Exhibit AR 026670: Static Acute Ceriodaphnia dubia Toxicity Test — Copper in Miller Creek Site Water, Port Of Seattle

Notes

Static acute Ceriodaphnia dubia toxicity test (Test Number 2183) conducted by Parametrix Toxicology Laboratory for Port Of Seattle, sample collected 2/22/99, test dates 2/23/99 through 2/25/99. Test material is copper (Cu) in Miller Creek site water (CUSW), source WA0024651, concentrations ranging from 0 to 200 µg/L. Results show 100% survival at concentrations up to 50 µg/L and 0% survival (complete mortality) at 100, 150, and 200 µg/L. Water quality parameters including pH, dissolved oxygen, and specific conductivity recorded. Documents AR 026670, AR 026671, AR 026672. Water flea (Daphnia) acute 48-hour bioassay. Miller Creek copper contamination toxicity.

Sidebar On/Off

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.
