The Environmental Protection Agency (EPA) is proposing to approve a revision to the Illinois State Implementation Plan (SIP). The revision will amend the Illinois Administrative Code (IAC) by updating the definition of volatile organic material (VOM) and volatile organic compounds (VOC) to exclude (Z)-1,1,1,4,4,4-hexafluorobut-2-ene. This revision is consistent with an EPA rulemaking in 2018, which exempted this compound from the Federal definition of VOC on the basis that the compound makes a negligible contribution to tropospheric ozone formation.
The agency’s own summary, as published.
