LAUREL, Mont. (AP) -- Exxon Mobil says it will do "whatever is necessary" to clean up its oil spill on the Yellowstone River, while confirming it will be a bigger job than first implied.
The company had said damage would be limited to a 10-mile stretch of the Yellowstone in Montana, where some 42,000 gallons leaked from a 12-inch pipeline under the river beginning Friday night. But Exxon Mobil now says that was misunderstood, and that it was not trying to suggest "in any way" that that's the limit of exposure.
Federal and state officials say damage is spread over dozens of miles. The Environmental Protection Agency says it's still taking air and water samples to determine the impacts.
