    Miller and Walker Creeks Basin Plan appendices

    The Miller and Walker Creeks Basin Plan Appendices, published in February 2006, is a regional watershed management document developed collaboratively by King County, the City of Burien, the City of SeaTac, the City of Normandy Park, the Port of Seattle, and the Washington State Department of Transportation. The plan addresses stormwater, habitat, and water quality issues within the Miller and Walker Creek drainage basins located near the Sea-Tac Airport area. It provides technical appendices to support basin-wide strategies for managing creek health and flood-related impacts in this urbanized watershed.

    SeaTac City Council regular meeting agenda and minutes, October 11, 2005

    This document contains the agenda and minutes from the SeaTac City Council Regular Meeting held on October 11, 2005, covering routine municipal business such as approval of financial vouchers, council meeting minutes, and several interlocal agreements. A notable agenda item was a presentation by King County Councilmember Julia Patterson and community partners requesting the City of SeaTac invest matching funds in a proposed school-linked health clinic at Tyee High School. Note that this document does not address SeaTac Airport noise policy; it focuses on general city governance and community health initiatives.

    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.

    Port, Des Moines work together on business park plan

    In June 2005, the Port of Seattle and the city of Des Moines — formerly legal adversaries over Sea-Tac Airport's third runway — unanimously agreed to collaborate on a proposed 75-acre Des Moines Creek Business Park on land south of the airport that was cleared of homes in the late 1980s as part of a noise mitigation program. Studies suggested the site was best suited for aviation-related or general industry, with potential uses including manufacturing, distribution, and retail. The partnership marked a significant shift in relations between the two parties, with construction potentially targeted for early 2007 pending approval of a conceptual master plan in early 2006.

    Addendum to fact sheet: Port Of Seattle Sea-Tac International Airport NPDES Permit No. WA-002465-1

    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.

    Notice of appeal – Airport Communities Coalition v. State of Washington, Department of Ecology, and Port Of Seattle

    The Airport Communities Coalition (ACC) — representing the cities of Burien, Des Moines, Federal Way, Normandy Park, Tukwila, and the Highline School District — filed a formal appeal challenging Washington State's 2004 Clean Water Act certification for the Port of Seattle's proposed third runway at Seattle-Tacoma International Airport. The coalition argued that the certification violated Supreme Court mandates and water quality laws by allowing contaminated fill material to be used in construction, threatening nearby streams and wetlands. The appeal was submitted to the Pollution Control Hearings Board for the State of Washington.

    Letter to Peter Eglick re ACC v. Graves, et al., No. 04-35011 (9th Cir.)

    In a May 26, 2004 letter, Port of Seattle Senior Counsel Traci M. Goodwin notified attorney Peter Eglick that the Port planned to begin construction of a third runway at Sea-Tac Airport on or before June 7, 2004, following a Washington State Supreme Court ruling affirming Ecology's Clean Water Act certification. The letter references the case ACC v. Graves (9th Cir. No. 04-35011) and warns opposing counsel of the Port's construction timeline under Ninth Circuit Rule 27-3, which requires advance notice when a party may seek emergency relief within 21 days.

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.
