On June 3, 2016, a Union Pacific train with 96 tank cars carrying Bakken oil from New Town, North Dakota to U.S. Oil and Refining in Tacoma, Washington derailed in the Columbia River Gorge near Mosier, Oregon. 16 of the 96 cars derailed after the train's emergency brake system about 18 cars back from the engines engaged - several cars then caught fire. By 5pm large explosions were coming from the tankers. All of the tank cars were modern CPC-1232 design.
Washington Department of Ecology, US Coast Guard, Federal Railroad Administration, and Portland Airport's specialty airport fire tender carrying 1,300 U.S. gallons (4,900 L) of firefighting foam were among the 20 agencies that responded. As of 4:30pm firefighters were allowing the fire to burn the oil, simply monitoring it.
Mosier residents were evacuated and the sewage treatment plant was shut down. An oil sheen was seen on the Columbia River by the following morning. Two days after the crash residents were allowed to return to their homes, and freight trains were running on the tracks, to the strong objection of the community. The community then passed an emergency motion asking Union Pacific to remove all oil from the damaged cars before resuming use of the tracks. Union Pacific pushed the damaged cars out of the way and limited the train speed to 10 miles per hour (16 km/h) in the section.
42,000 US gallons (160,000 l) of oil were spilled. Much of it was consumed by fire, some went into the Columbia River, and 10,000 US gallons (38,000 l) were recovered from the city's sewage treatment plant.
The National Transportation Safety Board declined to investigate due to the lack of injuries or fatalities and early information gathered after the incident occurred did not the incident involved no injuries or fatalities and early information gathered indicated that the circumstances of this accident did not pose a significant safety issue.
In response to the derailment and lack of investigation by the National Transportation Safety Board, Oregon Senators Jeff Merkley and Ron Wyden introduced the Mandate Oil Spill Inspections and Emergency Rules (Mosier) Act which calls for a moratorium on oil train traffic after major wrecks and require the Department of Transportation to reduce the amount of volatile gases in the crude oil those trains have been hauling. The bill would die in committee.
