Milsap v. BP Exploration & Production, Inc. et al Doc. 67 Case 2:17-cv-04451-LMA-MBN Document 67 Filed 08/15/22 Page 1 of 20 UNITED STATES DISTRICT COURT EASTERN DISTRICT OF LOUISIANA DENNIS MILSAP CIVIL ACTION VERSUS No. 17-4451 BP EXPLORATION & PRODUCTION INC., ET AL. SECTION I ORDER & REASONS Before the Court is a motion 1 in limine to exclude the opinions of plaintiff ’s medical causation expert, Dr. Jerald Cook (“Cook”), filed by defendants, BP Exploration & Production, Inc.; BP America Production Company; BP p.l.c.; Halliburton Energy Services, Inc.; Transocean Deepwater, Inc; Transocean Holdings, LLC; and Transocean Offshore Deepwater Drilling, Inc. (collectively, “defendants”). Defendants have also filed a motion 2 for summary judgment, contending that if the Court grants defendants’ motion in limine, then summary judgment will also be warranted because plaintiff, Dennis Milsap (“Milsap”), will lack necessary expert testimony. Milsap opposes 3 both motions, and has filed a motion4 to continue all scheduling deadlines until his counsel has completed discovery on the issue of causation and to continue indefinitely the submission date for defendants’ motion for summary judgment and motion in limine. The defendants oppose Milsap’s motion to 1 R. Doc. No. 46 (motion); R. Doc. No. 62 (reply). R. Doc. No. 47 (motion); R. Doc. No. 61 (reply). 3 R. Doc. No. 49 (opposition to motion for summary judgment); R. Doc. No. 50 (opposition to motion in limine). 4 R. Doc. No. 64. 2 Dockets.Justia.com Case 2:17-cv-04451-LMA-MBN Document 67 Filed 08/15/22 Page 2 of 20 continue. 5 For the following reasons, the Court grants the defendants’ motion in limine and motion for summary judgment and the Court denies Milsap’s motion to continue. I. BACKGROUND The instant action is a “B3” case arising out of the 2010 Deepwater Horizon oil spill in the Gulf of Mexico. 6 B3 cases involve “claims for personal injury and wrongful death due to exposure to oil and/or other chemicals used during the oil spill response (e.g., dispersant).” In re Oil Spill by Oil Rig “Deepwater Horizon” in Gulf of Mexico, on Apr. 20, 2010, No. MDL 2179, 2021 WL 6053613, at *9 (E.D. La. Apr. 1, 2021) (Barbier, J.). In the course of the MDL proceedings, Judge Barbier approved the Deepwater Horizon Medical Benefits Class Action Settlement Agreement, which included a Back-End Litigation Option (“BELO”) permitting certain class members to sue the defendants for later-manifested physical conditions. Id. at *2. The B3 plaintiffs, by contrast, either opted out of the class action settlement agreement or were excluded from its class definition. Id. at *10 n.3. To prevail on their claims, the “B3 plaintiffs must prove that the legal cause of the claimed injury or illness is exposure to oil or other chemicals used during the response.” 7 Milsap was employed in the Deepwater Horizon (“DWH”) oil spill response. According to his filings, he worked as a member of the onshore clean-up crew. 8 He 5 R. Doc. No. 65. R. Doc. No. 6 (“Severing 780 Cases in the B3 Pleading Bundle and Re-allotting Them Among the District Judges of the Eastern District of Louisiana”) (Barbier, J.). 7 Id. at 53 (noting that “proving causation will be a key hurdle for the B3 plaintiffs.”). 8 R. Doc. No. 46-1. 6 2 Case 2:17-cv-04451-LMA-MBN Document 67 Filed 08/15/22 Page 3 of 20 claims to have worked for “10-12 hours per day for 5-7 days per week” from May 2010 to December 2011 on the beaches and islands of Mississippi. 9 Plaintiff alleges that exposure to crude oil and chemical dispersants caused him to develop a multitude of adverse medical conditions, including pharyngitis, sore throat, bronchitis, nasal congestion, chronic sinusitis, difficulty swallowing, hoarseness, nosebleeds, chronic rhinitis, facial pain or sinus pain, nasal discharge, throat irritation, abdominal pain, loss of appetite, chronic heartburn, abdominal cramps, diarrhea, nausea, vomiting, weakness, thrombocytopenia, pleuritic chest pain, shortness of breath, blurred vision, eye irritation and burning, rash, skin crusting, dryness/flaking, itching, peeling, scaling, difficulty walking, headaches, dizziness, depression, and anxiety. 