Looks like I should fill up all the cars with gas this morning.

Chevron Richmond refinery hydrocracker explosion causes warning for all residents to stay indoors.

California has their own special rules for gas, meaning that refineries have a unique recipe that they have to follow to make fuel that can only be used in this state. A shutdown of a refinery this size can only mean higher gas prices, perhaps much higher.  It will be an education to see just how much effect this has at the pump.
