Senate Bill Report SB 5652: Reducing Environmental and Health Disparities in Large Port Districts

Washington Senate Bill 5652 would require large port districts — primarily the Port of Seattle, which operates Sea-Tac Airport — to develop environmental justice plans, community engagement strategies, and impact assessments aimed at reducing health and environmental disparities for residents affected by airport and port operations. For major capital projects valued at $8 million or more, or any action adding airport gates, the port would need an independent assessment from the University of Washington on cumulative health impacts to overburdened communities, along with a plan to mitigate those impacts. The bill was introduced in February 2025 and referred to the Senate Committee on Environment, Energy & Technology.
