The National Environmental Policy Act (NEPA) articulated the national environmental policy, established federal agency responsibility and created the basis or foundation of the federal decisionmaking process. The fundamentals of the NEPA decisionmaking process include: consideration of alternatives, examination of potential environmental impacts and mitigation, interagency coordination, public involvement and documentation.

This Topic Area is focused on the NEPA process and documentation. This includes the specific requirements for categorical exclusions (CEs), environmental assessments (EAs), findings of no significant impact (FONSIs), environmental impact statements (EISs), and records of decisions (RODs).
