Petition for Review of Agency Order

Three Washington cities — Burien, Des Moines, and SeaTac — have filed a legal challenge in the Ninth Circuit Court of Appeals against the Federal Aviation Administration's September 2025 decision approving near-term expansion projects at Seattle-Tacoma International Airport. The petition contests the FAA's Finding of Significant Impact/Record of Decision related to the airport's Sustainable Airport Master Plan, which the cities argue warrants judicial review. The filing, submitted November 21, 2025, was made within the 60-day statutory deadline under federal aviation law.

Notes

Petition for Review filed November 21, 2025 by the City of Burien, City of Des Moines, and City of SeaTac (Washington municipal corporations), represented by Steven M. Taber of Leech Tishman Nelson Hardiman, Inc., in the United States Court of Appeals for the Ninth Circuit under 49 U.S.C. § 46110 and FRAP Rule 15(a), seeking review of the FAA’s FONSI/ROD signed September 24, 2025 — the “Finding of Significant Impact/Record of Decision for the Sustainable Airport Master Plan Near-Term Projects at the Seattle-Tacoma International Airport” (SAMP). Respondents are the Federal Aviation Administration, Administrator Bryan Bedford, U.S. Department of Transportation, and Secretary Sean Duffy. The petition asserts Ninth Circuit jurisdiction because petitioners reside within the circuit, and argues timeliness under the 60-day filing period extended to Monday, November 24, 2025 because the 60th day fell on a Sunday.
