ORDER signed by Chief Judge William C Griesbach on 5-15-15 denying 935 Motion seeking additional factual findings; granting 981 Motion for Leave to File. NCR has established its divisibility defense. (cc: all counsel) (Griesbach, William)
UNITED STATES DISTRICT COURT
EASTERN DISTRICT OF WISCONSIN
UNITED STATES OF AMERICA,
Plaintiff,
v.
Case No. 10-C-910
NCR CORPORATION, et al.,
Defendants.
DECISION AND ORDER
Following remand of this case from the Court of Appeals, the United States has filed a
motion seeking additional findings of fact based on the record made at the December 2012 trial
conducted in this action that would reaffirm the court’s original conclusion that the harm to OU4
is not divisible and that NCR is jointly and severally liable. In the government’s view, there is
enough evidence already in the record to answer two of the key questions highlighted by the Seventh
Circuit in its decision remanding the case. If this court agrees with the government’s interpretation
of the evidence, the matter may be resolved without the need for further proceedings. Based upon
the analysis adopted by the Seventh Circuit, however, and the evidence presented at trial, I am
unable to make the findings the government requests. Instead, I find that NCR has established its
divisibility defense. The government’s motion will therefore be denied and NCR’s cross-motion
will be granted.
I. The Trial and the Seventh Circuit’s Decision
On September 25, 2014, the Seventh Circuit affirmed parts of this court’s post-trial decision
but reversed and remanded as to others. As relevant here, that decision directed this court “to
reconsider NCR's divisibility defense consistent with this opinion.” United States v. P.H. Glatfelter
Co., et al., 768 F.3d 662, 682 (7th Cir. 2014). As all of the parties are by now well-aware, the
divisibility defense has two components. The first question asks whether the harm is theoretically
capable of being divided, while the second asks whether there is a reasonable way of apportioning
the damages. Id. at 838.
At trial and in earlier proceedings, the parties, their experts, and the court all viewed the
evidence through the prevailing “binary” lenses that then governed the divisibility analysis.
In
attempting to answer the first of the two divisibility questions, the issue was not how much each
PRP contributed to the concentrations, or toxicity, in OU4, but how much their discharges gave rise
to the need to remediate portions of that river section. Each portion of the river either needed to be
remediated, or it did not; that was why the parties and courts addressing this issue have described
the question as binary. In short, the remedy imposed and its attendant costs were the touchstone of
the entire analysis of harm. For example, I described the efforts of NCR’s expert, Mr. Butler, as
follows:
Butler went about determining which remedial actions, if any, would need to be
applied to different parts of the river, which he had conceptually divided up into
polygons. For instance, if a certain polygon would have a concentration lower than
1 ppm if NCR were the only discharger, he could determine that that polygon would
not need to be dredged or remediated at all. In other cases, a polygon that otherwise
needed to be dredged might have been a candidate for capping (a cheaper remedy)
had NCR been the only polluter. Thus, Butler's analysis determines areas that would
not need to be remediated at all in the NCR-only scenario, as well as areas for which
different remedies could be applied.
2
United States v. NCR Corp., 960 F.Supp.2d 793, 809 (E.D. Wis. 2013).
Based on the fuller record now before it following a bench trial, the Seventh Circuit altered
the prevailing “binary” paradigm and, in essence, directed the parties and this Court to view the
question of divisibility through a different set of lenses. It did so by re-defining the very harm that
NCR’s defense attempts to divide. No longer is the “harm” to be viewed primarily with respect to
the remedy or costs the PCBs might have triggered; instead, the harm is primarily defined with
respect to the PCBs’ actual toxicity, i.e., the “harm to human health and the environment.” Id. at
677. The Seventh Circuit found that this harm is not binary but “continuous,” because the harm
increases in rough proportion to the concentration of PCBs in the water (particularly nearer the
surface). Simply put, the more PCBs, the more harm. Thus, the harm is more properly defined as
a release’s toxicity or danger to health and the environment, as opposed to the release’s propensity
to trigger a costly remedy.1
In many ways this analysis should be much easier because it removes the somewhat
cumbersome link between discharges, remediation rules and cost. If harm is essentially toxicity,
we no longer need to assess whether given discharges would have given rise to the need for a
specific remedy in a portion of the river. Instead, the primary question as to whether the harm is
theoretically capable of being divided is now simply this: to what extent did NCR contribute to the
contamination, or toxicity, in OU4?
