CIVIL ACTION NO. 2:18-CV-48-KS-MTP

THE TRAVELERS INDEMNITY
COMPANY OF AMERICA

DEFENDANT

MEMORANDUM OPINION AND ORDER
For the reasons provided below, the Court grants in part and denies in part
Travelers’ Motion to Strike [124] an affidavit from Plaintiff’s expert, Dr. Fernando
Lorenzo, and the Court grants in part and denies in part Travelers’ Motion to
Exclude [105] the testimony of Plaintiff’s expert, Dr. Fernando Lorenzo.
I. BACKGROUND
This is an insurance coverage dispute arising from a hydrochloric acid (“HCl”)
spill. On October 14, 2016, approximately 5,300 gallons of HCl leaked from a storage
tank on property adjacent to that owned by Plaintiff, Burroughs Diesel, Inc. Plaintiff
alleges that the spill created a cloud of HCl vapor that traveled to and engulfed its
property for hours, causing extensive damage to buildings, vehicles, inventory, tools,
machines, and equipment.
At the time of the spill, Plaintiff was insured under a property insurance policy
issued by Defendant, Travelers Indemnity Company of America. Plaintiff filed a
claim shortly after the spill. On October 26, 2016, Travelers’ engineer investigated

the damage to Plaintiff’s facilities and property. One week later, the adjuster sent
Plaintiff an e-mail denying the claim, citing the policy’s pollution exclusion. Over the
next year or so, Plaintiff continued to request that Travelers pay the claim, and
Travelers continued to deny it.
Plaintiff filed this suit against Travelers, claiming that Travelers wrongfully
denied coverage, and that it failed to fully and timely investigate the claim. Plaintiff
asserted the following claims: breach of contract, breach of the duty of good faith and
fair dealing, and tortious breach of contract. Plaintiff seeks an award of benefits
under the policy, punitive damages, attorney’s fees, and interest. Travelers filed two
evidentiary motions, which the Court now addresses.
II. MOTION TO STRIKE AFFIDAVIT [124]
Travelers filed a Motion to Strike [124] an affidavit [116-4] from Plaintiff’s
expert, Dr. Fernando Lorenzo, presented in support of Plaintiff’s response [116] to
Traveler’s Motion to Exclude [105] the testimony of Plaintiff’s experts. Although
Travelers contends that the entire affidavit constitutes new, previously undisclosed
expert testimony, it only addressed several specific topics from the document.
A.

Side Panels’ Loss of Useful Life
First, Travelers contends that Lorenzo articulated a new basis for his opinion

that the painted side panels on Plaintiff’s metal buildings had lost 50% of their useful
life. In the affidavit, he stated:
It is also my opinion that 50% of the protective baked-on enamel painted
coating on the steel side panels of the 10 buildings was reduced due to
2

the acid exposure. The baked-on enamel paint is recognized as providing
corrosion protection by the Majestic Steel publication . . . , but is less
resilient to corrosion than galvanized zinc coatings. As explained in my
deposition . . . , my original 50% metal reduction calculation (with a
thicker coating) reasonably reflects the estimated 50% amount of paint
loss in the protective enamel paint coatings on the side panels.
Exhibit 4 to Response at 4-5, Burroughs Diesel, Inc. v. Travelers Ind. Co. of Am., No.
2:18-CV-48-KS-MTP (S.D. Miss. July 19, 2019), ECF No. 116-4. Lorenzo cited two
PDL Handbooks in support of this opinion. Id. at 5 n. 1.
During his deposition, Lorenzo also testified that 50% of the paint on the metal
buildings’ side panels had been corroded. Exhibit BB to Motion for Summary
Judgment at 48, Burroughs Diesel, Inc. v. Travelers Ind. Co. of Am., No. 2:18-CV-48KS-MTP (S.D. Miss. June 17, 2019), ECF No. 108-28. When directly asked, Lorenzo
stated that the only basis for this opinion was an article from a do-it-yourself home
repair website. Id. at 48-49. When discussing the paint on the side panels, he made
no mention of a Majestic Steel publication or PDL Handbooks. Therefore, the Court
concludes that Lorenzo’s citation of these sources as support for his opinion regarding
the loss of useful life in the metal buildings’ side panels is new testimony, previously
undisclosed.
Rule 26 provides that “a party must disclose to the other parties the identity
of any witness it may use at trial to present” expert testimony. FED. R. CIV. P.
26(a)(2)(A). “Unless otherwise stipulated or ordered by the court, this disclosure must
be accompanied by a written report – prepared and signed by the witness – if the
witness is one retained or specially employed to provide expert testimony in the case
3

