In the 1930s and 1940s GE designed and manufactured self-propelled, electric passenger railcars that included liquid-cooled transformers. The transformers, which generated a great deal of heat, used a coolant called Pyranol that contains toxic polychlorinated biphenyls (PCBs). GE sold some railcars to government entities whose trains operated on Penn Central lines. Pyranol from the transformers escaped and contaminated four Penn Central rail yards. APU, Penn Central’s successor, had to pay for the costly environmental cleanup and sued GE under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), which makes four classes of “[c]overed persons” strictly liable for environmental contamination, 42 U.S.C. 9607(a). APU argued that GE “arranged for disposal” of hazardous PCB because it designed and manufactured transformers with pressure-release valves whose “natural function” was to discharge Pyranol when conditions required, it knew that “[t]he frequency of minor spills [was] large,” it took affirmative steps to direct spills onto the roadbed; and it implemented a fail-and-fix policy for defective transformers rather than recall them. The Sixth Circuit affirmed summary judgment. GE is neither an arranger nor an operator under CERCLA. APU assigned away its contractual right to indemnification; any claims based on reassigned indemnity rights are time-barred.
