EXHIBIT E—Reclamation Plan (Rule 6.4.5) <br /> • 8. Phase 2 Area— What is the estimated volume of topsoil needed to reclaim the <br /> slopes around the pond and what depth will topsoil be placed? <br /> ➢ Response: <br /> ✓ To the best of our knowledge topsoil has been placed on all of the Phase 2 <br /> area at-an average depth of 6 inches. The topsoil in place will remain in place <br /> and simply regraded and reseeded to the approved seed mix. <br /> • 9. Phase 2 Area—Please clearly show on a map the areas that require grading and <br /> topsoil placement? <br /> ➢ Response: <br /> ✓ Please see the revised Reclamation Plan Map F-1 <br /> • 10. Phase 2 Area— Where is the proposed source of topsoil and what methods will <br /> used to transport the topsoil. <br /> ➢ Response: <br /> ✓ Topsoil: As stated above, we have already applied the required topsoil to <br /> Phase Two. The area needs some minor grading, seedbed preparation and <br /> seeding. <br /> ✓ In addition, we may need to apply soil amendments based on the site specific <br /> soil test already provided to the DRMS. <br /> ✓ The total area in Phase 2 which received replaced topsoil is approximately <br /> 19.0 acres. <br /> • 11. Phase 2 Area -Does the operator anticipate that topsoil stockpiles located in the <br /> Phase 2 Area will be used for reclamation in other phases?If so,please describe <br /> how these areas will be reclaimed. <br /> ➢ Response: <br /> ✓ We have identified six topsoil piles on-site. The estimated cubic yards in <br /> each topsoil stockpile are as follows: <br /> ❖ Phase 2, north of the reservoir, equals an estimated 51,000 cyds. <br /> ❖ The pile north of the Phase 2 reservoir and just west of Phase 1, equals <br /> approximately 3,348 cyds. <br /> ✓ Topsoil Removal Reclamation: <br /> ❖ Each Phase which has backfill material removed will involve first <br /> stripping and stockpiling or direct haul of the topsoil to the area needing <br /> topsoil replacement <br /> ❖ Once available overburden has been removed, the area will have the <br /> topsoil replaced, the seedbed will be prepared by disking and harrowing, <br /> as needed. <br /> 13 <br />
