A March 16, 1999 outgoing phone call was made to Elizabeth Leavitt of POS regarding her questions about the WER (Work Element Review) outline, review process, and mixing zones. Elizabeth was advised she could discuss the WER outline directly with Kevin Fitzpatrick and Mark Hicks, and that the team was preparing written thoughts on mixing zones for further discussion. The call also addressed scheduling a Port review of the WER workplan outline, with a suggestion to coordinate the review alongside a Fooogy (likely Ecology) meeting the following week.

A 1999 memo from Washington State Department of Ecology staff member Roger Nye to Assistant Attorney General Kathy Gerla raises legal questions about reinstating a full-time 'prepaid' regulatory position at Sea-Tac Airport, funded by the Port of Seattle. The memo outlines the history of the position from 1992–1996, noting it was cancelled due to the lack of a signed Agreed Order, and describes public concerns that the arrangement gave the Port undue influence over Ecology. Key issues flagged include whether the prepaid role can legally extend beyond the scope of an Agreed Order, whether a new Interagency Agreement is needed, and whether reinstatement would require a public comment period likely to draw strong opposition.

This document presents results from a 48-hour acute toxicity test conducted in February 1999 for the Port of Seattle, exposing water fleas (Ceriodaphnia dubia) to copper-contaminated water collected from Miller Creek. The test found that all organisms survived at concentrations up to 50 micrograms per liter, while complete mortality occurred at concentrations of 100 micrograms per liter and above. Water quality parameters including pH, dissolved oxygen, and specific conductivity were monitored throughout the test period.

A February 1999 fact sheet outlining the Joint Transportation Study jointly undertaken by the City of SeaTac and the Port of Seattle under an Interlocal Agreement. The study aims to address ground transportation needs through 2020, covering topics such as population and passenger growth, parking, new transit modes including light rail, neighborhood protection, and pedestrian and bicycle access. It also examines Transportation Demand Management strategies to reduce vehicle traffic around Seattle-Tacoma International Airport.

Draft report (AR 041921) prepared by Parametrix, Inc. for Port Of Seattle, STIA, summarizing procedures and results of acute screening-level Ceriodaphnia dubia bioassays conducted on site water from Seattle-Tacoma International Airport in January 1999. Samples collected January 14, 1999 during a storm event at eight locations including Miller Creek Upstream of Lake Reba, Miller Creek

These are field records from a water quality sampling event conducted on January 14, 1999, at the Miller DS site near McD NC, documenting storm water measurements taken from a culvert. Samplers recorded water levels, flow rates, pH, temperature, and dissolved oxygen at 12 intervals throughout the morning. A flow-weighting calculation worksheet was used to determine subsample volumes, with a total storm flow of 122,400 units recorded from a 4x4.3 pipe.

In January 1999, the King County Superior Court denied the Port of Seattle's motion to dismiss a lawsuit brought by Citizens Against SeaTac Expansion, ruling that a potential injury from wetland filling near the airport could not be ruled out. The case centered on the Port's plan to fill wetlands in Auburn as part of its Master Plan Update, which included construction of a proposed third air carrier runway at Seattle-Tacoma International Airport. The court stayed all further proceedings until the U.S. Army Corps of Engineers issued a final decision on the Port's wetland-filling permit under Section 404 of the Clean Water Act.

In January 1999, the Port of Seattle filed a legal memorandum in King County Superior Court supporting a proposed order to stay (pause) a lawsuit brought by Citizens Against SeaTac Expansion (CASE) regarding the expansion of Seattle-Tacoma International Airport. The central dispute concerned the construction of a proposed third runway and the filling of nearby wetlands, with the Port arguing that court proceedings should be paused until the U.S. Army Corps of Engineers issued a final decision on the Port's wetland-fill permit under Section 404 of the Clean Water Act. The two parties disagreed on the exact language defining how long the stay should last, with the Port seeking a clear end date tied to the Corps' permit decision and CASE proposing broader conditions related to Port environmental decisions.

Port Of Seattle 1999 Airfield Project Soil Fill Acceptance Criteria for STIA airfield projects, describing criteria and review process for acceptance of fill material requested by Washington Department of Ecology in conjunction with 401 Water Quality certification. Covers geotechnical and environmental suitability standards including MTCA Method A contaminant levels, arsenic, TPH and metals analyses. Details

This 1999 Port of Seattle document outlines the criteria and review process for accepting soil fill material used in Sea-Tac International Airport (STIA) airfield construction projects. Fill material must come from approved sources—such as state-certified commercial borrow pits, contractor-certified construction sites, or Port-owned property—and generally must meet Washington State MTCA Method A environmental contamination standards. Contractors and suppliers are required to certify the quality of their materials, and independent soil technicians monitor all deliveries to ensure only safe, suitable fill is placed on airport grounds.
