2002-06-03Record of approval: Federal Aviation Regulation Part 150 noise compatibility program, Seattle-Tacoma International Airport, Seattle, Washington
This document is the FAR Part 150 Noise Compatibility Program Study Update for Seattle-Tacoma International Airport (Sea-Tac), approved by the FAA in June 2002. It outlines a series of measures aimed at reducing aircraft noise, including establishing a public oversight committee, exploring noise barriers and ground run-up enclosures, and encouraging the voluntary phase-out of older, louder Stage 2 jet aircraft. The FAA approved some measures outright, while others—such as revised maintenance run-up regulations and the voluntary aircraft phase-out—were disapproved pending submission of additional supporting information. -

1998-12-28Airport Improvement Program: FAA complying with requirement for local involvement in noise mitigation projects
A 1998 U.S. General Accounting Office report examined whether the FAA was required to enforce a policy mandating written declarations of local support before awarding noise mitigation grants to Seattle-Tacoma International Airport. The report found that while FAA policy called for such written declarations from affected cities and counties, neither federal law nor FAA regulations legally required them. FAA officials maintained they still met the broader statutory requirement of ensuring noise mitigation projects were consistent with local plans. -
