This King County map, dated December 8, 2003, identifies Potential Water Quality Regulatory Areas within the Walker Creek Basin, highlighting features such as streams, lakes and ponds, wetlands, potentially regulated parcels, and potentially regulated roads. The map was compiled by King County staff to support water quality planning and regulation in the basin. Note that while this document relates to King County environmental planning, it does not directly address Sea-Tac Airport noise policy.

A 2003 newsletter from the Regional Commission on Airport Affairs (RCAA) criticizes the Port of Seattle for claiming credit on aircraft noise reduction at Sea-Tac Airport without actually implementing the key recommendations—such as building a hush house for engine run-up noise—that its own Part 150 community committee proposed. The newsletter also highlights the Port's contradictory positions, including claiming the Third Runway would boost economic capacity while simultaneously arguing it would add no new flights and therefore require no noise mitigation. Critics argue these tactics allowed the Port to satisfy regional planning requirements on paper while avoiding real environmental costs.

A public meeting was held on October 2, 2003, at the Washington State Criminal Justice Training Center in Burien, WA, to discuss the Miller, Walker, and Salmon Creek Basin Planning Project. The meeting covered basin problems and potential solutions, and included an open house, a presentation, and a Q&A session. The project was overseen by a management team representing the City of Burien, City of SeaTac, Port of Seattle, King County, City of Normandy Park, and the Washington State Department of Transportation.

This King County map document depicts the Miller Creek Basin, covering portions of the incorporated cities of Burien, Normandy Park, and SeaTac, as well as surrounding unincorporated areas. It highlights key waterways including Miller Creek, Walker Creek, and the Duwamish River, along with lakes, wetlands, and notable drainage features such as the Hermes Depression and SW 142nd Street Depression. The map was produced by the King County Water and Land Resources Division and includes river mile markers and jurisdictional boundaries relevant to watershed and land-use planning in the vicinity of Seattle-Tacoma International Airport.

This King County Water and Land Resources Division map document depicts the Walker Creek Basin, a watershed area located near Sea-Tac Airport encompassing portions of the incorporated cities of Burien, Normandy Park, SeaTac, and Des Moines in Washington State. The map identifies key waterways including Walker Creek, Miller Creek, and Des Moines Creek, along with wetlands, lakes, and river mile markers within the basin boundary. Created in 2003, it serves as a geographic reference for water resource and land use planning in this urbanized watershed area.

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.

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.

Environmental groups challenged the validity of Seattle-Tacoma International Airport's wastewater discharge permit, arguing that it failed to require the Port of Seattle to use all known and reasonable methods to treat pollution from aircraft deicing fluids. The permit allowed largely untreated industrial wastewater containing high levels of biochemical oxygen demand (BOD) from glycol-based deicing chemicals to be discharged into Puget Sound, despite the Port's own recommendation for full biological treatment. The groups sought a ruling to invalidate the permit and force regulators to reissue it in compliance with state and federal environmental law.
