Tertiary butyl Acetate. exempt solvent density is 11 pounds per gallon, and let: x = maximum pounds of VOC that can be added Then: x = 1.3 pounds VOC Since the VOC has density 7.2 pounds per gallon, this is equivalent to Finally, to make a full gallon of coating the formulator must still add: 1 - 0.25 - 0.18 = 1 - 0.43 = 0.57 gallon exempt solvent or 0.57 x 11 = 6.3 . The VOC Calculator (XLS, 90kb) is a spreadsheet that will calculate both VOC values based on the solids, water content and density of the material. Car exhaust, gasoline-powered lawn and garden equipment, gasoline dispensing stations, industrial coating operations, printing shops, paints, household chemicals - are some of the sources of VOC. %PDF-1.5

(198.69 KB), Exclusion of cis-1,1,1,4,4,4-hexafluorobut-2-ene (HFO-1336mzz-Z), - EPA added HFO-1336mzz-Z to the list of compounds excluded from the regulatory definition of volatile organic compounds or VOC. Cyclic, branched, or linear, completely methylated siloxanes (VMS) are not subject to this prohibition. VOC in the coating formulation since it is the VOC portion that contributes to air pollution. This class of solvent currently includes acetone, dimethyl carbonate, methyl acetate, parachlorobenzotrifluoride (Oxsol 100), tert-Butyl acetate, and propylene carbonate. Volatile Organic Compounds (VOC) react with nitrogen oxides on hot summer days to form ozone (smog).

Some VOC react slowly and changes in their emissions have limited effects on local or regional ozone pollution episodes.

Organic materials that do not appear on this appendix and are not classified as a VOC or an exempt VOC can be summed into the category "Grouped LVP" in the 2018 ART. Compounds that are more reactive than ethane continue to be considered reactive VOCs, and therefore are subject to air quality regulation.

HFO-1336mzz-Z is used in a variety of applications as a replacement for foam expansion or blowing agents. The United States Environmental Protection Agency (U.S. EPA) excludes certain organic compounds from the regulatory definition of a VOC based on the compound's negligible contribution to the formation of ground-level ozone, better known as smog. An official website of the United States government. pressure of any solvent that does not fully comply with the solvent criteria must be low enough to qualify as "volatile organic compound (VOC)-exempt" (under California Air Resources Board and EPA criteria*), and must be among the safest available solvents compared to similar alternatives. Some rules include prohibitions from using certain Group II Exempt Compounds as they have potential toxic health risks, as well as being contributors to upper-atmosphere ozone depletion and other potential environmental impacts. Inorganic Compound. [9] Due to its classification as VOC exempt, dimethyl carbonate has grown in popularity and applications as a replacement for methyl ethyl ketone (MEK) and other solvents.

Rule 102(PDF) - Definition of Terms contains a complete and updated list of exempt compounds. Smog is formed when VOCs photochemically react with oxides of nitrogen (NOx) in the atmosphere. (pdf) The policy of excluding negligibly reactive compounds from the regulatory definition of VOC was first laid out in the Recommended Policy on Control of Volatile Organic Compounds (42 FR 35314, July 8, 1977) and was supplemented subsequently with the Interim Guidance on Control of Volatile Organic Compounds in Ozone State Implementation Plans. Exemption of a compound from the EPAs VOC definition in 40 CFR 51.100(s) does not exempt it from other regulation,such asdue to its toxicity, greenhouse gas formation potential or other properties.
