Garden Grove tank: no active leak

About 50,000 people remain under evacuation orders even as California officials said there is currently no active leak from the failing Garden Grove chemical tank, with crews still cooling a vessel holding 6,000 to 7,000 gallons of methyl methacrylate at GKN Aerospacenbclosangeles.com kcra.com apnews.com). The key read is that this is still a containment story, not an all-clear: CBS reported the tank was rising about 1 degree per hour and was at 90 degrees after starting the day at 77, so the absence of an active leak trims immediate tail risk but does not remove rupture or fire risk if cooling fails cbsnews.com. For Melrose, GKN’s parent, that keeps this in plant-specific headline-risk territory rather than a broader aerospace-supply issue, at least for nowgoogle.com nytimes.com). What changes the read is simple: any confirmed leak, ignition, or extended shutdown turns this from local emergency management into a real liability and supply-chain event.
