Environmental Impact Statements (EISs) are a type of public review document. They are made available to the public for review. The public is expected to comment on the content of the document during a “public review period.”
The National Environmental Policy Act (NEPA) requires environmental impact statements (EISs) for projects that will significantly impact the human environment. Smaller projects may only require an environmental assessment (EA).
EIS projects go through several stages that include draft EISs (DEIS) and final EISs (FEIS) and include comment periods for the public to review the EIS and submit comments.
