Friends of the Inyo v. United States Forest Service

Friends of the Inyo v. United States Forest Service provides necessary guidance for categorical exclusion analysis under the National Environmental Policy Act. The Ninth Circuit Court of Appeals held that the United States Forest Service wrongfully construed NEPA as permissive of applying different categorical exclusions to various components of the same mining project until the project was excluded in its entirety from further environmental review. The Court’s holding establishes two essential rules for evaluating mining proposals on public lands: (1) a categorical exclusion, when applied under § 220.6, must cover the entire scope of a proposed project; and (2) the scope of a mining project proposed on USFS land includes environmental mitigation efforts.
