On revised Map 13 of the submittal dated April 11, 2011, please label pond 1 and pond 2 on <br />the plan view. . <br />CAM - Please see revised Map -13. <br />Division Response: In the submittal dated July 8, 2011, all of the ponds were properly <br />Iabeled. However, the revised plan now involves three sediment ponds and a revised <br />Map 13 will need to be submitted. <br />48. In the April 11, 2011 submittal, CAM elected to remove the four silt fence designs for haul <br />road no. 1 from Exhibit 9, leaving a bean with silt fence in places. However, the Division <br />requests that the ditch representation on Map 16 that runs along haul road no. 1 be <br />removed, leaving only the berm representation and the silt fence representation. <br />CAM - Please see revised Map -16 <br />Division Response: In the July 8, 2011 submittal, CAM also removed the silt fence <br />designation and replaced it with an excelsior log designation. However, please remove the <br />silt fence notation and arrows that appear on Map 16 for that section of haul road no. <br />1 and revise the permit text on permit page 2.05.22 to describe the new sediment <br />control situation. <br />49. Item resolved. <br />49a. As required under Rule 4.03.1(4)(e), please provide designs which show that the bridge <br />can safely pass the runoff from a 100 year -24 hour precipitation event. <br />CAM - See new Exhibit 18. <br />Division Response: CAM provided a new Exhibit 18 which shows that the water in Reed <br />Wash can safely pass underneath the proposed bridge. However, the Division requests <br />that CAM provide a more detailed description of the results in the report, especially <br />what the different profiles on the cross sections represent. In addition, please <br />provide the name of the preparer on page 2 of the report and change from seven <br />channel piers to five channel piers in the third line from the top of the same page. <br />Finally, please reference the Exhibit 18 report on permit text page 2.05 -9. <br />50. As explained in the April 11, 2011 revised permit text sections 2.05.3(4), 2.05.6(2) and <br />2.05.6(3), Exhibit 9 and Map 16, berms and silt fence will be used to contain any coal spills <br />that might occur near Reed Wash. However, examination of Map 16 shows that there is a <br />section of Reed Wash that is about 350 feet northwest of pond 2 that comes to within 60 <br />
