TESTIMONY AND OPINIONS OF DR. B. TOD DELANEY (DOC.
#999)
This matter is currently before the Court on three motions in limine: (1)
Waste Management of Ohio, Inc.’s Motion in Limine to Exclude Declaration of
Stephen M. Quigley, Doc. #986; (2) ConAgra Grocery Products Company, LLC’s
Motion in Limine to Exclude Certain Expert Testimony of Dr. Jurgen Exner, Doc.
#998; and (3) Plaintiffs’ Motion in Limine to Exclude Certain Testimony and
Opinions of Dr. B. Tod Delaney, Doc. #999. ConAgra has also filed a Rule 56(c)(2)
Objection to Dr. Exner’s Declaration, Doc. #981, raising arguments similar to those
raised in its Motion in Limine.
Factual Background
Plaintiffs, Hobart Corporation, Kelsey-Hayes Company and NCR Corporation,
filed suit against numerous defendants under the Comprehensive Environmental
Response, Compensation and Liability Act of 1980 (“CERCLA”), as amended, 42
U.S.C. § 9601, et seq., seeking contribution for response costs incurred in
connection with the South Dayton Dump and Landfill Site (“the Site”).
Two of those Defendants, Waste Management of Ohio, Inc. (“WMO”), and
ConAgra Grocery Products Company, LLC (“ConAgra”), have filed motions in
limine asking the Court to exclude, from consideration on the pending summary
judgment motions and at trial, certain expert witness testimony of Stephen M.
Quigley and Dr. Jurgen Exner. Plaintiffs have also filed a motion in limine, asking
the Court to exclude, both from consideration on summary judgment and at trial,
certain testimony and opinions of Con Agra’s expert witness, Dr. B. Tod Delaney.
ll. Motions in Limine
Although neither the Federal Rules of Evidence nor the Federal Rules of Civil
Procedure explicitly authorizes the Court to rule on an evidentiary motion in limine,
the Supreme Court has noted that the practice of ruling on such motions “has
developed pursuant to the district court's inherent authority to manage the course
of trials.” Luce v. United States, 469 U.S. 38, 41 n.4 (1984). The purpose of a
motion in limine is to allow the Court to rule on issues pertaining to evidence in
advance of trial in order to both avoid delay and ensure an evenhanded and
expeditious trial. See /ndiana Ins. Co. v. Gen. Elec. Co., 326 F. Supp.2d 844, 846
(N.D. Ohio 2004) (citing Jonasson v. Lutheran Child & Family Servs., 115 F.3d
436, 440 (7th Cir. 1997)). Also, pretrial orders often save the parties time and
costs in preparing for trial and presenting their cases.
Courts are generally reluctant to grant broad exclusions of evidence in
limine, however, because “a court is almost always better situated during the
actual trial to assess the value and utility of evidence.” Koch v. Koch Indus., Inc.,
2 F. Supp.2d 1385, 1388 (D. Kan. 1998); accord Sperberg v. Goodyear Tire &
Rubber Co., 519 F.2d 708, 712 (6th Cir. 1975). A court should not make a ruling
in limine unless the moving party meets its burden of showing that the evidence in
question is clearly inadmissible. /ndiana Ins. Co., 326 F. Supp.2d at 846; Koch, 2
F. Supp.2d at 1388. If this high standard is not met, evidentiary rulings should be
deferred so that the issues may be resolved in the context of the trial. /nd/ana /ns.
Co., 326 F. Supp.2d at 846.
Ill. Waste Management of Ohio, Inc.’s Motion in Limine to Exclude Declaration
of Stephen M. Quigley (Doc. #986)
Stephen M. Quigley, of the environmental consulting firm GHD, oversees the
vapor intrusion (“VI") mitigation work plan at the South Dayton Dump and Landfill
Site. Plaintiffs designated Quigley as a lay witness who would testify about “Work
performed in VI and [Remedial Investigation/Feasibility Study]; consistency with
[National Contingency Plan]; releases at Site; [and] connection between releases
and incurrence of response costs.” Doc. #1038-1, PagelD#40208.
Plaintiffs also designated Quigley as an expert witness with respect to costs
incurred at the Site. In July of 2017, Quigley submitted a Memorandum
concerning past and future anticipated costs of vapor intrusion work activities.
