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).

Fill Criteria Derivation Chart (Exhibit E) for Third Runway Embankment at Sea-Tac Airport, revised 9-28-01. Charts fill dirt criteria for constituents including antimony, arsenic, barium, beryllium, chromium, copper, lead, mercury, selenium, silver, thallium, diesel, and heavy oils against Ecology criteria, FWS drainage layer cover values, and FINAL drainage layer cover values.

This September 2001 Work Plan Attachment describes the fill suitability testing procedures required for the Port of Seattle's third runway embankment construction at Sea-Tac Airport, outlining how soil and fill materials must meet Washington State and U.S. Fish and Wildlife Service environmental standards. It explains the Synthetic Precipitation Leaching Procedure (SPLP), a laboratory test used to determine whether fill materials could release harmful metals or chemicals into groundwater. Materials failing the screening criteria must be rejected or undergo additional testing before being approved for use in the embankment.

Memo dated September 20, 2001 from Roger Nye, Ecology Toxics Cleanup Program (Northwest Regional Office), to Colleen D. Bradford, Assistant State Auditor, listing eight work product submittals received from Port Of Seattle under Agreed Order #97TC-N122 (finalized May 1999). Submittals span June 1999 through October 2000 and include conceptual hydrogeological flow model presentations, Excel spreadsheet

In September 2001, representatives from the Port of Seattle and the Washington Attorney General's office exchanged emails negotiating the language of Condition E(1)(b), which governs fill material criteria for an embankment construction project. The proposed language would allow the Port to use a 'drainage layer cover' design and to demonstrate fill suitability through Synthetic Precipitation Leaching Procedure (SPLP) testing as an alternative to standard fill limitations. Under the proposal, SPLP test results would be submitted to the Washington Department of Ecology at least ten business days before any fill placement.

Internal email from Ann Kenny (Ecology) to Ching-Pi Wang, cc Steve Alexander (ECY) and Raymond Hellwig, dated August 2, 2001, transmitting deliberative draft Section 401 water quality certification conditions F1–F4 for the Sea-Tac Airport (STIA) Third Runway Master Plan Update. Conditions address prevention of contaminated groundwater transport from the Airport Maintenance and Operations Area via

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.
