EPA asks inspector general to review East Palestine derailment response
The Environmental Protection Agency said Friday, August 28, 2026, that Vice President JD Vance and EPA Administrator Lee Zeldin asked the agency’s Office of Inspector General to conduct a comprehensive, independent review of the federal response to the February 3, 2023, Norfolk Southern train derailment in East Palestine, Ohio.
EPA said the requested review would examine decisions and actions by federal, state and private entities after the derailment. The agency cited continuing community concerns about health, air, soil, water, contamination and the decisions made during the response.
The request is not an inspector general finding, criminal charge or final determination that the Biden administration, Ohio officials or Norfolk Southern violated law or policy. EPA also has not announced that the OIG has accepted or completed the requested review.
What the request covers
EPA described the proposed review as broad. It would examine the response after the derailment, including the decisions and coordination involving government agencies and private entities. The agency said the review is intended to provide accountability and inform future actions if investigators identify shortcomings.
That could include scrutiny of the emergency response, the controlled release and combustion of hazardous materials, environmental monitoring, public communication and how health concerns were handled. Those are potential areas of review, not findings that misconduct occurred.
The EPA announcement does not establish a timeline for the OIG’s decision or for any eventual investigative work. The scope and schedule would depend on the inspector general’s actions.
EPA separately cited groundwater-data problems
The agency also pointed to a separate data-quality issue announced March 2, 2026. EPA said subcontractor analysts working on fall 2025 groundwater samples altered measurements involving 2-butoxyethanol, a solvent used in some household and industrial products.
EPA said confirmatory testing at other laboratories did not detect the chemical and that the rejected data were not used for health, safety, cleanup or enforcement decisions. The agency said the prime contractor terminated two analysts after determining that they had failed to follow standard operating procedures.
EPA said it rejected the data, expanded quality-control measures and referred the data-quality issue to its inspector general. The agency also said past and current data showed no ongoing groundwater risk from 2-butoxyethanol in East Palestine.
That sampling matter is separate from the broader oversight request announced Friday. The available EPA records do not establish that the OIG has opened a single, comprehensive review of the derailment response.
What the NTSB already found
The National Transportation Safety Board’s investigation into the derailment is complete. The NTSB determined that the probable cause was the failure of an overheated wheel bearing, which caused an axle to separate and derailed the train.
The February 3, 2023, derailment involved 38 mixed freight railcars. The train included tank cars carrying hazardous materials, and emergency responders established a one-mile evacuation zone that affected about 2,000 residents. The NTSB said no injuries were reported during the derailment or emergency response.
The NTSB also found that Norfolk Southern and its contractors failed to communicate relevant expertise and dissenting opinions to the incident commander. It said inaccurate information about the risk of a chemical reaction created unwarranted urgency and led to what the agency described as an unnecessary decision to vent and burn five derailed vinyl chloride tank cars.
The board issued 34 new recommendations to federal agencies, Ohio, emergency-management organizations, industry groups and Norfolk Southern. Those findings address the mechanical cause of the derailment and transportation-safety aspects of the emergency response. They are separate from any future EPA inspector general review of administrative oversight, environmental response or data-quality practices.
What East Palestine residents should watch next
The next significant developments will be whether the EPA Office of Inspector General confirms or accepts the request, how the review is defined and whether investigators issue findings or recommendations.
Friday’s announcement does not by itself change cleanup plans, compensation, public-health guidance or liability findings. Until EPA announces otherwise, the agency’s existing East Palestine cleanup, monitoring and public-health information remains the relevant source for current site conditions.
