The Puget Soundkeeper Alliance challenged the 2003 water discharge permit issued to Seattle-Tacoma International Airport, arguing that the Port of Seattle had been releasing harmful pollutants — including aircraft de-icing fluids — into Puget Sound without proper treatment or enforceable limits for nearly a decade. The group contended that Washington State's Department of Ecology improperly extended the airport's compliance deadline beyond the legally allowed 10-year period, pushing it from 2004 to 2007. The case centered on whether the permit violated both Washington State law and the federal Clean Water Act.

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.

The Pollution Control Hearings Board ruled largely in favor of community groups ACC and CASE in their challenge to Sea-Tac Airport's water pollution permit, ordering stricter wastewater treatment standards and rejecting most of the Port's appeals. Key victories included requiring the airport to meet long-overdue water quality standards for its industrial wastewater discharged into Puget Sound, mandating improved toxicity testing during de-icing season, and directing a professional wetlands analysis of Lake Reba. Of the seven final directives issued by the Board, six favored the community appellants and only one favored the Port.

The U.S. Army Corps of Engineers has been reviewing a permit application related to a proposed third runway at Sea-Tac Airport, described as the largest Section 404 proceeding the Corps had handled and the biggest public works project in Washington State since the Grand Coulee Dam. Key issues under consideration include the replacement of lost wetlands, streamflow impacts, and the seismic stability of the proposed runway embankment. No deadline exists for the Corps to render its final decision, though draft permit conditions were reportedly being prepared by civilian technicians in the Seattle District Office.

This legal brief was filed by Citizens Against Sea-Tac Expansion before the Washington Supreme Court, challenging a decision by the Pollution Control Hearings Board regarding the expansion of Seattle-Tacoma International Airport. The group argues that state regulators improperly allowed the Port of Seattle to rely on future, unwritten stormwater permits as proof that airport runoff would meet water quality standards, and that regulators wrongly pre-authorized pollution mixing zones in nearby waterways without sufficient oversight. The case centers on whether proper environmental protections were in place before approving the airport expansion project.

The Airport Communities Coalition (ACC) filed an emergency motion seeking to stop the Port of Seattle from moving forward with its Third Runway Project without complying with conditions set by the Pollution Control Hearings Board. This supplemental brief, submitted to the Washington Supreme Court, addresses whether the Administrative Procedure Act's stay provisions apply to ACC's request to enjoin the Port from violating the Board's order. ACC argues that the relevant APA provisions do not directly govern its motion, but that an injunction is especially warranted because the Port failed to obtain a stay of the Board's order.

This document lists 16 permit conditions related to environmental protections at what appears to be a Port development project, showing which conditions were accepted and which were appealed. Conditions covering stormwater management, wetland mitigation, fill criteria, and water quality monitoring were contested, with 8 of the 16 conditions formally appealed. Accepted conditions include stormwater sampling, wetland hydroperiod matching, and long-term contamination monitoring requirements.

The Port of Seattle filed a pre-hearing brief challenging aspects of a 2003 water pollution permit issued by Washington State's Department of Ecology for Seattle-Tacoma International Airport (Sea-Tac). The permit, considered one of the most stringent stormwater permits in the country, sets numeric water quality limits, requires extensive toxicity testing, and mandates upgrades to the airport's stormwater and wastewater management systems. The brief addresses a range of contested issues, including effluent limits, sampling requirements, and construction stormwater controls.

In this 2004 declaration filed with the Washington Supreme Court, Robin V. Kordik, a Senior Environmental Program Manager for the Port of Seattle's Aviation Division, describes efforts to identify wetland mitigation sites near Sea-Tac Airport in connection with the airport's Third Runway construction project. A study by environmental firm Parametrix assessed 89 potential mitigation locations but concluded that no suitable new sites were available in the affected sub-basins that met the Pollution Control Hearings Board's criteria for sustainability and public safety. The declaration was submitted in opposition to a motion for injunctive relief brought by the Airport Communities Coalition.
