What is an EIS?

EIS is an acronym for Environmental Impact Statement. An EIS is a clear, concise, and appropriately detailed document that provides the agency decision makers and the public with a full and fair discussion of the significant environmental impacts of the Proposed Action and reasonable alternatives.

An EIS is a detailed written statement required under NEPA when one or more environmental impacts would be significant and mitigation measures cannot reduce the impact(s) below significant levels. Direct, indirect, and cumulative impacts must be considered when determining significance.
