The Burien Airport Committee met on December 17, 2019 to discuss ongoing concerns related to Sea-Tac Airport, including the city's legal findings against the FAA, the status of a University of Washington ultrafine particles study, and safety issues raised by Alaska Airlines and Horizon Air. The committee also reviewed progress on the Sea-Tac Stakeholder Advisory Round Table (StART) and a Washington State Department of Commerce study, while planning priorities for 2020. Draft minutes from the November 18, 2019 meeting were included, detailing earlier discussions on noise reduction, environmental impacts, and a potential meeting with the EPA.

The Ninth Circuit Court of Appeals partly sided with the City of Burien in its challenge against the FAA's approval of a flight procedure that routes low-flying turboprop planes westward over Burien after takeoff from Seattle-Tacoma Airport. The court found that the FAA acted arbitrarily and capriciously by failing to consider all reasonably foreseeable future actions at Sea-Tac when evaluating whether the procedure's cumulative environmental and noise impacts required a full environmental review under the National Environmental Policy Act (NEPA). The FAA had attempted to exempt the procedure from such review by classifying it as a 'categorical exclusion,' but the court determined that the agency's cumulative impacts analysis was incomplete.

The City of Burien challenged the FAA's approval of a flight procedure that automatically routes southbound turboprop planes westward after takeoff from Seattle-Tacoma Airport, concentrating low-flying aircraft noise over the city. The Ninth Circuit Court of Appeals found that the FAA acted improperly by failing to consider all reasonably foreseeable future actions at Sea-Tac when it assessed whether the procedure's cumulative environmental and noise impacts warranted a full environmental review. The court agreed with Burien that the FAA's use of a categorical exclusion to bypass that review was arbitrary and capricious under the National Environmental Policy Act.

Ninth Circuit Court of Appeals unpublished memorandum decision in City of Burien v. Daniel K. Elwell and Federal Aviation Administration, No. 18-71705, filed November 27, 2019.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 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 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.
