California lifts evacuations after chemical tank risk eliminated
Tap title to read story
Garden Grove, Calif. — Southern California officials lifted the final evacuation orders Tuesday night for about 16,000 residents who had been displaced by an overheating chemical tank at the GKN Aerospace facility, allowing them to return after earlier weekend evacuations that affected roughly 50,000 people and prompted emergency declarations, and state and federal agencies coordinated monitoring and public safety measures.
Officials said firefighters stabilized the tank after a crack unexpectedly relieved pressure over the Memorial Day weekend, averting a potential BLEVE; health authorities reported no detected contamination and will monitor air quality, sewers and storm drains for several months. Residents reported minor symptoms during evacuation, and officials continue assessments and housing support this week.
