Approximately 916,500 bank yd' of overburden and 252,500 bank yd' of washed fines <br />will result from the land remaining to be mined. <br />The following table provides an estimate of the material necessary for the reclamation <br />plan: <br />Reclamation Requirement Quantity (loose <br />yds) <br />^ Backfill slopes (1:1 to 3:1) 420,000 <br />Site-wide final grading 250,000 <br />Cover existing impoundment areas 150,000 <br />Construct future impoundment area <br />includin interior cell berms 280,000 <br />• Cover future impoundment area 100,000 <br />Total 1,200,000 yd <br />Approximately 1.2M loose yd3 of material are required to implement the reclamation <br />plan. However, 0.91 M bank yd3 of overburden are available for use in reclamation. <br />Applying a swell factor of 25% to the bank overburden volume results in approximately <br />1.13M loose yd' of overburden available for reclamation. The small deficit can be made <br />up with screened fines. This is a more than adequate volume of material on site to <br />implement the reclamation plan shown in this Technical Revision. Screened fines not <br />used in reclamation will be sold off-site. Products not sold can be used in the final <br />reclamation of the plant site area. <br />This Technical Revision pertains only to the western Spicer and McKay leases (E'/z <br />SW'/< and W'/z S'/< of Section 4, and portions of Section 9) and not to the area to the <br />east know as the Spicer Extension. The Spicer Extension will remain (and is shown on <br />the accompanying maps) just as it is currently permitted. <br />
