CHARLESTON - The Coast Guard says it has identified the source of a recent oil spill in a South Carolina harbor.
Officials said Tuesday that a 600-foot cargo vessel caused the spill that left oil sheen and tar balls in the Charleston Harbor and on surrounding beaches last month. Witness accounts and forensic tests were used in the investigation.
The Coast Guard says the vessel reported a 10-gallon oil spill on Oct. 19. The spill happened as heavy bunker fuel was being transferred from a barge to the ship, and the vessel owners hired a local contractor to clean up the oil.
Witnesses say no oil was seen in the water when the contractor arrived. The spill is still under investigation.
