OPliRA'PIOd PLAri • <br />The Ciruela Canyou processing waste pile will have a final design <br />capacity of 101,000 cy. Tire total surface area of the pile has be err <br />estimated to be 4.yo acres. There is "29,070 cy of existing processing <br />waste. hstirnated proauction from the Golden Cagle Kline is b0U,000 tpy for <br />the permit term. Approximately .02 cy of processing wastes are produced per <br />ton of production yielding 1b;000 cy of processing waste per year. Tne pile <br />life is expected to oe 4.5 years. <br />Initial site construction xill be to establish drainage as shown on <br />Figure 7. Topsoil will be stripped from Areas 1 (nearest to Golden Eagle <br />slope entry), 2 and 3. Topsoil will be placed in the topsoil pile and <br />staoilized. <br />The existing pile will then be pushed and/or hauled for construction of <br />the first bench (contour 7120'). Prior to the pile reaching the 7140' <br />bench, topsoil and subsoil will be removed from Area 1 (nearest to the . <br />proposed topsoil pile). As pile development reaches successive benches, <br />subsoil will be removed from Area 1 (nearest to Golden Eagle slope entry] <br />and Area 4. <br />In these instances, coal processing waste will oe pushed over subsoil <br />prior to subsoil removal. WFC will make every effort to push processing <br />xaste off subsoil pr: •r to salvaging and stockpiling or immediate <br />redistribution. A 25 ft Duffer will be maintained between undisturoed cuts <br />and coal processing waste. <br />Folloxing is a summary of cut volumes to reclaim the pile. <br />Topsoil and Subsoil Volumes <br />Area Area (ft2) Salvsge Depth (ft) Total (yd3) <br />1 ti0,d0U rs.d3 1y,dd4 <br />~ 55,200 0.50 ~,~22 <br />3 72,uoo ~.o0 2;ao7 <br />4 24,000 d.-5 7,d4z9 <br />2 j1'So2 yd3 <br />Volume required = 4.9o acres x v ft x 43,5tiU ft /acre x 1 yd /27 ft = . <br />32,OOd yd <br />-t7- <br />
