SO, is Patoka, IL a refinery, tank-farm or an interconnect hub?
If a hub, where does the crude go from there (along existing lines)?

Fairly significant interconnect point. I’m sure there are multiple regional tank-farms due to that.

Refineries connected by pipeline East, West and to farther away locations.
