Break Free From Plastic Members React to Toxic Methyl Methacrylate Leak in Garden Grove, California

Break Free From Plastic

Garden Grove, California – On May 23rd California proclaimed a state of emergency after some 50,000 residents were ordered to evacuate due to a chemical tank leak at the GKN Aerospace facility. That tank held 7,000 gallons of methyl methacrylate or MMA, a toxic and highly flammable chemical used to make plastic, adhesives and resins. Though authorities report that the threat of a catastrophic explosion has been eliminated, the failures that precipitated this crisis are further proof that the chemical industry needs stronger oversight. Yet the U.S. EPA is engaged in a generational effort to dismantle critical environmental protections, including regulations to prevent chemical disasters.

June 9, 2026. Update: Further investigation has shown that several days before the leak, the city of Garden Grove issued permits for GKN to expand its facilities in order to meet the US and Israel’s increasing demand for F-35 fighter jets. Days after the Strait of Hormuz was closed, an explosion at the Valero refinery in Port Arthur, TX, shook homes more than ten miles away and sent a plume of toxic black smoke into the surrounding community. Valero has been the largest receiver of Venezuelan crude after the US's military intervention in January. Both the explosion in Port Arthur and the averted catastrophe in Garden Grove underscore the link between the toxic industries harming communities at home and the military-industrial complex driving US imperialism abroad.

Break Free From Plastic members respond to the toxic chemical leak

Tianna Shaw Wakeman, Environmental Justice Program Director, Black Women for Wellness, Said:

“This past week in Southern California, communities in East L.A. faced a 2,400 gallon oil spill from a ruptured pipeline while evacuated Garden Grove residents spent the weekend fearing a deadly explosion. These events are connected. Like most chemicals used to make plastic, the MMA leaked in Garden Grove is derived from oil and gas. 

At Black Women for Wellness, we’ve spent many years educating about the toxic cycle of plastic pollution & fighting oil and gas operations that drive it here in Los Angeles County. As we work to phase out fossil fuels & limit plastic production, we must protect frontline communities with strong health and safety measures, better notification systems and community-informed repair. Oil transport and toxic chemical storage most often occur in communities of color, where industries continually place residents in harm's way but aren't being held accountable. Industries must pay for clean up and harms incurred.”

Julia Cohen, Co-Founder and Executive Director, Plastic Pollution Coalition, Said:
“While the imminent crisis of a chemical explosion appears to have been stemmed, make no mistake that the chemical disaster in Garden Grove, California, is still unfolding. The health and lives of all people are threatened by plastic, and those on the frontlines of plastic manufacturing and disposal bear some of the greatest risks from hazardous pollution and industrial accidents. Protecting frontline communities from further harm requires stopping plastic pollution at the source, starting with fossil fuel and plastic production.”

Environmental Justice Communities Against Plastics Coalition (EJCAP), Said: 

“Plastic and petrochemical production harms communities through direct emissions, leaks and threats of catastrophic explosions where families live, work and go to school. Tens of thousands of residents should never have to evacuate their homes because of a preventable industrial threat. Plastics and petrochemicals, including MMA, are a public health emergency that must be prevented at the source. Garden Grove communities deserve better.”

Yvette Arellano, Executive Director, Fenceline Watch, Said:

“Evacuation orders might have been lifted for Garden Grove residents, but this is just the beginning of a long and necessary fight for their human right to a clean, healthy, and sustainable environment. The GKN plastic facility's toxic release into the surrounding community is a situation that our communities along the Houston Ship Channel are very familiar with. Community members are urged to document symptoms not only in themselves but also in small pets and children, as their bodies are smaller and more susceptible to lower levels of exposure. 

Multigenerational effects are the real threat. We are learning everyday of the new health impacts plastics have on our bodies, and the true toxic harm won't be clear until much later on. From the petrochemical explosions we face in Houston, or the vinyl chloride train derailment in Ohio, we know EPA and other well-meaning officials may be underestimating the true cost this disaster has inflicted on Garden Grove.” 

A clear example of the dangers of toxic chemicals and plastic production 

Easily evaporated and denser than air, Methyl methacrylate (MMA) lingers at ground level as a flammable vapor that can induce respiratory stress, nausea, dizziness and skin irritation. Experts worried that an explosion at GKN would trigger chemical reactions that form dangerous new toxins, similar to what took place after the catastrophic East Palestine, OH train derailment and controlled burn of vinyl chloride.

Chemical disasters are not uncommon. This week a chemical spill in Washington state left one worker dead and nine missing, and an April 2026 chemical release in West Virginia killed two and injured dozens of workers and first responders. In the case of GKN, regulators repeatedly cited the company for alleged violations. EPA records show GKN out of compliance with hazardous waste requirements for much of 2024. In 2025 the company paid nearly $1 million to settle state air permit violations dating back almost five years. 

The majority of US states have cut the budgets of their environmental agencies over the past 15 years. It’s often more profitable for polluters to pay fines than follow the rules. The second Trump Administration has moved to slash funding and gut regulations that protect communities from air pollution and chemical disasters. Since 2025, EPA enforcement has collapsed

“Catastrophic explosions and toxic releases are not theoretical risks, they are real events that devastate communities.”  – Marc Bloom, former EPA staffer

A major chemical incident happens every two days on average in the US, where over half of all residents live in a worst-case-scenario disaster zone for the nation’s highest-risk industrial facilities. Like plastic pollution, chemical safety is an ‘everybody’ issue, and there are policy solutions: Federal officials must fully enforce the Emergency Planning and Community Right-to-Know Act, including local planning obligations. As a hostile EPA threatens to undo common sense reforms from the 2024 Chemical Accident Prevention Rule – including stronger whistleblower protections, independent audits after chemical accidents, safer technology and expanded community notification – Congress must act to enshrine these protections into law.
