This community newsletter from the RCAA (Residents for a Cleaner Airport Area) outlines how Highline-area communities near Seattle's Sea-Tac Airport have held the Port of Seattle accountable for noise, water pollution, and runaway construction costs on a proposed third runway. Key victories include a $150 million noise-mitigation settlement for Highline schools, a court-ordered halt to third-runway construction due to unmet environmental permit requirements, and improved water quality in local streams. The document urges residents to stay engaged, warning that the Port continues to pursue runway expansion despite being $3 billion in debt and facing ongoing legal and environmental challenges.

In 2003, Washington State's Department of Ecology issued a water pollution permit (NPDES No. 002465-1) for Sea-Tac International Airport, which was then challenged by multiple parties including the Port of Seattle and several community groups. The appeals, heard in July 2004, centered largely on concerns about aircraft deicing and anti-icing chemicals being discharged into Puget Sound and nearby waterways, where they can deplete dissolved oxygen levels critical to aquatic life. The Pollution Control Hearings Board reviewed the permit's terms and conditions to determine whether adequate environmental protections were in place.

This document tabulates public comments received during a permit review process, likely related to a construction or development project near Sea-Tac Airport. A total of 509 individuals opposed the permit, while 101 supported it, with additional concerns raised across topics including MSE wall integrity, wetlands, hydrology, air and noise pollution, and airport/aircraft safety. The index identifies specific commenters — ranging from environmental consultants to aviation industry groups — and maps each comment to a designated paragraph number for formal review response.

The Airport Communities Coalition (ACC) filed an emergency motion asking the Washington Supreme Court to temporarily halt construction of a proposed third runway at Seattle-Tacoma International Airport. ACC sought to prevent the Port of Seattle from filling wetlands and the Department of Ecology from approving embankment construction while the court's decision on related appeals remained pending. The motion was prompted by reports that the Port planned to begin depositing fill material in April, before the court had issued its ruling.

This declaration, filed before the Washington Supreme Court, was submitted by environmental scientist Dyanne Sheldon in support of the Airport Communities Coalition's emergency request to halt any construction or environmental changes at the Sea-Tac Airport expansion project site. Sheldon, who has over 20 years of wetland ecology expertise and helped establish King County's first wetland management program, argues that the wetlands at the project site cannot be recreated or adequately compensated for if destroyed. The motion asks the Court to maintain the status quo while appeals of a Pollution Control Hearings Board order are decided.

The Airport Communities Coalition filed an emergency motion asking the Washington Supreme Court to block the Port of Seattle from filling wetlands and rerouting Miller Creek in preparation for a third runway at Sea-Tac Airport. The Coalition argued that the Pollution Control Hearings Board's order is legally binding on the Port and the Department of Ecology, and that the Port cannot alter the site's status quo while the appeal is pending. The motion sought an injunction to preserve existing conditions until the court issued a final ruling on whether the project complies with state water quality standards.

Dr. Stephen L. M. Hockaday, a Professor Emeritus of Civil and Environmental Engineering at Cal Poly San Luis Obispo with over 25 years of airport and airspace planning experience, submitted this declaration in support of the Airport Communities Coalition's emergency motion for injunctive relief before the Washington Supreme Court. The case involves the Port of Seattle, the Pollution Control Hearings Board, and the Washington Department of Ecology in a dispute related to Sea-Tac Airport expansion. Dr. Hockaday's credentials include serving as Head of Eurocontrol's airspace and airport modelling service and managing major FAA programs at the nation's ten busiest airports.
