Hundreds of rail cars filled with North Dakota crude oil pass through Minnesota each day. That reality has state and federal leaders worried about safety.
Some — including Gov. Mark Dayton — argue oil companies should take steps to reduce the oil's volatility before loading it onto train cars. Proponents say that would minimize the chance for explosions if a train were to derail or crash. Dayton sent a letter to North Dakota's governor this week calling for stricter standards on the quality of oil shipped by rail.
But industry reps say that simply isn't necessary — that their oil is safe to ship.
MPR's Cathy Wurzer spoke with Chester Dawson, a senior correspondent at the Wall Street Journal, who has been covering this issue from North Dakota.