. . . .” FED. R. CIV. P. 26(a)(2)(B). “A party must make these disclosures at the times
and in the sequence that the court orders.” FED. R. CIV. P. 26(a)(2)(D). Local Rule 26
provides that a “party must make full and complete disclosure as required by Fed. R.
Civ. P. 26(a) and L.U.Civ.R. 26(a)(2)(D) no later than the time specified in the case
management order.” L.U.Civ.R. 26(a)(2).
Additionally, “[t]he parties must supplement these disclosures when required
under Rule 26(e).” FED. R. CIV. P. 26(a)(2)(E). “[A] party is required to supplement its
expert disclosures if the court so orders or if the party learns that in some material
respect the information disclosed is incomplete or incorrect and if the additional or
corrective information has not otherwise been made known to the other parties
during the discovery process or in writing.” Sierra Club, Lone Star Chapter v. Cedar
Point Oil Co., Inc., 73 F.3d 546, 570 n. 42 (5th Cir. 1996) (quoting FED. R. CIV. P.
26(e)(1)). “[T]he party’s duty to supplement extends both to information included in
the report and to information given during the expert’s deposition. Any additions or
changes to this information must be disclosed by the time the party’s pretrial
disclosures under Rule 26(a)(3) are due.” FED. R. CIV. P. 26(e)(2). “Unless the court
orders otherwise,” pretrial disclosures must be made at least thirty days before trial.@
FED. R. CIV. P. 26(a)(3). Local Rule 26 provides that a “party is under a duty to
supplement disclosures at appropriate intervals under Fed. R. Civ. P. 26(e) and in no
event later than the discovery deadline established by the case management order.”
L.U.Civ.R. 26(a)(5) (emphasis added).
4

Therefore, if Plaintiff wanted to supplement the information provided in
Lorenzo’s expert report and deposition, it was required to do so by the discovery
deadline of May 31, 2019. See Amended Case Management Order, Burroughs Diesel,
Inc. v. Travelers Ind. Co. of Am., No. 2:18-CV-48-KS-MTP (S.D. Miss. Nov. 8, 2018),
ECF No. 37. Here, Plaintiff first disclosed Lorenzo’s reliance on the Majestic Steel
publication and PDL Handbooks to support his opinion regarding the side panels’ loss
of useful life on July 19, 2019, in response to Travelers’ motion to exclude Lorenzo’s
testimony. See Response to Motion to Exclude, Burroughs Diesel, Inc. v. Travelers
Ind. Co. of Am., No. 2:18-CV-48-KS-MTP (S.D. Miss. July 19, 2019), ECF No. 116.
Therefore, the new testimony was not timely disclosed.
Rule 37 provides: “If a party fails to provide information or identify a witness
as required by Rule 26(a) or (e), the party is not allowed to use that information or
witness to supply evidence on a motion, at a hearing, or at trial, unless the failure
was substantially justified or is harmless.” FED. R. CIV. P. 37(c)(1). When determining
whether to strike an expert’s testimony for a party’s failure to timely disclose it, the
Court considers the following factors:
(1)

the importance of the witnesses’ testimony;

(2)

the prejudice to the opposing party of allowing the witnesses to testify;

(3)

the possibility of curing such prejudice by a continuance; and

(4)

the explanation, if any, for the party’s failure to comply with the
discovery order.

Sierra Club, 73 F.3d at 572; see also Reliance Ins. Co. v. La. Land & Exploration Co.,
5

110 F.3d 253, 257 (5th Cir. 1997).
The Court will assume that the proposed testimony is important, but admitting
it at this late stage of the case would be prejudicial to Travelers. Lorenzo cited the
additional sources in response to Travelers’ motion to exclude his testimony for,
among other purported reasons, lack of support. Travelers has not had a chance to
cross-examine Lorenzo concerning the new sources, to investigate them before filing
its dispositive motions, or to acquire a rebuttal opinion from its own expert. There is
no time to cure the prejudice, because the pretrial conference is imminent. Finally,
Plaintiff has not provided any explanation for its failure to timely disclose these
sources.
Therefore, the Court concludes that Lorenzo’s late citation of these additional
sources in support of his opinions regarding the side panels’ loss of useful life should
be excluded. The Court strikes sub-paragraph (C) of Section 3 of Lorenzo’s affidavit.
See Exhibit 4 [116-4], at 4-5. Plaintiff is not allowed to rely on this evidence or
testimony in support of or response to a motion, at a hearing, or at trial.
B.

