KRSG’s contribution action against Rockwell alleged that PCBs, which accumulate predominantly in organically rich, Rockwell’s Allegan facility, which produced universal joints quiescent areas of the river, present a grave public health risk, for automobiles and construction equipment, contributed to mainly because they contaminate fish with potentially the PCB contamination at the NPL site. The Allegan facility cancerous chemical waste. Monsanto Corporation produced was in operation from the early 1900s until 1989. In 1987, several different varieties of PCBs all under the brand name the EPA, in an unrelated action, added the Allegan facility to “Aroclor,” (i.e., Aroclors 1242, 1254, and 1260, with the the NPL because of arsenic, cyanide, and chromium higher number corresponding to a greater PCB molecular contamination, but not because of any widespread PCB weight). The KRSG companies used Aroclor 1242 contamination. Soil tests at Allegan did reveal the presence extensively in their de-inking and paper manufacturing of some Aroclor 1254 (along with some Aroclor 1242 and operations for several decades beginning in the 1930s, and 1260) in the groundwater and light non-aqueous phase liquid they also used Aroclor 1254 in transformers, capacitors, (the oily film on top of water).

Throughout the NPL site, definitive proof that Rockwell ever purchased PCBs or Aroclor 1242 is the most prevalent PCB, and the MDEQ and conducted manufacturing operations that would necessitate EPA determined that KRSG companies were responsible for the use of PCB-containing oils, the presence of PCBs on the the bulk of the Aroclor 1242 contamination at the NPL site. property indicated that it did in fact purchase and employ The MDEQ also detected Aroclors 1254 and 1260 at the site, PCBs in its operation. This fact, however, did not resolve the the questionable source of which forms the kernel of these more salient question of whether these PCBs actually found appeals. their way to the Kalamazoo River such that they contributed to the overall pollution for which KRSG was responsible. In All four KRSG companies have not disputed that they are December 1998, the district court held that Rockwell did liable and responsible parties within the meaning of release PCBs into the Kalamazoo River NPL site and was CERCLA. See 42 U.S.C. § 9607.

As responsible determine the precise allocation of costs Rockwell owed to parties with a statutory right to contribution from potentially KRSG. The district court focused almost exclusively on the liable parties, see 42 U.S.C. § 9613(f), the KRSG members quantity of PCBs released by Rockwell versus the amount brought an action in December 1995 against Rockwell, Eaton, leaked by the KRSG companies.

KRSG in contrast to the contribution by [KSRG’s] members.” Joint claimed that Rockwell had deliberately obfuscated this data Appendix (“J.A.”) I at 926 (Dist. Ct. Op. 6/3/00).2 The court in contravention of its statutory duty, and as a result KRSG ruled that KRSG could not recover from Rockwell. KSRG asked the court to use its “equitable power” to reconsider the appealed, arguing that the existence of a logical discontinuity allocation. KRSG did not refer to its motion as a Rule 60(b) between holding a party liable and allocating no costs motion, but on October 15, 2001, the district court ruled as if demonstrated that the district court had abused its discretion. the motion were of the Rule 60(b)(2) mold. The district court We affirmed the district court’s holding in December 2001; denied KRSG’s motion because KRSG filed it after the one- there was no inconsistency, and the district court had broad year time limit for Rule 60(b)(2) motions had expired. discretion to allocate the costs of the remedial investigation, even if the result was a zero allocation to a liable corporation. On appeal, KRSG offers several alternative arguments. See Rockwell II, 274 F.3d at 1049. First, KRSG contends that the district court erroneously considered KRSG’s motion as a Rule 60(b)(2) motion, The immediate circumstances giving rise to this appeal because CERCLA itself provides an equitable basis for were borne of the acrimonious relationship between the EPA reopening an allocation order in the face of changed and Rockwell. In April 1998, the EPA revoked Rockwell’s circumstances. Second, KRSG argues that if Rule 60(b) does authority to investigate the Allegan NPL site because of apply, then the district court should have invoked Rule multiple delays and acts of noncompliance by Rockwell. 60(b)(5) instead of Rule 60(b)(2) because the district court’s Throughout 2000 and 2001, the EPA assumed control of the original order was “prospective” and accordingly subject to investigation and discovered that the Allegan facility in fact Rule 60(b)(5)’s “reasonable time” limitation, as opposed to had dramatically higher PCB levels than Rockwell had Rule 60(b)(2)’s one-year time bar. Third, KRSG implicitly previously disclosed; in some instances the new PCB levels posits that the newly discovered evidence provides a were more than one hundred times the previously reported sufficient basis for reallocating the remediation costs. levels. On August 9, 2001, the EPA ordered Rockwell to abate an “imminent and substantial endangerment to the C. Eaton public health . . . .” J.A. I at 942 (EPA Order, Aug. 2001). The EPA also noted one PCB plume was then entering the KRSG originally brought a contribution action against Kalamazoo River and another was migrating towards the Eaton because Eaton operated three facilities near the river. Kalamazoo River NPL site: Eaton Marshall, Eaton Battle Creek, and Eaton Kalamazoo. The district court granted summary judgment in favor of Eaton as to the Marshall and 2 Kalamazoo facilities in June 1998. Eaton Battle Creek, which Owing to the consolidated nature of this case, the parties submitted is no longer in operation, was located fifteen miles upstream two different joint appendices.

