Stormwater Pollution Prevention Plan (SWPPP) for Seattle-Tacoma International Airport (Sea-Tac Airport), prepared by Port Of Seattle, originally November 1998 with Revision 1 (April 1999) and Revision 2 (December 2001). AR 052594. Covers drainage system description, potential pollution sources and Best Management Practices (BMPs) for aircraft servicing, ground anti-icing/deicing of roads and paved surfaces, snow storage,

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.

Draft internal memo dated October 29, 1998 from Tom Luster to Gordon White, Paula Ehlers, and Tom McDonald at Washington State Department of Ecology (Exhibit 2112, AR 033725–033727). Addresses two issues arising from Ecology’s 401 certification review of Sea-Tac Airport (Port of Seattle): (1) whether WAC 173-201A-160(3) water quality standards require stormwater discharges to meet

Email dated October 29, 1998 from Tom Luster to Lisa Zinner (Washington State Department of Ecology) requesting review of a draft 3-page memo summarizing 401/stormwater water quality issues that arose during the SeaTac airport review and a WQ Program/SEA Program meeting. Luster describes it as his ‘401-biased’ view and requests confidential review, asking Zinner not

A 1998 internal email exchange between Washington State environmental officials discusses an urgent regulatory problem that arose during the SeaTac Airport project: stormwater Best Management Practices (BMPs) were found to be inadequate to meet Water Quality Standards, meaning 401 water quality permits could not legally be issued. The Attorney General's office confirmed that 401 permits cannot be granted when stormwater BMPs fail to meet standards at the discharge point, affecting most permit decisions at the time. Officials urged that the issue be added to the agenda of a September 17, 1998 Stormwater Coordination meeting to begin resolving how to handle 401 permits when stormwater concerns arise.

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.

This document maps the Part 150 Noise Monitoring Locations surrounding Seattle-Tacoma International Airport, as prepared by the Port of Seattle in August 1998. It identifies dozens of measurement sites categorized as permanent, semi-permanent, or temporary, spread across communities north and south of the airport including Burien, Des Moines, Normandy Park, Mercer Island, and as far north as the University District. Each site is listed with its specific street address or intersection, providing a detailed geographic record of how aircraft noise was tracked across the wider Seattle-Tacoma region.

This document contains materials from the Seattle-Tacoma International Airport FAR Part 150 Noise Study, including an agenda for a Citizens Advisory Committee meeting held on July 22, 1998, at the airport's Main Terminal Building. The meeting covered topics such as a presentation of Working Paper One on inventory, preliminary noise monitoring results, and an open house discussion. A tentative schedule for follow-up meetings through December 1998 was also included, covering sub-committee sessions and additional CAC/TAC public meetings.
