substitute. Several species contained in Table 11-1 are not currently found on site according <br />to the baseline data included for the area. However, all the species listed in table 11-2 are <br />found on the site area currently. What criterion will determine when the second seed mix <br />will be used? Why is Sheep fescue used as opposed to Arizona fescue? What is the seeding <br />rate for Cicer milkvetch? This plant is very competitive and it is a useful legume for adding <br />nitrogen to the soil, however, if too much is planted, it may out-compete the other <br />vegetation. CC&V should provide a list of pounds of pure live seed per acre. The quantity <br />of each species should be representative of the current plant species for the site. <br />G. What is the criterion that CC&V will utilize to determine which "steep slopes" will be <br />hydro mulched? Please explain. <br />H. The East Cresson Overburden storage area is expected to be end dumped at 50 foot lifts, <br />compacted with rubber tired vehicles, and capped with 3 feet of low infiltration cover. In <br />portions of the application this low infiltration cover is referred to as a clay cap. The <br />Division will require this low infiltration cover to be placed in accordance with the <br />specification for the soil liner fill, for the valley leach facility. In time roots of the established <br />community may pierce through this low infiltration cover. This could impact the long term <br />success of the plant species establishment. A lime amendment to lower the possibility of <br />acidic environment impeding the growth will be required. Please provide the amount of <br />lime per ton of overburden that will be utilized to ensure the success of the cover. <br />1. The operator plans to transplant aspen trees in the North Cresson Mine area view shed. <br />How many acres of the reclaimed North Cresson view shed will be planted with aspen? In <br />order to complete this planting CC&V plans to extract mature aspen trees using front end <br />loaders and plant them in "pads". These pads of aspen will be planted on the re-graded <br />slopes. Include in your discussions a site preparation plan and how the aspens will be <br />planted on these sites, including recipient slope preparations and reclamation of the pad <br />removal areas. CC&V has included in the detailed financial warranty calculation, a <br />commitment for irrigate these pads for two years using a water truck and a laborer. Given <br />the difficult slopes of the area, DRMS recommends CC&V utilize the same drip irrigation <br />system used in the valley leach facility to deliver the water. CC&V already has the <br />infrastructure for such a system. Please provide a drip irrigation design as recommended <br />and adjust the warranty accordingly. <br />J. The DRMS expects CC&V, to continue their noxious weed control plan as approved. <br />DRMS, has never observed a noxious weed infestation on site, and expects that practice to <br />continue. Animal browsing may significantly impact the success of establishing a stand of <br />aspen. It is recommended that a fence be built around the area to help exclude browsing <br />animals. <br />K. As stated under the mining plan, DRMS recommends CC&V completely backfill the North <br />Cresson area to original contour, in part to limit infiltration of surface water expressing as <br />shallow ground water through the exposed high wall fractures and fissures which could <br />adversely impact the long term hydrologic balance. <br />VI) Exhibit G- Water Information-Rule 6.4.7 <br />A. The Division recommends calculating net-acid generation potential for the waste-rock <br />through time, so that not only spatial but temporal variations in the geochemical makeup of <br />7
