As requested by BRL, this reclamation cost estimate also includes a credit for gob vent borehole GVB- <br />6F, which was not drilled. This credit amounted to approximately $12,000. The credit is based on the <br />estimated cost from Minor Revision No. 78. <br />Please inform the Division in writing whether or not this cost estimate is acceptable to BRL. <br />Section 4.05.3. Diversions and Conveyance of Overland Flow <br />On proposed Map 36b of TR-52, the pad contours are parallel to the topographic contours so no such <br />collection ditch would be needed for the cut slope disturbance. However, a contingency plan should <br />be in place in the event that a collection ditch would be required. Please revise Map 36b to reference <br />a designed collection ditch as a contingency plan. <br />The Division has no further concerns. The March 3, 2008 submittal contained an updated Map <br />36b which contained a collection ditch designation, if one should be needed in the field. Permit <br />application page Exh-8-29i was also revised to include this ditch design. <br />4. A note appears on proposed Map 36b that describes the construction ofa berm around the drill pad <br />topsoil stockpile. However, no berm appears in the drawing, as was done on approved Map 36a. <br />Please include a berm around the topsoil stockpile in the drawing on proposed Map 36b. <br />The Division has no further concerns. A revised Map 36b was provided in the March 3, 2008 <br />submittal that shows the berm designation around the topsoil stockpile. <br />Public and Other Agency Comments <br />Attached is a comment letter that the Division received from the Colorado Division of Water <br />Resources concerning TR-52. That agency has no concerns with the proposed activities. If'and when <br />any additional comment letters are received, they will be forwarded to BRL. <br />No response was necessary. <br />If you have any questions, please call me. <br />Sincerely, <br />Hosephudash <br />Environmental Protection Specialist <br />Attachment <br />cc: Jim Stover P.E.
