Mountain Coal Company, LLC <br />West Elk Mine <br />Proposed Product Coal Handling Facilities Additions <br />Scalping Station <br />The Scalping Station, expected to be approximately 20 feet wide by 40 feet long by 50 feet tall (20' longer <br />and 10' higher than the earlier proposed Transfer Tower), will house a single 8' wide by 24' long vibrating <br />screen to remove the oversize material and drop it into a concrete walled pit at ground level. Undersize ROM <br />coal material will be directed onto plant feed conveyor PR-2. <br />Product Conveyors and Storage Additions <br />Product conveyors P3 and P5 are 950 foot long, 36" wide conveyors that are constructed side-by-side within <br />a single truss structure from the Preparation Plant to new stacking tube ST-5. Product conveyor P-4 is a 200 <br />foot long, 48" wide conveyor designed to move plant product from conveyor P-3 to existing stacking tube <br />ST-4. P-4 can also be reversed to move material from existing product conveyor S-3 to ST-5. Product <br />conveyor P-5 is designed to discharge only to ST-5. The existing R-5 reclaim conveyor and tunnel will be <br />extended to a point east of ST-5 to provide for reclaim to the existing unit train loading conveyor. <br />Table of Proposed Conveyors <br />Conveyor Length (ft) Belt Width (in) Structure Width / Type Cover or Enclosure Type <br />P-3/P-5 950 36 14'/ Open Steel Truss '/ Hood Covers Each <br />P-4 200 48 10'/ Open Steel Truss 3/o Hood Cover <br />R-5 Ext. 250 72 84", Belt Structure Only Enclosed in Reclaim Tunnel <br />Table of Proposed Buildings and Structures <br />Item Length ft Width ft Height (ft) T e* <br />Stack Tube #5 (ST-5) P Thick Wall 12 (Diameter) 109 RCT <br />ST-5 Head House 20 14 40 SS <br />Scalping Station 40 (added 20) 20 (same) 50 (added 10) SS <br />* Structure Types: <br />RCT - Reinforced Cylindrical Concrete Tower <br />SS - Structural Steel with No Siding or Enclosure <br />Table of Proposed Reinforced Concrete Floors, Footings and Other Structures <br />Item Length (ft) Width (ft) Thickness ft <br />Scalping Station/Transfer Tower Foundation 40 (added <br />20) 20 <br />(same) 1 <br />Conveyors P-3/P-5 Bent Foundations (3 total - size each) 15 2 4 <br />Conveyor R-5 Reclaim Tunnel Walls (E q.