The Battle Creek facility manufactured (constituting ninety percent of the total PCB contamination), automotive parts, namely engine valves and gears, and and while there is evidence that Battle Creek’s wastewater undisputedly released significant quantities of oil into the discharge ditch is heavily contaminated with Aroclors 1254 river for over four decades. The main question attendant to and 1260 at levels comparable to or exceeding the Aroclor the contribution action against Eaton is whether that oil 1242 contamination at the actual NPL site, other companies, contained PCBs and if it did, whether those PCBs affected the including Clark Equipment, used this ditch.

The district court eventually concluded that “the PCBs used in Eaton’s Battle Creek In December 1998, the district court ruled that while the facility were only found in the transformers and capacitors evidence showed that Eaton did utilize some PCBs in its and the hydraulic fluids, and those fluids were not released to electrical and hydraulic equipment, any PCB leaks were the River in any regular or measurable manner.” J.A.

In May 2001, the district court, while maintaining its previous holding that there was only the most KRSG attempted to prove that Eaton PCBs actually entered scant evidence of a measurable PCB discharge into the NPL the river and contributed to the pollution of the NPL site or site from Battle Creek, ruled that it was “constrained to find the RI/FS zone by presenting undisputed evidence that that Eaton is liable for some PCB releases . . . to the Morrow Lake, situated between Battle Creek and the NPL Kalamazoo River.” J.A.

KRSG could not have polluted Morrow Lake, because it lies upstream of the KRSG facilities, so the ensuing 3 KRSG is not responsible for the clean-up of Morrow Lake and other questions were (1) whether Eaton polluted Morrow Lake and areas outside of the defined NPL site, but the RI/FS zone encompasses (2) whether any of the Morrow Lake PCB contamination Morrow Lake and the Kalamazoo River upstream to Eaton Battle Creek. impacted the NPL site such that upstream polluters of Eaton, as a contributio n defendant, is potentially liable for future Morrow Lake should be held responsible as contributing remediation costs only to the extent that PCBs for which it is responsible flowed downstream and impacted the NPL site. Eaton could be respo nsible for the costs of investigating the RI/FS even if its PCB s did not affect the NPL site. Nos. 01-2453;02-2192 Kalamazoo River v. 11 12 Kalamazoo River v. Nos. 01-2453;02-2192 Rockwell Int’l Corp. et al. Rockwell Int’l Corp. et al. The district court then proceeded to receive evidence on the On August 29, 2002, the district court ordered Eaton to pay allocation of response costs between KRSG and Eaton. ten percent of KRSG’s investigation costs in the RI/FS zone KRSG presented the testimonies of Brown and McLaughlin, (ten percent of the total $622,615.79 investigation cost for with the latter stating that he discovered at Battle Creek PCB that portion equals $ 62,261.58). First, the court noted that concentrations ranking in the upper 2% of all PCB samples KRSG had “the burden of proving its equitable right to taken from the NPL site. Many of McLaughlin’s samples, contribution by a preponderance of the evidence.” J.A. II at which demonstrate the presence of high PCB concentrations, 433 (citing United States v. R.W. Meyer, Inc., 932 F.2d 568, came from a drainage ditch leading to the river that Eaton 573-74 (6th Cir. 1991)). Second, the district court rejected shared with Clark Equipment. McLaughlin concluded that McLaughlin’s testimony in favor of Connolly’s, writing that Battle Creek significantly contributed to the PCB while it did “not find Mr. McLaughlin’s conclusions to be contamination at the NPL site. well supported,” it “found the testimony of Dr. Connolly to be more persuasive . . . .” J.A.

