Article by John C. Hall, William T. Hall, and Charles J. Simmons published in Water Environment & Technology (June 1997) arguing that EPA’s 1984 and 1993 copper water quality criteria should not be applied directly to municipal effluents (POTWs) because dissolved copper in biologically treated effluents is complexed with organic and inorganic matter and is

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.

This Superfund guidance document provides soil screening levels (SSLs) and methodologies for evaluating contaminated soil at Superfund sites, including statistical approaches

In a 1996 letter to the Federal Aviation Administration, the U.S. Environmental Protection Agency (EPA) Region 10 raised concerns about air quality impacts from the proposed Master Plan expansion at Seattle-Tacoma International Airport, noting that the project was projected to worsen carbon monoxide levels at nearby intersections in violation of federal air quality standards. The EPA called for a comprehensive emissions inventory, a comparison of air quality with and without the project, and enforceable mitigation measures, while also highlighting inconsistencies in air quality modeling across multiple related development projects in the airport area. The agency urged the FAA and Port of Seattle to coordinate data sharing with regional authorities and establish a long-term air quality monitoring program to address cumulative impacts from surrounding projects.

Executive Order 12898, signed by President Clinton in February 1994, directs all federal agencies to identify and address disproportionately high and adverse environmental and health impacts on minority and low-income populations. It establishes an Interagency Working Group on Environmental Justice, led by the EPA, to coordinate agency strategies, data collection, and research. Each federal agency was required to develop and finalize an environmental justice strategy within 12 months, ensuring that federal programs do not discriminate based on race, color, or national origin.
