The chair of the National Transportation Safety Board on Tuesday condemned Norfolk Southern for interfering with its investigation into last year's East Palestine train crash and the "vent and burn" of harmful chemicals that followed.
The remarks came at the final NTSB hearing on the disaster, in which the agency released a preliminary report—damning to Norfolk Southern and its contractors—from a 17-month investigation. NTSB officials explained that a decision to intentionally burn vinyl chloride, a carcinogen, from five derailed train cars was flawed and resulted from the company's selective sharing of information with officials at the time.
Norfolk Southern's uncooperative approach didn't stop after the vent-and-burn, according to the NTSB. Throughout the investigation, the company delayed or avoided sharing information, sought to "manufacture" evidence, and even issued a "threat" to agency staff, Jennifer Homendy, the NTSB chair, said.
