"Gov. Gretchen Whitmer and Attorney General Dana Nessel, Democrats who campaigned on promises to close the 69-year-old pipeline, began to negotiate with Enbridge on a shorter timeline when they took office in 2019. But the company said it couldn't meet the governor's two-year timeline. "

This was a mistake IMO.  They should have  made every effort to meet this timeline and then paid any penalties for non-completion as they completed it.  It may have been cheaper.

The good news is nobody is questioning the need for Line 5 anymore and a shutdown is unthinkable.
