The U.S. Environmental Protection Agency has proposed a significant rollback of emission standards for ethylene oxide, a gas used to sterilize medical equipment, citing the need to lower industry costs and prevent supply shortages.
Regulatory Rollback
The proposal seeks to ease strict 2024 emission limits on ethylene oxide for approximately 90 commercial sterilization facilities.
Industry vs. Public Health
While the EPA aims to support the medical device industry, health advocates warn of increased cancer risks for workers and nearby residents.
Administrative Shift
Led by Administrator Lee Zeldin, the move reflects the Trump administration's broader strategy to relax environmental regulations to favor industrial growth.
The Environmental Protection Agency proposed on March 13, 2026, to ease emission limits on ethylene oxide, a carcinogenic gas used primarily to sterilize medical devices, reversing stricter standards set under the previous administration. The proposal affects approximately 90 commercial sterilization facilities across the United States. The move was issued under President Donald Trump and is part of a broader effort by his administration to relax pollution limits and reduce costs for industry, according to reporting by Reuters, Bloomberg, and The New York Times.
Ethylene oxide is used by commercial sterilization facilities to clean medical devices that cannot withstand heat or moisture-based sterilization methods. The gas has long been a subject of regulatory scrutiny because of its links to cancer in workers and residents living near facilities that emit it. The EPA's proposed rule would loosen the limits that govern how much of the gas these roughly 90 facilities are permitted to release into the surrounding air. The proposal represents a significant shift from the direction regulators had taken in recent years, when limits on the gas were tightened in response to public health concerns.
The EPA was established in December 1970 after President Richard Nixon signed an executive order creating the agency. Ethylene oxide has been regulated as a hazardous air pollutant for decades, with the agency periodically revising emission standards for facilities that use it. The 2024 tightening of ethylene oxide limits under the Biden administration drew strong opposition from the medical device industry, which argued the stricter rules threatened the supply of sterilized equipment. The Trump administration's current proposal follows a pattern of rolling back those stricter standards across multiple industrial sectors.
Lee Zeldin, who has served as EPA Administrator since January 2025, leads the agency that issued the proposal. The Trump administration has framed the rollback as a measure to lower costs for the medical device industry and the commercial sterilization sector. Critics and public health advocates have argued that loosening limits on a known carcinogen increases cancer risk for communities located near sterilization facilities. The proposal was described by The New York Times as the latest in a series of EPA actions under Trump to relax pollution controls and reduce the regulatory burden on industry.
