Section R18-2-727 - Standards of Performance for Spray Painting Operations

A. No person shall conduct any spray paint operation without minimizing organic solvent emissions. Such operations other than architectural coating and spot painting, shall be conducted in an enclosed area equipped with controls containing no less than 96% of the overspray.

B. No person shall either:

1. Employ, apply, evaporate or dry any architectural coating containing photochemically reactive solvents for industrial or commercial purposes; or

2. Thin or dilute any architectural coating with a photochemically reactive solvent.

C. For purposes of subsection (B), 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 (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%.

D. Whenever any organic solvent or any constituent of an organic solvent may be classified from its chemical structure into more than one of the groups or organic compounds described in subsection (C)(1) through (3), it shall be considered to be a member of the group having the least allowable percent of the total volume of solvents.
