within the permit area. These species include Colorado Butterfly Plant, Ute Ladies' Tresses <br /> Orchid, and Western Prairie Fringed Orchid. <br /> Wildlife is limited to small rodents,primarily field mice, and birds, including an owl that is often <br /> seen at Sediment Pond 2. Deer and pronghorn are rare, as are most higher order vertebrates,but <br /> pronghorn and coyotes have been seen at the site. There are no known threatened or endangered <br /> animal species, nor habitats for these species, in the area. The IPaC program states that there are <br /> no critical habitats within the permit area. <br /> The premining land use classification of the area was rangeland, as shown on the general soil <br /> map of Weld County (from the Soil Conservation Service and included in the PAP on page 37). <br /> The current postmining land use of the permit area is also rangeland. The land cannot support a <br /> variety of uses under existing technologies and local resources. All attempts at dryland farming <br /> on the area have been abandoned. If approved, this permit revision would alter the postmining <br /> land use for the site to include the option of industrial/commercial. <br /> The premining soil capability class is VIe for irrigated and non-irrigated Valent soils. Osgood <br /> soils have capability classes of IVe for irrigated crops and VIe for non-irrigated conditions. <br /> Description of the Operation and Reclamation Plans <br /> Mining activities and ash disposal activities have been terminated at the site. Most of the site <br /> reclamation has been performed, including the spreading of topsoil (referred to as topsand in <br /> CEC's permit) and seeding. <br /> Topsoil Stripping and Replacement Depths <br /> No further stripping of topsoil or topsand is anticipated at the site. Only reclamation activities <br /> are anticipated. Replacement depths of topsand are: <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 /> Revegetation Techniques <br /> The approved revegetation plan emphasizes native species planting resulting in a diverse, <br /> permanent, effective plant community capable of self-regeneration. The current seed mix is <br /> included in Section 2.05.4 of the PAP. <br /> Manure or organic mulch was spread on the topsand. The approved seed mix was drill seeded <br /> through the organic mulch. Small areas that require reseeding may be broadcast. Two seeding <br /> windows have been used at the site: <br /> 1. March 15 to June I (spring) <br /> 2. September 15 to December 15 (autumn). <br /> Keenesburg Strip Mine Page 4 <br /> October 2024 Findings for PR-03 <br />
