In December 1996, the Port of Seattle submitted a Section 404 permit application to the U.S. Army Corps of Engineers to place fill material into wetlands at Seattle-Tacoma International Airport as part of its Master Plan Update, which included construction of a third parallel runway. The proposed runway, located 2,500 feet west of the existing runways, was intended to address severe arrival delays during poor weather conditions, which reduced airport capacity from 60 to as few as 24 arrivals per hour roughly 44% of the year. The application was the result of nearly a decade of regional planning, environmental review, and public involvement, including studies confirming that no feasible supplemental airport sites existed in the four-county region.

HNTB-prepared Final Draft Phase I study (November 1996) for Sea-Tac Airport Third Runway fill material alternative delivery methods. Evaluates transport corridors including Corridor 1 (Des Moines Creek barge transfer and land conveyor), Corridor 2 (SR 509 conveyor, truck, rail), and Corridor 3 (SR 518 conveyor, truck, rail). Covers technical viability, construction/environmental permitting (local, state, federal),

This 1996 document summarizes public responses to a proposed modification of the water discharge permit (NPDES Permit No. WA-002465-1) for Sea-Tac International Airport, operated by the Port of Seattle. It addresses concerns raised at a June 1996 public hearing in Burien, WA, including questions about self-monitoring of water samples, erosion and water flow in Miller Creek, and the Department of Ecology's enforcement and fining process. The document outlines how Ecology responded to community concerns and describes permit changes, such as a new condition requiring the Port to assess the airport's impact on local creek hydrology.

In a 1996 letter to the Federal Aviation Administration, the U.S. Environmental Protection Agency (EPA) Region 10 raised concerns about air quality impacts from the proposed Master Plan expansion at Seattle-Tacoma International Airport, noting that the project was projected to worsen carbon monoxide levels at nearby intersections in violation of federal air quality standards. The EPA called for a comprehensive emissions inventory, a comparison of air quality with and without the project, and enforceable mitigation measures, while also highlighting inconsistencies in air quality modeling across multiple related development projects in the airport area. The agency urged the FAA and Port of Seattle to coordinate data sharing with regional authorities and establish a long-term air quality monitoring program to address cumulative impacts from surrounding projects.

A 1996 air quality review commissioned by the Airport Communities Coalition challenges the FAA's finding that Sea-Tac Airport's Master Plan Update would not worsen air pollution. Envirometrics, Inc. found that if the proposed third runway increased airport operations—by up to 33% annually and 50% during peak hours—carbon monoxide (CO) and nitrogen dioxide (NO₂) levels would exceed federal air quality standards at multiple locations near the airport. The report concludes that these increased emissions from greater aircraft and vehicle traffic would delay attainment of ambient air quality standards in the surrounding communities.
