SHERMAN OAKS—The Southern California Gas Company’s Aliso Canyon facility caught fire, causing concern for the facility that was at the forefront of the largest gas leak in United States history.

The fires were reported at 12801 N. Tampa Avenue, at 1:27 a.m. and 7:29 p.m. on Thursday, June 9. Both small shipping-container fires were quickly put out according to Erik Scott of the Los Angeles Fire Department, as reported by the Los Angeles Daily News.

The cause of the fire is under investigation, but arson is not currently being viewed as the cause. One of the fires was found in a drum near a construction trailer at the facility, while the second fire caught blaze in a shipping container.

The Southern California Gas Company operated Aliso Canyon facility and has been under scrutiny since the costly gas leak took place. Residents in the Porter Ranch area were forced to leave their homes for long periods of time after illnesses, headaches, and nosebleeds arose from the large quantities of gas fumes in the air. Some residents are still seeking restitution for the situation.
