The National Environmental Policy Act1 requires federal agencies to ascertain and evaluate the possible environmental effects of federally regulated energy infrastructure proposals. But this broad statutory requirement leaves great uncertainty as to which hypothetical risks of environmental harm must be evaluated, and which risks may be set aside as too contingent or otherwise improbable to merit review. Recent events—the Japanese tsunami that disrupted a nuclear power plant, for example, or the deepwater Gulf of Mexico oil spill—remind us that seemingly unthinkable disasters can occur, posing a significant threat of harm to the environment. But two recent court of appeals decisions have created a circuit split on the question of precisely how agencies should approach the possibility of low-probability, high-impact events—or, as they have come to be known, “Black Swans.”
The Tsunami and the Tepco Nuclear Plant
On March 11, 2011, a 9.0 magnitude earthquake twenty miles below the surface of the Pacific Ocean triggered a tsunami.2 The thirty-foot waves raced to Japan’s shore, unleashing a measure of devastation that stunned the worldwide audiences that watched the aftermath in unforgettable television footage.
Of the earthquake’s innumerable casualties, the most significant was Tokyo Electric Power Co.’s (“Tepco’s”) Fukushima Daiichi nuclear plant. When the tsunami struck, three of Fukushima’s six boiling-water nuclear reactors were actively operating, their plutonium rods fueling the reactions that supplied electric power to Tepco’s customers. Fukushima was utterly unprepared to handle the events that ensued: the earthquake and tsunami cut off the plant’s outside power supply, as well as its backup diesel generators, leaving Fukushima unable to sufficiently cool the reactor cores or spent fuel pools.3 As the crisis continued, hydrogen buildup led to large explosions at the three reactors, releasing radiation into the atmosphere.4 Each of the three reactors suffered a meltdown,5 and the seawater that was allowed to flood the reactors, in a desperate attempt to cool them, spread radiation into the ocean.6
Tepco and Japanese regulators had designed Fukushima to handle the tectonic events that regularly strike Japan, but even they did not design a plant capable of handling this earthquake, Japan’s largest in three centuries.7 “The disaster plan didn’t function . . . It didn’t envision something this big.”8 Tepco and the regulators “fail[ed] to envision the kind of worst-case scenario that befell Japan: damage so extensive that the plant couldn’t respond on its own or call for help from nearby plants.”9
Or, as Fukushima’s own report on its accident-management protocols acknowledged, “The possibility of a severe accident occurring is so small that from an engineering standpoint, it is practically unthinkable.”10
“Practically unthinkable”—an ironic choice of words. For while virtually every aspect of this tragic chain of events was unprecedented, that particular characterization of an unforeseen disaster is itself well-precedented. In just recent memory, the United States has witnessed several major infrastructure catastrophes that were quickly characterized, after the fact, as “unthinkable.”
Most recently, of course, was the April 2010 explosion at the Deepwater Horizon oil rig at the Gulf of Mexico’s Macondo Prospect. The unexpected failure of a blowout preventer to protect against a methane bubble resulted in an explosion that destroyed the rig and allowed nearly five million barrels of oil to leak into the Gulf.11 BP urged that the disaster was caused by no single action (or company): “Rather, a complex and interlinked series of mechanical failures, human judgments, engineering design, operational implementation and team interfaces came together to allow the initiation and escalation of the accident.”12 According to BP’s CEO, there was “no precedent” for the confluence of events that led to the explosion. Or, as BP’s spokesmen stated in Fukushima-esque terms, the blowout preventer’s failure “seemed inconceivable.”13
Now, with the benefit of hindsight, those once-“unthinkable” risks are now very, very thinkable. And so U.S. nuclear facility operators—and nuclear power’s critics, and Congress—are working to ensure that U.S. reactors are protected from the particular threats that ultimately doomed Fukushima.14
But what about those risks that we cannot see in hindsight—because they have not previously occurred? The purely hypothetical risks for which there is no precedent? How could regulators efficiently and effectively guard against the unprecedented earthquake triggering cascading failures at a coastal nuclear facility, in the years before the Fukushima disaster? Or, how could regulators sitting in judgment of a deepwater oil drilling operation meaningfully consider the environmental harm that could ensue if a blowout preventer unprecedentedly failed to protect against a methane bubble, long before the Deepwater Horizon incident?
“Black Swans” and the Precautionary Principle
These are no small questions. In fact, the very question of how to anticipate—and guard against—the risk of high-impact, low-probability events has been the subject of a contentious intellectual debate in recent years.
