' Exhibit D - Mining Plan <br />' The area to be mined is approximately two miles south of Bayfield and <br />lies on the alluvial plains above the Los Pinos River at an elevation of <br />approximately 6,750 feet. The site to be affected is an gravel of pit <br />' that has been mined intermittently since about the 1440's. Historically, <br />the site was mined relatively shallow, averaging about five to seven feet <br />' in depth, and encountered groundwater. The operation will thus form a lake <br />over much of the affected area for final reclamation. Exhibit G provides <br />' some additional discussion regarding the hydrology of the site. <br /> The area will be mined in basically just two phases as illustrated on <br /> the Exhibit C map. The anticip ated direction of mining and location of <br /> stockpiles is also portrayed on this map. Phase 1 will work primarily in <br /> the existing pit deepening the pit to an average of about 12 ± feet from its <br />' <br /> present average of about seven feet deep. In add ition, the work in Phase <br />' one will expand the pit in a westerly direction another 50-75 feet beyond <br />its present size. The remainder of Phase 1 is planned to remain <br />undisturbed. <br />Phase 2 will expand the pit in an easterly direction to the limits of <br />' the permit area, at approximately the same depths to be achieved in the <br />' Phase 1 portion of the operation. Product stockpiles, processing and <br />topsoil stockpiling will probably occur on the Phase 2 area during mining <br />' of Phase 1. Refer to the Exhibit C map illustrating the anticipated <br />location of various mining-related features. It is planned that most of <br />the mining in the existing pit will occur primarily during the months of <br />' February, March, April and May when the water table is at its lowest point, <br />and that the pit will be wet mined using a frontend loader and dozer.
