Federal regulators have rejected an initial proposal by Enbridge Energy Partners to restart a pipeline that leaked oil into the Kalamazoo River in southern Michigan.
The Pipeline and Hazardous Materials Safety Administration says Tuesday it wants more safeguards in the restart plan. That includes investigation and possibly repair of other anomalies in the pipeline that runs from Griffith, Ind., to Sarnia, Ontario.
Enbridge will have to revise its restart plan and it isn’t known when pipeline service might be restored.
An estimated 820,000 to more than 1 million gallons escaped from the pipeline near Marshall in a leak reported July 26.
Enbridge and the Environmental Protection Agency say that cleanup is progressing well.
