As I had stated I work at AAPL until 89, and on the mainline they had MOV valves at all the pump stations, not sure what they had on this branch line? IF I had to guess I would think they'd carry the same philosophy at the M/L pumps stations there also. This pipeline was totally remotely operated, with maintenance people just "visiting" the site as needed or scheduled. I still haven't heard what failed, but I would think if they had a functioning leak detection system then some of the damage could have been avoided, semi steep ravens in that area are pretty common, with limited access.
 
Thanks Steve for that posting. It is extremely revealing. There certainly appear to be some "major inconsistencies" in the company's story now coming to light. I find it very difficult to believe (more like impossible) that an intelligent pig run would not reveal only 1/16" of wall thickness remained, and over such a substantial portion of the pipeline.

Looks like PHMSA is bringing their full weight to bear as well.
 
Classic failure mode with a wrapped thick film coating. The reporter, not being a CP expert, appears to have possibly misconstrued the implications of 'shielding,' i.e. the prevention of CP current reaching the pipe surface.

Amazing when the fine for 1500 bbl release is only 1MM.

Exxon still reportedly owes $92MM for the Valdez fiasco.
Apparently they prefer to pay the lawyers as much of that money as possible.
