Before World War II, Japanese Admiral Yamamoto wrote: “Because I have seen the motor industry in Detroit and the oilfields of Texas, I know Japan has no chance if she goes to war with America, or if she starts to compete in building warships.” As he anticipated, after hostilities broke out the United States government quickly began to mobilize the nation’s considerable natural resources and manufacturing capacity.
The War Production Board (WPB) was established in 1942 in order to "increase, accelerate, and regulate the production and supply of materials, articles and equipment and the provision of emergency plant facilities . . . required for the national defense." The WPB and similar entities had the ability to determine how various raw materials would be used, set prices, and enter into novel contractual arrangements with defense contractors. Some contracts provided that contractors would operate temporary facilities owned by the government, or be subject to recapture of excess profits. Profit margins were typically low, but in return contractors sometimes received favorable contract terms to insulate them from unexpected costs.
The Contract Settlement Act of 1944 (CSA) recognized that, because of the extent to which American industry had been integrated into the war effort, any issues with the payment of claims when the war ended could imperil the entire economy. The CSA provided procuring agencies with authority “notwithstanding any provisions of law” to “agree to assume, or indemnify the war contractor against, any claims by any person in connection with such termination claims or settlement.”
As was the intent of these legislative and executive acts, American industry roared to life, flooding the operational theaters with ships, planes, tanks, ordnance and fuel, and propelled the Allies to victory. But this overwhelming effort had ill effects as well. Due in part to both the extraordinary pace of production, and the less stringent environmental regulations of the time, large amounts of toxic chemicals were released at hundreds of sites around the country.
Three-and-a-half decades later, in the face of mounting public concern about environmental pollution, Congress enacted the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). CERCLA authorizes the Environmental Protection Agency, if it determines a site poses “an imminent and substantial endangerment to the public health," to sue certain responsible parties for the costs of cleanup. Many of the sites identified by the EPA under CERCLA (commonly called “Superfund” sites) are the product of the extraordinary wartime effort, and the extraordinary defense contracts that enabled it. This set the stage for decades of litigation to allocate financial responsibility for the cleanup between the contractors (and often their corporate successors) and the government.
II. CERCLA Liability Generally
CERCLA liability will attach to any entity that owns or operates a contaminated facility, or owned or operated a facility where hazardous substances were disposed of in the past, as well as a few other categories related to transporting or arranging for the improper release of hazardous materials. CERCLA liability is strict, joint, and several. This means that often one party may be compelled to begin cleanup (or reimburse EPA for beginning cleanup) and then will have to seek contribution from other liable parties. The liability was structured this way to ensure that there would always be a party available to pay for cleanup, and to disincentive companies from engaging in prohibited activities. Even if a corporation sells a polluted facility before the pollution is discovered, they will still be liable as a “past owner” or “operator.” Courts often note that CERCLA should be construed liberally in view of its remedial purpose to achieve its twin goals: “(1) enabling the EPA to respond efficiently and expeditiously to toxic spills, and (2) holding those parties responsible for the releases liable for the costs of the cleanup.”
Under these standards, both defense contractors and the government (which specifically waived sovereign immunity related to CERCLA claims) may be liable for some of the cleanup costs. But the extent of liability for each party is determined by comparing the role that each played in causing the pollution. The characterization of which entity was an “operator” is significant because of the way courts equitably apportion CERCLA contributions among the responsible parties. There is no fixed formula – instead, courts look at various sets of factors. One such set is the “Gore” factors, named after an unsuccessful but nonetheless influential attempt to pass an amendment to CERCLA in 1980 by then-Representative Al Gore. Another similar set of factors are known as the Torres factors. A common theme is that liability will be more heavily apportioned to a party with more "knowledge and/or acquiescence […] in the contaminating activities." The tests established for the “operator” label tend to track closely with this language, and therefore being designated as an “operator” often leads to a large share of liability. The analysis of which entity was “operating” a facility, or portion thereof, has evolved over time as discussed in the next section.
A. FMC Corp. Suggested Broad Government Liability Even for Regulatory Oversight
In 1994, the Third Circuit decided FMC Corp. v. United States. The case established a framework by which the US government could be held liable as an “operator” for acts it took in a regulatory capacity. Commentators at the time were concerned that, because the government is the ultimate “deep pocket,” this could lead to a massive amount of CERCLA liability looping back onto the government. While not explicitly overruled, FMC Corp. has been limited by subsequent cases. But the decision is still relevant as its fact pattern, while rare, is not unique in the WWII-era contracting context.
