Exhibit 2059 (AR 031711–031713, ECY00010776–10778). Email from Gus Ordonez to Ann Kenny dated February 7, 2001, transmitting a memorandum from Jerald LaVassar, M.S., P.E. to Tom Luster reviewing the report ‘Evaluation of Retaining Wall/Slope Alternatives to Reduce Impacts to Miller Creek, Embankment Station 174+00 to 186+00’ for the Third Runway project at Sea-Tac International Airport.

This Washington State Department of Ecology publication, authored by Stewart M. Lombard and Cliff J. Kirchmer and released in February 2001, provides guidelines for preparing Quality Assurance Project Plans (QAPPs) for environmental studies. It outlines standards and procedures to ensure that data collected during environmental investigations meets defined quality and reliability requirements.

Field notes dated 1/28/01 document an inspection of Ace Airport View, recording observations at a stormwater detention station (DM1 - Monitoring Station) near Des Moines Creek. The inspector noted a turbid outfall at SDS-1 in the southwest, associated wetlands, steep sides, and the presence of an oil boom, with water samples collected at 11:45 AM by Dr. Strand. Additional notes reference a southwest pond draining adjacent to the creek, clogging of material at outfall infrastructure, and embankment flows requiring attention to discharge locations.

Memorandum dated January 25, 2001 from Douglas Lindquist (EIT) and Michael Bailey (P.E.) of Hart Crowser, Inc. to the Embankment Technical Review Board (Attn: Pete Douglass), project J-4978-30, CC to Jim Thomson (P.E., HNTB). Provides additional information on seismic analyses for the Third Runway at Seattle-Tacoma International Airport (STIA) in SeaTac, Washington. Covers probabilistic seismic

Letter dated January 25, 2001 from Peter M. Douglass, P.E. (Technical Review Board Facilitator) to U.S. Army Corps of Engineers (Jonathan Freedman, Project Manager) and Washington State Department of Ecology (Ann Kenny, Environmental Specialist) summarizing findings of an independent expert panel convened by Port Of Seattle to review embankment fill and mechanically stabilized earth (MSE)

These are prepared talking points for Washington State Department of Ecology officials attending public meetings on January 26-27, 2001, regarding the proposed Third Runway (3RW) at Seattle-Tacoma International Airport. The notes address 17 anticipated public questions covering topics such as Ecology's 401 Water Quality Certification review process, the use of Port-funded consultants, SEPA compliance, wetlands impacts, and whether the project was receiving special political consideration. Officials emphasized that no approval would be granted until the project demonstrated full compliance with all applicable environmental laws and regulations.

A January 2001 letter and accompanying meeting notes document communications between the Port of Seattle and the Washington Department of Ecology regarding a groundwater contamination study at Seattle-Tacoma International Airport, conducted under the Model Toxics Control Act (MTCA) Agreed Order 97TC-N112. The records outline the scope of the study, which focuses on hydrogeologic investigation and a review of the Fuel Operations Area, and clarify that any necessary cleanup would be handled separately after the study's completion. Both parties discussed concerns about scope expansion and the process for addressing contaminated sites identified through the study.

This document outlines the Washington State Department of Ecology's Section 401 Water Quality Certification review process for the proposed Sea-Tac Airport expansion, detailing the legal standards and unresolved environmental issues involved. Ecology was required to determine whether the expansion would meet state water quality standards by assessing direct, indirect, and cumulative impacts on wetlands, stormwater, and streamflow, while coordinating with federal Clean Water Act permit requirements under Sections 401 and 402. As of October 2000, key aquatic resource protection issues—including stormwater management, wetland mitigation, and streamflow augmentation—remained unresolved pending additional information from the Port of Seattle.

In a January 2001 letter to Washington State Senator Julia Patterson, outgoing Department of Ecology official Tom Luster summarizes the key water quality issues surrounding the proposed Sea-Tac Airport expansion review under Section 401 of the federal Clean Water Act. The assessment outlines concerns including stormwater management, wetland impacts, streamflow, and whether the project's discharges would meet state water quality standards for antidegradation, beneficial uses, and numeric water quality criteria. Luster notes the views are his own and may not fully reflect Ecology's current position, directing the Senator to contact Ann Kenny at Ecology's Northwest Regional Office for the latest information.
