TagSea-Tac Airport(286)

The Port of Seattle provides one of the most comprehensive noise management programs in the nation with Sea-Tac’s noise abatement and mitigation measures. Sea-Tac’s nois'e programs are divided into Noise Abatement and N–oise Remedy. Noise abatement programs relate directly to noise reduction at the source – models of aircraft and engine types at Sea-Tac, fliGht procedures, ground noise restrictions, etc.. Noise remedy programs are those that mitigate the effects of noise in the impacted co'mmunities. These type of programs include sound insulation of homes, sales assistance and the home acquisition and relocation program. NOISE ABATEMENT PROGRAMS Noise Budget This program guarantees that Sea-Tac will move steadily and predictably toward an all Stage 3 (the quietegt) jet fleet, reducing noise each year over the next 10 years. The “budget” allocates the maximum amount of noise that-airlines are allowed to make each year at Sea.-Tac and this allocation is reduced annually. Since the inception of the program in January 1 991 , Sea-Tac's Stage 3 fleet mix has increased from 50% to 85%. The national Stage 3 fleet mix in 1996 was 70%. .e Nighttime Limitations This program, Qhich went into effect Oct. 1, 1990, phases out Stage 2 (the noisiest) jet aircraft flights during the nighttime hours. Each year the nighttime hours expanded until October 1, 1995. Since 1995, operations'of these jets have been restricted between p.m. and 7 a.m.. Ground Noise Control Powerbacks. Airlines at Sea-Tac are not allowed to use engine power to back away from gates. With the…

The limited scope and nature of the study will yield overly optimistic results. It will not identify the magnitude of the existing water pollution or provide sufficient basis to predict the contamination levels if the Third runway is built. The Expert Noise panel in theory was not suppose to be addressing the Third Runway but in the end their results were twisted and applied to the Third runway. This study needs to openly address Master Plan Update impacts. Detailed Study Area…

The purposes of this agreement are to limit aggregate aircraft noise at Seattle-Tacoma International Airport (SEA) and to reduce it over time. Section b–Effective Date This agnement shall become effective on Januuy 1, 1991. Section 3–Definitions For the purposes of this agreement, the following definidons will apply: 1. Aircraft – Fixed wing airplane operadng in commercial service carrying passengers or cargo. e 2. Aircraft Operation – An aircraft landing or takeoff at the Airport. 3. 4. Aix-pol t – Seattle-Tacoma International Airport (SEA). MMWSUrM£l and MEL – The average daily noise exposure level at the Airp6n prcxluced by the energy sum of the PCANEL and the CCANEL. 5. Ha and ME. – A portion of the Maximum ANEL that has not been allcx:ated and is held by the Port of Seattle for future allocadon to new entrants and existing carders. Noise that reverts to the Port from Dansfer fees and forfeited or abandoned allocations is added to the Airport Noise Fund. The Airport Noise Fund’s . noise exposure level is equal to the numerical difference calculated on an energy basis between the Maximum ANEL (per Section 4. A.) and the allocations of PCNEL and CCNEL made aCcording to this Agreement. 6. Allocated Aircraft Operation – Any aircraft operation that is not defined as a Non- All(x;ated Aircraft Operation (see definidon 29. Non- Allocated Aircraft Operation). 7. Allocation – See PCNEL Allocation and/or C'(-'NEL Allocati e 8 – The total number of Aircraft Operations for aSWcifiedped(xi divided by the number of…

The full name of this study is an FAR Part 1 50 (after Federal Aviation R'eg'ulation Part 1 50) Aircraft Noise and, Land Use Compatibility Stbdy. This mouthful of a title means that the Study will consider and evaluate possible ways to reduce ,the impact of aircraft noise on neighborhoods sUrrounding Sqa:Tac Airport and will work with comfnunities to limit the growth of residential populations within high aircraft noise areas. Th'e Study will identify .existing noise levels, predict future noise levels, evaluate noise abatement and land use alternatives and then' recommend those' which rdalistically can 'be expected to reduce thQ number of people, affected by aircraft noise. h. edule ot Meetina Feb.-Jun. 1997 .NovJ 18, 1997 '(+?S:+:-!

forecast demand. As noted in the FAA guidance, the 1996 Master Plan Update has identified the Port’s capital improvement plan, and provides a realistic assessment of needs for accommodating 15.7 million enplaned passengers, which is expected to now occur in year 2005. The plan also reflects the longer-term needs, associated with 19 million enplanements, in a more conceptual fashion. e q tIl Some of the environmental approvals identified by the Final EIS and this Supplemental EIS, may expire within the next 3-5 years. FAA Environmental Guidelines (FAA Order 5050.4 A, Paragraph 102) states “Time Limitations for Environmental Documents b. With regard to approved final impact statements.....(1) if major steps toward implementation of the oroposed action (such as the start of construction, substantial acquisition, or relocation ctivities) have not commenced within 3 years from the date of approval of the final tatement, a written reevaluation of the adequacy, accuracy, and validity of the final =atement shall be prepared. .. .” The Clean Air Act Conformity rules specifically note that a conformity determination “lapses 5 years from the date of the final conformity determination” (40 CFR Part 51.857(a)).

Additional planning will be undertaken at Sea-Tac in the future, encompassing facility requirements and environmental impacts, based on forecasts of short-term, intermediate ald long-term conditions. If these efforts are undertaken around the year 2000, it is anticipated that aviation industry conditions could stabilize, making air travel demand less volatile mId forecasting less uncertain. jf }…

Port of Seattle Response to Highlin8 Water District letter in Draft E.I.S. for Master Plan Upiate at Seatac International Re: PI F-L LA) Dear Mr. Ossenkop and Ms. Hinkle: The response to our July 27. 1995 letter with regard to specific issues effecting the Highline Water District's existIng and future groundwater Issues were not adequately addressed. The District now has water rights to 17.5 million gallons per daY (MGD) of ground water within the Highline area What steps will be taken by the Port of Seattle to mitigate the contamination of the ground watel? VWlat steps will be taken by the Port of Seattle to mitigate the Ioss of ground wateF lecharge to the aquifers now being used and those that will be used in the future? These two simple questions were not addressed by the Draft Environmental Impact Statement for the Master Plan Update at Seatac InternatIonal Airport. We are expecting a response to our questions which would be acceptable to ou1 District. Sincerely , }h:/ /L &b,,A Keith A. Harris Manager.
