Pre-filed direct testimony of Paul S. Fendt, P.E., submitted to the Pollution Control Hearings Board (PCHB), case No. PCHB 01-160, Airport Communities Coalition (ACC) and Citizens Against Sea-Tac Expansion (CASE) v. Department of Ecology and Port Of Seattle. AR 016335. Testimony covers stormwater impacts from the MPU (Master Plan Update) improvements at Sea-Tac Airport, including

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.

Pre-filed testimony of Dyanne Sheldon, environmental scientist and wetland ecologist, submitted on behalf of appellant Airport Communities Coalition (ACC) in PCHB No. 01-160, ACC & CASE v. Dept. of Ecology & Port of Seattle, dated February 22, 2002. Testimony addresses discrepancies in Ecology’s regulatory authority over wetlands, restoration/creation credits, wetland function assessment, 401 permit conditions,

Feldman, Director of Aviation

Water quality criteria spreadsheet (CRITERIA.XLS) for the SeaTac Third Runway Embankment Project, prepared by Chung Ki Yee, run date 2/20/02, created by D. Nunnallee (rev. 1-92) with last revision 3/00. Lists fresh and marine acute and chronic water quality criteria (in ug/L) for metals including antimony (inorganic), arsenic (dissolved), beryllium, cadmium, chromium (TRI and HEX),

This legal document is a supplemental response filed by the Airport Communities Coalition (ACC) in a Washington State Pollution Control Hearings Board case (No. 01-160) against the State Department of Ecology and the Port of Seattle. It lists scientific references and studies relied upon by ACC's expert witnesses, covering topics such as the effects of airport deicing chemicals on water quality, dissolved oxygen levels in receiving streams, fluoride impacts on salmon, and toxicity of stormwater runoff to aquatic life near Seattle-Tacoma International Airport.

This document is an agenda for a Low Streamflow Analysis Meeting held on February 19, 2002, at the Department of Ecology in Bellevue, Washington. The meeting covered technical modeling and water flow topics for three local waterways — Walker Creek, Miller Creek, and Des Moines Creek — including reviews of land cover tables, groundwater routing, and calibration. General topics such as water quality monitoring, channel hydraulics, and embankment modeling were also on the agenda.

Dr. John Strand, a fisheries biologist with over 25 years of experience, submitted this declaration in support of the Airport Communities Coalition's legal challenge to Washington State's water quality certification for Sea-Tac Airport's third runway expansion. Drawing on his own water quality sampling of Miller and Des Moines Creeks in 2000, Dr. Strand argues that the certification fails to adequately protect sensitive local waterways from stormwater runoff containing heavy metals, petroleum hydrocarbons, and other contaminants. He urges the Pollution Control Hearings Board to stay the certification until Clean Water Act compliance questions are fully resolved.

In February 2002, Washington State Department of Ecology staff exchanged emails about resource constraints in reviewing the Port of Seattle's Low Streamflow Report related to Sea-Tac Airport's Third Runway project. Water Quality section chief Kevin Fitzpatrick warned that his team's resources were stretched to a breaking point and that senior staff could no longer participate in low flow analysis, leaving Ed Abbasi and John Drabek as primary contacts. Senior Regional Planner Ann Kenny explored options to offset costs, including billing staff time to an Interlocal Agreement with the Port and potentially contracting with the EPA for technical assistance.
