East Palestine, Ohio Train Derailment: Cause, Health, and Settlements

The East Palestine, Ohio train derailment happened on the evening of February 3, 2023, when a Norfolk Southern freight train carrying hazardous chemicals came off the tracks in the small village near the Pennsylvania border, leading to a controversial burn of vinyl chloride, a mandatory evacuation, and years of cleanup, litigation, and federal safety debate that are still unfolding. Thirty-eight of the train’s 149 cars derailed. Eleven of those carried hazardous materials. No one was killed, but the fallout has reshaped rail safety policy, produced a $600 million class-action settlement, and drawn a $310 million federal enforcement package that is still awaiting final court approval.

What Happened on February 3, 2023

At about 8:55 p.m., Norfolk Southern train 32N derailed at milepost 49.5 on the Fort Wayne Line, roughly a quarter-mile west of the Ohio-Pennsylvania state line.¹ Of the 38 cars that left the tracks, 11 were tank cars carrying vinyl chloride, butyl acrylate, ethylhexyl acrylate, ethylene glycol, and isobutylene.² Three tank cars were breached in the derailment itself, feeding a fire that damaged 12 more cars.

No one died and no one was hurt in the derailment itself. Norfolk Southern later reported 24 minor injuries from inhalation hazards during the fire and cleanup: 18 civilians and 6 remediation contractors.¹ Ohio Governor Mike DeWine ordered a mandatory evacuation that stayed in effect for roughly two weeks.

The Vent and Burn Decision

Three days after the derailment, on February 6, 2023, the local incident commander ordered a “vent and burn” of five tank cars carrying vinyl chloride monomer. East Palestine fire chief Keith Drabick was given 13 minutes to approve it.³ The burn produced a towering black plume visible for miles. Burning vinyl chloride breaks down into carbon monoxide, hydrogen chloride, and phosgene gas. The hydrogen chloride byproduct killed an estimated 3,500 fish in local waterways.⁴ Precipitation data later showed pollution from the plume reached 16 states.⁵

The National Transportation Safety Board later determined the vent and burn was unnecessary. Norfolk Southern and its contractors had told the incident commander the tank cars were at imminent risk of a polymerization-induced explosion, but the NTSB found that claim was unsupported. The tank car manufacturer, OxyVinyl, had inspected the cars, found a low risk of explosion, and reported the cars were cooling. Norfolk Southern did not pass that information along.⁶ NTSB Chair Jennifer Homendy called Norfolk Southern’s conduct during the investigation “unprecedented” and “reprehensible.”³

Why the Train Derailed

The NTSB completed its investigation in June 2024 and issued report RIR-24-05 with 34 safety recommendations.⁶ The probable cause was an overheated wheel bearing on the train’s 23rd car, a hopper car, that failed and separated the axle. The post-derailment fire likely started when a flammable liquid spilled from a punctured DOT-111 tank car.⁷

Several factors made the disaster worse. The train had passed a wayside hot bearing detector that flagged the failing bearing, but the alert was low-priority, and the NTSB found these detectors are inherently limited and often produce misleadingly low readings. Detector spacing on Norfolk Southern’s network and the company’s operating procedures kept the crew from receiving enough warning to stop in time. The older DOT-111 tank cars still in hazardous materials service have a lower survival rate in derailments than newer designs. Norfolk Southern also delayed sending the train consist — the manifest identifying what each car carried — to emergency responders, and the hazmat placards on the cars burned away in the fire.⁷

Health Effects and Ongoing Research

In the weeks after the derailment, residents reported headaches, respiratory irritation, skin and eye irritation, and anxiety.⁸ The CDC’s Agency for Toxic Substances and Disease Registry surveyed 701 people between February 21 and March 31, 2023. Of those, 86% reported exposure to hazardous substances, 92% reported at least one new or worsening physical symptom, and 70% reported at least one new or worsening mental health symptom. Forty-four percent said they had unmet needs, most commonly for clean water. The findings supported the creation of a permanent health clinic in the village.⁹

A survey of 114 Pennsylvania first responders found that firefighters and those involved in fire suppression were more likely to report vapor and gas contact, which was associated with higher rates of multiple symptoms.¹⁰ Blood sampling of 18 East Palestine residents showed dioxin levels consistent with those expected in the general U.S. population.¹¹

For longer-term answers, the National Institutes of Health committed $10 million over five years to the East Palestine Train Derailment Health Research Program. The consortium includes the University of Kentucky, the University of Pittsburgh, Yale, Ohio State, Case Western Reserve, Texas A&M, and UC San Diego. Its work covers long-term health outcomes, biological markers of risk, and the effects of chemical exposure on DNA damage and organ function.¹²⁸ Results will take years.

Cleanup and Water Safety

EPA personnel have been on-site since the night of the derailment. The agency describes the cleanup as nearing completion, with long-term monitoring continuing.² Independent monthly testing by the Ohio EPA has found no contaminants associated with the derailment in the village’s municipal drinking water, and vinyl chloride has not been detected in the municipal supply or any water supply wells.¹³ A new filtration system was installed at the village water plant in June 2024.¹⁴ Residents on private wells are advised to have their water tested independently, because municipal results do not cover private systems.

