The U.S. Supreme Court, 8-0, held that the D.C. Circuit failed to afford the Surface Transportation Board the substantial deference NEPA requires in a challenge to the Board's authorization of a new 88-mile rail line in the Uinta Basin, and that the court incorrectly interpreted NEPA to require the Board to consider environmental effects of upstream and downstream projects that were separate in time and place from the rail line. Environmental groups and a Colorado county petitioned for review of the authorization, arguing the Board failed to take a "hard look" at the impacts. The D.C. Circuit held the Board impermissibly limited its analysis of environmental effects from upstream oil drilling and downstream oil refining projects, concluding those were reasonably foreseeable impacts the EIS should have analyzed more extensively; it vacated both the EIS and the Board's final approval order. The Supreme Court held that courts, when determining whether an EIS complies with NEPA, should afford substantial deference to the agency, and that as long as the EIS addressed environmental effects from the project at issue, courts should defer to agencies' decisions about where to draw the line when considering indirect environmental effects and whether to analyze effects from other projects separate in time and place from the project at issue. Here, the Board's determination not to address environmental effects of upstream oil drilling and downstream oil refining projects complied with NEPA; the EIS needed only to address the effects of the new rail line and did so. The Court reversed and remanded for further proceedings. Kavanaugh, J., delivered the opinion of the Court, in which Roberts, C.J., and Thomas, Alito, and Barrett, JJ., joined. Sotomayor, J., filed an opinion concurring in the judgment, in which Kagan and Jackson, JJ., joined. Gorsuch, J., took no part in the consideration or decision of the case.
