along the reservoir perimeters to construct the liner and achieve the final grade. Final <br />reclamation by capping with topsoil and re-vegetating above the expected reservoir water level <br />will follow liner constmction operations closely to minimize the amount of disturbance at any <br />one time. <br />Backfilled Pastureland <br />Phase I of the mining operation will be Backfilled to the approximate original grade using <br />overburden and topsoil stockpiled from the Phase I excavation and from lime soil material <br />excavated from the western side of the permit area. Similazly, areas within Phase II will be <br />Backfilled and reclaimed as pastureland (see Reclamation Plan Map, Exhibit F). Backfilling <br />material for Phase I and Phase II will mainly consist of lime soils excavated from the western <br />part of the site. Native overburden and 6 to 12 inches of topsoil will be placed on top of the <br />Backfilled lime soils to provide a growth medium for pasture grasses. Once Backfilling and <br />grading has been completed in an azea, seeding will occur as soon as practicable (based on first <br />available seeding season). <br />Reclamation Measures/Materials Handlin¢ <br />The mining will create the rough outline for the reservoir shorelines and the pastureland (see <br />Reclamation Plan Map, Exhibit F). The Backfilling will be done to provide stabilized shorelines <br />around the reservoirs and general agricultural land use. The reservoir clay liner and side slopes <br />will be created with bedrock claystone and overburden while the reclaimed pastureland will be <br />Backfilled with a combination of native bedrock claystone, lime soils, and overburden. There <br />will not be known toxic or hazardous materials in the backfill material. Additionally, it is not <br />likely that acid forming or toxic materials will be encountered during mining. <br />An abundance of lime soils and overburden is available for the Backfilling and grading of the <br />reclaimed pastureland azeas. The westem half of the site contains 6 to 8 feet of lime soils and <br />overburden that will be used immediately for Backfilling or stockpiled on-site. The lime soils <br />material is from Great Western Sugar Company's abandoned sediment settling azeas. Sediment <br />washed from sugar beets was deposited in these settling basins. The sediment has been tested <br />and is safe for use as inert backfill as demonstrated in the Wagner/Kauffinan Pit #3 original <br />permit documents. <br />Each mining azea will be reclaimed using bedrock claystone, lime soils, overburden, topsoil, and <br />other inert materials from on-site. However, if materials from off-site are used, the applicant will <br />provide the Division with the appropriate notices and affidavit in accordance with Rule 3.1.5(9). <br />The mining will not leave high walls on the property. There will be no auger holes, adits, or <br />shafts left on the property. <br />Topsoiling <br />The top two to six inches of soil on the property is classified as topsoil. This layer includes the <br />root zone of grasses and crops, which will be stripped and stockpiled sepazately.
