 \nOn February 3, 2023, a Norfolk Southern freight train derailed in East Palestine, Ohio  \nTwenty of the affected rail cars contained hazardous materials, including vinyl chloride, ethylene glycol, ethylhexyl acrylate, butyl acrylate and isobutylene  \nU.S. EPA staff arrived hours after the derailment and started monitoring the air for volatile organic compounds  \n(VOCs)  \nU.S. EPA contractors installed boomsand underflow dams to try and restrict the flow of contaminated water and collect floating material to lessen any possible impacts to the nearby Sulphur Run and Leslie Run streams  \nVinyl chloride in the derailed rail cars was considered unstable due to a drop in temperature discovered on Sunday night, February 5, 2023  \nAccording to Norfolk Southern, the pressure relief valves had stopped working on some of the cars, putting them at risk of exploding; Norfolk Southern made the decision to do a controlled release of the material into trenches dug in the ground where flares were lined up to ignite the chemical and burn it off  \nPrior to the controlled burn, the governors of Ohio and Pennsylvania ordered an immediate evacuation of a 1-mile-by-2-mile area covering the eastern part of East Palestine and the Darlington area of Pennsylvania in Beaver County  \nMONITORING AND SAMPLING BEGAN IMMEDIATELY  \n􀂃 The derailed train caused a cascade of activity  \n􀂃 Emergency response workers were first on the scene, followed by officials and workers associated with a variety of federal and state agencies and representatives  \n􀂃 Emergency response workers focused on addressing immediate hazards posed by the derailment  \n􀂃 As part of the emergency response, federal and state agency responders also began extensive environmental monitoring (air, soil, surface water, sediment and biological [plants, fish])  \n􀂃 As part of ongoing studies to evaluate the derailed train impacts to human health and the environment, independent researchers conducted studies largely focused on determining effects to the community  \n􀂃 U.S. EPA made technical assistance available to the village of East Palestine  \n|  |\n| --- |\n|  |\n| ROLE OF TASC SUPPORT\u003Cbr>|\n|  |\n\nROLE OF TASC SUPPORT  \n􀂃 U.S. EPA provided support to the East Palestine officials through U.S. EPA's Technical Assistance Services for Communities (TASC) program  \n􀂃 East Palestine officials wanted help in understanding the large amount of environmental data produced following spill/controlled burn  \n􀂃 TASC conducted an in-depth environmental data review, produced areport and fact sheet, briefed local officials, and hosted a community webinar  \n􀂃 TASC also reviewed City Park soils data  \ncollected 7  \nROLE OF TASC SUPPORT  \n􀂃 Groups continued to collect data and conduct analysis in 2024  \n􀂃 East Palestine officials requested TASC to review and consolidate  \nthis information as new information becomes available  \n􀂃 East Palestine officials also requested a summary of other studies underway or being planned by other groups (not public agencies)  \n8  \n\n|  |\n| --- |\n| UPDATES ON EAST PALESTINE ENVIRONMENTAL DATA |\n| AVAILABLE AUGUST 2023-\u003Cbr>APRIL 2024\u003Cbr>|\n|  |","cbCaia0EcBH98aOt","https://ap.wps.com/l/cbCaia0EcBH98aOt","pdf",5680028,53,"English","# Agenda\n## Welcome\n## Background and Role of TASC Support\n## Updates on East Palestine Environmental Data Available August 2023 - April 2024\n## Questions and Discussion\n## Independent Environmental and Public Health Studies Completed, Underway or Planned\n## Questions and Discussion\n# Background\n## What Happened?\n## Monitoring and Sampling Began Immediately\n# Role of TASC Support\n# Updates on East Palestine Environmental Data Available August 2023 - April 2024","[{\"question\":\"What caused the East Palestine incident and why was a controlled burn used?\",\"answer\":\"On February 3, 2023, a Norfolk Southern freight train derailed in East Palestine, Ohio.
