July 4, 2011 at 12:00 AM EDT

HARI SREENIVASAN: A major cleanup effort was under way today in Montana, after an oil spill spewed up to 42,000 gallons into the Yellowstone River. The ExxonMobil pipeline ruptured late Friday near the town of Laurel. Since then, the oil has traveled about 100 miles east, near Hysham.

The oily residue has washed up on the riverbanks, but is still downstream from Yellowstone National Park. Crews are laying sheets of absorbent padding and booms to prevent further damage.

The president of ExxonMobil said an investigation is under way.

GARY PRUESSING, ExxonMobil: We do not know the root cause. This is a very unusual event. Obviously, we had a large amount of oil enter the water very quickly. So, whatever it is, it’s something that is very unusual for us, something that we do not have our hands around yet. But the investigating team certainly will work hard to determine that.

HARI SREENIVASAN: The U.S. Department of Transportation, which oversees pipelines, recently notified ExxonMobil of seven potential safety violations along the ruptured pipe. Two of the warnings faulted the company for its emergency response and pipeline corrosion training.
