Environmental Impact Statements: Finding a FONSI

This guide provides background information on Environmental Impact Statements, and provides tools for locating statements and related documents. (Braxton)

What is a FONSI?

FONSI stands for "Finding of No Significant Impact."  Not all projects require a formal EIS, there may be only a brief Environmental Assessment with a Finding of No Significant Impact (FONSI).  See Background tab for information on various levels of environmental analysis required by NEPA.  

Where and how to Search

When searching for FONSIs in databases and library catalogs, include the phrase "finding of no significant impact" in your search.
NOTE:  Findings of No Significant Impact (FONSIs) are not included in the EPA's EIS Database.
