This August 2001 draft document outlines Water Quality Certification conditions (#1996-4-02325) governing stormwater management at Seattle-Tacoma International Airport (Sea-Tac). It sets requirements for the Port of Seattle to implement and maintain a Comprehensive Stormwater Management Plan, including retrofitting existing impervious surfaces, meeting state water quality standards, and obtaining Ecology approval before discharging stormwater to receiving waters. The document also addresses scheduling, flow control benchmarks, and the use of all known available and reasonable treatment methods (AKART) for runoff from impervious surfaces.

Email chain between John Drabek and Ann Kenny (Washington State Department of Ecology) dated August 3, 2001, regarding a preliminary deliberative draft Section 401 Water Quality Certification (WQC) for the Sea-Tac Airport Third Runway. Drabek raises question about RCW 90.48 required AKART implementation in NPDES permit reissuances and integration with the 401. Kenny’s original email

A declaration by civil engineer William A. Rozeboom, filed with Washington's Pollution Control Hearings Board, raises concerns about the environmental impact of Seattle-Tacoma International Airport's Third Runway construction project. Rozeboom, a stormwater and hydraulics expert retained by the Airport Communities Coalition, warns that the project will reduce low streamflows in Des Moines, Miller, and Walker Creeks during summer months due to increased impervious surfaces and changes to the industrial wastewater system. While the July 2001 Stormwater Management Plan addresses peak flood flows, Rozeboom argues it fails to adequately assess or mitigate the project's impact on low-flow stream conditions.

Sand and Gravel Stormwater Pollution Prevention Plan (SWPPP) prepared by Parametrix, Inc. for Port of Seattle, covering Borrow Areas 3 and 4 of the Third Runway Project at Seattle-Tacoma International Airport. Prepared August 2001, approved by Michael Feldman, Director of Aviation Facilities, Port of Seattle. Document checked by Paul Fendt, P.E. and prepared by Julie

Handwritten notes dated 7/31/01 from Kelly Whiting discuss water quality treatment options for a downstream area, referencing NEPL and CARBO systems with treatment rates of 40% and 10% respectively. The notes cover spill containment and oil management considerations, including gravity oil-water separators and spill containment vaults upstream. A follow-up note from 7/31/01 indicates water quality issues will have comments, with discussion of impact numbers from a 7/23 report.

Letter dated July 31, 2001 from Keith R. Smith, Water Resources Manager at Port Of Seattle, to Ms. Ann E. Kenny at the Washington State Department of Ecology Northwest Regional Office (Bellevue, WA 98008-5452), transmitting conceptual drawings for the proposed Flow Impact Offset Facility at Seattle-Tacoma International Airport. Drawings relate to reserved stormwater release storage,

This July 2001 draft document outlines clean fill criteria for the Port of Seattle's Third Runway construction project at Sea-Tac Airport, requiring the Port to submit environmental assessment documentation to the Washington Department of Ecology before placing any fill material. It specifies that fill may only come from state-certified borrow pits, contractor-certified construction sites, or Port-owned properties, while prohibiting the use of any contaminated or remediated soils. The document details testing and sampling requirements, including review of contamination records and analysis of hazardous substances, to ensure that no toxic materials are introduced into wetlands or state waters during construction.
