A May 2001 letter from the Port of Seattle's Environmental Program Manager to the Washington Department of Ecology provides a quarterly update on fill material placed at the Sea-Tac Airport Third Runway Embankment project. The letter presents final tonnage and calculated volumes of soil placed during the Phase III Embankment contract (May 2000 through February 2001), noting no new fill sources were received in the first quarter of 2001. An attached summary table lists all fill sources, suppliers, categories, and final volumes consistent with the 1999 Airfield Project Soil Fill Acceptance Criteria.

An independent wetland scientist, writing on behalf of the Airport Communities Coalition, raised concerns with the US Army Corps of Engineers about potential mapping errors affecting Wetland 44a near the proposed SR509 Temporary Interchange for Sea-Tac Airport's Third Runway project. The letter warned that discrepancies between engineering drawings and actual field conditions could mean the wetland was closer to the construction zone than documented, risking illegal filling or sediment discharge into protected wetlands. The scientist urged the Corps to verify the wetland's true location and review erosion control measures before approving any construction permits.
