The Port of Seattle requested $3.4 million in additional funding to complete environmental review studies required under federal (NEPA) and state (SEPA) law for planned near-term expansion projects at Sea-Tac Airport. The cost increase was driven by a two-year planning delay, expanded public engagement in multiple languages, additional technical analyses including aircraft noise, air quality, and environmental justice studies, and a decision to produce two separate review documents instead of one combined report. The contract with aviation environmental consulting firm Landrum & Brown brings the total project cost to $6.4 million.

The Burien Airport Committee met on January 21, 2020 to discuss key aviation issues affecting the city, including advocating for a full Environmental Impact Statement (EIS) from the FAA rather than a less comprehensive Environmental Assessment (EA) related to Sea-Tac Airport's growth. The agenda also covered topics such as the Port's fuel dumping policy, updates on community re-engagement efforts through StART, and a planned trip to Washington, DC to address airplane noise concerns. Draft minutes from the December 2019 meeting reflect ongoing debates about air quality, health, and safety impacts stemming from airport expansion projects like the International and North Terminals.

Ninth Circuit Court of Appeals unpublished memorandum decision in City of Burien v. Daniel K. Elwell and Federal Aviation Administration, No. 18-71705, filed November 27, 2019.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

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.

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.

These two letters from 2019 address community concerns about noise and environmental impacts from Seattle-Tacoma International Airport (Sea-Tac). The EPA's Region 10 Regional Administrator responds to a Burien resident, explaining the agency's limited role in the NEPA review process and directing her to engage with the FAA regarding the Sustainable Airport Master Plan (SAMP) Environmental Assessment. Separately, the Port of Seattle's Executive Director responds to Burien's mayor, acknowledging community concerns about aircraft noise and emphasizing the Port's commitment to collaboration through forums such as the Sea-Tac Stakeholder Advisory Round Table (StART).

A consulting team addresses two community concerns about Seattle-Tacoma International Airport: the lack of a direct NEPA environmental review covering noise impact growth between 2012 and 2018, and questions about how the airport's third runway is being used. The document explains that while current NEPA and Part 150 processes will capture existing noise conditions, they will not specifically compare 2012 versus 2018 impacts, and that federally funded runways like the third runway must be made available whenever air traffic control deems it necessary. The consultants propose reviewing historical Part 150 studies, past NEPA documents, and third-runway records to assess noise impacts on surrounding communities, while also supporting clients in engaging the Port, FAA, and airlines through the StART committee and other channels.

A community analysis of the SR 509 highway extension near Sea-Tac Airport warns that the project will significantly increase truck and vehicle traffic through Burien, worsening air quality and noise for nearby residents. Critics argue that neither WSDOT nor the FAA has conducted adequate site-specific or cumulative impact studies, despite actual emissions being nearly three times higher than 1996 projections and the area already being identified as an environmental justice community. The document calls for a comprehensive cumulative analysis of combined highway traffic and airport operations to properly assess public health risks.
