This August 1994 report, prepared by the Federal Aviation Administration Technical Center in Atlantic City, New Jersey, presents technical data collected as part of the Seattle-Tacoma International Airport Capacity Enhancement Design Team Study. It is the sixth in a series of data packages examining airport capacity and delay simulation at Sea-Tac, with findings subject to revision as the design team's analysis continued. The document serves as an interim reference for planners and researchers studying runway and airspace capacity improvements at the airport.

This March 1994 Final Environmental Impact Statement, prepared jointly by the Federal Aviation Administration's Seattle Airports District Office and the Port of Seattle, evaluates the proposed South Aviation Support Area at Seattle-Tacoma International Airport. The document assesses the potential environmental effects of developing aviation support facilities in the southern portion of the airport, covering impacts such as noise, land use, and related concerns. It was produced as part of the federally required environmental review process before any major airport infrastructure decisions could be approved.

In April 1993, the Puget Sound Regional Council adopted Resolution A-93-03, amending its Regional Airport System Plan to address long-term commercial air transportation needs for the central Puget Sound region. The resolution established a dual-track strategy of pursuing both a major supplemental airport within the four-county area and a third runway at Sea-Tac Airport, with the third runway to be authorized by April 1, 1996 unless a viable supplemental site could eliminate that need. Key conditions attached to the third runway approval included independent evaluation of demand management programs and measurable noise reduction performance objectives, while small supplemental airports such as Paine Field were eliminated as preferred alternatives.

In April 1993, the Puget Sound Regional Council adopted Resolution A-93-03, amending its 1988 Regional Airport System Plan to address long-term commercial air transportation needs in the central Puget Sound region. The resolution established a preferred strategy of pursuing both a major supplemental airport within the four-county area and a third runway at Sea-Tac Airport, with the third runway to be authorized by April 1, 1996 subject to conditions including noise reduction performance objectives and demand management efforts. The resolution also eliminated small supplemental airports such as Paine Field as a preferred alternative and called for site-specific environmental impact studies on the proposed Sea-Tac third runway.

A March 1993 letter from the RCAA (Regional Commission on Airport Affairs) Executive Board addressed to John Sandelius of Seattle, thanking him for his time, energy, and wisdom contributed to the organization's efforts regarding Sea-Tac Airport noise issues. The letter expresses well-wishes for his recovery and notes that his work was valued whenever the community needed him. The document is endorsed by a wide coalition of over 50 community organizations, city governments, and civic groups from the greater Seattle and South King County area opposing airport noise expansion.

The Puget Sound Air Pollution Control Agency (PSAPCA) raised concerns in 1992 about inadequate air quality analysis in the Flight Plan Project's environmental impact statement, citing missing dispersion modeling for both vehicle and aircraft emissions near Sea-Tac Airport. A follow-up 1992 letter addressed the use of ethylene glycol as a de-icing agent at Sea-Tac, concluding it was unlikely to pose a significant air quality risk due to its low vapor pressure. A 1993 internal memo clarified PSAPCA's role in reviewing airport-related environmental impact statements and conducting annual inspections of registered equipment at airports within its jurisdiction.

The Regional Commission on Airport Affairs (RCAA) was a coalition of cities and citizen groups in the Puget Sound region that opposed the proposed third dependent runway at Seattle-Tacoma International Airport in the early 1990s. The organization compiled expert research and white papers covering noise impacts, public health effects, environmental and social consequences, and economic costs associated with airport expansion. Their goal was to identify financially feasible and environmentally responsible alternatives to meet the region's air capacity needs without further expanding Sea-Tac.

This January 1993 document from the Regional Commission on Airport Affairs (RCAA) presents materials to the Puget Sound Regional Council's Transportation Policy and Executive Board covering demand management, airport planning, and regional air capacity alternatives. The packet includes analysis of flight delays, airspace and runway capacity issues, and landside capacity concerns prepared by consultants J. Richard Aramburu and Gerald Bogan, along with alternative airport development ideas from locations such as Grays Harbor County, Toledo-Winlock, and Moses Lake. The RCAA, backed by dozens of community groups and several cities in the Sea-Tac area, sought to offer expert-driven solutions to address long-term aviation capacity needs while addressing aircraft noise concerns affecting surrounding neighborhoods.

This is Book #1 of materials compiled by the Regional Commission on Airport Affairs (RCAA), a coalition of community organizations and cities in the Puget Sound region, submitted to the Transportation Policy Board in January 1993. The packet presents expert reports on air traffic forecasting, economic impacts, noise, effects on children's education, public health, and air pollution—all focused on the proposed expansion of Seattle-Tacoma (Sea-Tac) International Airport. The RCAA argues against airport expansion on the grounds of quality of life, environmental harm, and equity for surrounding communities.

This December 1992 catalog from R.C.A.A. (Residents for Conscious Airport Activity) lists research papers, critiques, and white papers organized by topic—including airport planning, demand and capacity, economics, health, environmental impacts, and noise—all relating to Sea-Tac International Airport expansion. Key concerns addressed include aircraft noise measurement and the adequacy of the 65 Ldn noise metric, air and water pollution from airport expansion, and the evaluation of alternative airport sites. The catalog reflects community and expert opposition to Sea-Tac's third runway proposal and broader regional airport policy decisions in the Puget Sound area.
