    Air quality status and applicable state implementation plans

    As of 1995, the central Puget Sound region was designated by the EPA as failing to meet federal air quality standards for three pollutants: carbon monoxide, ozone, and particulate matter. The region held 'moderate plus' status for carbon monoxide and 'marginal' status for ozone, with State Implementation Plans (SIPs) submitted to the EPA awaiting approval. Based on improving pollution levels, the region was working toward 'maintenance' status redesignation, with 10-year maintenance plans expected to be submitted to the EPA and approved by 1996.

    Vision 2020, 1995 update: Growth management, economic and transportation strategy for the central Puget Sound region

    Vision 2020: 1995 Update is a growth management, economic, and transportation strategy document produced by the Puget Sound Regional Council for the central Puget Sound region, adopted May 25, 1995. It provides regional policy guidance developed by the Council's Growth Management and Transportation Policy Boards, covering land use and transportation planning for King, Pierce, Snohomish, and Kitsap counties. Funding was provided by member jurisdictions and federal transportation agencies including the Federal Transit Administration and Federal Highway Administration.

    Order on Phase I noise issues

    A January 1995 order from Washington State's Puget Sound Regional Council Expert Arbitration Panel addresses noise reduction requirements at Seattle-Tacoma International Airport. The Panel ruled that the Port of Seattle must provide objective, measurable evidence of meaningful real-world noise reductions in surrounding communities by 1996, not merely demonstrate compliance with existing Noise Budget goals or monitoring programs. The Panel also found the Port's proposed Noise Validation Methodology insufficient, citing concerns that the 11 existing remote monitoring stations did not adequately represent the full range of noise experienced by impacted residents.

    Resolution EB-94-01 adopted October 27, 1994 by the Puget Sound Regional Council (PSRC) Executive Board, affirming the General Assembly’s Resolution A-93-03 approving a third all-weather runway at Sea-Tac International Airport.

    Twelve Sites Identified as Potential Supplemental Airports

    In May 1994, the Puget Sound Regional Council announced that consultants had identified 12 potential sites for a major supplemental airport in the central Puget Sound region, narrowed down from an initial list of 25 candidates. The sites, stretching from Stanwood in the north to the Tanwax Lake area in Pierce County in the south, were deemed to have no flaws severe enough to rule them out from further consideration. The study was part of a broader effort to determine whether a supplemental airport could relieve pressure on Sea-Tac and potentially eliminate the need for a controversial third runway.

    Resolution A-93-03: A resolution of the General Assembly of the Puget Sound Regional Council amending the 1988 Interim Regional Airport System Plan (RASP) for long-term commercial air transportation capacity needs of the region

    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.

    Puget Sound Regional Council amends the Regional Airport System Plan to support a third runway at Sea-Tac International Airport

    On April 29, 1993, the Puget Sound Regional Council’s General Assembly adopts Resolution A-93-03 amending the 1988 Regional Airport System Plan  (RASP) on the basis of a three-year “Flight Plan” study concluded in 1992. The Resolution declares that “the region should pursue vigorously, as the preferred alternative, a major supplemental airport and a third runway

    Flight Plan Project: Materials distributed at the Flight Plan workshops for the Regional Council’s Transportation Policy Board and Executive Board

    This collection contains materials from the Flight Plan Project workshops held in January and February 1993, organized for the Regional Council's Transportation Policy Board and Executive Board to address airport planning and capacity needs in the Puget Sound region. The binders include working papers, overhead presentations, environmental impact statement documents, public hearing records, and correspondence from stakeholders ranging from the FAA and Port of Seattle to community groups opposing airport expansion. Key topics covered include demand management, noise abatement, regional airport system alternatives, and the evaluation of sites such as Sea-Tac and Paine Field.

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.

Read This!

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.
