<br />. <br />COMMENURESPONSE FORM <br />TR-68 <br />1. The sentence on page Exh. 7_14P-3 seems to end in mid-sentence. Please review <br />and correct as necessary. <br />Response: The incomplete sentence has been finished with this submittal. <br />2. In the second paragraph on page Exh. 7-14P-3, Colowyo commits to interim <br />sediment control measures during construction. Please include a description in <br />the text of the measures that will be used (i.e. silt fence, straw bales, etc). <br />Response: A system of internal ditches and/or berms to will be used to direct <br />flows to a siltation fence. This statement has been added. <br />3. In the third paragraph on the same page, please include the size of the rock to be <br />used in the rock filter. <br />Response: Minus two inch rock is now specified. <br />4. Please explain why the 1.1 acres of additional disturbed area would be re-seeded <br />using the access road seed mixture? This area is additional disturbed acres and <br />should likely be re-seeded to the permanent seed mix rather than a temporary mix. <br />Please review and change as necessary. <br />Response: This borrow site will be redisturbed within the next two years when <br />the Section 21 Pond is built. Thus, it would not be appropriate to <br />use a permanent seed mix. <br />5. Please refer to Figure 2, Exh. 7-14P, Borrow Area Sediment Control Plan. The <br />legend inaccurately identifies the rock check dam symbol. Please correct as <br />necessary. <br />Response: The figure has been revised to correct this error. <br />6. It would seem like a bond increase would be appropriate for this additional <br />disturbance, although the application states no increase. <br />Response: As discussed with Jim Stark, no increase in the reclamation bond <br />is needed at this time.
