    Air quality status and applicable state implementation plans

    As of 1995, the central Puget Sound region was designated by the EPA as failing to meet federal air quality standards for three pollutants: carbon monoxide, ozone, and particulate matter. The region held 'moderate plus' status for carbon monoxide and 'marginal' status for ozone, with State Implementation Plans (SIPs) submitted to the EPA awaiting approval. Based on improving pollution levels, the region was working toward 'maintenance' status redesignation, with 10-year maintenance plans expected to be submitted to the EPA and approved by 1996.

    Order on Phase I noise issues

    A January 1995 order from Washington State's Puget Sound Regional Council Expert Arbitration Panel addresses noise reduction requirements at Seattle-Tacoma International Airport. The Panel ruled that the Port of Seattle must provide objective, measurable evidence of meaningful real-world noise reductions in surrounding communities by 1996, not merely demonstrate compliance with existing Noise Budget goals or monitoring programs. The Panel also found the Port's proposed Noise Validation Methodology insufficient, citing concerns that the 11 existing remote monitoring stations did not adequately represent the full range of noise experienced by impacted residents.

    Resolution No. EB-94-01: A resolution of the Executive Board of the Puget Sound Regional Council, Seattle, Washington

    ★ 32
    In October 1994, the Puget Sound Regional Council's Executive Board formally approved moving forward with a third runway at Seattle-Tacoma International Airport, concluding that no feasible sites existed for a supplemental airport in the four-county region. The resolution affirmed that the third runway would meet regional air capacity needs through 2030, provided it satisfied noise and demand management conditions and passed environmental review. The Board also recommended that the State develop legislation to compensate communities impacted by essential public facilities and explore long-term transportation alternatives, including high-speed rail.

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.

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.
