That's something we've been trying to figure out for quite some time.
When she first came into power, we sat down with the governor and tried to brief her on what we were doing with the tunnel, on the operational reliability of the existing pipeline and on the incremental safety measures that we put in place to make sure the pipeline could remain safe while we went ahead and built the tunnel. We talked to her about how we have radar to track all the vessels that go over the pipeline and the straits, and how we hail every vessel that travels through the straits to make sure their anchors are pulled up so there is no inadvertent damage to the pipeline.
We've now put our own vessels on the water to make sure the incoming vessels abide by our safety protocols. We have cameras and other sophisticated equipment looking at the pipeline 24-7 to ensure we are absolutely safe. The pipeline can run at 600 pounds of pressure, but we run it at 150 pounds of pressure. The pipeline's walls are almost an inch thick, which is three or four times the regular wall thickness of pipelines that we run.
This is the most scrutinized piece of pipe in North America. It has the highest safety standards of any pipe in North America. It's the pipeline most reviewed by federal safety regulators in North America. We are abjectly confident that the pipeline is safe.
We're as perplexed as anyone with regard to the governor's motivations. Michiganders themselves support the tunnel. I think our latest polling shows that two-thirds of Michiganders support the Great Lakes tunnel.