“We think the harm would be theoretically capable of
apportionment if NCR could show the extent to which it contributed to PCB concentrations in
OU4.” Id. at 678. As for the second question in the divisibility analysis, the Seventh Circuit
1
Although the harm is the contamination, the Seventh Circuit suggested that the
“damages” to be apportioned would be linked to each party’s causation of remedial response
costs.
3
concluded that if in fact NCR could show the extent to which it contributed to PCB concentrations
in OU4, then “a reasonable basis for apportionment could be found in the remediation costs
necessitated by each party.” Id.
II. Theoretical Divisibility
The question posed by the government’s motion is whether the record as it now stands
provides enough evidence for this court to rule on the two divisibility questions. The government
focuses on the Seventh Circuit’s brief discussion of several experts, who were key to its defense:
The district court thoroughly critiqued the mass-percentage estimates provided by
Simon and Dr. Connolly, and we agree that those estimates likely understated NCR's
contribution to the PCBs in OU4. However, Butler also ran his analysis using the
higher estimates provided by Georgia–Pacific's expert, Dr. John Wolfe. The district
court failed to explain why Dr. Wolfe's mass-percentage estimates were unreliable.
Moreover, apart from its assumption that the PCB contamination in the Lower Fox
River is binary in nature, the district court levied no criticism at Butler's application
of the mass- percentage estimates he used. There may be reasons to find that Dr.
Wolfe's mass-percentage estimates are unreliable, and there may be reasons to find
that Butler's use of those estimates was unsound, but we will not undertake such
factfinding in the first instance. Therefore, we will reverse the district court's
decision on NCR's divisibility defense and remand for further proceedings.
768 F.3d at 678.
The reason this court did not explain why the higher mass-percentage estimates referenced
by Dr. Wolfe were unreliable, however, was because if the harm was binary in nature, it did not
matter. In other words, if the harm at issue was the cost of remediation of those areas in which the
PCB contamination was above the remedial action level of 1.0 ppm and we assume the higher
estimates of NCR’s PCB contamination used by Dr. Wolfe are accurate, the required remedy would
be roughly the same even if NCR was the only source. (ECF No. 729 at 2188-89.) Given the
4
relatively low remedial action level of 1.0 ppm, the court concluded that only if the volume of PCB
discharge attributable to NCR was extremely low, far lower than the estimates used by Dr. Wolfe,
would NCR be able to show that its discharges were not a sufficient or at least necessary cause of
all or most of the remediation required in OU4. 960 F. Supp.2d at 826, n 9.
This understanding of the harm at issue was also the basis for this court’s rejection of Dr.
Butler’s conclusion that the harm was divisible even assuming the larger estimate of NCR’s PCB
discharge utilized by Dr. Wolfe. The court explained in detail why it concluded that Dr. Butler’s
testimony that “(1) NCR's discharges alone produced concentrations below the 1.0 ppm remedial
action level; and (2) the concentration actually exceeded 1.0 ppm, due either to the other parties'
discharges or to a combination of their discharges with NCR's ....was limited and unconvincing.”
960 F. Supp.2d at 811. If, as the Court of Appeals has now held, the harm is to be viewed as
continuous, as opposed to binary, this court’s criticism of Dr. Butler’s approach drops out and Dr.
Wolfe’s estimates become relevant.
It appears from the Seventh Circuit’s decision that its discussion of this evidence was
directed more towards the second divisibility question (apportionment of damages) than the primary
question, which asks whether the harm is theoretically capable of division. In fact, as NCR points
out, the government seemed to have conceded as much during a December 2014 hearing, when its
attorney suggested that “the only remaining issue” is whether NCR can satisfy “step two” and
demonstrate an apportionment that “makes sense.” (ECF No. 960 at 7.) The government insists
that it has not conceded theoretical divisibility, but its briefs have addressed only the apportionment
question.
Whether or not the government actually conceded theoretical divisibility, I conclude that the
5
Seventh Circuit’s decision means, on this record, that the harm is theoretically capable of
apportionment. In short, the Seventh Circuit’s definition of “harm” opens the door to a simple
volumetric approach to divisibility, and Dr. Wolfe’s evidence, as applied by Mr. Butler, suffices to
support such an approach.2
In the government’s view, because Dr. Wolfe himself admitted that his own estimates should
not be grounds for a divisibility analysis, NCR necessarily loses on its defense. From Wolfe’s point
of view, things were just too uncertain to rely on a modeling approach to determine divisibility.
