3.3 BACKFILLING AND GRADING <br />3.3.1 Backfilling and Grading -Lower Road <br />The portion of the access road on the Munger Canyon Valley floor was in place <br />prior to mining. The road was only widened and graveled for mine use. The plans <br />approved for the expanded mining activities included realignment, widening, installation <br />of a parallel conveyor, and paving the road surface with asphalt. In reclamation the <br />paving would have been removed, and the road reduced to ten feet wide providing <br />continued access to the east for local ranchers. Since the expansion was not done, <br />these modifications were not completed. No areas of the lower road are steep enough <br />to present slope stability problems. <br />Currently, the edges of the road are revegetated and the road bed is in excellent <br />shape. Reclamation of the lower road is shown on Figure 2.2-7C. The Operator will <br />comply with the BLM Area Managers letter of December 3,1996 regarding reclamation <br />of the lower portion of the road ,See Appendix L in Volume III. Specific procedures to <br />comply with the BLM concerns are: <br />X The road profile will be left in place. <br />X Both sides of the road will be revegetated leaving an eight foot wide <br />running surface in the center of the road profile. The sides of the road will <br />be chisel plowed and disk harrowed to a depth of six inches to create a <br />seed bed. The sides of the road will then be broadcast seeded with the <br />Big Sagebrush Shrubland seed mixture shown in Table 3.4-1. (Although <br />the sides of the road will be revegetated, this area is not shown on Figure <br />2.2-7C since strips along the road are so thin.) <br />X Culverts will be removed and low water crossings (fords) shall be cut to <br />the bottom of the streambed. No fill material will be placed into the <br />drainage. Excess cut material remaining from the ramp construction will <br />be used to backfill the mine site and will not be left in place at the fords. <br />The edges of the ramps to the fords will be revegetated. <br />TR-22 3-6 05/07 <br />
