Our Five Commitments
Even though the leak is stopped, we are making the following Five Commitments to the community, and will provide updates on the status of these as we progress.
Return Home Safely
We will help residents who relocated return to their normal lives as seamlessly as possible.
100% Of Residents are Home
- Approximately 8,300 relocated residents have returned home
- Performed exterior cleaning on more than 1,200 homes, along with public parks, schools and playgrounds
- Approximately 1,500 homes received interior home cleaning
Methane at Pre-Leak Levels
- Third-party indoor air testing for methane and mercaptans showed no levels of concern
- Thousands of outdoor air samples collected by health and environmental agencies have consistently shown that air quality has returned to pre-leak levels
- View our daily air reports here
Expand Community Resources
We will continue to provide dedicated customer service to the impacted residents.
38,000 Visits at CRC
- Local residents have been assisted at the Community Resource Center (CRC) since it opened in December
Approximately $500 Million Paid in Relocation Costs
- To date, our team has reviewed and processed over 59,000 reimbursements
- 300 reimbursement processors and SoCalGas community liaisons are working diligently to respond to residents’ inquiries and requests
Air Filtration Systems
- More than 38,000 air filtration systems have been installed in 10,500 homes, 60 schools and 160 businesses
Understand What Caused the Leak
We will cooperate with regulatory agencies on their investigation of what caused the leak.
SED and DOGGR Investigation
- The California Public Utilities Commission Safety Enforcement Division (SED) and the Division of Oil, Gas and Geothermal Resources (DOGGR) are onsite at Aliso Canyon investigating the cause of the leak
- SED and DOGGR have selected an independent third-party contractor to conduct a root cause analysis
- SoCalGas continues to cooperate with the agencies and is supporting the investigation
- SoCalGas Supports SB 380
Assure Integrity of All Wells
We will accelerate the inspection of our other storage wells at Aliso Canyon and support regulatory policies that adopt best safety practices for all storage facilities.
Well Testing and Verification
- All 114 wells at the Aliso Canyon facility undergoing rigorous tests to verify operational safety
- Only wells that pass the full battery of six DOGGR required tests will be considered for storage operations, with the balance permanently taken out of service
- Only after all active wells meet DOGGR’s requirements will DOGGR confirm the field can be put back into service

Address Environmental Emissions
We will develop and implement a plan to mitigate the greenhouse gas emissions of the leak, at our expense – not at the expense of our customers.
- We have completed a thorough measurement of the gas inventory in the Aliso Canyon reservoir and determined the most likely level of actual emissions are slightly lower than, but in line with, preliminary estimates made by the California Air Resources Board (ARB), and estimates made by third-party scientists.
- We are exploring methane emissions mitigation from multiple sources, such as dairies and landfills, and have already signed letters of intent with several California dairies
- We will finalize our mitigation plan in the coming months and it will be made public just as soon as it's completed and reviewed by the appropriate regulators
