It’s been four years since employees at SoCalGas discovered the Aliso Canyon Gas Leak. More than 100,000 metric tons of methane and other chemicals were leaked into the air over a combined period of 100 days in 2015 and 2016.

The cause of the leak, documented in a report released earlier this year by state regulators, was a rupture in an underground natural gas well, whose  metal lining was corroded by groundwater. The report also pointed a finger to SoCalGas, faulting the company for neglecting to monitor or maintain its wells.

Larry talks with KPCC’s Sharon McNary on the worse natural gas leak in US history.
