[Code of Federal Regulations] [Title 40, Volume 31] [Revised as of January 1, 2008] From the U.S. Government Printing Office via GPO Access [CITE: 40CFR1502.23] [Page 1123] TITLE 40--PROTECTION OF ENVIRONMENT CHAPTER V--COUNCIL ON ENVIRONMENTAL QUALITY PART 1502_ENVIRONMENTAL IMPACT STATEMENT--Table of Contents Sec. 1502.23 Cost-benefit analysis. If a cost-benefit analysis relevant to the choice among environmentally different alternatives is being considered for the proposed action, it shall be incorporated by reference or appended to the statement as an aid in evaluating the environmental consequences. To assess the adequacy of compliance with section 102(2)(B) of the Act the statement shall, when a cost-benefit analysis is prepared, discuss the relationship between that analysis and any analyses of unquantified environmental impacts, values, and amenities. For purposes of complying with the Act, the weighing of the merits and drawbacks of the various alternatives need not be displayed in a monetary cost-benefit analysis and should not be when there are important qualitative considerations. In any event, an environmental impact statement should at least indicate those considerations, including factors not related to environmental quality, which are likely to be relevant and important to a decision.