10 To support his claim that exposure to oil and dispersants caused his health problems, Milsap provides a medical causation analysis completed by Cook. 11 Cook is a retired Navy physician, a fellow of the American College of Occupational and Environmental Medicine, and is board certified in occupational medicine, public health, and general preventative medicine. 12 Cook’s report utilized a “general causation approach to determine if a reported health complaint can be the result of exposures sustained in performing cleanup work” and to assess “the likelihood that occupational exposures that occurred during work in oil spill cleanup caused disease, contributed to the development of disease, 9 Id. at 5.

The first chapter outlines Cook’s qualifications, which are not challenged. 14 The second chapter provides background on the Deepwater Horizon oil spill. The third chapter describes Cook’s methodology. The first step, as described in Cook’s report, is to “review and analyze the available scientific literature to determine the strength of an association between environmental exposure and a health effect.” 15 Cook states that, as part of this literature review, he selected the studies included in his general causation analysis “based on the quality of the study and study design.” 16 Finally, Cook applies the Bradford Hill factors to the selected studies to “to determine if a cause-and-effect relationship exists or not.” 17 The Bradford Hill factors, which environmental toxicologists employ for causation analysis, include: (1) temporal relationship; (2) strength of the association; (3) dose-response relationship; (4) replication of findings; (5) biological plausibility; (6) consideration of alternative explanations; (7) cessation of exposure; (8) specificity of the association; and (9) consistency with other knowledge. Grant v. BP Expl. & Prod., Inc., No. 17-4334, 2022 13 Id. at 14. R. Doc. No. 43-1, at 3. 15 R. Doc. No. 47-6, at 17. 16 Id. at 19. 17 Id. at 24. “Sir Bradford Hill was a world-renowned epidemiologist who articulated a nine-factor set of guidelines in his seminal methodological article on causality inferences.” Jones v. Novartis Pharm. Corp., 234 F. Supp. 3d 1244, 1267 (N.D. Ala. 2017) (internal citations and quotations omitted). 14 4 Case 2:17-cv-04451-LMA-MBN Document 67 Filed 08/15/22 Page 5 of 20 WL 2467682, at *4 (E.D. La. July 6, 2022) (Vance, J.) (citing Fed. Judicial Ctr., Reference Manual on Scientific Evidence 600 (3d ed. 2011)). Cook explains that “[d]rawing causal inferences after finding an association and considering these factors requires judgment and analysis to determine if a cause-and-effect relationship exists or not.” 18 The fourth chapter of Cook’s report recounts the history of oil spills and related clean-up efforts and analyzes prior studies on the health effects associated with exposure to oil. 19 These studies include the National Institute for Occupational Safety and Health’s (“NIOSH”) 2011 final health hazard evaluation (“HHE”) report on the Deepwater Horizon oil spill, the Deepwater Horizon oil spill Coast Guard cohort study, and the Gulf Long-Term Follow-Up study (“GuLF Study”). Cook, following a close analysis of the above studies, concludes that there is a relationship between oil exposure among clean-up workers and a number of dermal, ocular, neurological, and respiratory conditions. 20 18 R. Doc. No. 47-6, at 24. Id. at 32. 