Doc. #986-3, PagelD##37586-92. He submitted a supplemental report in July of
2018. Doc. #986-4, PagelD##37594-600.
When Quigley was deposed on September 6, 2018, he was questioned by
several Defendants about the methane gas found at the Site. He noted that they
had not been able to isolate the source of the methane. When asked whether,
based on his experience, he had an opinion on the source of the methane, he
responded “[t]he methane is coming from either the decomposition of some
organic material, be it wood or something else that’s been disposed of at the site,
or it’s coming from the degradation of other organics, organic solvents, it’s not
clear.” Doc. #1038-3, PagelD##40270-71.
Plaintiffs attached a December 20, 2018, Declaration of Stephen M.
Quigley, Doc. #986-1, PagelD##37539-43, to their Responses in Opposition to
WMO's Motion for Summary Judgment on behalf of Industrial Waste Disposal Co.,
Inc., Doc. #912-42, and WMO’s Motion for Summary Judgment on behalf of
Blaylock Trucking Company, Inc., Docs. #935-13.
In paragraphs 9 through 11 of his Declaration, Quigley notes that, as set
forth in the 2013 Administrative Settlement Agreement and Order on Consent
(“ASAOC”"), the United States Environmental Protection Agency (“EPA”) found that
vapor intrusion mitigation was necessary based on chlorinated volatile organic
compounds (“CVOCs"), primarily TCE, found in thirteen buildings at the Site, and
on “methane in sub-slab samples at concentrations greater than the Lower
Explosive Limit (LEL) in 2 buildings and in samples collected from an off-Site well.”
Quigley further states that methane was “one of the original drivers of EPA’s vapor
intrusion removal action at the Site.” Doc. #986-1, PagelD#37541.
In paragraph 12 of his Declaration, Quigley states:
As | stated in my deposition in this case on September 6, 2018, in
response to questioning by counsel for one of the defendants, the
sources of methane at the Site come from the decomposition of
organic material, such as wood or other materials disposed at the
Site, such as organic solvents. In addition to wood and solvents,
methane gas at landfills can be produced by organic wastes
including food, garden waste, street sweepings, textiles, cardboard,
newspaper and other paper products. See ATSDR, Landfill Gas

www.atsdr.cdc.gov/hac/landfill/pdfs/landfill 2001 ch2mod.pdf

Mines, Johnson, G.E. et al, The Production of Methane by the

Id. at PagelD#37542. The documents cited in this paragraph were attached to
Quigley’s Declaration.
WMO has moved to exclude Quigley’s Declaration and the supporting
documents from trial, and from consideration on pending summary judgment
motions. WMO also asks that Quigley be prohibited from testifying at trial
concerning this Declaration. WMO argues that the Declaration should be excluded
under Fed. R. Civ. P. 37(c)(1) because: it is completely unrelated to Quigley’s
previous expert opinions, which were limited to the topic of the costs of vapor
intrusion mitigation activities; it was filed after the close of discovery; and it fails
to comply with the expert witness disclosure requirements of Fed. R. Civ. P.
26(a)(2).
Supplementation of a Rule 26 disclosure is warranted “if the party learns
that in some material respect the disclosure . . . is incomplete or incorrect.” Fed.
R. Civ. P. 26(e). However, Quigley’s previous reports on the costs of vapor
intrusion mitigation at the Site are not alleged to be incomplete or incorrect. WMO
maintains that the Declaration is an improper supplement to Quigley’s previous
expert reports, because it adds new opinions about the risks and sources of
methane at the Site, topics on which Plaintiffs have never designated Quigley as
an expert.
Although Quigley was questioned at his deposition about sources of
methane at the Site, WMO argues that this does not authorize him to offer new
"Fed. R. Civ. P. 37(c)(1) provides that “[i]f a party fails to provide information
... as required by Rule 26(a) or (e), the party is not allowed to use that
information . . . to supply evidence on a motion, at a hearing, or at a trial, unless
the failure was substantially justified or is harmless.”
expert opinions on this subject after the close of discovery. Deposition testimony
may form the basis for a supplemental report only if it is directly related to the
opinions in the expert witness report. See Lexington Ins. Co. v. Horace Mann Ins.
Co., No. 11C2352, 2015 WL 5174159, at **9-10 (N.D. Ill. Aug. 27, 2015)
(rejecting attempt to “supplement” expert witness report with new opinions
introduced at deposition). WMO argues that consideration of Quigley’s new
opinions would be unfair because WMO has not had the opportunity to cross-
examine him about his new Declaration or the supporting documents.
