Various residents of Scottsbluff, Nebraska (Plaintiffs) appeal from rulings by the district court
I.
On November 4, 2000, 18 cars from an 84-car freight train operated by BNSF derailed in Scottsbluff. Benzene and other hazardous chemicals from some of the derailed cars leaked to the air and ground. Approximately 1,100 Scottsbluff residents were evacuated.
An investigation into the derailment concluded that the accident originated with the coupler that connected car 33 to car 34.
Two days prior to the derailment, MRL employees had performed a federally mandated inspection of the freight cars at a rail yard in Laurel, Montana.
Plaintiffs filed various suits against BNSF and MRL in Nebraska state court. As relevant to this appeal, they alleged negligence (contending that MRL’s inspectors, as agents of BNSF, negligently inspected the train in Laurel), negligence per se (based on purported violations of federal environmental statutes), and strict liability (asserting that BNSF engaged in an ultrahazardous activity by transporting benzene through populated areas). BNSF and MRL removed the suits to federal court, and the district court consolidated the cases. After the district court dismissed the negligence per se and strict liability claims, Plaintiffs moved to amend their complaints to assert claims based upon a theory of res ipsa loquitur. The district court denied that motion. It then granted summary judgment in favor of BNSF and MRL on the negligence claims, concluding that those claims were preempted by federal regulations adopted pursuant to the Federal Railroad Safety Act (FRSA), 49 U.S.C. § 20101 et seq. Plaintiffs appeal from the dismissal of their negligence per se and strict liability claims, from the denial of their motion to amend their complaints, and from the grant of summary judgment on their negligent inspection claims.
II.
We review de novo the district court’s determination that a common law cause of action has been preempted by federal law. Chapman v. Lab One,
State law is preempted when it conflicts with or frustrates federal law. U.S. Const. art. VI, cl. 2; CSX Transp., Inc. v. Easterwood,
Laws, regulations, and orders related to railroad safety and laws, regulations,*793 and orders related to railroad security shall be nationally uniform to the extent practicable. A State may adopt or continue in force a law, regulation, or order related to railroad safety or security until the Secretary of Transportation (with respect to railroad safety matters), or the Secretary of Homeland Security (with respect to railroad security matters), prescribes a regulation or issues an order covering the subject matter of the State requirement. A State' may adopt or continue in force an additional or more stringent law, regulation, or order related to railroad safety or security when the law, regulation, or order—
(1) is necessary to eliminate or reduce an essentially local safety or security hazard;
(2) is not incompatible with a law, regulation, or order of the United States Government; and
(3) does not unreasonably burden interstate commerce.
49 U.S.C. § 20106 (2005).
In Easterwood, the Supreme Court concluded that legal duties imposed on railroads by the common law fell within the scope of the “broad phrases” of the FRSA’s preemption clause.
The Federal Railroad Administration (FRA) is authorized to “prescribe regulations and issue orders for every area of railroad safety.”
The regulations also establish a “national railroad safety program” intended “to promote safety in all areas of railroad operations in order to reduce deaths, injuries and damage to property resulting from railroad accidents.” Id. at § 212.101(a). Federal and state inspectors “determine the extent to which the railroads, shippers, and manufacturers have fulfilled their obligations with respect to inspection, maintenance, training, and supervision.” Id. at § 212.101(b)(1). Inspectors visit rail yards to ensure compliance with the regulations, id. at § 212.213, and railroads face civil
Plaintiffs contend that the FRA’s regulations do not substantially subsume the subject matter of their negligent inspection claims because the regulations do not specify the manner in which freight car inspections must be accomplished. But a regulatory framework need not impose bureaucratic micromanagement in order to substantially subsume a particular subject matter. Cf. CSX Trans., Inc. v. Williams,
III.
Plaintiffs contend that the district court erroneously applied Nebraska law rather than Montana law to their negligence per se and strict liability claims, resulting in an improper dismissal of those claims.
A.
