    Notice of appeal – Airport Communities Coalition v. State of Washington, Department of Ecology, and Port Of Seattle

    The Airport Communities Coalition (ACC) — representing the cities of Burien, Des Moines, Federal Way, Normandy Park, Tukwila, and the Highline School District — filed a formal appeal challenging Washington State's 2004 Clean Water Act certification for the Port of Seattle's proposed third runway at Seattle-Tacoma International Airport. The coalition argued that the certification violated Supreme Court mandates and water quality laws by allowing contaminated fill material to be used in construction, threatening nearby streams and wetlands. The appeal was submitted to the Pollution Control Hearings Board for the State of Washington.

    Demand for compliance by the Port and Ecology with the decision of the Washington Supreme Court in Port Of Seattle, et al. v. Pollution Control Hearings Board, et al.

    A May 2004 legal letter from Helsell Fetterman attorneys demands that the Port of Seattle and Washington State Ecology Department comply with a Washington Supreme Court ruling before proceeding with third runway construction at Sea-Tac Airport. The court imposed environmental conditions requiring that fill materials used in construction come only from uncontaminated sites, meet strict groundwater quality standards, and pass SPLP leachate testing against both surface and groundwater criteria. The letter argues that the Port's existing work plans and bid documents violate these court-mandated conditions, citing discrepancies such as the Port's allowable arsenic limit of 14.75 ug/L being several hundred times higher than the court-required 0.05 ug/L standard.

    Letter to Peter Eglick re ACC v. Graves, et al., No. 04-35011 (9th Cir.)

    In a May 26, 2004 letter, Port of Seattle Senior Counsel Traci M. Goodwin notified attorney Peter Eglick that the Port planned to begin construction of a third runway at Sea-Tac Airport on or before June 7, 2004, following a Washington State Supreme Court ruling affirming Ecology's Clean Water Act certification. The letter references the case ACC v. Graves (9th Cir. No. 04-35011) and warns opposing counsel of the Port's construction timeline under Ninth Circuit Rule 27-3, which requires advance notice when a party may seek emergency relief within 21 days.

    Declaration of Peter J. Eglick in support of respondent/cross-petitioner Airport Communities Coalition’s reply in support of its emergency motion for injunctive relief pursuant to RAP 8.3

    In April 2004, the Airport Communities Coalition asked the Washington Supreme Court to halt construction work on a controversial Sea-Tac Airport runway expansion, arguing that long-standing environmental issues — including concerns about fill contamination and damage to creeks and wetlands — needed to be resolved first. The Port of Seattle maintained that a recently passed state law (SSB 5787) allowed it to proceed with certain work, such as rechanneling Miller Creek, even while the court case was still pending. Coalition attorney Peter Eglick filed a supporting declaration attaching a Seattle Post-Intelligencer article in which the Port's Aviation Director confirmed plans to begin work as early as May or June 2004.

    Declaration of John Rothnie, P.E. in opposition to Airport Communities Coalition’s motion for injunctive relief

    In 2004, John Rothnie, the Port of Seattle's Airfield Program Manager, filed a declaration opposing a request to block construction of a third runway at Seattle-Tacoma International Airport (Sea-Tac). The declaration outlines the Port's years of planning efforts, including obtaining required environmental certifications and developing a detailed Work Plan to ensure fill materials used in the runway embankment met strict water-quality standards. The Port had been moving forward with the expectation of beginning construction in 2004, following approval from the Washington Department of Ecology and the Pollution Control Hearings Board.

    Declaration of Gillis E. Reavis in opposition to Airport Communities Coalition’s motion for injunctive relief

    This document is a Declaration by attorney Gillis E. Reavis filed in the Supreme Court of Washington in a case where the Port of Seattle challenged the Pollution Control Hearings Board, Airport Communities Coalition, and Citizens Against SeaTac Expansion. The declaration opposes a motion for injunctive relief and attaches excerpts from the U.S. Army Corps of Engineers' Record of Decision for a Port of Seattle Section 404 wetlands permit (1996-4-02325), which covers environmental reviews under the Clean Water Act, Endangered Species Act, and other federal statutes related to airport expansion. The underlying dispute centers on regulatory approvals for Sea-Tac Airport development and its environmental impacts on surrounding communities.

    Declaration of Robin V. Kordik in opposition to Airport Communities Coalition’s motion for injunctive relief

    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.

    Declaration of Michael Feldman in opposition to Airport Communities Coalition’s motion for injunctive relief

    This 2004 declaration by Michael Feldman, Deputy Managing Director of the Port of Seattle's Aviation Division, was submitted to the Washington State Supreme Court in opposition to a motion for injunctive relief filed by the Airport Communities Coalition. Feldman, who oversaw technical, environmental, and regulatory compliance at Seattle-Tacoma International Airport (Sea-Tac), describes the airport's Master Plan — adopted in 1996 — which includes the addition of a third runway and other facility expansions to address growing regional air travel demand. The declaration provides context for the decade-long planning and environmental review process behind Sea-Tac's expansion efforts.

Sea-Tac Airport is currently undergoing the largest and longest expansion in its history, collectively known as the Sustainable Airport Master Plan (SAMP). Some of it you can already hear, but you’re probably not aware of what it all means. Here’s what you need to know.

As the source for federal transportation grants, the Puget Sound Regional Council was charged with developing a system to meet the growing need for commercial aviation. When the search for a second airport failed, they authorized the Port of Seattle to build the Third Runway, with a mandate to develop a noise abatement and mitigation program. In their effort to stop the Third Runway, the ACC argued over every detail of the Port's efforts--including property buyouts and sound insulation. The dispute was meant to be settled by a three member Expert Arbitration Panel. This is their final report. It finds 2-1, that the Port's program was insufficient in several respects. Despite that, funding for the Third Runway was approved by the PSRC, and the 'Port Package' program, proceeded largely unchanged. Expert Arbitration Panel's final decision finding that the Port of Seattle had not shown sufficient reduction in real on-the-ground noise impacts to satisfy noise reduction conditions required for approval of a third runway at Sea-Tac International Airport. The majority decision concluded the Port's noise abatement programs were insufficient despite being impressive in scope.
