Southern California Gas Co. said it "continues to assess conditions" at the Aliso Canyon natural gas storage facility following the Saddleridge Fire, which affected the community of Porter Ranch near Los Angeles.

Other than a small fire on the property, which was extinguished Oct. 15, no damage has been found and there are no indications of leaks at the facility, SoCal Gas said. The utility said it is working with fire department officials to determine the source of that small fire. 

But environmental watchdogs are not convinced the fire should be so easily dismissed. Aliso Canyon was the site of a massive accidental methane release from October 2015 to February 2016.

"The mysterious fire at the Aliso Canyon gas storage facility is alarming, especially as state and local agencies have yet to pinpoint the cause," Alexandra Nagy, Food & Water Watch's California state director, said in a written statement.

"We call on Governor Newsom to immediately order state agencies to close down the Aliso Canyon facility," she said. "It's time for him to choose the safety of families over fossil fuels."

Sen. Henry Stern (D-Canoga Park) on Oct. 15 issued a news release calling for "full transparency" about the fire.

"Any mystery at Aliso Canyon, especially one involving a fire, is unacceptable given the history of the blowout and the legacy of distrust that follows it," Stern said. "We are pressing for answers immediately. Even if the fire does not pose an immediate public safety risk, the public deserves transparency."
