This legal document contains the Port of Seattle's responses to interrogatories filed by the Airport Communities Coalition (ACC) before Washington State's Pollution Control Hearings Board. The Port identifies expert witnesses expected to testify on topics including contaminated site cleanup, stormwater quality, wetland mitigation, and environmental review under SEPA and NEPA for Sea-Tac Airport's Master Plan Update projects. The document outlines each expert's anticipated testimony and the basis for their opinions in connection with Clean Water Act permit requirements.

ACC (Airport Communities Coalition) motion for partial summary judgment filed in PCHB No. 01-160 against State of Washington Department of Ecology and Port of Seattle, arguing the Section 401 Certification should be invalidated because the Port lacks a water right to permanently mitigate low-flow impacts of the Sea-Tac Airport third runway project. Cites PCHB December

This document is a deposition of Edward O'Brien, taken on December 21, 2001, as part of a Pollution Control Hearings Board case in Washington State involving the Airport Communities Coalition challenging the Department of Ecology and the Port of Seattle. O'Brien discusses stormwater management techniques, including infiltration facilities, which can be used to treat stormwater quality and mitigate low-flow impacts on surface water systems connected to groundwater. He explains that while infiltration can delay and filter stormwater flows through soil profiles, precise control over timing and flow rates is limited and depends on site-specific soil and hydrological conditions.

This December 2001 letter from the U.S. Fish and Wildlife Service's Western Washington office provides detailed comments on a Monitoring Plan for Embankment Fill Seepage related to a Sea-Tac Airport Master Plan Update, reviewed under the Endangered Species Act. The agency requested key revisions, including monitoring both seepage quality and quantity, beginning monitoring when seepage first occurs rather than after embankment completion, and ensuring groundwater wells are considered as a monitoring pathway. The letter also clarified that any exceedances of water quality criteria must be reported promptly, and that the Federal Aviation Administration—not the Port—would be responsible for reinitiating formal consultation.
