Three additional chemicals have been identified by the U.S. Environmental Protection Agency following the train derailment in East Palestine. 

The EPA has posted a document to their website from Norfolk Southern that led to the finding of the addition chemicals, which they identified as ethylene glycol monobutyl, isobutylene and ethylhexyl acrylate. 

The EPA has sent a letter to Norfolk Southern, asking the company to take responsibility for the incident, and to reimburse the agency for clean up costs and monitoring for those chemicals. 

In the letter from the EPA addressed to Norfolk Southern, the agency says that the chemicals from the train derailment continue to be released into the air and surface waters. 

According to the EPA, Norfolk Southern has to respond to the organization by the end of the day Monday about the additional chemicals.
