Noel Griese of Energy Pipeline News has a report on statements made on August 4 by Representative Mark Schauer (Dem.) of Michigan about the recent Enbridge oil spill into the Kalamazoo River. The National Transportation Safety Board thinks the rupture occurred around 6 p.m. on July 25, when the pipeline was shut down for maintenance. Schauer says that Enbridge restarted the pipeline at 4:26 a.m. on July 26 and repeatedly turned it on and off for the next several hours because of spikes in readings, Schauer said. Each time the line was restarted, more oil would spew from the five-foot-long rupture or “smile” in the compromised pipeline. That would explain the exceptionally large volume spilled.
