A crew from Pacific Gas & Electric is expected to have completed repairs associated with a leaking valve in a three-inch gas main in the 3900 block of Sand Hill Road by this afternoon (May 6), PG&E says. The leak itself has been repaired and the crew is filling in the hole along the side of the road, a company spokesperson said.
In the meantime, drivers and cyclists should use Manzanita Way, Winding Way, Mountain Home and Portola roads as a route around the work site, said Sean Rose, public works director for the town of Woodside.
The section of pipeline taken out of service to repair the leak will remain out of service for the foreseeable future while PG&E considers further repairs, PG&E spokeswoman Melissa Subbotin said. The repairs may include relocating the pipe so that it's not 11 feet underground and "wouldn't require the level of excavation that this specific project required," Ms. Subbotin said.
The depth of the hole required crews to install shoring to prevent the earthen walls from collapsing, which led to the decision to close the road, Ms. Subbotin had said earlier.
"The leak has been addressed and remediated," she said Friday morning (May 6). "There was no danger to the public or the crews. That's our number one priority."
The leak occurred in an area not in the immediate vicinity of gas customers, Ms. Subbotin said. Customers served by that main had their gas supply rerouted as soon as the leak was discovered, with no interruption of service, she said.
PG&E uses Picarro leak-detection technology. The technology is mounted on a vehicle and can sense leaks at driving speeds, according the website picarrosurveyor.com. PG&E crews also perform leak-detection surveys on foot.
