The leak occurred on Tuesday morning on a four-mile pipeline which runs from the Long Beach Terminal where oil tankers dock to the East Hynes Terminal in a heavily industrialized part of Long Beach, said BP spokesman Scott Dean. No oil went into waterways and most was retained by a concrete casing around the pipeline, Dean said. BP had by Friday afternoon cleaned up 60 barrels, he added.
Much of the pipeline is buried underground.
Local, state and federal officials are investigating the cause of the leak and monitoring its cleanup, Dean said.
No one was injured because of the leak, he added.
