BILLINGS, Mont. — Attorneys general for North Dakota and Montana asked the Trump administration on Wednesday to overrule a Washington law that imposed new restrictions on oil trains from the Northern Plains to guard against explosive derailments.
In a legal petition to the U.S. Department of Transportation, Montana Attorney General Tim Fox and North Dakota’s Wayne Stenehjem said federal authority over railroads pre-empts the state law.
Washington Gov. Jay Inslee, a Democrat, in May signed the measure that requires oil shipped by rail through the state to have more volatile gases removed to reduce the risk of explosive and potentially deadly derailments.
The move followed a string of fiery and explosive oil train derailments over the past decade, including a 2013 accident in Lac-Megantic, Quebec, that killed 47 people. The explosions drew widespread public attention to the volatile nature of Bakken crude shipments.
But opponents say the new restrictions would make Pacific Northwest refineries effectively off-limits to crude from the Bakken region, one of the nation’s most productive oil fields straddling the North Dakota-Montana border. That’s because the process of treating the oil to make it less volatile would be too expensive to justify, they said.
“It’s pretty clear in this the state of Washington overstepped its bounds,” Fox said. “The effect would be terrible, both on the economies of North Dakota and Montana and also how it offends the rule of law.”
Fox and Stenehjem also warned that allowing Washington’s law to stand could inadvertently undermine safety, by subjecting the railroad industry to a hodge-podge of state laws instead of a common federal standard.
Shipping the region’s crude by rail has become common practice due to a limited number of pipelines, which are considered a safer way to ship oil.
In the first quarter of 2019, almost 16 million barrels of crude moved through Washington, almost all of it from North Dakota, according to a recent report from the Washington Department of Ecology.
Inslee communications director Jaime Smith said the state will defend its law.
“As Washington has experienced an enormous spike in the numbers of oil trains traveling through our state, this legislation is a reasonable approach to anticipated increased volumes of volatile crude oil,” Smith said.
Department of Transportation officials have 180 days to issue a decision on the petition or explain why it’s been delayed and set a new deadline, the agency said in a statement.
