| The tanks are just across the street from a major Enbridge 
				Inc crude oil facility. That facility did not appear to have 
				been damaged, despite initial concerns it had been affected.
 It was not immediately clear who owns the storage tanks that 
				caught fire and emergency responders declined to comment. The 
				tank battery does not appear on state regulators' maps.
 
 The crude damaged by the blaze is a minute proportion of the 
				more than 1 million barrels produced each day in North Dakota, 
				the second-largest oil-producing state in the United States.
 
 The crude will likely have to burn off completely before the 
				fire dies out, McKenzie County Deputy Sheriff Per Perez said.
 
 The cause of the blaze remained under investigation, officials 
				said, but foul play was not suspected.
 
 The blaze started when two trucks were delivering crude to the 
				12-tank battery on Thursday afternoon, officials said. Nearby 
				residents reported hearing and feeling an explosion.
 
 Each tank has a capacity of 210 barrels. All 12 of the tanks 
				contained crude, Perez said, and eight of them caught fire.
 
 Trucks must be grounded each time they deliver crude, and it was 
				not clear if both of the trucks were properly grounded on 
				Thursday to divert electrical discharge.
 
 Drivers of both trucks got away safely, Perez said.
 
 An Enbridge spokeswoman was not available to comment.
