A petition filed in the U.S. Court of Appeals for the Ninth Circuit challenging the FAA’s Finding of Significant Impact/Record of Decision for the Sustainable Airport Master Plan Near-Term Projects at Seattle-Tacoma International Airport. The petition was filed by three Washington cities seeking review of the September 24, 2025 FAA decision.

This is a legal filing in the U.S. Court of Appeals for the D.C. Circuit in which the U.S. Environmental Protection Agency asks the court to vacate its own previously issued air quality standard, arguing that EPA lacked the statutory authority to revise the standard without completing a full review process. The case centers on National Ambient Air Quality Standards (NAAQS) under the Clean Air Act, not airport noise policy. This document does not contain information relevant to Sea-Tac Airport noise policy.

The FAA sent a letter to Washington State's Aviation Director in October 2025 reviewing how the state collects and spends aviation fuel taxes, noting that despite having an approved compliance plan, the state has still not provided actual tax collection figures after 11 years. The FAA flagged concerns about three types of taxes — aircraft fuel tax, sales and use taxes, and environmental taxes (HST and PPT) — questioning whether the environmental tax revenues are being properly directed toward aviation purposes. The agency also reviewed over $97 million in state appropriations claimed as offsets, finding more than $82 million ineligible and nearly $15 million requiring further justification before a final compliance determination can be made.
