6. Truck Dump <br />The truck dump accepted coal from belly dump haul <br />trucks. The dump was enclosed by a 25 foot wide by <br />60 foot long by 30 foot tall building. Loaded trucks <br />approached the dump from the north and positioned <br />themselves over the dump, inside the building before <br />discharging their load of coal through the bottom of <br />their dump beds into a hopper below the building. Both <br />noise and dust created by the discharge of coal at the <br />truck dump was controlled by the building enclosure <br />and the use of a bag house to collect fugitive dust <br />originated by the transfer of coal, both from the truck to <br />the hopper and from the hopper to the elevating <br />conveyor which delivered coal to the silos. Both paved <br />and gravel surfaced roadways at the entrance and exit <br />(v� of the truck dump were frequently watered to allay <br />roadway dust. This truck dump operated under the <br />limitations of the Colorado Department of Health and <br />Environment Construction Permit 11 DL252-6. <br />Reclamation Status: The truck dump building and bag <br />house have been removed from site. Reclamation <br />activities occurred in 2007. Concrete foundations are <br />still in place. <br />7. Silo Elevating Conveyor (R-1) <br />A 600 foot 48 inch conveyor carried coal from the truck <br />dump to the top of the silos. The elevating conveyor <br />rested on bent construction, was covered and was <br />loaded by a vibratory feeder. The electrically driven <br />belt was powered at the ground level with a gravity <br />tensioning system located at ground level near the <br />drive system. <br />RN -07 2.05-8 02118 <br />
