Abstract
EPA is approving a request submitted by the Illinois Environmental Protection Agency (Illinois EPA) on July 3, 2013, to revise the Illinois state implementation plan (SIP). The submission amends the Illinois Administrative Code (IAC) by updating the definition of "Volatile organic material (VOM) or Volatile organic compound (VOC)" to add trans-1,3,3,3-tetra-flouropropene (HFO-1234ze) to the list of compounds excluded from the definition of VOM or VOC. This revision is based on EPA's 2012 rulemaking which added HFO-1234ze to the list of chemical compounds that are excluded from the Federal definition of VOC because of their negligible contribution to the formation of tropospheric ozone.
