§ 1503.3 Specificity of comments and information.
(a) To promote informed decision making, comments on an environmental impact statement or on a proposed action shall be as specific as possible, may address either the adequacy of the statement or the merits of the alternatives discussed or both, and shall provide as much detail as necessary to meaningfully participate and fully inform the agency of the commenter's position. Comments should explain why the issues raised are important to the consideration of potential environmental impacts and alternatives to the proposed action, as well as economic and employment impacts, and other impacts affecting the quality of the human environment. Comments should reference the corresponding section or page number of the draft environmental impact statement, propose specific changes to those parts of the statement, where possible, and include or describe the data sources and methodologies supporting the proposed changes.
