<br />7.Page 2.05-41 states that “Markers will be installed in Pond F clearly indicating the required <br />sediment cleanout level and maximum water level that could occur while still allowing ample <br />storage for the design event.” BRL will need to verify that the markers reflect the sediment <br />and water levels approved with this revision. A response from BRL is not required. <br /> <br />The diversion ditches around the refuse expansion area will need to be completely <br />constructed and lined (rip rap) prior to placement of any refuse beyond the currently <br />constructed diversion ditches. Care should be taken to ensure that rip rap selection and <br />placement in the ditches is consistent with the notes on Figure 3 (Pond F Detail); specifically, <br />the rip rap needs to be well graded to ensure that voids are filled. A response from BRL is <br />not required. <br /> <br />Rule 4.05.6(4) and 4.05.9(2) <br /> <br /> <br />Item Resolved. <br />8. <br /> <br /> <br />Item Resolved. <br />9. <br /> <br />Rule 4.05.3(7)(b) <br /> <br /> <br />Item Resolved. <br />10. <br /> <br />Rule 4.10.4(2) <br /> <br /> <br />Division Response: <br />11. BRL responds that a cut slope of 1.5H:1V should be considered stable, <br />just as it would be allowed for a road cut. The difference in this case is that should a failure <br />occur, cleaning of this ditch will be much more difficult than cleaning of a roadside ditch <br />would be. The proposed slope will be acceptable, under the condition that BRL conducts <br />inspection (and cleaning, if necessary) of the ditch on a regular basis. It is critical that flow <br />never be diverted onto the surface of the Gob Pile. A response from BRL is not required. <br /> <br />The Division calculated a reclamation cost estimate for the expansion of gob pile #2 as proposed in <br />TR-72. The increase in liability for TR-72 is $18,135.11. The mine’s current liability is <br />$9,069,867.82 and bond held is $9,155,156.00 (the difference is $85,288.18). Please review the <br />attached cost estimate and inform the Division if the estimate is acceptable. <br /> <br />If you have any questions, please contact me. <br /> <br />Sincerely, <br /> <br />Brock F.
