The Umbarg 2 and 3 samples showed aluminum concentrations (4.9 -5.6 <br />ppm) at or slightly above the Munshower suspect levels. As with iron, no <br />metal symptoms were apparent in the vegetation. <br />The Lazear samples contained 44 -45 percent clay in their textural <br />analysis. This percentage exceeds the suspect level for Montana and is <br />borderline suspect for New Mexico (the only other state to specify a <br />numerical suspect level for clay). For this reason, and the variability of <br />depth and likelihood of encountering undesirable rock fragments, the <br />applicant proposes to exclude the Lazear soils from salvage for <br />reclamation. <br />Based on the results of soil sampling and field identification and <br />mapping, the Umbarg soils appear suitable for use in reclamation. If <br />disturbed, the Sanchez series soils can provide limited amounts of <br />suitable soil for reclamation. Lazear series soils, given their <br />concentration of clay and relative shallow and stony nature are not <br />particularly suited for reclamation. The depth and extent of the Umbarg <br />soils within the area for surface disturbance, make salvage of these soils <br />in sufficient amounts for reclamation preferable. <br />TR -22 Drill Site Locations <br />Technical Revision TR -22 to this permit document consists of drilling <br />exploration core drill holes on State of Colorado Lease CO -3388. This <br />exploration drilling program involves completion of up to 9 boreholes, all <br />within the C- 1981 -035 permit area. The boreholes further define coal <br />reserves for future mine planning. All of the proposed boreholes will be <br />drilled utilizing already disturbed portions of the access roads. <br />SWCA Environmental Consultants of Durango, Colorado performed a <br />natural resource survey of the proposed drill sites and issued a report <br />dated April 11, 2014 (see Appendix 8(5). <br />GCC Energy, LLC King II Mine <br />Section 2.04.9 <br />Page 3 May 7, 2014 <br />7k22 <br />O- ?'