Total Loss of Remaining Useful Life
Next, Travelers argues that Lorenzo asserted a new opinion regarding the total

loss of remaining useful life for Plaintiff’s metal buildings. In the affidavit, Lorenzo
stated:
As described herein, after and as a result of the acid exposure at issue,
the roof panels lost 80% of its [sic] remaining useful life, and the side
panels lost 50% in its [sic] remaining useful life. Together, there is an
average 65% reduction in useful life, which is proportionate to the
6

reduction in the fair market value of the buildings after the spill. As
such, the diminution in value of the buildings after the spill is 65% of
the pre-spill fair market value . . . .
Id. at 6.
In his initial report, dated March 29, 2019, Lorenzo stated that the roofs and
side panels on the metal buildings had lost 50% of their remaining useful life. Exhibit
CC to Motion for Summary Judgment at 8, Burroughs Diesel, Inc. v. Travelers Ind.
Co. of Am., No. 2:18-CV-48-KS-MTP (S.D. Miss. June 17, 2019), ECF No. 108-29.
Later, during his deposition, he revised his estimate as to the roofs, asserting that
they had lost 80% of their remaining useful life. Exhibit BB [108-28], at 30. Prior to
the affidavit produced in response to Travelers’ motion, Lorenzo never claimed that
the whole buildings had lost 65% of their remaining useful life. Moreover, he never
provided any testimony suggesting that one could or should calculate the buildings’
loss of remaining useful life by splitting the difference between that of the roofs and
side panels. In response, Plaintiff only notes Lorenzo’s testimony regarding the loss
of useful life of the roofs and side panels, rather than that of the buildings as a whole.
Therefore, the Court concludes that Lorenzo’s opinion that the buildings lost 65% of
their remaining useful life is a new opinion that was not timely disclosed.
The Court will assume that the opinion is important, but admitting it at this
late stage of the case would be prejudicial to Travelers. Travelers has not had a
chance to cross-examine Lorenzo concerning the new opinion, or to acquire a rebuttal
opinion from its own expert. There is no time to cure the prejudice, because the
7

pretrial conference is imminent. Finally, Plaintiff has not provided any explanation
for its failure to timely disclose Lorenzo’s opinion regarding the buildings’ loss of
remaining useful life. Therefore, the Court strikes Lorenzo’s opinion that the metal
buildings lost 65% of their remaining useful life. Plaintiff is not allowed to rely on
this evidence or testimony in support of or response to a motion, at a hearing, or at
trial.
C.

Difficulty of Repair
Travelers also argues that the affidavit contains a new opinion regarding the

difficulty of repairing the metal buildings’ side panels, and that repair would produce
an inferior product. In the affidavit, he stated:
During my deposition . . . , I explained that the zinc coatings of the roof
panels are made in the factory through hot-dipped galvanization, and
re-galvanizing the damaged roofing panels, once removed, would
necessitate farming the same out to a qualified third-party capable of
re-applying the galvanizing coating commensurate with the original
finish. Further, any attempted repair of the roof panels with zinc-based
paint will produce an inferior protective coating on the steel that last
[sic] approximately 1/5 to 1/10 as long as a roof panel with galvanized
zinc coating installed during the manufacturing process. There is also
far less adherence or bonding between the zinc paint and steel than the
hot-dipped galvanizing process used in the manufactured panels. Efforts
to remediate the damages incurred to the roofs of BDI’s buildings
necessitate the removal of all metal roofing panels for thorough
cleaning, which would then have to be reinstalled after either regalvanizing or coating with a zinc-based paint solution. Removal and reinstallation of each and all panels would be necessary so as to address
the HCL [sic] contamination beneath each of the overlapping joints upon
the roofs which exacerbate the corrosion process. This process will be
just as costly as removing and installing new galvanized roof panels and
will produce a grossly inferior product that will not provide the intrinsic
cathodic protection obtained from hot dip galvanizing in the original roof
panels.
8

