Enbridge was forced to shut down one of its pipelines last week after 900 barrels of crude oil leaked at the Mokena tank farm near Chicago. The leak was discovered on Tuesday of last week although its cause remained undisclosed until this morning, when the Mokena fire department cited a hole in a 20-inch pipeline. 

The leak forced the shutdown of Enbridge's Line 14, a pipeline carrying 318,000 barrels of oil per day from Superior, Wisconsin to Mokena, Illinois.
