After an industrial incident, understanding who the operator is is one of the first things affected people want — and the public regulatory record is fragmented across federal, state, and local agencies. This page assembles a sourced public profile of GKN Aerospace's Garden Grove facility from named news outlets and the canonical agency databases.
AlertRelief is not a law firm, and this page is not a corporate-liability analysis. It is a structured index of public records, every one of which links back to the original agency or outlet.
Why this matters for affected residents and businesses
If you're considering documenting a claim — for evacuation costs, property impact, business interruption, or health concerns — your attorney will start by asking who the operator is, how long they've been at the site, what they produce, and what's in the public regulatory record. The structured profile above is the same data, in one place.
The substantive facts to anchor:
- Operator. GKN Aerospace, a subsidiary of London-listed Melrose Industries plc.
- Site. Approximately 15.5 acres in Garden Grove, operating since 1993.
- Workforce. About 540 employees, per a 2024 company news release.
- What's made there. Aerospace transparencies — the windows you see in military and commercial aircraft, including canopies and cockpit windows. This is the manufacturing context for the methyl methacrylate (MMA) involved in the May 2026 incident.
- Public statement. Per ABC7 Los Angeles, GKN said it is working with officials to mitigate the risk of the leak and committed to cooperate with the investigation. At the time of writing, the company has not issued a public statement of cause.

If you live, work, or own property near the evacuation footprint, documenting your experience is the most useful step today — claim or no claim.
Document your exposure and lossesHow to read the public regulatory record yourself
Each of these databases is searchable by anyone, and each one is the canonical record for a different aspect of a facility's compliance and permitting history. We link them — and recommend you read the originals.
U.S. EPA — ECHO (Enforcement and Compliance History Online)
ECHO is the EPA's public-facing database of facility compliance with federal environmental statutes (Clean Air Act, Clean Water Act, RCRA hazardous-waste rules, and more). It shows permits, inspections, violations, and any enforcement actions over the prior five years.
U.S. OSHA — Establishment Search
OSHA's Establishment Search shows federal workplace-safety inspection history, including any inspections of the Garden Grove facility, the topics inspected, and any citations. Workplace-safety records are particularly relevant where employee-injury or whistleblower allegations are part of the public record.
California DTSC — EnviroStor
EnviroStor is California's Department of Toxic Substances Control's public-facing database of hazardous-waste handlers and contaminated-site information. It complements ECHO at the state level.
South Coast Air Quality Management District (AQMD)
AQMD's permits and compliance portal is the local-agency record for air-quality permits in the South Coast basin, which covers Orange County. Air-permit records are relevant where a facility's emissions, control equipment, or any related compliance history intersect with the incident.
California Secretary of State — Business Search
The Secretary of State business search shows GKN's California corporate registration, registered agent, and status. Useful for confirming the precise legal-entity name and structure attorneys would name in a complaint.
What this page is not
This page does not make a fault determination, assert that any specific regulation was violated, or speculate about the cause of the May 2026 incident. The Orange County District Attorney's office is investigating; no public finding on cause has been issued at the time of writing.
What it does do is organize the public record in one place, with sources, so affected residents and businesses can understand the operator they're dealing with — and so that anyone seeking accountability has a starting list of the right places to look.
