<br />The permit area is 47.75 acres in size and will be excavated to provide sand, gravel and borrow <br />material for the azea. The excavation will proceed from north to south in four phases, and be a <br />"dry alluvial" operation. The Plant Site will be located in the northwest corner of the permit area <br />on a 2t acre portion of the 17~ acre Phase 1 mining azea. The other three mining phases will <br />be 10± acres each. <br />There is limited surface material that would qualify as topsoil. When the surface layer has some <br />topsoil material in it, the top l.t.foot this surface material will be snipped from areas proposed <br />for excavation, and stored for later use in later revegetation. For each phase, excavation will <br />proceed from north to south. After snipping and storing 1 ± foot of any usable surface material <br />in each phase area, any unuseable overburden material area will also be stripped and stored for <br />later use in building slopes for revegetation. Both surface material and unusable overburden will <br />be stored along the western portion of each phase area, over areas that have insufficient sand and <br />gravel aggregate material to justify excavation. Surface material, overburden, and sand and gravel <br />aggregate material will be excavated using scrapers, backhoes and other equipment. The excavated <br />material may be loaded directly into trucks, stockpiled, and/or transported to the plant area for <br />processing. All slopes will be left in a reasonably smooth condition, and be a minimum of 2 % and <br />a maximum of 3 horizontal to 1 vertical for final reclamation. <br />Since this is a dry pit operation, there will be no affect or injury to any water rights. Water for <br />washing and dust control will come from the existing Upper Arapahoe well that was permitted for <br />this existing operation (M-83-085), or the operator may also obtain another deep well permit for <br />another well to provide water for these purposes. An Air Emissions Permit for approval of <br />fugitive dust consols, and an NPDES permit for storm water discharge will also be obtained. The <br />haul route for transport of material from the site will utilize the same access that the previous 11+ <br />acre operation utilized under permit M-83-085 utilized - 72nd Avenue to SH79, via an existing <br />private road on other property owned by the applicant to 72°d Avenue. 72°d Avenue is gravel road <br />maintained by Adams County; SH79 is maintained by CDOT and is paved. <br />This will be a 4 phase mining operation of 1 to 2 years/phase, that is expected to last from 5 to <br />10 years total and exsact 1/2+ million cubic yards of material. As mining is being completed in <br />the Phase 1 area, mining will be undertaken in Phase 2. Prior to mining being undertaken in Phase <br />3, reclamation will be completed on 15± acres of Phase 1. Prior to mining being undertaken in <br />Phase 4, reclamation will be completed on 9.5~ acres of Phase 2. As mining is being undertaken <br />in Phase 4, reclamation activities will also be undertaken on 9.5± acres of Phase 3. Finally, after <br />mining is completed in Phase 4, reclamation will be completed on 9.5± acres of Phase 4 and the <br />2± acre Plant Site azea of Phase 1, and revegetation will be repeated on any previously reclaimed <br />areas where revegetation was unsuccessful. Thus, excluding revegetation as needed for areas <br />where the initial revegetation activities are unsuccessful, the maximum disturbed area at any one <br />time will be 30 acres. <br />1 <br />