Therefore, according to the government, there would be no sound basis for Mr. Butler to have used
Dr. Wolfe’s own estimates, and thus there is no sound basis to find divisibility. But Dr. Wolfe’s
ultimate conclusion that the harm was not divisible also rests on the assumption that the harm was
binary in nature and that, with a remedial action level of only 1.0 ppm, the remedy would be
approximately the same even if NCR was the only discharger. (ECF No. 729 at 2188-89.) Again,
this is the view that the Seventh Circuit rejected. Now that the harm is seen as continuous, it is
much simpler to conclude that the harm may theoretically be divided. NCR no longer needs to
show how its PCBs contributed to the need to remedy any given portion of the river—an
undertaking requiring detailed modeling. Instead, it is enough to demonstrate what percentage of
the toxicity in OU4 was caused by its discharges.
The question, therefore, is whether Dr. Wolfe’s mass-percentage estimates are reliable.
NCR observes that the government ceded two hours of its time to Georgia-Pacific to allow Wolfe
2
I do not mean volumetric in the sense of dividing harm by how much toxin each party
released. Instead, the analysis here examines how much of each party’s release stayed in OU4.
This requires evidence about the numerous factors that cause particles to embed in the bottom of
a river.
6
to testify during the trial (ECF No. 729 at 2264), and it is thus unusual that it is now backing away
from the very expert whose testimony it earlier seemed very willing to endorse. The United States
points out that Wolfe played a somewhat limited role in the trial, however. He submitted an expert
rebuttal report on behalf of Georgia-Pacific, a discharger in OU4B (near the mouth of the River)
whose natural motivation was to lay most of the blame for the PCBs in OU4 at the feet of the PRPs
upstream, primarily NCR and Glatfelter. As a rebuttal witness, his role was primarily to question
the assessments of NCR’s experts. And Wolfe himself noted that his estimates were subject to
multiple uncertainties.
NCR decided to use Wolfe’s own estimates, however, in an effort to show that even if it
used its adversary’s own data, which of course was quite unfavorable to NCR, the harm in OU4 was
still divisible. This approach perhaps came as something of an afterthought, as the government
points out.
On the eve of trial, Mr. Butler served a supplemental expert report in which he
incorporated some of Wolfe’s estimates. But Butler believed Wolfe’s estimates had not involved
the entirety of OU4 but merely its lower half, and so Butler made his own projections about what
Wolfe would have concluded about OU4A. Then, on cross-examination, Butler learned that Wolfe
had actually made estimates for OU4A, which blamed NCR for 43% of the PCBs in OU4A. Armed
with this knowledge, Butler then testified in surrebuttal, incorporating Wolfe’s 43% figure for
OU4A and his 27% figure for OU4B.
(Actually Wolfe had lumped together NCR and CBC
Coating, a smaller discharger also in OU2.)
It is true that Wolfe’s estimates are subject to multiple uncertainties, including assumptions
about releases, dredging and the like.
But those are uncertainties that essentially go with the
territory. In rejecting NCR’s modeling experts’ conclusions, for example, my analysis was driven
7
primarily by the unreliability of the inputs to their framework, most particularly the lowball
assumptions about PCB discharges used by NCR’s expert, Mr. Braithwaite. (ECF No. 794 at 32.)
I noted problems inherent in Dr. Jones’ modeling technique, but did not find such problems to be
a critical flaw. (Id. at 44.) The point is that the modeling of OU4 was not the key problem, for
NCR or anyone else, and the uncertainties identified by Dr. Wolfe were, by their nature, the kinds
of issues that would bedevil the divisibility question in any river with multiple PRPs and an
imperfect historical record.
More importantly, any uncertainty about Dr. Wolfe’s analysis is lessened now that the
definition of harm has been de-linked from the remedial rules. Wolfe’s earlier belief that things
were too uncertain and complicated is not particularly surprising, given the difficulty inherent in
attempting to link PCB discharges to remedial action and costs, etc. Under that framework, it was
important to be able to identify how each party’s discharges gave rise to remedial action, and that
analysis was driven by whether NCR’s discharges pushed each subsection of the river past the 1.0
ppm remedial action threshold.
