The current Enbridge Line 3 tar sands pipeline is more that 50 year’s old. It’s badly corroded and only runs at only 50 percent capacity to reduce spill risks.
Monitoring tools inside the pipeline identify potential problems. When found, workers dig down to the pipeline, inspect it, and make repairs. This is called an “integrity dig.” Enbridge estimated the current Line 3 would need 4,000 integrity digs over 15 years for its safe operation. That’s a lot of digging.
There’s a lot more integrity problems than just one old pipeline. Our entire regulatory system has integrity problems, including its failure to stop the dangerous and unnecessary Line 3 pipeline.
Collectively, we need to dig into this corroded system, understand how it got so compromised, and fix it.Continue reading
