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.
Enbridge spokesman Graham White told the Chicago Tribune Friday that the spilled 37,000 gallons of crude were “contained within the tank berm,” causing little environmental impact. The U.S. Pipeline and Hazardous Materials Safety Administration (PHMSA) is investigating the accident.
The Mokena spill is yet another incident in a long list of Enbridge operational failures that have severely weakened the company's public standing and professional reputation.
