    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.

    NEPA’s forty most asked questions

    This document outlines the forty most frequently asked questions about the National Environmental Policy Act (NEPA), covering topics such as how agencies evaluate a range of alternatives, the role of environmental impact statements (EIS), and the use of environmental assessments (EA). It provides plain-language guidance on requirements like the no-action alternative, mitigation measures, public comment periods, and records of decision. While not specific to airport noise, it serves as a foundational reference for understanding the federal environmental review process that governs major infrastructure projects such as those at Sea-Tac Airport.

    Barnes v. Federal Aviation Administration – Ninth Circuit Court Opinion

    A federal appeals court denied a challenge by Oregon residents and an aviation watchdog group against a new runway project at Hillsboro Airport near Portland, Oregon. The court found that the Federal Aviation Administration acted properly in concluding the project would have no significant environmental impact, including only a minimal effect on air traffic and air quality. This case, a follow-up to a 2011 ruling, may be relevant to discussions of how environmental reviews are conducted for airport expansion projects in the Pacific Northwest.

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.
