• MINING AND RECLAMATION PLAN October, 1979 MT. GUNNISON NO. 1 MINE Revised September 24, 1981 Revised October 7, 1981 east from point B. Refer to attached map. If the topsoil removal area should increase in size the berm would also increase in size to a height not to exceed 9 feet. The ditches will also be extended as needed to minimize the area disturbed. Reclamation is discussed in Section 4.5.7. 3.2 Mine Facilities 3.2.1 Topsoil Handling Prior to construction of the proposed surface facilities at the Mt. Gunnison No. 1 Mine, only those areas to be disturbed during construction will be cleared of vegetation. Topsoil from these areas will be removed with earth moving equipmens and placed in a controlled manner in designated topsoil storage areas. • Prior to the commencement of cut and fill operations, vegetation will be removed with appropriate equipment. Topsoil will be removed and stockpiled for later reclamation use. In areas of high vertical relief, removal of topsoil may not be feasible, but every effort will be made to salvage all topsoil wherever possible. When stockpiled topsoil is not to be replaced on an area immediately, an approved rapid gro.ving vegetative cover or other approved measures will be established to protect *.he stockpile from wind and water erosion. Controlled placement of topsoil in a stockpile will enhance the protection of soil integrity and hydrologic stability. The surface will be cleared of topsoil onl}• as necessary for construction and site cevetopment. As required, topsoil removed will be transported to a designated . i:~_n.11? area iJr later re-::Se In re ~'ege :dtl0n aCtiVlaeS O^-Sae GUring reclamat:on. .qll surface runoff upstream of the topsoil pile will be controlled as part of the surface facilities drainage control.