Exhibit 4 [116-4], at 6-7. In contrast, during his deposition, Lorenzo expressed no
opinion that repaired roof panels would be inferior to the originals. In fact, when
asked if re-galvanizing would “eliminate the problem,” he simply answered, “Yes. . . .
But you understand that the galvanizing process for the roof plate is how the
galvanizing is – it’s a process that is made during the protection [sic] of the roof
panels.” Exhibit BB [108-28], at 48.
In response, Plaintiff has not directed the Court to any additional prior
testimony from Lorenzo concerning the feasibility, cost, desirability, or quality of
repaired roof panels. Therefore, the Court concludes that Lorenzo’s opinions on this
topic, recited above, are so far beyond the scope of his previous testimony that they
constitute new opinions that were not timely disclosed.
The Court will assume that Lorenzo’s testimony on this topic is important, but
admitting it at this late stage of the case would be prejudicial to Travelers. Travelers
has not had a chance to cross-examine Lorenzo concerning these opinions, or to
acquire rebuttal testimony from its own expert. There is no time to cure the prejudice,
because the pretrial conference is imminent. Finally, Plaintiff has not provided any
explanation for its failure to timely disclose this testimony. Therefore, the Court
strikes Lorenzo’s opinions regarding the difficulty and desirability of repairing the
metal roofs, as contained in the entirety of Section 5, sub-paragraph (A) of the
affidavit. See Exhibit 4 [116-4], at 6-7. Plaintiff is not allowed to rely on this evidence
or testimony in support of or response to a motion, at a hearing, or at trial.
9

D.

Zinc Coating
Finally, Travelers argues that Lorenzo offered new support for his opinions

regarding the amount of zinc coating corroded from the roofing panels by exposure to
HCl. At his deposition, Lorenzo testified that he did not know the original thickness
of the zinc coating on the roof panels. Exhibit BB [108-28], at 30. He said: “I’m
assuming they were G60. In doing the calculations, I didn’t check exactly what – but
. . . it’s some of the most common galvanized sheets that are sold in the U.S. . . . I
don’t know exactly if they are G60. . . . But I’m using a calculation based on that
number.” Id. In his affidavit, Lorenzo supplemented this testimony. He said: “I have
confirmed with Michael Burroughs that the subject galvanized steel roof panels on
the 10 buildings are ‘G60’ designated panels, which . . . is the common metal roofing
panel used for the subject industrial setting.” Exhibit 4 [116-4], at 4. This is
indisputably a new, previously undisclosed basis for Lorenzo’s opinion regarding the
amount of zinc coating corroded from the roofing panels by exposure to HCl.
Lorenzo’s testimony on this topic is important, in that it provides support for
his opinion regarding the amount of zinc coating lost by exposure to HCl, but Plaintiff
provided no explanation as to why Lorenzo didn’t confirm the assumption and
supplement his testimony during the discovery period. Admitting the testimony
would not be prejudicial to Travelers, in that Lorenzo made all his calculations based
on the G60 figures, and all the late supplementation did was confirm his assumption.
Travelers had an opportunity to cross-examine Lorenzo on all the relevant numbers,
10

and to obtain its own rebuttal testimony. Travelers has not identified any way that
admission of Lorenzo’s confirmation of his prior assumption prejudices it, beyond the
fact that it lends support to Plaintiff’s response in opposition to the pending motion
to exclude Lorenzo’s testimony.
Although there is no reason Plaintiff could not have timely supplemented
Lorenzo’s testimony with confirmation that the roofing panels were “G60” panels,
there is little to no prejudice to Travelers if the Court admits the testimony. The Court
denies this aspect of Travelers’ motion.
E.

Conclusion
For these reasons, the Court grants in part and denies in part Travelers’

Motion to Strike [124] the affidavit of Dr. Fernando Lorenzo. The Court declines to
strike the entire affidavit. With respect to the specific sections addressed in Travelers’
briefing, the Court grants the motion as to Lorenzo’s citation of additional sources in
support of his opinions regarding the side panels’ loss of useful life, his new opinion
that the metal buildings lost 65% of their remaining useful life, and his new opinions
regarding the difficulty and desirability of repairing the metal roofs. But the Court
denies the motion as to Lorenzo’s supplementation of his prior assumption that the
roofing panels were “G60” panels.
III. MOTION TO EXCLUDE EXPERT TESTIMONY [105]
Travelers argues that three of the opinions provided by Plaintiff’s expert,
Fernando Lorenzo, should be excluded. Rule 702 provides:
11

A witness who is qualified as an expert by knowledge, skill, experience,
training, or education may testify in the form of an opinion or otherwise
if:
(a) the expert’s scientific, technical, or other specialized
knowledge will help the trier of fact to understand the evidence
or to determine a fact in issue;
(b) the testimony is based on sufficient facts or data;
(c) the testimony is the product of reliable principles and
methods; and
(d) the expert has reliably applied the principles and methods to
the facts of the case.
FED. R. EVID. 702. Therefore, “when expert testimony is offered, the trial judge must
perform a screening function to ensure that the expert’s opinion is reliable and
relevant to the facts at issue in the case.” Watkins v. Telsmith, Inc., 121 F.3d 984,
988-89 (5th Cir. 1997).
In Daubert v. Merrell Dow Pharms., Inc., 509 U.S. 579, 113 S. Ct. 2786, 125 L.
Ed. 2d 469 (1993), the Supreme Court provided a nonexclusive list of “general
observations intended to guide a district court’s evaluation of scientific evidence,”
including: “whether a theory or technique can be (and has been) tested, whether it
has been subjected to peer review and publication, the known or potential rate of
error, and the existence and maintenance of standards controlling the technique’s
operation, as well as general acceptance.” Watkins, 121 F.3d at 989 (punctuation
omitted).
Not every guidepost in Daubert will necessarily apply . . . , but the
district court’s preliminary assessment of whether the reasoning or
12

