## Text

(1) An environmental impact statement (the detailed statement required by RCW 43.21C.030 (2)(c)) shall be prepared on proposals for legislation and other major actions having a probable significant, adverse environmental impact. The environmental impact statement may be combined with the recommendation or report on the proposal or issued as a separate document. The substantive decisions or recommendations shall be clearly identifiable in the combined document. Actions categorically exempt under RCW 43.21C.110 (1)(a) and 43.21C.450 do not require environmental review or the preparation of an environmental impact statement under this chapter. (2) An environmental impact statement is required to analyze only those probable adverse environmental impacts which are significant. Beneficial environmental impacts may be discussed. The responsible official shall consult with agencies and the public to identify such impacts and limit the scope of an environmental impact statement. The subjects listed in RCW 43.21C.030 (2)(c) need not be treated as separate sections of an environmental impact statement. Discussions of significant short-term and long-term environmental impacts, significant irrevocable commitments of natural resources, significant alternatives including mitigation measures, and significant environmental impacts which cannot be mitigated should be consolidated or included, as applicable, in those sections of an environmental impact statement where the responsible official decides they logically belong.
