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 are based on AP-42 Chapter 13.2.4.

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.

The revised AP-42 Emission Factors for Crushed Stone Processing should, therefore, be viewed in this context as a last resort method of estimating pollutants attributable to crushed stone processing. Many of the revisions to the PM 10 and PM 2.5 emission factors are generated from mathematical extrapolation methods. With one exception, there is no
