"The Environmental Protection Agency (EPA) announced Monday [Dec. 27] that it will require more facilities to report the release of a carcinogenic gas called ethylene oxide (EtO), after previously not requiring them to do so.

The agency said in a statement Monday that it believes the 29 facilities facing the new requirement are “likely to exceed” the emissions reporting threshold of 10,000 pounds per year of EtO.

It argued that the move will help communities deal with the substance, which is mainly used to make other chemicals and for sterilization."
