It appears that several revisions need to be made to Table 3.1 -1: <br />October 16, 2012 <br />provide revised hydrology designs for those structures using the 100 year - <br />24 hour precipitation event. <br />93. Please provide the Subwatershed Hydrology Detail design sheets and the <br />Structure Summary design sheets for the 100 year -24 hour precipitation <br />event Sedcad run for the operational configuration and the 10 year and 100 <br />year precipitation event Sedcad runs for the reclaimed configuration. <br />MCM: No longer applicable, please see approved SedCad detail sheets in Appendix M. <br />94. What is the reclamation plan for the existing sediment pond before it becomes <br />the topsoil storage area as proposed in PR -2. Please provide a discussion in <br />the permit text that describes the method for reclaiming the current <br />sediment pond, including what will be done with the pond cleanings. <br />95. It appears that page 35 of Appendix M should actually be numbered page <br />31. If this is correct, please revise Appendix M accordingly. <br />96. In the Structure Summary on page 30 and 35 of Appendix M, there are several <br />structures with asterisks. The footnote on page 35 explains that these <br />structures have incomplete design parameters. Please explain. <br />• The side slopes for ditch R11 should be 1.5 instead of 2.0. Please revise <br />accordingly. <br />• The ditch depth for ditch D -R13 -1 should be 1.03 feet instead of 1.3 feet. <br />Please revise accordingly. <br />• The values for the right side slope and the left side slope need to be <br />switched for ditches R17, R18 and R20. Please revise this table. <br />• The side slopes for ditch R22 -b should be 6.0 instead of 2.0. Please revise <br />accordingly. Should be 2.0, revised SedCad. <br />
