Chevron Failed to Properly Inspect Pipe That Ruptured, Causing Massive Calif. Fire

Remember the massive fire at a Chevron oil refinery in Richmond, California? Well, it appears that it was caused by ruptured pipe that Chevron failed to inspect and replace, according to its own guidelines.

SF Gate reports that federal officials say there was "no indication that the 8-inch diameter segment was inspected during a November 2011 maintenance shutdown."

Investigators say the section of pipe had lost 80% of its wall thickness, and was just to 1/16th of an inch thick when it failed.

Chevron policy is to replace pipes showing greater than 50% loss of wall thickness.