FMC Corp. concerned a facility located in Front Royal, VA (then owned by corporate predecessor American Viscose) that produced high tenacity rayon (“HTR”) for plane and vehicle tires. Ordinarily the tires would have used rubber, but 90% of the United States’ rubber supply came from the Pacific, which was cut off after Pearl Harbor. The facility was in fact converted from producing textile rayon to HTR largely at the behest of the government. In 1982, inspections revealed elevated levels of carbon disulfide in the ground water around the plant. Carbon disulfide is a volatile organic compound capable of causing neurological damage with chronic exposure.
After the EPA notified FMC of its potential liability under CERLA, FMC filed suit seeking monetary contribution from the government under section 113(f) of CERCLA. FMC argued that the government was “so pervasively” involved in directing the activities at the facility that it should pay some, if not all, of the cleanup costs. The government admitted that it effectively controlled many aspects of the operation at the American Viscose plant, but argued that it did so only in a regulatory capacity, and that it could not be held to be an “operator” for purposes of CERCLA when it was acting only as a regulator.
The FMC Corp. court looked to cases in the parent-subsidiary liability context, and chose to apply the same “substantial control” and “active involvement” test to governmental actions for purposes of CERCLA liability. The court found it important that, even if the government was primarily “regulating,” it:
“determined what product the facility would manufacture, controlled the supply and price of the facility's raw materials, in part by building or causing plants to be built near the facility for their production, supplied equipment for use in the manufacturing process, acted to ensure that the facility retained an adequate labor force, participated in the management and supervision of the labor force, had the authority to remove workers who were incompetent or guilty of misconduct, controlled the price of the facility's product, and controlled who could purchase the product.”
The court ultimately found that the government was an “operator” of the plant. To the extent that this result was not what Congress may have intended when it adopted CERCLA, the court noted that amending the statute was within the power of Congress, not the Courts.
B. Bestfoods Narrowed the Operator Liability Standard
Four years later, the Supreme Court decided United States vs. Bestfoods. Bestfoods dealt with the question of under what circumstances a corporate parent could be held liable as an operator under CERCLA for the actions of a subsidiary corporation. Because FMC Corp. and other earlier defense contract related decisions had examined governmental vicarious liability under CERCLA as being the same as the inquiry for a “non-governmental entity,” Bestfoods would have a direct impact on government CERCLA liability.
Bestfoods found that a subsidiary “so pervasively controlled” by a parent such that it would warrant veil piercing in the corporate law context could be held derivatively liable for the acts of the subsidiary. This is a high standard—even a parent and a subsidiary that share officers and directors will not necessarily meet it. But even if the conduct of a parent would not warrant veil piercing, the court found that “CERCLA prevents individuals from hiding behind the corporate shield when, as 'operators,' they themselves actually participate in the wrongful conduct.” Thus, “[u]nder CERCLA, an operator is simply someone who directs the workings of, manages, or conducts the affairs of a facility… specifically related to pollution, that is, operations having to do with the leakage or disposal of hazardous waste, or decisions about compliance with environmental regulations.” This standard has been interpreted to require involvement in environmental decisions on a frequent, often “day-to-day” basis.
It is unclear how FMC Corp. would have been decided under this standard. While it appears that the government did exercise some day-to-day control, it is not clear that this control had the required nexus to the actual pollution. What is clear is that this standard is intensely factual in nature. For all the record developed in FMC Corp., more might have been needed to determine if the government’s day-to-day input over personnel and other issues had the required nexus to the pollution.
C. Recent Cases Exemplify this Narrower Standard
Two recent cases demonstrate how much more difficult it is to assign “operator” liability to the government after Bestfoods. Exxon Mobil Corp. v. United States involved two sites in Louisiana where the production of avgas for the war effort led to contamination of the Mississippi River. Exxon argued that many activities at the site were performed out of fear that the refineries would be seized by the WPB if production quotas were not met. The court rejected this argument, finding that the government acted more like a “very interested consumer,” and did not direct day-to-day activities. The court also found persuasive that fact that some of Exxon’s contracts contained clauses stating that certain specifications and quantities would be “determined by negotiation,” as opposed to simply dictated by the government.
Exxon further argued that government personnel were at the site every day, performing inspections. The court cited in response other post-Bestfoods cases where daily inspections related to contract compliance and worker safety were insufficient. Ultimately, the government was not determined to be an “operator” of the avgas refineries under CERCLA.
A second case, TDY Holdings, reached a similar result. TDY was the corporate successor of several corporations which had operated a facility near San Diego international airport that performed aeronautical fabrication and testing as a contractor to the government between 1939 and 1999. Even though it was undisputed that the government “owned some of the equipment related to the contamination, and observed and knew of TDY's production processes and maintenance practices that released contaminates into the environment” the government was found to be merely a “past owner” and not an “operator.” TDY argued that adherence to military specifications (mil specs) led inevitably to pollution, but the court found that the mil specs did not dictate how by-product chemicals should be managed, contained, or disposed of. The court also explicitly distinguished FMC Corp. on the grounds that TDY actively sought out defense work, and was never “ordered, coerced, or forced” to operate as a defense plant. TDY was assigned 100% of the cleanup costs as the “operator,” even though the government had been found to be a “past owner” of some facilities.
