The Environmental Protection Agency (EPA) has proposed updates to the National Emission Standards for Hazardous Air Pollutants Clean Air Act for emissions of ethylene oxide (EtO) from commercial sterilizing facilities. The updated restrictions are estimated to reduce emissions of EtO by 80%, or 19 tons per year. Such a decrease would result in reducing the maximum individual cancer risk for a resident near a facility due to emissions from each of the commercial sterilizers from 6,000 in 1 million to 100 in 1 million or lower at an annual cost of $68 million. Once finalized, these standards would take effect in 18 months which is sure to be challenging.
