Music producer and sound engineer Matt Pakucko works in his Porter Ranch home near the site of the Aliso Canyon storage field where gas has been leaking in Porter Ranch, California, United States, January 21, 2016. Long before the leak, utilities and national industry groups were raising alarms about the danger of aging underground storage infrastructure. Under state regulations, the leaking well’s owner, Southern California Gas, faces a maximum penalty of $25,000 for the leak near Los Angeles, which is unprecedented in scale. The well has spewed methane - a potent greenhouse gas - since October and displaced thousands of people in nearby Porter Ranch. Pakucko moved into a hotel with his girlfriend after experiencing headaches, a hurt throat, watering eyes, and a persistent cough after the gas began to leak.