A federal district court sitting in Nebraska must follow Nebraska’s conflict of law rules. Modern Computer Sys., Inc. v. Modern Banking Sys., Inc.,
Section 145 of the Restatement lists four “contacts” that should be considered in determining which state has the more significant relationship: (1) “the place where the injury occurred”; (2) “the place where the conduct causing the injury occurred”; (3) “the domicil, residence, nationality, place of incorporation and place of business of the parties”; and (4) “the place where the relationship, if any, between the parties is centered.” Id. at § 145(2). Contrary to Plaintiffs’ contentions, it is clear that the section 145 contacts favor applying Nebraska law to the state law claims. The injuries occurred in Nebraska. Both the strict liability claims (that the transport of benzene through Scotts-bluff was an ultrahazardous activity) and the negligence per se claims (that the release of chemicals after the derailment violated federal environmental statutes) assert that the conduct causing the injury, occurred in Nebraska. Most (if not all) of the plaintiffs are Nebraska residents. And the only relationship between the parties derives from the derailment, which occurred in Nebraska.
The section 145 contacts “must be balanced in accordance with their significance to the general principles under § 6(2)” of the Restatement. Malena,
B.
Having concluded that the district court correctly determined that Nebraska law applies to Plaintiffs’ strict liability and negligence per se claims, we turn to the district court’s dismissal of those claims, which we review de novo. Knouse v. Gen. Amer. Life Ins. Co.,
We agree with the district court’s conclusion that the violation of a regulation or statute is generally not recognized as negligence per se under Nebraska law. See Fuhrman v. State,
The Supreme Court of Nebraska has consistently declined to reach the question of strict liability when an insufficient evi-dentiary basis exists for concluding that a particular activity is ultrahazardous. See, e.g, Bargmann v. Soil Oil Co.,
The judgment is affirmed.
Notes
. The Honorable Richard G. Kopf, United States District Judge for the District of Nebraska.
. We refer to individual cars of the freight train by the numbering system used by the district court.
. BNSF has leased the Laurel Rail Yard to MRL since 1987. The lease requires MRL to perform inspections on BNSF trains at the Laurel yard.
. Plaintiffs also appeal the district court's denial of their motion for leave to supplement the disclosure of one of their experts, Karl Wolff. Because Plaintiffs concede that this aspect of their appeal is moot if we affirm the district court’s other rulings, see Plaintiffs’ Reply Br. at 27, we need not address it.
. Although the current version of the FRSA’s preemption clause is "worded slightly differently” than the version that the Supreme Court examined in Easterwood, we have noted that the two versions are "identical in substance.” Cearley v. Gen. Am. Trans. Corp.,
. The authority originates in the FRSA, which authorizes the Secretary of Transportation to "prescribe regulations and issue orders for every area of railroad safety.” 49 U.S.C. § 20103. The Secretary has delegated to the FRA the authority to "[c]arry out all functions vested in the Secretary by the [FRSA],” with certain exceptions not applicable here. 49 C.F.R. § 1.49(m).
. For this reason, we deny Plaintiffs' motion to supplement the record with a 1996 audit report by the Department of Transportation's Inspector General, tendered as evidence of the efficacy of the FRA's regulations. See Appellant's Motion for Judicial Notice at 2.
. Our holding obviates the need to review the district court's denial of Plaintiffs' motion to amend their complaint to assert res ipsa lo-quitur because the res ipsa claim also rests on a theory of inadequate inspection and is therefore preempted. See Proposed Amended Complaint (Appellants’ App. Vol. 19 at 3607) (alleging in claims I and II that “in the normal course of events, the failure of the coupler system which caused the derailment would not have occurred unless the defendant conducting the inspection and responsible for maintenance was negligent”).
. The only modern Nebraska case to the contrary is Oddo v. Speedway Scaffold Co., which held that a "[bjreach of the duty imposed by [a state statute governing scaffolding safety] constitutes negligence per se, not merely evidence of negligence.”
