For purposes of conducting air quality modeling, the emission rates of PM 10 from various crushed stone processing operations will be determined by applying the appropriate emission factor from Table 1 and Table 2 of this guidance. These emission factors have been extracted from EPA's AP-42 Section 11.19.2 as published in the most recent edition.
English units). Although no emission factors are presented for construction sand and gravel processing, emission factors for the crushing, screening, and handling and transfer operations associated with stone crushing can be found in Section 11.19.2, "Crushed Stone Processing." In the absence of other data, the emission factors presented in ...

accompanying an emission factor means that this factor is the weighted average ash content of the fuel burned, expressed as a percent. See, for example, SCC 1-01-008-01 on the facing page.
Wet and Dry Emission Factors for Crushed Stone Processing Operations. Incorporates emissions from transfer of material to the screen, but not transfer of material from the screen. …
The standardized PM10 emission factors specified above are based on the controlled and uncontrolled crushing values listed in Table 11.19.2- 2 of Section 11.19.2 of AP -42 (1/95). The TSP factor was derived using the ratio of particulate size multipliers in 13.2.4 of AP-42 (1/95) and the PM10 factors; TSP Factor = PM10 Factor x (0.74 / 0.35)

Particulate emission factor data for haul roads at sand and gravel facilities can be estimated using Eq. 1 for PMi0 and Eq. 2 for PM2.5. These equations have been derived based on tests at three stone crushing plants.19,20 E = (s/3)0,8(M/2)-0,9 (1) E = 0.25(s/3)°'8(M/2)-0'9 (2) Where E is the PM10 emissions from haul roads (lbs/VMT); s,

The PM1Q weight percent of the Known source's PM emissions is applied to the PM emission factor of the similar source to be characterized. No judgement of the accuracy of the PM1Q emission factors produced by this process is attempted. Sucn PM1Q emission factors are, however, considered to be approximately as accurate as default estimates.
