ExxonMobil has agreed to pay a $1.4 million (£0.8m) fine following an oil spill in the US two years ago.
The penalty is for an alleged violation of the Clean Water Act stemming from the spill of at least 2,800 barrels from the North Line near Torbert, Louisiana, the US Department of Justice and the Environment Protection Agency (EPA) said.
The spill was said to have leaked into the Yellowstone River after a pipeline ruptured in April 2012.
The Clean Water Act makes it unlawful to discharge oil or hazardous substances “into navigable waters of the US or adjoining shorelines in quantities that may be harmful to the environment or public health”.
Sam Hirsch, Acting Assistant Attorney General for the Justice Department’s Environment and Natural Resources Division said: “Oil spills into our nation’s waters endanger public health and the environment and warrant concerted enforcement efforts.”
