No person shall operate any dry cleaning establishment using petroleum solvents other than non-photochemically reactive solvents without reducing solvent emissions by at least 90%. For purposes of this subsection, a photochemically reactive solvent shall be any solvent with an aggregate of more than 20% of its total volume composed of the chemical compounds classified in subsections (B)(1) through (3), or which exceeds any of the following percentage composition limitations, referred to the total volume of solvent:1. A combination of the following types of compounds having an olefinic or cyclo-olefinic type of unsaturation -- hydrocarbons, alcohols, aldehydes, esters, ethers, or ketones: 5%.2. A combination of aromatic compounds with 8 or more carbon atoms to the molecule except ethylbenzene: 8%.3. A combination of ethylbenzene, ketones having branched hydrocarbon structures, trichlorethylene or toluene: 20%.C. Where a stack, vent or other outlet is at such a level that fumes, gas mist, odor, smoke, vapor or any combination thereof constituting air pollution is discharged to adjoining property, the Director may require the installation of abatement equipment or the alteration of such stack, vent, or other outlet by the owner or operator thereof to a degree that will adequately dilute, reduce or eliminate the discharge of air pollution to the adjoining property.Ariz.
