Aliso Canyon Air Quality Notifications
Aliso Canyon Storage Facility

Yesterday, as part of the DOGGR’s Comprehensive Safety Review, our contractor was cutting pipe using a small tool and a common cutting agent called bromine triflouride. The tool used to deliver the cutting agent did not empty properly once the cutting was completed and a small amount of material (estimated as less than 1 cubic foot) was released into the air. There was no threat to public safety, and SoCalGas informed the appropriate agencies about the release.
|November 21, 2016||Today (Monday, November 21) as a result of a mechanical tool malfunction, a very small amount of material used as part of the well workover process was released on a well pad at Aliso Canyon. No injuries were reported. The release has been stopped. Out of an abundance of caution, one of our contractors temporarily evacuated its employees from the well pad. OES has been made aware. There is no risk to the health and safety of Porter Ranch and the surrounding community.|

This afternoon at approximately 4:50 p.m., SoCalGas discovered a small natural gas leak in an above ground pipe at the Aliso Canyon storage facility. The leak was quickly isolated and stopped.
The leak was not in a well, but a pipe used to withdraw natural gas from the reservoir.
The cause of the leak has not yet been determined. However, our initial findings indicate the leak began only a short period of time before its discovery and that the release of natural gas was small.
We do not anticipate that the released gas will be noticeable in the surrounding community. At no point was there a threat to public safety.
SoCalGas has notified the relevant agencies and is in the process of making permanent repairs.
