43.21C.031 - Significant impacts.

Significant impacts.

(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) do not require environmental review or the preparation of an environmental impact statement under this chapter. In a county, city, or town planning under RCW 36.70A.040, a planned action, as provided for in subsection (2) of this section, does not require a threshold determination or the preparation of an environmental impact statement under this chapter, but is subject to environmental review and mitigation as provided in this chapter.

     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.

     (2)(a) For purposes of this section, a planned action means one or more types of project action that:

     (i) Are designated planned actions by an ordinance or resolution adopted by a county, city, or town planning under RCW 36.70A.040;

     (ii) Have had the significant impacts adequately addressed in an environmental impact statement prepared in conjunction with (A) a comprehensive plan or subarea plan adopted under chapter 36.70A RCW, or (B) a fully contained community, a master planned resort, a master planned development, or a phased project;

     (iii) Are subsequent or implementing projects for the proposals listed in (a)(ii) of this subsection;

     (iv) Are located within an urban growth area, as defined in RCW 36.70A.030;

     (v) Are not essential public facilities, as defined in RCW 36.70A.200; and

     (vi) Are consistent with a comprehensive plan adopted under chapter 36.70A RCW.

     (b) A county, city, or town shall limit planned actions to certain types of development or to specific geographical areas that are less extensive than the jurisdictional boundaries of the county, city, or town and may limit a planned action to a time period identified in the environmental impact statement or the ordinance or resolution adopted under this subsection.
