What is a NEPA environmental review?NEPA

The National Environmental Policy Act (NEPA) of 1969 requires that the effects on the environment be evaluated and reasonable alternatives to those actions be identified prior to the approval of any major federal actions or federal permitting.  The Environmental Protection Agency's (EPA) review and assessment of environmental information relating to the project, including any applicable public review and the determination of a categorical exclusion (CATEX), or the development of an environmental assessment/finding of no significant impact (EA/FONSI), or an environmental impact statement/record of decision (EIS/ROD) is called the NEPA environmental review. If a project is not eligible for a CATEX, NEPA requires EPA to prepare either an EA or EIS on the proposed project.

In order for EPA to prepare either an EA or EIS, it needs environmental information about the proposed project. The applicant provides EPA with this project information to help assess the potential environmental effects of the proposed project and alternatives to the proposed project. Typically, EPA refers to this documentation as the Environmental Information Document (EID). The EID should contain adequate information for EPA to conduct an environmental review.

NEPA and its implementing regulations provide the framework that is used to evaluateEnvironmental a proposed action, consider all of the reasonable alternatives and no action, and assess the potential environmental effects of the proposed action and alternatives.  NEPA also requires integrating analyses and consultations undertaken pursuant to other environmental laws and executive orders to the maximum extent possible with the
NEPA environmental review process. These environmental laws and Executive Orders are commonly referred to as “cross-cutters.” To comply with cross-cutting federal laws and Executive Orders, it is often necessary to provide the cross-cutter agency the opportunity to review and provide input (or concurrence) through consultation and coordination on the proposed project. Beginning this process early in the project may help avoid delays.
