same equipment will be used to drive the sampling barrel and <br />3/9-inch well casing for the smaller diameter wells. Well <br />installation procedures have been outlined in the Alluvial <br />Groundwater Characterization plan prepared by Adrian Brown <br />Consultants for the Big Elk Mine. Section 9.3 from this <br />document is included with the NOI. <br />Since excavation will not be required for road construction or <br />drill site preparation, the topsoil will not be removed and <br />replaced. The wells will be installed in late winter/early <br />spring, and wet, soft ground may be encountered. Where wheel <br />rutting occurs, the rutted ground will be smoothed over <br />following completion of well installation work, and a grass <br />seed mixture will be applied as described in item b.(3) below. <br />b. Specifically address: <br />(1) Location and acreage of areas where topsoil will be salvaged and stored; <br />No topsoil will be removed or stockpiled <br />(2) How much earth moving will be needed for new roads or drill sites, if any; <br />Drill pads or access roads will not be constructed, <br />therefore no earthmoving will be required. <br />(3) What seed mix (type and amount) will be used for revegetation; <br />In areas where wheel rutting may occur in soft, wet <br />ground, the rutted ground will be smoothed over <br />following completion of well site work, and a grass seed <br />mixture will be applied. Grass species and quantities <br />are as described below. <br />Smooth Brome 7. 0 lbs/acre <br />Intermediate Wheatgrass 6. 0 lbs/acre <br />Paiute Orchard Grass 2. 0 lbs/acre <br />Alfalfa 2. 0 lbs/acre <br />TOTAL 17, 0 lbs/acre <br />The estimated cost for this seed mixture is 52.00/lb, <br />which yields a per-acre seed cost of $34.00/acre. <br />Estimated re-vegetation areas for the worst case (in <br />which all access approaches and drill sites are rutted) <br />are given in Table 1. Ground smoothing and seed <br />application services are estimated at $50.00/hr. At 2.0 <br />hours of ground smoothing and seed application for each <br />of the 6 sites, it is estimated that the worst case <br />total re-vegetation cost would be a total of $606. <br />4 <br />
