RECLAMATION COSTS <br />EXHIBIT L <br />The worst case reclamation scenario will occur when Phase 1 of the expansion area is mined out. <br />At this point in time, most of the Camilletti area will need topsoil and seeding, and the new <br />disturbed area will require backfilling and grading. The reclamation tasks breakdown as follows: <br />1. Remove all facilities and equipment including fuel farm and processing plants. $5,000 <br />2. Backfill expansion area highwall to 3HAV slope. 28,333 CY @ $1.25 /CY = $35,416 <br />3. Topsoil disturbed areas to a depth of 12 inches. 48.0 acres @ 12 inches = 77,440 CY @ <br />$1.25 /CY = $96,800 <br />4. Seed all dryland areas with the approved seed mix. 48.0 acres @ $200 /acre = $9,600 <br />5. Mulch dryland areas, 200 lbs /acre. 48.0 acres @ $400 /acre = $19,200 <br />Worst case reclamation costs for this scenario are shown in Table L -1 below: <br />Hayden Gravel Pit, May 2013 L -1 <br />
