Wash. Rev. Code § 43.21C.408 – Lead agency use of nonproject environmental impact statement for electrical transmission facility.

(1) A lead agency conducting a project-level environmental review under this chapter of an electrical transmission facility with a nominal voltage of 230kV or greater must consider a nonproject environmental impact statement completed pursuant to RCW 43.21C.405 in order to identify and mitigate project-level probable significant adverse environmental impacts.
(2)
1. (a) Project-level environmental review conducted pursuant to this chapter of an electrical transmission facility with a nominal voltage of 230kV or greater must begin with the review of the applicable nonproject environmental impact statement completed pursuant to RCW 43.21C.405. The review must address any probable significant adverse environmental impacts associated with the proposal that were not analyzed in the nonproject environmental impact statements pursuant to RCW 43.21C.405. The review must identify any mitigation measures specific to the project for probable significant adverse environmental impacts.
2. (b) Lead agencies reviewing site-specific project proposals for electrical transmission facilities with a nominal voltage of 230kV or greater shall use the nonproject review described in RCW 43.21C.405 through one of the following methods and in accordance with WAC 197-11-600, as it existed as of January 1, 2023:
  1. (i) Use of the nonproject review unchanged, in accordance with RCW 43.21C.034, if the project does not cause probable significant adverse environmental impact not identified in the nonproject review;
  2. (ii) Preparation of an addendum;
  3. (iii) Incorporation by reference; or
  4. (iv) Preparation of a supplemental environmental impact statement.
(3) Proposals for electrical transmission facilities with a nominal voltage of 230kV or greater following the recommendations developed in the nonproject environmental review completed pursuant to RCW 43.21C.405 are considered to have mitigated the probable significant adverse project-specific environmental impacts under this chapter for which recommendations were specifically developed unless the project-specific environmental review identifies project-level probable significant adverse environmental impacts not addressed in the nonproject environmental review.
