LA TimesCalifornia utility regulators are taking an increasingly tough stance toward Pacific Gas & Electric Co. one week after a gas pipeline explosion and fire killed at least four people and destroyed or damaged dozens of homes in the San Francisco suburb of San Bruno.
Late Friday, the executive director of the California Public Utilities Commission wrote PG&E President Christopher Johns asking for specific detailed information about potential weak links in its 5,700-mile natural gas transmission network.
Foremost on the PUC’s list of seven demands is a request for PG&E’s list of its top 100 high-priority pipeline projects. The San Francisco-based, for-profit company repeatedly refers to the list in documents filed with the PUC but has not provided the agency or journalists with the actual document.

Such devices can be closed in less than 10 minutes, experts say. It took PG&E workers more than two hours to close the manual valves on either side of the San Pedro rupture, leaving gas in the line that fed an out-of-control fire.
