EPA Proposes Rolling Back Ethylene Oxide Emission Limits

The Trump administration's Environmental Protection Agency (EPA) proposed rolling back limits on ethylene oxide (EtO) emissions from medical sterilization facilities. The move aims to safeguard the supply of essential medical equipment by reversing stricter rules finalized in 2024 under the Biden administration.

According to latimes.com, the EPA claims that repealing the rules would save approximately $630 million for companies over 20 years. The agency argues that EtO emissions are an inevitable part of sterilizing medical equipment and that technology to meet the stricter standards does not readily exist.

Ethylene oxide is a colorless gas used to sterilize about half of all U.S. medical devices, including catheters, syringes, pacemakers, and surgical gowns. Long-term exposure has been linked to cancers such as leukemia and breast cancer, according to the Agency for Toxic Substances and Disease Registry.

The proposed rollback would give facilities a choice between installing continuous real-time monitoring systems or complying with modified pollution control requirements at sites emitting more than 10 tons of EtO annually. The EPA will hold a 45-day comment period after publishing the proposal in the federal register, with a final decision expected later this year.

Environmental and community groups have challenged the rollback, arguing that existing technology could meet the stricter standards without raising costs. The American Lung Association called the proposed rule change unacceptable, citing elevated cancer risks for people living near sterilization facilities. Environmental justice advocates also noted that many EtO facilities are located in minority communities.
