18 C.F.R. § 1318.302

(a) TVA will prepare a finding of no significant impact if TVA determines, based on the EA, not to prepare an EIS because the proposed action will not have significant effects. The finding of no significant impact will:

(1) Include the EA or incorporate it by reference;

(2) Document TVA's determination that the proposed action will not have a significant effect on the quality of the human environment;

(3) State the authority for any mitigation that TVA has adopted and any applicable monitoring or enforcement provisions. If TVA finds no significant effects based on mitigation, the mitigated finding of no significant impact will state any mitigation requirements enforceable by TVA or voluntary mitigation commitments that will be undertaken to avoid significant effects;

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

(5) State that an EIS will not be prepared, concluding the NEPA process for the action.

(b) TVA will publish a FONSI as part of an EA or as a separate document.
