TagTechnical Advisory Committee(8)

The Washington State Department of Commerce's Technical Advisory Committee (TAC) reviewed 72 recommendations from a study on Sea-Tac Airport's impacts on neighboring cities, ultimately prioritizing 13 key next steps. These priorities span public health, air quality, noise and vibration, mobility, and environmental concerns, including expanding late-night noise limits, improving air quality monitoring, and developing alternative noise metrics beyond standard day-night average (DNL) contours. The TAC also recommended revising the report's language around the Port of Seattle's airport expansion plans to reflect that the proposal was still under FAA review at the time of publication.

In a November 2019 letter to the Washington State Department of Commerce, SeaTac Mayor Erin Sitterley raised concerns about the management of the Seattle-Tacoma International Airport Study, which SeaTac is funding to the tune of $150,000. The city questioned whether consultant Stantec had strayed from the study's original technical scope, flagged potentially wasteful spending on travel from Dallas, and expressed doubt that the study would be completed on time and thoroughly by the June 2020 deadline. The city demanded a full budget accounting and requested that public input be limited until after a draft report was completed and reviewed by the Technical Advisory Committee.

This 1971 technical report, prepared by Theodore J. Schultz of Bolt Beranek and Newman Inc. for the U.S. Department of Housing and Urban Development (HUD), provides the scientific and technical background for noise abatement measures in HUD's housing programs. It supports HUD's guidelines for assessing noise exposure at residential sites, offering detailed evaluation procedures for determining acceptable noise levels near housing developments. The report was originally published in September 1970 and later revised to align with updated HUD noise exposure assessment guidelines.
