tillage operations may be required to get adequate control. Harrowing and cultipacking prior to <br /> seeding will be conducted as needed in order to provide the smooth, firm seedbed required. In <br /> any areas that may be poorly drained, tillage will be timed in order to reduce bogging, excessive <br /> compaction and excessive cloddiness caused by tillage when soils are wet. The best period for <br /> tillage in these areas may be in the early spring prior to the irrigation season (prior to mid-April). <br /> Section 2.05.4(2)(d), Topsoil (Redistribution), contains additional information on subsoil and <br /> topsoil conditioning. <br /> Irrigation Designs <br /> Areas reclaimed as Irrigated Pasture or Intensively Managed Irrigated Pasture will be irrigated <br /> using either center pivot or sideroll irrigation. Map 2.05.5-1 shows all areas which will be <br /> reclaimed as Irrigated Pasture or Intensively Managed Irrigated Pasture on the Garvey property. <br /> The designs for all irrigation systems are shown in Appendix 2.05.4(2)(e)-1 for the Irrigated <br /> Pasture and Intensively Managed Irrigated Pasture areas. Map 2.05.4(2)(e)-1 shows the design <br /> and layout of the irrigation systems. The extent of irrigation on the Garvey property will be <br /> based on the amount of shares that are available to them from the CCC Ditch for this area. <br /> Revegetation Methods <br /> As discussed in the narrative relating to the proposed postmining land uses found in Section <br /> 2.05.5, the majority of the mining disturbance areas will be reclaimed to a postmining land use <br /> which is similar to, or improved relative to the premining conditions. As described in the <br /> discussion on Topsoil Redistribution found in Section 2 2.05.4(2)(d), topsoil replacement <br /> operations may be carried out during most of the year, the exception being those periods when <br /> wet conditions would preclude handling of the topsoil materials due to potential soil compaction <br /> problems. Prior to replacement of topsoil, the graded spoil will be ripped to reduce compaction. <br /> Detailed topsoil handling and replacement plans are provided in Section 2.05.4(2)(d), Topsoil <br /> Redistribution. In areas where irrigation is proposed, such as on the Intensively Managed <br /> Irrigated Pasture and Irrigated Pasture areas, or on other locations where irrigation water might <br /> be available to promote initial stand establishment, seeding may be carried out as late as July 15. <br /> This will allow for a 75-90 day growing season, enough time to establish an adequate stand <br /> capable of over-wintering. Fall dormant seedings may be made into annual grain stubble if the <br /> potential for competition from established weedy species is not great. For situations where <br /> temporary stabilization is required outside of the normal seeding periods, and the stabilization <br /> period is less than one year an annual grain cover crop of barley, winter wheat or sorghum or <br /> Sudangrass will be used, Seed Mix #2. At times, the size or shape of the retopsoiled areas and <br /> shape of the reclaimed area in relation to a management unit may be insufficient to warrant <br /> establishment of the perennial irrigated pasture species initially. When this occurs, and the <br /> period before establishment of permanent irrigated pasture will extend beyond a year, Seed Mix <br /> #3 - Temporary Reclamation will be used. This mix will provide interim stabilization as well as <br /> Section 2.05.4(2)(e) Page 2 April 2016 (PR-01) <br />
