Cracks and Corrosion

The accident was triggered by a six-and-a-half-foot tear in Line 6B, a 30-inch carbon steel pipeline. Enbridge knew about corrosion and cracks in the pipeline for at least five years before the spill, the National Transportation Safety Board (NTSB) concluded in an accident report issued on July 10.

After the spill, an internal investigation by Enbridge Inc. and Enbridge Energy Partners led to changes in processes and training, including at its control center, according to a July 10 press release issued in response to the NTSB's findings. "We believe that the experienced personnel involved in the decisions made at the time of the release were trying to do the right thing," Patrick Daniel, Enbridge Inc.'s chief executive officer, said in the release. "As with most such incidents, a series of unfortunate events and circumstances resulted in an outcome no one wanted."