20 “During the response and cleanup activities, workers complained of various acute medical symptoms, including nasal congestion, cough, shortness of breath, headaches, nausea, dizziness, dermal irritation or rash, itchy and sore eyes, as well as heat-related conditions.” Id. at 36 (discussing the results of the NIOSH HHE report); “Neurological symptoms were also noted to have a significant relationship in oil-exposed responders, including headaches, lightheadedness, difficulty concentrating, numbness/tingling sensation, blurred vision, and memory loss or confusion . . . . The cohort was also determined to have demonstrated a significant association between oil-exposed responders and hypertension, as well as chest pain, mitral valve disorders, sudden heartbeat changes, and palpitations . . . .” Id. at 44 (describing the “longitudinal data that shows a significant relationship between oilexposed responders and respiratory symptoms” from the ongoing Coast Guard cohort study); Symptoms, such as coughing, wheezing, burning in nose, throat, lungs, and 19 5 Case 2:17-cv-04451-LMA-MBN Document 67 Filed 08/15/22 Page 6 of 20 Finally, the fifth chapter contains Cook’s opinions on general causation for four categories of medical conditions: (1) respiratory conditions; (2) dermal conditions; (3) ocular conditions; and (4) cancers. Ultimately, Cook concludes that a “[g]eneral causation analysis indicates that these acute and chronic [respiratory, dermal, ocular] conditions can occur in individuals exposed to crude oil, including weathered crude oil, during oil spill response and cleanup work.” 21 II. STANDARDS OF LAW A. Motion in Limine Federal Rule of Evidence 702 governs the admissibility of expert witness testimony. Daubert v. Merrell Dow Pharmaceuticals, 509 U.S. 579, 588 (1993); United States v. Hitt, 473 F.3d 146, 148 (5th Cir. 2006). Rule 702 provides: 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. eyes “had a positive association with both direct work with dispersants and indirect work with dispersants . . . .” Id. at 59 (discussing the results of the GuLF Study). 21 Id. at 87, 92, 99. With respect to cancers, Cook notes that “[m]ost of the studies that have been done . . . show increased prevalence in acute symptoms . . . .” However, he also notes that, because of the differing latency periods for various cancers, “[a]t this time there are no epidemiology studies that show exposures to crude oil, weathered crude oil, or dispersants cause cancer.” Id. at 99–102. 6 Case 2:17-cv-04451-LMA-MBN Document 67 Filed 08/15/22 Page 7 of 20 “To qualify as an expert, ‘the witness must have such knowledge or experience in [his] field or calling as to make it appear that his opinion or inference will probably aid the trier in his search for truth.’” United States v. Hicks, 389 F.3d 514, 524 (5th Cir. 2004) (quoting United States v. Bourgeois, 950 F.2d 980, 987 (5th Cir. 1992)). Daubert “provides the analytical framework for determining whether expert testimony is admissible under Rule 702.” Pipitone v. Biomatrix, Inc., 288 F.3d 239, 243 (5th Cir. 2002). Both scientific and nonscientific expert testimony is subject to the Daubert framework, which requires a trial court to make a preliminary assessment to “determine whether the expert testimony is both reliable and relevant.” Burleson v. Tex. Dep’t of Criminal Justice, 393 F.3d 577, 584 (5th Cir. 2004); see Kumho Tire, 526 U.S. at 147. A number of nonexclusive factors may be considered with respect to the reliability inquiry, including: (1) whether the technique has been tested, (2) whether the technique has been subjected to peer review and publication, (3) the technique’s potential error rate, (4) the existence and maintenance of standards controlling the technique’s operation, and (5) whether the technique is generally accepted in the relevant scientific community. Burleson, 393 F.3d at 584. The reliability inquiry must remain flexible, however, as “not every Daubert factor will be applicable in every situation; and a court has discretion to consider other factors it deems relevant.” Guy v. Crown Equip. Corp., 394 F.3d 320, 325 (5th Cir. 2004); see Runnels v. Tex. Children’s Hosp. Select Plan, 167 F. App’x 377, 381 (5th Cir. 2006) (“[A] trial judge has ‘considerable leeway’ in determining ‘how to test an expert’s reliability.’” (quoting 7 Case 2:17-cv-04451-LMA-MBN Document 67 Filed 08/15/22 Page 8 of 20 Kumho Tire, 526 U.S. at 152)). “Both the determination of reliability itself and the factors taken into account are left to the discretion of the district court consistent with its gatekeeping function under [Rule] 702.” Munoz