    Exhibit 205: Tom Luster Notes on Call with Ann Kenny re 401/Agreed Order/Governor’s Certification Letter

    In a June 2001 internal memo, Tom Luster notes a call from Ann Kenny of the Washington Department of Ecology regarding the Sea-Tac Airport third runway project. Kenny indicated that Ecology intended to separate the Section 401 water quality certification from the Agreed Order, planning a new study to examine possible contamination pathways from the Airport Operations and Maintenance Area (AOMA) to the third runway site. Luster noted that if called upon for an affidavit, his testimony would reflect his understanding of how the key documents were connected during his time as project reviewer.

    EXH AR019469: NMFS Biological Opinion — STIA Master Plan Update, ESA Section 7 & Essential Fish Habitat

    In May 2001, the National Marine Fisheries Service (NMFS) issued a biological opinion concluding that planned construction and expansion projects at Seattle-Tacoma International Airport — including a new 8,500-foot runway and other facility upgrades — were not likely to adversely affect threatened Puget Sound chinook salmon or their designated critical habitat. The review, requested by the FAA under the Endangered Species Act, examined potential impacts to nearby waterways such as Miller, Des Moines, and Gilliam creeks, as well as Essential Fish Habitat for coastal and groundfish species. NMFS concurred with the airport's own Biological Assessment, determining the projects could proceed with the mitigation measures proposed.

    EXH AR026298: Ecology Letter to Novadyne Engineering — Regulatory Status Prior Converted Croplands

    A March 28, 2001 letter from the Washington State Department of Ecology clarifies that lands classified as 'prior converted croplands' by the US Army Corps of Engineers are still subject to state wetland regulations if they meet the criteria outlined in the 1996 Washington State Wetland Delineation and Identification Manual. While the federal Food Security Act may exempt such lands from Clean Water Act Section 404 requirements, this exemption does not extend to state law. As a result, some wetlands may be free from federal oversight but remain fully regulated under Washington State rules.

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.
