Detailed Emission Factor Search. Source Classification Codes should be entered without dashes. Description levels 1 through 4 should be selected in order. Be careful about limiting your search too much with descriptions, control codes and pollutants. Keep your search criteria broad to begin with and narrow it as you review the results....

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.

Frequently Asked Questions. The factor is usually expressed as pounds per unit weight, volume, length, distance, time, etc. An example is a PM10 emission factor for a boiler expressed as pounds per unit of natural gas burned such as 2.5 lb of PM10/million cubic feet ...

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

Chapter 9. Dust emissions may be generated by wind erosion of open areas of exposed soils or other aggregate materials within an industrial facility. These sources typically are characterized by nonhomogeneous surfaces impregnated with nonerodible elements (particles larger than approximately 1 centimeter [cm] in diameter)....

The reporting threshold for estimating emissions of Total Particulate Matter (TPM), Particulate Matter less than or equal to 10 microns in diameter (PM 10) and Particulate Matter less than or equal to 2.5 microns in diameter (PM 2.5) from unpaved road surfaces is 10 000 Vehicle Kilometres Travelled (VKT)

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 ...

Energy and GHG Emissions Management The Mining

Energy and GHG Emissions Management Improving energy efficiency and reducing greenhouse gas (GHG) emissions are priorities for the Canadian mining industry as a way to limit impacts to the environment and to help reduce operational costs at the mine-site.

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....

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

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.
