These internal deliberative notes from 5/30/00 discuss fill and stormwater management issues related to a construction or development project, covering topics such as soil fill acceptance criteria, Best Management Practices (BMPs) for water quality, spill containment features at Tyee Pond, and monitoring requirements for dissolved metals. The notes reference coordination among multiple regulatory frameworks including Section 401, CZM, and MTCA, and address questions about impervious liner hydrologic impacts and remediation procedures. Key action items include developing an approved stormwater plan, establishing soil sampling protocols for borrow sites, and determining upfront versus incremental BMP implementation strategies.

A December 1999 letter from Port of Seattle Senior Environmental Program Manager Paul W. Agid to the Washington Department of Ecology transmits a 'potential sites' table and map identifying locations at Seattle-Tacoma International Airport where historical operations may have caused soil or groundwater contamination. The document, compiled in compliance with an Agreed Order under Washington's Model Toxics Control Act (MTCA), lists twelve potential sites including former gas stations, fuel tanks, hydrant lines, and maintenance areas. The sites were identified based on past operational activities that had since been discontinued or modified prior to current environmental regulations.

This 1999 internal memo from the Washington State Department of Ecology details the history of environmental cleanup oversight at Seattle-Tacoma International Airport, where 15 separate contaminated sites involving jet fuel and gasoline were managed individually under the state's Model Toxics Control Act. The memo describes a series of prepaid staff positions funded by the Port of Seattle to coordinate cleanup efforts with airline and pipeline companies, and the challenges in getting formal Agreed Orders signed. It concludes with an update that a key groundwater study Agreed Order was finally signed in May 1999 after receiving over 600 public comments in opposition.
