In this March 30, 2001 letter, attorney Kevin L. Stock of Helsell Fetterman writes to Washington State Department of Ecology Director Tom Fitzsimmons on behalf of the Airport Communities Coalition, confirming agreements reached at a March 27 meeting regarding Sea-Tac Airport expansion. The letter asserts that Ecology's 1999 Agreed Order with the Port of Seattle must be fulfilled before a Section 401 water quality certification can legally be issued, and confirms Ecology's commitment to hold a follow-up technical meeting with key staff and legislators present. The ACC argues that strong scientific and legal grounds preclude issuing a defensible 401 certification until the Port completes its obligations under the Agreed Order.

These draft meeting notes from March 28, 2001 document a technical meeting regarding the 401 Permit Decision-Making process for Sea-Tac International Airport's Third Runway project. The meeting covered feedback on stormwater management deliverables, including corrections to hydrological modeling tables and figures, as well as scoping discussions for upcoming deliverables related to vault structural feasibility and maintenance documentation. Representatives from the Department of Ecology, King County, Port of Seattle, and several consulting firms attended, with follow-up meetings scheduled for early April 2001.

A March 28, 2001 letter from the Washington State Department of Ecology clarifies that lands classified as 'prior converted croplands' by the US Army Corps of Engineers are still subject to state wetland regulations if they meet the criteria outlined in the 1996 Washington State Wetland Delineation and Identification Manual. While the federal Food Security Act may exempt such lands from Clean Water Act Section 404 requirements, this exemption does not extend to state law. As a result, some wetlands may be free from federal oversight but remain fully regulated under Washington State rules.

A 2001 internal memo from Parametrix, Inc. summarizes a conversation with the Washington State Department of Ecology (WADOE) about water toxicity testing procedures. The memo reports that WADOE opposes adjusting lab water hardness to match site water, recommending instead that storm water tests target the hardness of the receiving water body, typically 40–60 mg/L as CaCO₃. It also notes that low water hardness (around 10 mg/L) may cause chronic reproductive effects in certain test organisms but not acute toxicity.
