    Call To Action: Save State Funding for Port Package Updates!

    The Governor’s proposed budget cuts the $1 million in funding that was secured last year through SB 5955 for the Port Equity Fund. This fund is critical for fixing failed port packages, which were meant to insulate homes from airport noise but have deteriorated over time. Without this funding, many homeowners will be left without

    House Bill 1948 – Environmental Justice for Large Port Districts

    Washington House Bill 1948 (2025) would require large port districts — such as the Port of Seattle, which operates Sea-Tac Airport — to develop environmental justice implementation plans and community engagement plans aimed at reducing health and environmental disparities for overburdened communities affected by airport noise and other port activities. The bill mandates that these plans include specific goals, measurable metrics, and outreach strategies to ensure meaningful participation from vulnerable populations, including people with limited English proficiency. Port districts would also be required to conduct environmental justice reviews for major capital projects valued at $8 million or more, or any action that increases the number of airport gates.

    HB 1303 Bill Analysis – Increasing environmental justice by improving government decisions

    Washington State House Bill 1303 proposes strengthening environmental justice by adding new requirements to the State Environmental Policy Act (SEPA) review process, requiring environmental justice impact statements for projects in vulnerable or overburdened communities. The bill also prohibits state and local air authorities from issuing certain construction approvals for new air pollution sources in those same communities. Note: This bill focuses on statewide environmental permitting and community health protections, and does not directly address Sea-Tac Airport noise policy.

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.
