This document argues that the FAA and Sea-Tac Airport failed to properly account for combined aircraft noise from both Sea-Tac and Boeing Field when approving the Greener Skies/NextGen flight program, leaving hundreds of Beacon Hill homes without sound insulation assistance they may have been entitled to. A 2002 King County International Airport study had already identified that noise levels in parts of Beacon Hill exceeded the 65 dB DNL federal threshold when both airports' noise was measured together, yet no mitigation was provided. The document also highlights that no public outreach was conducted in the Beacon Hill neighborhood—a majority-Asian, multilingual community—before the new flight paths were implemented.

Former King County International Airport (BFI) Noise Officer Sharyn Parker's prepared notes for a GAO interview outline significant concerns about FAA regulatory failures and Sea-Tac Airport's inadequate noise mitigation practices in the Seattle region. Parker argues that the FAA has consistently failed to require Sea-Tac to update noise exposure maps, enforce timely sound mitigation programs, or conduct meaningful public outreach — particularly for minority communities disproportionately affected by flight path changes like the Greener Skies/RNP initiative. The notes also highlight contradictions between Sea-Tac's deliberately low flight-operation projections in its Part 150 noise studies and the far higher growth figures used in its capital development plans.

The 'Greener Skies' program, approved by the FAA in late 2012 and promoted by the FAA and Port of Seattle, promised to dramatically reduce aircraft noise near Sea-Tac Airport by routing more than half of all arrivals over Elliott Bay, far from residential areas. Critics argue the program was fundamentally flawed and never delivered on its promises, as air traffic controllers rarely use the Elliott Bay routes due to the need to merge east- and west-side arrival streams. FAA and industry's own data are cited as evidence that the program amounted to an environmental fraud, with concentrated flight paths continuing to impact west-side communities while east-side routes were never given equivalent precision procedures.
