Corey Heaps <br />CAM Colorado LLC <br />June 21, 2011 Page 49 <br />compliance with the various requirements listed under 4.18(5), and reference application <br />sections or maps where relevant details are provided. Specifically address the potential that <br />sediment ponds could present a wildlife hazard due to the industrial wastes present on site, <br />and identify protective measures that would be employed if warranted. <br />CAM Response: Text regarding raptor protection and stream buffer zones has been <br />included on page 2.05 -44. There will not be any special protective measures employed to <br />deal with the sediment ponds due to the perceived risks associated with industrial wastes on <br />site. This area received Closure Certification from CDPHE on August 25, 2005 for <br />residential /unrestricted use (Exhibit 15). If the CDPHE has approved the area for <br />residential use, the operator believes wildlife will be safe from any perceived risk due to <br />the industrial waste located on site. <br />Division Response: Please include in the narrative a discussion about items (a -k) listed in <br />Rule 4.1 and what mitigation measures (if any) were taken to address each bulleted <br />item. Specifically address the potential that sediment ponds could present a wildlife hazard <br />due to the industrial wastes present on site. Include in the discussion: if water will be <br />stored in the sediment ponds for extended periods of time, the potential toxicity level of <br />standing water in the ponds (if any), water quality monitoring and identify wildlife <br />protective measures that would be employed if warranted. Also, please submit <br />construction designs of powerlines that incorporate principles to reduce avian <br />electrocution.

In Subsection (2)(a)(iii) please specifically describe and provide design details for silt fence <br />or measures to be maintained along the toe of the rail spur fill that comes into contact with <br />the irrigated wetlands west of Reed Wash. can design after rail spur design is complete <br />CAM Response: Please see revised page 2.05 -45 to 46 and new silt fence designs, SF -1 <br />through SF -8, shown in Exhibit 9 on pages Exh. 9 -35 through 50. <br />Division Response: Response accepted. <br />Rule 2.05.6(33) Protection of Hydrological Balance <br />89. In the Probable Hydrologic Consequences (PHC) discussion of Subsection (b)(iii) there is <br />no discussion of the potential for leachate entering into the shallow alluvial groundwater <br />from the sediment ponds. As discussed earlier in this letter there is a very good possibility <br />that leachate from the ponds would discharge directly to groundwater since pond bottom <br />elevations are very close to the groundwater table. Please add an additional analysis here <br />that accounts for the leachate from the sediment ponds that may enter into the <br />groundwater, and potentially into Reed Wash. It may be appropriate to combine the <br />