v. Orr, 200 F.3d 291, 301 (5th Cir. 2000). As for determining relevancy, the proposed testimony must be relevant “not simply in the way all testimony must be relevant [under Rules 401 and 402], but also in the sense that the expert’s proposed opinion would assist the trier of fact to understand or determine a fact in issue.” Bocanegra v. Vicmar Servs., Inc., 320 F.3d 581, 584 (5th Cir. 2003). “There is no more certain test for determining when experts may be used than the common sense inquiry whether the untrained layman would be qualified to determine intelligently and to the best degree the particular issue without enlightenment from those having a specialized understanding of the subject involved in the dispute.” Vogler v. Blackmore, 352 F.3d 150, 156 n.5 (5th Cir. 2003) (quoting Fed. R. Evid. 702, Advisory Committee Note). “[W]hen expert testimony is challenged under Rule 702 and Daubert, the burden of proof rests with the party seeking to present the testimony.” Kennedy v. Magnolia Marine Transp. Co., 189 F. Supp. 3d 610, 615 (E.D. La. 2016) (Africk, J.). The Court applies a preponderance of the evidence standard when performing its gatekeeping function under Daubert. See Daubert, 509 U.S. at 592 n.10. And the Court is not bound by the rules of evidence—except those rules concerning privileges—when doing so. See id. 8 Case 2:17-cv-04451-LMA-MBN Document 67 Filed 08/15/22 Page 9 of 20 B. Summary Judgment Summary judgment is proper when, after reviewing the pleadings, the discovery and disclosure materials on file, and any affidavits, a court determines that there is no genuine dispute of material fact and the movant is entitled to judgment as a matter of law. Fed. R. Civ. P. 56(a). “[A] party seeking summary judgment always bears the initial responsibility of informing the district court of the basis for its motion, and identifying those portions of [the record] which it believes demonstrate the absence of a genuine issue of material fact.” Celotex Corp. v. Catrett, 477 U.S. 317, 323 (1986). The party seeking summary judgment need not produce evidence negating the existence of a material fact; it need only point out the absence of evidence supporting the other party’s case. Id.; see also Fontenot v. Upjohn Co., 780 F.2d 1190, 1195–96 (5th Cir. 1986) (“There is no sound reason why conclusory allegations should suffice to require a trial when there is no evidence to support them even if the movant lacks contrary evidence.”). Once the party seeking summary judgment carries that burden, the nonmoving party must come forward with specific facts showing that there is a genuine dispute of material fact for trial. See Matsushita Elec. Indus. v. Zenith Radio Corp., 475 U.S. 574, 587 (1986). The showing of a genuine issue is not satisfied by creating “‘some metaphysical doubt as to the material facts,’ by ‘conclusory allegations,’ by ‘unsubstantiated assertions,’ or by only a ‘scintilla’ of evidence.” Little v. Liquid Air Corp., 37 F.3d 1069, 1075 (5th Cir. 1994) (citations omitted). Rather, a genuine issue of material fact exists when the “evidence is such that a reasonable 9 Case 2:17-cv-04451-LMA-MBN Document 67 Filed 08/15/22 Page 10 of 20 jury could return a verdict for the nonmoving party.” Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 248 (1986). “Although the substance or content of the evidence submitted to support or dispute a fact on summary judgment must be admissible . . . the material may be presented in a form that would not, in itself, be admissible at trial.” Lee v. Offshore Logistical & Transp., L.L.C., 859 F.3d 353, 355 (5th Cir. 2017) (citations omitted). The party responding to the motion for summary judgment may not rest upon the pleadings but must identify specific facts that establish a genuine issue. See Anderson, 477 U.S. at 248. The nonmoving party’s evidence, however, “is to be believed, and all justifiable inferences are to be drawn in [the nonmoving party’s] favor.” Id. at 255. If the movant demonstrates the absence of a genuine issue of material fact, the nonmovant must then articulate specific facts showing a genuine issue and point to supporting, competent evidence that may be presented in a form admissible at trial. See Lynch Props., Inc. v. Potomac Ins. Co., 140 F.3d 622, 625 (5th Cir. 1998); Fed. R. Civ. P. 56(c)(1)(A), (c)(2). These facts must create more than “some metaphysical doubt as to the material facts.” Matsushita, 475 U.S. at 586. If the nonmovant fails to meet their burden of showing a genuine issue for trial that could support a judgment in favor of the nonmovant, summary judgment must be granted. See Little, 37 F.3d at 1075–76. 