About Wautoma Solar Project

EFSEC received the application for site certification (ASC) for the Wautoma project on May 20, 2022. An informational public meeting and land use hearing were held on August 8, 2022. On November 6, 2022, EFSEC issued an order finding the project inconsistent with land use regulations. EFSEC issued a mitigated determination of nonsignificance (MDNS) on May 20, 2024. A revised MDNS was issued on June 14, 2024. An adjudicative proceeding to determine if the Council should recommend preemption of local land use provisions was held on September 25, 2024. On November 22, 2024, EFSEC sent their recommendation to Governor Inslee, including a recommendation of preemption local land use laws. The governor approved the project on January 9, 2025.
