Ethylene Oxide Emissions Information for Residents

October 2022 Fact Sheet

Introduction

The U.S. Environmental Protection
Agency is reaching out to residents
surrounding commercial sterilizers that
release high levels of a chemical called
ethylene oxide (EtO) into the air causing
elevated cancer risk, including DeRoyal
Industries located at 1135 Hwy 33 South
in New Tazewell.

EtO is a colorless, odorless gas that is
often used for sterilization purposes.

Inhaling EtO at elevated levels over a
lifetime can increase a person's risk of
getting cancer. However, short-term
exposures to the concentrations found in
residential communities should not cause
acute (non-cancer) health issues, like
nausea, dizziness, or breathing problems.

EPA has determined that portions of New
Tazewell neighborhoods in the vicinity of
DeRoyal Industries have an estimated lifetime cancer risk at or above 100 in a million. A lifetime
cancer risk of 100 in a million means that, if 1 million people were exposed to this level of EtO in
the air 24 hours a day for 70 years, 100 people may develop cancer from continuous exposure.
The risk gradually increases as you get closer to the facility, reaching an estimated maximum of
3,000 in a million in areas closest to DeRoyal Industries.

EPA will soon propose a new rule to limit EtO emissions from commercial sterilizers and will seek
public input on the rule. In the meantime, the agency is working with DeRoyal Industries and
other sterilizers across the country on ways they can voluntarily control emissions to reduce risk.

EPA is sharing this information because communities have a right to know about emissions that
could affect their health and well-being. EPA will host two open houses and community meetings
in New Tazewell on October 25, 2022, to provide residents an opportunity to learn more and get
their questions answered. Residents can choose to participate in the community meetings in-
person or virtually. Please follow the instructions in the blue box above to register.

What is EtO?

EtO is a colorless, odorless gas, that is used at commercial sterilizers like DeRoyal
Industries to sterilize devices that cannot be sterilized using steam or radiation,
such as some medical and dental equipment. According to the Food and Drug
Administration, approximately 50 percent of sterile medical devices are treated
with EtO - about 20 billion devices each year. EtO is also used to sterilize some
food products such as spices, certain dried herbs, dried vegetables, sesame seeds

and walnuts.

EPA's Overall Action Plan

•	Review Clean Air Act regulations to further reduce EtO emissions from industrial facilities,
particularly rules to control air toxic emissions from commercial sterilizers and facilities that
manufacture chemicals.

•	Work with state and local air pollution control agencies to reduce EtO emissions.

•	Expand environmental reporting requirements for sterilization facilities.

•	Reevaluate how EtO is used within sterilization facilities with the goal of reducing risks to
workers who handle EtO and those who are exposed in other ways.

•	Provide financial resources and technical support for local monitoring activities.

Background

EPA has regulated EtO emissions for 30 years, however in 2016, new scientific information
revealed that EtO is more toxic than previously understood. This prompted EPA to conduct
nationwide analyses and intensive data collection, which has revealed that certain communities
near commercial sterilizers could have elevated cancer risks due to lifetime exposures to EtO.

Public Webinar (August 10, 2022), location-specific maps, information about individual
commercial sterilizers, and health risks for residents and workers.
