• FUNCTIOIJ DESCRIPTION SUMMARY <br />Backfilling the portal face-up area requires the use of a one cubic yard <br />capacity backhoe to pull the bench material on to the portal bench. <br />Grading is completed by a Caterpillar 12G motor grader. This final <br />grading function restores the disturbed areas to the contour shown on <br />the Post-Mining Topography Map (Map 2). <br />Ripping the regraded surface is completed by a Caterpillar 12G motor <br />grader equipped with scarifier ripper. This function roughens the <br />graded surface prior to soil replacement, increases infiltrations and <br />provides a surface which the soil material will bond. <br />Topsoil replacement is completed by loading and hauling the topsoil <br />stockpile to the regraded areas by a Caterpillar 6Z 16 scraper. The <br />• scraper will spread the topsoil on the graded and scarified surface. <br />Seedbed preparation includes chisel plowing, discing, and/or harrowing <br />the area on which the topsoil has been placed prior to seeding and <br />planting. <br />Mulching and Anchoring Straw mulch will be applied by hand or a mulch <br />blower. Crimping will be accomplished with a disc or mulch crimper. <br />Netting will be accomplished by hand and will be fastened with staples. <br />Crimping and netting will be completed where required to ensure that the <br />mulch material is stabilized until a vegetation is well established. <br />Seeding and planting includes the cost of seed and plants, and the cost <br />for planting, drill seeding, broadcast seeding, or woody stock planting <br />as required. <br />n <br />LJ <br />
