State investigators issued a report Monday blasting Pacific Gas & Electric Co. for keeping disorganized, difficult to access records about its natural gas pipelines in the years preceding the fatal San Bruno explosion.
The findings by the California Public Utilities Commission staff were part of an investigation into whether the record keeping lapses violated state and federal laws and contributed to the pipeline rupture.
In recent months, federal and state reviews have faulted the company's management of its gas lines before the Sept. 9, 2010 blast. Eight people died and 38 homes were destroyed in the San Francisco suburb.
PG&E could face millions of dollars in fines for violating state and federal safety rules.
Also on Monday, San Bruno city officials announced that a $70 million settlement had been reached with PG&E for restitution for the deadly explosion. The settlement came after months of negotiations between the city and utility over what compensation is necessary.
