowpasture River Preservation Association, will determine whether or not Big Green wins the right to block Dominion Energy’s Atlantic Coast Pipeline (ACP) project from crossing under the Appalachian Trail.
