As for oil train safety problems, in one of her last acts before leaving office last week, outgoing National Transportation Safety Board Chairman Deborah Hersman warned the Obama administration that it needs to take steps immediately to protect the public from potentially catastrophic accidents even if it means using emergency authority.
The safety board has long recommended that the Department of Transportation toughen its design standard for the kind of rail tank cars used to transport crude oil and ethanol. The cars are too easily punctured or ruptured, even in low-speed accidents. Their flammable contents are then spilled, fouling the environment and often igniting.
"We are very clear that this issue needs to be acted on very quickly," Hersman told reporters at the conclusion of a two-day forum the board held on the safety of rail transport of oil and ethanol.
In 2011, the oil, ethanol and railroad industries agreed to toughen standards for rail cars known as DOT-111s, which are the kind of tank cars used to transport most flammable liquids. However, since then, there have been several accidents in which cars built to the new standards ruptured. NTSB officials have said the voluntary standards don't go far enough.
It's most likely the tank cars involved in the Lynchburg accident were older DOT-111s or new "enhanced" DOT-111s because that is what is primarily being used to transport crude oil, said Bob Chipkevich, a former head of NTSB rail accidents investigations.
