Twentymi(e Cool Company - Foidel Creek Mine, TR04-44 TA Responses 8//2/2004 <br />topsoil pile in the vicinity ofthe pad to contain 5.402 cubic vards ifTwentvmile is to store <br />roadwav topsoil at the pad, or1.452 cubic vards at the~d and 3.950 cubic vards in <br />storage piles along the road. If used, windrows need to be protected as topsoil storage <br />piles. Placement of topsoil storage piles along the road reduces haul costs associated with <br />reclamation. <br />Response: As both a construction and reclamation consideration, TCC plans to stockpile <br />topsoil recovered from the pad azea within the road corridor adjacent to the pad (1,452 cy). <br />Topsoil recovered from the road corridor (3,950 cy) will be windrowed along the southern <br />and eastern edge of the road, to be pulled back over the road disturbance azea during <br />reclamation. All topsoil stockpiles and windrows will be protected from erosion by <br />planting with the temporary revegetation seed mix. As appropriate, text and maps have <br />been revised to clearly delineate soil stockpile locations and volumes. <br />Item 38. Page 2.05-45.4, line 6. Please add a reference to the description ofthe <br />stabilization seed mixture used to protect topsoil storage piles. <br />Response: The text has been revised to include the requested reference. <br />Item 39. Page 2.05-45.4, line 11. The area of disturbance at the fan shaft is less than the <br />size of the watershed in which it is located. Please revise the SAE discussion to indicate a <br />SAE watershed of 4.3 acres but a disturbance ofX~'Y (number, as demonstrated by the <br />construction drawine ofltem 30) acres. <br />Response: The text has been revised to clarify the relative acreages for watershed and <br />disturbance areas. <br />Item 40. Page 2.05-45.4, line 14. 77te Exhibit 5 referenced was submitted as Exhibit 8T. <br />Please change "Exhibit 5" to read "Exhibit 8T". <br />Response: The text has been revised to read "Exhibit 8T." <br />Item 41. Page 2.05-45.4, line 19. No drainage structures were found on Map 24 as stated. <br />They might be better shown on the plan and profile drawings of the access road (see Item <br />32). Please revise accordinely. <br />Response: The drainage structures aze shown on Map 24, Sheet 3 of 3. <br />Item 42. Page 2.05-45.4. Vicinity of line 27. Criteria for cut slopes was omitted. Please add <br />the generalized design criteria or cut slopes as was done for fill embankments. Typical fill <br />and cut-slope cross-sections, including toe-of--cut-slope ditches, should also be portrayed <br />on the construction design drawings ofltem 32. <br />Response: For both the shaft pad and access road, cut slopes will be established at a <br />maximum of 1.SH:1 V and fill slopes at 2H:1 V. The text and maps have been revised to <br />reflect these design criteria. <br />
