• estimated to be at least 6". Table D-94 lists the area <br />covered and the volume of topsoil distributed assuming the 6". <br />The material from pile 6 was moved with a front end loader and <br />the material from pile 5 was moved using scrapers. The <br />material was spread using a dozer or track hoe. This topsoil <br />placement took place in May and June 1994 while subsoil was <br />being placed elsewhere on the pile. The Topsoil Piles Nos. 5 <br />and 6 were depleted during this cover project, approximatedly <br />6" of topsoil was redistributed on these areas and straw bales <br />were placed around the disturbed area for drainage control. <br />CRDA 2 benches 1 and 2. The topsoil placed on these benches <br />came from Topsoil Piles No. 7. The average thickness was not <br />detectable during final soil depth sampling but was estimated <br />to be at least 6". No topsoil was placed on the road. Table <br />D-94 lists the area covered and the volume of topsoil <br />distributed assuming the 6". The material was moved using <br />scrapers and was placed on the slope with scrapers, a dozer or <br />a track hoe. The placement of this topsoil took place in June <br />1994. A berm was maintained for drainage control around the <br />portions of the topsoil pile removed. <br />CRDA 2 benches 3 and part of 4. The topsoil place on these <br />benches came from topsoil Pile No. 7. The average thickness <br />was not detectable during final soil depth sampling but was <br />• estimated of be at least 6". Table D-94 lists the area <br />covered and the volume of topsoil distributed assuming the 6". <br />The material was moved using 10 wheel dump trucks and was <br />spread on the benches using a dozer or a track hoe. The <br />placement of this topsoil took place in August and September <br />1994. A small amount of topsoil is still available at <br />Topsoil Pile No. 7. <br />Table D-94 <br />Location Area Thickness Volume <br />CRDA 1, Benches 1-3 9.5 acres 0.5' 7,660 CY <br />CRDA 2, Benches 1&2 4.2 0.5 3,390 <br />CRDA 2, Road 1.0 0.0 0 <br />CRDA 2, Benches 3&4 3.0' 0.5 2,420 <br />Total 17.7 13,470 <br />(B) Area Seeded - Seeding was done on areas covered and areas <br />where material was removed. Due to OSM's concern for <br />contemporaneous reclamation, seeding was done in July 1994 on <br />the areas covered and most of the areas where material was <br />• removed during work in May through July. The hydroseeded <br />areas had Kiwi Green applied with the seed at a rate of 25 <br />
