The Trump administration on Friday unveiled a proposal to loosen federal rules governing emissions from sterilizer plants that release ethylene oxide, a gas that federal regulators say is linked to several forms of cancer. The move has quickly ignited debate between those who argue the change is necessary to protect the medical supply chain and critics who warn it could expose nearby communities to greater health risks.
The Environmental Protection Agency announced the proposed rule change, which would scale back certain requirements placed on sterilizer facilities that emit ethylene oxide. The chemical plays a major role in sterilizing medical equipment but has also long been a source of concern due to its potential health impacts.
According to the EPA, ethylene oxide exposure has been associated with serious illnesses, including lymphoma, myeloma, lymphocytic leukemia and breast cancer in women. In 2022, the agency identified elevated cancer risks in nearly two dozen communities located near plants that release the gas, highlighting the tension between industrial use of the chemical and the well-being of nearby residents.
Under a rule finalized in 2024 during the Biden administration, the federal government sought to reduce emissions from sterilizer plants by 90 percent. That effort was aimed at sharply cutting the amount of ethylene oxide released into surrounding communities.
The proposal announced Friday would roll back parts of those requirements. If finalized, some emissions controls established under the Biden-era rule would no longer apply, while other restrictions would be reduced.
EPA Administrator Lee Zeldin defended the proposal, arguing that the administration is attempting to balance public health concerns with the need to ensure the availability of essential medical devices.
“The Trump EPA is committed to ensuring life-saving medical devices remain available for the critical care of America’s children, elderly, and all patients without unnecessary exposure to communities,” Zeldin said in a statement.
Ethylene oxide is widely used to sterilize certain medical devices that cannot easily be cleaned through other methods, making it a key component in the medical supply chain. Administration officials say overly restrictive regulations could disrupt the production and sterilization of those devices, potentially affecting hospitals and patients who rely on them.
The administration has already taken steps in that direction. Last year, roughly 40 sterilizer plants were temporarily exempted from the existing emissions standards.
By contrast, the Biden administration’s earlier rule allowed for exemptions only under what it described as “exceptional circumstances.” Facilities seeking relief would have needed to demonstrate they could not meet the standards.
Critics say the new proposal could weaken protections for communities that have already faced long-term exposure to the chemical.
Darya Minovi, a senior analyst for the Center for Science and Democracy at the Union of Concerned Scientists, sharply criticized the move in a statement.
“This decision is a reckless and self-serving handout to big industry,” Minovi said, calling it “an affront to communities that have unknowingly lived with ethylene oxide exposure for decades.”
She also argued that the administration’s approach shows a lack of concern for public health.
“These actions show, yet again, that this administration has little to no regard for the health and welfare of working people or any interest in protecting children from exposure to toxic chemicals,” Minovi said.
The proposal comes as the Trump administration’s broader policies toward chemical regulation have faced scrutiny from multiple directions. In recent months, critics have included not only progressive environmental groups but also activists aligned with the Republican-leaning “Make America Healthy Again” movement.
As the rule moves through the regulatory process, the debate underscores the difficult balance policymakers face: maintaining the supply of vital medical equipment while addressing legitimate concerns about toxic exposure in the communities that live closest to the facilities producing it.
