Around 407,000 gallons spilled onto farmland when the pipeline broke near Amherst in Marshall County on Nov. 16, a spokeswoman for pipeline owner TransCanada Corp., told the Aberdeen American News. TransCanada had originally put the spill at 210,000 gallons.
The new number would make the spill the seventh-largest onshore oil or petroleum product spill since 2010, as reported to the U.S. Department of Transportation. Repairs have since been made and the cleanup is done.
TransCanada resumed using the pipeline 12 days after the leak.
