Aliso Canyon Updates
SoCalGas began drilling a relief well at its Aliso Canyon storage facility the evening of December 4 in order to stop the flow of gas leaking from an adjacent well. This relief well is being drilled to intercept the leaking well at more than 8,000 feet below ground. The relief well drilling process, which is expected to operate 24/7, should take three to four months to complete. Once the relief well is connected to the leaking well, SoCalGas will pump fluids and cement into the bottom of the leaking well, and stop the flow of gas and permanently seal the well.

Update on Activities: December 3
- Filed for permit to begin drilling. Preparations at the relief well drilling site continue and drilling is anticipated to begin this weekend.
- In support of the local community, we are currently in the process of establishing a Community Resource Center to provide in person information on relocation, claims and answer questions. For now, we continue welcoming our neighbors at our public information booth, which we staff as weather permits. In the event of inclement weather, please remember, neighbors can check updates on this website, email us at AlisoCanyon@SoCalGas.com or call us at (818) 435-7707. The booth is located near the gates of our facility at 12801 Tampa Avenue in Porter Ranch, and its hours (weather permitting) are from 10 a.m. to 5 p.m.
- In addition, we are developing a dedicated website for residents, set to launch next week. In the interim, we will continue to keep the community updated via our website.
- SoCalGas will continue to monitor the well pressures 24/7 to ensure conditions remain safe.
- A team of our environmental specialists and retained experts will continue conducting daily air sampling and monitoring at several representative sites both within the leak site and the community. Although experts agree that natural gas is not toxic and that the levels of the odorant in the natural gas are too low to be a long-term health concern, we are continuing to conduct this sampling to provide the community with more information. The samples we are taking are in addition to those being taken by South Coast Air Quality Management District (SCAQMD). Air sampling results from our tests are available at www.socalgas.com/newsroom/aliso-canyon-updates/air-sample-results.
On October 23, SoCalGas crews discovered a leak at one of the natural gas storage wells at its Aliso Canyon storage field. In response, we activated the appropriate procedures to begin to address the leak.
We regret that the smell of the odorant in natural gas is unpleasant and that some people are sensitive to the odor, and we sincerely apologize for the annoyance and concern this odor is causing the neighboring communities. However, the leak does not pose an imminent threat to public safety. The well is located in an isolated, mountain area more than a mile away from and more than 1,200 feet higher than the closest home or public area. Scientists agree natural gas is not toxic and that its odorant is harmless at the minute levels at which it is added to natural gas. In outdoor locations such as this, natural gas quickly dissipates into the air, greatly reducing the possibility for ignition and further diluting the gas as it reaches the public. The human nose is amazingly sensitive and can detect the smell of the odorant at levels much lower than any level of concern.
We have assembled a world-class team of experts, and we are working as quickly as safety will allow to stop the leak. In addition, we are in regular communication with L.A. City and County Fire and Hazmat Departments, the L.A. County Department of Health, the California Division of Oil, Gas & Geothermal Resources, and the South Coast Air Quality Management District.
We apologize for how this incident may be affecting you, and we appreciate the community's ongoing patience as we work as quickly and safely as possible to resolve this situation.
