File - In this Sept. 9, 2010 file photo, a massive fire roars through a mostly residential neighborhood in San Bruno, Calif. The California agency investigating a deadly pipeline explosion and the City of San Bruno are set to propose major fines they say Pacific Gas & Electric Co. should pay for its negligence leading up to the blast. The City of San Bruno says the utility's shareholders should pay no less than $1.25 billion for violations regulators say PG&E committed before the 2010 explosion. (AP Photo/Paul Sakuma, File) less
