-24- <br />uptake by plants. To mitigate this problem, CCMC originally proposed <br />selective overburden handling procedure. Low SIUt overburden was to be <br />stockpiled then spread over the regraded spoil. Topsoil would then be <br />spread over the low SAR overburden. The resultant depth of cover over <br />the unsuitable overburden would be at least four feet. <br />While isolation of the unsuitable overburden from the rooting zone was <br />advisable, data provided by the applicant and visual site inspection of <br />soil materials along gully walls by Division staff indicated that more <br />soil material was available for reclamation than was implied in the <br />application. Therefore, the Division requested that CCMC re sample the <br />soils to determine if suitable soil material existed which could be used <br />in place of selected low SfU2 overburden. <br />CCMC subsequently re sampled all the soil types within the area to be <br />disturbed by mining operations. The depths of suitable soil material was <br />found to exceed five feet on all the soil types except the <br />Louviers-Travessilla. The Louviers-Travessilla soil type is generally <br />associated with the pinyon-juniper vegetation type, and is shallow, <br />rocky, and discontinuous. <br />Due to relatively thin N horizons, the applicant proposes to remove the A <br />and B horizons together where they both exist. These horizons will be <br />handled as topsoil. The C horizon material will be removed separately <br />and handled as subsoil. <br />The total thickness of soil removed will average four feet in the mining <br />area and two feet in the facilities areas. <br />Duriny the initial phases of mining, the soil material will be stored in <br />stockpiles. These stockpiles will be in suitable locations. Beginning <br />in the third quarter soil will be immediately replaced on regraded spoils <br />whenever possible. Replacement depths will average 33 inches of subsoil <br />and 15 inches of topsoil. <br />N11 available information indicates that soils should not be a limiting <br />factor in reclamation. <br />The proposed operation is in compliance with the requirements of this <br />section. <br />XII. Vegetation - Rules 2.04.10,L.U5.4(2)(e) and 4.15 <br />The Division has reviewed the applicant's permit application for <br />compliance with these sections. Information on baseline vegetation can <br />be found in Section 2.04.10 (pages 2.04-63 through 2.04-72) and exhibit <br />19 of the application. Information on the revegetation plan can be found <br />in Section 2.05.4 (pages 2.05.73 through 2.05-52). Revegetation <br />performance standard information can be found in Section 4.15 (page <br />4.15-1 through 4.15-4). <br />