10 Case 2:17-cv-04451-LMA-MBN Document 67 Filed 08/15/22 Page 11 of 20 III. A. LAW & ANALYSIS Defendants’ Motion in Limine B3 plaintiffs have the burden of proving that “the legal cause of the claimed injury or illness is exposure to oil or other chemicals used during the response.” In re Oil Spill by Oil Rig “Deepwater Horizon”, 2021 WL 6053613, at *11; accord Perkins v. BP Expl. & Prod., Inc., No. 17-4476, 2022 WL 972276, at *2 (E.D. La. Mar. 31, 2022) (Milazzo, J.). When determining the admissibility of causation evidence in toxic tort cases, “[c]ourts use ‘a two-step process . . . . First, the district court must determine whether there is general causation. Second, if it concludes that there is admissible generalcausation evidence, the district court must determine whether there is admissible specific-causation evidence.’” Seaman v. Seacor Marine, LLC, 326 F. App’x 721, 722 (5th Cir. 2009) (quoting Knight v. Kirby Inland Marine, Inc., 482 F.3d 347, 351 (5th Cir. 2007) (emphases added in Seaman)). “General causation is whether a substance is capable of causing a particular injury or condition in the general population, while specific causation is whether a substance caused a particular individual’s injury.” Id. (quoting Knight, 482 F.3d at 351). With respect to general causation, “[s]cientific knowledge of the harmful level of exposure to a chemical, plus knowledge that the plaintiff was exposed to such quantities, are minimal facts necessary to sustain the plaintiffs’ burden in a toxic tort case.” Seaman, 326 F. App’x at 723 (quoting Allen v. Penn. Eng’g Corp., 102 F.3d 194, 199 (5th Cir. 1996)). “A plaintiff in such a case cannot expect lay fact-finders to 11 Case 2:17-cv-04451-LMA-MBN Document 67 Filed 08/15/22 Page 12 of 20 understand medical causation; expert testimony is thus required to establish causation.” Id. Defendants assert that Cook’s general causation opinion should be excluded because it is unreliable to the extent that the opinion fails: (1) to identify a harmful dose of exposure to any particular chemical 22; (2) to verify Milsap’s diagnosis23; and (3) to follow accepted methodology for evaluating scientific literature. 24 This Court will begin by addressing the defendants’ first argument for finding Cook’s opinion to be unreliable—namely, that the opinion does not identify a harmful level of exposure to an identified chemical and therefore cannot prove general causation. The Court agrees with this argument. The Cook report in the present case suffers from the same flaws which the Court identified in an earlier version of Cook’s report excluded in Murphy v. BP Expl. & Prod. Inc., No. 13-1031, 2022 WL 1460093 (E.D. La. May 9, 2022), and Novelozo v. BP Expl. & Prod. Inc., No. 13-1033, 2022 WL 1460103 (E.D. La. May 9, 2022), insofar as Cook fails to identify a particular chemical and corresponding dose to which Milsap was exposed. As this Court noted in Novelozo, “[s]cientific knowledge of the harmful level of exposure to a chemical, plus knowledge that the plaintiff was exposed to such quantities, are minimal facts necessary to sustain the plaintiffs’ burden [as to general causation] in a toxic tort case.” 2022 WL 1460103, at *5 (quoting Seaman v. Seacor Marine, LLC, 326 F. App’x 721, 722 (5th Cir. 2009)). Several sections of this Court 22 R. Doc. No. 46-1, at 7–11. Id. at 11–12. 24 Id. at 12–16. 