main entries. If available, please provide the Division with an estimate of the quantity of mine inflow <br />water that could potentially be encountered due to development mining across the fault location. <br />Please provide revised text describing BRL's plan for controlling and handling the water, if <br />significant amounts of mine inflow are encountered. <br />Subsidence <br />5. Please update the first sentence in the last paragraph on permit application page 2.05-99 to state that <br />portions of the Terror Creek road are within the permit area, as well as within the adjacent area. <br />6. Please update the discussion in Section 2.4, Buildings and Structures, of Exhibit 15 in Volume III to <br />include the Western Area Power Administration Curecanti-Rifle transmission line and the two <br />transmission line towers. <br />7. On Map 27, the depiction of the D-seam workings is much more prominent than the depiction of the <br />B-seam workings. Please revise the depictions of the B-seam and D-seam workings on Map 27 so that <br />both depictions are more or less equal in prominence. <br />8. On page 36 of Exhibit 15 of Volume III, the first sentence states that ephemeral and intermittent <br />streams are within the permit area. Please add perennial streams to this statement since portions of <br />Hubbard Creek and Terror Creek are within the permit area. <br />9. As required under the subsidence control plan of Rule 2.05.6(6)(f), please add an appropriate <br />discussion concerning the Curecanti-Rifle transmission line and the two transmission line towers to the <br />Subsidence Handbook in Exhibit 15 of Volume III. Also, please add a reference to the transmission <br />line and towers in the next to the last paragraph on permit application page 2.05-116. <br />10. Please update the appropriate maps to show the change in the mine plan. These same maps should be <br />updated with the current permit boundary, if necessary. <br />11. Please provide documentation that surface owners above and adjacent to the underground mining <br />areas proposed in TR-65 have received proper notification of the mining schedule, as required under <br />Rule 4.20.2. <br />Reclamation Cost Estimate <br />12. Attached is the Division's reclamation cost estimate for TR-65 - drilling one geotechnical hole and <br />credit for gob vent holes not drilled. The estimate is comprised of five tasks and represents a decrease <br />in liability of $135,569.00. This decrease is slightly less than the $135,979.00 shown in the estimate <br />submitted by BRL. The main reason for this difference-is that BRL uses a standard percentage for <br />indirect costs versus the actual calculated indirect costs used by the Division. <br />The cost decrease comes from gob vent boreholes not drilled and the associated drill pad and light use <br />road reclamation not needed. The gob vent boreholes that were removed are GVB-9B, GVB-10B, <br />GVB-IODG, GVB-11C, GVB-11D and GVB-11E from TR-52; drill pad 192 from MR-104; and <br />GVB-10B and GVB-10U2 from MR-106. <br />2
