The FAA issued a Negative Determination in July 2024, concluding that planned Near-Term Projects at Seattle-Tacoma International Airport (SEA) are not likely to cause coastal effects under the Coastal Zone Management Act. The projects include taxiway extensions, blast pad expansions, and relocation of navigational equipment across four airfield areas, with construction set to begin in 2026 over a six-year period. Because all FAA actions are confined to upland areas within the airport property, no significant impacts to Washington State's coastal zone resources were identified.

In May 2024, the Council on Environmental Quality published major updates to the rules governing how federal agencies must review environmental impacts of projects, affecting everything from public participation to project timelines. The changes place new emphasis on environmental justice, requiring agencies to meaningfully engage communities facing disproportionate environmental burdens, and remove previous rules that limited who could challenge agency decisions in court. While some updates are designed to speed up the review process, others may add new requirements for agencies and project sponsors seeking federal permits or funding.

This technical report, prepared by Landrum & Brown for the Port of Seattle in June 2024, outlines the purpose and need for near-term construction and improvement projects identified in Sea-Tac Airport's Sustainable Airport Master Plan. It is part of a broader set of supporting documents that also covers alternatives analysis, terminal needs assessment, and air cargo facility requirements. The report provides the foundational justification for proposed airport development decisions and infrastructure changes.

This document is an Environmental Justice Protocol prepared by Landrum & Brown, Incorporated for the Federal Aviation Administration and the Port of Seattle in June 2024. It addresses socioeconomics, environmental justice, and children's health considerations related to Seattle-Tacoma International Airport. The protocol provides a framework for evaluating how airport-related impacts may affect minority, low-income, and other vulnerable populations in surrounding communities.

This technical report, prepared by Landrum & Brown for the Port of Seattle in June 2024, outlines the purpose and need for near-term capital projects identified in Sea-Tac Airport's Sustainable Airport Master Plan. It is part of a broader set of supporting documents that also covers alternatives analysis, terminal needs assessment, and air cargo facility requirements. The report provides the foundational justification for proposed airport improvements and infrastructure expansions at Seattle-Tacoma International Airport.

This document is a review by ABCx2 of a Port of Seattle presentation to the city of Burien regarding the Sea-Tac Airport Master Plan (SAMP) Environmental Impact Statement. It raises concerns about the Port's decision to limit its environmental review of airport impacts to 2018 rather than 2012, questions whether significant construction growth and flight increases during that period were properly analyzed under federal (NEPA) and state (SEPA) environmental law, and challenges the Port's characterization of the FAR Part 150 noise abatement process as purely voluntary. The document also examines potential consequences if the Port fails to meet noise mitigation commitments tied to federal funding.

A legal and regulatory analysis arguing that the FAA must conduct a broader cumulative environmental impact review of Seattle-Tacoma International Airport expansion, following a 9th Circuit Court ruling that remanded the 'Burien Turn' flight path back to the FAA. The document contends that multiple airport expansion projects—including the addition of 14 new gates and the extension of Highway 509—were each approved individually under categorical exclusions (CATEXs) without properly accounting for their combined effects on noise, air quality, and environmental justice communities. The author argues that under NEPA regulations, the FAA is required to analyze these past, present, and future actions together to determine whether their collective impact is significant.