23 12 Case 2:17-cv-04451-LMA-MBN Document 67 Filed 08/15/22 Page 13 of 20 have subsequently concluded that “Cook’s failure to identify the level of exposure to a relevant chemical that can cause the conditions asserted in plaintiff's complaint renders his opinion unreliable, unhelpful, and incapable of establishing general causation.” Grant v. BP Expl. & Prod. Inc., No. 17-4334, 2022 WL 2467682, at *7 (E.D. La. July 6, 2022) (Vance, J.); see also, Reed v. BP Expl. & Prod., Inc., No. 173603, 2022 WL 3099925, at *3 (E.D. La. Aug. 4, 2022) (Milazzo, J.); Favorite v. BP Expl. & Prod., Inc., No. 17-3192, 2022 WL 2789029, at *3 (E.D. La. July 15, 2022) (Zainey, J.); Barkley v. BP Expl. & Prod. Inc., No. 13-995, 2022 WL 2342474, at *4 (E.D. La. June 29, 2022) (Barbier, J); Harrison v. BP Expl. & Prod., No. 17-4346, 2022 WL 2390733, at *6 (E.D. La. July 1, 2022) (Morgan, J.); Street v. BP Expl. & Prod. Inc., No. 17-3619, 2022 WL 1811144, at *6 (E.D. La. June 2, 2022) (Ashe, J.). Milsap addresses this lack of dose-response data in Cook’s report by asserting that the defendants’ failure to conduct dermal and biomonitoring of clean-up workers—which Milsap submits “would have created a quantitative exposure and dose database for these workers” 25—is evidence that “BP consciously, or in the most favorable light negligently, avoided recording data which would show the exposure doses of spill workers.” 26 Yet, as noted by other courts, the Deepwater Horizon oil spill Unified Area Command, which was composed of several federal and state agencies, “engaged in extensive and coordinated data collection and environmental monitoring efforts, in what has been characterized as ‘the largest environmental investigation of 25 26 R. Doc. No. 50, at 4. Id. at 9. 13 Case 2:17-cv-04451-LMA-MBN Document 67 Filed 08/15/22 Page 14 of 20 an oil spill ever undertaken.’” In re Deepwater Horizon Belo Cases, 2020 WL 6689212, at *4 (N.D. Fla. Nov. 4, 2020), aff’d sub nom. In re Deepwater Horizon BELO Cases, 2022 WL 104243 (11th Cir. Jan. 11, 2022); accord Peairs v. BP Expl. & Prod., Inc., No. 17-3596, 2022 WL 2817852, at *10 n.53 (E.D. La. July 19, 2022) (Vance, J.). The availability of this data “cast[s] doubt on the assertion that there is a lack of monitoring data associated with the spill.” Peairs, 2022 WL 2817852, at *10 n.53; see also Harrison, 2022 WL 2390733, at *7. The defendants also argue that Cook’s failure to verify Milsap’s diagnosis 27 further renders his opinion unreliable. Per the American Medical Association’s Guide to the Evaluation of Disease and Injury Causation (“AMA Guide”): The first step is to establish or verify the diagnosis (i.e., determine what is wrong with the patient, or what does the patient have?). This step is accomplished by careful review of the available medical records and/or examination of the patient. […] Exposure becomes relevant only when the presence of disease or illness is established. 28 Expert testimony “must be reliable at each and every step or else it is inadmissible.” Knight, 482 F.3d at 355. The Court’s review of the relevant section of the AMA Guide—which defendants lodged in the record—demonstrates that the AMA’s framework is a published technique with explicit standards controlling its operation. Burleson, 393 F.3d at 584 (discussing the nonexclusive factors for the reliability inquiry). But Cook’s failure to perform step one of the AMA Guide’s is concerning because “[e]xposure becomes relevant only when the presence of disease or 27 Cook’s report does not mention Milsap—or any B3 plaintiff—specifically. Melhorn, M.D., et al., AMA Guide to the Evaluation of Disease and Injury Causation, (2d ed.) (attached to defendants’ motion as R. Doc. No. 46-6), at 578. 28 14 Case 2:17-cv-04451-LMA-MBN Document 67 Filed 08/15/22 Page 15 of 20 illness is established.” 