D-2 <br /> material(eolian sand),blasting will be unnecessary,and thus is not a component of the mine plan. The <br /> directly excavated material will then be loaded to dedicated off-road, articulated haul trucks that will <br /> initially ramp out of the box cut pit to deliver run-of-mine(ROM)material to the ROM stockpile,to be <br /> situated proximal to the wet plant portion of the processing plant. Once the pit progression has been <br /> established to steady-state conditions, it is anticipated that longer duration central corridor"primary" <br /> haul roads will be utilized to deliver ROM material from outlying mining areas to the plant area. In- <br /> pit haulage will be utilized to access the"primary"haul roads. A representative equipment list and the <br /> proposed mining method and sequence are also further detailed in Attachment D-1. <br /> (c) Atl water diversions and impoundments; <br /> Minimal run-on and/or run-off is anticipated at the location due to the low slope gradients across the <br /> Permit Area and the highly permeable soils(i.e.,eolian sands). In addition,anthropogenic features(the <br /> existing Weld County Road 59 and various service roads) significantly limit or preclude run-on <br /> potential. <br /> As described in Exhibit G:Water Information,regional drainage is generally to the northeast(on the <br /> western portion of the Permit Area),with surface topography gently sloping at a rate of 20 to 30 ft.per <br /> mile. The localized drainage generally trends downward to the north-northeast(toward Ennis Draw) <br /> for those mining areas within Sections 12 and 1,respectively. For those mining areas within Sections <br /> 7 and 6 (the eastern portion of the Permit Area), localized drainage generally trends to the west- <br /> northwest and north-northwest, respectively, again as influenced by the presence of the Ennis Draw <br /> depression. As influenced by a minor ridge locally present along the eastern extent of Sections 7 and <br /> 6,the Section 5 mining area generally drains east-southeasterly. <br /> Notably, the proposed mining area, in its entirety, is comprised of surficial deposits of eolian sands, <br /> thus, there is rapid and high infiltration, with limited runoff potential. In general, CSC has designed <br /> the Keenesburg No. 2 Mine Project to take advantage of these site-specific characteristics; and,due to <br /> the nature of the surrounding area (i.e., the limited area of influence associated with the Permit Area <br /> location),no specific run-on or run-off potential is anticipated. Thus,no specific drainage features are <br /> anticipated. CSC will, however, establish safety berms along pit perimeters; such features will also <br /> serve as "diversion" features to minimize the potential for localized drainage to enter the active pit <br /> areas. With the exception of post-mining(pit)depressions,natural drainage patterns will be generally <br /> restored at time of closure and site reclamation,as further detailed in Exhibit E: Reclamation Plan. <br /> Keenesburg No. 2 Mine_112 Reclamation Operation—November 22,2019 <br />
