Final Draft
EPA is separating the component of emissions due to exhaust, brakewear and tirewear from the composite fugitive dust emission factor equation in AP-42 for two reasons. The first reason is to eliminate the possibility of double counting emissions. EPA's Mobile6.2 model estimates PM emissions from exhaust, brakewear and tirewear.

EPA Reminder About Inappropriate Use of AP-42 …
Within AP-42, each emission factor is given a rating between "A" (excellent) and "E" (poor) (see Table 1 below). It is important to note that half of the emission factors are rated "D" or "E" and one-fifth are unrated. This means that less than one-third of the emission factors are rated between "Excellent" and "Average.".
