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…

Elements of Part 150 Noise Compatibility Programs and Community Roundtables Information Sheet Changes in airport operations, airspace procedures, aviation infrastructure, and technology can have impacts on communities. Part 150 studies and community roundtables are two methods by which airports and the FAA can help communities understand and participate in recommending changes to aviation services in their community.1 There are benefits to each approach, and many airports could be well-served by employing both strategies in a complementary manner. For example, an airport that is preparing to update its Part 150 program may be well-supported if there is already an effective roundtable in place, leading to more effective community participation in the Part 150 process. Similarly, a community roundtable may benefit from the periodic benchmarking and documentation of conclusions in a formal, approved Part 150 Noise Compatibility Program. Since 1983, more than 275 airports nationwide have taken advantage of the voluntary Part 150 Noise Compatibility Program, which provides a structured process for airports to engage with communities, airlines and other user groups as well as the FAA, with the goal of reducing incompatible land uses. A Part 150 study is a discrete undertaking intended to involve all stakeholders in evaluating current and future noise impacts, and identifying measures to mitigate them. It can result in recommendations for strategies to improve noise compatibility of existing and future development around airports such as changes in flight procedures and local zoning, land acquisition, sound insulation, and others. Federal funding for some solutions, such as sound…

StART enhances cooperation between the Port of Seattle and the neighboring communities of Sea-Tac Airport December 11, 2019 Recap The Sea-Tac Stakeholder Advisory Round Table (StART) meeting took place on December 11, 2019 with a focus on discussing the results of the Noise Abatement Departure Profiles Noise Analysis, recapping the Federal Policy Working Group’s and Aviation Noise Working Group’s meetings, and getting an update on the end-around taxi procedure. This voluntary, advisory roundtable, convened by Seattle-Tacoma International Airport Managing Director Lance Lyttle, is a venue for the Port of Seattle to engage with the communities of SeaTac, Burien, Des Moines, Normandy Park, Tukwila and Federal Way. Representatives from Delta Air Lines, Alaska Airlines, and Lynden Transport are also members. The Federal Aviation Administration (FAA) participates as a non-member. The Airport Operations Director, Laurel Dunphy, chaired the meeting in the absence of Lance Lyttle. Dunphy acknowledged and thanked two of the community representatives who will not be returning in 2020 - Trina Cook, Tukwila community representative, and Earnest Thompson, Normandy Park community representative. She also announced that Port representatives will be meeting with representatives from the cities who have temporarily suspended their involvement in StART on December 17. Dunphy reviewed several StART accomplishments in 2019 and shared that Lyttle is committed to continuing the work with the communities. Dunphy reminded cities that StART community representative terms are up at the end of the year and that cities can re-nominate current members or nominate new members to serve on StART. It was…

We are writing to share our priorities for implementation of the Subtitle D—Airport Noise and Environmental Streamlining section of the Federal Aviation Administration (FAA) Reauthorization Act of 2018. We look forward to your swift and successful completion of these provisions. Seattle-Tacoma International Airport (Sea-Tac) is the 8th busiest airport in the country in terms of passenger volumes and one of the fastest growing – increasing from approximately 31 million travelers served in 2010 to almost 50 million last year. The airport plays a vital role in the region’s ongoing economic vitality, but this growth is straining the capacity of our airport and having significant impacts on our communities. For this reason, the Port of Seattle (which owns and operates Sea-Tac) and the six cities immediately surrounding the airport have identified federal policies, regulations and programs we believe are essential to help address local community concerns. In particular, we have looked at the 2018 FAA Reauthorization Act’s noise provisions as a way to substantively move forward on noise abatement and mitigation. As existing law with definitive deadlines for action, these items provide the most near-term opportunities for progress. While all of the Subtitle D noise provisions are important, we have identified three top priorities – 1) the provisions related to evaluation of the 65 DNL noise standard (sections 173, 187 and 188), 2) the study of the impact of overflight noise on human health (section 189), and 3) the proposed environmental mitigation pilot program (section 190). The timely and effective execution…

We look forward to working with you and your staff toward swift and successful completion of these provisions. Seattle-Tacoma International Airport (Sea-Tac) is the 8th busiest airport in the country in terms of passenger volumes and one of the fastest growing – increasing from approximately 31 million travelers served in 2010 to almost 50 million last year. The airport plays a vital role in the region’s ongoing economic vitality, but this growth is straining the capacity of our airport and having significant impacts on our communities. For this reason, the Port and the six cities immediately surrounding the airport have identified federal policies, regulations and programs that we believe are essential to help address local community concerns. Specifically, we have looked at two areas of focus: 1) implementation of provisions of the 2018 Federal Aviation Administration (FAA) Reauthorization Act, and 2) passage of legislation that helps address ongoing issues of concern: FAA Reauthorization Provisions While all of the Subtitle D noise provisions are important, we have identified three top…
