TagPollution Control Hearings Board(1531)

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.

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.

Memorandum dated October 13, 2000 from Michael Bailey P.E. and Michael Kenrick P.E. of Hart Crowser to Jim Thomson P.E. at HNTB (project J-4978-06), analyzing infiltration into the proposed Third Runway embankment at Sea-Tac Airport and effects on shallow water-bearing zone base flow to Miller Creek and adjacent wetlands. Analysis uses three sequential models —

A October 9, 2000 internal memo from Tom Luster to Ecology's SeaTac reviewers outlines a draft list of unresolved issues related to the SeaTac Airport 401 water quality certification review. The issues cover stormwater management, streamflows, wetland impacts, and environmental mitigation plans, including concerns about cumulative impacts on Des Moines Creek and Miller Creek from several interconnected proposed projects. The memo notes that some issues may require only minor document clarifications while others may need significant new documentation or development of formal 401 permit conditions.
