Part 150 Study 2002 Update Sea-Tac International Airport

The Noise Compatibility Plan (NCP) for Seattle-Tacoma International Airport (Sea-Tac) includes measures to abate aircraft noise, control land development, mitigate the impact of noise on non- compatible land uses, and implement and update the program. Federal Aviation Regulation (FAR) Part 150 requires that the plan apply to a period of no less than five years into the future, although it may apply to a longer period if the sponsor so desires. The airport sponsor has requested that the program measures be applied to the current conditions NEM (Figure C40) because it covers a larger area for potential mitigation. The NCP discusses the possibility of the third runway becoming operational but neither the current conditions nor the 2004 NEM (figure F1) shows this runway layout. However, there is a measure in the NCP to reevaluate the NCP measures once the runway becomes operational. The objective of the noise compatibility planning process has been to improve the compatibility between aircraft operations and noise-sensitive land uses in the area, while allowing the airport to continue to serve its role in the community, state, and nation. The approval actions listed herein include all those that the airport sponsor recommends be taken by the Federal Aviation Administration (FAA). It should be noted that the approvals indicate only that the actions would, if implemented, be consistent with the purposes of Part 150. These approvals do not constitute decisions to implement the actions. Subsequent decisions concerning possible implementation of these actions may be subject to applicable environmental…
