Audit finds problems in pipe oversight after deadly blast

Five years after a deadly natural-gas explosion in San Bruno, California’s oversight of utilities’ gas pipelines still suffers from a lack of focus on safety by top state regulators, a new audit says.

The audit finds widespread breakdowns in performance by state-appointed utilities commissioners and by the California Public Utilities Commission since a fiery pipeline breach killed eight people in San Bruno and heightened scrutiny of state regulation of California’s 100,000 miles of natural-gas lines.

The new state-commissioned audit, completed in February and released last month, faulted management at the commission, including the commission’s five state-appointed board members.

In the years since the blast, “frequent management changes, shifting priorities and reactive responses to internal and external recommendations … led to a loss of focus, lack of clear direction, loss of trust in leadership, and unacceptable work backlogs,” auditors said.

The audit, prepared by the Crowe-Horwath consulting firm for the commission, cited other failings, including a fivefold increase since 2010 in the time it took inspectors to prepare safety inspection reports for gas utilities. California regulators are now averaging eight months to process inspection reports, compared with a standard in other states of 15 to 60 days, auditors said.

A National Transportation Safety Board investigation soon after the San Bruno explosion faulted both safety failings by PG&E and lax oversight by the CPUC.

Commission spokeswoman Terrie Prosper said Monday that utility regulators since the end of last year have redesigned their inspection process to give inspectors more time out in the field and speed up inspection reports. Other changes include clearing a backlog of 382 inspection and incident reports, Prosper said.

The CPUC issued a state-record $1.6 billion penalty against PG&E last week in the San Bruno blast. PG&E has said it won’t appeal.

Federal prosecutors also have notified PG&E they are investigating possible corruption in dealings between the commission and the utility.
