Nonnon v. City of New YorkNonnon v. City of New York
OPINION OF THE COURT
Thеse consolidated actions are for personal injuries and wrongful deaths allegedly arising from plaintiffs’ exposure to hazardous substances emanating from the Pelham Bay landfill in the Bronx. On a previous appeal, affirming the denial of defendants’ motions to dismiss, inter alia, for failure to state a cause of action, we determined that plaintiffs’ expert evidence did not require that a hearing be held in accordance with Frye v United States (293 F 1013 [DC Cir 1923]) (
The now inactive 81-acre Pelham Bay landfill is owned by the City and was operated by the Department of Sanitation (DOS) beginning in 1963 for the disposal of 2,600 tons of municipal solid waste per day. Over the years, surrounding residents complained about odors and the improper and illegal dumping of hazardous materials and industrial waste from corporations in the area. The landfill was ordered to close on December 31, 1978.
In March оf 1985, the City commenced an action under the federal Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (42 USC, ch 103, § 9601 et seq.) against 15 corporate defendants. The City claimed that the corporations had illegally disposed of industrial and chemical
In 1985, DOS signed а consent decree with the State Department of Environmental Conservation (DEC), in which it admitted that it had allowed hazardous waste to be illegally disposed at the landfill while it was in operation, and that it had allowed leachate to enter the surface and ground waters in violation of state and federal standards (Nonnon I,
Between 1991 and 1993, nine separate actions were brought against the City by residents of the neighborhoods closest tо the landfill (Nonnon I,
On September 29, 2000, the City moved to dismiss the nine actions for failure state a cause of action, asserting, inter alia, that plaintiffs had failed to allege or establish a viable causal connection between the landfill and their injuries (Nonnon I,
The motion court rejected the City’s argument that the claims should be dismissed for failure to state a cause of action. The court found that the City’s citation of reports pertaining to the Frеsh Kills landfill, located on Staten Island, had no applicability to the case at bar, and that the City had offered no other evidence in support of its assertion that plaintiffs had failed to as
This Court affirmed, rejecting the City’s argument that the scientific methodologies employed by plaintiffs’ experts were insufficient to establish that plaintiffs’ cancers were caused by exposure to substances emanating from the landfill (Nonnon I,
After this Court granted leave to appeal, the Court of Appeals affirmed on the ground that the City’s motion had never been converted to one for summary judgment and plаintiffs, therefore, “were not put on notice of their obligation to make a complete record and to come forward with any evidence that could possibly be considered” (Nonnon I,
On or about October 12, 2007, the City filed a motion for summary judgment.
The 1993 Woodward-Clyde report discussed exposure pathways and noted that for area residents, both adults and children, the potential carcinogenic risks posed by inhalation of volatile organic compounds (VOCs) were below the risk level considered negligible by the Environmental Protection Agency (EPA) in setting cleanup goals under Superfund. The potential carcinogenic risks posed by incidental ingestion and dermal absorption from landfill soils were elevated for both workers and youth trespassers, but within the acceptable risk levels used by EPA in setting Superfund cleanup goals.
The City relied on the affidavit of Dr. Kara Kelly, M.D., a pediatric oncologist, who concluded that “no known medical or scientifiс basis exists for plaintiffs’ claim that exposure to chemicals in the Pelham Bay Landfill, assuming such exposure occurred, caused them to develop ALL.”
The City also relied on a new affidavit from its expert Dr. Jonathan Borak, M.D., who opined that no causal link between proximity to the landfill and plaintiffs’ cancers could be scientifically established. Dr. Borak claimed, based on a review of the scientific literature, that there is no credible evidence linking childhood ALL to any specific chemical.
Plaintiffs, in opposition, relied on the evidence contained in the prior record on appeal (discussed extensively in this Court’s opinion in Nonnon I [
Dr. Richard Neugebauer, an epidemiologist, opined that persons residing in close proximity to the landfill experienced higher incidence rates of acute lymphoblastic leukemia as compared with persons residing further away from the landfill, and concluded that the landfill “is, more likely than not, a cause of the increased rates of childhood leukemia among area residents.”
