SEA Part 1 5 0 Noise Com patibility Study Review of Public Hearing Held Public Hearing on May 1 5 , 2 0 1 3  Provided summary materials including handout and presentation boards  Offered several ways for the public to comment  Court reporter at the hearing  Comment forms (could be left there or mailed)  Email  Fax  ~ 80 people attended the hearing  16 people made comments to the court reporter  11 left comment forms at the meeting  Received another 40 comments via email/ fax 3

SEA Part 1 5 0 Noise Com patibility Study Review of Public Hearing Com m ents Received on Draft Part 1 5 0  Comments covered a wide range of topics (some outside the scope of the Part 150 Study)  General noise complaints/ concerns  Noise abatement measures (in particular GRE-related comments)  Land use management measures  Part 150 process comments  Environmental related comments  Other comments  Currently in the process of reviewing and preparing responses to the comments 4

SEA Part 1 5 0 Noise Com patibility Study Current Abatem ent Measures Recom m ended to Continue • Measure A-1 : Explore Limited Rescheduling of Nighttime Flights • Measure A-3 : Use VOR Radials to Curb Aircraft Drifting from Noise Abatement Track • Measure A-1 1 : Preferential Runway Use • Measure A-1 5 : Use of FMS Procedures • Measure A-1 6 : Use of Ground Equipment to minimize use of auxiliary power units 8

SEA Part 1 5 0 Noise Com patibility Study Current Abatem ent Measure Recom m ended to Continue w ith Modifications Measure A-1 0 : Maintenance Run-up Regulations  Continue measure with modifications if Ground Runup Enclosure is constructed  Minimal administrative and operational costs Measure A-1 2 : Developm ent/ I m plem entation of a Fly Quiet Program  Continue measure with modification to expand program per Measure A-19 9

SEA Part 1 5 0 Noise Com patibility Study New Recom m ended Abatem ent Alternatives Measure A-1 8 : Construct a Ground Runup Enclosure at the airport to minimize run-up noise Measure A-1 9 : Expand the Fly Quiet Program with new elements Refined GRE Locations B A E D C F = Site eliminated from consideration 1 0

SEA Part 1 5 0 Noise Com patibility Study Current Mitigation Measures Recom m ended to Continue Measure M-2 b: Insulation of Schools Measure M-5 : Property Advisory Service Measure M-6 : Local Government Remedy Support Measure M-7 : Funding for Land Use/ Noise Compatibility Planning Measure M-1 1 : Approach Transition Zone Acquisition 1 1

SEA Part 1 5 0 Noise Com patibility Study Current Mitigation Measures Recom m ended to Continue w ith Modification Modify the Noise Rem edy Boundary  The Noise Remedy Program boundary in use at Sea-Tac is based on the 2000 noise exposure contours developed for the 1985 Part 150 Study.  This Part 150 update has developed noise exposure contours for Future (2018) conditions that are substantially smaller than the previous contours from the 1985 Part 150 Study due to improved engine technology and changes in aircraft operations.  All eligible homeowners located within the existing Noise Remedy Boundary but outside of the modified Noise Remedy Boundary that request participation have been notified and given the opportunity to participate. 1 2

SEA Part 1 5 0 Noise Com patibility Study Current Mitigation Measures Recom m ended to Continue w ith Modification Measure M-2 a: Standard I nsulation – Continue measure for eligible housing units within the modified Noise Remedy Boundary. Where feasible, the Port may include air conditioning as one element of new sound insulation installations. Measure M-1 2 : Prepare Cooperative Developm ent Agreem ents – The process should continue to address development potentials for other areas included within the recommended modified Noise Remedy Boundary. 1 4

SEA Part 1 5 0 Noise Com patibility Study New Recom m ended Mitigation Measures Measure M-1 4 : Sound insulate owner-occupied multi-family units (condominiums) within the revised noise remedy boundary Measure M-1 5 : Conduct Pilot Program to sound insulate renter-occupied multi-family units (apartments) within the revised noise remedy boundary Measure M-1 6 : Conduct Pilot Program to offer avigation easements to owners of individual lots in which mobile homes are located and working with jurisdictions to discourage this type of infill development in the future Measure M-1 7 : Initiate a formal study to evaluate the noise levels at various churches/ places of worship located within the recommended noise remedy boundary for eligibility for sound insulation. 1 5

SEA Part 1 5 0 Noise Com patibility Study New Recom m ended Managem ent Measures Measure P-1 : Evaluate Noise Monitoring and Flight Tracking System for Potential Upgrades Measure P-2 : Periodically review and, if necessary, update the Noise Exposure Maps (NEMs) and the Noise Compatibility Program (NCP). Measure P-3 : Continue to operate the Noise Office. 1 6

SEA Part 1 5 0 Noise Com patibility Study Part 1 5 0 Process  Major steps left to accom plish  Prepare Preliminary Draft Part 150 for FAA review and comment  Update Part 150 Study based on FAA comments  Publish Draft Part 150 document and advertise availability.  Publishing starts a public comment period (at least 45 days)  Schedule, advertise, and hold a public hearing  Review all comments received during the comment period and at the public hearing ( occurring now )  Update the document based on those comments  Commission approves Final Part 150 for submittal to FAA ( anticipating August )  Submit a Final Part 150 document to FAA for review and approval ( anticipating Septem ber )  FAA will take ~ 8 months to issue a Record of Approval 1 7
