! I r <br /> a) Top soil will be removed to a depth of 6 to 12 inches and placed on the north side of the <br /> area to be excavated, in na berm running the length of the pit and approximately 4 feet <br /> tall. <br /> b) The excavation will not be greater than 3:1 slopes, nor will the berm have greater than <br /> 3:1 slopes. <br /> c) When the excavation has been completed, top soil will be replaced to a depth of at least 6 <br /> inches and revegetated according to NRCS recommendations herewith. <br /> i. The site will be seeded immediately after mining has been completed. but in such a <br /> way that germinated seed will have time to grow prior to freezing weather, The seed <br /> bed will be disced and harrowed to eliminate compacted conditions. <br /> ii. The seed mixture will specified by the NRCS and is expected to be readily available <br /> in quantity from Arkansas Valley Seed Company as typical reclamation mix for the <br /> dry areas of the San Luis Valley. A mixture is enclosed with Exhibit D <br /> iii. The seed mixture will be broadcast with a utility vehicle towing a PTO(power take- <br /> off) driven broadcaster. <br /> iv. The mulch-seed mixture will be crimped into the soil with grousers on the tracks of a <br /> small dozer. <br /> N. We expect to establish small trees as recommended by the NRCS, probably the type <br /> used for windbreaks that will be planted with gel bags during the early spring months <br /> or early fall. Since water will be available, a drip irrigation system will be established. <br /> Probably not more than 20 trees per acre will be planted on the berm area. If this <br /> creates a shortfall of topsoil for reestablishment of soil on the pit slopes,crusher fines <br /> will be used to attain depth sufficient for establishment of grasses and forbs. <br /> vi. No ponds will be excavated for this operation. <br /> Summit engineering Job Number: 240328CE 196 <br /> 719-589-6147 <br /> ` ' Alamosa, CO <br />
