A January 2002 letter from law firm Helsell Fetterman, on behalf of the Airport Communities Coalition, raises concerns with the U.S. Army Corps of Engineers about the Port of Seattle's revised construction plans for the Sea-Tac Third Runway. The Port switched from an in-place ground improvement approach to excavating up to three million cubic yards of material beneath the proposed retaining wall, a major change that critics argue could significantly harm Miller Creek and adjacent wetlands. Attached technical comments from GeoSyntec Consultants also identify deficiencies in the Port's geotechnical report and argue the changes undermine the Port's Clean Water Act Section 404 permit application.

A January 2002 internal email from Washington State Department of Ecology staff raises concerns about elevated levels of metals, particularly lead and arsenic, in fill material being used for the 3rd Runway construction at Sea-Tac Airport. The issue was flagged by the City of Burien as a community sensitivity, with worries that it could become a broader concern for neighboring communities including SeaTac, Normandy Park, and Tukwila. The email seeks clarification on the rationale behind allowable arsenic and lead levels in the runway fill, drawing a comparison to stricter restrictions previously placed on arsenic exports from the Maury Island gravel pit.
