GKN Aerospace reaches $125 million settlement over Garden Grove chemical leak

Orange County District Attorney Todd Spitzer announced a $125 million settlement with GKN Aerospace Transparency Systems, Inc. and GKN Aerospace, Inc. regarding a chemical leak at a Garden Grove plant in May. The agreement, which still requires approval from an Orange County Superior Court judge, addresses a hazardous materials emergency that forced approximately 50,000 residents to evacuate their homes and businesses.

Settlement Details and Compensation

The settlement allocates up to $100 million for a claims program to reimburse residents and businesses affected by the evacuation. Eligible individuals can seek compensation for expenses such as hotel stays, loss of use, and per diem costs for meals, transportation, and lost wages. Approximately 13,000 to 17,000 households were evacuated during a five-day period beginning May 21.

First responders who handled the Memorial Day weekend emergency will be reimbursed $8,471,385.50 under the agreement. Additionally, the District Attorney’s Office will receive $15 million in penalties under state law, designated for consumer protection enforcement. GKN will also pay $1.4 million for seven years of monitoring, which includes oversight by an independent expert to ensure compliance with applicable laws and regulations.

Incident Background

The hazardous materials emergency began on May 21 when a leak was detected at the facility at 12122 Western Ave. The incident involved the cooling system of a 34,000-gallon chemical storage tank containing methyl methacrylate (MMA). Firefighters reported that the tank appeared at risk of exploding or spilling its toxic contents due to a problem with the valve used to release pressure.

Tens of thousands of residents in Garden Grove, the entire city of Stanton, and other nearby communities were forced to evacuate for several days. Authorities released a potential blast radius map to the public, showing areas that would be affected by an explosion and resulting toxic chemical plume. Ultimately, a crack in the damaged tank relieved the pressure inside it, eliminating the risk of an explosion and allowing residents to return home.

Company Response and Next Steps

In a statement, GKN said it has completed preparatory work to launch the claims program, which would begin within days of the judge's approval. The company scheduled a community meeting for Oct. 27 to provide more information about the program. "As GKN previously announced, we have been working diligently to resolve the Orange County District Attorney’s Office’s civil investigation regarding the May incident," GKN said in its statement. "Today, the DA's Office filed in court the necessary documents to initiate the process of resolving the investigation."

GKN noted that online and in-person support for the claims program would be available in English, Spanish, Vietnamese, and Korean. The company, which manufacturers parts for military aircraft and employs about 500 local residents, stated that none of the safety and monitoring requirements will go into effect until the agreement is approved by a judge.

Why it matters

This settlement represents a significant financial resolution for a major industrial safety incident in Orange County. It establishes a framework for compensating tens of thousands of displaced residents and reimbursing emergency services, while mandating long-term independent oversight of the facility's operations to prevent future hazards.