Much of the debate has been sparked by—and captured by the title of—Nassim Taleb’s 2007 bestseller, The Black Swan. In that book (which is unrelated to the award-winning 2010 film of the same name), Taleb argues that people inherently underestimate the risk of high-impact, low-probability events in their daily lives. We rely on models, habits, assumptions, and ex post facto explanations that rely too heavily on past facts, in a manner that blinds us to events that have not previously occurred, but which could occur—with catastrophic effect.15 Taleb’s choice of title refers to one such example: “[P]eople in the Old World were convinced that all swans were white” because only white swans were seen in the known world. But then Australia was discovered, and with it black swans. And for all of the innumerable white swans that had been seen since time immemorial, it took only one black swan to disprove the theory that all swans were white.16
Thus, Taleb assigned the name “Black Swan” to events with three attributes: they are (1) outlier events beyond the realm of regular experience, with (2) an extreme impact, but (3) for which human nature leads us to create ex post facto explanations that make the event seem explainable and predictable.17 The concept and title have quickly come to direct the public debate over how best to guard against unforeseen events in financial markets, energy infrastructure, and other critically important aspects of modern life.18
Of course, while Taleb is perhaps the most prominent participant in the public debate over risk management, he is not alone in grappling with the question of how to manage the threat of unmanageable risk. Judge Richard Posner, law professor Cass Sunstein, political scientist Francis Fukuyama, and others have weighed in with insightful analyses,19 but regulators and industry officials seeking practical guidance for the mitigation of unforeseeable or seen-but-highly-unlikely risks will find little help in the academic literature. For example: Judge Posner’s variation on his familiar framework of cost-benefit balancing, applied to protect against catastrophic risk, is elegant in theory.20 But it ultimately offers no real guidance in the absence of reliable evidence of the true risk of harm, the magnitude of harm, or the cost of guarding against the threat.21
Given both the lack of reliable guideposts for case-by-case analysis, and the possible risk of harm at stake when considering the threat of low-probability, high-impact events, regulators and advocates often fall back on a heuristic commonly known as the “precautionary principle.” As Sunstein summarizes it, the precautionary principle instructs us, “[i]n case of doubt,” to “[a]void steps that will create a risk of harm. Until safety is established, be cautious; do not require unambiguous evidence. In a catchphrase: better safe than sorry.”22
Perhaps the best-publicized—and most controversial—application of the precautionary principle was that offered by Vice President Cheney, with respect to the Bush Administration’s strategy in the early days of the Global War on Terror: because an unexpected terrorist attack could have catastrophic consequences, even “a one percent chance” of occurrence would suffice to trigger responding as if the attack were “a certainty.”23
Or, to take an example from the other side of the political aisle, many critics of climate change and other environmental risks have presented their criticisms in similar terms. Speaking to the question of man-made climate change, New York Times columnist Thomas Friedman urged, “When I see a problem that has even a 1 percent probability of occurring and is ‘irreversible’ and potentially ‘catastrophic,’ I buy insurance. That is what taking climate change seriously is all about.”24
But as a heuristic, the precautionary principle suffers no shortage of defects all its own. In its strongest form, the principle is “paralyzing” because it effectively “forbids all courses of action, including inaction.”25 As Sunstein explains, in any case where “there is a possibility of serious harms, and no authoritative scientific evidence suggests that the possibility is close to zero,” then if “the burden of proof is on the proponent of the activity or process in question, the precautionary principle would seem to impose a burden of proof that cannot be met.”26 In other words, when a course of action implicates the Precautionary Principle, but so do its alternatives—including inaction—then the Precautionary Principle offers no solution.
