These are the minutes from a November 18, 1998 joint meeting of the Citizens' Advisory Committee and Technical Advisory Committee for the Sea-Tac Airport Part 150 Noise Study, held at Sea-Tac International Airport. The meeting covered the presentation of a preliminary noise contour map, updates on subcommittee activities related to airport operations and noise data analysis, and announcements about upcoming public events. Key discussion topics included run-ups, adherence to flight tracks, Fly Quiet programs, and how noise data would be measured and presented to the public.

This document contains materials from the Seattle-Tacoma International Airport FAR Part 150 Noise Study, including an agenda for a Citizens Advisory Committee meeting held on July 22, 1998, at the airport's Main Terminal Building. The meeting covered topics such as a presentation of Working Paper One on inventory, preliminary noise monitoring results, and an open house discussion. A tentative schedule for follow-up meetings through December 1998 was also included, covering sub-committee sessions and additional CAC/TAC public meetings.

This Port of Seattle glossary defines key acoustic and air traffic control terms used in airport noise policy discussions. It explains measurements like decibels (dB), A-weighted decibels (dBA), and the Day-Night Noise Level (DNL), which is a 24-hour average used to map noise exposure around Sea-Tac Airport. It also covers Federal Aviation Regulations (Parts 36, 91, and 161) that govern aircraft noise standards, phase-out schedules for older noisy aircraft, and the process for airports to adopt new noise rules.

This May 1998 document from the Barnard Dunkelberg & Company Team presents a FAR Part 150 Study Update for Seattle-Tacoma International Airport, covering the history of federal aviation noise policy. It traces key regulatory milestones including the FAA Aviation Noise Abatement Policy of 1976, the Aviation Safety and Noise Abatement Act of 1979, and the Airport Noise and Capacity Act of 1990. The document explains what FAR Part 150 is, what it means for airport operators and surrounding communities, and how voluntary land-use compatibility studies evolved into formal regulatory requirements over time.

This 1987 Draft Environmental Impact Statement from the Puget Sound Council of Governments evaluates alternatives for expanding the regional airport system in the Puget Sound area through the year 2020. The study found that all alternatives would generate significant impacts to both natural and human environments, including noise and land-use concerns, with the key distinction being whether those impacts would be concentrated at existing airport sites or spread across new locations. No single alternative was found to be clearly superior, and the report called for extensive mitigation measures and further site-specific analysis to guide final decision-making.

A January 1984 Port of Seattle memorandum notifies the Technical Working Committee of an upcoming meeting on January 25 to review noise remedy programs for Jackson (Sea-Tac) International Airport, including land acquisition, purchase assurance, and sound insulation proposals. Attached is a draft chapter evaluating on-airport and off-airport noise abatement measures against ten criteria, such as airspace compatibility and aircraft safety. The document outlines which measures were recommended for implementation following an initial screening process described in an earlier chapter.

A letter from Bill Holstine to Sea/Tac noise and air pollution impacted community residents announcing a meeting to discuss the completed Noise Update Study results and potential legal action against the Port of Seattle. The meeting was scheduled for January 26, 1983, and would include an attorney to discuss legal processes and an M.D. to

These are the meeting minutes from a March 23, 1982 Policy Advisory Committee session at Sea-Tac International Airport, focused on updating the Sea-Tac/Communities Plan Noise Remedy Program. The committee discussed how to engage affected residents between South 128th and South 135th Streets through direct mailings and community outreach, debated whether to address noise impact areas individually or as a whole, and reviewed the status of ongoing housing acquisitions, with the Port having already spent $28–$29 million on housing acquisition and relocation. Key concerns included funding limitations, construction in potential acquisition zones, hardship cases for vulnerable residents, and the timeline for completing the program.

Port of Seattle memorandum announcing the second Airspace Study Advisory Committee meeting scheduled for February 24, 1982. The agenda includes aviation demand forecasts for Sea-Tac and Boeing Field, discussion of airfield and airspace capacities, and aircraft delays.

A December 29, 1981 letter from Port of Seattle Chairman Oris W. Dunham, Jr. notifies Policy Advisory Committee members that their upcoming meeting has been rescheduled from January 13 to January 14, 1982 at 2:00 p.m. in Sea-Tac's auditorium due to a scheduling conflict. The primary focus of the meeting remains the Noise Exposure Update, with additional agenda items also planned for discussion. Members were advised that the final agenda would be mailed during the first week of 1982.
