TagSea-Tac Noise Abatement Committee(4)

This quarterly Sea-Tac Noise Abatement Report from the Port of Seattle (Q4 1992) tracks progress in reducing airport noise, highlighting that 71% of jet flights were operated by quieter Stage 3 aircraft, up from 63.4% the previous quarter. All airlines stayed within their allocated noise budgets, and new nighttime restrictions effective October 1, 1992 limited louder Stage 2 jets between midnight and 6:00 a.m. The report also outlines noise abatement flight procedures designed to route departing and arriving aircraft over industrial areas and water to minimize noise impacts on surrounding communities.

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 1990 document outlines a comprehensive package of noise abatement actions for Seattle-Tacoma International Airport, agreed upon by a Mediation Committee on March 31, 1990. It covers measures such as nighttime flight restrictions, soundproofing programs for nearby homes and public buildings, improved flight corridors, and a new noise management monitoring system. According to the technical consultant involved, full implementation of these agreements could reduce noise levels by approximately 50% for communities surrounding the airport.

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.