Modeling was paramount.
That analysis was much more
complicated than one based simply on identifying how much NCR’s discharges contributed to the
contamination in OU4, without respect to the remedy imposed or the 1.0 ppm threshold. The
playing field now is different. Even if Wolfe’s model was not “designed” to be used for divisibility
or apportionment under the old framework, the new paradigm demands much less from an expert.
Now, it would be enough if Wolfe were able to provide reasonable estimates as to how much of
NCR’s discharges contributed to the contamination in OU4. Such an estimate would suffice, on its
own, to answer the first question, namely, whether the harm is theoretically capable of
apportionment. “We think the harm would be theoretically capable of apportionment if NCR could
8
show the extent to which it contributed to PCB concentrations in OU4.” 768 F.3d at 678.
The government’s strongest objection is that Butler really didn’t do anything else once he
adopted Wolfe’s estimates.
Recall that part of Butler’s primary analysis (using NCR’s other
experts) involved calculating PCB concentrations on a cell-by-cell basis based on the 1600 core
samples from OU4. He did this because the “harm” was defined with respect to the remedy, and
the remedy varied based on the location of the contamination. But in doing so, Butler was relying
heavily on NCR’s other experts, not Wolfe, in linking the PCBs to the remedy and costs for each
subsection of the river. In contrast, in using Dr. Wolfe’s estimates, Butler simply applied Wolfe’s
percentages (e.g., 43%) to the known concentrations in all the core samples for each half of the
river. For example, if a given core had a concentration of 35 ppm, the NCR’s share of that
contamination would be about 15 ppm, or 43%. Thus, rather than the location-specific analysis he
undertook with respect to all of the different locations in the river, all of which have different
concentrations, Butler simply assumed that if NCR contributed 43% of the PCBs to OU4A, then
it also caused 43% of the concentration, or “harm” to that half of the river as well.
The government argues that doesn’t cut it because it is well-established that different
portions of the river had different concentrations attributable to OU2 sources. For example, areas
near the De Pere Dam have been shown to be the product largely of OU2 sources. Taking a “one
size fits all” approach to an entire half of the river will obscure the differences in concentrations in
different areas of the river. As the government puts it, “Butler obtained no reliable information
about the actual contributions to the PCB contamination in hundreds of different river locations
when he multiplied Dr. Wolfe’s percentages by the PCB concentrations found in hundreds of
sediment core samples.” (ECF No. 980 at 20.) But even if Butler’s analysis might underestimate
9
NCR’s contributions in certain sub-areas of OU4, that means Butler’s analysis would over-estimate
NCR’s contribution to the contamination in other areas of the river. After all, the 43% figure (for
example), is an average of NCR’s contribution to PCBs that remain in the first half of OU4, and
so an understatement in one portion of the river would have to be balanced by overstatements
elsewhere.
It is worth examining why Dr. Wolfe believed that there was too much uncertainty and that
the river could not be subject to divisibility. Much of his uncertainty was due to the difficulty in
mapping which PCBs deposited in different subsections of the river.
Q. [. . .] because of those uncertainties can modeling be done in the Fox River to
determine precisely where PCBs came from that are now located in OU4?
A. No. In my opinion, this uncertainty makes it impossible to do that precisely.
Q. And because of these uncertainties, Dr. Wolfe, do you think that the Fox River modeling
is a reliable scientific method for dividing or apportioning a river?
A. No, I don't think so.
(ECF No. 729 at 2198.)
In short, much of Dr. Wolfe’s testimony was based on the notion that it was too difficult to
“determine precisely where PCBs came from that are now located in OU4.” (Id.) And he “never
intended to put it forth as precise estimates to be used for an apportionment process.” (Id. at 2224.)
In fact, Wolfe testified that “the challenge of using a modeling approach to answer this question is
too great.” (Id. at 2226.)
Dr. Wolfe thus believed that not only was his model not up to the task, but that modeling
in general could not answer the important questions at hand. But those questions have changed.