III. Shell and E.I. DuPont Establish the Framework for Litigation over Indemnification Clauses
With the window to assign the government “operator” liability in all but extreme cases closed, litigants have explored other ways to shift cleanup costs to the government. One method that has succeeded has been to rely on special indemnification clauses that were included in some WWII-era contracts. Unlike the in-depth factual analysis required to establish “operator” liability, this analysis involves primarily questions of law. Specifically, application of these clauses depends on whether or not the clauses extend to CERCLA liability (which was unforeseen at the time of their execution). If the clauses do cover CERCLA liability, it then must be examined whether or not the Anti-Deficiency Act prohibits payment of indemnification under the clauses and, if so, whether the ADA was effectively waived by the Contract Settlement Act of 1944.
In 1940, the government contracted with E.I. du Pont to build a plant in Morgantown, WV to produce munitions-related chemicals. E.I. du Pont was to construct and operate the plant, but the facilities would be owned by the government. E.I. du Pont was to be paid a fixed fee for the operation of the plant, but the government affectively owned all of the output—there were no products “sold” to the government. The contract contained an indemnification clause that read:
“the Government shall hold [E.I. du Pont] harmless against any loss, expense (including expense of litigation), or damage (including damage to third persons because of death, bodily injury or property injury or destruction or otherwise) of any kind whatsoever arising out of or in connection with the performance of the work.”
The court had no difficulty determining that this clause extended to CERCLA liability based on its broad, non-limited language. The court then turned to the question of whether the Anti-Deficiency Act (ADA) barred payment under the indemnification clause. The trial court had determined that the ADA, which bars payments in excess of the amounts appropriated by Congress for a particular contract, did bar payment of CERCLA indemnification. The Federal Circuit did not question this general conclusion, but instead focused on whether payment was otherwise “authorized by law” as an exception to the ADA.
Specifically, the Federal Circuit considered whether the Contract Settlement Act of 1944 (CSA), designed to ensure rapid settlement of war related claims, could overcome the general prohibition of the ADA. The CSA provided that certain agencies:
“shall have authority, notwithstanding any provisions of law other than contained in this chapter, (1) to make any contract necessary and appropriate to carry out the provisions of this chapter; (2) to amend by agreement any existing contract, either before or after notice of its termination, on such terms and to such extent as it deems necessary and appropriate to carry out the provisions of this chapter; and (3) in settling any termination claim, to agree to assume, or indemnify the war contractor against, any claims by any person in connection with such termination claims or settlement.”
The Federal Circuit agreed with E.I. du Pont that this language “grant[ed] the President the authority to delegate to departments and agencies contracting power virtually unfettered by contract law, including the ADA.” The case was remanded for entry of judgment in E.I. du Pont’s favor—the government would be liable for any CERCLA costs that might be imposed on E.I. du Pont.
Subsequent cases have confirmed that if the CSA is applicable to the contract at issue, then the ADA restriction is not effective. The only issue that remains is whether the particular indemnification clause is “(1) specific enough to include CERCLA liability or (2) general enough to include any and all environmental liability which would, naturally, include subsequent CERCLA claims.” Shell Oil Co. v. United States concerned a contract where the relevant agency had agreed to pay “"any now existing taxes, fees, or charges . . . imposed upon [the Oil Companies] by reason of the production, manufacture, storage, sale or delivery of [avgas].” The Federal Circuit held that future CERCLA liability was a “charge” within the meaning of the contract, and the government was therefore liable to reimburse Shell for it.
The courts’ findings that certain WWII-era contractor indemnification clauses cover CERCLA liability makes this an attractive litigation tactic now that that it is more difficult to assign the government “operator” liability. Of course, not all contracts contained a version of either of the provisions discussed above. Those that did are more likely to be contracts of the type at issue in E.I. du Pont and FMC Corp., where the government and the contractor were undertaking a mode of operation that would not normally be undertaken outside of wartime. These extraordinary contracts are more likely to involve fact scenarios on which the government might also still be determined to be an “operator,” even under the narrow Bestfoods test. But even where the government might be deemed an “operator,” the indemnification clause strategy has the advantage of providing a complete bar to contractor liability as opposed to requiring apportionment, and also does not require intense factual investigation.

 The government was determined to be an operator of several discrete facilities related to the litigation, including an ordinance shop. This finding was based on correspondence showing that the government “made specific decisions about waste disposal and environmental compliance,” was aware of the pollution, and decided to continue polluting.
