2001-06-07Exhibit 204: Email from Tom Luster re: Sea-Tac NPDES Permit Review, 401 Certification, and Construction BMPs
In this June 2001 internal email, Tom Luster documents a conversation with Ann K. regarding Senator Patterson's request that he review an NPDES stormwater permit related to the Sea-Tac Airport expansion project. Luster notes concerns about whether construction Best Management Practices (BMPs) in the permit were sufficient to meet water quality standards under Section 401 requirements, stating that BMPs with a history of non-compliance should be replaced with proven alternatives. He also addresses his role as an independent reviewer, emphasizing his goal of ensuring a legally defensible decision rather than advocating for any particular party's position.
