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 Millcvetch <br />A discussion of the planned introduced species in included in Section 2.05.4, Reclamation Plan <br />4.15.3 SEEDING AND PLANTING <br />Seeding and planting of disturbed areas will occur during the first favorable planting period following completion of topsoil <br />replacement. Permanent seeding will typically occur in the fall. <br />4.15.4 MULCHING AND OTHER SOII. STABII.IZING PRACTICES <br />EC 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 designed <br />post-mining topographic configuration. In areas where the post-mining configuration results in long uninterrupted <br />slopes, EC plans to utilize small-scale terrace features and contour ditches to limit sheet flow and minimize erosion. <br />Topsoil material will be replaced along the contour wherever possible and will be left in a roughened condition to <br />minimize runoff and erosion until a permanent vegetative cover can be established. <br />4.15.5 GRAZING <br />In areas where the affected land will be returned to apost-mining land use of pastureland (hayland) or rangeland/wildlife, <br />grazing areas and numbers of animals to be grazed will be determined at the time the land is ready for grazing. Grazing <br />utilization will be controlled by a management plan developed in cooperation with the surface landowner and the <br />CDMG. EC will utilize the grazing management plan to ensure that grazing activities do not preclude or interfere with <br />post- mining vegetation sampling and evaluation of the success of vegetative reestablishment. <br />4.15.6 FIELD TRIALS <br />EC does not plan to conduct any field trials in conjunction with the planned operation. <br />4.15.7 DETERMINING REVEGETATION SUCCESS: GENERAL REQUIREMENTS AND STANDARDS <br />In determining revegetation success, the EC operation is divided into two (2) distinct components: 1) those areas <br />disturbed prior to May 3, 1978, and 2) those areas disturbed after May 3, 1978. Some areas were disturbed prior to May <br />3, 1978 and re-disturbed after May 3, 1978. EC has developed a Reclamation Plan Map (Map 29) which graphically <br />shows [he areas disturbed and dates of disturbance. In addition, EC had developed a Vegetation Map (Map 20) which <br />shows the various locations of reference areas to which revegetation success will be judged. <br />4.15.8 REVEGETATION SUCCESS CRTTERIA <br />EC will comply with all standards as set forth in 4.15.7 and 4.15.8. Since many areas affected by the mining operations <br />were disturbed prior to May 3, 1978, and some areas were re-disturbed after May 3, 1978, the CDMG is referred <br />to Section 2.05.4, Reclamation Plan, for revegetation success details. <br />Permit Revision 04-34 4.01-10 Revised 7/2/04 <br />
