Washington State House Bill 1505 aims to promote the alternative jet fuel industry by establishing tax breaks for businesses that produce or sell alternative jet fuel, updating the state's Clean Fuels Program to better support aviation fuels, and directing Washington State University to convene a workgroup to study and make recommendations on alternative jet fuel policy. The bill also expands the Department of Commerce's Statewide Office of Renewable Fuels to include alternative jet fuels as a focus area. While the bill primarily addresses fuel economics and climate goals rather than airport noise directly, it is relevant to Sea-Tac Airport operations as it could influence the types of fuels used by aircraft flying in and out of the region.

This Washington State University Cooperative Extension factsheet explains the risks of heavy metals such as lead, cadmium, and arsenic in garden soils, with a focus on the greater Seattle-Tacoma region. It identifies locations most likely to have contamination, including sites near old painted buildings, heavily traveled roads, and areas affected by the former Tacoma smelter. The factsheet offers practical gardening tips to reduce exposure, such as growing fruiting crops, adding organic matter, liming soil, and washing produce thoroughly.

A 2001 EPA air quality study measured toxic airborne pollutants across six Seattle-area neighborhoods, including a site near Seattle-Tacoma International Airport that was notably impacted by emissions from nearby freeways and congested streets. Researchers collected air samples over the course of a year to track levels of harmful compounds including volatile organic chemicals (VOCs), carbonyls, and metals. The findings were intended to help assess community health risks and guide the development of a long-term national air toxics monitoring network.

This March 2000 report, prepared by Washington State health and environmental agencies, examines whether jet engine exhaust emissions from Seattle-Tacoma International Airport can be monitored or modeled using wind and takeoff data. It reviews previous air quality studies, outlines health and environmental justice concerns for nearby communities, and recommends a structured air quality monitoring study with specific methods, data analysis approaches, and estimated costs. The report was developed in consultation with community representatives, the EPA, and local universities.
