Hart Crowser letter (project J-4978-03) to Barbara Hinkle, Health Safety & Environmental Services, Port Of Seattle, dated December 9, 1998, addressing aquifer compaction beneath the proposed Third Runway embankment at Sea-Tac Airport in response to U.S. Army Corps of Engineers questions on hydrogeologic impacts. Analysis covers the Shallow Aquifer (contributing to Miller Creek base flow),

This December 1998 internal memorandum from Justin Kophs to Linda Logan outlines options for developing a site-specific copper translator for the Port of Seattle, summarizing EPA guidance on dissolved and total recoverable metal sampling studies. It describes recommended approaches including field partitioning studies, historical data equations, and laboratory mixing tests to measure how copper partitions between dissolved and total recoverable forms in receiving water. The memo notes that while a site-specific translator improves compliance measurement accuracy, it cannot be used to influence permit limits in the same way as a Water Effect Ratio (WER).

A 1998 internal memorandum from Washington State's Shorelands and Environmental Assistance Program recommends reclassifying employee Tom Luster from Environmental Specialist 4 to Environmental Specialist 5, citing his assumption of higher-level duties following a colleague's departure in 1997. Luster's qualifications, including a Master's degree in Geography and over 10 years of experience, along with the cost-neutral budget impact, are presented as justification for the upgrade.

This is a catalog of 27 documents acquired by a library or archive in 1998, covering topics related to Seattle-Tacoma International Airport and its surrounding communities. The collection includes environmental reports, noise studies, NPDES water-quality permits, stormwater monitoring data, FAA safety materials, and a third-runway geotechnical study, as well as community-focused documents addressing aircraft noise impacts on local schools and residential areas. Each entry lists the document title, author or agency, original publication date, and the date it was added to the collection.

This Stormwater Pollution Prevention Plan (SWPPP), prepared by the Port of Seattle for Seattle-Tacoma International Airport in November 1998 (with revisions through December 2001), outlines strategies and best management practices (BMPs) to prevent pollutants from contaminating stormwater runoff at Sea-Tac Airport. The plan covers a range of potential pollution sources including aircraft servicing, deicing operations, spills, construction sites, and vehicle maintenance, and describes the airport's drainage systems and inspection requirements under its NPDES permit. It serves as a regulatory compliance document ensuring that airport operations minimize their impact on local water quality.

This November 1998 report presents the Annual Stormwater Monitoring Report for Seattle-Tacoma International Airport, covering the period from June 1, 1997 through June 30, 1998, prepared by the Port of Seattle. It documents stormwater sampling results from various airport subbasins, including measurements of pollutants such as metals, oils, grease, fecal coliforms, and deicing chemicals. The report also evaluates the performance of Best Management Practices (BMPs) implemented across the airport to manage and reduce stormwater contamination.

A 1998 fax from Parametrix, Inc. to the Port of Seattle discusses water quality concerns related to copper in stormwater runoff at Seattle-Tacoma International Airport. The document outlines that while standard Best Management Practices (BMPs) can remove most metals from stormwater, copper remains a persistent challenge due to its widespread presence from sources like automobile brakes and rooftops. It raises questions about compliance requirements, the cost of installing sand or compost filters (potentially up to $100 million), and how the Port and Washington State Department of Ecology can reach a workable agreement on stormwater discharge standards.

In a September 28, 1998 letter from the Port of Seattle to the Washington Department of Ecology, the Port provides a status update on stormwater management efforts at Seattle-Tacoma International Airport, covering detention, treatment, copper loading, and first flush analysis. The letter outlines proposed delivery dates for required reports and explains the complexity of treating stormwater runoff, including challenges related to mandatory FAA-regulated de-icing and anti-icing chemicals used on runways. It also addresses the status of ongoing wetland delineations and water rights reviews connected to the airport's planned third runway construction.

Letter dated September 10, 1998 from Christine O. Gregoire’s Attorney General of Washington Ecology Division (author not individually named) to J. Tayloe Washburn of Foster Pepper & Shefelman responding to an August 11, 1998 memorandum requesting clarification and minor revisions to Ecology’s 401 certification (Order No. 96-4-02325) for Sea-Tac Airport improvements including the third runway.

FAA Northwest Mountain Region letter dated September 2, 1998, from FAA to Brian R. Applebury, Chief Operations Division, Seattle District Corps of Engineers, regarding permit application 96-4-02325 for Port Of Seattle Third Runway at Seattle-Tacoma International Airport. Letter addresses compensatory wetland mitigation, bird/aircraft strike hazard, Advisory Circular AC 150/5200-33 ‘Hazardous Wildlife Attractants on or Near
