A federal court has once again struck down crucial permitting for the Mountain Valley Pipeline’s crossing of Jefferson National Forest, according to Natural Gas Intelligence.

Earlier this week, the U.S. Court of Appeals for the Fourth Circuit vacated and remanded key authorizations issued to the project by the U.S. Forest Service and the Bureau of Land Management that would have allowed it to cross a 3.5-mile stretch of national forest land along the Virginia and West Virginia border.

The court found that the federal agencies erred by failing to account for data showing the erosion impacts of the project and by “prematurely” authorizing the conventional bore method for four stream crossings within the national forest. Additionally, they failed to comply with a 2012 forest planning rule.
