6.4.4 Exhibit D <br /> Mining Plan <br /> The McClave Ranch Pit will be a regular 112 Operation in Bent County. Access to the <br /> site will be from Bent County Road 11 at the northwest corner of the site. <br /> The site consists of Cascajo very gravelly sandy loam, Kimera loam, and Olney sandy <br /> loam. It is anticipated that shale will be found immediately beneath the material to be mined. <br /> The target gravel source is located beneath limited topsoil of 0-6 inches and overburden of an <br /> additional 1-3 feet. Aggregate material is anticipated to be an additional 10 feet in depth. <br /> Topsoil and overburden will be saved for reclamation of the mine site. The primary <br /> commodities of this site are landscape aggregate,gravel and road base. Incidental materials <br /> not used for construction material will be used to reconstruct the pit floor and lessen the pit <br /> slopes. <br /> The life of the proposed operation is difficult to quantify due to the changing economic <br /> conditions in the construction industry and aggregate quality. Extraction will be limited to <br /> 70,000 tons per year. At this rate,the life of the mine would be approximately 10-15 years <br /> depending on local economic conditions. <br /> Mining will proceed to the south of the entrance and then proceed east. Extracted <br /> material will be moved to the processing area that is anticipated to be in the west central <br /> portion of the pit. Earthmoving will be accomplished using front end loaders. Aggregate will be <br /> processed and sized using a crusher and screens. All equipment will be portable. The highwall <br /> will be no greater than 200' in length and less than 10' in height. Mining will occur in 20-acre <br /> phases. Reclamation will occur concurrently to mining and as one 20-acre phase is completed, <br /> a second phase will open. <br /> All plant growth material and topsoil will be salvaged and stockpiled for reclamation <br /> use. These stockpiles will be located at the perimeter of the site and posted as reclamation <br /> topsoil. Waste rock and overburden will be stockpiled and used to rebuild the pit floor and <br /> slopes during reclamation. Established stockpiles will be stored onsite and seeded with the <br /> approved seed mix to reduce the chance of erosion. These stockpiles will be located separate <br /> from the landscape aggregate and gravel stockpiles. <br /> Overburden perimeter stormwater berms will be constructed as excavation and <br /> reclamation progresses. These berms will serve to control erosion and keep sedimentation <br /> from reaching any drainage. Water for dust suppression will be obtained from the nearby <br /> Verhoeff Well and hauled onsite. <br /> There will be no storage of fuel or lubricants onsite. Fuel will be hauled onsite as <br /> needed by vendor trucks. <br /> Page 5 of 16 <br />
