My process generates a particulate dust that is on the list of regulated toxic air pollutants (RTAPs). Do I base my Env-A 1400 compliance determination on the total amount of dust emitted?
In most cases, only the “respirable” fraction of particulate RTAP emissions should be considered. Generally, “respirable” particulates will be considered to be that fraction of particles with a median aerodynamic diameter of less than ten microns (PM-10). If your RTAP emissions include particulate dusts, please consult with DES to confirm that only the respirable RTAP fraction requires consideration, and to determine what portion of emitted dusts are considered respirable.
