Emission Factor = [5.0E-03 lbs Cr/lb Cr]*[0.3 lbs Cr+6/lb Cr] = [1.5E-03 lbs Cr+6/lb Cr sprayed] This value is between the ARB HVOF emission factor for a control device with 90% efficiency and a control device with 99% efficiency, as summarized in Table C-3. Therefore, these results are reasonably consistent with ARB’s methods. Ohio
