Direct Final Rule to Revise Definition of Volatile Organic Compound Requirements for HFE-347pcf2

July 20, 2016 - EPA issued direct final revisions to the regulatory definition of volatile organic compounds (VOC) under the Clean Air Act.   This action adds 1,1,2,2-Tetrafluoro-1-(2,2,2-trifluoroethoxy) ethane (also known as HFE-347pcf2; CAS number 406-78-0) to the list of compounds excluded from the regulatory definition of VOC because it makes a negligible contribution to ground-level ozone formation.  Learn More

February 5, 2015 - EPA proposed to remove remaining Clean Air Act volatile organic compound (VOC) requirements for t-Butyl Acetate (TBAC). Learn More

Rule to Exlude 2-Amino-2-Methyl-1-Propanol from Control as a Volatile Organic Compound

March 27, 2014 - EPA issued a direct final rule with a parallel proposal identifying 2-Amino-2-methyl-1-propanol (also known as AMP) as a chemical compound that will no longer be regulated as a VOC under the Clean Air Act. This will remove AMP from regulatory requirements related to controlling VOC emissions in order to meet the national ambient air quality standards (NAAQS) for ozone. Learn More

Group of Four Hydrofluoropolyethers (HFPEs) No Longer Regulated as a Volatile Organic Compound

February 12, 2013 - EPA issued a final rule that excludes of a group of four Hydrofluoropolyethers (HFPEs) from regulation as a VOC under the Clean Air Act. This will remove the HFPEs from the control requirements in order to meet the ozone NAAQS. Learn More

2,3,3,3-tetrafluoropropene No Longer Regulated as a Volatile Organic Compound

October 22, 2013 - The Environmental Protection Agency has issued a final rule that identified 2,3,3,3-tetrafluoropropene (also known as HFO-1234yf) as a chemical compound that will no longer be regulated as a VOC under the Clean Air Act. This will remove it from regulatory requirements related to controlling VOC emissions in order to meet the ozone NAAQS. EPA will add HFO-1234yf to the list of negligibly reactive compounds in EPA’s regulatory definition of VOC. Learn More
