The Aviation Noise and Emissions Mitigation Act, introduced by Rep. Adam Smith (WA-09), aims to help communities near airports — including those around Sea-Tac — deal with the health risks posed by aviation noise and air pollution. The bill would create two EPA grant programs: one funding research and neighborhood-level monitoring of noise and emissions, and another supporting mitigation efforts such as home soundproofing, public health programs, and healthcare services for affected residents. The legislation responds to studies linking airport emissions to increased risks of cancer, heart disease, and asthma, as well as findings that aircraft noise negatively affects children's learning.

Washington Senate Bill 5652 requires large port districts, such as the Port of Seattle, to develop and adopt environmental justice implementation plans and community engagement plans by January 1, 2026. These plans must outline how the port will reduce environmental and health disparities in overburdened communities, particularly those affected by aircraft noise, and ensure meaningful participation from vulnerable populations in port decision-making. The bill also mandates compliance with federal civil rights laws and requires the use of screening tools to assess the health and demographic impacts of major port actions valued at $8 million or more.

The Green Burien Partnership 2025 Snapshot highlights the City of Burien's urban forestry and environmental stewardship efforts, including planting 607 trees on city property, distributing over 800 free trees to the community, and protecting 516 trees during development. The program, funded entirely through external grants and partnerships with organizations like King Conservation District, also engaged youth and volunteers through 12 community events and a paid youth stewardship program at Hilltop Park. Burien was recognized in 2025 as an Evergreen Community with 25 years as Tree City USA and 8 years of Growth Award.

The City of Tukwila submitted formal comments on December 13, 2024, objecting to SeaTac Airport's Sustainable Airport Master Plan Draft Environmental Assessment (SAMP Draft EA), arguing that the study area is too narrow, covering only 3,692 acres, and fails to account for broader impacts on surrounding communities including increased traffic, air quality degradation, and noise under flight paths. The city contends that proposed mitigation measures are inadequate and that the assessment ignores equity and social justice concerns affecting the low-income, diverse communities near the airport. Tukwila is calling for a full Environmental Impact Statement with an expanded General Study Area that includes the entire city and broader South King County region.

This document presents formal public comments opposing an FAA Environmental Assessment for expansion projects at Seattle-Tacoma International Airport. The author argues that the stated justification for expansion is misleading, contending that airport growth would not automatically occur without new gates and terminals since FAA safety rules already cap the number of aircraft operations. Additional concerns raised include disproportionate health burdens on nearby communities, unreliable air pollution modeling, inadequate environmental justice analysis, and failure to properly assess cumulative public health and climate impacts.

Four cities near Seattle-Tacoma International Airport — Burien, Normandy Park, SeaTac, and Des Moines — submitted formal comments in December 2024 objecting to the airport's Sustainable Airport Master Plan Environmental Assessment. The cities warn that planned growth will increase annual flight operations by nearly 20% by 2032, expanding the noise impact zone and exposing an estimated 22,000 residents to significant aircraft noise, up from about 14,000 in 2022. They call on the Port of Seattle to extend public review periods, improve its sound insulation program, and take proactive steps to protect the low-income and minority communities most burdened by airport noise.

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.

In May 2024, the Council on Environmental Quality published major updates to the rules governing how federal agencies must review environmental impacts of projects, affecting everything from public participation to project timelines. The changes place new emphasis on environmental justice, requiring agencies to meaningfully engage communities facing disproportionate environmental burdens, and remove previous rules that limited who could challenge agency decisions in court. While some updates are designed to speed up the review process, others may add new requirements for agencies and project sponsors seeking federal permits or funding.

This document is an Environmental Justice Protocol prepared by Landrum & Brown, Incorporated for the Federal Aviation Administration and the Port of Seattle in June 2024. It addresses socioeconomics, environmental justice, and children's health considerations related to Seattle-Tacoma International Airport. The protocol provides a framework for evaluating how airport-related impacts may affect minority, low-income, and other vulnerable populations in surrounding communities.
