The brief explains that in regulating ethylene oxide, EPA failed to follow its own guidance on science and modeling issues and did not provide a reasonable explanation for such deviations.

Elbert Lin, Matthew Z. Leopold, and Michael Dingman of Hunton Andrews Kurth LLP and the U.S. Chamber’s Litigation Center served as co-counsel for the U.S. Chamber.
