Pacific Gas & Electric Co. has revealed that its employees dispute key information the company gave federal investigators about past problems on the gas line that ruptured.
A pipeline that exploded in San Bruno last fall sprang a gas leak in a nearby spot years before, but Pacific Gas & Electric only told federal investigators about it a few weeks ago.
Federal prosecutors were seeking thousands of pages of documents from California regulators as they launched an investigation into the deadly gas pipeline explosion in San Bruno.
The city of Palo Alto has launched a pipeline safety campaign designed to warn residents about the dangers of “cross bores.”
Regulators said Wednesday they plan to fine Pacific Gas & Electric Co. up to $1 million a day to sanction the company for failing to turn over key safety records.
Pacific Gas & Electric said it is missing 8 percent of the records the utility is required to keep to ensure its pipelines are running safely.
State regulators have threatened Pacific Gas and Electric with fines and sanctions if the utility does not produce records detailing what it knew about the natural gas pipeline that exploded in San Bruno last September.
A repair project at Pacific Gas and Electric’s Milpitas facility went awry just before the San Bruno pipeline explosion last September, according to federal documents.
Records show utility crews replaced five miles of aging gas pipes under a San Bruno neighborhood less than two decades ago but stopped just short of a segment that ruptured and exploded last year.
The nation needs new solutions to improve the safety of natural gas pipelines coursing beneath neighborhoods, federal investigators said Thursday.
