RANCHO CUCAMONGA >> Southern California Gas Company workers have removed one of two gas extraction machines from a Alta Loma neighborhood following nearly three weeks of cleanup work from a gas leak, officials said.
The extraction machine on Archibald Avenue was stopped Friday night and removed Saturday morning, according to a SoCal Gas news release.
Testing over a day shows that methane levels in the soil at Archibald are safe, but that additional testing will happen over the weekend to make sure they stay that way, according to officials.
Another extraction machine at La Gloria Drive and Jadeite Avenue is still being used to extract methane. Levels there have “dropped significantly,” the release says, but work is expected to continue for several more days.
A gas leak was reported in on May 8 in a pipe on Archibald Street and La Gloria Drive in the Alta Loma neighborhood. Though crews repaired the leak, work has been continuing in the area for nearly three weeks.
On May 19, South Coast Air Quality Management District inspectors began investigating the incident after a member of the public complained. Officials there said that levels of methane were “elevated.”
Methane, a colorless and odorless gas, is the main component of natural gas. High levels of methane are known for being flammable, SCAQMD spokesman Sam Atwood said, but the levels found in Alta Loma are not high enough for that to be an issue.
