In 1990, the Port of Seattle's Port Commission passed Resolution No. 3062, endorsing an agreement reached by the Seattle-Tacoma International Airport Noise Mediation Committee after 18 months of study by community representatives, airlines, pilots, the FAA, and airport users. The agreement established a Noise Budget and Nighttime Limitations program aimed at reducing aircraft noise levels by at least 50% by 2001 compared to a 1989 baseline, while also expanding the existing Noise Remedy Program to insulate more homes and remove financial burdens from homeowners. The resolution authorized the Executive Director to implement the agreement's terms, including revising airport regulations, entering noise limitation agreements with airline tenants, and installing a Noise Management System to monitor compliance.

This document outlines the Final Package of Mediated Noise Abatement Actions for Seattle-Tacoma International Airport, agreed upon by the Mediation Committee on March 31, 1990. It covers a wide range of noise reduction measures, including nighttime flight restrictions, a noise remedy and insulation program for affected communities, improved flight corridor procedures, and a comprehensive noise management and monitoring system. According to technical consultants, full implementation of these agreements could reduce noise levels by approximately 50% in the communities surrounding the airport.

This 1990 Final Environmental Assessment, prepared by the FAA's Air Traffic Division in Seattle, evaluates proposed changes to arrival and departure flight routes at Seattle-Tacoma International Airport. The document was signed by Air Traffic Division Manager Temple H. Johnson, Jr. on March 27, 1990, and examines the potential environmental impacts of rerouting aircraft traffic in and out of Sea-Tac. It serves as an official federal record relevant to noise and environmental policy affecting communities around the airport.

This 1990 Final Environmental Assessment, published by the U.S. Department of Transportation's Federal Aviation Administration, examines proposed changes to air traffic arrival and departure routes at Seattle-Tacoma International Airport. Volume II of the document compiles public comments received in response to the Draft Environmental Assessment, reflecting community input on how the proposed route changes could affect noise and other environmental conditions in the Seattle, Washington area.

This 1989 FAA draft Environmental Assessment examines proposed changes to arrival and departure flight routes at Seattle-Tacoma International Airport, aimed at reducing air traffic congestion and improving airspace efficiency. The document identifies a key inefficiency: during good weather and peak demand, south-landing capacity (42 aircraft/hour) was significantly lower than north-landing capacity (56 aircraft/hour), largely due to a requirement routing turbojet aircraft through Elliott Bay. The assessment traces the issue back to noise abatement procedures established since 1970 that prioritized limiting jet overflights in certain Seattle metropolitan areas over operational efficiency.

In April 1989, the Port of Seattle Commission passed Resolution No. 3042 authorizing the Executive Director to enter into an agreement with the Puget Sound Council of Governments (PSCOG) to develop a long-term regional air carrier system plan for the Puget Sound area. The resolution was prompted by a recognized need for additional air carrier capacity beyond the year 2000, following a 1988 Airspace Study Update of Seattle-Tacoma International Airport. The agreement allowed the Port to seek federal FAA funding and hire consultants to study long-term aviation capacity options for the region.
