Email from Kelly R. Whiting (King County Department of Natural Resources, Water and Land Resource Division, Drainage Services Section) to Rachel McCrea (Floyd & Snider, Inc.), cc Ann Kenny and David Masters, dated March 13, 2001. Whiting provides editorial comments on draft meeting notes from a POS/Ecology 401 permit ‘process and logistics’ meeting held March

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

A March 2001 letter from Water Resources Consulting LLC to the Washington State Department of Ecology raises concerns about a proposed NPDES permit modification for SeaTac Airport, arguing that the draft permit gives the Port of Seattle a 'blank check' to discharge pollutants at unspecified locations into unnamed water bodies without adequate public oversight. The letter also criticizes the airport's stormwater monitoring reports for obscuring potential water quality violations by mishandling hardness data used to evaluate dissolved metals concentrations. The author urges the Department of Ecology to require specific discharge locations and proper concurrent hardness reporting before issuing the modified permit.

Final draft meeting notes from March 9, 2001 (11:00–3:00) for the 401 Permit Decision-Making process for Sea-Tac International Airport Third Runway, prepared by Kate Snider of Floyd & Snider Inc. Attendees included Ray Hellwig, Kevin Fitzpatrick, and Ann Kenny (Dept. of Ecology), Elizabeth Leavitt (Port of Seattle), David Masters (King County), and Floyd & Snider

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.

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.

A March 8, 2001 laboratory report from Columbia Analytical Services sent to John Strand of the Airport Communities Coalition in Richland, WA, presents water quality monitoring results (project 00-101B) from samples submitted on February 20, 2001. The report includes standard data qualifiers and acronym definitions used to interpret inorganic, metals, and organic analytical results. All analyses were conducted under the laboratory's quality assurance program.
