    Seattle-Tacoma International Airport Part 150 noise compatibility study final: Chapter one – inventory

    ★
    This document is Chapter One of the Seattle-Tacoma International Airport (Sea-Tac) Part 150 Noise Compatibility Study, finalized in October 2013. It provides an overview of the airport's size, ownership by the Port of Seattle, and its role as the Pacific Northwest's primary commercial hub, while explaining the federal regulations (14 CFR Part 150) that guide airport noise compatibility planning. The study was undertaken to update a 2002 noise plan, accounting for major changes such as the opening of a third parallel runway in 2008, with the goal of reducing noise impacts on surrounding communities.

    Sustainable Airport Master Plan (SAMP) Near-Term Projects (NTP) environmental review briefing and request for additional funds

    The Port of Seattle requested $3.4 million in additional funding to complete environmental review studies required under federal (NEPA) and state (SEPA) law for planned near-term expansion projects at Sea-Tac Airport. The cost increase was driven by a two-year planning delay, expanded public engagement in multiple languages, additional technical analyses including aircraft noise, air quality, and environmental justice studies, and a decision to produce two separate review documents instead of one combined report. The contract with aviation environmental consulting firm Landrum & Brown brings the total project cost to $6.4 million.

    Seattle-Tacoma International Airport (Sea-Tac) Part 150 Study

    The Port of Seattle completed an updated Part 150 Noise and Land Use Compatibility Study for Seattle-Tacoma International Airport (Sea-Tac), which was approved by the Port of Seattle Commission in October 2013 and subsequently received a Record of Approval from the Federal Aviation Administration (FAA). The study identifies noise incompatibilities in communities surrounding Sea-Tac and recommends measures to reduce aircraft noise, building on earlier programs such as a 'fly-quiet' initiative and sound insulation efforts. Sea-Tac is recognized as having one of the most comprehensive airport noise reduction programs in the nation, and this updated study is intended to further minimize the impact of aircraft noise on neighboring communities.

    Seattle-Tacoma International Airport (Sea-Tac) Part 150 study

    The Seattle-Tacoma International Airport (Sea-Tac) Part 150 Noise and Land Use Compatibility Study, approved by the Port of Seattle Commission in October 2013 and later by the FAA, aims to identify and reduce aircraft noise impacts on surrounding communities. The study developed noise exposure maps for 2013 and projected 2018 conditions, evaluated air traffic control procedures, and considered land use controls to limit noise-sensitive development in high-noise areas. Sea-Tac is recognized for having one of the most comprehensive airport noise reduction programs in the nation, with measures including a 'fly-quiet' program and sound insulation assistance for affected residents.

Issues

Sea-Tac Airport is currently undergoing the largest and longest expansion in its history, collectively known as the Sustainable Airport Master Plan (SAMP). Some of it you can already hear, but you’re probably not aware of what it all means. Here’s what you need to know.

As the source for federal transportation grants, the Puget Sound Regional Council was charged with developing a system to meet the growing need for commercial aviation. When the search for a second airport failed, they authorized the Port of Seattle to build the Third Runway, with a mandate to develop a noise abatement and mitigation program. In their effort to stop the Third Runway, the ACC argued over every detail of the Port's efforts--including property buyouts and sound insulation. The dispute was meant to be settled by a three member Expert Arbitration Panel. This is their final report. It finds 2-1, that the Port's program was insufficient in several respects. Despite that, funding for the Third Runway was approved by the PSRC, and the 'Port Package' program, proceeded largely unchanged. Expert Arbitration Panel's final decision finding that the Port of Seattle had not shown sufficient reduction in real on-the-ground noise impacts to satisfy noise reduction conditions required for approval of a third runway at Sea-Tac International Airport. The majority decision concluded the Port's noise abatement programs were insufficient despite being impressive in scope.
