The Federal Aviation Administration (FAA) released a Final Environmental Assessment (EA) in September 2025 for near-term construction and development projects at Seattle-Tacoma International Airport, prepared on behalf of the Port of Seattle. The Final EA was updated from an earlier Draft EA to reflect public and agency comments, correct errors, and remove sections on climate change, environmental justice, and cumulative impacts following changes to federal executive orders, regulations, and a 2025 Supreme Court ruling. These regulatory shifts meant the FAA was no longer required to analyze how the proposed projects might affect vulnerable communities or contribute to broader environmental trends.
