Another PG&E pipe ruptures under pressure testing!

I bet you're thinking you've heard about this one because there have been so many failures lately, but unless you heard about one on Monday Nov 7 in which unleashed a landslide onto a Bay Area freeway you'd be wrong.

One reason we are hearing about so. many failures this year is that in earlier years other means were used to determine pipeline integrity.  Those means were shown to be spectacularly inadequate when a pipeline erupted in San Bruno in September 2010.
