The PM10 emission factors presented below are based on stepwise linear regressions of field emission test results of vehicles traveling over unpaved surfaces. Due to a limited amount of information available for PM2.5, the expression for that particle size range has been scaled against the PM10 results.

AP-42: Compilation of Air Emission Factors | Air Emissions
Compilation of Air Pollutant Emission Factors (AP-42) A source category is a specific industry sector or group of similar emitting sources. The emission factors have been developed and compiled from source test data, material balance studies, and engineering estimates. The Fifth Edition of
Total dust emissions from aggregate storage piles result from several distinct source activities within the storage cycle: 1. Loading of aggregate onto storage piles (batch or continuous drop operations). 2. Equipment traffic in storage area. 3. Wind erosion of pile surfaces and ground areas around piles. 4. Loadout of aggregate for shipment or for return to the process stream (batch or continuous...Chat Now
Environmental Impacts of Sand and Gravel Operations in
aggregate, stone, and industrial mineral mining for relatively small areas. The most recognized health hazards from these mines involve airborne particulate emissions. Total Suspended Particulates (TSPs) is a measure of all particulates emitted by a mine, while PM-10 particles represent some of the smallest particles (<10 µ in diameter) that can
The results obtained show that transport on unpaved roads is the mining activity that generates most of the emissions and that the total emissions may be reduced up to ...Chat Now

With regards to emission controls for PM 10 emissions (particulate matter with an equivalent aerodynamic diameter of 10 micrometres or less ie. 10µm), in the absence of measured data, or knowledge of the collection efficiency for a particular piece of equipment, an efficiency of 90% should be used in the emission factor equation to calculate
the PM and PM10 emissions for the additional pieces of equipment. Each emission factor was established and attached to a Source Classification Code (SCC). The SCC is used by the DNR computer database to assign emission factors to a certain piece of equipment and ...Chat Now

Dust emission is the key component of mine site dust management. Due to the fugitive nature of mine dust and fume emissions, it is difficult to conduct in-field measurements to quantify the emissions. Therefore, site-specific mining emissions are often unavailable. NPI and AP-42 emission factors are commonly used to estimate dust emissions at mines....Chat Now