In response, Plaintiffs first note that WMO has actually objected to only a
portion of Quigley’s declaration, more specifically paragraphs 9-12.? Plaintiffs
argue that Quigley’s Declaration is “not a supplement to his expert report, but
rather a factual Declaration based on personal knowledge.” Doc. #1038,
PagelD#40184. The Court agrees with respect to paragraphs 9 through 11,
wherein Quigley simply recounts the EPA’s factual findings concerning methane
and vapor intrusion at the Site, as set forth in the ASAOC.
Paragraph 12, however, is different. Quigley therein opines about the
possible sources of methane gas at the Site, stating that the gas comes from the
decomposition of organic material. Plaintiffs maintain that these statements are
based on his experience doing technical work at landfill cleanups, and are
* Others portions of Quigley’s Declaration discuss his role as the project
coordinator, groundwater flow at the Site, and Defendant Valley Asphalt’s
Reclaimed Asphalt Pavement Pile.
consistent with his role as a fact witness testifying about releases at the Site and
the connection between those releases and the incurrence of response costs.
Nevertheless, as WMO notes, at his deposition, Quigley was asked if he had
“any opinions as to what you think might be generating the methane at this site.”
Doc. #1083-3, PagelD#40271 (emphasis added). Paragraph 12 of the Declaration
specifically refers back to his answer to this question. Moreover, Quigley’s
statements about sources of methane gas at the Site are beyond the understanding
of the average person. Rather, they are based on “scientific, technical, or other
specialized knowledge,” taking them outside the scope of lay witness testimony.
See Fed. R. Evid. 701. The Court therefore finds that paragraph 12 of Quigley’s
Declaration is more properly characterized as an expert opinion. See United States
v. Beierle, 810 F.3d 1193, 1203 (10th Cir. 2016) (“Knowledge derived from
previous professional experience falls squarely within the scope of Rule 702 and
thus by definition outside of Rule 701.”) (internal quotations omitted)
Plaintiffs maintain that, even if paragraph 12 is considered an expert opinion,
it is permissible because it builds on his deposition testimony on the same subject.
In support of this argument, Plaintiffs cite to Great Northern Insurance Co. v. BMW
of North America LLC, No. 2:11-cv-1153, 2015 U.S. Dist. LEXIS 83240 (S.D.
Ohio June 26, 2015). Therein, the court held that an expert witness could testify
at trial about deposition statements made in response to certain photographs that
were shown to him. /d. at *25. That deposition testimony, however, was directly
related to the opinions already contained in his expert witness report.
Here, in contrast, Mr. Quigley was presented as an expert witness on costs,
not on the causes of methane. His deposition testimony about sources of methane
at the Site falls outside the scope of his expert witness opinions on the cost of
vapor intrusion mitigation. The Court agrees with WMO that allowing Quigley to
offer a new expert witness opinion concerning the causes of methane at the Site
after the close of expert discovery would be unfair to WMO, which has not had the
opportunity to challenge these new opinions.°
Accordingly, under Fed. R. Civ. P. 37(c)(1), paragraph 12 of Quigley’s
Declaration, and the documents cited therein, must be excluded from trial and will
not be considered in ruling on the motions for summary judgment. Neither will
Quigley be permitted to testify about the sources of methane at the Site. As WMO
notes, Plaintiffs will not be prejudiced by the exclusion of this portion of Quigley’s
Declaration, given that they have retained Dr. Jurgen Exner to testify about
methane and toxicity issues.
For the reasons set forth above, the SUSTAINS IN PART and OVERRULES IN
PART WMO’'s Motion in Limine to Exclude Declaration of Stephen M. Quigley, Doc.
#986. Only paragraph 12 of the Declaration is excludable; the remainder is
admissible.
° Given that all of the motions for summary judgment are fully briefed, allowing
Quigley to be re-deposed at this late date is not a viable option.
IV. | Conagra Grocery Products Company, LLC’s Motion in Limine to Exclude
Certain Expert Testimony of Dr. Jurgen Exner (Doc. #998) and Rule 56(c)(2)
Objection to Exhibit 1 to Plaintiffs’ Sur-reply (Doc. #981)
Defendant ConAgra Grocery Products Company (“ConAgra”) is the
successor-in-interest to the McCall Printing Company (“McCall”). ConAgra has
moved for summary judgment, Doc. #874, arguing, in part, that Plaintiffs’ expert
witness, Dr. Jurgen Exner, testified at his deposition that he had no evidence that
McCall sent any substances containing chlorinated solvents to the Site. Doc.
