Code of Federal Regulations Title 33. Navigation and Navigable Waters § 33.230.11 Finding of No Significant Impact (FONSI)

A FONSI shall be prepared for a proposed action, not categorically excluded, for which an EIS will not be prepared. The FONSI will be a brief summary document as noted in 40 CFR 1508.13. In the case of feasibility, continuing authority, or special planning reports and certain planning/engineering reports, the draft FONSI and EA should be included within the draft report and circulated for a minimum 30–day review to concerned agencies, organizations and the interested public (40 CFR 1501.4(e)(2)). In the case of operation and maintenance activities involving the discharge of dredged or fill material requiring a public notice, the notice will indicate the availability of the EA/FONSI. For all other Corps project actions a notice of availability of the FONSI will be sent to concerned agencies, organizations and the interested public (40 CFR 1501.4(e)(1)).
