Handling and Storage <br /> L Fugitive particulate matter emissions are expected from the handling and storage of raw materials <br /> from quarry processing. The methodology for the calculation of particulate emissions from the <br /> handling and storage of raw materials is described in AP-42 Section 13.2.4 for aggregate handling <br /> ` and storage piles. The quantity of dust emissions from aggregate handling and storage operations <br /> varies with the volume of aggregate passing through the storage cycle. The emission factor for <br /> the quantity of emissions per quantity of material is estimated using the following equation: <br /> U 113 <br /> EF =k(0.0032) 5 J <br /> 111.4 <br /> C� <br /> 6. <br /> J <br /> where: <br /> EF = emission factor(lb emissions/ton material) <br /> k = particulate size multiplier(PM10=0.35) <br /> 6' U = mean wind speed(7.4 mph) <br /> M = material moisture content(0.7 %) <br /> 6. Based on available data, the emission factor for handling and storage activities is 0.0052 pounds <br /> of PM10 per ton of material processed(uncontrolled) and 0.0013 pounds of PM 10 per ton of <br /> L material processed(controlled). Weather data(wind speed)from <br /> http://www.wrcc.dri.edu/summary for Stockton, California. To account for emission controls, <br /> a control efficiency of 75%was applied. <br /> Wind Erosion <br /> In addition to emissions from the handling of storage piles, EPA provides a methodology for <br /> calculating emissions from wind erosion of storage piles as documented in AP-42 Section 13.2.5. <br /> The emission factor for wind-generated particulate emissions is dependent on the frequency of <br /> tr <br /> 9 <br /> L <br />
