WebSometimes, HAP emission factors will give a number higher than a 'total' VOC or PM10 emission factor. In this case, you have to go with the number you believe is more accurate, and correct the other. For instance, if the particulate HAPs were higher than the PM10 above, you might either raise the PM10 number, or lower the individual HAPs.
