The use of a mass balance approach is the easiest way to calculate VOC, HAP, and TAC emissions from a coating operation. This method uses coating formulation and usage data and assumes that all the VOC, HAP, and TAC contained in the liquid (volatile) portion of the coating is emitted into the air after the coating is applied and dried.
