TagNPDES(128)

The Washington State Department of Ecology issued this draft addendum to address shortcomings in the NPDES wastewater discharge permit for Seattle-Tacoma International Airport, following a ruling by the Pollution Control Hearings Board. The document outlines required changes to how the Port of Seattle manages contaminated wastewater from aircraft deicing operations, including stricter pollution limits, improved treatment standards, and enhanced water quality monitoring of nearby waterways such as Miller Creek. The revisions focus on reducing harmful biochemical oxygen demand (BOD) discharges into Puget Sound and ensuring the Port implements all available pollution control measures as quickly as possible.

This is a National Pollutant Discharge Elimination System (NPDES) water discharge permit issued by the Washington State Department of Ecology to the Port of Seattle for Seattle-Tacoma International Airport, effective October 1, 2003 through September 4, 2008. The permit governs how the airport is authorized to discharge industrial wastewater and stormwater runoff into surrounding water bodies, including Puget Sound, Des Moines Creek, Miller Creek, and Walker Creek. It sets out special conditions covering discharge limitations, monitoring requirements, toxicity testing, and operations and maintenance standards to protect water quality in the region.

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.

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.

This is a library catalog page listing five legal and regulatory documents from 2003 related to environmental permitting and litigation. The documents include an NPDES water discharge permit (No. WA-002465-1) issued by the Department of Energy, and three entries related to a legal case (ACC v. Colonel Graves) involving a Section 404 appeal and motions for summary judgement filed through the Army Corps of Engineers. A comment letter on the NPDES Draft Permit is also catalogued.

The Washington State Department of Ecology held a public workshop and hearing on March 31, 2003, to discuss the proposed reissuance of a water quality permit for Seattle-Tacoma International Airport. The permit covers industrial wastewater discharges to Puget Sound and stormwater runoff to nearby creeks from airport activities such as aircraft maintenance, fueling, washing, and deicing. Written public comments were accepted through April 15, 2003.

This document is a public responsiveness summary from Washington State's Department of Ecology regarding an NPDES wastewater discharge permit issued to the Port of Seattle for Seattle-Tacoma International Airport. It compiles and responds to comments received during a March 2003 public meeting and hearing, covering concerns about the airport's treated industrial wastewater, stormwater runoff, and construction runoff discharges. The summary addresses feedback from a range of stakeholders, including the Port of Seattle, local legislators, advocacy groups, and individual residents.

This is a library catalog (LBY-2002) listing 16 documents published in 2002 and held in an archive related to Sea-Tac Airport and regional aviation policy. The collection covers topics including airport noise studies, FAA forecasts, wetland mitigation, water quality permits, and legal proceedings involving Section 401 and 404 environmental certifications for the airport. Each entry provides the document title, author or agency, publication date, and the date it was added to the archive.
