Argument Analysis: The Trail, the Pipeline, and a Journey to the Center of the Earth

Environmental groups faced a skeptical bench during Monday's argument in two consolidated cases, U.S. Forest Service v. Cowpasture River Preservation Association and Atlantic Coast Pipeline LLC v. Cowpasture River Preservation Association, as they fought to preserve a 2018 decision from the U.S. Court of Appeals for the 4th Circuit that had halted an $8 billion, 600-mile natural gas pipeline. At the heart of the dispute is a 2017 permit granted by the U.S. Forest Service to allow the Atlantic Coast Pipeline to cross the George Washington National Forest. The permit also authorized the developers to tunnel 600 feet beneath the Appalachian Trail within the forest. Vacating the permit, the 4th Circuit held that the entire 2,100-mile Appalachian Trail is part of the National Park System and therefore, under the Mineral Leasing Act, the trail is off-limits for energy development and pipeline rights-of-way.
