The Environmental Protection Agency (EPA) on Thursday ordered freight train operator Norfolk Southern to test for toxic pollutants that could have been released as a result of the company's decision to burn vinyl chloride from cargo on its derailed train in East Palestine, Ohio.
Why it matters: Norfolk Southern had at the time said that burning the cargo was necessary to prevent the threat of explosions from the hazardous materials in the train, but has since faced heightened scrutiny over the move and its possible impacts on the surrounding community and environment.
