About two weeks before state officials will vote on the future of the controversial Aliso Canyon underground natural gas storage facility, which became the site of a massive gas leak nine years ago, a group of 100 scientists sent a letter to Gov. Gavin Newsom urging him to shut down the facility.

For four months in 2015 the gas leak spewed nearly 100,000 metric tons of methane, the largest methane release in U.S. history. The disaster forced 32,000 residents in Porter Ranch, Granada Hills and Chatsworth —  and several other communities in the San Fernando Valley — to evacuate and many experienced nosebleeds, dizziness and respiratory issues.
