Corey Heaps <br />CAM Colorado LLC <br />June 21, 2011 Page 39 <br />Division Response: Response accepted. <br />60. If CAM elects to revise the sediment control system and eliminate any of the sediment <br />ponds for the railroad loop and, instead, uses best management practices, please revise <br />the protection of hydrological balance discussion in Section 2.05.6(3), the water depletion <br />estimate in Section 2.04.11(4) and any other relevant permit section. <br />CAM Response: Please see revised sections 2.05.6(3) and 2.04.11(4). <br />Division Response: Response accepted. <br />60a. Language addressing the requirements of 2.05.3(4)(a)(ii)(B) is provided on page <br />2.05 -18. This section, regarding embankment construction, may not be required, <br />since Ponds 1 and 2 are both incised. Please remove or revise, if appropriate. <br />Rule 2.05.3(5) Topsoil Removal and Replacement <br />61. Narrative regarding haul road and access road design/construction and reclamation in <br />Section 2.05.3(3) indicates that topsoil (if available) would be salvaged from haul roads <br />and that both haul roads and the access road would be topsoiled during final reclamation. <br />This conflicts with information in soils baseline and removal /replacement sections of the <br />application indicating that the roads are located within previously disturbed areas where no <br />topsoil is available. Map 9 ( "Topsoil Distribution Plan") does not depict topsoil <br />replacement on the reclaimed haul road or access road corridor disturbance areas. Please <br />revise the application as warranted for clarity and consistency. <br />CAM Response: Text on page 2.05 -10 has been revised to reflect the fact that no topsoil is <br />available for salvage. Text regarding topsoil replacement during reclamation has been <br />removed from pages 2.05 -12 and 2.05 -14. <br />Division Response: Response accepted. <br />62. Given the high salinity /sodicity of the topsoil to be salvaged and stockpiled, it is <br />recommended that salt tolerant shrubs including fourwing saltbush and greasewood be <br />included in the stabilization seed mix for use on the topsoil stockpile. Please revise the <br />seedmix to include salt tolerant shrub species. <br />CAM Response: The temporary seedmix, as shown in Exhibit 4, Table SM -1 has been <br />revised to include fourwing saltbrush and greasewood. <br />Division Response: Response accepted. <br />63. Please provide detail regarding topsoil stockpile construction and revegetation; specify <br />stockpile outslopes no greater than 3:1 to facilitate establishment of seeded vegetation and <br />
