Facing SouthExxon's Yellowstone Oil Spill Shows Pipeline Risksby Sue Sturgis
The environmental disaster that began unfolding last week when an ExxonMobil pipeline ruptured in Montana and spilled an estimated 42,000 gallons of oil into the Yellowstone River highlights the serious environmental risks associated with the oil industry's infrastructure -- and foreshadows the problems likely to arise if that infrastructure spreads to other states that are now considering offshore drilling.
The Houston-based oil giant reports that more than 280 personnel are now involved in cleaning up the spilled oil, which has contaminated farms and other properties along the scenic waterway.
The spill occurred when Exxon's Silvertip pipeline buried six feet below the river sprung a leak last Friday. Though the cause of the leak is not yet known, Eastern Montana got record rainfall last month, and some local officials have raised the possibility that the surging water exposed the pipeline, which in turn could have been damaged by debris.
But there have been problems along the Silvertip before. The U.S. Department of Transportation, which oversees oil pipelines, notified Exxon last July of seven potential safety violations on the Silvertip, with two of the warnings citing problems with the company's emergency response and pipeline corrosion training, CBS News reports. In May, the Silvertip was shut down due to concerns over rising waters, but Exxon restarted the line a day later after deciding the risk was low. ............(more)
