EPA Finalized Standards to Reduce Emissions of Carcinogen Ethylene Oxide from Commercial Sterilizers

EPA finalized new standards to emissions of ethylene oxide (EtO), a human carcinogen, from chemical sterilizers. EPA estimated the new standards would lower EtO emissions from commercial sterilizers by 90%. In addition to setting more stringent EtO emissions standards, the rule increases accountability and transparency by requiring continuous emissions monitoring and quarterly reporting for most commercial sterilizers. EPA estimated that reducing EtO exposure will help alleviate cancer risk for workers and nearby communities. Of the 88 covered facilities, EPA found many are located near residences, schools, and other public facilities, and 23 pose high lifetime cancer risks to surrounding communities, including several facilities in Puerto Rico.
