The Crucial Role of Ethylene Oxide in Medical Device Sterilization
Ethylene oxide (EtO) continues to be a critical method for sterilizing medical devices. Its unique compatibility with a broad range of materials and ability to penetrate complex geometries ensures optimal sterility. At C.G. Laboratories, we remain committed to providing high-quality EtO sterilization services to our customers, even as we navigate a changing regulatory landscape.
Recent EPA Regulatory Changes
NESHAP Revisions
On April 5th, 2024, the Environmental Protection Agency (EPA) codified revisions to the National Emission Standard for Hazardous Air Pollutants (NESHAP) in 40 CFR Part 63, Subpart O. These revisions introduce several new restrictions on EtO sterilizers:
- Up to tenfold further reduction in EtO emissions
- Specific facility design requirements
- Installation of new, costly emission monitors
- Control of emissions in previously unregulated areas, including warehouses
- More extensive and frequent compliance reporting
Pending EPA Proposals
Additionally, the EPA’s Office of Pesticide Programs (OPP) is seeking public comment on a proposal that would further regulate EtO sterilizers. If enacted, this proposal would:
- Terminate EtO sterilization for most non-medical products, including cosmetics
- Limit EtO concentration during sterilization cycles to 500 mg/L (current industry average is 758 mg/L)
- Require a hundredfold reduction in on-site EtO levels compared to existing OSHA regulations
- Mandate further changes to facility infrastructure and layout
Impact on the Medical Device Industry
These new EPA regulations will have far-reaching effects on the medical device industry:
- Full validation of new parameters for existing sterilization cycles
- Mandatory FDA review of all sterilization cycles upon validation
- Longer cycle times, leading to decreased throughput and increased lead times
- Restriction of validated cycles to products of similar design only
- Reduction in sterilization capacity during equipment upgrades
We are concerned that these EPA restrictions could lead to a shortage of sterile medical devices in the U.S. supply chain, potentially affecting both manufacturers and patients.
