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.Open full document
