    EXH AR023656: Memo Nye to Alexander — Changing Scope Agreed Order, Cleanup Actions or CAP

    This October 2000 internal memo from Roger Nye to TCP Section Head Steve Alexander explains the history of the Agreed Order between Washington State Ecology and the Port of Seattle regarding environmental cleanup at Sea-Tac Airport. It describes how the Port agreed to conduct a large-scale groundwater evaluation under an Agreed Order, with the understanding that a risk-based cleanup remedy scenario would be developed if contamination risk proved low. The memo also notes that the Agreed Order intentionally excluded language about remedial actions, with Ecology reserving the right to formally intervene if cleanup became necessary.

Sea-Tac Airport is currently undergoing the largest and longest expansion in its history, collectively known as the Sustainable Airport Master Plan (SAMP). Some of it you can already hear, but you’re probably not aware of what it all means. Here’s what you need to know.

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.
