The U.S. EPA definition is VOCs that have a vapor pressure < 0.1 mmHg at 20 C or a melting point > 20 C and does not sublime, if the vapor pressure is not known. EPA does not review or issue notices of exemption for products which meet the conditions for exemption. An official website of the United States government. The regulatory definition of VOC, including those compounds determined to have neglible photochemical reactivity,  has been pubished in the Code of Federal Regulations Part 51.100. Propylene Carbonate (also specifically exempted by EPA): Propylene Carbonate is exempted as a low reactivity compound by the EPA and also qualifies for the LVP-VOC exemption. PC is a less aggressive solvent in certain I&I applications, but it is highly miscible and can be used in customized blends (i.e. Federal Register references on that exemption are: 42 FR 35314 of … PC is a less aggressive solvent in certain I&I applications, but it is highly miscible and can be used in customized blends (i.e. CARB conducted further research to better understand impacts of LVP-VOCs emitted from the use of consumer products on ozone and secondary organic aerosol formation, and their environmental fate. The most recent list of VOC Exemptions are available here. Evidence shows that AMP is negligibly reactive in forming ground-level ozone. These determinations are made by regulation and are commonly referred to as VOC Exemptions. Update: U.S. EPA Exempt Volatile Organic Compounds PAINT -The U.S. Environmental Protection Agency (EPA) has determined that certain volatile organic compounds (VOC) have been determined to have negligible photochemical reactivity (40 CFR 51.100 (s)). The U.S. Environmental Protection Agency (EPA) has determined that certain volatile organic compounds (VOC) have been determined to have negligible photochemical reactivity ( 40 CFR 51.100 (s) ). She leads the VOC exemption program and related rule making for the revision of the EPA’s regulatory definition of VOC heading a workgroup of experts on HAPs among other toxic pollutants. Outdoors, VOCs are volatized or released into the air mostly during manufacture or use of everyday products and materials. There are thousands of individual chemical species of VOCs that can react to form ozone. March 27, 2014 - EPA added 2-Amino-2-methyl-1-propanol (also known as AMP, CAS124-68-5) to the list of compounds excluded from the regulatory definition of VOC. VOC Exemption Story In the U.S., a compound may be excluded as a VOC as a result of public petitions and new scientific data that demonstrate its negligible effect on the formation of ground-level ozone. EPA’s Safer Choice Criteria for VOC -exempt Solvents EPA’s Safer Choice Program will allow the use of certain solvents that do not fully comply with the Safer Choice Criteria for Solvents (at http://www2.epa.gov/saferchoice/standard) in specific circumstances. On October 17, 2011 and February 15, 2013, the U.S. EPA also proposed to add the following two compounds to the list of exclusions from their VOC definition:  2,3,3,3-tetrafluoropropene (HFO-1234yf)15 trans 1-chloro-3,3,3-trifluoroprop-1-ene (SolsticeTM1233zd(E))16 The U.S. EPA decision is still pending for these two compounds. : Propylene Carbonate is exempted as a low reactivity compound by the EPA and also qualifies for the LVP-VOC exemption. However, SCAQMD Rule 102 includes VOC-exempt products which may or may not be listed as VOC-exempt by the EPA. The two rules were published in the Federal Register on September 14th and 15th , 2020. This class currently includes acetone, dimethyl carbonate, methyl acetate, parachlorobenzotrifluoride (Oxsol 100), tert … Volatile Organic Compounds (VOC's) react with nitrogen oxides on hot summer days to form ozone (smog). The EPA lists compounds that it has determined to be negligibly reactive in its regulations as being excluded from the regulatory definition of VOCs (40 CFR 51.100 (s)), i.e., these are considered to make a negligible contribution to ground-level ozone formation. cyclic, branched, or linear, completely fluorinated alkanes; cyclic, branched, or linear, completely fluorinated ethers with no unsaturations; cyclic, branched, or linear, completely fluorinated tertiary amines with no unsaturations; and, sulfur containing perfluorocarbons with no unsaturations and with sulfur bonds only to carbon and fluorine, https://www.govinfo.gov/content/pkg/FR-1994-10-05/pdf/FR-1994-10-05.pdf#page=25, cyclic, branched, or linear completely methylated siloxanes, https://www.govinfo.gov/content/pkg/FR-1995-06-16/pdf/95-14804.pdf#page=1, https://www.govinfo.gov/content/pkg/FR-1996-02-07/pdf/96-2495.pdf#page=2, 3,3-dichloro-1,1,1,2,2-pentafluoropropane (HCFC-225ca), https://www.govinfo.gov/content/pkg/FR-1996-10-08/pdf/96-25787.pdf#page=1, 1,3-dichloro-1,1,2,2,3-pentafluoropropane (HCFC-225cb), 1,1,1,2,3,4,4,5,5,5-decafluoropentane (HFC-43-10mee), https://www.govinfo.gov/content/pkg/FR-1997-08-25/pdf/97-22510.pdf#page=1, 1,1,1,3,3,3-hexafluoropropane (HFC-236fa), 