<br />impact any area where CYMC may leave caused a violation of its permit. Also, no fines will be <br />placed on the waste piles until an effective sediment control structure is established. Once a <br />suitable sediment control structure is established, Sierra will begin to deposit waste near the <br />north end ofthe waste pile atra just above the sediment control structure. Access to this area <br />will be off the south end of the existing easterly waste pile road, then down an existing atp hwaX <br />tote-extst+xgyee@~il. The waste pile will be built up from this area, according to the contours <br />shown on tbe Post Reclamation Contours map. The average final slope will be no greater than <br />2:1. <br />(cl Reveeetation: Because the original vegetation in the western portions of the affected <br />azea is spazse to nonexistent, and because the Marble Historical Society has requested that the <br />mazble waste piles remain exposed, only limited revegetation is anticipated by Sierra <br />Revegetation will involve placement of topsoil on existing access roads and facilities areas. The <br />cost estimate below assumes transport of topsoil from 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 existitg roads are planned by Sierra other than to extend access to <br />waste piles. The 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 soils in <br />the area. Samples of soi]s in the area will be analyzed to establish quality. <br />(ri) The access roads and facilities area will be active throughout the life of <br />operations, so topsoil placement and revegetation will occur only after mit»ng is complete. Seed <br />beds for the grass and forb mix will be prepazed by ripping, dieting, raking or scazifying of any <br />compacted areas to approximately 6 inches, followed by placement of topsoil, the soil left rough. <br />Fertilization will be based on the identified needs of the soils placed for revegetation. Since the <br />source 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 effects on water quality in the area, and then only where <br />soil tests indicate 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 one or two fertilizer applications would, in any case, be expected to be ttecessary. <br />(iii) The U.S. Department of,4griculture Soil Conservation Service provided the <br />following recommendations (except Cicer Milkvetch has been substituted for Yellow Sweet <br />Clover on the recommendation of CDMG) regarding seed type and quamities: <br />25 <br />
