Overheated Tank Triggers Mass Evacuation
On May 21, a storage tank at GKN Aerospace’s Garden Grove plant in Orange County began to overheat. The tank contained roughly 6,000-7,000 gallons of methyl methacrylate, a highly flammable liquid used in acrylic production. Emergency officials ordered the evacuation of about 50,000 residents, displacing them for three to five days until the tank was stabilized.
Timeline and Key Figures
The overheating began on May 21; evacuation orders followed the Memorial Day weekend (May 25-27). The next Wednesday FBI agents served a search warrant, and the EPA joined the next day. Attorneys Richard McCune, Sean Litteral and GKN senior vice president Steve Carlin have spoken publicly.
Criticism & Opposition
More than 30 lawsuits, covering over 100 plaintiffs, include ten federal class actions and 21 state cases (1-31 plaintiffs each). About 3,000 businesses closed and another 3,000 lost revenue after the evacuation. Plaintiffs claim GKN failed to maintain the tank’s cooling system, valves and monitors, breaching its duty and causing displacement and losses.
Official Statements & Responses
GKN Aerospace said it respects the legal process and will address the lawsuits promptly. Senior vice president Steve Carlin expressed regret and pledged cooperation. The FBI and EPA confirmed joint evidence-collection but declined comment on any criminal investigation.
On-the-Ground Accounts
Debbie Cohran, living 500 feet from the plant, said she received evacuation notice hours late and suffered nausea and headaches. Melanie Rose Burciaga left the hospital after giving birth when orders came. Juan Diego Orozco needed emergency care for breathing difficulty, vomiting and a headache after exposure.
Conflicting Reports & Gaps
Sources differ on plaintiff numbers, citing “more than 30 lawsuits” versus “more than 100 individuals.” The EPA’s note that it “doesn’t comment on criminal investigations” leaves the scope of possible federal violations unclear.
Verbatim Quotes
- “GKN respects the legal process and will respond to these lawsuits in due course.” — GKN Aerospace spokesperson
- “Our data shows approximately 3,000 businesses were forced to shut down because of the evacuation, and at least another 3,000 businesses right outside the evacuation zone while not forced to close, but had their revenue dropped considerably because of the tank failure and evacuation,” — Richard McCune, attorney for business plaintiffs
- “We trust that the search will uncover important information and materials related to this crisis,” — Sean Litteral, attorney for individual plaintiffs
- “Exposure to the chemical can cause serious respiratory problems, neurological issues and irritation to the skin, eyes and throat, according to the EPA.” — U.S. Environmental Protection Agency
Outlook
Federal air-quality monitoring will continue for months. Law professor Adam Zimmerman said the federal cases will likely be consolidated under a single judge and many state cases could be moved to federal court. The FBI probe of storage and disposal practices may shape future regulation.
