    EXH AR041138: Water Quality Criteria for Copper — A Need for Revisions to the National Standard

    Article by John C. Hall, William T. Hall, and Charles J. Simmons published in Water Environment & Technology (June 1997) arguing that EPA’s 1984 and 1993 copper water quality criteria should not be applied directly to municipal effluents (POTWs) because dissolved copper in biologically treated effluents is complexed with organic and inorganic matter and is

    Exhibit AR022300: Port Of Seattle Storm Water Receiving Environment Monitoring Report for NPDES Permit No. WA-002465-1

    This June 1997 report, prepared by the Port of Seattle for Washington State's Department of Ecology, presents storm water receiving environment monitoring results conducted under NPDES Permit No. WA-002465-1. It covers water quality topics including instream toxicity bioassays, sediment quality, identification of pollution sources, metals speciation, vegetation management, and streambank erosion in Miller Creek and Des Moines Creek watersheds near Sea-Tac Airport. The findings assess the environmental impact of airport storm water runoff on local waterways and identify contributing pollution sources within each creek basin.

    Highline School District Agreement to Join Airport Communities Coalition (ACC)

    This 1997 intergovernmental agreement, signed by the Highline School District and several cities in the Sea-Tac Airport vicinity — including Des Moines, Normandy Park, Burien, Federal Way, and Tukwila — establishes a coordinated framework for addressing airport noise impacts and related funding for schools. The agreement supersedes earlier agreements from February 1992 and June 1996 between the same parties. It outlines provisions for settlement authority, dispute resolution, and the role of the Airport Communities Coalition (ACC) Executive Committee in approving any claims or compromises.

Read This!

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.
