SAN FRANCISCO — The California Public Utilities Commission voted on Thursday to impose a $14.35 million fine on Pacific Gas & Electric Co. for filing faulty records related to a natural gas pipeline and waiting too long to correct them.

“There should be no question that the CPUC expects nothing less than forthright and timely disclosure in all matters of public safety,” said Commissioner Mark Ferron, who authored the decision. “This fine sends a strong signal to PG&E, and to all of the utilities that we regulate, that delay and obfuscation will not be tolerated.”
