Orange County evacuations expand as Garden Grove chemical tank nears failure
A 34,000-gallon tank of methyl methacrylate at a Garden Grove aerospace plastics facility is in crisis, prompting evacuations across six Orange County cities (Garden Grove, Cypress, Stanton, Anaheim, Buena Park and Westminster). Crews are cooling and monitoring the tank, with a temperature threshold that would trigger a full evacuation. The tank could either leak thousands of gallons or explode; air-quality monitors, drones, and road closures are in place as officials assess when it’s safe to lift the orders.