It reached this Eaton, in response, relied on the testimony of Connolly, conclusion because of Connolly’s credentials and because it who testified that the PCB concentrations in the ditch and had more confidence in the science underlying Connolly’s several of the sample locations near the ditch’s outfall to the conclusions. In listing the reasons why it disfavored river were not characteristic of the PCB concentrations in the McLaughlin’s position, the district court noted that KRSG’s river between Battle Creek and Morrow Lake. Connolly claim that Eaton principally contaminated the river with essentially posited that the Aroclor 1248, 1254, and 1260 Aroclor 1254 “ignore[d] other potential sources of PCBs concentrations in the general river channel were not located upstream of Eaton’s Battle Creek facility that could consistent with Eaton Battle Creek as a PCB point source. have contributed to the PCBs found in the former channel and Connolly noted the lack of a PCB gradient spanning the current channel of the Kalamazoo River near the Eaton/Clark distance between Battle Creek and Morrow Lake. Generally, ditch.” J.A. II at 444. Consequently, the court agreed with PCB concentrations will be highest near the PCB source and Connolly’s dual contentions that other parties contributed to will increasingly diminish as the distance from that source the PCB contamination in Morrow Lake and that Eaton grows. Comparing the Kalamazoo River to other PCB- discharged only a “de micromis,” J.A. II at 457, amount of contaminated rivers with a “normal” PCB gradient, such as PCBs to the Eaton/Clark ditch. The court found persuasive the Hudson River in New York and the Housatonic River in the argument that only a fraction of this “de micromis” Massachusetts, Connolly highlighted the lack of a gradient amount traveled to Morrow Lake and only a fraction of that stretching from the Battle Creek “source” to further fraction actually passed over the Morrow Lake Dam to the downstream points. Connolly testified that this lack of a NPL site. gradient contradicted the conclusion that Battle Creek was a primary contributor of Aroclor 1254. Connolly bolstered his The court then reached the ten-percent figure by applying theory by suggesting that the absence of a high concentration the “Gore Factors” outlined in Centerior Service Co. v.

Instead, the district court accepted Connolly’s district court erred both in its choice of a standard of liability estimate that only 1.3% of the PCBs in the NPL site could and its application of that standard to the facts in its Eaton have come from Morrow Lake. In sum, the court rejected allocation order. We hold that the district court acted both the notion that Morrow Lake was a primary contributor properly in both instances. of PCBs to the NPL and that Eaton was a primary contributor to the PCB contamination at Morrow Lake.

Second, KRSG claims that the district court (6th Cir. 2001).

ANALYSIS CERCLA allocation mechanism permits the reopening of allocation judgments independent of Rule 60(b). KRSG Because KRSG’s two appeals present completely distinct argues that CERCLA allocation orders are subject to revision legal and factual issues, we discuss each in turn. First, we whenever the equities underlying the decision shift. Finding examine KRSG’s claim that the district court erred in denying no aspect of CERCLA that confirms KRSG’s assertion, we KRSG’s motion to reopen the allocation decision against disagree. Nos. 01-2453;02-2192 Kalamazoo River v. 15 16 Kalamazoo River v. Nos. 01-2453;02-2192 Rockwell Int’l Corp. et al. Rockwell Int’l Corp. et al. KRSG is certainly correct that principles of equity guide KRSG directs our attention to two cases as support for its CERCLA’s contribution provision, but nothing in CERCLA view that CERCLA contains an internal mechanism for compels the conclusion that the equitable underpinnings of an reopening allocation decisions, but neither opinion allocation decision exempt it from the requirement that persuasively proves KRSG’s contention. In Acushnet Co. v. motions to alter judgments be brought under Rule 60(b). Coaters, Inc., 972 F. Supp. 41(D.

There when good cause to do so has developed factually, a motion is nothing in § 9613(f) that suggests that Rule 60(b) is not the supported by a showing of a material change in circumstances proper vehicle for altering a judgment, and quite the opposite, that justifies a change in the allocation of shares among the 42 U.S.C. § 9613(f)(1) clearly states that all claims “shall be parties.” Id. at 63.

It explicitly states that cleanup agreements are to be decisions should be considered ongoing or nonfinal such that entered as consent decrees in a district court. 42 U.S.C. § 9622 (d)(1)(A). there is another method by which relief from judgment may Reliance on § 9622 does not aid KRSG.

Second, § 9622 4 does not explicitly discuss any mechanism for reopening final judgments At oral argume nt, counsel for KRSG suggested that two sections of that is unique to CERCLA Instead it states, “In the case of consent CERCLA support KR SG ’s argument in this reg ard.

