    AMENDED CERTIFIED INDEX TO THE ADMINISTRATIVE RECORD

    The Federal Aviation Administration filed an amended certified index to the administrative record in two Ninth Circuit cases challenging the FAA's September 24, 2025, Finding of No Significant Impact/Record of Decision for near-term construction projects at Seattle-Tacoma International Airport. The cases were brought by Vashon Island Fair Skies and the City of Burien, among others, who are contesting the agency's environmental review of the airport expansion plans. The full administrative record was made available to petitioners electronically on May 8, 2026.

    Citing national security needs, the FCCand FAA take steps on UAS regulation

    The FCC and FAA have taken steps to regulate drone operations near critical infrastructure, with the FAA proposing a new petition-based system allowing facility owners to apply for drone flight restrictions over their sites. The proposed rule would create two levels of restricted airspace and applies to facilities across 16 critical infrastructure sectors, such as energy, transportation, and healthcare. State laws, such as Florida's Unmanned Aircraft Systems Act, may impose additional independent restrictions on drone operations beyond the federal framework.

    Sustainable Airport Master Plan near-term projects environmental review – SEPA draft environmental impact statement and public comment period

    The Port of Seattle released a Draft Environmental Impact Statement (DEIS) under the State Environmental Policy Act (SEPA) for the Sustainable Airport Master Plan Near-Term Projects at Sea-Tac Airport, finding that surface transportation is the only category with significant impacts requiring mitigation. The review examined sixteen environmental categories including noise, air quality, and community impacts, with a 60-day public comment period running from May 22 to July 21, 2026, including in-person meetings in SeaTac, Burien, Des Moines, and Federal Way. A final SEPA determination is expected by the end of 2026.

    What’s heating up for spring – federal permitting policy update

    This May 2026 ESA policy briefing provides an update on federal permitting policy, noting that all three branches of government — legislative, executive, and judicial — are actively shaping permitting decisions. A key highlight is that Trump's second term has seen a dramatically higher number of first-year executive orders than any previous administration in recent history, signaling an aggressive pace of executive action on regulatory and permitting matters. While the document focuses broadly on federal permitting trends, its content is relevant to infrastructure and environmental review processes that can affect airport-related noise and land-use decisions.

Sea-Tac Airport is currently undergoing the largest and longest expansion in its history, collectively known as the Sustainable Airport Master Plan (SAMP). Some of it you can already hear, but you’re probably not aware of what it all means. Here’s what you need to know.

Read This!

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.