1,2-dichloro-1,1,2-trifluoroethane (HCFC-123a), 1,1,1,2,2,3,3,4,4-nonafluoro-4-methoxy-butane (C4F9OCH3), 2-(difluoromethoxymethyl)-1,1,1,2,3,3,3-heptafluoropropane ((CF3)2CFCF2OCH3), 1-ethoxy-1,1,2,2,3,3,4,4,4-nonafluorobutane (C4F9OCH2H5), 2-(ethoxydifluoromethyl)-1,1,1,2,3,3,3-heptafluoropropane ((CF3)2CFCF2OC2H5), https://www.govinfo.gov/content/pkg/FR-1998-04-09/pdf/98-9247.pdf#page=1, 1,1,1,2,2,3,3- heptafluoro-3-methoxy-propane (n-C3F7OCH3  or HFE-7000), https://www.govinfo.gov/content/pkg/FR-2004-11-29/pdf/04-26070.pdf#page=1, 3-ethoxy-1,1,1,2,3,4,4,5,5,6,6,6-dodecafluoro-2-(trifluoromethyl) hexane (HFE-7500), 1,1,1,2,3,3,3-hetafluoropropane (HFC-227ea), https://www.govinfo.gov/content/pkg/FR-2004-11-29/pdf/04-26069.pdf#page=1, 1,1,1,2,2,3,4,5,5,5-decafluoro-3-methoxy-4-trifluoromethyl-pentane (also known as HFE-7300), https://www.govinfo.gov/content/pkg/FR-2007-01-18/pdf/E7-638.pdf#page=1, https://www.govinfo.gov/content/pkg/FR-2009-01-21/pdf/E9-1150.pdf#page=1, trans-1,3,3,3-tetrafluoropropene (HFO-1234ze), https://www.govinfo.gov/content/pkg/FR-2012-06-22/pdf/2012-15347.pdf#page=1, https://www.govinfo.gov/content/pkg/FR-2013-02-12/pdf/2013-03057.pdf#page=1, HCF2OCF2OCF2CF2OCF2H (H-Galden 1040X, ZT 130, 150, or 180), trans-1-chloro-3,3,3-trifluoroprop-1-ene (SolsticeTM 1233zd(E)), https://www.govinfo.gov/content/pkg/FR-2013-08-28/pdf/2013-21014.pdf#page=1, 2,3,3,3-tetrafluoropropene   (HFO-1234yf), https://www.govinfo.gov/content/pkg/FR-2013-10-22/pdf/2013-23783.pdf#page=1, https://www.govinfo.gov/content/pkg/FR-2014-03-27/pdf/2014-06790.pdf#page=1, https://www.govinfo.gov/content/pkg/FR-2016-02-25/pdf/2016-04072.pdf#page=1, 1,1,2,2-Tetrafluoro-1-(2,2,2-trifluoroethoxy) ethane (HFE-347pcf2), https://www.govinfo.gov/content/pkg/FR-2016-08-01/pdf/2016-17790.pdf#page=1, 1,1,1,4,4,4-hexafluorobut-2-ene (HFO-1336mzz-Z), https://www.govinfo.gov/content/pkg/FR-2018-11-28/pdf/2018-25891.pdf#page=1.

This action will allow states to remove regulatory controls on AMP that are part of State Implementation Plans designed to help meet the ground-level ozone standards. These determinations are made by regulation and are commonly referred to as VOC Exemptions. Complete list of VOC Exemption Rules Jump to main content An official website of the United States government. Volatile Organic Compounds (VOC's) react with nitrogen oxides on hot summer days to form ozone (smog). EPA defines a VOC as “any compound of carbon, excluding carbon monoxide, carbon dioxide, carbonic acid, metallic carbides or carbonates, and ammonium carbonate, which participates in atmospheric photochemical reactions,” with the exception of chemicals that EPA has determined to have “negligible photochemical reactivity,” such as 2-amino-2-methyl-1-propanol. Some VOCs react slowly and changes in their emissions have limited effects on local or regional ozone pollution episodes. Those VOCs, determined to have low photochemical reactivity by approved test methods, may be excluded as VOC for regulatory purposes. To view more metadata about Sale or distribution of a pesticide product meeting all the criteria m 40 CFR 152.25(g) without a federal registeation is not a violation of FIFRA. Organic chemical compounds1 are everywhere in both indoor and outdoor environments because they have become essential ingredients in many products and materials. 2. It has been the EPA’s policy that organic compounds with a negligible level of reactivity should be excluded from the regulatory VOC definition so as to focus VOC control efforts on compounds that do significantly increase ozone concentrations. Ozone Volatile Organic Compounds (VOC) Exemptions Fact Sheets This page contains fact sheets on EPA rulings removing certain chemical compounds from being regulation as volatile organic compounds (VOC) under the Clean Air Act. On August 13, 2020, EPA released its final rules rolling back standards to control methane and VOC emissions from new oil and gas facilities. United States Environmental Protection Agency. The EPA has also determined that exemption of HFO-1336mzz-Z from the regulatory definition of VOC will not result in an increase of risk to human health and the environment, and, to the extent that use of this compound does … As such, these compounds do not have to be counted toward the VOC content of coatings products. Ground Level Ozone. U.S. EPA grants AMP VOC-exempt status In 2015, the United States Environmental Protection Agency (EPA) revised its regulatory definition to remove AMP from being regulated as a VOC, allowing the product to support an environmentally conscious domestic market. Federal Register references on that exemption are: Federal Register references on that exemption are: 42 FR 35314 of July 8, 1977 The definition for volatile organic compounds (VOC) comes from the Order adding toxic substances to Schedule 1 to the Canadian Environmental Protection Act, 1999, section 1, published in the Canada Gazette, Part II, July 2, 2003 and its amendment published June 3, 2016.