#874-13, PagelD#25869.
In their Corrected Response to ConAgra’s motion for summary judgment,
filed on December 23, 2018, Plaintiffs noted that they had recently discovered a
Health Hazard Evaluation Determination, authored in 1975 by the National Institute
for Occupational Safety and Health (“NIOSH”), indicating that McCall used
kerosene and an unknown solvent named Ottoson No. 9 to clean equipment, and
that TCE was used to soften the glue used in splicing paper. Doc. #917-7,
PagelD#33717.*
Attached to ConAgra’s Reply Memorandum was a Declaration of ConAgra’s
expert witness, Dr. B. Todd Delaney, dated January 9, 2019. Doc. #957-1,
PagelD##37111-12. In response to the recently-discovered NIOSH report, Dr.
Delaney states that nothing in that report supports an assertion that McCall
disposed of TCE. He stated that “TCE is very volatile and evaporates quickly.” To
* Plaintiffs do not allege that ConAgra intentionally withheld this report.
10
the extent that the NIOSH report indicates that TCE was sprayed on the printer
rollers in short intervals, Delaney opines that it either ended up on the roller or
evaporated almost immediately. No waste containing TCE would have been
generated. /d.
Thereafter, Plaintiffs were granted leave to file a Sur-reply to address Dr.
Delaney’s Declaration. Attached to that Sur-reply was a January 22, 2019,
Declaration of Jurgen Exner, Ph.D., Doc. #975-1, PagelD##37410-11. In that
Declaration, Dr. Exner noted that he was not aware of the NIOSH report when he
had issued his previous expert reports. He now opined that it was “highly likely
that TCE waste was generated from cleanup of spills, leaks, cleanout of process
equipment, and disposal of TCE-containing containers.” He also opined that it was
“highly likely that TCE-containing waste and containers were disposed of by
McCall.” He disagreed with Dr. Delaney’s opinion that all of the TCE evaporated.
Id.
On February 14, 2019, ConAgra filed a Rule 56(c)(2) Objection to Dr.
Exner’s Declaration, arguing that it was untimely and prejudicial and should be
disregarded. Doc. #981. This was followed by ConAgra’s Motion in Limine to
Exclude Certain Expert Testimony of Dr. Jurgen Exner. Doc. #998. Again,
ConAgra asks the Court to prevent Dr. Exner from presenting any opinions
contained in his January 22, 2019, Declaration, which was submitted after the
expert disclosure and deposition deadlines. ConAgra seeks to restrict his
testimony to opinions offered in his July 13, 2017, and July 24, 2018, reports as
1]
limited by his deposition testimony. ConAgra argues that not only is Dr. Exner’s
January 22, 2019, Declaration untimely, unsupported, and inconsistent with his
prior deposition testimony, but it is also prejudicial in that ConAgra has not had the
opportunity to depose Dr. Exner on this topic. For these reasons, ConAgra urges
the Court to disregard Dr. Exner’s Declaration, and to exclude Dr. Exner’s new
opinions under Fed. R. Civ. P. 26(a)(2)(D) and Fed. R. Civ. P. 37(c)(1).
In response, Plaintiffs note that Dr. Delaney’s and Dr. Exner’s Declarations
were both filed beyond the established deadlines. However, this is attributable
solely to the fact that the NIOSH report was not discovered by Plaintiffs until late
November of 2018, after the close of discovery. The Court finds that, because the
failure to timely produce these supplemental witness opinions was “substantially
justified,” Fed. R. Civ. P. 37(c)(1) does not bar their consideration either at trial or
in connection with the pending motions for summary judgment.’
Moreover, this result is not unfair to either party. The expert witnesses of
both parties have already stated their opinions on the impact of the NIOSH report.
In addition, Plaintiffs have indicated that they do not object to conducting brief,
supplemental depositions of Dr. Exner and Dr. Delaney limited in scope to their
supplemental opinions related to that report. Should either party wish to pursue
> In its Reply brief, ConAgra argues that Plaintiffs’ response to the Rule 56(c)(2)
Objection is untimely. Given that ConAgra raised the same arguments in the
motion in limine that were raised in the Rule 56(c)(2) Objection, and given that
Plaintiffs’ response to the motion in limine was timely filed (following the Court's
May 22, 2019, conference call), the Court need not address this issue.
