“Learning about Enbridge’s poor handling of the rupture, you can’t help but think of the Keystone Kops,” said Deborah Hersman, chair of the NTSB. “Why didn’t they recognize what was happening? What took so long?” she said in a statement. She said that despite alarms and pressure differentials, Enbridge staff twice pumped more oil, about 81 per cent of the total release, into the ruptured pipeline. Hersman said that oil gushed from the rupture for more than 17 hours before the leak was discovered.
