Supreme Court Ruling Narrows NEPA
On Thursday, May 29, 2025, the US Supreme Court issued an 8-0 decision in Seven County Infrastructure Coalition v. Eagle County, narrowing the scope of environmental review under the National Environmental Policy Act (NEPA). This ruling may have implications for water projects involving new dams, dam expansions, river intakes, and transmission pipelines. These projects typically undergo NEPA review, and the Supreme Court’s recent decision could alter both the extent and process of environmental assessments moving forward.
