Keenesburg Strip Mine (C-1981-028) MT-07 <br /> <br /> <br />Page 4 <br /> <br />postmining land use of the permit area is also rangeland. The land cannot support a variety of uses <br />under existing technologies and local resources. All attempts at dryland farming on the area have been <br />abandoned. <br /> <br />The premining soil capability class is VIe for irrigated and non-irrigated Valent soils. Osgood soils <br />have capability classes of IVe for irrigated crops and VIe for non-irrigated conditions. <br /> <br />Description of the Operation and Reclamation Plan <br /> <br />Mining activities and ash disposal activities have been terminated at the site. Much of the site <br />reclamation has been performed, and the primary remaining tasks entail the spreading of topsoil <br />(referred to as topsand in CEC’s permit) and seeding. <br /> <br />Topsoil Stripping and Replacement Depths <br />No further stripping of topsoil or topsand is anticipated at the site. Only reclamation activities are <br />anticipated. Replacement depths of topsand are: <br /> <br /> Two feet over overburden spoil cover (on ash disposal areas) <br /> Two feet over roads <br /> Fifteen inches over the long-term spoil area <br /> Six inches over facilities and topsand storage areas. <br /> <br />Revegetation Techniques <br />The approved revegetation plan emphasizes native species planting resulting in a diverse, permanent, <br />effective plant community capable of self-regeneration. The current seed mix is included in Section <br />2.05.4 of the PAP. <br /> <br />Manure or organic mulch is to be spread on the topsand. The approved seed mix will be drill seeded <br />through the organic mulch. Small areas that require reseeding may be broadcast. Two seeding <br />windows exist: <br />1. March 15 to June 1 (spring) and <br />2. September 15 to December 15 (fall). <br /> <br />A stubble mulch (e.g., sorghum) may be applied in the spring or fall prior to seeding of the permanent <br />seed mix. Hay/straw mulch, hydromulch and tackifier, soil amendments, and compost products may <br />also be used. No irrigation is proposed. <br /> <br />The site is currently inspected at least quarterly for pests and diseases. No infestations of pests or <br />noxious weed species have been identified. <br /> <br />Grazing is prohibited during the first two years of vegetation establishment on reclaimed areas. <br />Grazing may be allowed thereafter. Grazing will not be allowed to interfere with vegetation sampling <br />for monitoring or bond release purposes, and eligible areas will not be grazed during the growing <br />season prior to sampling. <br />
