1 i - ~-- Mr. Ed Bischoff Mined Land Reclamation Division July 29, 1980 Page 3 The access/haul road has been included in the technical revision request. The area involved is approximately .5 acres. The .5 acres has been added to the area proposed to be deleted. That acreage is defined as Area 4 on the map and consists of 1.74 acres. The vegetation in the area of the turnaround and borrow areas is typical of that located within the adjacent permit area. The baseline information generated for the permit boundary includes an area some 200' to the east of the proposed disturbance. Elevation, slope and aspect is fairly typical throughout this area. Therefore, there is little or no dif- ference in the vegetation types. For instance, the pinon-juniper and mountain shrub types occur on the lower elevations of the slope fairly uniformly. There is also some Ponderosa Pine interspersed within the two types. This information was previously described in Exhibits C-5 and J of the approved permit. If required by the Division, ditches will be placed in appropriate locations to prevent the contribution of upward flows across the proposed area of disturbance. In addition, small ditches and sediment traps will be utilized to control runoff and sediment yield from the disturbed area. The ditches will be placed downslope. The sediment traps will consist of small depressions bordered by sand- bags on the downstream end. The upstream approach of the sandbags will be lined with polyester film. The downstream end of the sandbags will be rip rapped with small,. non-toxic, non-acid producing rock. The rock will provide for dissipation of any flows generated by runoff. If sediment accumulates it will be removed from the traps as necessary to assure that they function properly.