Dr. Neugebauer’s study defined four rings, or bands, located 8,000, 12,000, 16,000 and 20,000 feet, respectively, from the landfill center. He obtained, from the cancer registry, the age, gender and racе breakdown in each of the census tracts.
When these adjustments were made, the rate of childhood ALL in Band 1 was more than fourfold higher and statistically significantly greater, with a SMR of 4.05, than the rate among persons in Band 4. The rate of childhood ALL among persons in Band 2 was similarly substantially and statistically significantly elevated, with an SMR of 5.2, as compared to persons in Band 4. (The SMR for persons living in Band 3 as compared to Band 4
Dr. Neugebauer opined that in this case proximity analysis was the “optimal design,” with distance from the landfill a proxy for the measure of exposure. Dr. Neugebauer noted that numerous epidemiological studies had investigated a possible disease excess around a point source of contamination by drawing concentric rings at increasing radial distance from the source and by obtaining data on the number of cancer cases per ring. Dr. Neugebauer stated that the superiority of this type of proximity analysis was “well-established.” If the test for a linear trend was statistically significant, the proper conclusion is that a dose-response relationship exists.
Dr. Neugebauer also reanalyzed the Borak study, using six bands rather than seven,
Plaintiffs also relied on the affidavit of Dr. Bruce K. Bernard, an expert toxicologist and biostatistician. In order to determine the general plausibility of a cause-and-effect relationship between an increase in the observed frequency of childhood ALL and exposure to chemicals emanating from the landfill, Dr. Bernard analyzed Dr. Neugebauer’s findings using the evaluation scheme propounded by Sir Austin Bradford Hill, a well-known epidemiologist and biostatistician. Hill’s approach involves analysis of nine factors: (1) strength of association, (2) consistency, (3) specificity, (4) temporality, (5) biological gradient, (6) biological plausibility, (7) coherence, (8) experiment, and (9) analogy.
Dr. Bernard found that strength of association was clearly demonstrated by comparisons between Band 1 and Band 2 versus Band 4, showing a very significant relationship between
Dr. Bernard aсknowledged that epidemiological data was more limited since environmental, occupational and health data limited exposure to these toxic substances. Dr. Bernard noted that human health data on these substances was largely derived through occupational exposures (which, by definition, would exclude children) and the rare accident or case of malfeasance. Dr. Bernard opined that within these scientific and moral constraints, available data was consistent with the cause-and-effect hypothesis.
Dr. Bernard opined that there was high specificity in thé case of the causal relationship between the landfill and childhood ALL. He noted that thе proposed causal relationship was limited by age (i.e., children), general disease type (i.e., cancer), specific system (i.e., hematopoietic), disease entity .(i.e.; ALL) and distance from the landfill (i.e., bands).-
As to temporality, Dr. Bernard noted that none of plaintiffs were diagnosed with their illnesses before dumping began and all lived in close proximity to the landfill.
As to biological gradient, Dr. Bernard opined that the data demonstrated a direct dose-response relationship between exposure and the disease.
Dr. Bernard noted that “biological plausibility” (i.e., the notion that the proposed causal relationship should not seriously conflict with the breadth of generally accepted facts of the underlying science), was a question which turned on the etiology of childhood ALL, knowledge about chemicals in and leaching from the landfill, the potential human.exposure to those chemicals and the known latency period for the development of childhood ALL. Dr. Bernard opined that available evidence supported a causal relationship between childhood ALL and exposure to a wide variety of substances, including ionizing radiation, pesticides, and organic solvents, such as benzene,
As to coherence, Dr. Bernard opined that he was unaware of a conflict between the proposed relationship (i.e., an increase in childhood ALL and the chemicals dumped in and around the landfill) and established scientific data.
