Particulate matter emission factors are provided in Tables 11.24-1 and 11.24-2 for various metallic mineral process operations including primary, secondary, and tertiary crushing; dry grinding; drying; and material handling and transfer. Fugitive emissions are also possible from roads and open stockpiles, factors for which are in Section 13.2.

For unique emission sources, additional data must be ing the factor used in determin(EF or TP) before it can be used in emission calculation ed in the following notes: as discuss . Note 1: For mining/quarrying, emission factor is expressed in pound per blast (lbs. /blast) for TSP (Total Suspended Particulate) ≤ 30 µm and is calculated as:
