| 2018-25891 | 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) | Rule | On May 1, 2018, the U.S. Environmental Protection Agency (EPA) published a proposed rule seeking comments in response to a petition requesting the revision of the EPA's regulatory definition of volatile organic compounds (VOC) to exempt cis-1,1,1,4,4,4-hexafluorobut-2-ene (also known as HFO-1336mzz-Z; CAS number 692-49-9). The EPA is now taking final action to revise the regulatory definition of 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. | 2018-11-28 | 2018 | 11 | https://www.federalregister.gov/documents/2018/11/28/2018-25891/air-quality-revision-to-the-regulatory-definition-of-volatile-organic-compounds-exclusion-of | https://www.govinfo.gov/content/pkg/FR-2018-11-28/pdf/2018-25891.pdf | Environmental Protection Agency | 145 | On May 1, 2018, the U.S. Environmental Protection Agency (EPA) published a proposed rule seeking comments in response to a petition requesting the revision of the EPA's regulatory definition of volatile organic compounds (VOC) to exempt... |
