(a) If an action is subject to NEPA and unless TVA finds that the proposed action is excluded from having to prepare an EA or EIS pursuant to a categorical exclusion as determined following the procedures in subpart C of this part, or by another provision of law, TVA will prepare an EA with respect to a proposed agency action that does not have a reasonably foreseeable significant effect on the quality of the human environment, or if the significance of such effect is unknown. TVA is mindful of Congress' direction that EAs are to be “concise.” NEPA sec. 106(b)(2); 42 U.S.C. 4336(b)(2).

(b) An EA will concisely communicate information and analyses about issues that are potentially significant and a reasonable range of alternatives.