The District Court’s Application of a Standard of Eaton could ever be “ruled in” as a PCB contributor and thus Liability that KRSG’s failure to “rule out” other potential contributors was only one part of the district court’s final order. We The district court’s application of a preponderance of the accept neither view, but rather affirm the district court’s order evidence standard is a mixed question of law and fact that we because it appropriately weighed the evidence presented by review de novo. CERCLA contribution plaintiffs must prove both sides to conclude that Eaton was only minimally that they are entitled to reimbursement by a preponderance of responsible for some of the investigation costs incurred by the evidence. See B.F. Goodrich v. Betkoski, 99 F.3d 505, KRSG. 526 (2d Cir. 1996). Nothing in the wording of the CERLCA contribution provision suggests otherwise. See 42 U.S.C. First, there is no indication that the district court clearly § 9613(f). In his August 2002 allocation order, the district erred in its factual findings. Some of the evidence does judge wrote that “although [KRSG] is not required to prove support the theory that Eaton contributed to the PCB its case with . . . mathematical precision, or scientific contamination for which KRSG is responsible.

KRSG asserts that the district PCB contamination at Morrow Lake, were found at Battle court only nominally applied this standard, while effectively Creek. Throughout its history, Eaton Battle Creek discharged holding KRSG to a much higher standard. This argument is large quantities of oil to the river, and the wastewater ditch misguided because the district judge specifically stated that he connecting the Battle Creek facility to the river contained was employing a preponderance of the evidence standard and high PCB concentrations, particularly when one controls for even made clear that KRSG did not have to prove its case the amount of carbon content. Additionally, KRSG’s expert, with “scientific certainty,” or “absolute proof” as KRSG McLaughlin, testified that no other potentially responsible labels it. KRSG’s argument that the allocation order focused party upstream of Morrow Lake, including Clark Equipment too heavily on KRSG’s inability to disprove the possible with whom Eaton shared the wastewater ditch, released as contamination by other facilities on the Kalamazoo River is much PCBs to the river as Eaton. McLaughlin also a contention that the district court misweighed the evidence; concluded that sources closer to Morrow Lake, such as it is not an assertion that the district court applied an Benteler Industries and Consumers Power, did not release inappropriate burden of proof. PCBs to Morrow Lake and thus Eaton must be responsible. 3. The District Court’s Allocation Decision Eaton countered KRSG’s evidence with support of its own and ultimately the court found Eaton’s proof more compelling We affirm the district court’s judgment because the court than KRSG’s. The evidence presented by Eaton showed that neither clearly erred in its factual finding nor abused its it barely used any PCB-laden oils at Battle Creek and that discretion in allocating only a small portion of KRSG’s most of the PCBs found in the wood floors came from closed- investigation costs to Eaton. KRSG contends that the district system transformers and hydraulics. The PCBs in the floor court improperly required KRSG to disprove the complicity were thus the result of incidental and minor spillage, the oil of potentially responsible parties other than Eaton.

