Notes

This document summarizes environmental sampling data from the First Avenue Bridge fill source, including NW-TPH Diesel and Heavy Oil concentrations measured in mg/kg. Samples were collected between October 1999 and May 2000, with additional analyses for RCRA 8 Metals, Lead, and NW-TPH HCID (Gasoline). The table indicates which samples were placed at the Third Runway and notes that materials from samples 1st Ave 21-23 were not placed there per discussions with WSDOT’s Tom Madden.

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.
