President Donald Trump is temporarily exempting medical sterilization facilities that use the colorless gas ethylene oxide from tighter emissions standards, including plants in Georgia that have generated health concerns for residents living nearby.

Last year, then President Joe Biden’s administration finalized new emissions limits for plants that use ethylene oxide, also known as EtO.

The rules require facilities install new controls to limit releases of the gas, monitor continuously for leaks and meet other requirements. The standards were set to phase in starting in 2026, with the largest EtO users given an extra year to comply. Under Biden, the Environmental Protection Agency said the stiffer regulations would reduce emissions from EtO facilities by 90% and protect residents living near them.

But in a Thursday proclamation, Trump said he would extend the deadline for a slew of facilities across the country to meet the requirements, claiming the technology is not “commercially viable” to meet the timelines. Now, sterilizers will have two more years to make upgrades.

Trump argued the current rules would “likely force existing sterilization facilities to close down, seriously disrupting the supply of medical equipment.”

“In short, the current compliance timeline would undermine our national security,” Trump’s proclamation says.

The extension applies to several Georgia facilities, including:

  • Becton Dickinson (BD) facilities in Covington and Madison
  • The Sterigenics plant in Cobb County
  • Kendall Patient Recovery near Augusta
  • Sterilization Services of Georgia’s facility 15 miles from downtown Atlanta.

EtO plays a critical role maintaining safety in medical and dental settings by killing dangerous bacteria that can’t be eliminated by other methods, like steam or radiation. About half the medical devices used in the United States — approximately 20 billion devices each year — are sterilized with EtO, according to the EPA. It is also used to kill potentially harmful microbes lurking in spices, dried vegetables, walnuts and other food products.

But the gas has been known for years to be dangerous to humans.

In 2016, the EPA reclassified ethylene oxide as a human carcinogen and the gas has been linked to breast, lymphoid, leukemia and other types of cancers. That same year, the EPA determined ethylene oxide is dangerous at much lower levels than previously thought.

Based on its new threshold, EPA air modeling flagged several census tracts in Georgia for potential elevated cancer risks from exposure to ethylene oxide in 2018. But neither the agency nor the state Environmental Protection Division alerted the public. A year later, media reports revealed the potential for increased cancer risk based on the modeling faced by residents in neighborhoods surrounding Sterigenics’ Cobb County plant.

The situation spawned a slew of lawsuits and in 2023, Sterigenics agreed to pay $35 million to settle dozens of claims people who alleged their exposure to EtO from the plant caused cancer and other injuries. Sterigenics did not immediately respond to a request for comment on Trump’s proclamation.

Hundreds of lawsuits are still pending in Georgia against BD, Sterigenics and KPR. In May, the first of those to reach trial resulted in a $20 million verdict for a retired Covington-area truck driver, Gary Walker, who claimed decades of exposure to EtO from BD and its predecessor, C.R. Bard, was to blame for his non-Hodgkin lymphoma.

Michael Geoffroy, an attorney who’s part of Walker’s legal team and involved in many other EtO cases, said the Trump administration’s move “is only going to make things worse.”

“Loosening rules or delaying implementation of safety standards that are there to keep communities safe and make it to where fewer people get sick with cancer is just a step in the wrong direction,” Geoffroy said.

In a statement, BD spokeswoman Fallon McLoughlin said the company is “committed to the safe and responsible operation of our medical sterilization facilities and has a long history of compliance with local, state and federal regulations related to EtO emissions.”

She added BD has already installed new emissions controls at many facilities and is committed to meeting the new standards. But, she said doing so could require new equipment that may not be available in time to meet the deadline.

“The recently announced exemption will ensure there is a more realistic time frame to comply with the new requirements,” McLoughlin said.

A representative for Sterilization Services declined to comment. KPR did not immediately respond to requests for comment.

Mindy Goldstein, director of the Turner Environmental Law Clinic at Emory University, said the federal Clean Air Act allows presidents to exempt certain facilities from compliance for up to two years. But to do so, they must prove that the technology to meet the requirement is not available and the extension serves a national security interest.

Trump used both rationales in his proclamation. But Goldstein said he included little evidence to support the claims, which could give opponents an opening to challenge the move.

The Trump administration, meanwhile, has already said it’s reevaluating the Biden-era EtO rules, but it’s unclear whether they’ll seek to change the standard. Trump’s EPA has already unwound much of his predecessors’ environmental legacy, announcing plans to reconsider drinking water standards for certain toxic “forever chemicals,” roll back limits on greenhouse gas emissions from power plants and much more.
