In 1957, Ott Chemical Co. began manufacturing chemicals at a plant near Muskegon, Michigan, and its dumping of hazardous substances polluted the soil and ground water at the site. In 1965, CPC International Inc. incorporated a wholly owned subsidiary, Ott Chemical Co., to buy the assets of the original Ott company in exchange for CPC stock, and the new Ott company continued chemical manufacturing and pollution at the site while sharing officers and directors with CPC, including Arnold Ott.
In 1972, CPC sold Ott II to Story Chemical Company, which operated the plant until its bankruptcy in 1977. The Michigan Department of Natural Resources then examined the site and found thousands of leaking drums and saturated soil and water, prompting negotiations that led Aerojet-General Corp. to arrange transfer of the site in 1977 through its subsidiaries Cordova Chemical Company and Cordova Chemical Company of Michigan, which manufactured chemicals there until 1986.
By 1981, the Environmental Protection Agency had begun planning a long-term cleanup of the site expected to cost tens of millions of dollars. In 1989, the United States filed suit under CERCLA section 107 against CPC, Aerojet, their subsidiaries, and Arnold Ott to recover response costs, following stipulations that the Muskegon plant was a facility, hazardous substances had been released, and the government had incurred reimbursable costs.
After a 15-day bench trial in 1991 on liability issues, the District Court held CPC and Aerojet liable as operators. A divided panel of the Sixth Circuit reversed in part, and on rehearing en banc the court again reversed the District Court in part by a 7-to-6 vote. The Supreme Court granted certiorari in 1997 to address the conflict among circuits regarding parent corporation liability under CERCLA.
