How to Search for Environmental Impact Statements

Printer-friendly versionSend by email

The National Environmental Policy Act of 1969 requires that federal agencies prepare detailed analyses of any of their actions that significantly affect the quality of the environment. Environmental impact statements (EIS's) are the result of this requirement. EIS's have been produced, since 1969, on virtually every type of activity, from oil and gas development to scientific research in Antarctica, and from protection of wildlife habitat to construction of light rail lines.

One of the world's largest collections of environmental impact statements is available for your use in the Transportation Library (University Library, 5th Floor, North Tower). Nearly all of the EIS's issued by federal agencies since 1969 are held, usually in draft as well as final form. Related documents such as environmental assessments, findings of no significant impact, records of decisions, supplementary reports, and maps are collected. A small collection of environmental impact statements issued by individual states and by foreign governments is also maintained. Since 2012, the issuing agencies have provided EIS's in digital format.

EIS's can be searched in the Library's discovery tool, NUtran, using the Environmental Impact Statement tab.

The print EIS collection is arranged on our shelves alphabetically by sponsoring federal agency, then alphabetically by state, then numerically by the EPA number. Through 1999 the first two digits of the EPA number indicate the year the report was issued; those  issued from 2000 on, the full year is used.  Multi-state EIS's are shelved by the sponsoring agency abbreviation and the EPA number only.

This is an example of a search for an EIS sponsored by the Federal Aviation Administration (FAA) in the state of Arkansas (AR):

EIS's are also listed on the EPA Office of Federal Activity's web site <http://www.epa.gov/compliance/nepa/index.html> by date of distribution.
