    The Effect of Occupational Exposures to Aircraft Ultrafine Particles on Acute Cardiorespiratory Health, and Control Using Personal Protective Equipment

    A University of Washington thesis by Mariah Dittmore investigates whether short-term exposure to ultrafine particles from aircraft engines causes measurable cardiorespiratory harm at concentrations found in surrounding communities, and whether personal protective equipment can reduce that harm. The research builds on a 2018 Los Angeles study that linked walking near aircraft pollution to elevated blood inflammation markers, while noting that roadway traffic posed its own distinct respiratory risks. The findings are relevant to policy discussions around Seattle-Tacoma International Airport and the health of workers and residents exposed to aircraft emissions.

    Waterfront Community with Aviation Infrastructure

    Image shows a waterfront community with residential buildings, beach area, and forested hills in the background. Several people are visible on the beach, and the scene appears to be in the Pacific Northwest region near what could be an airport-impacted community.

  • Sea-Tac Airport BHS Baggage Conveyor Belt System with Motor Drive Units

    Interior view of a blue-and-yellow baggage conveyor belt system with multiple motor drive units and control panels mounted along curved belt sections. Equipment labels visible include alphanumeric unit identifiers (e.g., 'SS22-14', 'TM51-0x', unit '13'), consistent with an airport baggage handling installation.

  • Boeing 737 MAX in Green Primer Livery Taxiing at Boeing Field

    A Boeing 737 MAX aircraft in green primer livery, bearing line number 7396, taxis at Boeing Field (King County International Airport) in front of the Boeing manufacturing facility. The aircraft appears to be destined for Jet Airways based on the partial tail livery visible, photographed during what appears to be a pre-delivery flight operation.

    Tableau Operations Carrier vs. Taxi

    A line chart showing scheduled aircraft operations over time for three categories: Air Carrier (aircraft with over 70 seats), Air Taxi (aircraft with less than 70 seats), and All Other. Air Carrier operations peak near 450K before declining sharply at the right end of the chart, while Air Taxi operations rise and then fall dramatically to near zero.

    Airbus A320 “Whistle”: ONCC Technical Committee Meeting, April 14, 2020

    Airbus A320 family aircraft (A318, A319, A320, A321) manufactured before 2014 produce a distinctive high-pitched whistling noise during descent, caused by airflow passing through Fuel Over Pressure Protector (FOPP) cavities located on each wing. The noise fades once the landing gear is deployed. A small device called a vortex generator, installed just in front of each vent opening, has been identified as an effective fix, reducing noise levels by up to 4 decibels during the approach phase.

    Twin-Engine Widebody Jet on Final Approach at Sea-Tac Airport

    A twin-engine widebody commercial jet, viewed from below and behind, is captured on final approach with all landing gear fully deployed. The aircraft features a red nose cone and red tail markings consistent with a major carrier livery, possibly American Airlines or a similar operator, but no registration or text is clearly legible.

    Sea-Tac Airport Aerial View with Runways, Concourses, and Puget Sound

    Aerial photograph of Seattle-Tacoma International Airport (SEA/KSEA) in SeaTac, Washington, showing the main terminal complex, concourses with aircraft at gates, parallel runways, and surrounding urban areas. Puget Sound and the Seattle skyline are visible in the background, consistent with the airport's location between Seattle and Tacoma.

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.
