Westside Gravel <br />Division Of Minerals & Geology <br />Construction Material 112 Permit Application <br />EXHIBIT D <br />Mining Plnn <br />Westside Gravel proposes the mining of sand and gravel in a phased operotion. In <br />each phase between ten and fifteen acres will be disturbed at arty given time. <br />Please refer to the necompnrrying pre mining plan map (Exhibit C) for layout <br />information. Phase I will be our initial set-up point. In accordance with nn <br />agreement with Ln Plata County Road ~ Bridge Department, Westside gravel will <br />mine and place pit run material on the county rood accessing the property. <br />Material from phase 1 will be mined and hauled io cori~ply wish this a;~r~een~~er~t. <br />This will create a "bench" approximately 12' below naturktl ground. This bench urea <br />will be the location of the initial crusher set up. The remainder of this phase will <br />be crushed and stockpiled on this bench. P•ll minirw will be clone with dcjiers and <br />loaders and/or hoes. No explosives will be used on this site. linuling will be by <br />trucks. <br />Mining in all phases on the carryon rim will be from 12 to 50 feel deep. All siope< <br />will be left with slopos for flatter than 3:1 where passible. Mining from the canyon <br />face will be completed with the final configur*ntion leaving 3:1 or flutter slopes <br />from the canyon floor to the rim above. Reclamation will follow behind the raining <br />operation as closely as is practical. <br />During the first year of operation it is estia-mted that approxirr~iely 6(KP tuns of <br />material will he processed and transported per day. It is anticipated that each <br />phase identified on the pre mining map will take from three to five years to <br />complete. <br />Initial observations ir;dicate a minimal nrnount of overburden, most areas having <br />less than 10" of overburden/topsoil. Overburden/topsoil will be stripped and <br />stockpiled during the mining operation for each of the phases. the overburden wilt <br />be replaced after mining opernPions as shown in the reclamation plan and map. <br />Sand and gravel will be mined and pror-~sced for use- as r•ond base, concre_te_ <br />aggregates, and/or hot asphalt aggregates. Reject material from the crusher <br />operation will be stockpiled and used to flatted slopes during reclamation. <br />
