I noticed in another thread the mention of nashville being supplied by BARGES up the tenn river perhaps?
This is the case from time to time (also true in the Saint Louis metro, etc). That fact is not really germane to the current problem.
It's not that the pipelines aren't functional, with minor complaints. They're okay. Waiting for something in them.
It's that there's insufficient gasoline/distillates going in the other end. Switching to trucks, railcars, barges, or bike messengers, isn't going to fix that.
Now, if we start getting massive finished product shipments from Europe (or wherever), import of that may be impacted by local issues around the Houston Ship Channel. Then, we may have to look into alternative temporary shipping routes.
With an actual supply disruption, solving a localized outage is just going to be whack-a-mole unless there is major pressure for widespread demand destruction.
