Rangeland/Wildlife, Cropland, and Pastureland (Hayland). <br />Only the rangeland wildlife seed mixture will contain introduced species. These species include: <br />• Pubescent Wheatgrass <br />• Hard Fescue <br />• Birdsfoot Trefoil <br />• Cicer Milkvetch <br />A discussion of the planned introduced species in included in Section 2.05.4, Reclamation Plan. <br />Seeding and planting of disturbed aeeas will occur during the first favorable planting period following completion of <br />topsoil replacement. Permanent seeding will typically occur in the fall. <br />4.15.4 MIJI,CHING AND OTHER SOIL STABILIZING PRACTICES <br />CEC plans to utilize specific mechanical soil stabilization practices during regrading, topsoil placement, and seedbed <br />preparation activities. Backfilled areas will be regraded to the most moderate slope practical consistent with the <br />designed post-mining topographic configuration. In areas where the post-mining configuration results in long <br />uninterrupted slopes, CEC plans to utilize small-scale terrace features and contour ditches to limit sheet flow and <br />minimize erosion. Topsoil material will be replaced along the contour wherever possible and will be left in a <br />roughened condition to minimize runoff and erosion until a permanent vegetative cover can be established. <br />r ~ <br />L_J <br />In areas where the affected land will be returned to apost-mining land use of pastureland (hayland) or <br />rangeland/wildlife, grazing aeeas and numbers of animals to be grazed will be determined at the time the land is ready <br />for grazing. Grazing utilization will be controlled by a management plan developed in cooperation with the surface <br />landowner and the Division. CEC will utilize the grazing management plan to ensure that grazing activities do not <br />preclude or interfere with post- mining vegetation sampling and evaluation of the success of vegetative <br />reestablishment. <br />CEC does not plan to conduct any field trials in conjunction with the planned operation. <br />4 15 7 DE RMINRJ RE G TATION CCESS• ENE i, REQUIREMENTS AND STANDARDS <br />In determining revegetation success, the CEC operation is divided into two (2) distinct components: I) those areas <br />disturbed prior to May 3, 1978, and 2) those areas disturbed after May 3, 1978. Some areas were disturbed prior to <br />May 3, 1978 and re-disturbed after May 3, 1978. CEC has developed a Reclamation Plan Map (Map 29) which <br />graphically shows the areas disturbed and dates of disturbance. In addition, CEC had developed a Vegetation Map <br />(Map 20) which shows the various locations of reference areas to which revegetation success will be judged. <br />CEC will comply with all standards as set forth in 4.15.7 and 4.15.8. Since many areas affected by the mining <br />operations were disturbed prior to May 3, 1978, and some areas were re-disturbed after May 3, 1978, the Division is <br />referred to Section 2.05.4, Reclamation Plan, for revegetation success details. <br />Permit Renewal No. 3 4.01-10 7/15/98 <br />
