NTSB calls San Bruno pipeline explosion 'A failure of the entire system'


WASHINGTON - In a scathing critique, federal investigators with the National Transportation Safety Board (NTSB) in an Aug. 30 hearing blamed Pacific Gas & Electric Co. for what one official called "baffling" mistakes that led to a gas pipeline explosion in September 2010 that killed eight people and destroyed 38 homes in the San Francisco Bay Area.

The NTSB also said PG&E exploited the lack of monitoring by regulators, who mistakenly placed "blind trust" in the utility.

The report made on Aug. 30 concluded that poor pipeline welds went undetected because of a lack of inspections by the company and inadequate monitoring by state and federal regulators. The utility also lacked a workable emergency response plan that board members said could have helped to prevent the devastation in the city of San Bruno.

"This represents a failure of the entire system - a system of checks and balances that should have prevented this disaster," said Robert L. Sumwalt, an NTSB board member. "The seam weld may have been the technical reason, but this was an organizational accident."

PG&E says its inaccurate records did not lead to San Bruno blast

SAN BRUNO, Calif. - The gas pipeline explosion that killed eight people and destroyed 38 homes in San Bruno would have happened even if Pacific Gas and Electric Co. had kept accurate records of the line, the company told state regulators on April 19.


The rupture on the 30-inch transmission line that caused the Sept. 9 explosion took place at an incomplete weld on a pipe seam, metallurgists with the National Transportation Safety Board have concluded. PG&E's records showed that the pipe had no seams, and it never conducted inspections that might have detected a flawed seam weld.

However, the type of weld that ruptured does not have a record of failing, PG&E told the state Public Utilities Commission. As a result, it said, the company still would have picked an inspection technique best suited for finding the problem that PG&E considered the greatest threat to the line - corrosion - and not flawed welds.

"The question becomes whether the correct seam type information ... would have changed PG&E's assessment methodology" and "potentially prevented the Sept. 9, 2010, San Bruno pipeline rupture," the company said. "The short answer to that question is 'no.' "

Federal investigators cite defective welds as likely cause of fatal San Bruno blast

SAN FRANCISCO, Calif. - A federal report issued on Jan. 21 says that the natural gas pipe that ruptured in San Bruno on Sept. 9, killing eight people and destroying 38 homes, had numerous flawed welds. According to some experts cited, the pipe did not meet even the welding standards in place when it was installed in 1956.

The metallurgical report shed new light on the blast, identifying for the first time a particular seam weld as the site of the rupture. It found that the weld was half as thick as it should have been.

The problem seam weld in San Bruno, the NTSB report notes, developed a crack "consistent with ductile overstress from the root of the weld." A surge eventually ripped apart the line at the seam at a time when pressure ran up to 386 pounds per square inch. The pressure surged because of a malfunction of the pipeline system's power source before the San Bruno explosion.

The report noted that there were several circumferential, or girth, welds, and all of them had similar flaws. One of them also failed in the accident, but the report did not specify the cause of the "overstress" on those welds.
