In order to be prepared to serve our community in the wake of a San Francisco oil spill, The Brod Law Firm follows oil-related disasters across the nation. Just last week, federal investigators revealed the results of their inquiry into a 2010 incident in Michigan. For the Northern California region, this report is especially notable because it bears several similarities to the explosion that rocked San Bruno during that same year.
MSNBC is one of several news outlets carrying the Associated Press story about the most expensive onshore oil spill in our country’s history. On July 25, 2010, at approximately 6 P.M., oil began leaking from a 30-inch pipeline in southwestern Michigan. Alarms sounded repeatedly at the control center of Enbridge, Inc., the line’s Canadian operator, but staffers misinterpreted the warning. Overall, the ruptured pipeline dumped approximately 843,000 gallons of heavy crude into the waters of the Kalamazoo River and a tributary creek. About 320 people reported health symptoms that officials tied to oil exposure and the spilled crude fouled over 35 miles of waterways and wetlands. Cleanup costs have surpassed the $800 million marks, more than five times more than the second-costliest onshore spill in U.S. history.
According to the National Transportation Safety Board (“NTSB”), Enbridge failed to respond appropriately to the Michigan catastrophe and also neglected to adequately address structural problems that had been detected years prior. By 2005, five years before the spill, the company knew that the pipeline, located about 95 miles west of Detroit, was cracked and corroded. According to the report, Enbridge did not grasp the significance of the developing cracks and did not appropriately investigate other findings about pipe wall thickness. Enbridge did not perform excavations and visual inspections, actions that NTSB investigators believe could have prevented the rupture. Investigators believe that trapped moisture caused corrosion on the pipeline, leading to cracks that eventually linked together to cause the rupture.