From Theory to Practice:
The National Environmental Policy Act
As a law professor, before he joined President Obama’s Office of Management and Budget as Administrator of the Office of Information and Regulatory Affairs, Cass Sunstein wrote extensively on this subject, especially with respect to climate change and terrorism.27 And, in fact, those are two of the areas in which difficult questions of low-probability, high-impact events arise as a practical regulatory matter, as agencies implement the National Environmental Policy Act (“NEPA”).28
NEPA “is our basic national charter for protection of the environment.”29 But while its prefatory language lays out general substantive environmental goals,30 NEPA’s “mandate . . . is essentially procedural.”31 Unlike other environmental statutes such as the Clean Water Act or Wild and Scenic Rivers Act, or federal infrastructure permitting statutes such as the Natural Gas Act, Federal Power Act, or Atomic Energy Act, it neither imposes new substantive environmental standards nor directs federal or state agencies to impose new substantive environmental standards.32
Instead, NEPA works to supplement the agencies’ enforcement of those substantive standards in cases of federal action—such as an agency’s approval of an application to site a new interstate natural gas pipeline under the Natural Gas Act. Specifically, anytime that an agency proposes to undertake or approve a “major Federal actio[n] significantly affecting the quality of the human environment,”33 such as the approval of an application to construct a federally-regulated energy infrastructure project under the Natural Gas Act or other statute, the agency must take a “hard look” at the possible environmental effects of the project, and the comparable effects of alternative proposals—including the “no-action” alternative—before approving the project.34
By adding that procedural requirement to each agency’s administration of its other substantive statutes, “NEPA . . . makes environmental protection a part of the mandate of every federal agency and department.”35 Its procedural requirements ensure that the agency take action “only after responsible decisionmakers had fully adverted to the environmental consequences of the actions, and had decided that the public benefits flowing from the actions outweighed their environmental costs.”36 Thus, “by focusing the agency’s attention on the environmental consequences of a proposed project,” including its effect on human populations, before issuing a final approval for the project, “NEPA ensures that important [environmental] effects will not be overlooked or underestimated only to be discovered after resources have been committed or the die otherwise cast.”37
NEPA accomplishes this primarily by requiring the agency to prepare an “environmental impact statement” (“EIS”) for any “major Federal action significantly affecting the quality of the human environment.”38 The EIS identifies, inter alia, “the environmental impact of the proposed action,” “any adverse environmental effects which cannot be avoided should the proposal be implemented,” and “alternatives to the proposed action[.]”39
Those broad requirements leave no shortage of discretion to the agency; they leave even more discretion to the underlying applicant, with respect to defining the project’s purpose and alternatives.40 But perhaps the most complex and contentious aspect of the EIS is identifying the “adverse environmental effects” that would be caused by the proposed action and thus must be analyzed by the agency—for precisely the reasons discussed above. A proposed energy infrastructure project, for example, has reasonably certain environmental effects, at least with respect to the geographic footprint of the project, but it also can give rise to no shortage of hypothetical environmental impacts, ranging in likelihood from the probable to the nearly impossible. Even assuming that the agency, the project’s proponents, and the project’s critics could identify all possible contingencies and environmental effects—even the so-called “Black Swans” threats—measuring the actual risk and possible impact of all such threats is effectively impossible.
Under that shadow of uncertainty, NEPA does not impose the Precautionary Principle; it does not require the agencies to consider any and all hypothetical environmental impacts of the project. While “[r]easonable forecasting and speculation” is “implicit in NEPA,”41 “agencies may not be precluded from proceeding with particular projects merely because the environmental effects of that project remain to some extent speculative.”42 Instead, the agency must strike a pragmatic balance:
[O]nly those effects that are “likely” (or “foreseeable” or “reasonably foreseeable”) need be discussed . . . and, as in other legal contexts, the terms “likely” and “foreseeable,” as applied to a type of environmental impact, are properly interpreted as meaning that the impact is sufficiently likely to occur that a person of ordinary prudence would take it into account in reaching a decision.43
This resembles a sliding scale of risk and possible harm:
Danger . . . is not set by a fixed probability of harm, but rather is composed of reciprocal elements of risk and harm, or probability and severity. . . . That is to say, the public health may properly be found endangered both by a lesser risk of a greater harm and by a greater risk of a lesser harm. Danger depends upon the relation between the risk and harm presented by each case, and cannot legitimately be pegged to “probable” harm, regardless of whether that harm be great or small.44
Marshaling those considerations, the Supreme Court’s ultimate standard is effectively tort law’s standard of “proximate causation.” In Metropolitan Edison Co. v. People Against Nuclear Energy, the leading case on this point, the Court expressly adopted this tort concept as guiding the agencies’ inquiry under NEPA. According to the Court, NEPA’s concept of environmental impact should “be read to include a requirement of a reasonably close causal relationship between a change in the physical environment and the effect at issue,” caused by the federal agency’s decision to approve the project at issue.45 The mere risk that the agency-approved project could give rise to environmental impact is not itself environmental impact: “[A] risk of accident is not an effect . . . . A risk is, by definition, unrealized in the physical world.”46 And so where the agency’s action does not directly result in the foreseen environmental effect, but instead is merely the first step in a causal chain with numerous “middle links” preceding the hypothetical outcome, those intervening links may “lengthen the causal chain beyond the reach of NEPA.”47
Applying that standard in Metropolitan Edison, the Court held that NEPA did not require the Nuclear Regulatory Commission, in reviewing a nuclear facility license application, to consider purely psychological harm—“anxiety, tension and fear, a sense of helplessness, and accompanying physical disorders”48—that could be suffered by persons living near the facility, caused by the increased risk of nuclear accident.49
But in rejecting the challenge to NRC’s decision in that case, the Court cautioned against over-reading the Court’s own decision: “We emphasize that in this case we are considering effects”—i.e., the aforementioned “tension and fear”—“caused by the risk of an accident. The situation where an agency is asked to consider effects that will occur if a risk is realized, for example, if an accident occurs at [the nuclear facility], is an entirely different case.”50
Two decades later, in cases once again involving the NRC, two federal courts of appeals split on the question of how to apply NEPA under the post-9/11 shadow of nuclear terrorism.
