1.       ABSTRACT      Performance standards for controlling VOC emissions in the air, as well as solvent management and waste disposal in paint operations. For air VOC emission streams frequently associated with standard painting systems, performance parameters are provided.VOCs (volatile organic compounds) are released into the work environment and atmosphere during the vehicle painting process from paint solvents/thinners and paints. The majority of VOC pollutants are produced during the cleaning (purge flushing) and spraying processes of solvent-based paints, as the spray booth air gathers up all gaseous solvent compounds and overspray paint paints. Chemical aromatic and aliphatic esters hydrocarbons, glycolethers, alcohols, and ketones are among the VOCs.   الملخص
