In a September 21, 2001 fax to John Drabek, Permit Manager at the Washington State Department of Ecology's Northwest Regional Office, Greg Wingard of Smith & Lowney followed up on a delayed State Public Disclosure Request concerning environmental monitoring data from construction activities at the airport. The letter clarifies that documents requested as far back as June 5, 2001—including upstream/downstream construction monitoring records and turbidity discharge data—had not yet been produced, despite being roughly three months overdue. Wingard requested that the documents be made available no later than September 25, 2001, and offered to pick them up in person to avoid further delay.

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.

The Airport Communities Coalition (ACC) appealed an amended Clean Water Act Section 401 Certification issued by the Washington Department of Ecology on September 21, 2001, related to construction and expansion work at Seattle-Tacoma International Airport. ACC argued that the amended certification weakened already inadequate water quality protections by limiting its scope, reducing wetland monitoring requirements, loosening fill acceptance standards, and bypassing required public notice and comment procedures. The appeal contended that these changes failed to provide reasonable assurance that the airport project would not violate state and federal water quality standards.
