A North Carolina state agency says it's filed a lawsuit seeking to force Colonial Pipeline to meet obligations resulting from a gasoline spill that was found to be far worse than the company initially reported. In a news release, the North Carolina Department of Environmental Quality says it filed the 29-page lawsuit in Mecklenburg County Superior Court on Monday to force Colonial “to meet their obligations as the responsible party in the state’s largest gasoline spill.” Originally reported as a 273,000-gallon spill, Colonial Pipeline later disclosed the spill involved more than 1 million gallons.
