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.

Email dated October 18, 2000 from Tom Luster (Ecology) to Raymond Hellwig, Paula Ehlers, Kevin Fitzpatrick, and Joan Marchioro (ATG) regarding Sea-Tac Airport Section 401 water quality certification requirements. Luster notes his minority opinion on what the Port of Seattle and Ecology must do to meet 401 requirements, and provides drafty notes from a prior

In an October 18, 2000 email, Tom Luster of Washington State Department of Ecology shares his draft notes from a discussion about what the Port of Seattle and Ecology must do to meet Section 401 water quality certification requirements related to Sea-Tac Airport. Luster acknowledges that his views represent a minority opinion within the group, but argues his written notes may be clearer than his verbal explanations and could help prepare the agency to respond to similar questions likely to arise during public review. He expresses hope that sharing these notes will help the team reach a legally defensible decision on the 401 certification.

In October 2000, Washington State Department of Ecology staff member Tom Luster raised concerns about the adequacy of Ecology's Clean Water Act Section 401 certification review for the proposed Sea-Tac Airport expansion. Luster identified multiple unresolved issues, including insufficient stormwater pollution controls, unevaluated wetland and water quality impacts, and conflicts between Ecology's approach and federal Clean Water Act requirements. He warned that failing to address these issues could result in a legally indefensible permit and degraded water quality in nearby creeks and wetlands.

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.
