In March 2026, Washington State aviation and transportation officials exchanged emails revealing that the state faces approximately $210 million in aviation fuel tax liability after an FAA audit found it had been improperly diverting aviation fuel tax revenues to non-compliant uses. Even if all disputed expenditures—totaling about $32.6 million—were proven allowable, Washington would still be found in non-compliance, prompting the state's Aviation Director to recommend a proactive resolution strategy with the FAA. The correspondence also references federal law allowing state aviation fuel taxes to fund 'state aviation programs,' with ongoing debate about whether uses such as Sustainable Aviation Fuel development could qualify as compliant under that definition.

This document is an email chain from March 2026 between Washington State Department of Transportation (WSDOT), the Governor's Office, and the FAA regarding Washington State's compliance with federal aviation fuel tax requirements. WSDOT missed a February 18, 2026 deadline to provide information requested by the FAA, and the FAA subsequently issued a demand warning that compliance and enforcement actions would follow if the information was not received within 10 days. WSDOT officials indicated they do not have the ability to provide the requested information and sought guidance from the Governor's Office and the Office of Financial Management.

These emails document a 2025–2026 federal compliance matter in which the FAA reviewed Washington State's aviation fuel tax practices to determine whether they met federal revenue-use requirements. After Washington missed a February 18, 2026 response deadline, the FAA notified state officials at the Department of Revenue and WSDOT, prompting coordination between multiple state agencies. While related to aviation finance rather than airport noise policy directly, the correspondence reflects ongoing federal oversight of Washington State's aviation funding obligations.

Washington Senate Bill 5898 proposes redirecting a portion of the state's hazardous substance tax on aircraft fuel to fund noise relief for communities near airports. Specifically, 25 percent of those tax proceeds would go into a new "state aircraft noise mitigation account," with the remaining 75 percent continuing to flow to the aeronautics account as before. The Department of Commerce would administer a grant program using these funds to support noise mitigation strategies in communities located within designated aviation impact areas, with the law taking effect July 1, 2027.
