Aliso Canyon Updates
Updated November 4, 2015
On October 23, SoCalGas crews discovered a leak at one of its natural gas storage wells at its Aliso Canyon storage field. In response, we activated the appropriate procedures, alerted public officials and began addressing the leak.
We recognize that the smell of the odorant in natural gas is unpleasant, and we sincerely apologize for the annoyance and concern this odor is causing the Porter Ranch community and surrounding areas. However, the leak poses no threat to public safety. It is located in an isolated, mountain area more than a mile away from and more than 1,200 feet higher than any home or public area. Scientists agree natural gas is not toxic and that its odorant is harmless in 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 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 and Gas & Geothermal Resources, and the South Coast Air Quality Management District (SCAQMD).
Update for Activities – November 3
Our team of well management experts continued assembling the specialized equipment needed to carry out the next steps toward stopping the leak. The setup of this equipment is on-schedule and expected to be completed by Wednesday, November 4. We continued to monitor the leak 24/7 to ensure conditions remained safe.
To keep public officials updated on the progress and conditions at the site, SoCalGas participated in the regular, daily briefing with representatives of the local health, fire and hazmat agencies.
A team of our environmental specialists and retained experts continued conducting daily air quality 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 concern, we are continuing to conduct this sampling to reassure the community. The samples we are taking are in addition to those being taken by the SCAQMD. Results from our tests should be available on this site later today.
We also continued to answer questions, meeting with 20 neighbors at our public information booth and responding to calls. We encourage anyone with questions to visit our booth, check updates at this website, email us atAlisoCanyon@SoCalGas.com or call us at (818) 435-7707. The booth will be open every day from 10 a.m. to 5 p.m., near the gates of our facility at 12801 Tampa Avenue in Porter Ranch.
