MARSHALL, Mich. - More repairs will be required as part of a deal that will permit Enbridge Energy Partners LP to restart Line 6B, which ruptured and spilled an estimated 19,500 barrels of Canadian synbit (upgraded bitumen) into Michigan’s Kalamazoo River watershed in July.
The Office of Pipeline Safety of the Pipeline and Hazardous Materials Safety Administration notified Enbridge on Sept. 22 that its was approving the latest restart plan for the pipeline, which runs from Griffith, Ind., to Sarnia, Ontario.
Federal regulators said in a letter to the company that they want dozens of pipeline anomalies fixed within 180 days of a restart. A dented pipeline that runs beneath the St. Clair River would have to be replaced within one year of a restart.
Democratic U.S. Rep. Mark Schauer of Michigan released the letter of approval on Sept. 20, before the letter was received by Enbridge.
More about the restart and fixes in future articles.
