RECLAMATION PLAN <br />The selected drill-sites are located on gentle slopes or bench areas to minimize grading <br />requirements. Maximum drill pad dimensions will be 100 x 100 feet; however, Sage Creek will <br />make every effort to minimize the disturbance footprint. In many instances, it is anticipated that <br />the extent of disturbance will be the immediate area around the drill rig and the adjacent mud pits. <br />Construction will be conducted in accordance with Rule 2.02.2(2)(f) and 4.21.4(5) of the <br />Regulations of the Mined Land Reclamation Board for Coal Mining.. Prior to earth-moving or <br />excavations of any type, the A and B horizons will be salvaged and stored in an area that will be <br />undisturbed and not subject to excessive wind or water erosion. At sites that have been <br />previously disturbed by agricultural or mining activities, if there is no distinction between the A <br />and B horizons, the topsoil will be salvaged as a single unit (letter from CDRMS to Mr. Scott <br />Cowman, dated October 6, 2008). The underlying subsoil materials will, if necessary, be <br />salvaged and stored in an area separate from A and B horizon materials. After stripping and <br />stockpiling the topsoil/subsoil materials, minor grading will be completed to establish the drill pad <br />and accommodate the drilling and support equipment. Runoff and sediment contributions from <br />the soil material stockpiles will be controlled through placement of a silt fence or soil berm <br />(approximately one foot in height) downgradient from the stockpile(s). <br />Mud pits will be constructed within the graded pad area. Generally two or three pits are required, <br />with typical pit dimensions of 10 feet x 5 feet and 6 feet deep. The size of the required pits is <br />dependent on the anticipated drilling depths and conditions. Materials excavated from the pits <br />will be stockpiled on the margins of the pad area and used to backfill the pits after the drilling is <br />completed. All drilling fluids will be contained within the mud pits, and all drilling supplies will <br />be contained within the area of the drill pad. Any runoff and associated suspended sediment from <br />the drill pad will be controlled and contained by a perimeter soil berm or silt fence on the <br />downgradient side(s) of the drill pad. <br />Immediately upon cessation of operations, the subsoil will be replaced, with the surface left in a <br />roughened condition. The A and B horizons will then be replaced over the subsoil material in <br />accordance with Rule 4.21.4(5). <br />Proposed Reclamation Methods: The proposed exploration program is designed to minimize <br />new surface disturbance by utilizing existing roads and trails to the extent possible, placing drill <br />pads adjacent to existing roads, utilizing previously disturbed areas for drill pads, and limiting pad <br />size. Surface disturbance, and reclamation requirements and costs calculated by Sage Creek are <br />summarized on Table 1, 2010 Sage Creek Exploration Program Reclamation Cost Estimate. <br />Upon approval of the NOI, Sage Creek will file a corporate surety with the Land Mined <br />Reclamation Board to assure that the reclamation obligations are fulfilled. If CDRMS completes <br />an independent bond calculation estimate as part of the NOI review Sage Creek may choose to <br />file a corporate surety for the least cost estimate. <br />The following sections describe the specific proposed reclamation practices to be used to return <br />areas disturbed by the exploration activities to a stable condition and productive use. <br />2010 RC Admin Permit 5 2124110
