~~ <br />CIVIL RESAURCES,LLC <br />topsoil and seed the area according to the seed schedule on the reclamation landscape plan map. <br />This area will be graded consistent with existing (pre-mining conditions). <br />6. Varied Setbacks: The setback locations vary based on the proximity of permanent structures and <br />the depth of the resource. The setbacks are measured from the structure or property line to the toe <br />of the slope (refer to the typical topsoil stockpile at edge of mining areas cross section). The <br />mining setbacks and reclamation setbacks are different. Please refer to the mining plan map and <br />reclamation plan map for the specific setbacks. <br />7. Trees and Shrubs along Highway: Per our discussion, we have added the following note to the <br />mining plan map and the mining landscape plan, "All trees along State Highway 85 shall be planted <br />on SW TKO Joint Venture property so that the dripline of the trees does not extend into CDOT <br />right-of-way at maturity. <br />8. Reclamation Plan: Please refer to the reclamation plan map for the proposed reclamation plan that <br />includes a 82.5-acre pond and a 175-acre pond. The remaining land will be reclaimed as upland <br />pastureland. <br />9. Using Claystone for the Liner: I hope that our meeting at Lafarge's Dunes operation has helped to <br />allay your concerns about mining the claystone and utilizing it as the material fro the clay lining in <br />the ponds. <br />10. Danger of Long-Term Steep Slopes: The operator will mine the site in 20-acre sections, as <br />depicted on the Mining Plan Map (Attachment 3). Reclamation will begin at the end of each mining <br />sequence. However, it is likely that a different entity will be constructing the compacted clay slope <br />liners that form the water storage reservoirs. In order to construct the reservoir in the most efficient <br />manner (and thus the fastest and most cost-effective manner}, fhe applicant must limit the number <br />of mobilizations and inter-clay liner joints (traverse slopes within the liner). It will likely take the <br />contractor two months to construct 1,000 feet of slope liner. Thus, the contractor will need about <br />40 acres of mined area to efficiently reclaim the previously mined area with a compacted clay liner. <br />We understand CDOTs concern that the entire site could be disturbed. As a result, we request the <br />following permit conditions: <br />a. The site shall be mined in 20-25-acre sections as depicted on the Mining Plan Map. <br />b. The site shall be mined and reclaimed concurrently. The miner shall restore the top of the <br />mining phase to reclamation condition as soon as mining is completed in a phase. <br />c. The operator may not mine Pond 2 below groundwater until Pond 1 is reclaimed to above the <br />groundwater level. <br />d. The applicant must begin constructing the slope liner after two phases have been completely <br />mined to bedrock by the miner. <br />e. The maximum linear feet of slope liner that may be disturbed at any given time will be 6,000 <br />lineal feet. <br />11. Information on ConsWction of Clay Liner: Following is a general discussion of the construction of <br />the clay liner, similar to the discussion that we had at the Dunes operation. Please note that the <br />State Engineer will be reviewing and approving the reservoir design as will the Division of Minerals <br />and Geology. <br />
