Was the noise coming from the train tracks or the PG&E gas pipeline?

I think it was coming from the yard between Park and

the train tracks near Page Mill. Is that PG&E?? It sounded

like escaping air. Maybe part of the pipeline repair/test

process?

Heard that several people called PAPD and the PD reported that it was PG&E working on the gas line near Park and Page Mill. FYI, the SJMercury is reporting that the leak in Palo Alto was finally located: Web Link

Palo Alto loud noise is helium gas being released from gas lines by PG&E. They found the hole they were looking for so now we're all safe. via my neighbor @dbenatar on Twitter

The city sent this message via CANS:

Subject: PAF- PGE Venting

This is a message from the Palo Alto Utilities Department. PG&E natural gas pipe testing activity is the reason for the loud noises you may have been hearing since roughly 6:30 tonight. The noise is caused by PG&E venting non-volatile gas out of its pipeline. There is no danger to the public from the release of this non-volatile gas. The venting should be complete by 10:30 pm. The loud noises should dissipate earlier, roughly by 9:00 pm. Once the venting is completed, PG&E will repair a leak detected in its gas pipeline. PG&E will work through the night to make the pipeline repair and will pressure test the pipe with water following the repairs. Traffic controls on Page Mill will remain in place during this work.

Non-volatile gas? Must have meant non-flammable gas. Sigh...
