The refineries are operating at <90% capacity...why do you think they're shutting them down? Do you want to give them government subsidies so they stay open and have a reason to overcompete, just so you can have gas prices lowered, or what?
If you have some concrete examples of what should be changed in the regulations, I'd love to hear them! But regulations (and the governing laws) are put in place for a supposed reason, and unless we demonstrate that reason is satisfied or obsolete, it's very difficult to justify the change.
