WASHINGTON, July 10 (UPI) -- A 2010 pipeline rupture that dumped nearly a million gallons of oil into a Michigan waterway was blamed on operator negligence at a government hearing Tuesday.
At the opening session of a hearing on the spill, National Transportation Safety Board head Deborah A.P. Hersman said Enbridge Energy Partners of Houston and operators of the pipeline detected the defect that led to the 2005 accident and failed to fix it, the Detroit Free press reported Tuesday.