As to “experiment” (i.e., the notion that if A causes B, we should be able to decrease the occurrence of B by removing A), Dr. Bernard stated that he was unaware whether this data was available or had been analyzed.
Finally, as to analogy, Dr. Bernard noted that the Woburn case, although involving a different pathway, namely, drinking water, concerned exposure to the same chemicals involved in this case and the same medical sequelae.
Upon analysis of Hill’s nine factors, Dr. Bernard concluded, with a reasonable degree of toxicological certainty, that it was more likely than not that exposure to chemicals emanating from the landfill was the cause of the increased frequency of childhood ALL observed in the plaintiffs.
Dr. Diane Trainor, Ph.D., an occupational and health and safety expert, studied the history of the landfill and analyzed possible exposure pathways. Dr. Trainor noted that it could not seriously be disputed that known toxic substances, long associated with ALL and Hodgkin’s diseаse, had made their way into the air, ground and water, and that plaintiffs had been exposed to these substances through swimming in Eastchester Bay, eating fish from the bay, ingestion and dermal contact with landfill soils, contact with leachate seeps on sidewalks and jogging trails, eating items grown at a public vegetable garden adjacent to the landfill, and breathing the air in the vicinity of the landfill.
Finally, Dr. Philip Lanzkowsky, M.D., opined that numerous studies had found a statistically significant relationship be
The motion court denied the City’s motions for summary judgment in all nine aсtions, stating that “in the instant motion, the City raises no new facts or law to warrant a departure from the prior holding of the Appellate Division, First Department [in Nonnon I]” (
The Frye test is not concerned with the reliability of a particular expert’s conclusions, but rather, with “whether the expert[’s] deductions are based on principles that are sufficiently established to have gained general acceptance as reliable” (Nonnon I,
As we observed in Nonnon I, epidemiology and toxicology are hardly novel sciences, but rather, well-established and accepted methodologies. In such a case, “the focus moves from the general reliability concerns of Frye to the specific reliability of the procedures followed to generate the evidence proffered and whether they establish a foundation for the reception of the evidence at trial” (Parker v Mobil Oil Corp.,
An expert opinion on causation should set forth a plaintiffs exposure to a toxin, that the toxin is capable of causing the particular illness (i.e., general causation), and thаt the plaintiff was exposed to levels of the toxin sufficient to cause illness (i.e., specific causation) (Parker,
Epidemiology is the study of disease patterns in human populations. It uses studies “to observe the effect of exposure to a single factor upon the incidence of disease in two otherwise identical populations,” seeking to associate unusual patterns of disease with environmental or biological risk factors (Black and Lilienfeld, Epidemiologic Proof in Toxic Tort Litigation, 52 Fordham L Rev 732, 755 [1984]). Eрidemiological studies do not
Dr. Neugebauer opined that the rate of childhood ALL in Band 1 was more than fourfold higher and statistically significantly greater, with an SMR of 4.05, than the rate among persons in Band 4. The rate of childhood ALL among persons in Band 2 was similarly substantially and statistically significantly elevated, with an SMR of 5.2, as compared to persons in Band 4. Dr. Neugebauer noted that the probability that this pattern of increаses in rates with increasing proximity to the landfill arose from random error was 1 in 10,000. Dr. Bernard similarly opined that the strength of association was clearly demonstrated by comparisons between Band 1 and Band 2 versus Band 4, showing a very significant relationship between the incidence of childhood ALL and proximity to the landfill.
