    National Pollutant Discharge Elimination System waste discharge permit No. WA-002465-1

    This is a National Pollutant Discharge Elimination System (NPDES) waste discharge permit issued by the Washington State Department of Ecology to the Port of Seattle for SeaTac International Airport, originally effective October 1, 2003. The permit regulates the discharge of industrial wastewater and stormwater into receiving waters including Puget Sound, Des Moines Creek, Miller Creek, Walker Creek, and other local waterways. It sets effluent limits, monitoring requirements, and operational standards for the airport's Industrial Wastewater System to protect water quality in the surrounding region.

    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.

    Annual stormwater monitoring report for Seattle-Tacoma International Airport for the period July 1, 1996 through May 31, 1997

    This 1997 Annual Stormwater Monitoring Report, prepared by Scott Tobiason of Port of Seattle Environmental Services, documents water quality data collected from Seattle-Tacoma International Airport's stormwater discharges between July 1, 1996 and May 31, 1997. The report analyzes discharge samples from stormwater outfalls across the airport's drainage basins, comparing results to regional and national benchmarks, and notes that improvements from newly installed Best Management Practices (BMPs) would be evaluated in the following year's report. It was submitted to the Washington Department of Ecology in fulfillment of Special Condition S.9 of the airport's NPDES permit.

Issues

Sea-Tac Airport is currently undergoing the largest and longest expansion in its history, collectively known as the Sustainable Airport Master Plan (SAMP). Some of it you can already hear, but you’re probably not aware of what it all means. Here’s what you need to know.

As the source for federal transportation grants, the Puget Sound Regional Council was charged with developing a system to meet the growing need for commercial aviation. When the search for a second airport failed, they authorized the Port of Seattle to build the Third Runway, with a mandate to develop a noise abatement and mitigation program. In their effort to stop the Third Runway, the ACC argued over every detail of the Port's efforts--including property buyouts and sound insulation. The dispute was meant to be settled by a three member Expert Arbitration Panel. This is their final report. It finds 2-1, that the Port's program was insufficient in several respects. Despite that, funding for the Third Runway was approved by the PSRC, and the 'Port Package' program, proceeded largely unchanged. Expert Arbitration Panel's final decision finding that the Port of Seattle had not shown sufficient reduction in real on-the-ground noise impacts to satisfy noise reduction conditions required for approval of a third runway at Sea-Tac International Airport. The majority decision concluded the Port's noise abatement programs were insufficient despite being impressive in scope.
