SEPA appeals shall be limited to review of final threshold determinations, the adequacy of final environmental impact statements, mitigation or failure to mitigate environmental impacts, and project denials. Appeals of declarations of nonsignificance, EIS adequacy, mitigation and project denial, and open record public hearings for the underlying permit(s), as described in Chapter 22.05 FMC, shall be consolidated and heard together. Declarations of significance, issued before a decision on the underlying permit(s), may be appealed and heard before the consolidated open record public hearing on the permit and other SEPA issues.
