TagPart 150(117)

This catalog lists documents received in 1993 related to Sea-Tac International Airport and regional air transportation policy, covering topics such as airport noise studies, environmental impact statements, and air quality plans for the Puget Sound area. Sources include the FAA, US EPA, Washington State DOE, and various consulting firms. The collection spans noise compatibility programs, aircraft deicing environmental concerns, wetlands restoration, and long-range aviation forecasts for the Pacific Northwest.

This document compares a 1996 Expert Arbitration Panel's findings on aircraft noise at Seattle-Tacoma International Airport with the FAA's 2013-2018 Part 150 Noise Compatibility Program approval, revealing that many of the same unresolved noise abatement and mitigation issues identified decades ago remain unaddressed today. Communities surrounding Sea-Tac — including Burien, Normandy Park, and Des Moines — continue to experience increasing noise and air pollution as flight operations have grown from 387,000 in 1995 to over 438,000 in 2018. The document calls out regulators and the Port of Seattle for failing to make meaningful progress on commitments such as nighttime flight restrictions, engine run-up controls, and departure corridor compliance.

In a September 1, 1992 letter to the FAA Administrator, the Regional Commission on Airport Affairs formally requests reconsideration of the FAA's August 14, 1992 decision approving Passenger Facility Charges (PFCs) at Seattle-Tacoma International Airport. The Commission, representing communities near Sea-Tac severely impacted by aircraft noise, argues that PFC funds should be redirected toward noise mitigation efforts rather than security improvements and preliminary studies, and that local governments were not properly notified or consulted during the PFC application process. The letter calls for increased funding levels for noise mitigation, cancellation of certain approved expenditures deemed inappropriate or excessive, and greater consideration of local government views in future PFC allocation decisions.

This 1985 document, prepared by the Port of Seattle, outlines the Part 150 Airport Noise Compatibility Program for Seattle-Tacoma (Sea-Tac) International Airport. It combines two phases: Phase I, Noise Exposure Maps (officially submitted to the FAA in October 1984), and Phase II, a Noise Compatibility Program adopted by the Port Commission in January 1985. Together, these phases identify noise exposure around the airport and propose measures to address compatibility between aircraft noise and surrounding land uses.

This 1983 FAA Advisory Circular (AC 150/5020-1) provides guidance for airports on noise control and land-use compatibility planning under FAR Part 150 and the Aviation Safety and Noise Abatement Act of 1979. It outlines a standardized system for measuring airport noise, identifying compatible and incompatible land uses near airports, and developing Noise Exposure Maps and Noise Compatibility Programs. Participation in the program is voluntary, and it aims to reduce existing noise conflicts around airports while preventing new incompatible development through cooperation among airport operators, planners, and community members.

This document presents F.A.A. Density Guidelines for North Sea-Tac Park, a neighborhood near Seattle-Tacoma International Airport. It maps out population density limits across different zones, ranging from 1.5 people per acre in the Clear Zone closest to the airport, to 2 people per acre in the Extended Clear Zone, up to 20-40 people per acre in areas farther from the runway. The guidelines reflect FAA safety and noise policy restrictions that limit how many residents can live in areas most directly affected by airport flight paths.