methodology underlying the testimony is scientifically valid and of
whether that reasoning or methodology properly can be applied to the
facts in issue is no less important.
Id. at 990-91 (punctuation omitted).
Expert testimony must be supported by “more than subjective belief or
unsupported speculation.” Paz v. Brush Eng’red Materials, Inc., 555 F.3d 383, 388
(5th Cir. 2009). It “must be reliable at each and every step or it is inadmissible. The
reliability analysis applies to all aspects of an expert’s testimony: the methodology,
the facts underlying the expert’s opinion, the link between the facts and the
conclusion, et alia.” Seaman v. Seacor Marine LLC, 326 F. App’x 721, 725 (5th Cir.
2009). “Overall, the trial court must strive to ensure that the expert, whether basing
testimony on professional studies or personal experience, employs in the courtroom
the same level of intellectual rigor that characterizes the practice of an expert in the
relevant field.” United States v. Valencia, 600 F.3d 389, 424 (5th Cir. 2010).
But the Court’s role as gatekeeper is not meant to supplant the adversary
system because “[v]igorous cross-examination, presentation of contrary evidence, and
careful instruction on the burden of proof are the traditional and appropriate means
of attacking shaky but admissible evidence.” Daubert, 509 U.S. at 596. The Court
should focus solely on the proposed expert’s “principles and methodology, not on the
conclusions that they generate.” Id. at 595. But “nothing in either Daubert or the
Federal Rules of Evidence requires a district court to admit opinion evidence
connected to existing data only by the ipse dixit of the expert.” GE v. Joiner, 522 U.S.
13

136, 146, 118 S. Ct. 512, 139 L. Ed. 2d 508 (1997).
In summary, the proponent of expert testimony must demonstrate that the
proposed expert is qualified, that the testimony is reliable, and that it is relevant to
a question of fact before the jury. United States v. Hicks, 389 F.3d 514, 525 (5th Cir.
2004). The proponent must prove these requirements “by a preponderance of the
evidence.” United States v. Fullwood, 342 F.3d 409, 412 (5th Cir. 2003).
A.

“Smoke”
Travelers argues that the Court should exclude Lorenzo’s description of the

HCl vapor as “smoke.” In his expert report, Lorenzo stated that Plaintiff’s property
was damaged by “Hydrochloric Acid (HCl) vapor or smoke that emanated from the
premises occupied by Baker Petrolite LLC.” Exhibit CC [108-29], at 4. During his
deposition, Lorenzo stated that he and his partner, Roger Craddock, decided to use
the term “smoke” in the report. Exhibit BB [108-28], at 20. He explained: “[I]f you
review, you know, the definitions, . . . they are so close together that we wanted to
make sure that what some people could refer to as a vapor, you know, it could also be
viewed as a smoke. And it’s basically either liquid or solid particles in air that will
reach a condition where light could not fully penetrate the . . . environment.” Id. When
asked whether there was any difference between “smoke” and “vapor,” Lorenzo said
that “they are . . . very much synonymous.” Id. at 21. When pressed to provide an
opinion as to whether what occurred in this case was “smoke” or “vapor,” Lorenzo
testified: “It’s both. Or it could be both because . . . when you have an acid vapor
14

