California lawmakers railed Tuesday on both PG&E Corp. and the agency tasked with monitoring the energy company at a hearing on the San Bruno pipeline explosion.

California Public Utilities Commission leaders were asked why they haven’t more closely monitored PG&E’s expenditures on maintenance and audited the company.
Lawmakers also asked repeatedly why the CPUC has yet to fine PG&E for a pipeline blast that killed a man in
Rancho Cordova.

CPUC Consumer Protection and Safety Director Richard Clark said that the agency doesn’t fine PG&E more frequently because it is trying to foster “a culture of safety.”
