8 . Colowyo provided additional detail on slope roughening practices on amended pages <br />2.05-48 and 2.05-49, as requested by the Division. Item Resolved. <br />9. The Division requested clarification regarding [post -2007] soil replacement plans for the <br />East Pit, Gssard Ldut, and facilities area. Narrative on amended page 2.05 -47 <br />indicates that variable topsoil replacement would apply to both original and South Taylor <br />areas ' " on ridge tops with variably deeper application down slopes to the bottom of <br />coherent drainages"). The variable soil replacement plan as presented seems to be <br />focused on pit and fill disturbance areas. It is not clear how the variable replacement plan <br />would apply to the Gssard Ladout and facility area locations, given the location and <br />landf rms in these facility locations. <br />short paragraph o n page 2.05-47 notes that prior r to 2005, essentially all reclamation <br />units were covered with an average of 18 inches of topsoil, with certain noted exceptions. <br />It is noted in various text sections that the variable topsoil replacement approach initiated <br />with 2008 reclamation. Presumably, all areas reclaimed 1n 2005 through 2007 were <br />subject to " average uniform. replacement thickness requirement, but this should be <br />clarified. <br />Please provide narrative clarification in the text on page 2.05-47 regarding <br />reclamation units (area/year) where the " average uniform replacement thickness <br />applied in the past or would apply in the future, The variable replacement plan <br />would not seem to be applicable to the Gossard Loadout and mine facility areas; <br />please clarify the replacement plan for these locations. <br />10. This item also requested clarification regarding variable vs. uniform thickness <br />replacement areas. Please refer to Item 9 above. <br />
