Susan Burgmaier -11 February 7, 2014 <br />BOW2: Please see revised Map 21 -1. <br />39. DRMS: Map 21 -3 Drainage Plans: <br />a) The revised map provides two labels for the ditch entering Pond J from the west. It <br />appears that the label D -116 (in red) is in error and should be removed. Please <br />verify the correct label for this ditch and remove the extraneous label. <br />b) The revised map includes a line, around the J and H drainage areas, that is not <br />identified in the legend. The line is purple, with a "one long and two short" pattern. <br />Please either identify this line in the legend or remove it from the map, <br />BOW2: Please see revised Map 21 -3. <br />40. DRMS: Map 22 -J Pond J Detail: <br />a) Section B -B' of the revised map shows the secondary dewatering pipe being buried <br />in the embankment. Is BRL proposing to abandon this dewatering pipe, or <br />was it inadvertently moved on the drawing? <br />BOW2: The pipe was inadvertently moved. Please see revised Map 22 -1. <br />b) Please provide additional details on the secondary dewatering pipe, <br />indicating the valve location on the drawings and the inlet and outlet <br />elevations under Note #4. <br />BOW2; The inlet elevation is shown in the profile view of Section B -B'. The elevation <br />of the outlet end and the valve is not known at this time and putting it on the map <br />would be an educated guess. After the approval of TR -84, and the expansion of <br />Pond J is complete, the location and elevation can be determined by an as -built <br />survey and will be added to a future version of Map 22 -J. <br />c) Please correct Note t to indicate that the design information for the ponds <br />and ditches (please also add "culverts') is located in Appendix B of <br />Volume XI, <br />d) The details of Section A -A' and B -B' conflict on the full sediment level. A -A' indicates <br />it is 5848'; B -B' is 5850'. Please verify the full sediment level and revise the <br />map appropriately, <br />BOW2; The full sediment elevation should be 5850'. Therefore, the designed water <br />and sediment levels have changed and been revised on Map 22 -3 and on Volume <br />XI, page S. <br />e) On the plan view provided for Pond J, the contour lines are too light to distinguish, <br />so we are unable to view the contour lines to verify the capacity of the pond. <br />
