EPA Proposes Rollback of Ethylene Oxide Emission Limits

Overview of the Proposed Rule Change
On March 13, 2026, the Environmental Protection Agency (EPA) announced a proposal to weaken air pollution limits on ethylene oxide (EtO), a carcinogenic gas used in the sterilization of medical devices. This move aims to reverse stricter regulations established under the Biden administration, which sought to significantly reduce EtO emissions from approximately 90 commercial sterilization facilities across the United States. The EPA argues that the previous standards threaten the supply chain for essential medical equipment and could impose excessive costs on manufacturers.
Health Risks and Community Impact
Ethylene oxide is crucial for sterilizing about half of all medical devices, including pacemakers and surgical instruments. However, long-term exposure to EtO has been linked to increased risks of breast cancer, lymphoma, and other serious health issues among workers and residents near sterilization facilities. The EPA first classified EtO as a human carcinogen in 2016, and a 2022 study indicated that many facilities posed unacceptable cancer risks to surrounding communities, particularly in low-income and minority neighborhoods.
Justifications for the Rollback
EPA Administrator Lee Zeldin stated that the proposed rule reflects the agency's commitment to maintaining a stable domestic supply chain for medical devices while protecting public health. The agency claims that the stricter Biden-era regulations are burdensome and that the technology to meet these standards is not readily available. The proposed changes would allow facilities to choose between installing continuous monitoring systems or complying with modified pollution control requirements, potentially saving the industry an estimated $630 million over 20 years.
Criticism and Opposition
Environmental justice advocates and health organizations have criticized the proposed rollback, arguing that it prioritizes industry interests over community health. Laura Kate Bender, vice president of the American Lung Association, described the proposal as "unacceptable," emphasizing the dangers of both short-term and long-term exposure to EtO. Additionally, Darya Minovi from the Union of Concerned Scientists labeled the decision as "reckless," asserting that it disregards the health of vulnerable populations living near sterilization plants.
Official Statements and Responses
The EPA maintains that the proposed rule is necessary to ensure the availability of life-saving medical devices. Zeldin remarked, “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.” Conversely, critics argue that the rollback could exacerbate health risks for millions living near these facilities.
What's Next
The EPA's proposal will undergo a 45-day public comment period following its publication in the Federal Register. A final decision is expected later this year. Environmental groups, including the Southern Environmental Law Center and the Natural Resources Defense Council, have indicated plans to challenge the proposed rule in court, arguing that it undermines public health protections established under the previous administration.
Conflicting Reports & Gaps
While the EPA asserts that the previous regulations were illegal under the Clean Air Act due to multiple risk reviews, critics argue that the Biden administration's standards were based on new scientific findings that demonstrated the heightened carcinogenic risks of EtO. The debate continues over the balance between industrial flexibility and community health protections.
