In 2022, the DC Circuit Court of Appeals decided the case Oglala Sioux Tribe v. United States Nuclear Regulatory Commission. Like similar cases, the plaintiffs, the Oglala Sioux, challenged a US federal agency, the Nuclear Regulatory Commission, over their granting of a permit to an industrial project, in this case a uranium mining project. The Oglala Sioux argued that the agency’s environmental impact statement (EIS) was incomplete and inadequate. The court rejected the Oglala Sioux’s arguments, decided that the EIS was sufficient, and ruled in favor of the Nuclear Regulatory Commission. Critically, even though the agency did not follow EIS procedures completely, the court applied several exemptions allowing the EIS to stand. As in other EIS cases in recent years, Oglala Sioux highlights the limitations of environmental law in the protection of US communities’ local environments and cultural heritage.
