TagEnvironmental Impact Statement(140)

In a March 10, 2020 letter to Burien Mayor Jimmy Matta, FAA Regional Administrator David C. Suomi explained that an Environmental Assessment (EA) — not a full Environmental Impact Statement — is the appropriate level of review for Sea-Tac Airport's Near Term Projects (NTP), which are designed to meet projected demand through 2027. The EA will evaluate all resource categories and cumulative impacts from past, present, and foreseeable projects on and near the airport. The FAA noted that preparing an EA does not rule out a future Environmental Impact Statement if significant impacts are identified.

In March 2020, the Burien City Council wrote to the FAA requesting a comprehensive Environmental Impact Statement (EIS) that fully accounts for the cumulative noise and air quality impacts of Sea-Tac Airport's rapid growth, which saw operations increase by nearly 30% between 2014 and 2018. The letter argues that multiple airport expansion projects — including new terminal gates and altered flight paths — were each approved without significant environmental review, but together have caused substantial harm to surrounding communities. The council also cites a 2019 Ninth Circuit Court ruling that found the FAA failed to properly assess cumulative impacts, and demands the agency conduct a thorough analysis using a pre-expansion baseline of 2013.

The Burien Airport Committee met in January and February 2020 to address concerns related to Seattle-Tacoma International Airport, including efforts to push the FAA to conduct a full Environmental Impact Statement (EIS) rather than a lesser Environmental Assessment (EA) for the Sustainable Airport Master Plan. The committee also discussed re-engagement with the StART (Sea-Tac Airport Roundtable) process, involving six cities in dialogue with the Port of Seattle, and planned a joint visit to Washington, D.C. in March 2020 to advocate for community interests on airport noise and expansion issues.

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.

In summer 2019, Burien City Manager Brian Wilson coordinated with partner cities (Normandy Park, SeaTac, and Des Moines) and federal relations consultants at Lockridge Grindal Nauen to review a Port of Seattle presentation on the Seattle-Tacoma International Airport Master Plan (SAMP) Near-Term Projects Environmental Review, which had been delivered to the Burien City Council on June 17, 2019. The emails show Wilson requesting that consultant Emily Tranter analyze the presentation given by Port of Seattle Director of Aviation, Environment, and Sustainability Arlyn Purcell, in order to help the cities determine their next steps in responding to the airport's environmental review process. Wilson followed up with additional comments and questions on the resulting review, reflecting ongoing community concern about the potential noise and environmental impacts of planned airport expansion projects.

In May 2019, Burien City Manager Brian Wilson updated the Burien Airport Committee on the cities' joint effort to respond to the Port of Seattle's Sustainable Airport Master Plan (SAMP), which outlines airport expansion through 2027. The cities of Burien, Des Moines, Normandy Park, and SeaTac formed an Interlocal Agreement (ILA) and hired the Washington DC firm Lockridge Grindal Nauen to help review and comment on the SAMP's environmental impact process. Key community concerns raised in the accompanying September 2018 scoping letter include aircraft noise, air quality, traffic congestion, and the disproportionate burden placed on neighborhoods closest to Seattle-Tacoma International Airport.

ATAC Corporation, an aviation analysis firm based in Santa Clara, CA, plays a major role in developing the FAA's Aviation Environmental Design Tool (AEDT), which models aircraft noise and emissions at both local and global scales. The document also includes a letter from the FAA's Seattle Airports District Office congratulating an airport on the approval of its Part 150 Noise Compatibility Program, a formal plan aimed at reducing or eliminating incompatible land uses around the airport. The FAA notes that approval of the program does not guarantee federal funding, and encourages the airport to periodically review and update the plan as conditions change.

The Burien Airport Committee (BAC) met on October 16, 2018 to discuss aviation noise issues related to Sea-Tac Airport, including a review of Federal Way's Quiet and Healthy Skies Task Force recommendations and public comments on the Sea-Tac Airport Sustainable Airport Master Plan (SAMP) Environmental Impact Statement. The committee also received updates on the City of Burien's legal petition challenging the FAA's approval of a 250-degree flight heading over Burien, which was described as still in early litigation stages. Additional topics included FAA funding for noise mitigation staff, a Washington State Department of Commerce airport impacts study, and a regional aviation baseline study by the Puget Sound Regional Council.
