The Straits Times World NewsNewsom Declares Emergency in Orange County; EPA Head Says Chemical Tank Will Likely Fail
California Governor Gavin Newsom declared a state of emergency in Orange County after a chemical storage tank containing 5,000 to 7,000 gallons of methyl methacrylate began showing signs of instability at a manufacturing facility in Garden Grove. EPA Administrator Lee Zeldin stated on CNN that the tank will likely fail, with the most likely scenario being a low-volume release that can be contained. However, he warned that the most catastrophic scenario involves an explosion that could trigger additional tank explosions, prompting large-scale evacuations. Emergency responders, including the Orange County Fire Authority, are working to keep the tank temperature below 85 degrees Fahrenheit using drones for monitoring. Zeldin emphasized that this is currently an emergency response, and the scale of the environmental response will depend on what happens when the tank fails. The tank first showed instability on Thursday, with fears escalating on Friday.
