Zelienople, Pennsylvania (American Contract Systems Inc.)
American Contract Systems Inc. is located at 4050 Jacksons Pointe Court, Zelienople, PA. The facility uses ethylene oxide (EtO) to sterilize medical equipment and materials.
EPA scientists and analysts recently completed a risk assessment to understand the impact of EtO emissions from the American Contract Systems Inc. facility. As part of this risk assessment, we used the most recent available information about how much EtO the company emits into the air and we modeled estimated cancer risks to people living nearby. The risk assessment identified elevated cancer risk in the Zelienople community. EPA is committed to working with state and local agencies, facilities, and communities to reduce this risk.

This map shows EPA’s estimates of lifetime cancer risks from EtO near American Contract Systems Inc. in Zelienople, PA. As you can see from the map risk decreases with distance from the facility.
The area in blue shows estimated lifetime cancer risks of 100 in a million or greater from breathing air containing EtO emitted from the facility (or the same as 1 additional cancer case in 10,000 people). 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 would be expected to develop cancer from that exposure. EPA cannot predict whether an individual person will develop cancer.

For this risk assessment, we looked at excess cancer risk attributable to a single chemical, EtO. This estimated risk is in addition to the risk of developing cancer from other causes. This is a worst-case scenario that assumes a person stays in the highest risk area 24 hours a day continuously for 70 years. EPA takes this approach because we want to be protective of the most exposed and most vulnerable individuals from risk associated with EtO emissions from this facility.
Additional Details
American Contract Systems Inc. was founded in 2000. Its headquarters is in Minneapolis, Minnesota and currently employs staff in ten states. The Zelienople facility was founded in 2014 and has approximately 15 employees. The facility is a manufacturer of surgical and medical equipment with sterilization services. EtO is injected into sealed packages to sterilize equipment. American Contract Systems, Inc. estimates that it uses about 80 lbs. of EtO per month.
Pennsylvania Department of Environmental Protection is working with American Contract Systems Inc. to install controls.
What EPA is Doing to Address Ethylene Oxide
Now: EPA finalized regulations for Ethylene Oxide Commercial Sterilizers that will significantly lower risk in the community. EPA is working with the Commonwealth of Pennsylvania to reduce emissions at American Contract Systems, Inc. EPA has provided technical support to our air agency partners as part of this work. As part of our strategy to address EtO emissions from commercial sterilization facilities nationally, the Agency is reviewing controls on regulated equipment and processes that emit EtO to determine whether additional air pollution controls are needed. This review includes examining new developments in practices, processes and control technologies, considering cost and feasibility, as well as addressing any previously unregulated emission points.
