What is NEPA?

The National Environmental Policy Act of 1969 (NEPA) is a federal environmental law that established processes to evaluate the needs and benefits of a federal action and the potential environmental impacts arising from the action. The law requires development of a reasonable range of project alternatives that can accomplish the purpose and need, and consideration of potential impacts to socioeconomic, cultural, and natural resources from the alternatives being considered. Key to this process is coordination among federal, state, and local agencies, and communication with the public, and other project stakeholders.
