It was one of the worst disasters of its kind, killing eight people and destroying dozens of homes. And it's prompted several bills from state lawmakers. Democratic Assemblyman Jerry Hill's district includes San Bruno.
Hill: "As we look back, we wonder, could it happen again? I tell you today, and with my wonderful colleagues behind me, it's not going to happen on our watch."
Hill's bill would require the installation of automatic or remote shutoff valves on pipelines. That's in response to PG&E taking more than an hour after the explosion to turn off the gas to the faulty pipeline. Measures also deal with other safety requirements and how much money utilities can charge customers.
PG&E says it isn't opposed to any of the bills - and it's already addressing many of their provisions.
Some measures face final votes this week. Others are already on their way to the governor.