12
this option, the Court will entertain a motion for leave to do so. Any such motion
must be filed within 15 days of the date of this Decision and Entry.
For the reasons stated above, the Court OVERRULES ConAgra’s Rule
56(c)(2) Objection to Exhibit 1 of Plaintiffs’ Sur-reply, Doc. #981, and its Motion in
Limine to Exclude Certain Expert Testimony of Dr. Jurgen Exner, Doc. #998. The
Court will consider Dr. Exner’s belated Declarations in ruling on the pending
motions for summary judgment and he may testify about his opinions at trial.°
V. Plaintiffs’ Motion in Limine to Exclude Certain Testimony and Opinions of Dr.
B. Tod Delaney (Doc. #999)
Plaintiffs ask the Court to exclude from trial, and from consideration on
summary judgment, all testimony of ConAgra’s expert witness, Dr. B. Tod
Delaney, related to his assessment of the credibility of witnesses Edward Grillot
and Michael Wendling and his assessment of the trustworthiness of certain
documentary evidence. In addition, Plaintiffs seek to exclude certain opinions
presented in Dr. Delaney’s May 18, 2018, Expert Report and his July 24, 2018,
Rebuttal Report which rely on his personal weighing of the evidence and credibility
assessments. Doc. #999.
As WMO has noted, although the NIOSH report and Dr. Exner’s Declaration may
support a finding that McCall generated waste that contained TCE, neither the
report nor the Declaration supports a finding that McCall disposed of any such
waste at the South Dayton Dump. Evidence of that link would have to come from
elsewhere.
13
At his three depositions, Edward Grillot, whose family owned and operated
the South Dayton Dump, testified about materials that McCall disposed of at the
Site, including ink waste and solvents.’ Michael Wendling, Grillot’s cousin,
testified twice about hazardous waste transported by McCall to the Site, and later
submitted a Declaration concerning this topic. It is undisputed that the testimony
of these two witnesses has been somewhat inconsistent over time.
In his May 18, 2018, Expert Report, Dr. Delaney opined as follows: “Opinion
1. There is a low degree of certainty due to a lack of credible evidence that
McCall arranged for hazardous materials to be disposed of at the Site or that any
such materials generated by McCall were disposed of there.” Doc. #883-1,
PagelD#26495. At his deposition, Dr. Delaney explained that Grillot’s testimony
on this subject was “just not credible.” Doc. #883, PagelD#26419.
In his Report, Delaney noted that Grillot’s testimony was contrary to that of
Horace Boesch, Jr., the son of one of the former owners of the Site, who never
mentioned that McCall’s waste was hauled to the Site. It was also contrary to the
testimony of McCall employee, George Morris, Jr., and of several waste haulers
who denied hauling McCall waste to the Site. Dr. Delaney found that Grillot’s
deposition testimony reflected “uncertainty and confusion.” He further noted that
Grillot’s testimony concerning the nature of McCall's waste and the identity of
"As previously noted, ConAgra is the successor-in-interest to McCall Printing
Company.
14
who brought it to the Site did not remain constant across the course of his three
depositions. Doc. #883-1, PagelD#26495-96.
In his July 24, 2018, Rebuttal Report, Dr. Delaney challenges the opinions
of numerous other expert witnesses in this case. He concludes as follows:
Opinion 1. No expert can make a credible determination that McCall
disposed of hazardous materials at the Site or arranged for the
disposal of such materials there.
Opinion 2. Exner has insufficient information to determine that McCall
arranged for disposal of hazardous substances at the Site.
Opinion 3. Wittenbrink’s conclusions cannot be drawn to a
reasonable degree of scientific certainty.
Opinion 4. Hennet’s conclusion that McCall contributed VOCs to the
Site is unsupported by the evidence, and his allocation for McCall is
therefore flawed.
Opinion 5. White presents a reasonable preliminary framework, but
its immediate utility is limited because . . . the calculated waste
volume for McCall is founded on unreliable testimony.
Doc. #883-2, PagelD##26532-52. Dr. Delaney opines that, in reaching their
conclusions, Exner, Wittenbrink, Hennet and White relied on witness testimony
that was not supported by credible evidence, /.e., that of Grillot and Wendling.
Plaintiffs concede that the deposition testimony and Declarations of Grillot
and Wendling are inconsistent, and are contrary to the testimony of several other
witnesses. Plaintiffs argue, however, that these inconsistencies must be resolved
by the finder of fact, not by Dr. Delaney. Plaintiffs note that Delaney is not
qualified under Fed. R. Evid. 702 to opine on matters of credibility. Citing Davis v.
