1 <br /> Response to DRMS Adequacy Review-Cotter JD-8 Mine Reclamation Plan Amendment <br /> the ventholes plugged permanently. This cover material will be slightly mounded so that <br /> after natural compaction there will not be a depression remaining to collect any surface <br /> water. This area will then be scarified and seeded. <br /> The soil cover material in the areas of the proposed vent holes will be salvaged, and <br /> stored adjacent to the vent hole areas, and seeded to reduce erosion potential. <br /> Access roads to the ventholes will have water bars constructed as necessary to minimize <br /> the potential for erosion, and then will be scarified and seeded, and then closed to <br /> vehicular access unless DOE wants them left open. <br /> Power lines to the mine portal and ventholes will be supplied by San Miguel Power <br /> Association(SMPA). SMPA will be responsible for the initial installation to supply the <br /> power lines, and the final removal of the power lines after Cotter Corporation does not <br /> require power to the mine facilities. <br /> Timing for the placement of seed will be directly following placement of the soil cover <br /> material, prior to the cover material forming a hard crust. Preferably this will he in either <br /> the spring or fall, but experience indicates that getting the seed on the soil cover material <br /> soon after placement of the soil cover material is more important than the time of year the <br /> seed is placed to the success of the seeding effort. A copy of the current DOE seed mix is <br /> attached on the next page. <br /> Page A-15 <br />