Surface water has improved substantially. Butyl acrylate in Sulphur Run dropped from a post-derailment peak of 154,000 parts per billion to a final detection of 1.1 ppb on April 8, 2023. After more than 4,200 samples, the monitoring program transitioned in June 2024 to long-term monthly sampling focused on Sulphur Run and Leslie Run. Biological monitoring in 2023 indicated Leslie Run had recovered to pre-derailment conditions.¹⁴

Cleanup data itself has come under scrutiny. In September 2025, the EPA identified discrepancies in groundwater sampling data for 2-butoxyethanol. Analysts at ALS Houston, a subcontractor to the prime cleanup contractor Tetra Tech, had been altering measurements. Independent testing at the EPA’s PHILIS laboratory confirmed no 2-butoxyethanol was present. In February 2026, Tetra Tech notified the EPA of the altered measurements and the subcontractor terminated two analysts.¹⁵ The EPA rejected all data from ALS Houston, referred the matter to its Office of Inspector General, and stated that none of the falsified data was used in any health, safety, cleanup, or enforcement decisions.¹⁶

Lawsuits and Settlements

The $600 Million Class-Action Settlement

Norfolk Southern reached a $600 million class-action settlement covering residents and businesses within 20 miles of the derailment site.¹⁷ The case, In re East Palestine Train Derailment (No. 4:23-cv-00242), is before Judge Benita Y. Pearson in the U.S. District Court for the Northern District of Ohio. Final approval was granted on September 27, 2024, and the U.S. Supreme Court denied the final petition for certiorari on March 2, 2026, clearing the way for payments.¹⁸ The class covers roughly 55,000 members.

Settlement administrator Epiq mailed personal injury award payments on March 31, 2026. Direct household payments are anticipated by the end of June 2026, and business loss claims are expected later in 2026.¹⁹ Categories covered include property damage, displacement expenses, lost wages, business income loss, diminution of property value, emotional distress, and increased risk of disease. Class members within 10 miles of the derailment who signed additional personal injury releases may receive additional compensation. Some class members have voiced frustration that payments are smaller than they expected.¹⁷

The $310 Million Federal Consent Decree

In March 2023, the United States filed a Clean Water Act complaint against Norfolk Southern. In May 2024, the Justice Department and EPA announced a settlement valued at more than $310 million.²⁰ The package requires Norfolk Southern to pay roughly $235 million for past and future cleanup, $25 million for a 20-year community health program, $15 million for 10 years of groundwater and surface water monitoring, $15 million for a private drinking water well monitoring program, about $6 million for waterways remediation of Leslie Run and Sulphur Run, a $15 million civil penalty, and $175,000 for natural resource damages.²¹ As of May 2026, the proposed consent decree is still pending before the court; the DOJ filed a motion in October 2024 asking the judge to finalize it.²² The federal consent decree also includes a medical monitoring program that is separate from and not part of the class-action settlement.¹⁸

Ohio’s Separate Lawsuit

On March 14, 2023, Ohio Attorney General Dave Yost filed a 58-count civil suit against Norfolk Southern alleging violations of federal and state environmental laws, including CERCLA and Ohio’s hazardous waste and water pollution statutes, along with negligence, public nuisance, and trespass claims. The complaint asserted that over one million gallons of hazardous chemicals were released into local waterways.²³ Ohio is not a party to the federal consent decree and is pursuing its own settlement or trial, with the possibility of seeking different and additional relief.²⁴

Norfolk Southern’s Total Exposure

Norfolk Southern estimates its total spending on the derailment — cleanup, settlements, and rail safety improvements — will exceed $1 billion. That includes roughly $780 million in environmental response costs already incurred and an estimated $200 million or more in safety enhancements.²⁵

Property Values and Local Economy

A December 2025 study in the Journal of Sustainable Real Estate found that residential property values in the area covered by Norfolk Southern’s Value Assurance Program dropped by about 14% compared to control communities, with estimates ranging from 12.8% to 15.8%. Affected homes stayed on the market roughly 25% longer than comparable properties elsewhere. The analysis covered more than 3,000 sales from 2018 to 2024.²⁶ Norfolk Southern’s Value Assurance Program offered to reimburse homeowners for lost value, but participants were required to waive the right to sue the company for further property-related damages.²⁷

The Ohio Department of Development created a forgivable loan program for businesses within a two-mile radius, offering 0% interest loans of $10,000 to $1 million for payroll, rent, utilities, and inventory. The village also designated its entire footprint as a Community Reinvestment Area, providing property tax exemptions of up to 15 years on new construction or renovation.²⁸

What Is Still Unresolved

More than three years on, several major pieces of the East Palestine story are still open. The federal $310 million consent decree awaits final court approval. Ohio’s state lawsuit is unresolved. The NIH’s five-year health study is underway and results will take time. And the Railway Safety Act, first introduced in the 118th Congress as S. 576, stalled without a floor vote. As of May 2026, its provisions have been folded into the BUILD America 250 Act (H.R. 8870), which cleared the House Transportation and Infrastructure Committee on May 22, 2026, with bipartisan support. Committee leadership wants the bill to reach the President before the current surface transportation authorization expires on September 30, 2026.²⁹ No rail safety legislation has been enacted since the derailment occurred in February 2023.³⁰

The NTSB called for an accelerated phaseout of DOT-111 tank cars, but that timeline is set by the FAST Act. Under the current schedule, DOT-111 cars must be replaced with modern DOT-117 models by May 1, 2025, for the most dangerous Packing Group I flammable liquids, and by May 1, 2029, for Packing Group II and III materials, with possible extensions to 2027 and 2031 if shop capacity is insufficient.³¹ PHMSA and the FRA have encouraged owners to retire older cars sooner but acknowledged they lack authority to override the congressional deadlines.³²