The City contends that it is impossible to establish specific causation because plaintiffs cannot quantify their exposure to any specific toxin. The City insists that in the absence of a specific dose-response .analysis, plaintiffs cannot establish that their current ailments were caused by toxins emanating from the landfill. We disagree. In Parker v Mobil Oil Corp. (
Thus, so long as plaintiffs’ experts have provided a “scientific expression” of plaintiffs exposure levels, they will have laid an adequate foundation for their opinions on specific causation (Jackson,
Here, Dr. Bernard оpined that the strength of the association was consistent with a cause-and-effect relationship between the landfill and childhood ALL and that the data demonstrated a direct dose-response relationship between exposure and the disease. He further opined that the available evidence concerning “biological plausibility” supported a causal relationship between childhood ALL and exposure to a wide variety of substances, including ionizing radiation, pesticides, and organic solvents, such as benzene, found to have emanated from the landfill. Dr. Bernard noted that etiologies believed to be associated with the induction of leukemias, inсluding childhood leukemias, have as their common mechanism mutagenic effects on chromosomal tissue.
Given that the City relied on the proximity analyses contained in DOH’s 1988 and 1994 studies of the landfill, it must concede that proximity analysis is a recognized substitute for a dose-response analysis. Dr. Neugebauer explained that the purpose of his study was to test the hypothesis of DOH’s scientific advisory committee that if an epidemiological study of the landfill were extended into the 1990s and specifically looked at ALL, it might show an increased risk of ALL with increasing proximity to the landfill.
Furthermore, and critically, in this case, the strength of the epidemiological data alone permits an inference оf causation. The Federal Reference Manual on Scientific Evidence notes that courts have permitted an inference of specific causation where the relative risk in an epidemiological study is greater than 2.0 {see Green, Freedman and Gordis, Reference Guide on Epidemiology, in Federal Judicial Center, Reference Manual on Scientific Evidence, at 384 [2d ed]). “When the relative risk reaches 2.0, [an] agent is responsible for an equal number of cases of disease as all other background causes” {id.) Thus, a
In this case, the relative risks in Bands 1 and 2 were 4.05 and 5.2, respectively, when adjusted for confounding factors, well in excess of 2.0. Thus, according to the Federal Reference Manual, at least as to those plaintiffs suffering from ALL,
The City’s criticisms of Dr. Neugebauer’s study go to the weight of the evidence, not its admissibility. As the Court of Appeals stated in People v Wesley (
While the strength of the epidemiological evidence, alone, is sufficient for plaintiffs to establish that substances emanating from the landfill are more likely than not the cause of childhood ALL, those plaintiffs suffering from Hodgkin’s disease put forth no similar evidence. Thus, we are constrained to dismiss the claims of plaintiffs Nessen and Walsh.
Plaintiffs, residents of the neighborhoods surrounding the landfill, were exposed to toxins, including benzene, over a number of years, via air emissions and contact with contaminated soil and/or contaminated surface and ground waters. Each of the plaintiffs lived in close proximity to the landfill. They рlayed in a park adjacent to the landfill, swam and fished in Pelham Bay, and ate locally grown vegetables. It is undisputed that over a period of several decades, known carcinogens were disposed of at the landfill. The presence of these carcinogens,
We recognize that in toxic tort cases it is always difficult to prove specifiс causation. But as plaintiffs expert toxicologist noted, this is a “standard problem” in environmental exposure cases. The Court of Appeals in Parker acknowledged this difficulty, specifically holding that “it is not always necessary for a plaintiff to quantify exposure levels precisely or use the dose-response relationship,” provided that his or her expert uses acceptable alternative methods to estimate exposure to a toxin (
Accordingly, the orders, Supreme Court, Bronx County (Larry S. Schachner, J.), entered on or about April 26, 2010 and April 27, 2010, which, respectively, denied defendant City of New York’s motions for summary judgment dismissing the complaints of the Nessen and Walsh plaintiffs, should be reversed, on the law, without costs, the motions granted and the complaints dismissed. The Clerk is directed to enter judgment accordingly. The orders of the Supreme Court (Larry S. Schachner, J.), entered on or about June 18, 2009, April 26, 2010, and April 27, 2010, which denied defendant’s motions for summary judgment dismissing the complaints of the plaintiffs other than the Nessen and Walsh plaintiffs, should be affirmed, without costs.

