This technical report, prepared by Landrum & Brown for the Port of Seattle in January 2024, covers hazardous materials, solid waste, and pollution prevention as part of the Sustainable Airport Master Plan's near-term projects at Seattle-Tacoma International Airport. It includes assessments of contaminated fuel farm sites, regulated building materials such as asbestos and lead in airport structures, and environmental investigation reports for fueling sites. Supporting attachments document findings from agencies like Washington State Ecology and surveys of specific airport buildings managed by tenants including United Airlines and Swissport.

This 2023 report from the Washington State Department of Ecology focuses on improving air quality in overburdened communities that are highly impacted by air pollution across Washington State. It outlines regional office contacts, accessibility services, and language assistance resources available to affected residents. Note: This document does not specifically address Sea-Tac Airport noise policy and may not be directly relevant to airport noise concerns.

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.

This document outlines the Washington State Department of Ecology's 2023-25 Biennium Enacted Operating Budget, totaling approximately $862.6 million with 2,136.5 full-time employees. It details funding changes across priority areas including climate impact reduction, toxic threat prevention, and water protection, with notable investments in Clean Energy Permitting, Climate Commitment Act implementation, and water quality programs. The budget reflects a net increase of roughly $157.8 million over the carryforward base budget through a combination of maintenance level adjustments and new policy-level initiatives.

Washington State's Department of Ecology has identified 16 overburdened communities across the state that are highly impacted by criteria air pollution, collectively representing over 1.2 million residents. Using air quality data and environmental justice tools, the agency is working under the Climate Commitment Act to reduce six key pollutants — including particle pollution, ozone, and nitrogen dioxide — in areas ranging from South Seattle and South King County to rural communities like Mattawa and the Lower Yakima Valley. Next steps include expanding air monitoring, engaging affected communities, and working with Tribal governments to address pollution impacts over multiple years.

This March 2023 technical support document from the Washington State Department of Ecology's Air Quality Program outlines methods for identifying communities that are disproportionately burdened by air pollution across Washington State. It provides regional office contact information and maps showing the four Ecology regions covering all 39 Washington counties. Note: this document focuses on statewide air quality and environmental justice topics and does not contain information specific to Sea-Tac Airport noise policy.
