The Department of Environmental Quality adopted amendments to La. Admin. Code tit. 33:III, §2117, Exemption of Volatile Organic Compounds. This rule adds the compounds propylene carbonate; dimethyl carbonate; and 1,1,1,2,2,3,4,5,5,5-decafluoro-3- methoxy-4-trifluoromethyl-pentane to the list of compounds that are exempt from the control requirement of La. Admin. Code tit. 33:III.Chapter 21. These compounds are added on the basis that they make a negligible contribution to tropospheric ozone formation. In addition to the added compounds, several chemical names are added for clarity. http://www.doa.la.gov/osr/reg/0905/0905.pdf p. 924.
