Ninth Circuit Court of Appeals unpublished memorandum decision in City of Burien v. Daniel K. Elwell and Federal Aviation Administration, No. 18-71705, filed November 27, 2019. The court partially agreed with Burien that the FAA acted arbitrarily and capriciously under NEPA (42 U.S.C. §§ 4321 et seq.) by approving the ‘Burien 250 Turn’ procedure —

In October 2019, Congressman Adam Smith (WA-9th District) wrote to the Government Accountability Office requesting that its study on FAA aircraft noise management be expanded beyond major metropolitan 'metroplexes' to also include Single Site airports, such as those affected by NextGen flight procedure changes near smaller cities. The letter asks the GAO to examine how the FAA measures, discloses, and mitigates noise impacts at these airports, whether its current noise standards adequately protect communities, and how effectively it engages the public when implementing new flight routes. The request was driven by significant community concern over increased noise resulting from NextGen-related flight path changes at Single Site airports.

FAA Order JO 7110.126A, effective September 28, 2019, updates the rules air traffic controllers use to maintain safe distances between aircraft based on wake turbulence — the invisible air disturbances generated by planes in flight. The order introduces a nine-category system that groups aircraft by size and wake behavior, replacing older weight-only classifications, and reduces required separation distances in cases where science has shown greater spacing is unnecessary, such as when one heavy aircraft follows another of lower wake intensity. Facilities like Sea-Tac must obtain FAA authorization, train all personnel, and update their systems before applying these revised standards.

FAA Order JO 7110.126A, effective September 28, 2019, updates the rules air traffic controllers use to maintain safe distances between aircraft to avoid wake turbulence. The order introduces a nine-category system for classifying aircraft by their wake turbulence characteristics, replacing older weight-based separation standards with more precise, data-driven minimums that can reduce unnecessary spacing between certain aircraft pairs. These updated standards are designed to improve traffic flow and runway efficiency at busy airports across the national airspace system.

FAA Order 5090.5, effective September 3, 2019, establishes guidelines for managing the National Plan of Integrated Airport Systems (NPIAS) and the Airports Capital Improvement Plan (ACIP), which together identify airports important to national air transportation and prioritize federal funding for airport development projects. The order serves as a financial planning tool for systematically assigning Airport Improvement Program (AIP) funds to qualifying airports across the country. Note that this document addresses broad national airport capital planning policy and does not contain specific provisions related to Sea-Tac Airport noise mitigation or local noise policy.
