(a) The District Engineer will prepare a finding of no significant impact if the District Engineer determines, based on the environmental assessment, not to prepare an environmental impact statement because the proposed activity will not have significant effects. The finding of no significant impact will:

(1) Be included in the environmental assessment;

(2) Document the reasons why the District Engineer has determined that the selected alternative will not have a significant effect on the quality of the human environment;

(3) If the District Engineer finds no significant effects based on mitigation, the mitigated finding of no significant impact will state any mitigation requirements enforceable by the agency or voluntary mitigation commitments that will be undertaken by the applicant to avoid significant effects;

(4) Identify any other documents related to the finding of no significant impact; and

(5) State that the District Engineer will not prepare an environmental impact statement, concluding the NEPA process for that permit application, request for permission, or mitigation instrument.

(b) The District Engineer may publish notification of the environmental assessment and finding of no significant impact on a public website.
