EPA Continues to Defend Controversial IRIS Value for Ethylene Oxide Emissions

The U.S. Environmental Protection Agency (EPA) is under intense pressure to regulate ethylene oxide (EO) and reduce emissions based on its prior characterization of the substance as a likely cause of cancer. However, the inputs into that description have been challenged as flawed and just plain wrong. In spite of this, the EPA continues to press forward, ignoring strong scientific data and arguments in the name of environmental justice.
