This document is a legal declaration by Dr. Peter Willing submitted in support of the Airport Communities Coalition's motion for a stay against the Port of Seattle's water quality certification for construction of a third runway at Sea-Tac Airport. Dr. Willing, a water treatment and water quality expert, argues that the Port's plan to augment low summer stream flows using stored stormwater is an unproven concept lacking necessary design details, manufacturer specifications, or documented precedent.

Dr. John Strand, a fisheries biologist, submitted this declaration to the Washington Pollution Control Hearings Board challenging the state Department of Ecology's water quality certification for Sea-Tac Airport expansion. He argues that stormwater runoff from Seattle-Tacoma International Airport contains copper, lead, and zinc at levels exceeding Washington State Water Quality Criteria, citing the Port of Seattle's own 1995-1996 data showing metals concentrations downstream of airport outfalls far above allowable limits. The declaration was filed in support of the Airport Communities Coalition, representing several cities neighboring the airport, in their motion to stay the certification.
