Mike Boulay -31- April 11, 2011 <br />CAM : Please see revised text on page 2.05-19 and 2.05-54 & 55. Dewatering <br />will be accomplished by use of a 2" trash pump. The discharge hose will be <br />placed directly in the waters of Reed Wash in order to protect Reed Wash from <br />erosion. Excessive siltation disposal should not occur due to discharge of water <br />from the sediment ponds. As stated in section 2.05.6(3)(b)(iii), sediment ponds <br />will improve the quality of the surface water flowing through and out of the <br />proposed permit area and adjacent area because sediment loads will be <br />reduced. This will reduce the total suspended solids in the surface water regime. <br />58. On permit text pages 2.05-18 and 2.05-19 in Section 2.05.3(4)(a)(ii)(C), please <br />describe where the excess sediment from the pond cleanings will be disposed. <br />CAM : Pond and ditch cleanings will be hauled back to the McClane Canyon <br />mine and either placed in the sediment drying location, or the approved Coal <br />Mine Waste Disposal area. Please see revised page 2.05-27. In addition, <br />pages 2.05-16 through 2.05-20 have been revised to reflect the revised <br />sediment control plan. The McClane Canyon mine will need to incorporate this <br />activity into their permit. <br />59. As stated on permit text page 2.05-20 in Section 2.05.3(4)(d), the Division has to <br />make a finding that runoff from disturbances within 100 feet of Reed Wash will <br />comply with Rule 4.05.18. If sediment ponds 3 and 4 are eliminated and best <br />management practices are employed through a revision of the sediment control <br />system for the rail loop, please revise permit text page 2.05-20 to show how <br />the requirements of Rule 4.05.18 will be met. If silt fence is used, the Division <br />requests that Sedcad designs for silt fence be provided for those stream buffer <br />zone areas in order to demonstrate compliance with the stream buffer zone rule. <br />The Division will make the findings once the sediment control system designs <br />have become final. <br />CAM: Please see revised page 2.05-20, and Exhibit 9 pages Exh. 9-35 <br />through 50. <br />60. If CAM elects to revise the sediment control system and eliminate any of the <br />sediment ponds for the railroad loop and, instead, uses best management <br />practices, please revise the protection of hydrological balance discussion in <br />Section 2.05.6(3), the water depletion estimate in Section 2.04.11(4) and any <br />other relevant permit section. <br />CAM: Please see revised sections 2.05.6(3) and 2.04.11(4). <br />Rule 2.05.3(5) Topsoil Removal and Replacement <br />61. Narrative regarding haul road and access road design/construction and <br />reclamation in Section 2.05.3(3) indicates that topsoil (if available) would be
