    EXH AR026623: Ecology Justification Amendment No. 3 Contract C0100121 Shannon & Wilson

    In December 2001, Washington State Department of Ecology drafted a justification to amend its contract with engineering firm Shannon and Wilson, Inc., adding $57,412 to support ongoing review of the Port of Seattle's Natural Resource Mitigation Plan related to the proposed Third Runway project at Sea-Tac Airport. The amendment was needed to cover expert witness testimony before the Pollution Control Hearings Board following an appeal of Ecology's 401 Water Quality Certification, as well as field monitoring of wetland construction and review of revised mitigation documents. Funding for the contract was provided through an interagency agreement with the Port of Seattle and was not approved by the Port Commission until December 11, 2001.

    EXH 450: Ecology Draft Memo Requesting Ching-Pi Wang Review Third Runway Embankment Seepage Groundwater Monitoring Plan

    In December 2001, Ann Kenny of the Washington Department of Ecology's Northwest Regional Office drafted a memo requesting that hydrogeologist Ching-Pi Wang review a groundwater and seepage monitoring plan submitted by the Port of Seattle for the proposed third runway at Seattle-Tacoma International Airport. The plan, titled 'Third Runway Embankment Seepage and Groundwater Monitoring Plan,' was submitted on November 16, 2001, and required expert review before Ecology could approve it. Wang was asked to provide written comments on the plan's adequacy and any recommended changes by January 18, 2002.

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.
