Coal from the underground mines will be stockpiled at the <br />portals, and then loaded into the haul trucks using 15 cubic yard front end loaders. <br />Emission Factor and Controls <br />The emission factor for loading coal is: (0.5*1.16)/(M" 1.2) lb/ton (AP~2, Table 8.24-2, dated <br />9/88). No controls are practicable. <br />where: <br />M =material moisture content = 2.7% <br />Annual Emissions <br />Total emissions from loading 2,418,000 tons of coal from all lorencito Canyon Mine facilities <br />will be 182.69 tons per year. <br />Surface Mining <br />• The moisture content of coal from surface mining will be 2.7% (Lorencito Canyon Mine Permit <br />Application submitted to Division of Minerals and Geology, Colorado Department of Natural <br /> <br />
