An Enbridge company representative has reported that the breach in the Enbridge pipeline that spilled crude oil into the Kalamazoo River was less than five feet (1.5 metres) long. Crews have extracted a 50 foot section of pipe that includes the torn section and sent it off to Washington for analysis by the National Transportation Safety Board. A replacement section is being welded into place, but it is not known when the pipeline will resume operation. U.S. authorities must approval a restart plan and will likely require that the pipeline be operated at reduced pressures. The U.S. EPA is investigating whether Enbridge was negligent in the period leading up to the spill on July 26th.