29 Cook’s failure to establish Milsap’s potential diseases reveals that Cook has not “reliably applied the principles and methods to the facts of this case.” Fed. R. Evid. 702(d). This deficiency is particularly concerning because “the fundamental question underlying [Cook’s] testimony,” and the Court’s ruling on defendants’ Daubert motion is “whether the chemicals that [Milsap was] exposed to and the type of exposures [Milsap] experienced cause [Milsap’s illnesses].” Knight, 482 F.3d at 352. Without verifying Milsap’s diagnoses, Cook has not sufficiently explained how any particular study can provide “a reliable basis for the opinion that the types of chemicals [Milsap was] exposed to could cause [his] particular injury in the general population.” Id. at 353. As this Court has noted previously, “[w]hile this shortcoming is not dispositive in the Court’s analysis, it is a factor that weighs against admitting Cook’s opinions.” Finally, as the defendants argue in their motion in limine and as other sections of this Court have agreed, Cook’s reliance on the “ever vs. never” binary exposure model in his report raises concerns about the reliability of his methodology. See Grant, 2022 WL 2467682, at *10–11. Cook’s report states that “GuLF STUDY researchers . . . noted that it would be difficult to obtain accurate and comprehensive exposure information on participants” in the study as “many of the assessments would have been made months after the workers were exposed.” 30 Cook also notes that NIOSH investigators researching the Deepwater Horizon spill “disregarded the 29 30 Id. (emphasis added). R. Doc. No. 47-6, at 57. 15 Case 2:17-cv-04451-LMA-MBN Document 67 Filed 08/15/22 Page 16 of 20 self-reports of [some] workers, determining that the workers’ self-reported exposures had not been likely.” 31 Accordingly, as the data Cook relied upon for his “ever vs. never” exposure model itself is of suspect reliability, his analysis suffers from the same lack of reliability. Collectively, concerns for the reliability of Cook’s report based on his failure to identify a harmful level of exposure, to verify Milsap’s diagnoses, and to use acceptable methodology in evaluating the scientific literature referenced in his report render his opinion unreliable. B. Defendants’ Motion for Summary Judgment Having determined that Cook’s report should be excluded, the Court now turns to defendants’ motion for summary judgment. The issue of general causation is a necessary element of plaintiff’s claims against defendants. Cook is Milsap’s sole expert on general causation. 32 With Cook’s opinion on general causation now excluded, Milsap lacks expert testimony with respect to general causation. As a result, Milsap has failed to present a genuine issue of material fact with respect to his claims that his injuries were caused by exposure to oil and dispersants. 31 Id. at 42. Milsap’s opposition to the defendants’ motion in limine also notes that Dr. Rachel Jones “prepare[d] a general exposure assessment based on the available exposure data and upon the published exposure assessment literature, most of which deals specifically with exposure assessment of BP Oil Spill response workers.” Id. at 3. However, Dr. Jones’ report does not offer an opinion on general causation. Additionally, Dr. Jones is not a medical doctor and therefore is not qualified to opine on Milsap’s medical diagnoses. Accordingly, Dr. Jones’ report does not cure plaintiff’s deficiency as to general causation evidence. See, e.g., Peairs, 2022 WL 2817852, at *12. 32 16 Case 2:17-cv-04451-LMA-MBN Document 67 Filed 08/15/22 Page 17 of 20 Accordingly, defendants are entitled to summary judgment. See, e.g., Reed, 2022 WL 3099925, at *3; Favorite, 2022 WL 2789029, at *3; Grant, 2022 WL 2467682, at *12; Barkley, 2022 WL 2342474, at *6; Harrison, 2022 WL 2390733, at *7; Street, 2022 WL 1811144, at *7; Novelozo, 2022 WL 1460103, at *10. C. Milsap’s Motion to Continue Milsap seeks to continue all scheduling deadlines until his counsel has completed discovery on the issue of causation, and to continue indefinitely the submission date for defendants’ motion for summary judgment and motion in limine. 33 Milsap first argues that the Court should continue all scheduling deadlines to “allow factual discovery aimed at individual plaintiff issues to be put on hold while discovery proceeds on what has become the defining legal issue—general causation . . . .” 