• Exhibit E • <br />feet below the pre-mining contours until the bottom of the valley is reached, where it will <br />average approximately 2 feet below the pre-mining contours. Drainages and slopes <br />will be generally recreated, however, it should be noted that there are little or no <br />developed drainage ways presently existing on the site. Drainage in the widened <br />valley floor will parallel the creek with an outlet channel at the south end of the permit <br />area, as shown in the storm water management plan. <br />RECLAMATION DURING THE FIRST YEARS <br />As soon as possible during mining of Stage 1, including the original 110 permit area, a <br />buffer of grassland will be established along the southeastern corner and southern <br />edge of the permit area to reduce wind erosion and blowing dust. This will also serve <br />as a "test plot" for future reclamation of the entire site, to determine which species will <br />do the best in this particular setting. Assuming that production is at the 60,000 TPY <br />rate, establishment of the first part of this "test plot" will occur in the second or third <br />year of mining activities, when at least'/: acre of the area (B1) is backfilled to final <br />grade. <br />After that, reclamation will generally be done in more compact near-square parcels <br />rather than in strips. In each stage of reclamation, generally the old upland area (bench <br />and slope) will be reclaimed first, then the valley floor (new and old) will be reclaimed. <br />To some degree, the amount of reclamation will be dependent on the amount of <br />material available from fines and stripping of overburden available for backfill. Overall, <br />approximately 360,000 CY of backfill material is needed to achieve the contours as <br />desired, and an estimated 370,000 CY of backfill material is expected to be available. <br />Extra backfill material will be used to establish more gentle transition slopes between <br />the upland and the valley floor where possible. <br />STOCKPILES: <br />Any stockpiles of topsoil and overburden will be seeded with temporary seed mix to <br />stabilize the stockpiles against wind and water erosion. Stockpiles will also be <br />protected as necessary against erosion and traffic. <br />BACKFILLING AND GRADING: <br />Except for the mining of the first area (61), overburden removed during mining will be <br />used to backfill the areas already mined (together with fines from processing). Grading <br />will be done as the backfill reaches final grade. <br />TOPSOIL <br />As discussed in the mining plan, topsoil will be stripped, stored, and placed in a <br />stockpile (separate from overburden) during initial development and throughout the life <br />of the mine. (Refer to Exhibit I for detailed information on topsoil.) <br />VEGETATION <br />Final reclamation will include establishment of aself-sustaining vegetative community <br />of native grasses and forage plants. Reclamation will be deemed to have been <br />accomplished when vegetative cover is capable of regeneration and <br />erosion/sedimentation is equal to or less than that of the original conditions of the site <br />Trans-Colorado Concrete October 99 <br />Application for Permit: Spotted Burro Pit Page 13 <br />
