I <br />RECLAMATION PLAN <br />EXHIBIT E <br />I <br />I <br />1 <br />The proposed reclamation of the Winkler Quarry will be for <br />rangeland as it is currently being utilized. The net result of <br />mining will be to lower the top of the mesa from 10 to 20 feet. <br />The net effect of this lowering will be barely visible to the <br />surrounding area. Mining will not be done at the edge of the <br />upland. A 3:1 horizontal:vertical slope down into the pit <br />setback from the edge of the mesa will leave the visual <br />impression that the upland has been untouched. <br />Reclamation will be done concurrently with the mining operation. <br />Backfilling with overburden and topsoil will begin as each mining <br />phase is completed. Final grading and shaping of slopes will be <br />done immediately. Reseeding will be done either in early spring, <br />or late fall to allow maximum germination of the seed mix. A <br />second reseeding will be done one year later on areas where <br />seeding has failed to take hold. <br />Overburden and topsoil will be stockpiled separately. <br />' Erosion control will be a very important part of reclamation work <br />throughout the life of the operation, affecting water quality, <br />soil quality, revegetation, grading, and slope stability. <br />' Following is a list of reclamation and erosion control techniques <br />available for use: <br />i <br />Contour Ridging <br />This technique employs a plow or disk to create a series of <br />trenches running perpendicular to the slope. The trenches reduce <br />slope length by catching and holding water, thus allowing it to <br />percolate into the slope. Spacing between the trenches and <br />trench depth depends on the form of equipment used. Wind erosion <br />can also be reduced by contour plowing. The moisture holding <br />capabilities of the ridging encourages seed germination. <br />Diversion Terrace <br />A diversion terrace is a channel with a supporting ridge on the <br />lower side constructed across the slope. It is used to reduce <br />slope lengths, break up concentrations of runoff, and to move <br />water to stable outlets at a non - erosive velocity. Channel <br />grades may be variable, with the allowable velocity for the soil <br />type and vegetative cover determining maximum grade. Maximum <br />channel side slopes for temporary diversion are 1:1 and 3:1 for <br />permanent ones. <br />E -1 <br />
