Air Quality: Revision to the Regulatory Definition of Volatile Organic Compounds--Exclusion of cis-1,1,1,4,4,4-hexafluorobut-2-ene (HFO-1336mzz-Z) (8 page(s), in English)

The Environmental Protection Agency (EPA) is proposing to revise the regulatory definition of volatile organic compounds (VOC) under the Clean Air Act (CAA). This action proposes to add cis- 1,1,1,4,4,4-hexafluorobut-2-ene (also known as HFO-1336mzz-Z; CAS number 692-49-9) 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.
