I was curious, too, and even more so because today I saw this outside my house – a fleet of PG&E trucks, complete with a porta-potty. I counted four large trucks, and an earth mover.
There was even a truck blocking one of our garages. When we came out, the PG&E guy running the project offered to moved it if we wanted. As it happened, we didn’t need that garage today, so we said not to bother.
I asked one of the PG&E men what it was about. They’d done a survey some time back, he said, checking for leaks. They were now fixing the ones where they’d detected a problem. He said they had already completed a couple of jobs.
After the terrible accident in San Bruno, I’m glad they’re being proactive here.
