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.

In a December 1998 ruling, King County Superior Court Judge Peter D. Jarvis denied the Port of Seattle's motion to dismiss a lawsuit filed by Citizens Against SeaTac Expansion, finding that the group had legal standing to challenge the Port's environmental decision regarding replacement wetlands in Auburn. The court determined that this decision was interrelated to the broader Seattle-Tacoma International Airport Master Plan Update, including the proposed Third Runway. While rejecting dismissal, the court stayed all proceedings until the Port completed all required environmental reviews under SEPA and Sections 401 and 404 of the Clean Water Act.

In this 1998 court declaration, Lawrence Corvari, Co-President of Citizens Against SeaTac Expansion (CASE), challenges the Port of Seattle's Auburn Mitigation Plan and its environmental review determination. Corvari argues that building replacement wetlands in Auburn rather than near the affected Miller Creek or Des Moines Creek watersheds leaves adverse environmental impacts unmitigated, harming CASE members' ability to enjoy local wildlife and a healthy environment. The declaration also corrects what Corvari describes as misrepresentations of his deposition testimony by the Port's attorneys in their Motion to Dismiss for Lack of Standing.
