Safety Board Issues Urgent Call for California Utility to Test Gas Pipelines

The National Transportation Safety Board has issued a series of urgent recommendations in response to the fatal explosion of a California gas pipeline in September.

The recommendations call for more scrutiny of Pacific Gas & Electric Co., the utility whose gas line exploded, killing eight people in San Bruno, Calif. The NTSB urged PG&E to identify pipelines that haven’t been subjected to testing for safe operating pressures and to perform the necessary examinations. The agency also called upon state regulators to ensure that the company fulfills its testing obligations.

The agency classified six of its seven recommendations as urgent, a rare designation used only in the most serious investigations.

The NTSB also addressed PG&E’s record-keeping, which had wrongly described the line that exploded as made of seamless pipe. Such errors could lead unwitting operators to allow high pressure levels in pipelines unable to sustain them, increasing the risk of dangerous ruptures.

“We’re very concerned about making sure operators nationwide know what kind of pipe is on their lines,” NTSB Chairwoman Deborah Hersman told the Associated Press. “This was a tragic accident and we wanted to make sure we got this information out urgently.”

A PG&E spokesman said the company is reviewing its record-keeping procedures, and is working closely with the NTSB to ensure compliance.
