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permits, including a Clean Water Act Section 401 certification that was heavily conditioned in 1998 and subsequently withdrawn by the Port.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

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.

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.
