An oil spill in Montana's Yellowstone River surged toward North Dakota on Sunday as outraged residents demanded more government oversight of Exxon Mobil's cleanup.
An estimated 750 to 1,000 barrels, or up to 42,000 gallons, spilled overnight Friday through a damaged pipeline in the riverbed, Exxon spokesman Alan Jeffers said. The break near Billings could be related to the river's high water level, officials said.
More than 100 people were working on the cleanup late Sunday, Jeffers said. But local officials said because of the raging floodwaters, only a handful of crews were laying absorbent pads and booms to trap the oil along short stretches of the river between Billings and Laurel. In some areas, residents said, oil may be flowing underneath the booms and continuing downstream in the murky water.
