BNSF railroad is regularly hauling three trains a week loaded with crude oil through the Sioux Falls area, but those are the only shipments of crude oil from North Dakota's Bakken region crossing the state.
The South Dakota Department of Environment and Natural Resources posted records online Wednesday with details of crude oil shipments. The Associated Press had requested those records.
This spring railroads were ordered to notify states about trains carrying at least 1 million gallons of crude oil.
BNSF says it is hauling three trains a week with more than 1 million gallons of crude oil apiece through Minnehaha County. The railroad has also disclosed that three trains a week pass through four northwest Iowa counties.
Canadian Pacific says it isn't carrying crude oil through South Dakota.
