EXHIBIT "D" <br /> Mining Plan <br /> 6.4.4 The Mining Plan for the BIG "G" PIT is as follows (Please also see map): <br /> This will be typical open pit gravel mine located on an upland terrace gravel deposit. An <br /> asphalt hot mix plant and or a concrete batch plant will be set up for projects in the area <br /> from time to time, this use is permitted by the Pueblo County Special Use Permit SUP <br /> Number 2006-008. <br /> (a) This operation of this mine will be carried out in phases. Each phase will <br /> repeat the steps below. <br /> The initial preparation of the surface before extraction of the sand and gravel will <br /> consist of stripping the vegetation and topsoil and placing it in stockpiles for use <br /> later during reclamation. Front-end loaders, scrapers, and Excavators or any <br /> other suitable surface equipment will be used. <br /> Following the stripping of vegetation and topsoil and saving in stockpiles, earthen <br /> berms will be constructed where needed to keep the stormwater from running <br /> into the river drainage this will be part of the stormwater management plan. A <br /> more detailed view of the mining area can be seen on Exhibit "C" the Mining <br /> map. <br /> Extraction of the resource (Pit Run) will be accomplished with front-end loaders, <br /> dozers, scrapers, backhoe excavators, or any surface mining type of equipment <br /> that is economically feasible for this site. <br /> This is an open pit surface mine, and mining and construction equipment <br /> designed for this task will be used for earthmoving and transporting on site. <br /> Mining Excavation will move southeast in the pit Area. The mining will be done <br /> in such a manner as to minimize any high walls and as much as possible the pit <br /> walls will be left at a 3H:1V gradient, or flatter if the terrain permits. <br /> During all phases, Best Management Practices must and will be followed. <br /> (b) All earthmoving will be done with machinery designed for the job, eg. Dozer, <br /> front-end loaders, scrapers, excavators, etc. <br />
