Ms. Erica Crosby, Division of Minerals and Geology <br />March 23, 2005 ~~ <br />Page 5 <br />CIVIL RESOURCES, LLC <br />11. Please state the total area of land to be affected (in total) compared with the permitted area of <br />361 acres. <br />We will forward the total area of affected land to you in the near future, with the reclamation <br />cost estimate. <br />The operator will mine the site in 20-acre sections, as depicted on the Mining Plan Map <br />(Attachment 3). Reclamation will begin at the end of each mining sequence. However, it is <br />likely that a different entity will be constructing the compacted clay slope liners that form the <br />water storage reservoirs. In order to construct the reservoir in the most efficient manner (and <br />thus the fastest and most cost-effective manner), the applicant must limit the number of <br />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 (iner. Thus, the contractor will need <br />about 40 acres of mined area to efficiently reclaim the previously mined area with a <br />compacted clay liner. <br />We understand the Division's concern that the entire site could be disturbed. As a result, we <br />request the 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 <br />the 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 <br />above the groundwater level. <br />d. The applicant must begin constructing the slope liner after two phases have been <br />completely mined to bedrock by the miner. <br />e. The maximum linear feet of slope (iner that may be disturbed at any given time will be <br />lineal feet. (We will forward this number with the reclamation cost estimate.) <br />12. Exhibit 3 of 7 depicts two temporary 4' high berms along the perimeter of areas 3 and 6. <br />Please identify if these piles are topsoil or overburden material on the exhibit. <br />The two temporary 4' high berms along the perimeter of areas 3 and 6 will be comprised of <br />topsoil. <br />13. In Exhibit D of the application, the applicant states that overburden will be stripped and <br />stockpiled to the south as mining proceeds from north to south. On map 3 of 7 it is stated <br />that "...topsoil and overburden will be segregated and stockpiled around the perimeter of the <br />mining area" and "temporary stockpiles vary in locations and size within each phase." Please <br />depict on the exhibits a!! topsoil and overburden piles that wiAbe stored on site and used for <br />reclamation. Topsoil will need to be segregated and stored separately from the overburden <br />material as required by Rule 3.1.9(1). <br />Refer to the Mining Plan Map (Attachment 3) for the locations of topsoil stockpiles and <br />temporary overburden stockpiles. Please note that the operator will not use any overburden <br />for reclamation. All overburden and excess topsoil will be sold throughout the mining <br />process. The slope liner will be derived from claystone bedrock. <br />
