    EPA Region 10 Letter to Port Of Seattle: Review of FAA Draft Environmental Assessment for Sea-Tac Airport SAMP Near Term Projects

    The U.S. EPA reviewed the Federal Aviation Administration's draft environmental assessment for Sea-Tac Airport's near-term expansion projects, which include a new second terminal, cargo facilities, and other infrastructure planned through 2032. The EPA raised concerns about disproportionate health and environmental impacts on surrounding communities, noting that air quality indicators such as diesel particulate matter and nitrogen dioxide already exceed the 80th state percentile in the project area. The agency recommends that the final assessment more thoroughly address environmental justice, air quality, climate change, and wetlands impacts on these overburdened neighborhoods.

    Email Exchange: Normandy Park Mayor Eric Zimmerman on SAMP Frustrations and StART Strategy

    In a November 2024 email exchange, Normandy Park Mayor Eric Zimmerman acknowledges frustration with the Sea-Tac Airport Master Plan (SAMP) process, explaining that the Port of Seattle Commission holds the real power over airport growth but that pro-growth cities like Seattle and Bellevue dominate that political landscape. He cautions against taking an activist stance toward the Port, warning that doing so could jeopardize the city's participation in the StART engagement process and cost Normandy Park hard-won mitigation benefits, such as an overnight runway use agreement that shifted late-night landings away from the third runway. The email was prompted by a journalist named Stuart Jenner, who reported writing a story about SAMP meetings held on November 13 and 14, 2024.

    Figure 4-1 from a Seattle-Tacoma International Airport planning document shows historical and forecast total aircraft operations (in thousands) from 2011 to 2038, broken down by passenger airlines, all-cargo airlines, and other operations. The forecast, sourced from LeighFisher (June 2022, updated August 2023), projects growth from 429,000 operations in 2023 to 567,000 by 2038.

  • Table 4-2: Summary of Potential Environmental Impacts – Socioeconomic, Environmental Justice, and Children’s Health

    This table excerpt from an environmental review document compares three alternatives (No Action, Proposed Action, and Hybrid Terminal Option) for impacts on socioeconomic conditions, environmental justice populations, and children's health and safety risks at Seattle-Tacoma International Airport (SEA). Under the Proposed Action, two businesses (Doug Fox Lot and PACCAR Aviation) and one intersection (24th Avenue South from S. 150th Street) would be closed, with no significant or disproportionate adverse impacts found after mitigation.

Issues

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.

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.