34 Next, Milsap asserts that the Court should continue the submission deadlines for the defendants’ motion for summary judgment and motion in limine to “allow time for the discovery disputes to be resolved, and discovery relating to BP and biomonitoring to be completed” 35 in Torres-Lugo v. BP Exploration & Production, Inc., No. 20-210 (E.D. La. June 3, 2022), a case pending before another section of this Court. At issue in Torres-Lugo is a motion for sanctions filed by another B3 plaintiff against the same defendants in the present case, alleging that David Dutton, BP’s 33 R. Doc. No. 64-1, at 1. Id. at 4. 35 Id. 34 17 Case 2:17-cv-04451-LMA-MBN Document 67 Filed 08/15/22 Page 18 of 20 30(b)(6) witness, “failed to properly respond to questions and seek information necessary to be a corporate representative witness” 36 as to the issue of BP’s dermal monitoring and biomonitoring of cleanup workers. However, the issue of BP’s alleged failure to collect biomonitoring data does not address the dispositive question at hand—whether Cook’s report is sufficient to establish general causation. Whether the Torres-Lugo court decides that sanctions are warranted and whether these potential sanctions would result in more discovery pertaining to BP’s collection of biomonitoring data is irrelevant. Sanctions and more discovery on BP’s internal decision-making regarding collecting data have no effect on the data actually available to Cook to prove general causation and therefore are not outcome determinative of BP’s motions currently before the Court. Moreover, as noted above, Cook’s general causation analysis was not limited to data from BP or derived from the Deepwater Horizon spill; Cook had other data available to him to support his analysis. For example, the Unified Area Command “engaged in extensive and coordinated data collection and environmental monitoring efforts . . . .” Belo Cases, 2020 WL 6689212, at *4. Cook could have sought to support his general causation analysis with data collected as part of these efforts, as well as by “relying on the universe of relevant epidemiology and toxicology literature studying the spill or by relying on the work of Dr. Jones.” Harrison, 2022 WL 2390733, at *7. Additionally, as noted by another section of the Court, Cook could also have buttressed his analysis with epidemiological studies of the health effects on 36 Id. at 6. 18 Case 2:17-cv-04451-LMA-MBN Document 67 Filed 08/15/22 Page 19 of 20 responders from prior oil spills, not just from data on the Deepwater Horizon spill. Grant v. BP Exploration & Production, Inc., No. 17-4334 (E.D. La. July 6, 2022) (ECF No. 63) (Vance, J.). The dispute at issue in the Torres-Lugo case has no effect on the data available to Cook, and therefore has no effect on the Court’s analysis regarding the defendant’s pending motions before the Court. As another section of this Court has noted, the issue of BP’s failure to collect biomonitoring data is “irrelevant” because “the point of an expert on general causation is to explain whether the exposure to a particular chemical is capable generally of causing a certain health issue in the general population. It is not dependent on data from the particular incident at issue.” Burns v. BP Expl. & Prod., No. 17-3117, 2022 WL 2952993, at n. 5 (E.D. La. July 25, 2022) (Ashe, J.). Considering the above, the Court finds that continuing all scheduling deadlines and submission deadlines would not ameliorate the lack of general causation evidence to support Milsap’s claims. Accordingly, Milsap’s motion to continue is denied. IV. CONCLUSION For the reasons stated herein, IT IS ORDERED that the motion in limine to exclude the causation testimony of Dr. Jerald Cook is GRANTED; IT IS FURTHER ORDERED that the motion for summary judgment is GRANTED and Milsap’s claims are DISMISSED WITH PREJUDICE; 19 Case 2:17-cv-04451-LMA-MBN Document 67 Filed 08/15/22 Page 20 of 20 IT IS FURTHER ORDERED that Milsap’s motion to continue is DENIED. New Orleans, Louisiana, August 15, 2022. _______________________________________ LANCE M. AFRICK UNITED STATES DISTRICT JUDGE 20
