  • Port commissioners, keep leaning into a greener future

    By  The Seattle Times editorial board Thanks to the Seattle Port Commission’s leadership, every cruise ship that docks in Elliott Bay must power down their smoke-billowing engines and plug into shoreside electricity by 2027. The new requirement is no idle decree. The tens of millions of dollars the port spent to bring terminal berths the voltage necessary

    Read this, to start understanding the ‘Greener Skies’ fraud

    The 'Greener Skies' program, approved by the FAA in late 2012 and promoted by the FAA and Port of Seattle, promised to dramatically reduce aircraft noise near Sea-Tac Airport by routing more than half of all arrivals over Elliott Bay, far from residential areas. Critics argue the program was fundamentally flawed and never delivered on its promises, as air traffic controllers rarely use the Elliott Bay routes due to the need to merge east- and west-side arrival streams. FAA and industry's own data are cited as evidence that the program amounted to an environmental fraud, with concentrated flight paths continuing to impact west-side communities while east-side routes were never given equivalent precision procedures.

Issues

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.
