i4.4.2.3 Final Reclamation <br />Topsoil Removal. Storage and Distribution <br />The refuse pile was reclaimed in 1986. The work consisted of regrading the top bench <br />of refuse to establish a suitable final subgrade, covering all exposed refuse with 4 -feet <br />of cover, extinguishing an old fire west of the pile, establishing a rip rapped channel <br />and seeding. <br />Approximately 2,000 cubic yards of topsoil had been stockpiled at the refuse pile. <br />Since the volume of available topsoil was insufficient to cover the entire disposal area, <br />other soil material was imported to the pile from the No. 1 Mine site area. <br />The topsoil that had been salvaged for the refuse pile was distributed over the <br />reclaimed area. Both the topsoil and the imported material was distributed to a <br />minimum depth of 6 inches. The operator did not keep track of where the topsoil was <br />placed so all of the material was treated as plant growth media that would have to be <br />amended. <br />• The following volume estimates were made for the amounts of fill and soil cover <br />required to reclaim the refuse disposal site, in addition to the topsoil available for <br />stockpiling from the site itself: <br />86,000 cubic yards of fill <br />10,000 cubic yards of soil cover <br />Layers of the fill and soil cover were scarified at the surface before applying the <br />subsequent layers, in order to hold the slope better and to prevent saturated zones. <br />Terrace design and final surface configuration are indicated on the design drawings <br />and reclamation maps (Drawings D-4-15, D-4-16, D-4-19 and D-4-20. <br />The soils were analyzed for suitability as plant growth media and found to be suitable <br />with the addition of certain amendments. The soils report dated August 28, 1986 is <br />.presented in Appendix 3-S. <br />'r Ci <br />4-46 <br />11-99 <br />