The new definition of harm no longer requires (if it ever did) the “precise” polygon- by- polygon
10
approach that was used by NCR under the earlier remedy-based definition of harm. Wolfe was
essentially rebutting an analysis that is no longer relevant, i.e. the notion that the remedy dictates
the definition of harm. Having found that the harm was contamination and that it was continuous,
the Seventh Circuit recognized that each additional quantity of PCBs caused a roughly correlated
additional amount of danger to human health and the environment.
Given this more abstract
definition of harm, it is enough that a party can demonstrate a reasonable correlation between the
volume of PCBs it is responsible for and the concentrations present in the river. Wolfe did this.
In his cross-examination, he conceded that he relied on a well-recognized framework, called WASP,
for his model. (ECF No. 729 at 2263.) He admitted that the purpose of his model was to produce
the best estimates of loads, in connection with 2006 settlement discussions.
(Id. at 2264-65.)
Repeatedly, he was asked if his results were his “best estimates” of the PCB loads of various parties,
and he agreed. (Id.)
Q. And so the net result of your expert modeling work is that ballpark three-quarters
of the PCBs that polluted OU4B were discharged not by NCR but by other parties,
right?
A. Well, I would agree, and I would emphasize the word “ballpark.” I’ve spoken
about the high degree of uncertainty in those estimates.
Q. Ballpark, that sounds right.
A. Well, it’s an accurate reading of the estimates I provided.
(Id. at 2267-68.)
Thus, what’s clear is that although Wolfe believed the divisibility question was too difficult
under the old, binary, framework, he never backed away from his “best estimates” of each party’s
PCB loads, and that is what is currently at issue. The government essentially relies on Wolfe’s
11
uncertainties about a question that no longer matters, while ignoring his relative confidence in the
load estimates he reached, which certainly matter. The inescapable point is that Wolfe conceded
that “ballpark” NCR was responsible for only about a quarter of the PCBs in OU4B, and somewhat
more in OU4A.
Here, Butler simply used Wolfe’s estimates and applied those percentages across the board
to the concentrations found in the core samples. No doubt some of the PCBs from NCR’s plant
were more concentrated near the surface, while others were buried deeper below, due to the vagaries
of the Fox River, which all agree is not materially different from any other river. The government
might have a better argument if there were evidence that PCBs coming from NCR’s plant somehow
had a systematically greater propensity to remain in higher concentrations near the surface
throughout OU4, which would make them more toxic than the basic volumetric analysis would
suggest.
But there was no such evidence, and none is imaginable.
In fact, the government’s
evidence regarding bioturbation, dredging, the seiche effect, and the like, tended to show that all the
PCBs from upstream sources are mixed together and may, in the aggregate, be viewed as fungible.
That is, once they deposited in the river bed, there is no reason to believe that NCR’s PCBs
somehow behaved any differently than the PCBs from Glatfelter, U.S. Paper, CBC Coating, or other
dischargers. Thus, if NCR is responsible for 43% of the PCBs that settled in OU4A, then it is
reasonable to believe that it is also responsible for about 43% of the concentration of PCBs in
OU4A, and that is all NCR must show in order to establish theoretical divisibility.
In sum, even if NCR’s own experts were unconvincing on the question of the volumetric
amount of PCBs NCR contributed to OU4, the evidence submitted by NCR’s adversary set an outer
limit of how much contamination can be attributed to NCR. Importantly, no one has even attempted
12
to argue that NCR’s contributions to the contamination in OU4 were materially more than the
estimates Dr. Wolfe himself used. Thus, NCR has shown that, at worst, it is responsible for roughly
one-third of the PCBs that settled in OU4. Because the “harm” in OU4 is defined with respect to
the concentration of PCBs, and because NCR’s discharges (on average) produced concentrations
in the same fashion as other dischargers, the volumetric estimates shown by Dr. Wolfe and applied
by Mr. Butler sufficiently establish “the extent to which [NCR] contributed to PCB concentrations
in OU4.” 768 F.3d at 678. The harm is therefore theoretically divisible.
III. Reasonable Basis for Apportionment
The second question is whether there exists a reasonable basis for apportionment in the
“remediation costs necessitated by” NCR. Id. NCR’s task, therefore, is to demonstrate a reasonable
estimate of the extent to which its contribution to the contamination in OU4 gave rise to the
remediation costs incurred. (As discussed further below, because costs are correlated with harm,
the analysis is somewhat similar.)
