What is an environmental impact statement (‘eis’)?
The EIS picks up where the environmental assessment report left off. Prepared internally by the federal agency or contracted to an outside firm, it more rigorously both the positive and negative impact the federal project can reasonably have on the environment. The report covers a myriad of federal projects – constructing oil refineries, large reservoirs, urban renewal, offshore drilling, highways, sewage treatment plants, dams, etc. It identifies the direct and indirect foreseeable effects, the conflicts with local or state policies. The report must include the objections of other federal, state, and local agencies, special interest organizations and the public which were received during the review process. The agency must explain where its information came from and how it arrived at its conclusions.
