Aliso Canyon Natural Gas Blowout Litigation Settlement

People v. SoCalGas

On February 29, 2019, the California Attorney General (AG), together with the California Air Resources Board (CARB), the Los Angeles City Attorney, the County of Los Angeles and the Los Angeles County Counsel (together, County) entered into a Consent Decree with Southern California Gas (SoCalGas) to resolve litigation regarding the massive natural gas blowout from SoCalGas’ Aliso Canyon storage facility. Under the Consent Decree, SoCalGas is subject to injunctive terms and has paid $119,500,000 in mitigation, supplemental environmental projects (SEPs), civil penalties, and costs.

This page contains updates and links to information related to implementation of the terms of that Consent Decree.

Settlement Documents


Mitigation of Climate Impacts

As a part of the Consent Decree, SoCalGas is required to mitigate at least 109,000 metric tons of methane, which is the amount CARB estimated was emitted from the blowout. To achieve this, SoCalGas is required by the Consent Decree to pay $26,500,000 to the Mitigation Fund (“Mitigation Contribution”). The Mitigation Contribution is being invested in Mitigation Projects that are projected to achieve the required methane reductions. CARB will certify when that mitigation has been achieved.

Updates on the progress of the Mitigation Projects and relevant documents can be found on CARB's Climate Impacts Mitigation page.

Supplemental Environmental Projects and the Aliso Fund

Under the Consent Decree, SoCalGas has paid $45,400,000 to fund six pre-selected Supplemental Environmental Projects (SEPs). These funds will pay for a health study, electric school buses, air filtration in schools, electric Breathmobiles, and air monitoring in Porter Ranch and environmental justice communities. Additionally, the SEP Agreement provides for the establishment of the Aliso Fund. This fund will be for the exclusive purpose of funding environmental projects that protect public health and the environment and/or redress alleged harm caused by the blowout.

Updates on the SEP projects, the Aliso Fund, and related documents can be found on the Aliso Fund page.

Injunctive Terms

SoCalGas must comply with a number of injunctive terms under the Consent Decree. Those include:

  • (1) The maintenance of a fenceline methane monitoring system, with the data readily accessible to the public for eight years. (See Fenceline Monitoring Data.)
  • (2) The creation of an internal facility safety committee that will, for at least 8 years, meet regularly to review safety of the wells and well operations at the facility.
  • (3) The hiring of an independent safety ombudsman who will, among many other tasks, participate in the safety committee, review facility safety and make recommendations, and report to the public. (See Ombudsman’s page.)

The Aliso Fund

The Aliso Fund is administered by the Attorney General’s Office and overseen by the Aliso Fund Committee.

The Aliso Fund will be administered in accordance with the Aliso SEP Fund Administration Guidelines. The Aliso Fund Committee is in the process of drafting those Guidelines. The public will be invited to comment on the Guidelines before they are finalized.

Before the program field work was halted due to the COVID-19 pandemic, program staff and contractors tested 44 properties and found lead-based paint hazards in 34 properties (77%). Lead-based paint hazards were remediated in 3 homes before field work had to be stopped due to COVID-19. Thirty-three properties were also in progress before the COVID-19 pandemic and will be the priority when remediation work resumes.


Additional SEPs

Starting in 2026, pending the success of the Mitigation Projects discussed above, additional funds may be added to the Aliso Fund, to be used to fund additional SEPs.

If and when sufficient funds become available in the Aliso Fund, the Aliso Fund Committee will publicize at this site the process by which entities may apply for those funds. Additional details will be set forth in the in forthcoming Aliso Fund Administration Guidelines.
