required for reclamation and a task accounting for the additional 5.63 acres of revegetation that <br />is required. Please review the attached cost estimate and inform the Division in writing whether <br />or not the estimate is acceptable to BRL. <br />Surface Water Hydrology Review <br />17. In the table labeled "Appendix B " on proposed page App-B9, there are several entries for peak <br />flows that do not correspond to those listed in the current or proposed designs. These peakflow <br />entries are for ditches Fl, F2, F9, Flt, F13, F14, F16, F17, F18, East Diversion, West Diversion <br />#1 and culvert F2. Except for ditch F2, it appears that the designs for these ditches and one <br />culvert were revised but not included in TR-64. Please provide the revised designs or revise <br />proposed Appendix B accordingly. <br />The Division has no further concerns. In the submittal dated October 1, 2009, BRL provided <br />designs for the referenced ditches and one culvert in revised pages App-B 12, 20, 22, 24, 25, 27, <br />28, 29, 31, 32, 32i, 33 and 33i. <br />18. Comparison of currently approved Map 15-3, Map 21-3, Figure 1 and Figure 2 with the <br />comparable maps and figures that are proposed in TR-64 shows that the designation of the <br />western flowing extension of West Diversion Ditch #1 has been eliminated. Previous field <br />inspections have indicated that the West Diversion Ditch #1 had an eastern flowing component <br />and a western flowing component and that the western flowing component diverted undisturbed <br />runoff to the west, away from the western extent of the gob pile. Unless this situation has changed <br />in the field, please add this ditch designation back onto these two maps and these two figures. <br />The Division has no further concerns. Maps 15-3, 20 and 21 and Figure 1 and 2 were revised in <br />the October 1, 2009 submittal to show the ditch segment. <br />19. The TR-64 submittal includes a proposed page Exh 8-20. However, the Division's copy of the <br />permit application for Exhibit 8 already has page Exh 8-20. It appears that this proposed page <br />should be Exh 8-19i. Please revise this page number accordingly. <br />The Division has no further concerns. The page numbering of Page Exh 8-20 was changed to page <br />Exh 8-19i in the October 1, 2009 submittal. <br />20. In the table "V-Ditch Design " on proposed page Exh 8-29i, the peak flows for ditches D5, D6, D7 <br />and D8 do not correspond with the peak flows given in the new ditch designs. Please revise <br />accordingly. <br />The Division has no further concerns. In the October 1, 2009 submittal, page Exh 8-29i was <br />revised to include the updated ditch design information. <br />21. In the table "V-Ditch Design " on proposed page Exh 8-29i, the design entries for ditch GVB7 <br />have been removed. However, this ditch still appears on Map 36B. Please add the GVB7 <br />information to the table or explain why the information was removed. <br />The Division has no further concerns. Page Exh 8-29i was revised in the October 1, 2009 <br />submittal to include the ditch information. <br />5
