Notice of appeal and request for stay pending appeal
The Port of Seattle filed a Notice of Appeal against the Washington State Department of Ecology challenging the terms of a 2003 water discharge permit issued for Seattle-Tacoma International Airport (Sea-Tac). The permit, which governs industrial wastewater and stormwater runoff from airport operations and construction activities, was contested by the Port as imposing undue burdens without corresponding environmental benefits. Over the following six years, the Port faced more than $150 million in projected costs to implement water quality and stormwater control measures under the permit's requirements. -

Chronology of Section 401 permit, second application
This document chronicles the Port of Seattle's second Section 401 Clean Water Act permit application, submitted in September 1999, which was on the verge of being denied by the Washington State Department of Ecology due to multiple shortcomings related to wetlands and water quality. On September 28, 2000, a private, unannounced meeting was held between Port, Ecology, and Governor's office officials, after which the Port strategically withdrew its application to avoid a formal denial. A series of closed-door negotiating sessions followed in October 2000, none of which were publicly announced, raising concerns about political influence and lack of transparency in the permitting process for Sea-Tac Airport expansion. -

Declaration of Dr. Peter Willing in support of ACC’s sur-reply on motion for stay
In this 2001 declaration filed before Washington State's Pollution Control Hearings Board, Dr. Peter Willing challenges the Port of Seattle's commitment to improving stormwater management at Sea-Tac Airport. He argues that the Port's pledge to retrofit its stormwater system 'to the extent practicable' is vague, undefined, and falls short of required water quality standards. Dr. Willing also contends that the four best management practices listed in the Port's Stormwater Master Plan are largely inadequate, as most do not go beyond basic King County water quality requirements. -
