TagRunway Use Agreement(8)

In September 2019, the Port of Seattle announced two new programs to reduce late-night aircraft noise at Seattle-Tacoma International Airport. A revised Runway Use Agreement with the FAA took effect on September 4, limiting use of the Third Runway (16R/34L) between midnight and 5 a.m., while a new voluntary Late Night Noise Limitation Program encourages airlines to schedule flights during less noise-sensitive hours or switch to quieter aircraft during the same period. Both initiatives stemmed from recommendations by the Sea-Tac Airport Stakeholder Advisory Round Table (StART).

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.

The StART Aviation Noise Working Group held its first meeting on August 16, 2018, bringing together community stakeholders, airlines, the FAA, and Port of Seattle representatives to discuss strategies for reducing aircraft noise around Sea-Tac Airport. The group reviewed four potential near-term approaches—including a Runway Use Agreement, a Nighttime Voluntary Curfew, Glide Slope and Optimized Profile Descent Analysis, and an Airfield Noise/Reverse Thrust Assessment—all of which were deemed worthy of further exploration. The group agreed to meet monthly and outlined next steps, including gathering night-operations data and drafting a formal work program to guide future action.

This document outlines the Runway Use Agreement between the FAA and the Port of Seattle at Seattle-Tacoma International Airport (Sea-Tac), effective December 6, 2010. It establishes preferred runway assignments for arrivals and departures under various weather and traffic conditions, while making clear that safety and air traffic management always take priority. The agreement does not change existing FAA practices but aims to provide consistency and transparency for the public regarding how runways are used.
