In February 2018, the Department of Justice lodged a proposed consent decree resolving claims against seven defendants, including Northrop Grumman Systems Corporation, for response costs and injunctive relief with respect to the North Sanitary (aka “Valleycrest”) Landfill Superfund Site in Dayton, Ohio. The government alleged the defendants were liable under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) for contamination at the site. The site occupies approximately 104 acres and consists of five former sand and gravel quarries where industrial and municipal wastes were dumped from 1966 to 1989. Northrop Grumman was held liable as the corporate successor to Globe Industries, which owned, possessed, or arranged for the disposal of hazardous substances at the site. Under the settlement, the defendants agreed to “secure financial assurance for the benefit of [the U.S. Environmental Protection Agency], initially in the amount of $33.5 million.”
