This stockpile stores soil, <br />subsoil, and backfill material (excavated material other than sand and gravel). <br />Approximately 580 feet of the south stockpile/berm will be used in 2011 to backfill and <br />create the final shoreline of the current pond, to open the first strip of the South Field to <br />be mined. Soil from under the berm will be used for that purpose or to extend the west <br />berm/stockpile (along the highway) to the south. Soil stripped from the rest of the <br />South Field will be used to construct extensions of the east and west berms. The <br />existing gap on the east will remain. <br />Because of the relocated south berm (the new south shore of the current pond) and the <br />wooded area to the south of the new permit boundary blocks views and shelters <br />operations, a berm of stockpiled materials (soil and backfill) will probably not be <br />constructed at the south end of the new permit area, although a small one may be <br />constructed. If one is, at least one gap will be included in it, near the southeast corner. <br />Otherwise, refer to stockpile information in the original Exhibit D. <br />SURFACE WATER MANAGEMENT: <br />There is no change to surface water management as included in the original Exhibit D. <br />This exhibit and other exhibits and drawings continue to serve as the storm water <br />management plan for the site, with the sole discharge outfall being the controlled outfall <br />at the extreme south point of the permit area, into the Dolores River. <br />ASSUMPTIONS USED IN MINING PLAN: <br />No changes from original Exhibit D. <br />MINING OF SOUTH FIELD (NEWLY-PERMITTED AREA): <br />riUUic v-L+ JVULii VClu <br />and maintain <br />cut for safety. <br />SHA - Safety <br />?1Ae <br />?/ Berm 3' high <br />Use materlal <br />from berm <br />to backfill <br />shore of pond <br />Ground Level <br />To access the South Field past the current pond, a bench will be cut in the south <br />portion of the west stockpile/berm, as shown in the figure above. Pit run material will be <br />used to surface this road, and reclaimed once mining of the South Field is done. <br />Mining will be done in six annual strips 75 feet wide and approximately 540 feet long, <br />moving south from the south shore of the current pond. This will be excavated as a <br />single cut, to the sandstone bedrock, creating a new pond. <br />Stone Sand & Gravel, LLC 15 MAR 2011 <br />Application for Amendment to Permit M-2001-001: Line Camp Pit SSG-LCP-D1-001
