Internal email chain dated October 23, 2000 from Tom Luster (Ecology) to Raymond Hellwig, Kevin Fitzpatrick, Erik Stockdale, and Joan Marchioro (ATG), forwarded November 20, 2000 to Thomas Fitzsimmons, concerning 401/404 review of SeaTac airport Third Runway expansion. Luster raises unresolved issues including: NPDES major modification and stormwater plan approval for SR-509 interchange as prerequisite

STIA Construction Site Stormwater Monitoring reports dated 10/16/00 and 10/20/00, samplers JL/RS and JB/RS. Documents turbidity and pH measurements at multiple Sea-Tac Airport construction sites including Logistics Site Development (Tyee Pond, Des Moines Creek outfall), MWS Lagoon 3 Construction, Airfield Improvement (SDS3-594, SDS-6, SDS-7), Dobbs Flight Kitchen Remodel (SDE4-611, SDE4-607, SDE4-615, SDE4-601, SDE4-602), Booster Pump

A water resources consultant hired by the Airport Communities Coalition reviewed Sea-Tac Airport's August 2000 Stormwater Master Plan and found it seriously deficient in protecting local water quality. The review concludes that existing pollution controls at the airport are not working, that stormwater discharges regularly violate Washington State Water Quality Standards, and that the Plan's proposed measures fail to provide reasonable assurance that those standards will be met in the future. Key concerns include the diversion of polluted runoff away from local creeks, inadequate handling of metal roof runoff, and the lack of meaningful mass-balance accounting for long-lived pollutants.

This document contains a September 2000 email exchange regarding the proposed expansion of Lagoon #3 in the Sea-Tac Airport Industrial Wastewater System (IWS), in which consultant Bill Rozeboom follows up on unresolved comments submitted to the Washington State Department of Ecology. The attached July 31, 2000 comments raise concerns about discrepancies in the lagoon's design capacity, the risk of frequent overflow into Des Moines Creek, and potential wildlife hazards near aircraft movement areas that may violate FAA guidelines. Additional issues flagged include incomplete construction plans, unaddressed lagoon deficiencies, and the apparent overlap of the lagoon expansion project with 3rd runway construction activities affecting nearby wetlands.
