The U.S. Environmental Protection Agency doubled initial estimates in its latest update. Meanwhile, Sunoco Logistics reports that its pipeline has been repaired and oil flow has resumed.

Sunoco shut off a stretch of the Mid-Valley Pipeline from northern Kentucky to Lima, Ohio, early March 18 after a leak was confirmed. A company spokesman says the cause of a 5-inch pipeline crack is still being investigated.

The oil leaked into an intermittent stream and acre-sized marshy area in the Oak Glen Nature Preserve just west of Cincinnati.

Officials say no problems have been found with air quality or local water wells, but some small wildlife has been affected.
