Given that a great deal of the risk is directly cause by maintenance that PG&E has chosen to defer for years... how is it not under their control? I can accept that perhaps some other parties should share some of the liability, but it seems completely unsupportable to claim that PG&E has no control over these risks and should be absolved of all responsibility.
