Understanding the EPA's 2024 NESHAP Amendments

The U.S. Environmental Protection Agency (EPA) has introduced pivotal amendments to the National Emission Standards for Hazardous Air Pollutants (NESHAP) for Ethylene Oxide (EtO) Commercial Sterilization and Fumigation Operations.

These amendments represent a significant overhaul of current standards, aimed at reducing EtO emissions by 90%. Changes include enhanced pollution controls and a shift to advanced continuous source monitoring.

What this means for your facility:

Finalized on April 5, 2024, the EPA requires currently operating facilities two to three years to comply with updated regulations. New facilities must be in compliance upon start-up.

The EPA proposes two compliance options:

Option 1: EtO Continuous Emissions Monitoring System (CEMS), including optically enhanced FTIR

Option 2: Initial and annual performance tests combined with continuous perimeter monitoring

Spectrum's Turnkey EtO Monitoring Approach

Unlike conventional narrow-band focus methods, our full-spectrum scan technology offers a comprehensive view of your emission landscape, allowing us to quantify multiple compounds in a single scan.

Our optically enhanced WaveRunIR-EXT monitor continuously achieves low parts per billion levels from process and emission source applications. With this data, you can meet stringent EtO monitoring requirements while gaining insights into your entire sterilization process.

Full Process Monitoring
With Spectrum’s customizable devices and solutions, we quantify your compounds of concern in a single scan—whether targeting Ethylene Oxide, Carbon Dioxide, Aldehyde, or Propylene Oxide. Monitor your entire sterilization process to ensure maximum efficiency and compliance.
