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.

This chapter explains the health risks associated with air pollutants commonly found near airports, including both criteria pollutants like carbon monoxide, lead, and particulate matter, and hazardous air pollutants like volatile organic compounds and polycyclic aromatic hydrocarbons. It describes how these pollutants can cause a range of health effects, from mild irritation to serious conditions such as respiratory disease, cardiovascular illness, and cancer. Smaller particulate matter is highlighted as a particular concern near airports, as it can penetrate deeper into the lungs and occurs at higher concentrations near aircraft operations.

This document is a federal funding opportunity from the U.S. Environmental Protection Agency (EPA) offering grants through the Environmental and Climate Justice Community Change Grants Program, with applications accepted on a rolling basis until November 21, 2024. It outlines eligibility requirements, funding tracks, and application procedures for communities seeking support for environmental and climate justice projects. Note: This document does not appear to be directly related to Sea-Tac Airport noise policy.

The Washington State Attorney General's Office 2024 Environmental Justice Report details efforts to protect communities—particularly low-income and communities of color—from disproportionate environmental harms through the Healthy Environment for All (HEAL) Act. The report covers actions such as lawsuits, community outreach, and policy letters aimed at reducing pollution and toxic exposures across Washington State. Note: This document does not address Sea-Tac Airport noise policy and may not be relevant to that specific topic.

This document is a modification to a U.S. EPA funding opportunity notice for the Environmental and Climate Justice Community Change Grants Program, issued December 21, 2023. It updates application rules, eligibility requirements, and evaluation criteria for community organizations seeking environmental and climate justice grants. Note: this document does not appear to be directly related to Sea-Tac Airport noise policy.

Washington State's Department of Ecology has operated the Seattle-Beacon Hill Air Monitoring Station since 1979, tracking pollutants such as ozone, nitrogen dioxide, fine particles, and air toxics to ensure compliance with national air quality standards. Over four decades of data show significant air quality improvements, including a 60% decline in nitrogen dioxide and a 40% reduction in fine particle concentrations, largely due to stricter emissions regulations. The station also supports ongoing research and community efforts to address air pollution disparities in overburdened neighborhoods of South Seattle.
