    EXH AR033731: Email from Tom Luster to Lisa Zinner re 401/Water Quality/Stormwater Issues at Sea-Tac Airport Review

    Email dated October 29, 1998 from Tom Luster to Lisa Zinner (Washington State Department of Ecology) requesting review of a draft 3-page memo summarizing 401/stormwater water quality issues that arose during the SeaTac airport review and a WQ Program/SEA Program meeting. Luster describes it as his ‘401-biased’ view and requests confidential review, asking Zinner not

    EXH AR023654: Draft Internal Email — 401 Water Quality Certs & Stormwater Discharges

    A 1998 internal email from Washington State Department of Ecology staff raises concerns that standard stormwater Best Management Practices (BMPs) may not provide sufficient water quality treatment to meet state and federal Clean Water Act standards for projects requiring 401 Water Quality Certification. The author warns that issuing 401 certifications while knowingly allowing water quality criteria to go unmet would be legally indefensible, and calls for updated policy guidance, better technical assistance, and clearer requirements for applicants. The email proposes that projects involving waters of the state be held to stricter stormwater treatment standards than upland projects not requiring a 401 certification.

Tayloe Washburn of Foster Pepper & Shefelman responding to an August 11, 1998 memorandum requesting clarification and minor revisions to Ecology’s 401 certification (Order No. 96-4-02325) for Sea-Tac Airport improvements including the third runway.

    Exhibit 211: Water Quality Certification and Coastal Zone Consistency Determination, Order #96-4-02325 — Port Of Seattle Master Plan Improvements

    In July 1998, the Washington State Department of Ecology issued a Water Quality Certification and Coastal Zone Consistency Determination (Order #96-4-02325) to the Port of Seattle for construction of a third runway and other improvements at Seattle-Tacoma International Airport. The project would impact between 8 and 12 acres of wetlands, 980 linear feet of Miller Creek, and 2,280 linear feet of unnamed tributaries, requiring mitigation measures including stormwater management enhancements, stream restoration, floodplain improvements, and construction of 16 to 24 acres of replacement wetlands in Auburn, Washington. The certification was granted with specific conditions and penalties for non-compliance, reflecting concerns about environmental damage to local waterways.

    EXH AR024347: EPA Region 10 Letter to Army Corps re Public Notice 96-4-02325 Third Runway Wetlands Fill

    In February 1998, the U.S. EPA Region 10 wrote to the Army Corps of Engineers recommending denial of a permit for the Port of Seattle's proposed third parallel runway at Seattle-Tacoma International Airport, citing concerns over the filling of more than 11 acres of wetlands and portions of Miller Creek and Des Moines Creek. The EPA objected that the applicant's mitigation plan relied almost entirely on off-site wetland replacement in the Green River Valley rather than within the affected watersheds, and questioned whether alternatives to wetland fills for the South Aviation Support Area and on-site borrow areas had been adequately explored. The agency indicated it was willing to work with the Corps and the Port to identify solutions that would satisfy both aviation safety needs and Clean Water Act Section 404(b)(1) requirements.

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.

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.
