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 soils in the area will be analyzed to establish quality. <br /> (ii) The access roads and facilities area 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, discing, raking or scarifying 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 necessary. <br /> (iii) The U.S. Department of Agriculture Soil Conservation Service provided the <br /> following recommendations regarding seed type and quantities: <br /> (1) (2) (3) (4) (5) (6) <br /> PLS Seed Total PLS <br /> Required Percent of Rate Per Species Bulk <br /> PLS Rates Species in Species/Acre Planned Planned Seed <br /> /Acre Mixture (1) x(2) Acres (3) x(4) Estimate <br /> Pubescent Wheatgrass 14 30 4.2 1 4.2 5 Ib. <br /> Western Wheatgrass 16 30 4.8 1 4.8 5.5 lb. <br /> Smooth Brome 13 30 3.9 1 3.9 4.5 Ib. <br /> Yellow Sweet Clover 7 10 0.7 1 0.7 1 Ib. <br /> Note: PLS is Pure Live Seed. Percent PLS is determined by germination percent multiplied by seed purity percent. This <br /> information is obtained from the seed tag. The amount in column 5 should be divided by the percent PLS to determine the <br /> pounds of bulk seed to purchase. If acreage changes,then total seed amount will change proportionately. <br /> (iv) The seed should be drilled into the topsoil area. If seed is not drilled, all <br /> rates shall be doubled. If the seedbed has not been adequately roughened prior to seeding, the <br /> seed shall be raked or harrowed after broadcast application. <br /> (v) The mulch applied shall be 4000 pounds of grass/hay per acre with an <br /> effective crimping method applied. <br /> (vi) Shrubs will be planted from container stock or transplanted or started from <br /> root cuttings from wild stock in the immediate area. Trees are planned to be planted from <br /> seedling,tubling, or transplanted from the site. The planned species of shrubs are those <br /> consistent with the area such as Oregon grape, cinquefoil, current, rose, mountain snowberry, <br /> and Rocky Mountain maple. The planned species of trees are those consistent with the area such <br /> as spruce, fu-t, pine, and aspen. Shrubs and trees will be planted randomly in the revegetated <br /> 20 <br />
