    Executive order 13045 protection of children from environmental health risks and safety risks

    Executive Order 13045, signed by President Clinton in April 1997, directs federal agencies to identify and address environmental health and safety risks that disproportionately affect children, recognizing that children are more vulnerable due to their developing bodies and behaviors. The order establishes a Task Force co-chaired by the Secretary of Health and Human Services and the EPA Administrator to coordinate federal research and recommend protective strategies. It also requires agencies to evaluate the effects of significant regulations on children's health and safety before those rules take effect.

    Memorandum of Agreement: Air Quality Monitoring Program Activities Relating to the Seattle-Tacoma International Airport Vicinity

    This 1996 Memorandum of Agreement establishes a 24-month air quality monitoring program near Seattle-Tacoma International Airport, involving the Port of Seattle, FAA, EPA, Washington State Department of Ecology, and the Puget Sound Air Pollution Control Agency. The program, funded at $195,000, focuses on measuring carbon monoxide, nitrogen oxides, and aircraft fuel particle residue to establish baseline air quality data and evaluate potential pollution impacts from planned airport expansion projects. The Port agreed not to proceed with expansion elements projected to cause carbon monoxide standard violations until monitoring is complete and, if necessary, mitigation measures are identified.

    Public health and welfare criteria for noise

    This 1973 U.S. Environmental Protection Agency document establishes scientific criteria for understanding how noise affects public health and welfare, including hearing damage, annoyance, communication interference, and property value loss. Prepared by EPA's Office of Noise Abatement and Control under the Noise Control Act of 1972, it describes cause-and-effect relationships between noise exposure and human health impacts. The criteria laid out in this document were intended to serve as a foundation for developing future noise standards and regulations, though the document itself does not constitute a standard or regulation.

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.
