Direct testimony of Chung Ki Yee, Environmental Engineer 3 in the Washington State Department of Ecology Toxics Cleanup Program, submitted before the Pollution Control Hearings Board in PCHB No. 01-160 (Airport Communities Coalition and Citizens Against Sea-Tac Expansion v. Ecology and Port Of Seattle). Yee describes deriving fill criteria for the Port Of Seattle Third

Ecology guidance document (AR017502, Part II of IV) explaining how to use PQL and MDL tables under the Model Toxics Control Act (MTCA). Covers Practical Quantitation Limits (PQLs), Method Detection Limits (MDLs), and comparisons to MTCA Method B cleanup levels for water and soil. Describes analytical methods from US EPA SW-846 (3000, 7000, 8000-8100, 8310,

In December 2001, Hart Crowser, Inc. submitted Washington State Department of Revenue forms to the Department of Ecology certifying an environmental remedial action at a property located at the corner of NE 4th Street and 108th Avenue in Bellevue, King County. The Professional Certification was signed by Matthew F. Schultz, P.E., confirming that the cleanup was conducted independently and in a manner consistent with Washington's Model Toxics Control Act (MTCA). The filing sought a Washington State sales tax exemption and business and occupation tax credit for the environmental remedial action project (J-7600000).

Declaration of Pete Kmet, senior environmental engineer in Ecology’s Toxics Cleanup Program, filed in PCHB No. 01-133 (Airport Communities Coalition v. State of Washington Department of Ecology and Port Of Seattle). Kmet clarifies his June 27, 2001 response to Kevin Fitzpatrick (Water Quality Program) regarding terrestrial ecological risk language for the Clean Water Act §

This 2001 User's Guide from the Washington State Department of Ecology describes software workbook tools (MTCASGL and MTCATPH) designed to help calculate soil and ground water cleanup levels under the Model Toxics Control Act. The guide covers installation, technical requirements, and step-by-step instructions for entering site-specific data such as chemical properties, exposure parameters, and hydrogeological characteristics. Note that while this document addresses environmental cleanup standards, it does not appear to be directly related to Sea-Tac Airport noise policy.

This 2001 User's Guide from the Washington State Department of Ecology explains how to use spreadsheet workbook tools (MTCASGL and MTCATPH) to calculate soil and groundwater cleanup levels under the Model Toxics Control Act. The guide covers how to enter site-specific data—such as chemical properties, exposure parameters, and hydrogeological characteristics—to determine safe contamination thresholds. It is intended for environmental cleanup professionals working on hazardous substance remediation in Washington State.

A July 2001 letter from environmental consultant John Strand raises concerns that the Port of Seattle accepted chemically contaminated soil fill for the proposed third runway at Seattle-Tacoma International Airport. Testing revealed petroleum hydrocarbons (TPH) in soil from Black River Quarry that exceeded cleanup standards, yet the Port transferred the soil to the airport anyway and delayed reporting the results. The letter argues that the Port's Soil Fill Acceptance Criteria are seriously flawed and that approving the project under the Clean Water Act would be ill-advised.

Memo dated June 22, 2001 from Ching-Pi Wang (Toxics Cleanup Program, TCP) to Ann Kenny regarding TCP recommendations for 401 certification related to the proposed Third Runway at Seattle-Tacoma International Airport (STIA). Three recommendations: (1) Port of Seattle to develop a plan by September 14, 2001 to monitor contaminant transport to soil and groundwater via

Internal deliberative email from Chung K. Yee to Kevin Fitzpatrick (cc: Craig E. Thompson, Curtis A. Dahlgren, Tim Nord), dated June 13, 2001, regarding acceptable fill criteria language for the Draft 401 Certification for the Seattle-Tacoma International Airport Third Runway project. Pete Kmet of HQ/TCP recommended MTCA (Model Toxics Control Act) should not be used
