    EXH AR026637: Trickle Down Effect — Zinc Contamination STIA Stormwater Metal Roofing

    A study at Seattle-Tacoma International Airport found that galvanized metal roofing on cargo buildings was the primary source of elevated zinc levels in the airport's stormwater runoff, which drains into salmon-bearing streams including Miller Creek and Des Moines Creek. Researchers used whole effluent toxicity (WET) testing and source-tracing methods to identify the problem, focusing on one outfall (SDN1) that consistently showed higher zinc concentrations and toxic effects on aquatic organisms. The findings prompted the Port of Seattle to investigate remediation options as part of its stormwater pollution prevention program under its NPDES permit.

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.