Ninth Circuit: Over-Simplifying the “Chain” Of Events
After the al Qaeda strike of September 11, 2001, the threat of terrorist attack on the nation’s nuclear infrastructure was immediately cognizable. Indeed, the “9/11 Commission Report”—or, the Final Report of the National Commission on Terrorist Attacks Upon the United States—reported that both 9/11 mastermind Khalid Sheikh Mohammed and Mohammed Atta, the al Qaeda agent who carried out the attack, had considered targeting U.S. nuclear facilities.51 And the threat of terrorist attack quickly became a central issue in the NRC’s review of applications for nuclear infrastructure.
Just three months after the attacks of 9/11, Pacific Gas & Electric Co. applied to NRC for a license to construct and operate a spent fuel storage installation at the site of its Diablo Canyon nuclear power plant.52 San Luis Obispo Mothers for Peace, a non-profit organization opposed to the project, challenged the application and the agency’s preliminary approval on the ground that, inter alia, they “fail[ed] to address environmental impacts of terrorist or other acts of malice or insanity[.]”53 But the NRC ultimately approved the project application; it refused to analyze the environment impact of a terrorist attack on the facility, concluding that NEPA review of that issue was unnecessary because, inter alia, “the possibility of terrorist attack is too far removed from the natural or expected consequences of agency action”; and in any event “the risk of a terrorist attack cannot be determined,” such that “the analysis is likely to be meaningless.”54
But on a petition for review, the Ninth Circuit vacated the NRC’s decision, holding that the NRC violated NEPA by categorically refusing to include in its NEPA review the threat of terrorist attack. Importantly, the Ninth Circuit held the NRC could not ignore the threat of terrorist attack simply because, as NRC concluded, “the possibility of a terrorist attack . . . is speculative and simply too far removed from the natural or expected consequences of [NRC’s] action . . . .”55 That argument, the Ninth Circuit concluded, was premised upon a misreading of the Supreme Court’s decision in Metropolitan Edison.
According to the Ninth Circuit, “[t]he events at issue here, as well as in Metropolitan Edison . . . form a chain of three events: (1) a major federal action; (2) a change in the physical environment; and (3) an effect.”56 The chain may have been the same in both Metropolitan Edison and the present case, but the two cases involved different connections in the chain: Metropolitan Edison “was concerned with the relationship between events 2 and 3 (the change in the physical environment, or increased risk of accident resulting from the renewed operation of a nuclear reactor, and the effect, or the decline in the psychological health of the human population).”57
“In the present case,” by contrast, “the disputed relationship is between events 1 and 2 (the federal act, or the licensing of the Storage Installation, and the change in the physical environment, or the terrorist attack).”58 Those connections in the chain, according to the Ninth Circuit, presented precisely the type of case that the Supreme Court stated it had not decided in Metropolitan Edison: namely, one in which “an agency is asked to consider effects that will occur if a risk is realized, for example, if an accident occurs . . . .”59
Thus, the Ninth Circuit concluded, where (as in the present case) the question is what change in the physical environment could result from the federal agency’s action, “[t]he appropriate inquiry is . . . whether such attacks are so ‘remote and highly speculative’ that NEPA” does not require their consideration.60 The court determined that the NRC’s categorical refusal to consider the possibility of terrorist attack was unreasonable.61 And the court further held that the NRC could not avoid NEPA’s requirement by concluding that the risk of terrorist attack was “unquantifiable.”62
The Ninth Circuit’s analysis appears correct in at least one respect: in Metropolitan Edison, the Supreme Court specifically stated that it was “considering effects caused by the risk of an accident,” and not the “effects that will occur if a risk [of accident] is realized.”63
But the Ninth Circuit erred in attempting to equate its case and Metropolitan Edison as simply involving two separate segments in the same three-point chain. The Supreme Court made clear that Metropolitan Edison’s “chain” involved not three linked points, but four: (1) the agency’s action, (2) the resulting increased risk of nuclear incident, (3) the project opponents’ perception of that risk, and (4) the physical or physiological effects resulting from their perceiving that risk.64 The Court held that NEPA required no analysis of that final link because both the second and the third links, together, stretched the causal chain too far.65
And Metropolitan Edison’s causal chain was not the only one that the Ninth Circuit misperceived; it also misperceived the causal chain at issue in the case at bar, which also involved not three links but at least five: (1) the agency’s action, (2) the resulting risk (i.e., the increased opportunity for terrorist attack), (3) terrorists’ identification of that opportunity, (4) terrorists’ action to seize that opportunity, and (5) the results of the terrorists’ action. This causal chain is at least as lengthy and uncertain as the chain in Metropolitan Edison.
