TagThird Runway(1098)

This document examines the geotechnical effects of the February 28, 2001 Nisqually earthquake on earth structures in the Olympia, South Seattle, and Tacoma, Washington area. It covers damage observations including landslides along Highway 101, failures of road and railroad embankments, performance of mechanically stabilized earth retaining walls, and the condition of solid waste landfills following the quake. One notable slide near the State Road 8 junction involved a 15-20 meter high embankment that collapsed and sent debris flowing approximately 150 meters downslope.

This document contains legal discovery materials from a Pollution Control Hearings Board case in Washington State, in which the Airport Communities Coalition (ACC) challenged the Port of Seattle and the Washington Department of Ecology over the Sea-Tac Third Runway Project. The Port of Seattle submitted interrogatories asking ACC to identify its expert witnesses and their prior testimony histories, to which ACC objected as overbroad and burdensome. Expert witnesses from Northwest Hydraulic Consultants, including Bill Rozeboom and Malcolm Leytham, are listed along with their prior cases involving stormwater and water quality issues relevant to the runway project.

This document contains interrogatories and responses from a 2001 Pollution Control Hearings Board case in which the Airport Communities Coalition challenged Washington State Department of Ecology and the Port of Seattle over a Section 401 Water Quality Certification related to Sea-Tac Airport's Third Runway Project. Ecology identified ten expert witnesses, including specialists in water quality certification, wetland mitigation, and stormwater management, who were prepared to testify that the certification's conditions provided reasonable assurance that state water quality standards would be met. The case centered on whether the environmental safeguards imposed on the Third Runway construction adequately protected wetlands and water quality in the surrounding communities.

This legal declaration by Dr. Patrick Lucia, filed in a Washington State Pollution Control Hearings Board case, argues that the Department of Ecology lacks reasonable assurance that fill material used to construct the Sea-Tac Airport Third Runway embankment meets environmental safety standards. Dr. Lucia contends that the certification allows soil concentrations of arsenic and other metals — including cadmium, chromium, lead, mercury, and nickel — that significantly exceed Puget Sound natural background levels. He also criticizes the Port of Seattle's soil sampling approach as arbitrary and unscientific, asserting it fails to meet accepted environmental engineering standards for contaminant testing.
