SANTA ROSA (KCBS) – Pacific Gas and Electric has reduced pressure on a section of its high pressure gas transmission line between Santa Rosa and Healdsburg after an inspection found some possible irregularities.

An inspection was done in March using a high tech device known as “a smart pig” that traveled through the 12-inch diameter pipeline.

KCBS’ Anna Duckworth Reports:

PG&E spokesman Brian Swanson said it takes a few months to analyze the smart pig’s data, but it was found to have picked up some anomalies.

“The sensors are picking up what might be a dent, a sign of corrosion or it might be an issue with a weld that we might want to take a closer look at,” he said.

Swanson said PG&E reduced pressure in the line by 11 percent in late July while more tests are done on exactly what the device detected.

“Anything we find, we want to take a closer look at. Anything that we determine could affect public safety, we’re not going to wait,” Swanson said. “We’re going to go ahead and make the repairs immediately.”

The pressure reduction was under new safety guidelines adopted by the utility after last September’s deadly gas pipeline explosion in San Bruno.
