Letter to Ed Abbasi regarding unified position on NPDES permit modification for Seattle-Tacoma International Airport
In August 2005, the Port of Seattle and Citizens Against SeaTac Expansion (CASE) jointly wrote to the Washington Department of Ecology presenting a unified position on proposed changes to the NPDES wastewater permit for Seattle-Tacoma International Airport. The two parties collaborated to resolve disputed permit conditions — covering issues such as BOD discharge limits and pipeline compliance schedules — and categorized each comment as requiring a permit change, a response only, withdrawal, or unresolved. Both parties agreed not to appeal any permit modifications that fell within the mutually agreed categories, aiming to avoid litigation while achieving a workable final permit. -

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. -
