( ~ ~ <br />,~ <br />EXHIBIT C - MINING PLAN <br />Z. THE PURPOSE OF THIS PERMIT APPLICATION IS TO HAVE <br />AVAILABLE TO THE APPLICANTS A DEPENDABLE SUPPLY OF SAND AND <br />GRAVEL FOR VARIOUS CONSTRUCTION PURPOSES IN THE PROXIMITY OF <br />CRAIG, COLORADO. THIS IS IMPORTANT FOR THE APPLICANTS IN ORDER <br />TO BID COMPETITIVELY ON THE AREA CONSTRUCTION JOBS. <br />T. THE PIT WILL BE WORKED INTERMITTENTLY. IT ]S THE <br />APPLICANTS BEST GUESS THAT WORK WILL BEGIN $EPTEMBER 15, <br />1990 AND END $EPTEMBER 15, Z~~~. <br />3. THE AFFECTED AREA IS IN AN EXISTING WHEAT FIELD. THE <br />APPLICANTS PLAN TO REMOVE APPROXIMATELY )2 INCHES OF TOPSOIL <br />FROM THE SURFACE INTENDED FOR DISTURBANCE AND STORE THIS <br />MATERIAL IN THE DESIGNATED AREA SHOWN ON EXHIBIT E-1. A SIGN <br />WILL BE POSTED STATING THAT THE MATERIAL IS FOR RECLAMATION <br />ONLY. WHEN IT IS PRACTICAL FOR THE ~PERATDRS TO GRADE AND <br />REAPPLY THE TOPSOIL IMMEDIATELY AFTER MINING THEY PLAN TO <br />DO S0. HOWEVER, WITH THE NATURE AND NEED FOR SAND AND <br />GRAVEL, THERE WILL BE EXTENDED PERIODS OF TIME THAT THE <br />EXCAVATIONS WILL HAVE TO REMAIN OPEN. IN THESE INSTANCES, <br />THE TOPSOIL WILL BE STORED IN THE DESIGNATED AREA AND THE <br />OPERATORS WILL STABILIZE THE SOILS STOCKPILES BY SEEDING <br />THEM TO PERENNIAL NATIVE WESTERN WHEAT GRASS BROADCAST AT <br />THE RATE OF ~.5 POUNDS OF PURE LIVE SEED PER j~0~ S0. FT. OF <br />AREA. THE SITES DESIGNATED FOR STOCKPILE STORAGE ARE OUT OF <br />THE WAY OF MINE TRAFFIC, STREAM CHANNELS AND DRAINAGEWAYS. <br />4. THE PRIMARY PRODUCT WILL BE SAND AND GRAVEL. THESE <br />MATERIALS ARE OVERLAIN BY A SANDY CLAY MATERIAL THAT W]LL <br />RUN BETWEEN ~ AND 6 FEET IN DEPTH. MOST OF THIS SANDY CLAY <br />WILL BE USED IN THE ROADBASE PRODUCT. THE EXCESS OVERBURDENr <br />IF ANY, WILL BE RETURNED TO THE MINED-OUT PORTIONS OF THE PIT <br />AS THE MINING PROGRESSES. <br />5. THE SAND AND GRAVEL DEPOSIT IS LENTICULAR AND VARIES <br />FROM 3 FEET IN THICKNESS TO J,5 FEET. THE AVERAGE COMBINED <br />THICKNESS OF THE CLAY AND GRAVEL ]S ESTIMATED TO BE )5 FEET. <br />6. THE MAJOR COMPONENTS OF THE MINE ARE THE PIT AREA AND <br />THE TOPSOIL STORAGE AREA. THE DESIGNATED TOPSOIL STOCKPILE <br />AREA MOST LIKELY WILL NOT BE MINED DUE TO THE THICKNESS OF <br />THE OVERBURDEN. <br />~. THE SIGNIFICANT DISTURBANCES WILL BE THE PIT AREA AND <br />THE TOPSOIL STORAGE AREA, WHICH, WHEN COIf~BINED WILL NOT <br />EXCEED 9.32 ACRES. ~$EE EXHIBIT E AND E-1) <br />
