Once large infrastructure projects, such as oil and natural gas pipelines, receive federal government approval, they are often the target of legal challenges from opposition groups. Opponents repeatedly argue that the environmental review, pursuant to the National Environmental Policy Act (NEPA), was insufficient. If a court finds deficiencies in the government’s NEPA analysis, can a court halt construction or cease operations even after years of project design, permit approvals at all levels of government, and tens of millions of dollars in investment? This question was at the heart of the ongoing litigation involving the controversial Dakota Access Pipeline (DAPL), and, on October 11, Judge James Boasberg determined “no,” the court would not shut down the pipeline. This case is important precedent for projects being challenged under NEPA. The same issue is at play in the Sabal Trail case currently under review by the US Court of Appeals for the DC Circuit. See Sierra Club, et al. v. FERC, No. 16-1329 (D.C. Cir. filed Sept. 21, 2016).
Despite oil already flowing through the pipeline, federal litigation involving the controversial Dakota Access Pipeline (DAPL) took another turn last week when partial summary judgment was granted to tribes challenging the adequacy of the US Army Corps of Engineers’ review of DAPL under the National Environmental Policy Act (NEPA) and other statutes. Two tribes, the Standing Rock Sioux Tribe and the Cheyenne River Sioux Tribe, filed suit in July 2016 attempting to block construction of the last remaining segment and operation of DAPL. As sometimes is the case, agency approvals came faster than the court’s opinion, and without a stay of proceedings DAPL began operating in early June 2017. Having granted partial summary judgment, the court did not require pipeline operations to cease, instead delaying the question of an appropriate remedy until after further briefing by the parties.
On September 29, 2015, the D.C. Circuit Court of Appeals ruled that the National Environmental Policy Act (NEPA) did not require federal agencies authorizing portions of an interstate oil pipeline project to conduct a “whole-pipeline” environmental review. The case, Sierra Club v. U.S. Army Corps of Engineers, et al., clarifies the appropriate scope of NEPA review for oil pipeline construction projects where federal involvement is limited to granting authorizations for discrete aspects of the project.
