This EPA report, prepared by David Mudarri PhD in 2018, reviews the state of science on indoor environmental quality and outlines research, policy, and program options for improving it. The synthesis paper was developed to help the EPA establish research goals, objectives, and priorities across a wide range of indoor environmental topics and time frames. It is intended solely for internal EPA use due to the inclusion of copyrighted material from broad-based review articles.

A 2019 U.S. Department of Transportation Inspector General report found that the FAA's Metroplex program—designed to modernize flight routes using satellite-based navigation in busy metropolitan areas—fell significantly short of its promised benefits, delivering only $31.1 million in annual savings compared to the $61.6 million minimum originally projected. The program also faced delays of up to four years, driven largely by community concerns about aircraft noise, which is directly relevant to ongoing noise issues around airports like Sea-Tac. Key obstacles such as unclear pilot-controller terminology and a slow procedure amendment process remained unresolved at the time of the report.

The Aviation Impacted Communities Act establishes a structured process to help neighborhoods affected by aircraft noise, starting with the FAA identifying eligible communities and ending with grants for noise mitigation. A community qualifies as 'aviation impacted' if it is located within 1 mile of any point where a commercial or cargo jet route passes at or below 3,000 feet above ground level. Once designated, communities can form boards, conduct studies, and develop action plans to address aviation-related impacts near airports like Sea-Tac.

This legislative summary outlines a proposed bill aimed at protecting communities affected by airport noise and aviation emissions. It establishes a formal designation for 'aviation-impacted communities' located within one mile of low-flying commercial or cargo jet routes, creates local community boards to engage with the FAA and airport operators, and requires the FAA to develop action plans and provide mitigation funding — such as sound insulation and noise barriers — for affected residences, schools, hospitals, and nursing homes.

A 2019 Port of Seattle internal audit of the Noise Insulation Program — which has invested over $400 million since 1985 to reduce aircraft noise in homes and schools near Sea-Tac Airport — found two key problems: a contractor called Burton Construction overbilled the Port by an average markup of 51% above subcontractor costs, and the Highline School District failed to consistently meet federal grant requirements for disadvantaged business enterprises and Buy American standards. The audit covered January 2013 through March 2019 and assessed compliance with FAA federal grant rules.
