Email dated November 15, 2000 from Chung K. Yee to Kevin Fitzpatrick regarding Sea-Tac fill dirt, specifically the ‘Black’ virgin site where soil samples exceeded Method B 100X groundwater standards under MTCA (Model Toxics Control Act). The site holds 200,000 to 300,000 cubic yards of fill and is workable during winter months. Beth Clark arranged

A November 2000 letter from the Washington State Department of Ecology to Seattle-Tacoma International Airport summarizes the completion status of environmental tasks required under Agreed Order 97TC-N122. The order mandated a comprehensive groundwater study of the Airport Operations and Maintenance Area (AOMA), including hydrogeological research, contamination mapping, and development of groundwater flow and contaminant transport models. While several research and data-collection tasks were completed, key items such as identifying unknown contamination sources, developing operational groundwater and transport models, and preparing a final Phase I Groundwater Study Report remained incomplete.

A November 2000 memo from Washington State Department of Ecology's Roger Nye raises concerns that the Port of Seattle failed to adequately identify potential soil and groundwater contamination sites at Sea-Tac Airport, as required by an Agreed Order. Nye outlines four key deficiencies, including the Port's failure to account for historical use of chlorinated solvents in aircraft washing, overlooked fueling facilities, and incomplete identification of contamination sources based on historical operations rather than just historical facilities. The memo calls for a thorough, honest effort to identify all potential contamination areas that could pose risks to nearby drinking water wells and surface waters.

Email chain (AR 033715, ECY00000691) between Tom Luster and supervisor Paula Ehlers, dated November 7, 2000, discussing a November 1, 2000 Highline Times article titled ‘Opponents leery as third runway reviewers changed.’ Luster states he was incompletely quoted by reporter Chris Gower regarding his feelings about being reassigned from the third runway review project —

These draft meeting notes from October 27, 2000 document technical negotiations between the Port of Seattle and the Washington State Department of Ecology regarding the 401 Water Quality Permit for Sea-Tac Airport's Third Runway project. The meeting covered key stormwater management topics including detention sizing, base flow impacts, and the Tyee Pond buffer, with participants tracking a master list of technical issues requiring resolution before the permit could be issued. The notes reflect ongoing discussions between agency staff, Port representatives, and engineering consultants to resolve stormwater modeling, hydrology, and environmental compliance questions.

Email dated October 26, 2000 from Chung K. Yee to Kevin Fitzpatrick regarding Sea-Tac Airport fill material contamination concerns. Yee reports a conversation with Paul Agid explaining Ecology and the public’s concerns about possible groundwater and surface water contamination from fill material, and sampling frequency to quantify soil characteristics. Paul Agid expressed interest in discussing

A October 25, 2000 internal memo from Tom Luster to Ann Kenny outlines the transition of the 401 water quality certification review for the Sea-Tac Airport expansion project. It covers key outstanding issues including flow augmentation, water quality BMPs, and Clean Air Act compliance, as well as coordination needs with the Army Corps of Engineers, EPA, and WDFW. The memo also addresses document management, public disclosure requests, and contract administration changes related to the King County Stormwater Review.
