• Study the implications of air traffic at Sea-Tac • Assess the concentrations of ultrafine particulate matter (UFP) in areas surrounding and directly impacted by air traffic • Distinguish between and compare concentrations of aircraft- related and other sources of UFP • Coordinate with local governments, and share results and solicit feedback from community Community Engagement Funding for the MOV-UP study was provided to the University of Washington by a proviso in the state budget. Study Advisory Group *3 meetings to date Ongoing communication with community *6 meetings to date e.g., Highline Forum, Federal Way City Council, Seattle/King Board of Health, Airport Impacts Meeting Media Coverage Important characteristic of Ultrafine Particles • They have a large amount of surface area, relative to their size. • They are small enough to enter the bloodstream, cross the placenta, and cross the blood-brain barrier. • Because they are small, they have very little mass. • Typically, they are measured differently than PM2.5, which includes larger particles, and therefore has appreciable mass that can be weighed. Ultrafine Particles (UFPs) Ultrafine Particles unregulated but potentially important Health Effects more uncertain compared to PM2.5 ,but a growing body of evidence Diesel Engines emit ultrafine particles resulting in elevated levels near major roadways (within 200 meters downwind) Jet aircraft directly emit “ultra” ultrafine particles (< 30 nanometers) Study Region: Mobile Transects and Fixed Monitoring Site Locations Mobile Monitoring Platform Parameter Instrument Mobile and Fixed sampling: Particle number concentration (35 nm – 1 µm) P-Trak 8525, w/ diffusion…

In April 2020, the FAA submitted a report to Congress in response to Sections 173 and 188 of the FAA Reauthorization Act: https://www.faa.gov/about/plans_reports/congress/media/Day- Night_Average_Sound_Levels_COMPLETED_report_w_letters.pdf. The conclusion of the report is that the DNL continues to be the recommended metric. The FAA has not released the "noise annoyance survey" to-date. Overflight noise/human health study FAA Reauthorization Implementation Help shape the scope and implementation of the study No update at this time. Environmental Pilot Program FAA Reauthorization Implementation Help shape the scope of the grant program, and secure funding for an innovative local pilot for mitigation The US House of Representatives passed its FY21 appropriations legislation that included direction for the FAA to "implement the Environmental Mitigation Pilot Program" as required in the FAA reauthorization bill. Negotiations with the US Senate are ongoing. Air Traffic Noise and Pollution Expert Consensus Act Legislation Advocate for passage No update at this time. Protecting Airport Communities from Particle Emissions Act Legislation Advocate for passage The US House of Representatives-passed HR 2, the Moving Forward Act, includes this legislation as an amendment. Negotiations with the US Senate are ongoing. Secondary Insulation for "Failed" Packages Legislation Advocate for passage US Representative Adam Smith is currently finalizing this legislation for introduction. In addition, the US House of Representatives passed its FY21 appropriations legislation that included direction to the FAA to "consider residences that were mitigated prior to 1993 with sound insulation as 'unmitigated' if an airport can verify that the residences continue to fall within the latest day-night…

• Two Noise Abatement Departure Profiles (NADPs) are followed domestically and internationally: the Close-in and Distant departure profiles • A Close-in NADP is more beneficial in abating noise in areas closer to the runway end; while a Distant NADP is more beneficial in abating noise in areas farther down the departure corridor • A Distant NADP appears to provide the most benefits to the developed areas in the SEA environs Key Points esassoc.com PORT OF SEATTLE Presentation Overview • Introduction • Background on Abatement Departure Profiles • Review the SEA NADP Noise Analysis Results • Recommendations • Respond to Questions from StART Members esassoc.com PORT OF SEATTLE • To determine the NADPs currently in use at Seattle-Tacoma International Airport (SEA), ESA surveyed five airlines operating Boeing 737-800s at SEA • The existing NADPs were normalized to Stage Length 4 conditions and aircraft noise exposure was modeled using the Aviation Environmental Design Tool (AEDT) • ESA compared the Sound Exposure Level (SEL) Contours and Grid Point values for the Close-In and Distant NADPs for four runway ends: 16L, 16C, 34R, and 34C • The analysis identified a preferred NADP for use at SEA Introduction esassoc.com PORT OF SEATTLE • After the technical work was completed and presented to the StART Working Group on October 14, 2019, Delta Air Lines conducted a internal review of its response to the NADP Survey • As a result of that review, Delta Air Lines determined that its survey response incorrectly reflects the NADP that it…
