Seattle Airport aircraft emissions, noise mitigation, and additional regional airport capacity

20 May 2024

The Port of Seattle and communities near Seattle-Tacoma International Airport (SEA) have successfully secured multiple priorities in the recently passed FAA Reauthorization bill, thanks to a collaborative effort with the state’s congressional delegation. These provisions include measures to address aircraft emissions, noise mitigation, and additional regional airport capacity. Notable policies in the bill are:

  • A study of ultrafine particulates from aircraft engines.
  • A one-year deadline for FAA action on potential noise policy changes and the creation of a stakeholder advisory panel.
  • A regional airport capacity report.
  • Renewal of an environmental mitigation pilot program for reducing aircraft noise and emissions.

The Port's Stakeholder Advisory Round Table (StART), comprising local officials, airline representatives, and community members, played a crucial role in advocating for these policies. Their efforts included a significant delegation trip to Washington, D.C., to push for these changes.

Additionally, the bill provides the Port with more flexibility regarding the future of North SeaTac Park, allowing it to potentially preserve the park permanently despite previous federal funding restrictions.

The legislation has passed both the House and the Senate and awaits the President's signature. The Port of Seattle, through StART, continues to work on noise reduction programs and sound insulation efforts for the surrounding communities, having invested nearly $300 million in sound reduction improvements to date.
