This 2003 report by the Puget Sound Clean Air Agency evaluates air toxic chemicals in the Puget Sound region, assessing potential cancer and non-cancer health risks based on air monitoring data and EPA modeling. It identifies priority chemicals of concern, estimates human exposure levels, and draws conclusions about the health impacts of pollutants such as diesel exhaust and woodsmoke on local residents.

Notes

This report presents an evaluation of air toxics in the Puget Sound region, conducted by the Puget Sound Clean Air Agency in conjunction with the Washington State Department of Ecology. The report assesses carcinogenic and non-carcinogenic health risks based on air toxics monitoring data from six sites and modeling from the EPA’s National Air Toxics Assessment (NATA) project. Priority chemicals, uncertainties, and recommendations are identified based on monitoring and modeling results.

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.
