A Port of Seattle publication about construction progress at Sea-Tac Airport

This University of Washington newsletter documents over 50 years of air quality research by the Department of Environmental and Occupational Health Sciences, tracing collaborations with Seattle and regional agencies dating back to 1951. It highlights key studies on particulate air pollution from sources such as car exhaust and burning vegetation in the Pacific Northwest, and describes the work of the EPA-funded Northwest Center for Particulate Air Pollution and Health (PM Center), which operated from 1999 to 2006.

This 1999 newsletter from the Regional Commission on Airport Affairs covers major controversies surrounding Sea-Tac Airport's proposed third runway, including a 31% cost jump bringing construction estimates to $773 million, unresolved wetlands permits requiring the filling of 18+ acres of wetlands and 3,000 linear feet of streams, and disputes over water rights and environmental impacts on local creeks. The newsletter also reports on related issues including a rejected conveyor-belt proposal to transport runway fill, a $500,000 state-funded aquifer study, and separate local disputes over float planes on Seattle's waterfront and helicopter leases at Boeing Field.

This November 1997 environmental update from Washington State's Department of Ecology covers the Sea-Tac Airport third runway expansion project, detailing the FAA's air quality conformity determination, state environmental certification conditions, and required permits. The Port of Seattle was fined for soil erosion violations during construction of an employee parking lot, and was required to implement stormwater controls, groundwater studies, and erosion management plans. Several permits were under active review at the time, including an NPDES stormwater permit and a 404 wetland permit issued by the Army Corps of Engineers.
