The U.S. Court of Appeals for the Fourth Circuit on Oct. 2 ordered another halt to construction activity on all portions of the Mountain Valley natural gas pipeline. The court ruled that the Army Corps of Engineers had instituted inadequate requirements for how the pipeline should cross streams in West Virginia, just a few weeks after some sections had resumed construction. In July, the court decided that the U.S. Bureau of Land Management had approved the route across the Jefferson National Forest in southern Virginia without adequate study, and that the U.S. Forest Service improperly concluded that impacts of the pipeline could be mitigated. The troubled pipeline would supply up to two million dekatherms per day of natural gas to markets in the Mid- and South Atlantic regions. The $3-billion project is a joint venture of EQT Midstream Partners LP, NextEra US Gas Assets LLC, Con Edison Transmission Inc., WGL Midstream, and RGC Midstream LLC.
