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permits, including a Clean Water Act Section 401 certification that was heavily conditioned in 1998 and subsequently withdrawn by the Port.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.
