Two 2001 Seattle Post-Intelligencer articles raise safety and environmental concerns about SeaTac Airport's proposed third runway. The first warns that a planned 15-story, 1,450-foot retaining wall built on weak, earthquake-prone soils could catastrophically fail in a seismic event, threatening wetlands and salmon-bearing streams. The second reveals that state officials approved a key water-quality permit for the runway without following their own attorney's advice to secure a water right, prompting the Airport Communities Coalition to appeal the permit and allege political pressure was driving the project forward.

Email chain dated March 12, 2001 from Steve Alexander (ECY/Ecology) to Ann Kenny and Raymond Hellwig, forwarding draft meeting notes from a March 9, 2001 management meeting between the Department of Ecology and the Port Of Seattle regarding the 401 Certification process for Sea-Tac Airport Third Runway. Alexander clarifies that TCP (Toxics Cleanup Program) committed

This internal engineering memo from Jamie Beaver to Mike Bailey, dated March 9, 2001, outlines the process used to determine subgrade improvement zones for a 3R embankment stability project. The analysis focused on liquefaction risks, using post-liquefaction undrained residual shear strength (PLURSS) values derived from seismic reanalysis, ultimately recommending improvement zone widths of 100–120 feet depending on location. The memo notes that factors of safety for the liquefaction and pseudo-static cases generally ranged from 1.0 to 1.2 across various zones.

Memorandum dated March 9, 2001 from Dave Garland, Washington Department of Ecology NWRO Water Quality Nonpoint Unit, to Kevin Fitzpatrick and Ann Kenny, reviewing Earth Tech’s December 2000 ‘Sea-Tac Airport Master Plan Update Low Streamflow Analysis’ (Exhibit 2099, AR 033695–033697). The memo evaluates HSPF streamflow modeling for Miller Creek, Walker Creek, and Des Moines Creek

A March 9, 2001 letter from law firm Helsell Fetterman, representing the Airport Communities Coalition (cities of Burien, Des Moines, Federal Way, Normandy Park, Tukwila, and the Highline School District), demands that Washington State Department of Ecology enforce a 1999 Agreed Order requiring the Port of Seattle to complete groundwater contamination studies at Sea-Tac Airport. The coalition argues that the Port has failed to finish required groundwater flow and contaminant transport studies — originally due December 1999 — and that Ecology cannot legally certify the third runway project under the Clean Water Act without this data. The letter also requests a State Auditor review of how the Port spent grant money provided by Ecology to fund those studies.
