10.) Please commit to re- spreading all the topsoil over the required areas salvaged <br />during the mining operation. All topsoil available at the site must be salvaged and re- <br />spread for reclamation. <br />11.) Page E -3 of the reclamation plan indicates how the mine slopes around the ground <br />water ponds will be graded, however it does not indicate what the horizontal to vertical <br />ratio will be for the reclaimed pit slopes for the "upland" and "wetland" areas. Please <br />indicate how the side slopes will be graded for the "upland" areas and the "wetland" <br />areas. <br />12.) The mining plan indicates the existing ground water level is 5 -15 feet below the <br />natural ground level. Many of the reclaimed "upland" pit floors are about 20 -25 feet <br />below the pre- mining elevation. Given the bottom of these upland basins will be below <br />the reported ground water level it would appear these excavations would become <br />ground water ponds, not upland areas. Please clarify. <br />13.) It states on Page E -3 of the reclamation plan Lafarge will concurrently reclaim mine <br />walls where mining has been completed according to the phases outline in the Mining <br />Plan. Please provide more detail as to when reclamation will begin for each phase of <br />the operation, prior to initiating mining in the next phase. For example, will the <br />Operator completely mine Phase 113 and 1C with nearly vertical highwalls without <br />initiating reclamation until both phases are mined completely? Or, will re- grading, top - <br />soiling, and seeding be initiated once the disturbed area reaches a certain size and the <br />highwall a certain length? If so, please indicate those amounts. <br />14.) In order to calculate the Financial Warranty, what will be the maximum length of <br />the highwall at any given time during the mining operation? <br />15.) For the upland areas, will mulch be applied to the graded and topsoiled surfaces? If <br />so, how many tons per acre will be applied and will the mulch be secured to the soil <br />through crimping or other methods? Weed free straw mulch crimped into the soil helps <br />stabilize the soils from wind and water erosion, and also provides cover for the newly <br />planted seeds. <br />6.4.6 EXHIBIT F — Reclamation Plan Map <br />16.) On the Reclamation Plan Maps, there are several berms left in place. One is <br />adjacent to the Phase 2 open water pond, and another is located north of the Phase 2 <br />pond adjacent to the location of Overburden Stockpile A as depicted on the mining plan <br />map. It appears these stockpiles will be constructed with topsoil. According to the <br />Mining Plan (Page D3), no permanent stockpiles will be located at the site. Also, all the <br />topsoil salvaged during the mining process must be re- spread over designated disturbed <br />areas for reclamation. These "berms" should not exist at the end of reclamation, please <br />remove them from the reclamation plan map. <br />