NCR relies on the fifth step of Butler’s analysis. In calculating NCR’s share of the total
OU4 remediation costs, Butler apportioned liability based on the ratio between each PRP’s standalone cost and the total of all the parties’ stand-alone costs. Butler testified that he had used this
stand-alone cost method some fifteen or twenty times since the early 1990s. He explained the
method as follows:
the stand-alone cost analysis looks at what would be the cost if only one party’s
waste or contributions were at a site. And you then estimate the cost for each – for
that party, and then you do that for each party so that you get a stand-alone cost that
is assignable – attributable to each party. And on the basis of those stand-alone
costs, you can then come up with a reasonable method for apportioning the costs.
(ECF No. 726 at 1368.)
13
This approach assumes that the pollution is cleaned up in a joint project among various
polluters, whose combined efforts produce cost savings. For example, if three polluters would have
incurred $200 million cleaning up their pollution independently of each other, they might be able
to do the project together for only $120 million. Thus, under this approach, each polluter shares in
the benefits of group cost savings in proportion to its own stand-alone costs.
The government’s principal objection to this approach is that it is based on averages of
contamination over broad areas (OU4A and B) when what really matters is “variability in the
individual data points.” (ECF No. 980 at 21.) After all, the remedy is not being imposed with
respect to “OU4A” or “OU4B”—the most detail found in Butler’s analysis—but in multiple
subsections of the river. Each PRP contributed different amounts to those subsections, and thus
caused different kinds of remedies (or no remedy at all), and so (the government argues) it would
not make sense to use averages to apportion the costs. For example, it is well accepted that most
of the PCB concentrations directly adjacent to Georgia-Pacific’s plant in OU4B came from GeorgiaPacific itself.
It would therefore not make sense to attribute to NCR a stand-alone cost for
remediating that subsection because Butler’s estimates are an average for the entirety of OU4B.
Given that discharges from Georgia-Pacific’s plant are largely to blame for the toxicity at that
location, such an approach would overestimate NCR’s contribution to the remedial costs in that
section. (The flip side is that the using the averages would underestimate NCR’s contribution to
costs elsewhere in the river, where its own PCBs might predominate.)
There are at least two problems with the government’s argument. First, the Seventh Circuit
found, contrary to this court’s earlier conclusion, that not only was the harm continuous, but the
cleanup costs were continuous as well. That is, it concluded that cleaning up a given portion of the
14
river becomes more expensive the more toxic that portion is.
768 F.3d at 277. If costs are
correlated to contamination (harm), then one would expect the costs may be apportioned on roughly
the same lines as the harm itself: the more harm each party causes, the more cost he is responsible
for. That means the analysis is much simpler, a point made by Burlington Northern itself. There,
for example, the district court concluded that the railroads were responsible for 6% of the
contamination and therefore 6% of the remediation costs. There was no discussion of relationships
between harm and remediation costs, part-per-million thresholds, “variability in the individual data
points,” or anything akin to the kind of detail the government now presses for. In defining harm as
contamination and equating remediation costs with the amount of contamination, the Burlington
Northern approach appears to be what the Court of Appeals has directed be used here. If that is
true, then none of the criticisms of Dr. Wolfe are very persuasive because only the most basic
modeling would be required to establish how much PCB remained in OU4. As discussed above,
Wolfe’s estimates were at the high end of what was reasonable to attribute to NCR, and no expert
or party has argued that NCR’s discharges were materially greater. Accordingly, absent compelling
evidence to the contrary, if NCR contributed to 27-43% of the harm in OU4, it also contributed
roughly the same amount to the cleanup cost.
Just as importantly, it is reasonableness, not scientific precision, that governs the
apportionment analysis. This court has already noted that Burlington Northern seemed to lower the
bar for what kind of evidence would be acceptable for a PRP to establish apportionment. In that
case, it was clear to all concerned that the size of the leased parcel and the amount of time the PRP
had controlled it were not necessarily linked to the amount of harm or damages. Instead, those
metrics were just rough proxies the district court used in the absence of actual knowledge, an
15
absence of information caused by the fact that the railroads did not even argue divisibility. By
comparison, in this case we have scientific estimates from an expert whose experience and
qualifications are unimpeachable and who had no motive to understate NCR’s contribution. Unlike
Burlington Northern, where a fifty-percent “margin of error” was applied, here we can say with
reasonable certainty that NCR is responsible for somewhere between twenty and forty percent of
the PCBs remaining in OU4 (prior to remediation), and that its stand-alone cost for remediation falls
somewhere in that range as well. NCR’s proposal of a 28-percent share falls solidly in the center
of the range of reasonableness.
