Revision to the Regulatory Definition of Volatile Organic Compounds--Exclusion of cis-1,1,1,4,4,4-hexafluorobut-2-ene(HFO-1336mzz-Z) (Final)
Nov. 28, 2018
The EPA is taking final action to revise the regulatory definition of volatile organic compounds (VOC) under the Clean Air Act (CAA). This final action adds HFO-1336mzz-Z to the list of compounds excluded from the regulatory definition of VOC on the basis that this compound makes a negligible contribution to tropospheric ozone (O3) formation.
