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.

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.

Materials failing the screening criteria must be rejected or undergo additional testing before being approved for use in the embankment.
