CINCINNATI (AP) -- Officials say a 4-inch pipeline crack caused more than 10,000 gallons of crude oil to leak into a southwestern Ohio nature preserve.
Sunoco Logistics Partners is the primary owner of the pipeline that leaked at the Oak Glen Nature Preserve west of Cincinnati. Company spokesman Jeff Shields said Thursday the U.S. Department of Transportation and others are investigating the cause of the crack.
Crews continue cleaning up the mess from the leak discovered Monday. Officials say about 3,800 gallons of oil and water have been recovered from the leak in a wooded ravine, wetlands, an intermittent stream and a marshy area.
The pipeline is part of Mid-Valley Pipeline Co.'s system running nearly 1,000 miles from Texas to Michigan.
