On Oct. 23, 2015, a massive natural gas leak erupted at a storage well near Los Angeles. After attempts to plug the leak were unsuccessful, SoCal Gas began building a relief well to capture the leaking gas. In mid-February, the leak was fixed, according to state officials.
How big was the leak?
“It was a mega-leak, one of the biggest ever recorded,” says Tim O’Connor, California Oil & Gas Director. EDF estimates that the amount of methane leaked had the same 20-year climate impact as burning nearly a billion gallons of gasoline.
