San Bruno Blast Probe Reveals Shoddy Record-Keeping, Official Says

The National Transportation Safety Board appears likely to come down hard on Pacific Gas & Electric in its final report on the pipeline explosion and fire in September that killed eight people and destroyed 38 homes in San Bruno, Calif.

A strong signal of where the NTSB is headed came on Wednesday, in a Washington speech by the agency’s chairwoman, Deborah Hersman. She lambasted the utility company for shoddy record-keeping that led to safety hazards, the San Francisco Chronicle reports.

“In the years since the pipe was put into service, decisions regarding inspections, operating pressures and risk management plans were all based on facts that were just plain wrong,” Hersman told the  National Research Council’s Transportation Research Board, a gathering of thousands of policymakers, researchers and industry officials.

“Our investigators were told that the pipe involved in the explosion was a seamless, factory-manufactured pipe,” Hersman said. “But even a layperson could see the patchwork of welds marking the pipe.”

The NTSB said last week that the rupture in that pipeline was caused by a poorly welded longitudinal seam. PG&E “has not been able to produce documentation on the origins of the pipe, the installation of the pipe, or the early inspection of the pipe,” Hersman said. “But no one realized this until after the pipeline exploded. And then it was just too late.”

Hersman cited the San Bruno disaster as an example of why the pipeline industry should reevaluate its safety systems.

A PG&E spokesman said the utility is “concerned about the issue with our records” and has been “undertaking an intensive review” of the company’s data.
