Standing Rock Sioux Tribe v. United States Army Corps of Engineers, No. 20-5197 (D.C. Cir. 2021)Annotate this Case
The DC Circuit held that the Corps violated the National Environmental Policy Act (EPA) by issuing an easement allowing the Dakota Access Pipeline to transport crude oil through federally owned land at the Lake Oahe crossing site without preparing an environmental impact statement despite substantial criticisms from the Tribes.
The court rejected the Corps' and Dakota Access' contention that the district court applied the wrong standard by relying on National Parks Conservation Association v. Semonite, 916 F.3d at 1083, which emphasized the important role played by entities other than the federal government. The court explained that the Tribes' unique role and their government-to-government relationship with the United States demand that their criticisms be treated with appropriate solicitude. The court concluded that several serious scientific disputes in this case means that the effects of the Corps' easement decision are likely to be "highly controversial." The court also noted that, although the risk of a pipeline leak may be low, that risk is sufficient that a person of ordinary prudence would take it into account in reaching a decision to approve the pipeline's placement, and its potential consequences are therefore properly considered. The court affirmed the district court's order vacating the easement while the Corps prepares an environmental impact statement. However, the court reversed the district court's order to the extent it directed that the pipeline be shut down and emptied of oil.
