11 X. Topsoil - Rules 2.04.9, 2.05.3(5), 2.05.4(2)(d) and 4.06 Baseline soils information and the topsoil removal and redistribution plans in Volume I, pages 3-109 to 3-1Z3 and 4-65 to 4-68 and Volume II, Appendix 3.5-1 were reviewed for compliance with the regulations. Five soil types occur within the proposed permit area: the Heldt Silty clay; Nihil Stony loam; Ascalon loam; Ustic Torriorthents-Rock Outcrop Complex; and Irock Stony loam. The table below shows how much topsoil is to be salvaged from each soil type. Soil Type Average Salvage Depth Heldt Silty clay 60 inches Nihil Stony loam 12 inches Ascalon loam 60 inches Ustic Torriorthents-Rock Outcrop 0 inches Irock Stony loam 0 inches No soil will be salvaged from the Ustic Torriorthents-Rock Outcrop because these soils occupy steep slopes and are too rocky to be used as a source of topsoil. No soil will be salvaged from the Irock Stony loam because this soil is too rocky to be used as a source of topsoil. Sufficient topsoil is available from the Heldt, Nihil and Ascalon soils for reclamation and of better quality than the Irock and Ustic Torriorthents. Therefore, the requirement of Rule 4.06.2(4) is met. Textures of these soils range from loam to silty c]ay. All the soils have a low electrical conductivity (EC) and sodium absorption ration (SAR). Most of the surface and subsurface soil horizons rate fair to good as a source of topsoil material. Topsoil will be salvaged from all areas proposed to be disturbed and placed in topsoil stockpiles. The location of topsoil stockpiles for the coal refuse impoundment are shown on map 3.5-1. The applicant did not indicate where topsoil from the surface facilities area will be stockpiled due to potential requirements for visual barriers by Garfield County. Therefore, the following stipulation is necessary: Stipulation No. 7 THE PERMITTEE MUST SUBMIT A PLAN TO THE DIVISION SHOWING WHERE ALL TOPSOIL SALVAGED FROM THE FACILITIES AREA WILL 8F STOCKPILED. THE PERMITTEE MUST OBTAIN DIVISION APPROVAL OF THIS PLANE PRIOR TO ANY DISTURBANCE. The soils resource information shows that the applicant has insufficient topsoil at the coal refuse impoundment area to meet the requirement of Rule 4.10.4 for replacing four feet of cover over the coal refuse. The applicant proposes to strip additional material as non-toxic, non-combustible cover following topsoil removal. The topsoil will be stored in two stockpiles and the overburden will be in one stockpile, all above the coal refuse impoundment. Several deficiencies still remain in the topsoil salvage plan at the coal refuse impoundment which must be resolved before the Division can approve this portion of the proposed operation.