Duran, 277 F.R.D. 362, 370 (N.D. Ill. 2011), Plaintiffs further argue that Dr.
Delaney has improperly usurped the duty of the factfinder to weigh the evidence
and make credibility determinations. In addition, they argue that Delaney’s
15
credibility determinations are flawed in numerous respects. Plaintiffs therefore ask
the Court to exclude Dr. Delaney’s opinions and any testimony about his views on
the credibility of Grillot and Wendling.
In its Memorandum in Opposition to Plaintiffs’ Motion in Limine, ConAgra
agrees with Plaintiffs that it is improper for expert witnesses to make credibility
determinations. It argues, however, that Plaintiffs have mischaracterized Dr.
Delaney'’s opinions. According to ConAgra, Dr. Delaney did not make subjective
credibility determinations. Instead, most of his opinions “are rooted in the premise
that an expert cannot offer an opinion with any degree of scientific certainty if it
requires him/her to reconcile inconsistent witness testimony and make credibility
determinations.” Doc. #1039, PagelD#40275. ConAgra argues that, given the
conflicting witness testimony in this case, Delaney simply concludes that no expert
can opine with any degree of scientific certainty that McCall sent hazardous
material to the Site. ConAgra therefore argues that there is no reason to exclude
Dr. Delaney’s testimony or opinions.
The Court disagrees. It is clearly established that expert witness testimony
concerning the credibility of a fact witness is improper. Greenwell v. Boatwright,
184 F.3d 492, 496 (6th Cir. 1999) (holding that expert witness testimony
regarding credibility of eyewitness testimony is improper); MAA Oil Co. v. Korpan,
973 F. Supp. 2d 775, 787 (N.D. Ohio 2013) (holding that an expert report that
comments on the credibility of witnesses is improper); United States v. Scop, 846
F.2d 135, 142 (2d Cir. 1988) (finding that expert witnesses may not offer their
16
opinions “based on their personal assessment of the credibility of another
witness's testimony”). As the Tenth Circuit has explained:
Such testimony: (1) usurps a critical function of the jury; (2) is not
helpful to the jury, which can make its own determination of
credibility; and (3) when provided by impressively qualified experts on
the credibility of other witnesses is prejudicial and unduly influences
the jury.
United States v. Hill, 749 F.3d 1250, 1258 (10th Cir. 2014) (internal quotations
omitted). Moreover, such testimony “exceeds the scope of the expert's
specialized knowledge and therefore merely informs the jury that it should reach a
particular conclusion.” United States v. Shay, 57 F.3d 126, 131 (1st Cir. 1995).
Many of Dr. Delaney’s expert witness opinions are based on his personal
assessment of the credibility of Plaintiffs’ lay witnesses Grillot and Wendling. In
some cases, this is blatant, such as Opinion 1 in the May 18, 2018, Report
wherein he opines that “[t]here is a low degree of certainty due to a lack of
credible evidence” concerning McCall's alleged disposal of hazardous waste at the
Site, Doc. #883-1, PagelD#26495, and Opinion 5 in his July 24, 2018, Rebuttal
Report wherein he challenges Richard White’s expert opinion on the grounds that
“the calculated waste volume for McCall is founded on unreliable testimony.” Doc.
#883-2, PagelD#26548.
Likewise, Opinion 1 in the Rebuttal Report is based on Delaney’s personal
assessment that the other experts’ determinations that McCall’s waste was hauled
to the Site “are unsupported by any credible evidence,” and Opinion 3 is based on
his assessment that “Wittenbrink’s opinion that McCall self-hauled waste is based
IZ
on unreliable testimony.” /d. at PagelD ##26538, 26541. Opinion 2 faults Dr.
Exner for relying on “inconsistent” testimony of Edward Grillot and Michael
Wendling. On this basis, Delaney concludes that “Exner has insufficient
information to make a credible determination that McCall actually disposed or
arranged for the disposal of hazardous substances at the Site.” /d. at
PagelD##26539-40.
