The National Environmental Policy Act (NEPA)(link is external) applies to “every major Federal action significantly affecting the quality of the human environment” (42 U.S.C. § 4332(1)(C)(link is external)). NEPA requires that agencies undertake an environmental analysis to determine whether a federal action has the potential to cause significant environmental effects. If a proposed major federal action is determined to significantly affect the quality of the human environment, Federal agencies are required to prepare an Environmental Impact Statement (EIS),a more detailed and rigorous than the requirements for an Environmental Assessment (EA).
