• 2.05.3(5) Topsoil <br />Topsoil as used in this application will be defined to be the "A" soil horizon. From the <br />soils information Section 2.04.9, it has been determined that topsoil is either scarce, <br />non-existent or difficult to salvage in a major portion of the azea to be disturbed by <br />mining. Results of chemical analyses indicate that horizon "B" and "C" offer suitable <br />revegetation potential, particularly in Falfa clay loam, 3 to 8 percent slopes. The basic <br />soil salvage plan is to retrieve all existing, suitable soil in areas where retrieval is <br />practicable and make up deficiencies from disturbed areas occurring on the Falfa clay <br />loam soil. <br />The delineation of stripping areas and depths are shown on Map 5-3 and Table 5-2 <br />indicating soil balance numerics. Existing stockpile locations are shown on Map 5-7; <br />approximate dimensions are shown on Table 5-3. <br />The operational aspects of soil stripping and respreading occur in the following order. <br />Initially, trees and lazge shrubs are grubbed and removed from the area. Next suitable <br />soil materials are salvaged and either stockpiled or returned to an area ready for re- <br />topsoiling. After respreading, the replaced soil materials aze seeded and mulched. <br />Topsoil will be returned to the reclaimed azea as per the specifications shown on Map <br />• 5-3 (Soils Stripping and Respreading). Specifically, azeas which were formerly in <br />agricultural production will have 12" of soil replaced which is equal to the amount of <br />topsoil salvaged from those azeas. The canyon area will have 18" of soil redistributed <br />during reclamation which represents the average of topsoil depths salvaged (0"-36"). <br />The soil stockpiles have been seeded with the following seed mix: <br />Species <br />Slender Wheatgrass <br />Western Wheatgrass <br />Thickspike Wheatgrass <br />Crested Wheatgrass <br />Perennial Rye Grass <br />Cicer Milkvetch <br />Utah Sweetvetch <br />Total Seed Rate <br />C~ <br />lbs./acre <br />10.0 <br />10.0 <br />10.0 <br />3.0 <br />3.0 <br />1.0 <br />10 <br />38.0 <br />Technical Revision 08 (v 1.3) 5-13 Revised 9/1997 <br />
