Could be something going on.
After Katrina, I proposed to one oil company to put a 60 foot to 90 foot dirt wall around the refinery to protect against terrorism and storm surge.
It would also contain any explosion within the dirt wall.
The one refinery fire in California was due to a vapor cloud coming contact with a spark from an engine that was idling (fire truck, of all things).
That was the Chevron-Richmond fire. I had not heard of a second refinery fire in California/West Coast.
This attack at a refinery.
Not sure a refinery is the target. This occurred in a parking facility where workers park and shuttle service is used to get them to mulitple work facilities in the area.

The shooting occurred around 5:30 a.m. in a parking lot used by workers in an area of manufacturing plants and refineries along the Mississippi River........
Settle down! There has been refinery fires in California for decades.
