The lead agency shall work with the cooperating agencies and shall obtain comments as required in part 1503 of this chaptersubchapter. To the fullest extent practicable, the draft statement must meet the requirements established for final statements in section 102(2)(C) of NEPA as interpreted and in the regulations in this subchapter. If the agency determines that a draft statement is so inadequate as to preclude meaningful analysis, the agency shall prepare and publish a supplemental draft of the appropriate portion. At appropriate points in the draft statement, the agency shall discuss all major points of view on the environmental impacts effects of the alternatives, including the proposed action.

(c) Final environmental impact statements. Final environmental impact statements shall address consider and respond to comments as required in part 1503 of this chaptersubchapter.

(ii) There are significant substantial new circumstances or information relevant to environmental concerns and bearing on the proposed action or its impactsabout the significance of adverse effects that bear on the analysis.

(2) May also prepare supplements when the agency determines that the purposes of the Act will be furthered by doing so.

(3) Shall prepare, publish, and file a supplement to a an environmental impact statement (exclusive of scoping (§ 15011502.9 4 of this chaptersubchapter)) as a draft and final environmental impact statement, as is appropriate to the stage of the environmental impact statement involved, unless the Council approves alternative procedures arrangements (§ 1506.12 11 of this chaptersubchapter).

(

the

its finding consistent with its agency NEPA procedures (§ 1507.3 of this
