    Focus on: Improving Air Quality in Overburdened Communities

    Washington State's Department of Ecology has identified 16 overburdened communities across the state that are highly impacted by criteria air pollution, collectively representing over 1.2 million residents. Using air quality data and environmental justice tools, the agency is working under the Climate Commitment Act to reduce six key pollutants — including particle pollution, ozone, and nitrogen dioxide — in areas ranging from South Seattle and South King County to rural communities like Mattawa and the Lower Yakima Valley. Next steps include expanding air monitoring, engaging affected communities, and working with Tribal governments to address pollution impacts over multiple years.

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.
