    Exhibit 2127: Email Chain RE: Clean Fill Criteria Language for the 401 Water Quality Certification on the Sea-Tac Third Runway

    Email chain dated September 11, 2000 among Washington State Department of Ecology staff (Chung K. Yee, Kevin Fitzpatrick, Peter Kmet) and ATG’s Joan Marchioro regarding clean fill criteria language for the 401 Water Quality Certification on the Sea-Tac Third Runway. Peter Kmet raises concerns about arsenic limits (proposed 20 vs. background 7-8 in Western Washington),

    EXH AR023947: Third Runway Update Talking Points — ECY SMT Briefing

    This September 2000 internal briefing document from the Washington State Department of Ecology (ECY) outlines the agency's long-running regulatory review of the proposed Third Runway at Seattle-Tacoma International Airport, covering key environmental concerns such as wetland mitigation, stormwater management, and wildlife hazard management. It describes ongoing conflicts with the Port of Seattle over compliance with environmental permits, including a Clean Water Act Section 401 certification that was heavily conditioned in 1998 and subsequently withdrawn by the Port. The document also notes intensifying political pressure from legislators, the Governor's office, and community opposition groups threatening legal action over perceived environmental violations.

    EXH 238A: Northwest Hydraulic Consultants Letter to Ecology — 401 Certification STIA Master Plan Update Stormwater Management Plan Preliminary Review

    A September 7, 2000 letter from Northwest Hydraulic Consultants to the Washington State Department of Ecology raises concerns about the adequacy of the Port of Seattle's Stormwater Management Plan for Sea-Tac Airport's Master Plan expansion. The letter identifies significant technical discrepancies in the plan's analysis of baseflow impacts on Miller Creek, questions the reliability of proposed water-rights acquisitions as mitigation, and flags inconsistencies between the stormwater plan and the Natural Resource Mitigation Plan. The consultants also object to the limited time provided for independent review of the four-volume plan and warn that cumulative water quantity impacts of future commercial development in the airport acquisition area have not been adequately assessed.

    EXH 238: ACC Letter to Ecology — 401 Certification STIA Master Plan Update Preliminary SMP Review Comments

    A September 2000 letter from the Airport Communities Coalition to the Washington State Department of Ecology raises concerns about the adequacy of Seattle-Tacoma International Airport's Stormwater Management Plan submitted for 401 Certification. The letter identifies potential flaws in the analysis of base flow impacts on Miller Creek, inconsistencies between the new plan and earlier natural resource mitigation documents, and concerns about proposed changes to watershed basin boundaries. The authors argue that insufficient time was provided for proper review and that the plan fails to fully account for cumulative water quantity impacts of future development.

    EXH 237: Email Chain Rozeboom to Fitzpatrick — Response Status July 31 Comments STIA 3rd Lagoon Expansion

    This document contains a September 2000 email exchange regarding the proposed expansion of Lagoon #3 in the Sea-Tac Airport Industrial Wastewater System (IWS), in which consultant Bill Rozeboom follows up on unresolved comments submitted to the Washington State Department of Ecology. The attached July 31, 2000 comments raise concerns about discrepancies in the lagoon's design capacity, the risk of frequent overflow into Des Moines Creek, and potential wildlife hazards near aircraft movement areas that may violate FAA guidelines. Additional issues flagged include incomplete construction plans, unaddressed lagoon deficiencies, and the apparent overlap of the lagoon expansion project with 3rd runway construction activities affecting nearby wetlands.

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.
