Melrose said the incident, detected on 21 May, involved a storage tank containing methyl methacrylate, a chemical used in high‑strength aerospace acrylics, with GKN staff taking immediate action and notifying emergency services.
The Orange County Fire Authority ordered mandatory evacuations for parts of the local community on 22 May while response teams worked to stabilise the site.
Melrose said technical specialists, emergency responders and local authorities had since made "positive progress", allowing the evacuation zone to be significantly reduced on 25 May.
Local officials confirmed that no injuries, leaks or contamination had occurred, and Melrose added that GKN was now working with customers on operational recovery and supply plans.
