The picture of the Chevron Refinery is plain frightening. My hubby is a ChemE in this industry, spcifically, hazardous clean-up for these types of facilities, and I can actually say everyone should be VERY concerned at that picture.
I don't see any problems in that pic. The water in the flooded tank farms is contained in the retention ponds that are designed to contain any product leak from the tanks. There's no sign whatsoever of leaks. ie.irridescent sheens.
The facility itself was shutdown and prepared for the storm beforehand. That equipment is quite able to handle the storm. Note the tanks are full and appear untouched also.
As far as I know, Chevron has not reported that this refinery has incurred significant damage.
