A substantial portion of these emissions consists of heavy particles that may settle out within the plant.
May 31, 2017 rock and the Tertiary Crushing Emission Factor is utilized as a conservative estimate because there is no Primary Crushing Emission Factor. Additionally, the use of AP-42 Chapter 11.19.2-2 Controlled Emission Factors is allowed as described in the BAPC AP-42 Chapter 11.19.2 Emission Factor Decision Tree. Finally, multipliers for PM 2.5

Primary Crushing emissions were assumed to be 25 % of Tertiary crushing emissions, based on particle surface area. Secondary Crushing emissions were assumed to be 50% of Tertiary Crushing Emissions, based on surface area. Primary Screening emissions were assumed to be 25% of Tertiary Screening emissions, based on particle surface area.

- The AWR / MPI / District Crushing Operation Emission Factors for this material are 0.00240 lbs PM10 and 0.00507 lbs TSP per t on of material processed. - The PM10 factor is based upon the uncontrolled PM10 tertiary crushing value in Section 11.19.2, Table 11.19.2-2 of AP-42 (1/9 5) and the District - AWR - MPI agreement dated 4/9/96.
Dec 06, 2011 Ecology. It is logical that emissions of PM aka TSP and PM10 would be greater when crushing smaller aggregate. Ecology could not verify this assumption, so we chose to be conservative and use the larger emission factors presented

Mar 01, 2019 Tertiary crushing generated two to three times as much PM 2.5 (130200 g/m 3) compared to secondary crushing (7080 g/m 3). The largest number of samples exceeding the measurement capacity was found in Quarry 6, where the number of crushing units was the highest (tertiary crushing with four crushing units).
