Safety at Aliso Canyon
The safety of our employees, contractors and people in the communities we serve continues to be our top priority. We continue to work alongside multiple agencies such as L.A. County and City Fire, The Department of Public Health, CAL-OES, DOGGR and CPUC, to oversee the operation and worker safety.
 
Connecting with SoCalGas
For guidance on securing temporary accommodations, how to file a claim, and how to get free home air filtration and weather stripping to reduce odor, and other questions, the Community Resource Center is open from 10 a.m. to 8 p.m. Monday through Friday and from 10 a.m. to 4 p.m. on weekends.
 
Holiday hours for the center are:
 
December 24, Christmas Eve:         10 AM to 4 PM
December 25, Christmas Day:         Closed
December 31, New Year’s Eve:       10 AM to 4 PM
January 1, New Year’s Day:             Closed
 
 
It is located at 19731 Rinaldi St. just south of Ralphs grocery store in the Porter Ranch Town Center.   
 
Relief Well
Relief well crews continued Phase 2 drilling by reaching over 2,800 feet below the surface.  During this and subsequent phases, the team of relief well experts will positively identify the leaking well with electromagnetic ranging technology, follow it down to more than 8,000 feet deep and intercept it near its bottom. Once we intercept the well, we will pump heavy mud and fluids into the leaking well to stop the flow of gas from the reservoir and into the well. Once the flow of gas has been stopped, we will pump cement into the bottom of the well to permanently seal it. The drilling process continues around the clock, and is expected to take three to four months to complete.
 
FAA Notice
The FAA issued a temporary localized no-fly zone near the leaking well.  What this means is planes and helicopters can fly over the well as long as they are at least 2000 feet above the well. This was done to prevent any safety issues at the well site, and in the air.  
 
Air Samples & The Environment
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).  Click here for our Air Sample Updates .

Background

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. If you believe you have suffered harm or injury as a result of this incident, please complete this online form or call 213-244-5151. For temporary housing accommodations, call us at 404-497-6808.
