Exxon Mobil Corp. will pay $1.05 million to settle federal violations for polluting the Yellowstone River in Montana in 2011, when a broken pipeline dumped 63,000 gallons of crude oil 150 miles downstream from Yellowstone National Park.
Last month’s 210,000-gallon oil spill from the Keystone pipeline in South Dakota may have resulted from damage caused during construction, according to a preliminary investigation by the U.S. Dept. of Transportation’s Pipeline and Hazardous Materials Safety Administration.
Work is underway to clean up the “inadvertent return” of an estimated 2 million gallons of bentonite-based drilling fluid into high-quality wetland that occurred during horizontal directional drilling under the Tuscarawas River in Stark County, Ohio, for Energy Transfer Partners L.P.’s Rover Pipeline.
