The Late-Night Noise Limitation Program is a voluntary Port of Seattle initiative that monitors aircraft noise at Sea-Tac Airport between 12 a.m. and 5 a.m., using four close-in noise monitors to track takeoffs and landings that exceed established thresholds. Airlines that violate these thresholds receive penalty scores under the Port's Fly Quiet Incentive Program, which has evaluated airline noise compliance since 2005. The program, developed in 2019 as an outcome of the Sea-Tac Stakeholder Advisory Round Table (StART), aims to encourage air carriers to schedule flights during less noise-sensitive hours or switch to quieter aircraft.

This is the meeting agenda for the Sea-Tac Stakeholder Advisory Round Table (StART) held on February 27, 2019, at Seattle-Tacoma International Airport. The meeting covered key topics including a recap of the Aviation Noise Working Group, a presentation on glide slope analysis, and an airfield taxiing noise reduction initiative. The session also included discussion of StART's 2019 priorities, with the goal of enhancing cooperation between the Port of Seattle and neighboring communities affected by airport noise.

This document is a facilitator's meeting summary from the Sea-Tac Stakeholder Advisory Round Table (StART) held on February 27, 2019, covering discussions between the Port of Seattle and neighboring communities on airport noise reduction and federal policy. Key topics included updates on a revised Runway Use Agreement, nighttime noise thresholds, the A320 aircraft whistling noise issue, and the formation of a Federal Policy Working Group involving congressional offices. The meeting also featured a presentation on glide slope analysis as a potential noise reduction measure and a discussion of StART's priorities for 2019.

The Sea-Tac Stakeholder Advisory Round Table (StART) met on February 27, 2019 to discuss ongoing airport noise reduction efforts, including updates to the Runway Use Agreement, late-night noise limits, and a recommendation to adjust Runway 34R's glideslope to reduce noise impacts on neighboring communities. The meeting also previewed the newly formed Federal Policy Working Group and introduced a concept for reducing taxiing noise by changing how arriving aircraft move to the terminal. Community members and city representatives from SeaTac, Burien, Des Moines, Normandy Park, Tukwila, and Federal Way participated in small group discussions to help set StART's priorities for 2019.

This draft 2019 priorities worksheet from the Sea-Tac Stakeholder Advisory Round Table (StART) captures input from eight community members on the issues they most wanted to address that year. Key concerns included aircraft noise (such as flight paths, nighttime operations, and noise measurement methods), air quality impacts like ultra-fine particle emissions, and relevant federal and state policy. Members also sought better data, community education opportunities, and presentations from the FAA and other experts to improve understanding of how Sea-Tac Airport affects surrounding neighborhoods.

The 2018 StART Annual Report documents the activities of the Sea-Tac Stakeholder Advisory Round Table, a group formed to improve cooperation between the Port of Seattle and communities surrounding Seattle-Tacoma International Airport. The report covers meeting objectives, the development of community priorities, and the establishment of an Aviation Noise Working Group aimed at addressing noise concerns affecting neighboring residents. It also outlines revised operating procedures and a near-term action agenda to guide noise-related efforts into 2019.

The Highline Forum held its January 23, 2019 meeting at Burien City Hall, focusing on an update of the University of Washington's Ultra-Fine Particle Study presented by researchers from the UW School of Public Health. The agenda also included a StART program update from the Port of Seattle's Noise Program Manager, selection of a 2019 Community Co-Chair, and a City of Burien host update. The forum scheduled six bimonthly meetings throughout 2019, rotating among cities near Seattle-Tacoma International Airport including Federal Way, SeaTac, Tukwila, and Des Moines.

This document summarizes a January 14, 2019 meeting of the StART Aviation Noise Working Group, which advises on noise reduction efforts around Seattle-Tacoma International Airport. Key topics included a recommendation to increase the Runway 34R glide slope angle from 2.75 to 3.1 degrees to reduce arrival noise, updates on a Late Night Noise Limitation Program, and a presentation on how reverse thrust works and its impact on ground noise. The group agreed to bring a recommendation to the Port Commission to expedite the glide slope change and proceed with an 'at-risk' design process.

This draft Letter of Agreement between the FAA and the Port of Seattle establishes a voluntary Noise Abatement Informal Runway Use Program for Seattle-Tacoma International Airport (Sea-Tac). It outlines preferred runway assignments for both South Flow and North Flow operations, with special late-night rules between midnight and 5 a.m. that reduce use of the third runway to limit noise impacts on surrounding communities. The FAA retains authority to deviate from these preferences whenever safety, weather, or operational conditions require it.
