    Petition for Review FAA NEPA FONSI ROD email chain

    City of SeaTac officials exchanged emails in November 2025 regarding a Petition for Review filed to appeal the FAA's NEPA Finding of No Significant Impact (FONSI) and Record of Decision, coordinated under an Interlocal Agreement (ILA) with the cities of Burien and Des Moines. A council member raised concern about the petition listing 'Attorneys for Vashon Island Fair Skies' rather than the three cities, to which Director Evan Maxim clarified that outside legal counsel Mr. Taber also represents other parties including Vashon Island in a related SAMP appeal, and that the reference was likely included by mistake. SeaTac is identified as the primary party in the event of any conflict of interest among the represented parties.

    Interlocal agreement for coordinated SAMP review and legal services

    The City of Des Moines and neighboring cities have entered into an Interlocal Agreement (ILA) to coordinate their review of and response to the SeaTac Airport Master Plan (SAMP) environmental review process, covering both federal (NEPA) and state (SEPA) requirements. Originally signed in 2018 and updated in 2024, the agreement establishes how participating cities share costs, manage contracts, and jointly hire environmental and legal consultants—including attorneys who can support a legal challenge to the SAMP's environmental conclusions. The latest version, managed by the City of SeaTac and expected to run through December 31, 2028, excludes Normandy Park but otherwise continues the multi-city partnership focused on protecting community interests during the airport planning process.

Issues

As the source for federal transportation grants, the Puget Sound Regional Council was charged with developing a system to meet the growing need for commercial aviation. When the search for a second airport failed, they authorized the Port of Seattle to build the Third Runway, with a mandate to develop a noise abatement and mitigation program. In their effort to stop the Third Runway, the ACC argued over every detail of the Port's efforts--including property buyouts and sound insulation. The dispute was meant to be settled by a three member Expert Arbitration Panel. This is their final report. It finds 2-1, that the Port's program was insufficient in several respects. Despite that, funding for the Third Runway was approved by the PSRC, and the 'Port Package' program, proceeded largely unchanged. Expert Arbitration Panel's final decision finding that the Port of Seattle had not shown sufficient reduction in real on-the-ground noise impacts to satisfy noise reduction conditions required for approval of a third runway at Sea-Tac International Airport. The majority decision concluded the Port's noise abatement programs were insufficient despite being impressive in scope.
