A March 15, 2001 laboratory report from Columbia Analytical Services sent to John Strand of the Airport Communities Coalition, summarizing water quality test results from samples submitted on February 28, 2001. The report, assigned service request number K2101434, confirms all analyses were conducted under the laboratory's quality assurance program. It includes reference sheets defining technical acronyms and data qualifiers used in interpreting inorganic, metals, and organic test results.

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.

In March 2001, GeoSyntec Consultants submitted a correction to a technical review letter concerning the Third Runway Project at Seattle-Tacoma International Airport, clarifying that the seismic stability analysis used by Hart Crowser may seriously overestimate—not underestimate—the wall's ability to withstand earthquake loads. The firm argued that analyzing only the failure surface with the lowest static safety factor, rather than independently searching for the critical seismic failure surface, is an incorrect methodology. GeoSyntec recommended a proper pseudo-static slope stability analysis to ensure adequate ground improvement measures are applied in the right areas.

In a March 2001 email exchange, Paul Fendt responds to Ken Ludwa regarding specific information requests related to TESC (Temporary Erosion and Sediment Control) facilities, calling the level of detail requested 'absurd.' The information requests from Ludwa included clearing limits, tributary areas for ESC facilities, pump sizes, power supply specifications, spill prevention plans, and the expected duration of temporary facilities. The document appears to be part of an administrative record related to construction or environmental control planning at or near Sea-Tac Airport.

A February 2001 laboratory report from Columbia Analytical Services transmits water and sediment quality monitoring results to Columbia Biological Assessments in Richland, Washington, under service request K2101038. The report confirms that all analyses were conducted in accordance with the laboratory's quality assurance program, with samples received on February 12, 2001 and preliminary results faxed on February 23, 2001. The accompanying documentation includes standard data qualifier codes for inorganic, metals, and organic results used to interpret analytical findings.

This February 2001 report by Herrera Environmental Consultants presents a five-year summary of water quality monitoring conducted for the City of Des Moines, Washington, covering three creek basins: Des Moines Creek, Massey Creek, and North Fork McSorley Creek. The report examines a range of water quality parameters including temperature, pH, dissolved oxygen, metals, nutrients, turbidity, and fecal coliform bacteria, as well as benthic invertebrate conditions as indicators of stream health. It was prepared for the City's Surface Water Management Utility and provides data intended to inform stormwater and surface water management decisions in the Des Moines area near Sea-Tac Airport.

A February 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), urges the U.S. Army Corps of Engineers and Washington State Department of Ecology to deny the Port of Seattle's permits for the proposed Sea-Tac third runway. The letter argues that the Port had already spent nearly $300 million on construction before receiving required Clean Water Act approvals, and that its application lacked adequate stormwater management plans and failed to meet water quality standards. Independent experts retained by the coalition found the Port's environmental mitigation proposals to be technically flawed, incomplete, and legally insufficient.

Handwritten notes from an Ecology informational meeting with Erik and Ann dated February 14, 2001 (AR 018355-018357). Topics include stormwater plan analysis from Kelly Whiting and John Drybeck (water quality staff), Vasen Farm farmed wetland ratios (1:1 in-basin acreage, 2:1 out-of-basin replacement), enforcement vs. restoration, prior converted designation, Corps of Engineers wetland determinations, 509 overpass,
