Declaration of Dr. Peter Willing in Support of ACC’s Motion for Stay

Notes

Dr. Peter Willing, an expert in water quality and treatment, declares in support of the Airport Communities Coalition’s motion for a stay regarding the Department of Ecology’s Water Quality Certification No. 1996-4-02325 for construction of a third runway at Sea-Tac Airport. He argues that the Port of Seattle’s plan to augment low summer stream flows with stored stormwater is an unproven concept lacking design details, manufacturer specifications, and substantiation. He further contends that the certification contains defects that fall considerably short of providing reasonable assurance that construction will protect water quality standards.
