  2. Hazardous Air Pollutants: Ethylene Oxide

Queensbury, NY (Sterigenics US LLC - Kingsbury)

Sterigenics is located at 84 Park Road in Kingsbury, NY.  The facility opened in 1994 and uses ethylene oxide (Et0) to sterilize medical devices.

NOTE: On March 14, 2024, EPA announced final amendments to the National Emission Standards for Hazardous Air Pollutants (NESHAP) for Ethylene Oxide Commercial Sterilizers. This rule is one of the most important measures EPA is taking to reduce emissions of ethylene oxide and will significantly reduce lifetime cancer risks for people living near commercial sterilization facilities. It will reduce EtO emissions from commercial sterilization facilities to the outdoor air by 90 percent and, once implemented, will reduce the lifetime cancer risk for people living near all commercial sterilization facilities to levels below the Clean Air Act threshold for elevated risk. No individual will be exposed to EtO at levels that correspond to a lifetime cancer risk of greater than 100-in-1 million, and the number of people with a potential risk of greater than or equal to 1-in-1 million will be reduced by approximately 92 percent.

What EPA is Doing to Address Ethylene Oxide

In March 2024, the U.S. Environmental Protection Agency (EPA) strengthened Clean Air Act (CAA) standards for ethylene oxide (EtO) emissions from commercial sterilization facilities. To protect the public and the environment, EPA creates and enforces the rules according to a variety of environmental laws and regulations. The Federal Clean Air Act (CAA) regulates toxic substances in the air and EtO is classified as a toxic substance in the air.
