>THE REPORT ON THE ENBRIDGE PROPOSAL
Some of the conclusions in Accufact’s scathing report on Enbridge’s proposal for Line 9B, which the company said it looks forward to disputing in public hearings later this month.
Stress corrosion cracks are prevalent and high-risk along Line 9.
Cracks are most likely to fail as ruptures.
Crack detection tools “appear” to still be a “research experiment.”
Changing types of crude in the pipe will speed up crack growth.
Enbridge has failed to heed some recommendations from U.S. regulators in the aftermath of a catastrophic 2010 spill in Michigan.
Something “appears very wrong” with the company’s risk assessment.
Emergency response plans and times aren’t adequate.
Enbridge’s leak detection won’t detect a rupture quickly.
Volumes that would spill in the event of a rupture are “in all probability understated.”
