Pollution Control Hearings Board (PCHB) Order Granting Motion to Stay the Effectiveness of Section 401 Certification No. 1996-4-02325 (amended-1), issued by Washington State Department of Ecology to the Port Of Seattle on September 21, 2001, in case PCHB 01-160. Airport Communities Coalition (ACC) filed the motion; Board members Kaleen Cottingham and Robert V. Jensen heard

A December 2001 technical letter from Northwest Hydraulic Consultants, written on behalf of the Airport Communities Coalition, identifies inconsistencies in the Port of Seattle's stormwater management plans for Sea-Tac Airport expansion. The letter argues that the Port's hydrologic modeling failed to account for the planned commercial redevelopment of borrow pit areas by 2006, and that the Natural Resource Mitigation Plan reverted to an outdated stormwater approach relying on regional detention facilities to be built by others. These gaps, the consultants contend, prevent a full assessment of the airport Master Plan Update's environmental impacts.

Agreement effective December 14, 2001 between Port Of Seattle and City of SeaTac for development of Port-owned properties known as Borrow Area #3 (south of South 200th Street, west of 18th Avenue South) and Borrow Area #4 (north of South 200th Street, west and south of 18th Avenue South and South 196th Street). Resolves outstanding

In December 2001, Washington State Department of Ecology drafted a justification to amend its contract with engineering firm Shannon and Wilson, Inc., adding $57,412 to support ongoing review of the Port of Seattle's Natural Resource Mitigation Plan related to the proposed Third Runway project at Sea-Tac Airport. The amendment was needed to cover expert witness testimony before the Pollution Control Hearings Board following an appeal of Ecology's 401 Water Quality Certification, as well as field monitoring of wetland construction and review of revised mitigation documents. Funding for the contract was provided through an interagency agreement with the Port of Seattle and was not approved by the Port Commission until December 11, 2001.

In December 2001, the Port of Seattle submitted a compliance update to the Washington State Department of Ecology documenting fill material placed at the Sea-Tac Airport third runway embankment during October and November 2001. The report lists all fill sources, quantities, and placement locations and elevations for that period, and corrects a calculation error in a previously submitted October summary table. The documentation was prepared to meet the requirements of Condition E of the 401 Water Quality Certification governing the third runway construction project.

This December 2001 report, prepared by Hart Crowser, Inc. for the Port of Seattle, presents baseline chemical characterization results for the Black River Quarry in Renton, Washington, which was evaluated as an off-site borrow source of fill material for the Sea-Tac Third Runway Project. The study involved soil sampling, metals analysis, and data quality review to assess the suitability of quarry material for use in runway construction. Tables and figures detail sample locations, soil descriptions, and total metals analytical results from laboratory testing by North Creek Analytical, Inc.

Memorandum dated December 12, 2001 from Michael Kenrick and Reese Hastings of Hart Crowser Inc. to Jim Thomson of HNTB, project number 4978-62, analyzing pre-construction and post-construction hydrologic conditions at Borrow Area 1 associated with the Port of Seattle Master Plan Update for Sea-Tac International Airport (STIA). Covers surface water and groundwater impacts, wetland hydrology,

In December 2001, Ann Kenny of the Washington Department of Ecology's Northwest Regional Office drafted a memo requesting that hydrogeologist Ching-Pi Wang review a groundwater and seepage monitoring plan submitted by the Port of Seattle for the proposed third runway at Seattle-Tacoma International Airport. The plan, titled 'Third Runway Embankment Seepage and Groundwater Monitoring Plan,' was submitted on November 16, 2001, and required expert review before Ecology could approve it. Wang was asked to provide written comments on the plan's adequacy and any recommended changes by January 18, 2002.
