The EPA issued an internal memo warning of “substantial threat to public health and the environment” from the East Palestine train derailment just 10 days after telling residents it was safe to return home

The internal warning contradicted public statements from EPA Administrator Michael Regan, who told residents two weeks after the Feb. 3, 2023, derailment that “all families need to know that they are safe” and that air monitoring had not detected health concerns in the community. 

Despite the internal concerns, the EPA encouraged residents to return home after a three-day evacuation and maintained publicly that the area was safe.
