Fairly soon, Pacific Gas & Electric Company will declare its pipelines inspected -- and operating safely.
The utility, which was ordered by federal regulators to take a peek and make sure its pipelines were all fine following the deadly San Bruno explosion and fire in 2010, is expected to finish its inspections in April, according to the Oakland Tribune.
The tests allow PG&E to figure out what the maximum allowable pressure in its pipelines are.
Faulty welds in a gas main under San Bruno led to the pipe rupturing after an electrical short at a PG&E substation briefly increased the pressure on the 30-inch Line 132 pipe below the Crestmoor neighborhood in San Bruno, according an investigative report in the Bay Citizen.
The faulty pipe was installed in 1956.
PG&E says its tested 6,000 miles of pipeline for maximum pressure. PG&E has now completed seven of the 12 tasks it was ordered to begin following the disaster.
