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.

These are the official draft meeting notes from October 13, 2000 negotiations between the Port of Seattle, the Washington Department of Ecology, and King County regarding the 401 Water Quality Permit for Sea-Tac Airport's proposed third runway. The meeting covered technical issues including stormwater management, natural resource mitigation planning, and a master list of permit issues tracked by resolution status. Representatives from multiple agencies worked to resolve outstanding questions about detention sizing, wetland hydrology, and environmental compliance requirements.
