EXHIBIT D - Minine Plan <br />(a) Description of the method(s) of mining to be employed in each stage of the operation as <br />related to any surface disturbance on affected lands; <br />]t is estimated that mining operations will be conducted on the site for ten to fifteen years. The <br />current Hazd Rock Redi-Mix operations at the Gray Pit # 1 (M-2003-092) are under a lease <br />agreement until October 10, 2007, with an option to renew for an additional five years. Some <br />concurrent reclamation at the site will be done in the western and central azea of the permit azea as <br />mining is expanded into the additional proposed 5.30 acre extension area. The concurrent <br />reclamation is planned in order to limit the possible increase in the bond amount. Approximately <br />20 acres of the total 23.75 acres will be disturbed and will require grading and seeding. The <br />approximate 3.75 acres that will not require reclamation will be the protected areas around the <br />seeps and some perimeter areas to the north and west beyond the site topsoil stockpile area <br />Access to the site is by an existing farm road from U.S. Hwy 50 at Mile post 101 approximately '/, <br />mile to the south. A commercial access at that point has been installed as per required CDOT <br />specifications and agreements between Hard Rock Redi-Mix and Mc Nick Gray. <br />The permit area currently operating as the Gray Pit # I (#M-2003-092) is a series of small <br />north/south gravel ridges fingering off an east west trending shale ridge {Mancos Shale) <br />sparsely covered by cedar pinion and sagebrush. The gravel/cobble deposits lie above the <br />Mancos Shale/weathered shale in thicknesses from a few to greater than 50 feet. Soil/topsoil <br />occurs intermittently across the site from 0 to 60 inches and there is no distinctive overburden <br />between the soil and the gravel deposit. Slopes are steep to very steep (greater than I S%). <br />Current operations at the site are conducting Facial extraction of the gravel deposits off the <br />slope after reserving existent topsoil in the westside topsoil stockpile area. The remaining site <br />gravel deposits (reserves) are mostly located adjacent to and within the proposed 5.30 acre <br />extension area along and above the current permitted northern boundary of the site. The <br />purpose of this revision is to develop the additional gravel deposit north of the current <br />permitted area. Reclamation at the site will also be enhanced by the proposed expansion <br />area as the east-west ridge can be more effectively contoured and sloped to match the <br />existing topography. Steep reclaimed slopes and remnant highwall segments will be <br />avoided as the ridge can be graded and sloped of both side. In the current active area, there <br />is no overburden or waste rock [o be removed above [he gravel to be mined. There is some <br />overburden 5.30 acre extension area. Overburden is mostly sandy loam topsoil which will be <br />moved and used to slope and cover areas to be reclaimed concurrently as the extension and <br />ridge-top areas are mined The 5.30 additional acres to be added will be marked and staked <br />using steel posts and other delineation as is used for the current permit boundary. <br />The site as mapped and described by [he U.S.D.A. Soil Conservation Service report of June 4, <br />2001, consists of eroded stream terraces with a skeletal overburden of soil. Soils on the site <br />range from 0 to 60 inches and are described as Steep Shallow Clay Loam P,J. Gravel/cobble <br />till deposits underlie the surface soils from a few feet to over 50 feet in thickness along the <br />north/south trending ridges. An advance copy of the current NRCS/USDA soil type and site <br />inspection records for the Gray Pit # 1 are attached In Exhibit I. <br />As is being done for the current permitted activities at the site, mpsoil will be stripped and <br />stockpiled at the W estside topsoil stockpile area for use in subsequent reclamation activities. If <br />topsoil stockpiles are to be left for more than 1 growing season, they will be seeded with the <br />USDA recommended seed mix via broadcast method. <br />Mining will (has commenced is fall of 2002)) commence on [he southwest comer of the property <br />and proceed north then east by removing the gmvet ridges and leaving a gradual slope from north <br />to south with the toe of the slope ending at the existing haul road. Trees and brush will be <br />removed with a dozer and piled at various locations on the site perimeter out of mining and traffic <br />
