U.S. Chamber files coalition amicus brief urging D.C. Circuit to vacate Clean Air Act rule that regulates industrial chemicals, including ethylene oxide

January 24, 2025

The brief explains how the rule misreads CAA section 112(f), which authorizes EPA to perform a single risk-based review to set standards for each category of emissions sources and does not allow EPA to perform additional risk-based reviews.

Trevor S. Cox, Charles H. Knauss, and J. Pierce Lamberson of Hunton Andrew Kurth LLP served as outside counsel.
