On March 13, the EPA removed several pages about the risks of ethylene oxide, a known carcinogen and highly potent hazardous air pollutant used to sterilize medical supplies. The removed pages included information on ethylene oxide’s risks to humans and the environment, impacts of facilities on surrounding communities, webinars and resources for the public, and actions that the EPA and communities can take to reduce risk. While almost all of these pages now return “page not found” errors, the homepage for “Hazardous Air Pollutants: Ethylene Oxide” now redirects to a new homepage for ethylene oxide. This new page is devoid of information about the harms and risks and instead simply states the utility of ethylene oxide to sterilizing medical equipment and links to EPA’s new proposed rule to weaken regulation of the chemical.
