This December 2001 letter from the U.S. Fish and Wildlife Service's Western Washington office provides detailed comments on a Monitoring Plan for Embankment Fill Seepage related to a Sea-Tac Airport Master Plan Update, reviewed under the Endangered Species Act. The agency requested key revisions, including monitoring both seepage quality and quantity, beginning monitoring when seepage first occurs rather than after embankment completion, and ensuring groundwater wells are considered as a monitoring pathway. The letter also clarified that any exceedances of water quality criteria must be reported promptly, and that the Federal Aviation Administration—not the Port—would be responsible for reinitiating formal consultation.

A December 2001 technical letter from Northwest Hydraulic Consultants, written on behalf of the Airport Communities Coalition, identifies inconsistencies in the Port of Seattle's stormwater management plans for Sea-Tac Airport expansion. The letter argues that the Port's hydrologic modeling failed to account for the planned commercial redevelopment of borrow pit areas by 2006, and that the Natural Resource Mitigation Plan reverted to an outdated stormwater approach relying on regional detention facilities to be built by others. These gaps, the consultants contend, prevent a full assessment of the airport Master Plan Update's environmental impacts.
