Shippers in North America use about 66,000 of the so-called legacy tank cars to haul flammable liquids, including about 23,000 that carry crude, according to industry representatives.
The Obama administration has said it will propose a new rule this month governing tank cars that could include retrofits of older cars and tougher standards for new ones.
However, that “will take too long to address the imminent hazard posed by use of dangerous DOT-111 tank cars to ship crude oil,” according to the petition filed by the law firm Earthjustice on behalf of the two environmental groups.
