Environmental Assessments (EA) / Environmental Impact Statements (EIS)

Environmental Assessments are concise public documents that a Federal agency prepares under NEPA to provide sufficient evidence and analysis to determine whether a proposed agency action would require preparation of an environmental impact statement or a finding of no significant impact.

Environmental Impact Statements are detailed written statements that are required by section 102(2)(C) of NEPA for a proposed major Federal action significantly affecting the quality of the human environment.
