Directing the completion of a study of certain environmental impacts, including ultrafine particulate emissions, associated with aircraft traffic in areas impacted by airport operations.

Would require the School of Public Health to help with an assessment of air quality surrounding SeaTac Airport. At the moment, the bill does not have any funding earmarked for the UW to complete the assessment.

1ST SUBSTITUTE COMPARED TO ORIGINAL:
The substitute bill adds new requirements to the Department of Commerce's (Commerce) study of ultrafine particulate matter emissions, including requiring an analysis of gaps and uncertainties in ultrafine particulate matter information. The scope of the study is also expanded to include the air emissions of barium, aluminum, radioactive thorium, cadmium, chromium, and ethylene dibromide. Commerce must coordinate with local governments in areas near the airport to share the results of the air quality study, and solicit public feedback. The scope of the study must encompass areas within 10 miles of the airport that feature an existing air monitoring station or that are in the airport's direct flightpath.

The second phase of study and associated 2021 reporting requirements are eliminated. Instead, Commerce must recommend, in conjunction with the submission of the report to the Legislature by December 1, 2019, whether sufficient information is available to validate proceeding with a second phase of the study. New criteria are included in the second phase of a study, should a second phase be carried out, including an analysis of public health impact mitigation options, and an evaluation of the role of the Federal Aviation Administration in any mitigation options.
