<br /> <br />and equipment out shortly thereafter. It was a couple o_` <br />months later than EFC resumed operation with their own mea <br />and equipment. In attempting to correct the deficiencies <br />left by the contractor, EFC proceeded to level the large <br />spoil dump to the west of the pit and cover the area wit`: <br />topsoil. Leveling of the spoils was done in such a manner <br />that the reclaimed area had a slope similar to those of the <br />surrounding landscape, resulting in the approximate original <br />contour. Spoils in the area under consideration were gr e ed <br />to a smooth at~ci almost .flat topography to increase their . <br />accessibility to livestoc}; following the completion of <br />mining and to assure that runoff rras minimized and that en- <br />site moisture infiltration was increased. <br />2. Topsoiling <br />Following the completion of final grading, stoc}s- <br />piled topsoil and topsoil being removed from the advanci-g .' <br />mitre was reapplied with scrapers until approximately 12 <br />inches of topsoil had been achieved. .Since the final sccil <br />grading eras done with crawler tractors, a'fairly rough <br />boundary existed between the topsoil and leveled spoil. ?'he <br />approximate depth of reapplied topsoil was 12 inches, wish <br />subsoil being applied to even greater depths in certain <br />locations. The topsoil that was stockpiled was in storace <br />for approximately 8 to 10 months prior to reapplication. <br />The soil series covering this site prior to mining <br />were evaluated by the Soil Conservation Service for their <br />suitability for use as topsoil. The Abor Silty Clay Lo a-_ <br />covered the majority of the site and was ranked poor as a <br />topsoil. Absher Very Fine Sandy Loam was next in abundance <br />and was also ranked poor as a topsoil. Only minor portions <br />of Splitro Loam and Buckley Silty Clay Loam were found c~ <br />the site and their potential useage for topsoil was classed <br />as good and unsuited, respectively. Potential suitabili`y <br />of these series for seeding, grasses and legumes was lisped <br />as good, poor, poor and fair, respectively. <br />Final leveling of the topsoil was done by a <br />motorgrader to achieve a uniform seedbed prior to reseeding <br />3. Revegetation <br />Once the grading of the topsoil was completed, <br />the area was seeded to a mixture of plants that were reported <br />by University and Federal agencies as being adapted to t~is <br />
