United States v. Washington State Department of Transportation – Rains, Drains, and CERCLA Claims

Judge Robert J. Bryan of the United States District Court for the Western District of Washington recently issued two opinions in United States v. Washington State Department of Transportation that could have significant implications on the scope and extent of liability under the Comprehensive, Environmental Response, Compensation, and Liability Act (“CERCLA”), 42 U.S.C. §9601 et seq., particularly at urban river sites and harbors. Both decisions examine the liability of the Washington State Department of Transportation (“WSDOT”) at the Commencement Bay/Nearshore Tidelands Superfund Site.
