§2.05 APPLICATION FOR PERMIT FOR SURFACE OR UNDERGROUND MINING <br />ACTIVITIES -- MINIMUM REQUIREMENTS FOR OPERATION AND RECLAMATION <br />PLANS. <br />The most effective method of coal handling from the standpoint of air <br />pollution is to keep the coal from ever being exposed to the outside <br />atmosphere. At the Bowie No. 2 Mine, the coal will be mined, crushed, <br />screened, transported by truck, stored and loaded into train cars, all <br />under the most current, best available technology in air quality <br />assurance. At each transfer point in the mining, crushing, and <br />screening process, the coal may be sprayed with a water solution to <br />minimize dust. <br />Throughout the silo and loadout area, all transfer points have bag <br />house controls for fugitive dust. On the mine site, all roads which <br />receive heaviest traffic are paved so as to reduce fugitive dust. Gravel <br />roads are watered as necessary to reduce fugitive dust emissions. A <br />magnesium chloride solution is also applied, as necessary, to gravel <br />roads to suppress dust. <br />• In the train loading operation, coal falls from a chute lowered in the car. <br />This is done to protect the flow of coal from wind flow while loading, <br />which decreases dust emissions. Coal cars are evenly loaded, so little <br />coal protrudes above the edge of the car into the slip-stream of air, <br />thereby reducing airborne coal dust particulates. Also, the quick <br />opening and closing of the knife gates at the train loadout creates an <br />intact columnar coal flow which results in less fugitive coal dust. <br />During warm months, the top of each train car of coal is sprayed with a <br />crusting agent before the train leaves the loadout facility. This <br />procedure is not required in the winter, when the coal freezes creating <br />its own crust. <br />Dust suppression during construction by watering is estimated to <br />reduce fugitive dust emissions by at least fifty percent. Chemical <br />stabilization, grading, mulching and revegetation practices were and will <br />continue to be instituted the first fall after completion of construction <br />both at the mine and at the silo area. This is discussed in detail in the <br />Reclamation Section 2.05.4. <br />TR-020 2.05 - 33 3/01 <br />