And that uncertainty undermines the remainder of the Ninth Circuit’s analysis. Even assuming that San Luis Obispo Mothers for Peace involved a case in which the NRC was only being asked “to consider the effects that will occur if the risk is realized,” there remain several “links” of uncertainty. The “risk” is “realized” when terrorists identify their new opportunity for attack, but there remain the uncertainties of whether the terrorists will decide to seize that opportunity, whether the terrorists effect that decision by conducting a successful attack, and what the effects of that attack would be.
Third Circuit: Seeing Each Link in the Chain
While San Luis Obispo Mothers for Peace was pending in the Ninth Circuit, another company, AmerGen Energy, applied to NRC to renew its operating license for the Oyster Creek Nuclear Generating Station.66 New Jersey regulators urged that NRC’s NEPA review required the consideration of a threat of airborne attack on the nuclear plant.67 In this case, as with Pacific Gas & Electric’s aforementioned application, NRC concluded NEPA “imposes no legal duty on the NRC to consider intentional malevolent acts” because such acts are “too far removed from the natural or expected consequences of agency action.”68
The Third Circuit affirmed NRC’s analysis. Repeating Metropolitan Edison’s instruction that a mere risk of effect is not itself an effect, the Third Circuit traced the links in the causal chain, beginning with the NRC’s approval of the project and ending with the hypothetical terrorist attack.69 And in so doing, the Third Circuit identified some of the links that the Ninth Circuit had not considered. To analyze the threat of a terrorist attack would necessarily require the analysis of the nuclear facility’s “status as a particularly vulnerable terrorist target”70—or, in terms of the five-link chain discussed above, the question of both how the terrorists would perceive the target, and whether their action on such a perceived opportunity would bear fruit. And with respect to the actual effect that such a terrorist attack would cause, that in turn depends on “[t]he government agencies specifically charged with preventing an airborne terrorist attack,” which “also serve as intervening forces.”71 Or, stated differently, “an aircraft attack on [the nuclear facility] requires at least two intervening events: (1) the act of a third-party criminal and (2) the failure of all government agencies specifically charged with preventing terrorist attacks.” In light of that lengthy causal chain, the Third Circuit “conclude[d] that this causation chain is too attenuated to require NEPA review.”72
The Third Circuit recognized that its analysis effectively created a split with the Ninth Circuit.73 But it found that split to be no cause for abandoning its analysis and endorsing the Ninth Circuit’s.
* * *
The petitioners challenging NRC’s approval of the Oyster Creek relicense did not seek further review at the Supreme Court. Thus, for the time being, the Court will have no opportunity to resolve the circuit split. Nevertheless, in light of the heightened public awareness of the unexpected threats to nuclear facilities and other infrastructure that has followed the Gulf oil spill and Japanese tsunami, we can expect critics of energy infrastructure projects to cite the possibility of “Black Swan” events—terrorism, natural disasters, or otherwise—as necessary considerations in NEPA analyses. And the fundamental uncertainty of such hypothetical threats, if they are required to be considered in NEPA analyses, will only lengthen the agencies’ process for reviewing infrastructure proposals, and offer litigants greater opportunity to overturn federal approvals of challenged projects.
The answer is neither to require agencies to attempt to predict and analyze the truly unpredictable, nor to give agencies carte blanche to ignore the possibility of such events. Rather, it is incumbent upon agencies to do their best, in good faith, to separate the reasonably foreseeable from the truly unknowable; to analyze the former as rigorously as possible; and to act prudently in light of the latter. We cannot pretend to be perfectly protected against Black Swan events, nor can we allow an exaggerated application of the Precautionary Principle to paralyze federal agencies and the development of energy infrastructure.
