Overland Conveyor and Railroad Spur The post mining land use of the overland conveyor corridor south of 1 91/0 road was changed to industrial use with approval of TR-57. All disturbance and reclamation in this area was performed upon lands owned/controlled by Union Pacific Railroad. Structures have been removed and regrading and re-vegetation was completed in 2004. The UPRR continues to use portions of the reclaimed areas for their maintenance equipment and for storing of material during times of repair on the rail line. The overland conveyor corridor and railroad spur north of 19/10 road will be converted to industrial use. Haul road no. 3 through this area will be left in place since it lies mostly on railroad property and is used by them for rail maintenance. The rail spur, from immediately north of 19/10 road to the rail loop, and the truck scales will be left in place since they are key features for the industrial use of the area. See Tab 15, page 15-1 for more details on post mining land use. The final contours for the Overland Conveyor and the Railroad spur are shown on Exhibits 7C and 10C. These contours are similar to the. existing contours. Concrete footers and stemwalls remaining after salvage will either be buried with a minimum of 4- feet of cover or hauled to an offsite disposal area. Coal spillage was cleaned-up and hauled to a refuse pile. Light Use Road 5 was eliminated. The berm along the River will remain in place as a permanent structure. The holes remaining at Transfer 2 and 3 were backfilled with adjacent material and the conveyor culvert under the county road near Transfer 3 was partially removed and backfilled. • The area between the conveyor corridor and haul road number 3 was disturbed when the overland conveyor and unit train loadout were being constructed. This area is between the lower segment of Coal Canyon and the rail loop to the north and south respectively. Topsoil was not salvaged from the area. The area is relatively flat and the ground surface blends into adjacent areas. Woody plants (greasewood and rabbitbrush) were either seeded or have invaded the area over the years. The vegetation in this area is judged to be adequate to control erosion based on the fact no erosion has occurred in over 25 years. The majority of this area will be used as a scale/turnaround facility upon approval of land use change. Unit Train Loadout The Unit Train Loadout will be converted to industrial use. The rail loop and a portion of the rail spur will be left in place since it will be the key feature for the industrial use of the area. See Tab 15, page 15-1 for more detailed information on the post mining land use. The final contours for the Unit Train Loadout (UTL) are shown of Exhibit 11 C. Cross sections representing the existing and final grades are shown on Exhibit 59. The final contours were designed to provide a graded smooth site for the industrial use. Grading on this site will primarily involve eliminating the sewage treatment ponds, eliminating the embankment that supported the linear stacker and coal stockpile and backfilling the sediment ponds. A -15 foot high "berm" will be left in place west of the reclaim tunnel to screen some of the structures from I-70.
