In September 2001, the Port of Seattle filed a Notice of Appeal before Washington State's Pollution Control Hearings Board, challenging conditions attached to Ecology's §401 Clean Water Act certification for the construction of a third parallel runway at Seattle-Tacoma International Airport. The appeal document argues that Ecology's certification already fully protects Washington's water resources and that the project had undergone more than a decade of rigorous planning, environmental review, and judicial scrutiny before receiving approval. The filing was prepared by the law firm Foster Pepper & Shefelman and was shared among legal and agency representatives as a confidential, attorney-client privileged communication tied to ongoing settlement discussions.

In September 2001, representatives from the Port of Seattle and the Washington Attorney General's office exchanged emails negotiating the language of Condition E(1)(b), which governs fill material criteria for an embankment construction project. The proposed language would allow the Port to use a 'drainage layer cover' design and to demonstrate fill suitability through Synthetic Precipitation Leaching Procedure (SPLP) testing as an alternative to standard fill limitations. Under the proposal, SPLP test results would be submitted to the Washington Department of Ecology at least ten business days before any fill placement.

This September 2001 draft settlement agreement between the Washington State Department of Ecology and the Port of Seattle addresses the Port's appeal of a Clean Water Act §401 Certification issued for the construction of a third runway at Seattle-Tacoma International Airport. The agreement clarifies and revises several certification conditions related to wetland mitigation, stormwater management, and groundwater monitoring. Both parties agreed to jointly request that the Pollution Control Hearings Board amend the certification accordingly, after which the Port's appeal would be dismissed.

This September 2001 draft settlement agreement between the Washington State Department of Ecology and the Port of Seattle addresses conditions attached to a Clean Water Act §401 Certification for the construction of a third runway at Seattle-Tacoma International Airport. The agreement clarifies and revises specific environmental conditions — including wetland mitigation, stormwater management, and groundwater monitoring requirements — that would remain in effect during and after construction. The Port agreed to file a formal appeal solely to implement the settlement, after which the parties would jointly request the Pollution Control Hearings Board approve the agreed-upon modifications and dismiss the appeal.
