BISMARCK, N.D. (AP) — The derailment in West Virginia of a train carrying oil from North Dakota is prompting complaints that North Dakota and federal government leaders aren't doing enough to ensure the safe transport of crude by rail.

A train carrying 3 million gallons of crude derailed Monday in the unincorporated town of Mount Carbon, West Virginia. The derailment leaked oil into a river tributary, burned down a house and forced nearby water treatment plans to temporarily shut down.

Consumer advocate Ralph Nader tells KFGO radio he's calling for a congressional investigation into rail accidents involving North Dakota crude. He calls it "a national emergency."

The Dakota Resource Council environmental group tells The Bismarck Tribune that state officials are to blame for not ensuring oil is safe to ship. State leaders dispute that.
