It's a hypothetical, and one that I'm very confident won't arise, but it is worth exploring that, just so we all understand what's at stake. People aren't going to go cold. It just means that the energy, those molecules, are going to have to be transported by rail, by truck or by marine transportation. But they will have to get to source, because people will not be kept cold, that's for sure.
I draw attention to the editorial that was written last week in The Detroit News and seemed to be singularly directed to Governor Whitmer. It said that one of the reasons why Michiganders remained warm when in so many other bordering states people went cold, particularly farther down south in Texas, was because of Line 5.
Line 5 supplies 65% of the propane needs of Michigan's upper peninsula, 55% of the statewide propane needs and 28% of the feedstock for production for jet fuel at the Detroit airport. This is significant for them and for refineries in Michigan, in Ohio, in Pennsylvania—all dependent on that line for their continued operations. Two refineries in Toledo, Ohio, are at risk of shutting down if Line 5 shuts down. You're talking thousands of direct and contracted skilled trade jobs at risk and $5.4 billion in annual economic output.
A shutdown of Line 5 would cause an over 14 million gallons a day supply shortage in the region. Michigan alone would face an over 750,000 gallons a day propane shortage. That's significant.
