At approximately 11:00 PM on Friday, July 1 a break occurred in a 12-inch pipeline owned by ExxonMobil that resulted in a spill of crude oil into the Yellowstone River approximately 20 miles upstream of Billings, Montana. According to the company’s estimates, 1,000 barrels (42,000 gallons) of oil entered the river, which is in flood stage, before the pipeline was cut off.
