    EXH AR023054: ACC Wetland Scientist Letter to Army Corps – Wetland 44a & SR509 Temp Interchange

    An independent wetland scientist, writing on behalf of the Airport Communities Coalition, raised concerns with the US Army Corps of Engineers about potential mapping errors affecting Wetland 44a near the proposed SR509 Temporary Interchange for Sea-Tac Airport's Third Runway project. The letter warned that discrepancies between engineering drawings and actual field conditions could mean the wetland was closer to the construction zone than documented, risking illegal filling or sediment discharge into protected wetlands. The scientist urged the Corps to verify the wetland's true location and review erosion control measures before approving any construction permits.

    EXH AR023618: Letter Kevin L. Stock (Helsell Fetterman) to Dir. Tom Fitzsimmons (Ecology) Re: 1999 Agreed Order & 401 Certification Process

    In this March 30, 2001 letter, attorney Kevin L. Stock of Helsell Fetterman writes to Washington State Department of Ecology Director Tom Fitzsimmons on behalf of the Airport Communities Coalition, confirming agreements reached at a March 27 meeting regarding Sea-Tac Airport expansion. The letter asserts that Ecology's 1999 Agreed Order with the Port of Seattle must be fulfilled before a Section 401 water quality certification can legally be issued, and confirms Ecology's commitment to hold a follow-up technical meeting with key staff and legislators present. The ACC argues that strong scientific and legal grounds preclude issuing a defensible 401 certification until the Port completes its obligations under the Agreed Order.

    A March 15, 2001 laboratory report from Columbia Analytical Services sent to John Strand of the Airport Communities Coalition, summarizing water quality test results from samples submitted on February 28, 2001. The report, assigned service request number K2101434, confirms all analyses were conducted under the laboratory's quality assurance program. It includes reference sheets defining technical acronyms and data qualifiers used in interpreting inorganic, metals, and organic test results.

    EXH 403: GeoSyntec Letter to Army Corps & WA Ecology — Nisqually Earthquake Implications STIA Third Runway MSE Wall & Embankment Fill

    Following the Nisqually earthquake of February 28, 2001, GeoSyntec Consultants wrote to the U.S. Army Corps of Engineers and Washington State Department of Ecology raising serious concerns about the seismic safety of the proposed Third Runway expansion at Seattle-Tacoma International Airport. The letter highlighted that the earthquake caused damage to mechanically stabilized earth (MSE) walls and widespread liquefaction despite being only a moderate event, reinforcing earlier warnings about flaws in the project's seismic design criteria and ground motion analysis. GeoSyntec argued that the airport's role as a regional emergency lifeline demands higher safety standards than those applied to ordinary residential structures.

    Beware – The Great Wall of Sea-Tac and Coalition appeals permit for 3rd runway

    Two 2001 Seattle Post-Intelligencer articles raise safety and environmental concerns about SeaTac Airport's proposed third runway. The first warns that a planned 15-story, 1,450-foot retaining wall built on weak, earthquake-prone soils could catastrophically fail in a seismic event, threatening wetlands and salmon-bearing streams. The second reveals that state officials approved a key water-quality permit for the runway without following their own attorney's advice to secure a water right, prompting the Airport Communities Coalition to appeal the permit and allege political pressure was driving the project forward.

    EXH AR023562: ACC Comment Letter NPDES Permit Major Modification STIA

    A March 2001 letter from Water Resources Consulting LLC to the Washington State Department of Ecology raises concerns about a proposed NPDES permit modification for SeaTac Airport, arguing that the draft permit gives the Port of Seattle a 'blank check' to discharge pollutants at unspecified locations into unnamed water bodies without adequate public oversight. The letter also criticizes the airport's stormwater monitoring reports for obscuring potential water quality violations by mishandling hardness data used to evaluate dissolved metals concentrations. The author urges the Department of Ecology to require specific discharge locations and proper concurrent hardness reporting before issuing the modified permit.

    EXH AR023614: ACC Letter to Ecology – No Enforcement Agreed Order #97TC-N122, 401 Certification Implications

    A March 9, 2001 letter from law firm Helsell Fetterman, representing the Airport Communities Coalition (cities of Burien, Des Moines, Federal Way, Normandy Park, Tukwila, and the Highline School District), demands that Washington State Department of Ecology enforce a 1999 Agreed Order requiring the Port of Seattle to complete groundwater contamination studies at Sea-Tac Airport. The coalition argues that the Port has failed to finish required groundwater flow and contaminant transport studies — originally due December 1999 — and that Ecology cannot legally certify the third runway project under the Clean Water Act without this data. The letter also requests a State Auditor review of how the Port spent grant money provided by Ecology to fund those studies.

The report includes standard data qualifiers and acronym definitions used to interpret inorganic, metals, and organic analytical results. All analyses were conducted under the laboratory's quality assurance program.

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.
