Massive Gas Pipeline Rupture in California — Interstate 5 Shut Down, Shelter-in-Place Ordered as Orange Haze Fills the Sky

Orange Plume Wafts From Ruptured Gas Line That Prompted Shelter-in-Place Order. A gas pipeline rupture in Castaic, California, on Saturday, December 27, prompted a shelter-in-place order and the closure of Interstate 5. Video filmed by Samina McLeod shows an orange haze billowing from the side of a mountain. She said the footage was taken at about 4:17 pm local time. The interstate was later reopened and the shelter-in-place was lifted.
