## Abstract

Under the Clean Air Act (CAA), the Environmental Protection Agency (EPA) is approving a state submission as a revision to the Illinois State Implementation Plan (SIP). The revision amends the Illinois Administrative Code (IAC) by updating the definition of volatile organic material (VOM), otherwise known as volatile organic compounds (VOC), to exclude 2-amino-2-methyl-1-propanol (AMP). This revision is in response to an EPA rulemaking in 2014 which exempted this compound from the Federal definition of VOC on the basis that the compound makes a negligible contribution to tropospheric ozone formation.
