The largest gas blowout in the history of the United States took place in the suburbs of Los Angeles.

The Aliso Canyon gas storage facility is located adjacent to several communities in the northwest San Fernando Valley. The facility is owned and operated by SocalGas, a subsidiary of Sempra Energy. SoCalGas is an investor-owned utility and their operations are regulated by the California Public Utilities Commission.

On a typical day the Aliso Canyon gas storage facility routinely discharges carcinogens including formaldehyde, benzene, toluene, ethyl-Benzene and Xylene (BTEX), acetaldehyde, and uranium. Other chemicals released have included acrolein, ammonia, carbon dioxide, nitrogen and oxides. This is just a partial list - SoCalGas has refused to disclose the full list of chemicals they use. 

It's important to note that when the facility is operating normally, the community is exposed to these chemicals. During a blowout or leak, larger quantities of these chemicals are emitted.

October 2020 marks the 5-year anniversary of the start of the blowout. The negligent facility is still open and operating. As a matter of fact, in the past year, they ramped up production by 3,000 percent. Despite promises to shut the facility down, our elected officials are allowing the company to increase production and compromise the health and safety of people in LA county.
