    EXH AR023947: Third Runway Update Talking Points — ECY SMT Briefing

    This September 2000 internal briefing document from the Washington State Department of Ecology (ECY) outlines the agency's long-running regulatory review of the proposed Third Runway at Seattle-Tacoma International Airport, covering key environmental concerns such as wetland mitigation, stormwater management, and wildlife hazard management. It describes ongoing conflicts with the Port of Seattle over compliance with environmental permits, including a Clean Water Act Section 401 certification that was heavily conditioned in 1998 and subsequently withdrawn by the Port. The document also notes intensifying political pressure from legislators, the Governor's office, and community opposition groups threatening legal action over perceived environmental violations.

    EXH 364: Letter Columbia Biological Assessments to Ecology CWA §401 Certification STIA Third Runway

    A December 1999 environmental assessment prepared for Citizens Against Seatac Expansion (CASE) concludes that the Port of Seattle failed to provide sufficient scientific evidence to assure compliance with Clean Water Act water quality standards for its Seattle-Tacoma International Airport expansion project. The report found that stormwater runoff from the airport was causing ongoing violations of toxic substances criteria — particularly for copper and zinc — in nearby Miller and Des Moines Creeks, with pollutant levels sometimes exceeding EPA limits by more than tenfold. The author argues that Ecology therefore lacked a scientifically defensible basis to issue a Section 401 water quality certification for the proposed wetland-filling and stormwater management improvements.

    EXH AR024298: Letter to Army Corps Opposing Section 404 Permit STIA Third Runway

    In a November 1999 letter to the U.S. Army Corps of Engineers, the law firm Smith & Lowney submitted comments on behalf of Citizens Against Seatac Expansion (CASE) opposing a permit for the Port of Seattle's proposed Third Runway expansion at Sea-Tac Airport. The letter argues that the permit should be denied because the project would violate federal and state water quality standards, including toxic effluent limits for copper and zinc, and cause significant degradation to U.S. waters. It urges the Corps to consider not only the direct environmental impacts of the proposed fill, but also the cumulative and secondary effects of all current and future airport operations when making its permitting decision.

    Fax to ACC: Port Of Seattle Plans to Haul Rock and Concrete to Sea-Tac Airport Site

    A June 1999 fax from Al Furney to Kristen Stewart of the Airport Communities Coalition (ACC) asks whether ACC members are aware of the Port of Seattle's announced plans to haul rock and concrete to the Sea-Tac Airport site. Furney notes that RCAA (Residents Against Airport Noise, or a related community group) is seeking a copy of Merlino's contract with the Port. The fax was copied to the City of Burien, City of Normandy Park, CASE representative Larry Corvari, and Chris Gower.

    Order Denying Respondent Port Of Seattle’s Motion to Dismiss for Lack of Standing and Staying Action

    In January 1999, the King County Superior Court denied the Port of Seattle's motion to dismiss a lawsuit brought by Citizens Against SeaTac Expansion, ruling that a potential injury from wetland filling near the airport could not be ruled out. The case centered on the Port's plan to fill wetlands in Auburn as part of its Master Plan Update, which included construction of a proposed third air carrier runway at Seattle-Tacoma International Airport. The court stayed all further proceedings until the U.S. Army Corps of Engineers issued a final decision on the Port's wetland-filling permit under Section 404 of the Clean Water Act.

    Port Of Seattle’s Memorandum Supporting Proposed Order: CASE v. Port Of Seattle (No. 98-2-23944-1 SEA)

    In January 1999, the Port of Seattle filed a legal memorandum in King County Superior Court supporting a proposed order to stay (pause) a lawsuit brought by Citizens Against SeaTac Expansion (CASE) regarding the expansion of Seattle-Tacoma International Airport. The central dispute concerned the construction of a proposed third runway and the filling of nearby wetlands, with the Port arguing that court proceedings should be paused until the U.S. Army Corps of Engineers issued a final decision on the Port's wetland-fill permit under Section 404 of the Clean Water Act. The two parties disagreed on the exact language defining how long the stay should last, with the Port seeking a clear end date tied to the Corps' permit decision and CASE proposing broader conditions related to Port environmental decisions.

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.
