PG&E probably has the best watt/btu delivered safety record in the USA. I work about 10 miles from the port of Catoosa, it's the furthest inland navigable port in the USA. Their is a nitrogen fertilizer plant and it uses nat gas as a raw ingredient, and lots of it. The port and ng line was laid during the early 70's. I'm sure the reason they are running a new pipe through my property is a direct result of the PG&E explosion. While talking to the land man, he said soon as the new line was in operation, the pressure would be lowered in the old one for residential use. It's just a shame that it had to happened in a residential area for the industry to care or change. leaks usually happen in the cross country areas, and nothing seems to be done, but fixing the leak. Mexico had a real bad one happen. Around here, some idiots hot tap those cross country line to supply gas for their homes.
