Puget Soundkeeper Alliance filed a legal appeal challenging an environmental permit issued to Seattle-Tacoma International Airport (Sea-Tac) by the Washington Department of Ecology in September 2003. The group argued that the airport's National Pollution Discharge Elimination System (NPDES) permit was unlawful because it failed to adequately regulate the discharge of harmful pollutants, including BOD, COD, and toxic substances, into Puget Sound. Key concerns included an overly lenient compliance schedule, the improper approval of a pollution mixing zone, and inadequate monitoring requirements under the federal Clean Water Act and Washington State regulations.Open full document
Notes
Puget Soundkeeper Alliance filed a notice of appeal before the Pollution Control Hearings Board challenging the NPDES Waste Discharge Permit No. WA-002465-1 issued to the Port of Seattle for SeaTac International Airport. The appellant argues the permit is unlawful because it fails to meet requirements of the federal Clean Water Act, allowing unmonitored discharges of BOD, COD, and toxic pollutants into Puget Sound. Specific concerns include an illegally extended AKART compliance schedule, approval of a mixing zone despite lack of AKART implementation, delayed BOD5 monitoring, and inadequate toxic pollutant discharge prohibitions.
