Sec. 2.
(a) No person shall emit or cause the emission of more than 90.7 megagrams (100 tons) per year of VOC from any source unless all VOC emitted from such source are reduced by at least eighty-five percent (85%) from emissions which would occur before the application of any control equipment or process. This section applies only to emissions of organic solvents which are VOC and which are liquids at standard conditions, and include diluents which are used as dissolvers, viscosity reducers, carrying agents, and cleaning agents. (1) The aggregate emissions of VOC into the atmosphere from any series of facilities designed for processing a continuously moving sheet, web, strip, or wire by a combination of operations shall comply with the requirements of this section.(2) Emissions of VOC into the atmosphere which result from the cleaning of any facility with organic solvents shall be included with the other emissions of VOC from such facility in determining compliance with this section.(3) Emissions of VOC into the atmosphere which result from the spontaneous drying of products after their removal from any facility shall be included with other emissions of VOC from such facility in determining compliance with this section.(b) The provisions of this section shall not apply to: (1) the manufacture of organic solvents;(2) the spraying or other employment of insecticides, pesticides, or herbicides;(3) industrial surface coating operations when the coating's solvent make-up does not contain highly reactive organic materials by volume greater than set forth in subdivision (b)(4) of this section.(4) The use of the following solvents:(A) hydrocarbons, alcohols, aldehydes, esters, ethers or ketones provided that the total of such solvents with olefinic or cyclo-olefinic unsaturation does not exceed five percent (5%) by volume either singly or in combinations;(B) aromatic organic solvents provided that the total of such solvents with eight (8) or more carbon atoms to the molecule, excluding ethyl benzene, does not exceed eight percent (8%) by volume either singly or in combinations;(C) ethyl benzene, ketones having branched hydrocarbon structures, trichloroethylene or toluene not exceeding twenty percent (20%) by volume either singly or in combinations;(D) any organic solvent or mixture of solvents which, because of its structure or composition, may be subject to the limitations of more than one (1) of the categories in clause (A), (B), or (C), above shall be considered a member of the class with the lowest percentage limitation. In no case shall a combination of compounds subject to the limitations of clause (A), (B), or (C) above, exceed twenty percent (20%) by volume of the combination;(E) saturated halogenated hydrocarbons, perchloroethylene, acetone, C(1)-C(5) n-paraffins, cyclohexanone, ethyl acetate, diethylamine, isobutyl acetate, isopropyl alcohol, methyl benzoate, 2-nitropropane, phenyl acetate, triethylamine, and non-photochemically reactive hydrocarbons.Air Pollution Control Board; 326 IAC 8-6-2; filed Mar 10, 1988, 1:20 pm: 11 IR 2546; readopted filed Jan 10, 2001, 3:20 p.m.: 24 IR 1477
