Internal email from Ann Kenny (Ecology) to Ching-Pi Wang, cc Steve Alexander (ECY) and Raymond Hellwig, dated August 2, 2001, transmitting deliberative draft Section 401 water quality certification conditions F1–F4 for the Sea-Tac Airport (STIA) Third Runway Master Plan Update. Conditions address prevention of contaminated groundwater transport from the Airport Maintenance and Operations Area via subsurface utility lines, hazardous materials inspection during clearing/grading/construction, contaminant database and mapping updates, and data collection per Model Toxics Control Act (MTCA), Chapter 70.105d RCW. References Port of Seattle ‘Analysis of Preferential Ground Water Flow Paths Relative to Proposed Third Runway,’ dated June 21, 2001. Submission deadline to Ecology Federal Permit Manager, SeaTac Third Runway: September 14, 2001.

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.
