The <br />cost estimate below assrunes transport of topsoil)zom the Carbondale azea. However, if Sierra is <br />able to recover topsoil from the areas to be covered by the waste piles, such as south of the <br />existing waste piles, this material will be sufficient to satisfy the reclamation requirement. The <br />total area to be revegetated is estimated at approximately 14,000 square feet or about 1 /3 acre. <br />No major additions to the existing roads arc planned by Siena other than to extend access to <br />waste piles. 1'he total area to be revegetated is not anticipated to exceed 1/3 acre over any part of <br />the operating life of the quarry, <br />(i) The depth of soil is planned to be six inches, comparable with the sparse soda in <br />the area. Samples of soils in the area will be analyzed to establish quality. <br />(ii) The access roads and facilities azea will be active throughout the life of <br />operations, so topsoil placement and revegetation will occur only after mining is complete. Seed <br />beds for the grass and forb mix will be prepared by ripping, diseing, raking or scarifying of any <br />compacted areas to approximately 6 inches, followed by placement of topsoil, the soil left rough <br />Fertiliration will be based on the identified needs of the soils placed for revegetation. Since the <br />soruce of the imported soils is not specifically identified, fertilization requirements cannot be <br />established at this time. Only minimal fertilization is planned however during establishment of <br />the grass mix in order to minimize any eft'ects on water quality in the area, and then only where <br />soil tests iadicate nutrient deficiencies for the plant species to be established. Ongoing <br />fertilization is not considered appropriate for creating self-sustaining vegetative growth. No <br />more than oue or two fertilizer applications would, in any rase, be expected to be necessary. <br />(iii} The U.S. Department ofAgriculture Soil Conservation Service provided the <br />following recommendations (except Cicer MiUcvctch has been substituted for Yetlow Sweet <br />Clover on the recommendation of CDMG) regazdnng seed type and quantities: <br /> (I) (2) (3) (4) (5) (6) <br /> PLS Seed Total PLS <br /> Requited Percent of Rate Per Specie Bulk <br /> PLS Rale9 Species in Beetles/Acre Planned Planned Seed <br /> /9u9 Mixture (11 x t21 cr (~,~,(4) E~IlnilD <br />Pubescent Wheatgrass 14 30 a.2 1 4.2 5 Ib. <br />Western Wheatgrass 16 30 4,8 1 4.8 5.5 Ib. <br />Smooth Brome 13 30 3.9 1 3.9 4.5 Ib. <br />Cicer Milkvetch 7 10 0,1 1 0.1 1 Ib. <br />Note: PLS Is Pure Live Seed.
