    EXH AR024551: Letter Jay J. Manning (Marten Brown) to PCHB Presiding Officer — Appeal Water Quality Certification #1996-4-02325 & Stipulated Agreement Order of Dismissal

    In September 2001, attorneys for the Port of Seattle filed an appeal of Water Quality Certification #1996-4-02325, issued by the Washington State Department of Ecology for improvements at Seattle-Tacoma International Airport, including construction of a third runway. Simultaneously, the Port and the Department of Ecology filed a Stipulated Agreement and Agreed Order of Dismissal, resolving the Port's appeal by agreeing to amend the water quality certification. The Port requested that the Pollution Control Hearings Board accept the stipulation, dismiss the Port's appeal, and allow the separate Airport Communities Coalition appeal to proceed using the revised certification.

    EXH AR023886: FW: Summary Runway Stipulated Agreement

    A September 2001 internal email summarizes a Stipulated Agreement between the Washington State Department of Ecology and the Port of Seattle regarding the third runway construction at Sea-Tac Airport. The agreement clarifies the scope and duration of water quality certification conditions (401 permit), including perpetual wetland mitigation requirements, 15-year wetland monitoring, and rules governing fill material approval and stormwater management. Key changes also address hydrologic monitoring schedules, buffer requirements, and reporting frequency to ensure environmental protections remain in place during and after construction.

    EXH AR023915: Notice of Appeal — §401 CWA Certification & CZMA Concurrence (PCHB No. 01-133)

    In September 2001, the Port of Seattle filed a Notice of Appeal before Washington State's Pollution Control Hearings Board, challenging conditions attached to Ecology's §401 Clean Water Act certification for the construction of a third parallel runway at Seattle-Tacoma International Airport. The appeal document argues that Ecology's certification already fully protects Washington's water resources and that the project had undergone more than a decade of rigorous planning, environmental review, and judicial scrutiny before receiving approval. The filing was prepared by the law firm Foster Pepper & Shefelman and was shared among legal and agency representatives as a confidential, attorney-client privileged communication tied to ongoing settlement discussions.

    EXH 277: Email Chain – Proposed Language Condition E(1)(b) Third Runway Fill Criteria SPLP Testing Drainage Layer Cover

    In September 2001, representatives from the Port of Seattle and the Washington Attorney General's office exchanged emails negotiating the language of Condition E(1)(b), which governs fill material criteria for an embankment construction project. The proposed language would allow the Port to use a 'drainage layer cover' design and to demonstrate fill suitability through Synthetic Precipitation Leaching Procedure (SPLP) testing as an alternative to standard fill limitations. Under the proposal, SPLP test results would be submitted to the Washington Department of Ecology at least ten business days before any fill placement.

    EXH 447: Draft Settlement Agreement — §401 Cert #1996-4-02325 Appeal, Sep 2001

    This September 2001 draft settlement agreement between the Washington State Department of Ecology and the Port of Seattle addresses conditions attached to a Clean Water Act §401 Certification for the construction of a third runway at Seattle-Tacoma International Airport. The agreement clarifies and revises specific environmental conditions — including wetland mitigation, stormwater management, and groundwater monitoring requirements — that would remain in effect during and after construction. The Port agreed to file a formal appeal solely to implement the settlement, after which the parties would jointly request the Pollution Control Hearings Board approve the agreed-upon modifications and dismiss the appeal.

    This September 2001 draft settlement agreement between the Washington State Department of Ecology and the Port of Seattle addresses the Port's appeal of a Clean Water Act §401 Certification issued for the construction of a third runway at Seattle-Tacoma International Airport. The agreement clarifies and revises several certification conditions related to wetland mitigation, stormwater management, and groundwater monitoring. Both parties agreed to jointly request that the Pollution Control Hearings Board amend the certification accordingly, after which the Port's appeal would be dismissed.

    EXH AR023887: WA Dept of Ecology SEA/NWRO Environmental Programs Monthly RP Aug 2001

    In August 2001, Washington State's Department of Ecology issued a 401 water quality certification to the Port of Seattle for the proposed SeaTac Third Runway, permitting construction of an 8,500-foot parallel runway involving fill of nearly 20 acres of wetlands and development of 700 acres of upland area. The certification imposed strict stormwater management and wetland mitigation conditions, including 201 acres of wetland creation and riparian restoration. The certification was subsequently appealed by the Airport Communities Coalition on August 23, 2001, with a hearing before the Pollution Control Hearings Board scheduled for March 2002.

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.
