SAN FRANCISCO — Pacific Gas & Electric was charged Tuesday with lying to regulators in connection with a fatal pipeline explosion that killed eight people and leveled a suburban Northern California neighborhood in 2010.
The U.S. attorney in San Francisco announced the obstruction of justice charge and 27 related counts, which are in a new indictment charging the utility with felonies. It replaces a previous indictment that contained 12 counts related to PG&E’s safety practices, but not obstruction.
Prosecutors say PG&E hampered the investigation by lying to regulators soon after the blast. In particular, PG&E officials are accused of telling National Transportation Safety Board investigators that the safety procedures being followed were correct and approved.
The other charges accuse the utility of failing to act on threats in its pipeline system even after the problems were identified by its own inspectors. The indictment charges PG&E with keeping shoddy records, failing to identify safety threats and failing to act when threats were found.
Investigators found that PG&E had inaccurate records on its more than 6,000 miles of gas transmission lines, and that as a result hadn’t tested for the defective seam weld that ruptured a pipeline and ignited a fireball.
No employees or executives have been charged in the San Bruno disaster. Prosecutors could still file another indictment charging individuals.
The utility announced in June that it was expecting the new indictment. PG&E spokesman Greg Snapper said company officials had not yet seen it.
“However, based on all of the evidence we have seen to date, we do not believe that the charges are warranted and that, even where mistakes were made, employees were acting in good faith to provide customers with safe and reliable energy,” he said in a prepared statement.
The new charges expose PG&E to more than $1 billion in fines. It had preciously faced up to a $6 million fine under the old indictment.
In addition, the utility is facing lawsuits and $2.5 billion in civil fines from regulators, including the state Public Utilities Commission. San Bruno city officials on Monday demanded the head of the PUC resign, alleging the agency had improper contacts with PG&E.
Besides killing eight people, the explosion injured dozens and destroyed 38 homes. Nearly four years later, the neighborhood about 12 miles south of San Francisco is still recovering.
On Tuesday, San Bruno City Manager Jim Ruane said “the new criminal charges demonstrate a pattern of deceit by PG&E.”
PG&E said in May that it has committed $2.7 billion over the next several years for safety-related work following the incident.
Its profits were weighed down in its most recent quarter by $40 million in legal and safety improvement costs tied to its natural gas business.