The government is correct that nothing in Burlington Northern suggests that the district
court’s approach in that case was a paragon of apportionment. It is also possible to read the decision
narrowly in light of the fact that the level of review was limited to whether the court had abused its
discretion. But nowhere did the Supreme Court, which was unanimous, express skepticism about
the district court’s approach; and nowhere in the opinion does one get a sense that the Court would
have done it differently had it been asked to apportion the harm in the first instance.
More
importantly, I am bound by the decision of the Court of Appeals, which states that if NCR could
show the extent to which it contributed to PCB concentrations in OU4, “a reasonable basis for
apportionment could be found in the remediation costs necessitated by each party.” 768 F.3d at 678.
Thus, I conclude that the apportionment here would easily pass muster under the Supreme Court’s
Burlington Northern analysis, and complies with the mandate of the Seventh Circuit. As a high
estimate, NCR is responsible for 43% of the PCBs in the upper half of OU4 and 27% in the lower
half. It requires no stretch of science or logic to conclude that NCR would also be responsible for
a similar amount of the cleanup costs.
16
As I noted above, no one has plausibly argued that NCR contributed significantly more to
the PCB problem than Wolfe estimated. Accordingly, when Butler employed Wolfe’s estimates,
he founded his analysis upon a high estimate for NCR’s contributions, which therefore likely
overstates NCR’s responsibility for response costs in OU4 on the whole. There are clearly areas
where using an average would understate NCR’s contribution, but there are also areas where it will
overstate it (such as hotspots near U.S. Paper and Georgia-Pacific, both significant dischargers).
Although an approach based solely on averages for each half of OU4 is not optimal, in a scientific
sense, nothing in Burlington Northern requires that. And in this case we can expect that the
variance in different subsections will not redound to NCR’s benefit because, using Wolfe’s
numbers, NCR started with a worst-case-scenario estimate of its total average contribution to OU4's
contamination.
In addition, Wolfe’s estimates grouped CBC Coating (the other OU2 source)
together with NCR.
Although CBC was never considered a large discharger, its inclusion also
points to an overstatement of NCR’s responsibility for the cleanup costs.
Finally, it is also worth noting that no one has objected to the use, in general, of a standalone cost method for apportionment. At trial, Dr. Wolfe’s sole criticism of Butler’s analysis was
in Butler’s use of the PCB load estimates, i.e., the inputs from other experts that this court and the
court of appeals found unconvincing. (ECF No. 729 at 2255.) Butler’s reliance on Dr. Wolfe’s
estimates, rather than NCR’s own estimates, solves one of the key problems identified in NCR’s
approach because it avoids reliance on the PCB discharge estimates that this court found far too
low.
17
III. Conclusion
The government relies largely on the fact that Dr. Wolfe himself testified that his own
modeling would not support a divisibility or apportionment determination. But the question now
is much simpler than it was at trial, and Dr. Wolfe confirmed on cross-examination that his
estimates, which were unfavorable to NCR, were his “best” ones. No other expert has credibly
testified that NCR’s contribution to the PCB problem in OU4 was greater than the estimates Dr.
Wolfe found. Mr. Butler simply incorporated those estimates into his framework and concluded
that 28 percent of the costs of remdiation in OU4 are attributable to NCR. Based on the evidence
before me and applying the rationale adopted by the Court of Appeals, I find that Butler’s estimate
of NCR’s share is reasonably accurate. It follows that NCR has established the harm is theoretically
capable of division and that there is also a reasonable basis to apportion its share of the remediation
costs of OU4 at 28 percent. NCR has not claimed the harm in OU2, 3 and 5 is divisible, and thus
its liability for remediation of those areas is joint and several. NCR discharged no PCBs in OU1,
and therefore has no divisible share of the clean-up costs for that area. For these reasons, the
government’s motion is DENIED. NCR is directed to submit a proposed judgment to the Court
within 7 days. The government may respond within 7 days of NCR’s submission.
SO ORDERED this 15th day of May, 2015.