Notes
. This Court consolidated the nine actions for purposes of filing a single appellate brief and record.
. The City filed the same motion for summary judgment in all nine cases. However, unbeknownst to the City the eight cases other than Nonnon had already been dismissed by the Clerk of the Court, apparently due to a misapprehension about the apрlicability of Nonnon I to the eight related actions. The City and plaintiffs’ counsel thereafter stipulated to the applicability of Non-non I to all of the actions and to reinstatement of the eight related cases that had inadvertently been dismissed. The City then moved for summary judgment in the eight related actions, relying on the motion for summary judgment previously filed, dated October 12, 2007.
. The study noted that while “excesses” in overall leukemia rates were not found, two findings indicated a possible increased incidence of childhood leukemia, including a statistically significant excess of cases reported in district 4 in the year 1984, and an excess of cases in 4 of the 162 census tracts in districts 4 and 6.
. The City complains that it lаcked access to Dr. Neugebauer’s data. Dr. Neugebauer stated that he obtained the relevant information regarding childhood ALL cases from the cancer registry and the City certainly cannot dispute that it had access to this same data. Dr. Neugebauer’s affidavit also describes the manner in which he defined the four bands used in his proximity analysis, and the adjustments made to the data to account for age, gender, race and location, all standard adjustments. Dr. Neugebauer states that he obtained data concerning the size of the pediatric population in each of the census tracts and the age, gender and race breakdown from publicly available data from the U.S. Census Bureau, information equally available to the City. Dr. Neugebauer stated that he presented standardized morbidity ratios (SMRs) with a 95% confidence interval. The information furnished by Dr. Neugebauer regarding his methods and data was sufficient for another expert to attempt to replicate his results.
. Dr. Neugebauer noted that a judicial ruling prevented access to the same type of data for the county of the Bronx, as a whole, and for the remainder of New York City, precluding comparison to the rates in New York City as a whole.
. An SMR of 1.0 would indicate that a given band nearer the landfill has approximately the same cancer incidence rate as the band furthest away; an SMR greater than 1.0 indicates that a given band nearer the landfill has a higher incidence rate than the band furthest away. An SMR of 2.0, for example, would indicate that the incidence of cancer in the band is two times greater than the rate in the band furthest away from the landfill. An SMR with a 95% confidence interval that excludes one is statistically significant at p < .05.
. Dr. Neugebauer excluded these outlying bands when he reanalyzed the data because Borak had excluded from Bands 6 and 7 those persons who did not reside in health districts 4 and 6, effectively eliminating 70% and 95%, respectively, of the population of those bands from his proximity analysis.
. Dr. Bernard noted that he would have liked to have a better estimate оf the actual exposure of the population to these substances, but noted that this was a “standard problem” in environmental exposure cases. Dr. Bernard noted that (1) data showed these substances to he emanating from the landfill at levels exceeding regulatory thresholds years after dumping had ceased, (2) well-known biodegradation rates existed for these substances, and (3) frequency dose-response curves, i.e., multiple points that demonstrate an increase in frequency of ALL the closer one gets to the landfill, existed for these substances.
. However, for those plaintiffs suffering from Hodgkin’s disease, the record does not contain epidemiological data sрecifically linking the development of that disease to substances emanating from the landfill. Plaintiffs expert Dr. Landzkowsky cites an article entitled “Chronic exposure to benzene as a possible contributory etiologic factor in Hodgkin’s Disease,” but does not discuss the findings of the study or otherwise address the strength of the association between the incidence of Hodgkin’s disease and exposure to benzene. We are thus constrained, as discussed below, to dismiss the claims of the two plaintiffs suffering from Hodgkin’s disease.
. As indicated above in footnote 9, Dr. Neugebauer’s epidemiological study pertains only to the increased incidence of childhood ALL with proximity to the landfill. It does not address Hodgkin’s disease.
