The Port of Seattle completed an updated Part 150 Noise and Land Use Compatibility Study for Seattle-Tacoma International Airport (Sea-Tac), which was approved by the Port of Seattle Commission in October 2013 and subsequently received a Record of Approval from the Federal Aviation Administration (FAA). The study identifies noise incompatibilities in communities surrounding Sea-Tac and recommends measures to reduce aircraft noise, building on earlier programs such as a 'fly-quiet' initiative and sound insulation efforts. Sea-Tac is recognized as having one of the most comprehensive airport noise reduction programs in the nation, and this updated study is intended to further minimize the impact of aircraft noise on neighboring communities.

The Port of Seattle responded in October 2019 to detailed questions from the City of Burien about aircraft noise management at Sea-Tac Airport, addressing concerns about noise studies, abatement procedures, sound insulation programs, and community engagement. The Port defended its 2014 Part 150 noise study as covering all three runways and argued that improved aircraft technology has actually reduced the noise-impacted area since the previous study. It also outlined ongoing mitigation efforts, including a Late-Night Noise Limitation Program, over $300 million spent on sound insulation for thousands of homes, and the upcoming Sustainable Airport Master Plan environmental review, which will reassess noise impacts across all runways.

The Port of Seattle responds to questions from the City of Burien about aircraft noise studies, noise abatement procedures, and community mitigation programs at Seattle-Tacoma International Airport. The Port clarifies that its 2014 Part 150 noise study covered all three runways and actually showed a smaller noise-impacted area due to quieter aircraft technology, and that the upcoming Sustainable Airport Master Plan environmental review will further assess noise impacts. The document also addresses concerns about the pace of sound insulation programs, the transparency of the StART community advisory process, and the legal and regulatory constraints that limit the Port's ability to mandate certain noise reduction measures.

The Sea-Tac Stakeholder Advisory Round Table (StART) met on August 28, 2019 to discuss airport noise reduction efforts, federal policy priorities, and an overview of Part 150 noise studies. Key updates included progress on a Revised Runway Use Agreement, the launch of a Late Night Noise Limitation Program, and a new noise complaint system. The meeting also addressed the temporary suspension of three neighboring cities from StART, with airport leadership pledging improved communication and good-faith efforts to re-engage those communities.

In August 2019, the City of Burien sent a formal letter to the Port of Seattle's Executive Director and Commissioners raising nine pointed questions about Sea-Tac Airport's noise policies and community health impacts. The city challenged the Port's failure to conduct updated noise studies across all runways since 2002, slow implementation of sound insulation programs, and lack of transparency in the StART community committee process. Burien concluded by calling for an honest public dialogue about whether continued airport growth is sustainable given the environmental and quality-of-life consequences for neighboring residents.

In August 2019, the Burien City Council sent a formal letter to the Port of Seattle's Executive Director and Commissioners raising nine pointed questions about Sea-Tac Airport's noise management failures, including the lack of updated noise studies since 2002, slow implementation of sound insulation for affected homes, unaddressed air quality concerns, and the exclusion of meaningful community input. The letter argues that the Port has prioritized airport expansion and profits over the health and quality of life of surrounding residents for more than 20 years. The Council calls for an honest, open dialogue about how much airport growth is truly sustainable given its ongoing environmental and community impacts.

In August 2019, the City of Burien sent a draft letter to the Port of Seattle raising eight pointed questions about Seattle-Tacoma International Airport's handling of aircraft noise, air quality, and community impact. The letter challenges the Port's failure to conduct comprehensive noise studies since 2002, its slow implementation of sound insulation programs, and its prioritization of airport expansion planning over legally recommended noise mitigation measures. Burien officials conclude that the Port has not treated compatibility with surrounding communities as a genuine priority, citing decades of unaddressed recommendations dating back to a 1996 Expert Arbitration Panel report.

The Highline Forum held a public meeting on July 31, 2019, at Highline College in Des Moines, Washington, focusing on the FAA Part 150 Aviation Noise Program and the South King County Fund, both related to managing aircraft noise impacts around Seattle-Tacoma International Airport. Port of Seattle staff presented updates on community engagement, environmental funding, and noise mitigation efforts, with additional time for public comment and discussion of emerging issues. The forum also announced two upcoming 2019 meetings scheduled for September 25 in Tukwila and November 20 in Des Moines.
