Chapter 53.54 RCW authorizes Washington port districts operating large airports (such as Sea-Tac) to carry out programs that reduce the impact of jet aircraft noise on surrounding neighborhoods, including purchasing properties, providing soundproofing, and offering transaction assistance to affected homeowners. The law defines 'impacted areas' with specific distance limits from runways and allows properties within those boundaries to receive noise mitigation benefits. Recent 2024 updates expand the program to allow inspection, repair, or replacement of previously installed noise mitigation equipment that is no longer working as intended or has caused structural damage.

This document is the FAA's Record of Approval for Seattle-Tacoma International Airport's Noise Compatibility Program, which outlines measures to reduce aircraft noise and manage land use around the airport. It covers both new and updated measures, including voluntary rescheduling of nighttime flights, preferential runway use during nighttime hours, and a Fly Quiet Program to encourage airlines to follow noise abatement procedures. The FAA approved most measures as continuations of previously approved programs dating back to 1985, while disapproving the engine maintenance run-up regulations.

Local communities surrounding Seattle-Tacoma International Airport are demanding accountability from the Port of Seattle (POS) regarding its compliance with FAA Part 150 noise mitigation measures, some dating back to 1985. The document raises detailed questions about ten specific program elements — including voluntary flight rescheduling, engine run-up restrictions, noise abatement corridors, the Fly Quiet Program, and home sound insulation — asking for data on how consistently and effectively each measure has actually been implemented. Critics argue that despite decades of commitments, key noise reduction tools such as a Ground Run-Up Enclosure have been quietly dropped, while growing air traffic continues to harm residential neighborhoods and environmentally vulnerable populations.
