The Burien Airport Committee (BAC) met on May 15, 2018 to discuss air quality, FAA updates, and strategies for addressing Seattle-Tacoma International Airport's impact on the Burien community. Key priorities included updating noise contour maps, gathering environmental justice data, reviewing air pollution studies, and identifying economic benefits for Burien from its proximity to the airport. The committee also reviewed draft minutes from its April 17, 2018 meeting, where members were assigned tasks such as drafting a resolution on airport noise and emission concerns.

This document presents a community challenge to the FAA's environmental review (CATEX) of new flight routes near Seattle-Tacoma International Airport, arguing that the FAA's own noise analyses show significant noise increases in the surrounding General Study Area that exceed the agency's own significance thresholds. The authors contend that the FAA could not rely on the outdated 2013-2018 Port of Seattle Part 150 noise study, and that the FAA's independent analyses revealed noise level jumps ranging from 5.2% to nearly 60% across various decibel contours. The document concludes that the FAA's declaration of 'no noise impacts' is implausible given data showing that portions of previously quiet neighborhoods now experience non-compatible land use noise levels above 65 dB DNL.

This 2018 technical memorandum outlines a Sustainability Planning and Management Strategy for Seattle-Tacoma International Airport, developed by Leigh Fisher and Synergy Consultants for the Port of Seattle. It establishes sustainability goals, objectives, and metrics across financial, environmental, and social focus areas, drawing on FAA guidance and Port of Seattle commitments. The document also addresses climate change risks to airport facilities and provides a framework for integrating sustainability into near-term airport development decisions.

This document bundle relates to a 2018 media inquiry from KING 5 Television to the City of Burien regarding an FAA flight path decision affecting the Seattle-Tacoma (Sea-Tac) Airport area, along with an FAA Air Traffic Initial Environmental Review from May 2016. The environmental review describes a proposed Letter of Agreement between Sea-Tac's Air Traffic Control Tower and the Seattle Terminal Radar Approach Control facility to standardize turboprop departure headings to 250 degrees during north flow operations, routing smaller aircraft westward to improve safety and reduce ground delays. The change was intended to de-conflict slower turboprops from faster jet traffic and Boeing Field operations, though it raised noise concerns for communities such as Burien located under the newly defined flight paths.

The Burien Airport Committee (BAC) met on April 17, 2018 to discuss the city's response to Sea-Tac Airport-related concerns, including noise contour maps, air pollution health impacts, and environmental justice issues. The committee reviewed potential priorities such as updating FAA noise contour maps, inventorying air pollution studies, and engaging Port of Seattle commissioners on community concerns. Draft minutes from the March 20, 2018 meeting were also included, documenting the committee's brainstorming of initiatives to better understand airport impacts and advocate for the Burien community.

In April 2018, the FAA issued a Categorical Exclusion allowing Seattle-Tacoma International Airport's control tower (SEA ATCT) to automatically direct southbound turboprop aircraft to turn westward to a 250-degree heading within one nautical mile of the runway end, rather than waiting for the Seattle TRACON radar facility to issue the turn after takeoff. This procedural change, active between 6 am and 10 pm during north-flow operations, was designed to improve safety and efficiency by reducing delays in aircraft transitioning to their filed flight routes. The FAA determined the action would not significantly increase noise over sensitive areas and therefore required no further environmental review beyond this Categorical Exclusion.

This April 2018 Federal Aviation Administration document describes a proposed procedural change at Seattle-Tacoma International Airport to automatically direct southbound turboprop aircraft to a 250-degree westerly heading during north-flow operations between 6 am and 10 pm, rather than requiring air traffic controllers to manually coordinate each turn. The nighttime hours of 10 pm to 6 am were excluded from the automatic turn procedure in response to community concerns from the City of Burien and other residents about flight noise over sensitive areas. The document evaluates this preferred alternative alongside other options, including changes to heading angles and missed approach procedures, which were ultimately eliminated due to safety and airspace separation requirements.

FAA categorical exclusion document for updating a Letter of Agreement between Seattle-Tacoma International Airport’s Air Traffic Control Tower and Seattle Terminal Radar Approach Control to automate a 250° westerly turn for southbound turboprops during north-flow operations. The automated turn would be suspended between 10 pm and 6 am in response to comments from the City
