    EXH AR023912: Letter Wingard to Drabek (Ecology) — State Public Disclosure Request Third Runway Construction Monitoring Records

    In a September 21, 2001 fax to John Drabek, Permit Manager at the Washington State Department of Ecology's Northwest Regional Office, Greg Wingard of Smith & Lowney followed up on a delayed State Public Disclosure Request concerning environmental monitoring data from construction activities at the airport. The letter clarifies that documents requested as far back as June 5, 2001—including upstream/downstream construction monitoring records and turbidity discharge data—had not yet been produced, despite being roughly three months overdue. Wingard requested that the documents be made available no later than September 25, 2001, and offered to pick them up in person to avoid further delay.

    EXH AR022903: Sec 401 Cert Synthetic Precipitation Leaching Procedure Work Plan, Attach E — Water Quality Cert #1996-4-02325 (Amended -1)

    This September 2001 Work Plan Attachment describes the fill suitability testing procedures required for the Port of Seattle's third runway embankment construction at Sea-Tac Airport, outlining how soil and fill materials must meet Washington State and U.S. Fish and Wildlife Service environmental standards. It explains the Synthetic Precipitation Leaching Procedure (SPLP), a laboratory test used to determine whether fill materials could release harmful metals or chemicals into groundwater. Materials failing the screening criteria must be rejected or undergo additional testing before being approved for use in the embankment.

    EXH AR026656: BMP Screening Study — Filtration Media Zinc & Toxicity Reduction Stormwater STIA

    Researchers tested several filtration media, including leaf compost (CSF®) and soybean hulls, for their ability to remove zinc and reduce toxicity from stormwater runoff at Seattle-Tacoma International Airport. The study was prompted by prior water quality monitoring that linked stormwater toxicity to zinc from building materials in certain airport drainage areas. Results from these controlled laboratory tests were used to select the best-performing media for future on-site stormwater treatment trials at the airport.

Issues

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.
