Federal authorities executed a search warrant Wednesday at the GKN Aerospace facility in Garden Grove, California, where a chemical tank overheated last month, prompting the evacuation of approximately 50,000 residents. The FBI and Environmental Protection Agency (EPA) are investigating potential violations related to the storage and handling of methyl methacrylate, a highly flammable chemical used in plastics production.
Immediate Action & Core Facts
The FBI and EPA served a federal search warrant at the facility, authorized by a federal judge. The warrant allows agents to seize documents, records, and samples related to the storage, use, and disposal of methyl methacrylate. The investigation follows a May 21 incident where a 34,000-gallon tank containing the chemical overheated, releasing vapors and raising concerns of a potential explosion.
Deeper Dive & Context
Incident Details
On May 21, a malfunctioning valve in a 34,000-gallon tank caused pressure buildup, leading to the release of methyl methacrylate vapors. Authorities evacuated residents within a 1.5-mile radius due to the risk of explosion or toxic release. The crisis was resolved when a crack in the tank allowed pressure to dissipate, averting a catastrophic event.
Investigation Scope
The search warrant authorizes the seizure of records related to cooling systems, risk analyses, and safety equipment used with methyl methacrylate. Investigators are also seeking samples from containers suspected of holding the chemical. The FBI Los Angeles Field Office confirmed the ongoing investigation but declined further comment.
Company Response
GKN Aerospace, which operates the facility, stated it is cooperating with authorities. The company is a division of Melrose Industries, a U.K.-based aerospace manufacturer. Residents affected by the evacuation have filed multiple class-action lawsuits against the company, alleging negligence and seeking compensation for property damage and loss of use.
Chemical Hazards
Methyl methacrylate is used in plastics and coatings, including Plexiglas and dental prosthetics. Exposure can cause respiratory problems, neurological issues, and irritation to the skin, eyes, and throat. The chemical remains in the holding tank, and cleanup efforts are ongoing.
Legal and Regulatory Context
The investigation is focused on potential violations of Title 42, which outlines the “general duty to prevent accidental release of extremely hazardous substances.” The Orange County District Attorney’s Office has also been involved in the investigation since the incident occurred.