There interpretations of the evidence. was no such gradient stretching downstream from Battle Creek, and the MDNR found scant proof of PCB KRSG contends that the district court erred because rather contamination in the fifteen-mile stretch of river between than requiring it to prove Eaton’s complicity, the court forced Battle Creek and Morrow Lake, which indicated that sources KRSG to disprove the potential responsibility of Clark, closer to Morrow Lake, such as Benteler Industries and Benteler, and Consumers Power to the PCB contamination in Consumers Power, primarily contaminated the lake with the Eaton/Clark wastewater ditch and Morrow Lake. This PCBs. Such a conclusion was bolstered by the fact that the argument is flawed. Most importantly, the court did not rely downstream portions of Morrow Lake had higher PCB solely on evidence that other parties may have added to the concentrations than the entrance to the lake closer to Battle PCB contamination in Morrow Lake and the NPL site; in Creek; if there was an upstream PCB source, the upstream making its ruling, the court focused primarily on Connolly’s entrance to Morrow Lake should have had high PCB levels testimony about the lack of a gradient and the evidence that because of its high organic content, but in reality it had a low any PCBs Eaton may have leaked did not contribute to the PCB concentration. pollution upstream of Morrow Lake, in Morrow Lake, or in the NPL site. Additionally, evidence exists that Clark, The district court assessed all of this evidence and Benteler, and Consumers may have contributed to the PCB concluded that Eaton’s use of PCBs was exceedingly minimal contamination upstream of the NPL site. The district court and that any PCBs it did use barely impacted the pollution at did not require KRSG to disprove in any absolute sense the Morrow Lake, let alone the contamination at the actual NPL potential contamination by those facilities, but rather site. In making this factual finding, the district judge rejected considered the significant probability that they added to the the testimony of KRSG’s expert McLaughlin because the pollution for which Eaton was being blamed. Thus, we judge did not believe that it was well-supported and because cannot agree that the district court clearly erred in reaching its he considered Connolly’s testimony to be more persuasive. factual findings. This preference of one expert over another was not clearly erroneous, as the district judge had the opportunity to assess Second, we hold that the district court did not abuse its and observe each expert before making his decision. The discretion by concluding that Eaton was responsible only for district court noted that Connolly “has the most expertise of ten percent of the investigation costs and not responsible for any of the witnesses in the area of hydrogeology and the any future costs of remediating the NPL site. KRSG contends transport of PCBs in the river environment” and that that the district judge abused his discretion, because he Connolly had testified before Congress. J.A. II at 445 (Dist. ignored evidence of Eaton’s culpability and required KRSG Ct. Op. 8/29/02). Based on his acceptance of Connolly’s to disprove affirmatively that other parties, such as Clark and testimony, the district judge concluded that KRSG had not Benteler, were the actual sources of the PCBs. Again, we proven by a preponderance of the evidence that Eaton should cannot accept KRSG’s position. The district judge did not be responsible for a portion of KRSG’s costs. The district ignore evidence of Eaton’s role in adding to the court did not clearly err in making these factual contamination, but rather found other contrary evidence more determinations; they were well-supported by the evidence as probative and persuasive. The district court noted that Eaton may have released some PCBs into the river, although it Nos. 01-2453;02-2192 Kalamazoo River v. 29 30 Kalamazoo River v. Nos. 01-2453;02-2192 Rockwell Int’l Corp. et al. Rockwell Int’l Corp. et al. could not say with certainty that Eaton was the source of the ignoring the evidence of PCB contamination by Clark, PCBs in the wastewater ditch. Yet, the district court rested its Benteler, and Consumers Power, we are not left with the firm decision on Connolly’s testimony and ruled that it was and definite conviction that the district court committed a unlikely that Eaton’s PCBs added to the pollution in the mistake. Connolly’s testimony about the lack of a gradient Morrow Lake Dam and even less likely that these PCBs then flowing downstream from Eaton and the concentration of entered the NPL site. If Eaton did release any PCBs, it PCBs at the downstream, rather than the upstream border of released an extremely minimal volume to the RI/FS zone such Morrow Lake, as well as the dearth of evidence that Eaton that Eaton was responsible for only a small share of KRSG’s even used PCBs in significant quantities at any point in its costs. operation, all help bolster the district court’s allocation order. Furthermore, the court did not myopically base its decision on KRSG’s failure to rule out Clark and Benteler as potential PCB sources. Whereas KRSG views the district court as requiring it to disprove other parties’ potential responsibility, the district court in reality recognized that some convincing evidence demonstrated that parties other than Eaton may have been the chief polluters of the wastewater ditch, Morrow Lake, and the NPL site. It accordingly held that Eaton was liability phase, see J.A. II at 382 -83 (D ist. Ct. Op . 5/9/01), that C lark did responsible for only a small portion of KRSG’s costs, because not discharge any e ffluent to the ditch it shared with Eaton, because the evidence showed that Clark contributed to the PCB district cou rt held that this earlier finding was based upon the erroneous testimony of Thomas Mattson, who mistakenly claimed that Clark did not contamination in the discharge ditch and that Benteler discharge any PCB-containing effluent to the shared ditch.

Aroclors 1254 and 1260 at Morrow Lake.7 Yet, even KRSG also complains about an alleged inconsistency between previous findings and the district court’s holding that facilities closer to Morrow Lake were in fact the most likely source of the Aroclor 1254 and 7 1260 pollution at Mo rrow Lake.

The district court did not exonerate Benteler. opposite, the district court noted that Clark may have been responsible for Rather, it granted the motion for summary judgment because KRSG did some PCB contamination.

The district judge cautioned that ago; i.e., some convincing facts that the Morrow Lake contaminatio n did “no direct evidence” showed that Clark’s discharges contained PCBs, but not come from sources upstream of Morrow Lake, but rather came from he mentio ned that Clark may have used P CB -containing oils in its facilities on the lake. This is not an inconsistency, but rather it is the transformers and hydraulic systems. J.A. II at 437 . Furthermore, there is reality that Eaton is using evidence against KRSG that would have helped no inconsistency with the district court’s previous finding during the KRS G in its case against Benteler. Nos. 01-2453;02-2192 Kalamazoo River v. 31 Rockwell Int’l Corp. et al. IV. CONCLUSION Because the district court correctly dismissed KRSG’s motion to reopen as a Rule 60(b)(2) motion that was time- barred and because the district court did not commit clear error or abuse its discretion in allocating to Eaton only a very small portion of KRSG’s investigation costs, we AFFIRM the decisions of the lower court.
