2014 NATA Uses Highly Flawed Ethylene Oxide Risk Value

WASHINGTON (September 25, 2018) – On August 22, 2018, the U.S. Environmental Protection Agency (EPA) released the results of its 2014 National Air Toxics Assessment (NATA). On September 20, 2018, the Ethylene Oxide Panel of the American Chemistry Council (ACC) submitted a Request for Correction under the Information Quality Act to ethylene oxide information used in the 2014 NATA. ACC represents producers and users of etylene oxide.

“We are concerned that EPA’s 2014 NATA uses a significantly flawed risk value for ethylene oxide (EO) that was generated by EPA’s Integrated Risk Information System (IRIS) program. The EO risk value is far below levels found in nature. In fact, it is 19,000 times lower than the normal, naturally-created levels of EO in the human body.

“ACC has filed a petition under the Information Quality Act seeking a correction to EO risk information in the NATA based on the IRIS risk value. Our petition outlines numerous problems with the methodology and substance of the EO IRIS risk value and presents reliable scientific evidence in support of correction. We offer as an alternative a range of risk values that is both scientifically sound and protective of public health for use in the NATA and any EPA regulatory actions.”
