The paper discusses a joint EPA/USAF study, the objective of which was to evaluate the capability of cost effective degreaser control concepts that eliminate solvent methylchloroform emissions to the atmosphere while complying with industrial hygiene limits. The study represents the only known evaluation dedicated to addressing the industrial hygiene impact and pollution reduction capability of various pollution options simultaneously. Study results indicate that the use of degreaser lip vents can result in significant increases in degreaser emissions. The use of the lip vent can be avoided by the proper installation and use of a freeboard extension, a freeboard chiller, and combinations of the two options. The results indicate that the industrial hygiene safety requirement and pollution control criteria can be achieved without exceeding exposure limit levels by use of the freeboard chiller.
