Email dated November 15, 2000 from Chung K. Yee to Kevin Fitzpatrick regarding Sea-Tac fill dirt, specifically the ‘Black’ virgin site where soil samples exceeded Method B 100X groundwater standards under MTCA (Model Toxics Control Act). The site holds 200,000 to 300,000 cubic yards of fill and is workable during winter months. Beth Clark arranged

In a October 2000 letter to the Port of Seattle, Water Resources Consulting LLC — writing on behalf of the Airport Communities Coalition — raised concerns about the SeaTac Aircraft Hydrant Fueling System project, arguing that construction should be delayed until an ongoing groundwater contamination study under the Model Toxics Control Act was completed. The letter criticized the project's environmental review (Declaration of Nonsignificance) for lacking specific details about leak detection, operating pressures, and contaminated soil management. The consultant warned that deep utility trenching could create preferential flow paths for existing fuel contaminant plumes, potentially threatening the groundwater supplies relied upon by nearby communities.

This October 2000 internal memo from Roger Nye to TCP Section Head Steve Alexander explains the history of the Agreed Order between Washington State Ecology and the Port of Seattle regarding environmental cleanup at Sea-Tac Airport. It describes how the Port agreed to conduct a large-scale groundwater evaluation under an Agreed Order, with the understanding that a risk-based cleanup remedy scenario would be developed if contamination risk proved low. The memo also notes that the Agreed Order intentionally excluded language about remedial actions, with Ecology reserving the right to formally intervene if cleanup became necessary.
