22. On proposed Figure 3, "Coal Mine Waste Disposal Area - Pond F Detail ", please revise the <br />ditch depth and flow depth values for ditches UpDivWestl, UpDivWest2 and UpDivEast to <br />conform to the values obtained in the ditch designs. The ditch depths should be 1. 51 1.4 and 1.6 <br />respectively and the flow depths should be 0. 5, 0.4 and 0.6 respectively. <br />The Division has no further concerns. The ditch information was updated on Figure 3 in the <br />October 1, 2009 submittal. <br />23. On proposed Figure 3, "Coal Mine Waste Disposal Area - Pond F Detail " in Volume IX, please <br />revise the as-built pond F water volume, sediment volume and total pond volume values to <br />conform to the designed values shown on revised page App. B-4. The revised water volume, <br />sediment volume and total pond volume values are 3.66, 0.18 and 3.84 acre-feet respectively. <br />The Division has no further concerns. In the submittal dated October 1, 2009, the Pond F <br />information on Figure 3 was revised. <br />24. The design parameters for the required water volume, sediment volume and total volume have <br />changed for pond D as well. Volume IV and Drawing No. 95266-04 in Volume IV contain the <br />pond D design parameters but this information was done by Westec. Since the revised required <br />pond capacities are less than and close to the previous values, it does not appear to be worth the <br />effort to ask Westec to revise Volume IV or their pond D drawing. However, in order to avoid any <br />confusion, please add to page 2.05-29 of Volume I a reference to the pond D design information <br />located in Exhibit 8 of Volume III. <br />The Division has no further concerns. Page 2.05-29 was revised in the October 1, 2009 submittal <br />to include a reference to the pond D information in Exhibit 8 of Volume III. <br />25. Please replace the silt fence/straw bale designation at the material storage area shown in the plan <br />view drawing on Map 22-C in Volume IT Also, please add in the legend to Map 22-C what the <br />designations are for the silt fence/straw bales and the berm at the material storage area. <br />The Division has no further concerns. Map 22-C was revised in the October 1, 2009 submittal to <br />include the silt fence designation. <br />General Review <br />26. Please update the Probable Hydrologic Consequences section of Volume I to account for the <br />increase in storage capacity of gob pile no. 4 from 300, 000 cubic yards to 450, 000 cubic yards. <br />The Division has no further concerns. The Probable Hydrologic Consequences section was <br />updated on pages 2.05-74 through 76 in BRL's October 1, 2009 submittal. <br />27. Please update the operations description of the gob piles on permit application page 2.05-8 in <br />Volume I to include the status, including that of TR-64, for all of the operational gob piles. <br />The Division has no further concerns. In the October 1, 2009 submittal, pages 2.05-8 and 9 were <br />revised to include additional information on the gob piles. <br />6
