RN07 <br />Page 16 <br />5/30/18 <br /> <br />f. Please submit to DRMS any updated design, as built drawings and SedCad results that <br />pertain to bringing Section 2. 05. 3 up to date to accurately reflect the infrastructure that is <br />" on the ground" at Foidel. <br /> <br /> <br />2.05.4 – Reclamation Plan <br />45. Section 2.05.4(2)(C) portal area section indicates that the design details for upland diversions depicted on Map <br />25 are located in Exhibit 8-R. It appears these designs are located in Exhibit 8N. Please revise this page <br />accordingly. <br /> <br />Response: - The referenced permit text sections have been reviewed and any erroneous references corrected. <br />Copies of any revised text pages accompany these responses for replacement in the PAP. <br /> <br />Resolved <br /> <br />46. Map 31, Post-Mining Topography Map only depicts the postmine topography of the main portal/facilities area. <br />Rule 2.05.4(2)(C) requires a postmining contour map and appropriate cross-sections that are typical and <br />representative of the anticipated character of the final surface configuration of the proposed permit area. <br />Please provide postmining contour maps that depict the postmine configurations of all of the surface disturbed <br />areas. <br /> <br />Response: - Facilities disturbances outside of the main portal/facilities area are generally pad areas, which are <br />limited in size and do not vary significantly from the original terrain. At each of these locations, the pads have been <br />constructed using cut/fill construction methods, with no imported or exported material . Reclamation will involve <br />regrading the existing material to blend with the surrounding terrain and promote effective site drainage. To date <br />and given these considerations, the CDRMS has not required detailed postmining configuration drawings or cross- <br />sections for these limited disturbance activities. For reference, design drawings reflecting cut/fill construction and <br />by direct reference, the reverse action of regrading, are provided for the following outlying facilities areas; 5MN <br />Cement Borehole (MR14-283, Ex 49AA); 16LT Utility Borehole (TR11-78, Ex 49Z); 18LT Ventilation Shaft <br />Installation (TR06-66, Ex 49R); 6MN Mine Water Storage Reservoir (TR07-61, Ex 49O); 6MN Ventilation Shaft <br />Installation (TR05-48, Ex 49A); 18RT Intake Shaft (TR04-44, Reclaimed). <br /> <br />Resoloved <br /> <br />47. Page 2.05-108 indicates the depth of topsoil placement is shown on Map 29. This information is not depicted <br />on Map 29. Please update Map 29 to depict the depth topsoil will be placed over the reclaimed areas. <br /> <br />Response: - As discussed in the previous response to Comment 36, soil depths can be highly variable, depending <br />on a number of factors. The reality of soil removal/replacement operations in the field, is that TC attempts to <br />recover all reasonably available and suitable soil material from new disturbance areas, and places these materials in <br />stockpile for later replacement during the reclamation process. Soil replacement operations and depths are, <br />therefore, limited to the stockpiled soil materials that are available. Table 49a, Topsoil Stockpile Summary, <br />identifies soil stockpile designations and corresponding volumes. Generally, if the stockpiled soil materials are <br />associated with a specific disturbance area, all available stockpiled material will be replaced on that area, with <br />reasonable efforts to replace the soils at a uniform thickness. Where there are multiple stockpiles associated with a <br />larger disturbance area (ie: the Mine Facilities Area), the overall stockpiled soil material volume will be allocated