Of course, at trial, the fact witnesses will be cross-examined about the
inconsistencies in their testimony. Likewise, ConAgra and the other defendants
will almost certainly subject these expert witnesses to cross-examination about the
facts on which their opinions are based. To the extent that their opinions are
based on the testimony of witnesses whose credibility has been called into
question, that will no doubt be brought to light, possibly undermining the weight to
be given their expert opinions. See Fed. R. Evid. 705 (although an expert may
state an opinion without disclosing facts or underlying data, the expert may be
required to disclose those on cross-examination).
Nevertheless, the Court agrees with Plaintiffs that it is improper for Dr.
Delaney to offer an expert witness opinion about the credibility of fact witnesses.
Accordingly, Dr. Delaney will not be permitted to testify concerning his assessment
of the credibility of witnesses Edward Grillot or Michael Wendling. Likewise, to the
extent that Opinion 1 in the May 18, 2018, Expert Report, and Opinions 1, 2, 3
and 5 in the July 24, 2018, Rebuttal Report rely on Dr. Delaney’s personal
18
weighing of the evidence and credibility assessments, the Court will exclude those
Opinions from consideration on summary judgment and at trial. ®
Plaintiffs also seek to exclude Dr. Delaney’s testimony concerning the
trustworthiness of certain documentary evidence. At Dr. Delaney’s deposition,
Plaintiffs presented him with Building and Zoning Permits, and Applications for
Refuse Disposal Permits, filed between 1967 and 1972, in which the Site’s owner
repeatedly includes McCall on a list of sources of waste deposited at the Site.
Doc. #883-3, PagelD##26569-602. Dr. Delaney testified that, if there were other
credible evidence to corroborate a finding that waste from McCall was actually
deposited at the Site, he might find these permits and applications to be credible
also. However, because there was no credible corroborating evidence, he
speculated that these permits and applications may contain lists of potential
customers rather than actual customers. Doc. #883, PagelD##26412-13. To the
extent that Dr. Delaney’s opinion concerning the trustworthiness of these permits
and applications again hinges on his assessment of the credibility of witnesses
Grillot and Wendling, the Court will exclude it for the reasons set forth above.
As ConAgra points out, it is not entirely clear which of the five Opinions
contained in the July 24, 2018, Rebuttal Report Plaintiffs seek to exclude. At one
point in the Motion in Limine, Plaintiffs reference Opinions 2, 3, and 5; at another
point, they reference Opinions 1, 2, and 5. Doc. #999, PagelD##38392, 38394.
In an abundance of caution, ConAgra’s Response covers Rebuttal Opinions 1, 2, 3
and 5. In their Reply brief, Plaintiffs also ask the Court to exclude Opinion 4. Doc.
#1047, PagelD#40382. Because this is a new argument, to which ConAgra has
not had the opportunity to respond, the Court makes no determination as to
whether Opinion 4 should be barred from consideration.

Another form submitted to the Ohio EPA in 1981 in connection with a
permit application by Dayton Press Company, which purchased the McCall plant
from ConAgra in the mid-1970s, estimates that the plant generates 4000 pounds
per year of spent halogenated solvents used in degreasing, which would include
TCE. Doc. #883-14, PagelD#26719; Doc. #883-15, PagelD#26723. Dr. Delaney
testified that, after the purchase of the plant, Dayton Press made few changes to
McCall's operations. Plaintiffs maintain that this gives rise to an inference that
McCall generated a like amount of spent halogenated solvents each year. Dr.
Delaney, however, testified that, with respect to the 4000 pounds of spent
halogenated solvents, “Dayton Press made a mistake” on the form because Dayton
Press did not do “degreasing” as that term is properly defined. Doc. #883,
PagelD##26432-33.
Plaintiffs argue that, in so testifying, Dr. Delaney again oversteps his
authority by deciding which parts of this permit application are credible. The Court
rejects this argument. Dr. Delaney testified that, based on his experience in this
industry during this particular period of time, this was a common mistake made by
industry representatives in completing this particular form. /d. Unlike Plaintiffs’
objections to Dr. Delaney’s other expert witness opinions, this one does not
involve a credibility assessment. Rather, it is an opinion based directly on his
specialized knowledge and experience in this industry. The Court therefore
concludes that Dr. Delaney may testify about why the statements contained in the
20
1981 Ohio EPA form do not support a finding that McCall generated that amount
of spent halogenated solvents.
In accordance with the foregoing, the Court SUSTAINS IN PART and
OVERRULES IN PART Plaintiffs’ Motion in Limine to Exclude Certain Testimony and
Opinions of Dr. B. Tod Delaney, Doc. #999.
Vi. Conclusion
