The controversial decision to blow open those vinyl chloride cars and burn the toxic plastic ingredient generated a huge plume of black smoke over the Ohio town and fueled lingering fears about potential long-term health impacts from the exposure to a mixture of burning chemicals.

The notice the Inspector General quietly posted Tuesday about the investigation said the watchdog will look “to determine whether the EPA and its contractors followed ASPECT flight equipment deployment procedures during the East Palestine, Ohio train derailment" in the hope of improving the response to future emergencies.

Robert Kroutil said he is not sure why the ASPECT plane wasn't
