“SoCalGas had lenient requirements for infrastructure record keeping, no comprehensive risk management plan, and no testing programs or plans in place to remediate substandard wells,” concluded Najmedin Meshkati, University of Southern California professor of civil and environmental engineering and senior author on the report. The study was published in the Journal of Sustainable Energy Engineering.

In addition to its notable contribution to global warming, the massive methane leak also required the evacuation of two schools and at least 8,000 residents for months while SoCalGas tried to stop the leak.

The California Public Utilities Commission also issued a report evaluating the failed storage well at Aliso Canyon, and noted that “severe external corrosion was observed in the failure areas.” Based on these reports, it appears that SoCalGas had a policy of allowing its gas storage wells to operate until they failed, such as at Aliso Canyon.

DeSmog reached out to SoCalGas for comment on the University of Southern California study but did not hear back.

A History of Industry Self-Regulation

In theory, outside inspectors could have potentially caught some of these safety issues during regular evaluations of the infrastructure. But as the University of Southern California’s report details, that is not how the natural gas storage industry operates in the U.S. Instead, its description of the circumstances leading to the leak reads as much like a recipe for future disaster as an analysis of past failures. Previously, the industry has largely been allowed to self-regulate and the trend continues today.
