EXH AR023621: Ecology Letter to Kevin Stock re Agreed Order #97TC-N122 401 Certification Third Runway
In this April 11, 2001 letter, Washington State Department of Ecology Director Tom Fitzsimmons responds to attorney Kevin Stock regarding concerns raised by the Airport Communities Coalition (ACC) about the Port of Seattle's proposed Third Runway. Ecology agrees to host a technical meeting with ACC experts to examine whether Third Runway infrastructure could create pathways for contaminants from the Airport Operations and Maintenance Area (AOMA) to proposed runway sites, but declines to halt the 401 water quality certification process pending completion of a separate groundwater study. Ecology assures the ACC that it will not approve or deny the Third Runway projects until a 'pathway' analysis addressing contamination concerns is completed. -

EXH AR025066: Email Stormwater Volume Perspectives Third Runway West Ponds
A 2001 internal email from King County staff puts stormwater storage volumes for the Third Runway project (3RW) into everyday perspective. It compares proposed retention ponds and vaults to familiar landmarks: Pond D would hold the equivalent of over 12 Olympic-size swimming pools, and the largest vault considered (88 acre-feet) would cover a football field with 80 feet of water—roughly an 8-story building. The email also notes that 0.1 cubic feet per second of water flow is equivalent to about five garden hoses running at full pressure. -

EXH AR026684: Site-Specific Water Quality Standard Copper Bioassay Status RP
This 2001 draft report by Parametrix, Inc. describes a water quality study conducted for the Port of Seattle to assess the feasibility of meeting state water quality standards following construction of a third runway at Seattle-Tacoma International Airport. The study focused on developing a site-specific water-effect ratio (WER) for copper in Miller, Walker, and Des Moines Creeks by conducting toxicity bioassays on stormwater samples collected during storm events. The report summarizes results from initial screening and range-finding phases, with the final site-specific water quality standard still pending completion at the time of publication. -

EXH AR023618: Letter Kevin L. Stock (Helsell Fetterman) to Dir. Tom Fitzsimmons (Ecology) Re: 1999 Agreed Order & 401 Certification Process
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. -

EXH AR026298: Ecology Letter to Novadyne Engineering — Regulatory Status Prior Converted Croplands
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. -
