s Mr. Don Aldrich • Page -2- 9. Is the road from County Road 18 into the pit a part of the 30 - acres of affected land? It should be part of the permit area if it was constructed as a part of the gravel operation. This is true x whether the road will be revegetated in final reclamation or Left as a road. If the road was pre-existing and is to be left as a road in final reclamation, it need not be included in the permit area. Please clarify this matter. 5. When I inspected the site of this operation, I did not notice any large amount of topsoil stockpiled on the site. I presume that the area X outlined on the map is to be used for this purpose as topooil is brought in during the life of the pit. Please clarify this matter. Exhibit D Mining Plan 1. As topsoil is stockpiled over time, the location of the topsoil should be in an area that is to be as little disturbed by ongoing mining as possible. PSk {Those areas of the stockpile that are to be left for one growing season or ~h''longer should be planted with a perennial grass cover crop for purposes of r'°~~~~ stabilization against wind and water erosion (such as Western wheatgrass ~ ~ Pf,,~ at a broadcast rate of 6.0 IbsJacre). I will discuss the expected amount ° of this stockpiled topsoil under Exhibit E. 2. Although the mining of the 30 acres is probably not to be really formally phased, some distinct areas of the permit area may be mined out and ready to be reclaimed, while other areas of the pit are still being actively worked. These mined out areas should then be reclaimed as soon as possible. Otero County should commit to as much of such concurrent reclamation as possible. X3. Is the existing mined out area of about 3 acres to the west of the permit area to be incorporated into the permit area (now or later). If not, why not? x 4. What equipment (mobile and fixed) is to be used in the mining operation? ~5. What are the planned slopes of the working faces of the pit? 6. Care should be taken not to mine too close to the fence Line (or permit boundaries) since the final slopes are to be 3:1 or Less. Otherwise backfilling of the pit may be necessary to achieve these final slopes. Exhibit E Reclamation Plan 1. My inspection of the site showed a depth of topsoil of about 16". Since the stratum underlying the gravel to be mined is made up of clay materials which are probably relatively unsuitable as rooting material for Liu °~~~~ revegeta tion, a minimum topsoil depth of 8" (or half the original depth) seems reasonable for the site. If the area were totally flat, this would work out to about 32,270 cubic yards. Considering that much of the area will slope at 3:1 or less, a minimum of 40,000 cubic yards of topsoil should be brought in by Otero County in order to reclaim this site.
