Academic journal article published in Environmental Health Perspectives (April 2020, Vol. 128(4)) by Wing, Larson, Hudda, Boonyarattaphan, Fruin, and Ritz examining whether ultrafine particles (UFPs) from jet aircraft emissions at Los Angeles International Airport (LAX) are associated with increased preterm birth (PTB) rates. Study used California Department of Public Health birth records (2008–2016) for 174,186 mothers within 15 km of LAX, with UFP exposure estimated via a validated AERMOD geospatial dispersion model. Results show OR of 1.14 (95% CI: 1.08, 1.20) for PTB in the highest versus lowest UFP quartile (IQR = 9,200 particles/cc), adjusting for NO2 traffic-related air pollution, airport noise (CNEL), maternal race/ethnicity, education, nativity, and neighborhood socioeconomic status; authors include Neelakshi Hudda (Tufts University), Timothy Larson (University of Washington), and Beate Ritz (UCLA).

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.
