one day off for rest, unforeseen issues, system maintenance, family commitments, etc. This <br />design can be seen in Attachment 2.05.4(2)(e) -1. <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 />organic matter benefits when incorporated during tillage and seedbed preparation prior to <br />seeding of the irrigated pasture seed mixes. <br />Prior to final seedbed preparation, soil conditioning and weed control tillage will be carried out <br />on all retopsoiled areas utilizing techniques such as ripping, chisel plowing and disking. Ripping <br />and chisel plowing will relieve topsoil compaction, aid in controlling weedy species, and will <br />Section 2.05.4(2)(e) Page 3 April 2011 <br />
