    The AP42 PM 10 equation for unpaved PM 10 emission rates, however, over predicts the emission rates of this haul road by approximately a factor of approximately 170 on a mass basis for haul trucks. Based on the Expedition's measured emission rate on paved roads indied that the emissions from this haul road are consistent with a paved road.
