On May 29, 2025, the U.S. Supreme Court issued a significant decision clarifying the scope of environmental review required under the National Environmental Policy Act (“NEPA”) for major infrastructure projects. The Court recognized and reined in what infrastructure practitioners have long understood: NEPA strayed far beyond its “procedural” and “informational” roots to become an obstruction to infrastructure projects across the country.

As brief background, a project developer filed an application with the Surface Transportation Board (“STB”) for a proposed 88-mile railroad line in Utah. The STB, pursuant to its NEPA requirements, issued a 3,600-page environmental impact statement (“EIS”) analyzing the environmental effects of the project and ultimately approved the railroad line. Groups challenged the STB’s approval, and the D.C. Circuit vacated the STB’s decision, ordering the STB to analyze the potential “upstream” impacts of the proposed railroad, which included possible increased oil and gas drilling activities in Utah, and potential “downstream” impacts of the railroad, such as increased oil refining in Texas.

The Supreme Court reversed the D.C. Circuit Court’s prior decision, finding that the D.C. Circuit: (1) did not afford substantial deference to the STB required in NEPA cases, and (2) incorrectly ordered the STB to review the environmental effects of projects separate in time and place from the actual 88-mile railroad under consideration.
