Pacific Gas & Electric Co. says a gas pipeline that exploded in Central California had been inspected twice in April for gas leaks, and no leaks were found.
PG&E said Sunday that its crews did a ground survey of the pipe on April 1, and an aerial survey on April 16. The utility has said a vehicle damaged the pipeline.
Authorities say Friday’s explosion on a Fresno County Sheriff’s gun range occurred while a county equipment operator was building up a dirt berm. PG&E said it detected a drop in pressure in the line seven minutes before it received a report of the explosion.
The blast sent 11 people to the hospital, four of them with critical injuries.