release, you will have hydrochloric acid gas release to the . . . environment in
sufficient quantities that will not allow the light to penetrate.” Id.
First, Travelers contends that Lorenzo is not qualified to describe the liquid
vapor as “smoke.” Rule 702 provides that an expert may be qualified by “knowledge,
skill, experience, training, or education . . . .” FED. R. EVID. 702. Expert testimony
“serves to inform the jury about affairs not within the understanding of the average
man.” United States v. Moore, 997 F.2d 55, 57 (5th Cir. 1993). Therefore, “[a] district
court should refuse to allow an expert witness to testify if it finds that the witness is
not qualified to testify in a particular field or on a given subject.” Wilson v. Woods,
163 F.3d 935, 937 (5th Cir. 1999).
A proposed expert does not have to be “highly qualified in order to testify about
a given issue. Differences in expertise bear chiefly on the weight to be assigned to the
testimony by the trier of fact, not its admissibility.” Huss v. Gayden, 571 F.3d 442,
452 (5th Cir. 2009). Likewise, lack of personal experience “should not ordinarily
disqualify an expert, so long as the expert is qualified based on some other factor
provided by Rule 702 . . . .” United States v. Wen Chyu Liu, 716 F.3d 159, 168 (5th
Cir. 2013). Moreover, an “expert witness is not strictly confined to his area of practice,
but may testify concerning related applications; a lack of specialization does not affect
the admissibility of the opinion, but only its weight.” Id. at 168-69. Regardless of its
source, “the witness’s . . . specialized knowledge,” must be “sufficiently related to the
issues and evidence before the trier of fact that the witness’s proposed testimony will
15

help the trier of fact.” Id. at 167.
Lorenzo is qualified to provide the testimony cited above concerning whether
the acid vapor at issue in this case constituted “smoke,” as he defined the term. 1
Lorenzo has a Ph.D. in “Materials Science and Engineering.” Exhibit CC [108-29], at
16. He has over 35 years of experience in mechanical engineering. Id. This education
and experience is enough to qualify him to describe the vapor cloud as “smoke,” as he
defined the term. Any quibbles over his qualifications go to the weight of his
testimony, rather than its admissibility.
Travelers also argues that Lorenzo’s description of the HCl vapor as “smoke”
is unreliable because he performed no research as to what constitutes “smoke.” This
goes to the weight of his testimony, rather than its admissibility. First, this is not
necessarily the sort of testimony susceptible to testing or research, and every
guidepost in Daubert will not apply to every case. Watkins, 121 F.3d at 990. Lorenzo
provided a rational basis for his definition of the term “smoke,” however out of step it
might be with the ordinary and popular meaning of the term. Based on the current
record, the Court can not say that Lorenzo’s use of the term “smoke” is unreliable.
For these reasons, the Court denies this aspect of Travelers’ motion.

Under Mississippi law, “[t]he interpretation of insurance policy language is a question of law.”
Lewis v. Allstate Ins. Co., 730 So. 2d 65, 68 (Miss. 1998). Moreover, undefined terms in an insurance
policy are interpreted in their “plain, ordinary, and popular sense.” Blackledge v. Omega Ins. Co., 740
So. 2d 295, 298 (Miss. 1999). Therefore, while Lorenzo’s definition of “smoke” and his opinion as to
whether the HCl vapor constituted “smoke” may be reliable, they may also be irrelevant to any issue
before the jury. Accordingly, the Court’s rejection of Travelers’ arguments here do not necessarily
mean that all Lorenzo’s “smoke” opinions will be admissible at trial.

B.

Roofs’ Loss of Life
Next, Travelers argues that the Court should exclude Lorenzo’s opinion

regarding the loss of useful life to the roofs on Plaintiff’s metal buildings. The roofing
panels were made of galvanized steel, which is steel coated with zinc. Based on his
knowledge of industry standards, Lorenzo initially assumed that the roofing panels
had a zinc coating consistent with “G60” panels. Exhibit BB [108-28], at 28; Exhibit
4 [116-4], at 4. He then applied an equation based on the chemical reaction between
HCl and zinc to determine how much of the zinc would have been consumed by HCl.
Exhibit 4 [116-4], at 3-4. He used a pH level consistent with some of the third-party
samples taken from the scene. Id. Lorenzo later confirmed that the panels were “G60”
panels, but he learned (from Baker’s expert) that the zinc coating on “G60” panels
was thinner than he had originally believed. Id. at 4. He revised his calculations
accordingly. Id.; Exhibit BB [108-28], at 28. This was the reasoning underlying his
testimony that HCl vapors eroded the zinc coating on the roofing panels, reducing
their useful life.
Travelers argues that Lorenzo’s opinions are not supported by sufficient data,
and it challenges the connection between the data and his conclusions. Lorenzo relied
on samples taken by Richard Edwards, an engineer hired by Travelers. Edwards took
twelve usable samples from the Plaintiff’s property, and only six of the samples were
from roofs. Exhibit C to Motion in Limine #5 at 22, Burroughs Diesel, Inc. v. Travelers
Ind. Co. of Am., No. 2:18-CV-48-KS-MTP (S.D. Miss. Oct. 8, 2019), ECF No. 146-3.
17

Beyond cursory descriptions in the chart Edwards provided, Lorenzo did not know
where the samples were taken. Exhibit BB [108-28], at 40-42. Also, Edwards only
confirmed or denied the presence of chlorides, an indicator of HCl exposure, and
Lorenzo did not know the concentration of chlorides in any sample. Exhibit C [1463], at 22; Exhibit BB [108-28], at 61-62.
Lorenzo also assumed that every metal roof on Plaintiff’s property was exposed
to the same concentration of HCl, based on a limited number of data points. He
acknowledged this inferential leap in his report, noting that Edwards’ data “clearly
confirms that . . . almost every surface . . . was exposed to the highly corrosive effect
of the Hydrochloric Acid vapors released from Baker Petrolite.” Exhibit CC [108-29],
at 7. He took the inference a step further when calculating the roofs’ loss of zinc
coating. Lorenzo assumed that the roofs were exposed to HCl solution with a pH value
of 1.0, id. at 7, but Edwards only recorded a single sample with a pH value of 1.0 –
from the surface of an ice machine, rather than from a roof. Exhibit C [146-3], at 22.
Finally, Lorenzo’s opinion regarding the roofs’ loss of useful life is complete
speculation. Lorenzo assumed that the reduction in the useful life of the metal roofing
panels was equal to his calculated reduction in the zinc coating on the panels, without
articulating any methodology or reasoning to support such an inference. Exhibit CC

In response to these issues with Lorenzo’s testimony, Plaintiff notes that
Lorenzo’s opinions regarding the roofs’ loss of useful life are supported by calculations
18

based on samples taken from the site, known chemical reactions between zinc and
HCl, and the undisputed thickness of the zinc coating on the steel roofing panels.
Plaintiff contends that Travelers’ disputes with Lorenzo’s testimony are just “fodder
for cross-examination,” rather than grounds for exclusion.
Rule 702 specifically requires that an expert’s testimony be based upon
sufficient facts or data. FED. R. EVID. 702(b). Phrased differently, proposed expert
testimony “must be supported by appropriate validation – i.e. good grounds, based on
what is known.” Daubert, 509 U.S. at 509 (punctuation omitted). “Where an expert’s
opinion is based on insufficient information, the analysis is unreliable.” Paz, 555 F.3d
at 388; see also Seaman, 326 F. App’x at 725. Therefore, expert testimony must be
supported by “more than subjective belief or unsupported speculation.” Paz, 555 F.3d
at 300. “Although the Daubert reliability analysis is flexible and the proponent of
expert testimony need not satisfy every one of its factors, the existence of sufficient
facts is . . . in all cases mandatory,” Moore v. Int’l Paint, LLC, 547 F. App’x 513, 515
(5th Cir. 2013), and “a district court has broad discretion to determine whether a body
of evidence relied upon by an expert is sufficient to support that expert’s opinion.”
Knight v. Kirby Inland Marine Inc., 482 F.3d 347, 354 (5th Cir. 2007). “Overall, the
trial court must strive to ensure that the expert, whether basing testimony on
professional studies or personal experience, employs in the courtroom the same level
of intellectual rigor that characterizes the practice of an expert in the relevant field.”
Valencia, 600 F.3d at 424.
19

Moreover, while “reliable expert testimony often involves estimation and
reasonable inferences from a sometimes incomplete record,” an expert may not make
“numerous assumptions with no apparent underlying rationale.” Moore, 547 F. App’x
at 516. Experts can build up to conclusions through basic scientific premises, but “the
extrapolation or leap . . . must be reasonable and scientifically valid.” Moore v.
Ashland Chem. Inc., 151 F.3d 269, 279 (5th Cir. 1998). “[C]ourts are free to reject a
theory based on extrapolation when ‘there is simply too great an analytical gap
between the data and the opinion proffered.’” Johnson v. Arkema, Inc., 685 F.3d 452,
460-61 (5th Cir. 2012) (quoting Joiner, 522 U.S. at 146). As noted above, “nothing in
either Daubert or the Federal Rules of Evidence requires a district court to admit
opinion evidence connected to existing data only by the ipse dixit of the expert.”
Joiner, 522 U.S. at 146.
Here, Plaintiff has not offered any substantial opposition to Travelers’
argument. Plaintiff doesn’t dispute that Lorenzo based his opinions regarding the
metal roofs on a limited number of samples from a variety of surfaces throughout
Plaintiff’s property. Likewise, Plaintiff does not dispute that Lorenzo doesn’t know
where the samples were taken or the concentration of chlorides in each sample.
Even if the Court agreed with Plaintiff that the problems with the data go to
the weight of Lorenzo’s testimony, rather than its admissibility, his conclusions still
rest on various unsupported inferences and extrapolations. He assumed that the HCl
exposure level of every metal roof was at least the same as that of an ice machine. He
20

reasoned that the roofs would have actually received more exposure to HCl than the
ice machine because they were not under cover, and that the ice machine sample had
a lower pH than the roof samples because the roofs had been exposed to rain during
the two weeks between the spill and Edwards’ inspection. Lorenzo also assumed that
the reduction in the useful life of the metal roofing panels was equal to his calculated
reduction in the zinc coating on the panels, without articulating any methodology or
reasoning to support such an inference.
The Court finds that Lorenzo’s opinions regarding the remaining useful life of
the roofing panels on Plaintiffs’ metal buildings is unreliable because of the
combination of 1) their sketchy factual basis, and 2) Lorenzo’s unsupported inferences
and extrapolations from the already limited facts. The Court grants Travelers’ motion
as to this issue.
C.

Side Panels’ Loss of Life
Finally, Travelers argues that the Court should exclude Lorenzo’s opinions

regarding the loss of useful life to the metal buildings’ side panels. Travelers argues
that Lorenzo based his opinion on insufficient data, that he relied on a single
unreliable source, and that his conclusions are based on blind conjecture.
As noted above, Lorenzo relied on samples taken by Richard Edwards, a
consultant hired by Travelers. Edwards only took twelve usable samples from
Plaintiff’s property, and Lorenzo doesn’t know whether any of them are from the side
panels of Plaintiff’s metal buildings. Exhibit C [146-3], at 22; Exhibit BB [108-28], at
21

41-43. Regardless, Edwards only confirmed or denied the presence of chlorides, an
indicator of HCl exposure, and Lorenzo doesn’t know the concentration of chlorides
at any specific location on the property. Exhibit C [146-3], at 22; Exhibit BB [108-28],
at 62.
Also, during his deposition, Lorenzo admitted that the only basis for his
opinion that the painted metal side panels had lost 50% of their useful life was an
article from www.hunker.com, a do-it-yourself home repair website. Exhibit BB [10828], at 48-49. The record contains no evidence that this is the sort of authority
typically relied on by experts in the fields of metallurgy and/or mechanical
engineering. See Valencia, 600 F.3d at 424.
Finally, Lorenzo provided no basis whatsoever for his assumption that the side
panels had lost 50% of their useful life. With respect to the roofs, he performed
calculations based on the chemical reaction between HCl and zinc. He performed no
such calculation with respect to the paint on the side panels, and expressed no opinion
as to the amount of paint eroded by HCl. He noted that some paints include metal
compounds, and, therefore, he assumed that the HCl would react with the paint in
the same way it theoretically reacted with the zinc on the roofing panels. Exhibit BB
[108-28], at 67. But he did not identify any metal compounds in the paint on the side
panels or perform calculations as he did with the roofing panels. He assumed that
there were metals in the paint and pulled a number out of thin air as to the amount
of paint eroded by HCl. See id. at 49, 67. Then he assumed – without articulating any
22

supporting methodology or rationale – that a loss of 50% of the paint would cause a
50% loss in the useful life of the side panels.
The Court excludes Lorenzo’s opinion regarding the loss of useful life of the
metal buildings’ side panels because 1) he failed to demonstrate that the single source
he relied on in support of his opinion was the sort typically relied on by experts in his
field, and 2) his failure to articulate a methodology or rationale in support of opinions
regarding the amount of paint eroded and loss of useful life. The Court grants
Travelers’ motion as to this issue.
IV. CONCLUSION
For these reasons, the Court grants in part and denies in part Travelers’
Motion to Strike [124] an affidavit from Plaintiff’s expert, Dr. Fernando Lorenzo.
Specifically, the Court declines to strike the entire affidavit. With respect to the
sections addressed in Travelers’ briefing, the Court grants the motion as to Lorenzo’s
citation of additional sources in support of his opinions regarding the side panels’ loss
of useful life, his new opinion that the metal buildings lost 65% of their remaining
useful life, and his new opinions regarding the difficulty and desirability of repairing
the metal roofs. But the Court denies the motion as to Lorenzo’s supplementation of
his prior assumption that the roofing panels were “G60” panels.
The Court also grants in part and denies in part Travelers’ Motion to
Exclude [105] the testimony of Plaintiff’s expert, Dr. Fernando Lorenzo. The Court
denies the motion as to Lorenzo’s use of the term “smoke,” but the Court grants the
23

motion as to Lorenzo’s opinions regarding the remaining useful life of the roofing and
side panels on Plaintiffs’ metal buildings.
SO ORDERED AND ADJUDGED this 25th day of October, 2019.
