For settling /dewatering system for Phase 1 see diagram in Exhibit D - Mining <br />Plan. <br />TOPSOIL HANDLING: Strip to 8" to 24 ". Stockpiles, if created, must be <br />separate from overburden OR placed immediately on land that has been <br />completely backfilled. <br />OVERBURDEN HANDLING: After removal of soil, strip as deep as needed. <br />Either backfill behind mining operations in mined out areas OR use to build <br />sediment basin containment berms. <br />MINING SEQUENCE: Start south of the plant, proceed around south end and <br />then go north to the northwest corner. <br />SEDIMENT BASIN BARRIER BERMS: Location of berms is at operator's <br />discretion. Sediment basin arrangement may not create completely sealed <br />basins. All basins must have at least one side that is hydrologically connected <br />to adjacent unmined land and at least one basin should span the site to allow <br />flow of water from west side to east side of operation. Arrangement shown is <br />suggested only. <br />ANTICIPATED RECLAMATION: Refer to Exhibits E and F for details on <br />reclamation plan. <br />Completely backfilled pit will be reclaimed to riparian (cottonwood) forest, <br />shrublands, and wetlands. Backfilling to 0.5 to 3.0 feet above <br />anticipated water table. Side slopes a maximum grade of 5:1. An outlet <br />will be established into drainage along east side of mined area just <br />north of the junction of the drainage with the river. This will drain excess <br />water from reclaimed land. <br />=,. 11.,;: 11:,;: 11.=. 11.=,: IC=,: If .;,_II:,;',Q:;,:IL;;11.lL; =11'. - ,• u • � :. ra : , : - �� <br />For Phase 1 Affected Land Boundary is samie as permit boundary except for east end of phase. <br />There the Affected Land Boundary follows t:he phase boundary. <br />= M <br />PROPERTY BOUNDARY <br />(Where not congruent with Permit Boundary) <br />PERMIT BOUNDARY <br />MINING LIMIT <br />JAN 312607 <br />PRE- MINING TOPOGRAPHY' Division ofReclamattcn, <br />Mining and Safety <br />TREE LINES (PREMINING) <br />THIS MAP REPLACES <br />PREVIOUS EXHIBIT C -4 <br />Permit# Confidential? ,)o <br />Class ° ar t i n _'type Sea A M:_-93 <br />MV #= inspection Date <br />Doc Date (if no date stamp) a u <br />n _ A A -O• .. 1 r>o�,at AA ih i>7A T_Ild�l:J[M' <br />voo i�a,uc {l5 <br />From D S /Other r ntf 11Cnfc I t? <br />Re Other <br />Rec tents KtIL <br />Revised: 01/07 <br />Amendment 3 <br />Revised:Otil04 <br />Amendment 2 <br />Revised: 09/02 <br />add Aquila power line, <br />scale: 1" = 300' <br />contour interval = 2' <br />Continental Materials (M- 1986 -015) <br />East Pit - Transit Mix of Pueblo <br />Exhibit C- 4A - PHASE 1 DETAIL <br />MINING PLAN <br />C4A - amend 3 Phase 1 Detail Map.dwg <br />
