10 Years Since Aliso Canyon: Disaster Was Wake-up Call for US on Dangers of Underground Gas
Debate continues over Aliso Canyon's future as regulators balance safety concerns with its role in supplying 40% of California's electricity, with capacity set to be reduced by 10 billion cubic feet.
- On October 23, 2015, Well SS-25 at the Aliso Canyon underground gas storage facility began a nearly four-month leak that released 109,000 metric tons of methane and relocated 8,000 families.
- Well SS-25 at Aliso Canyon, drilled in 1953 and repurposed for storage, failed due to external corrosion likely caused by groundwater contact, state regulators determined.
- Researchers are conducting a $21 million UCLA-led Aliso Canyon Disaster Health Research Study, with early findings linking low birthweight to 666 exposed cases from over 1 million records.
- CPUC staff recommended lowering the facility's maximum storage to 58.6 Bcf, but last December the CPUC board voted to keep Aliso Canyon operating for energy reliability and consumer price control.
- The Porter Ranch Community Air Monitoring Project provides real-time methane data and sent an Oct. 3 alert later retracted; SoCalGas said it added safety measures, while nearly 36,000 plaintiffs sued.
