stripping that will be required in this undisturbed area. Detailed information regarding the <br />increased area and the volumes of topsoil and subsoil that will need to be salvaged will be <br />required. <br />The Division has no further concerns. In the October 1, 2009 submittal, BRL revised Appendix A <br />of Volume IX to include updates to the topsoil and subsoil salvage and replacement values. <br />11. Based on the increased maximum elevation, starting elevation and area noted in question I above <br />and the increase in capacity of Gob Pile #4 (from 300, 000 cubic yards to 450, 000 cubic yards; <br />Volume IX, Page 4) the surface area of the pile will necessarily increase. This increase in area <br />will require additional subsoil and topsoil to properly cover the pile. Please recalculate the <br />volumes of subsoil and topsoil that will be required to cover the pile with the required depth (three <br />feet of subsoil and one foot of topsoil). <br />The Division has no further concerns. Since there is a topsoil deficiency, BRL intends to change <br />the depth of topsoil replaced from 1.2 feet to 0.9 feet. Therefore, Appendix A of Volume IX was <br />revised accordingly in the October 1, 2009 submittal. The Division approves of this change but <br />encourages BRL to salvage and replace as much topsoil as possible. <br />12. Based on the Division's digitized areas of Gob Piles #1 and #4, which have increased by <br />approximately I acre, the operator's description of the disturbance in the second paragraph on <br />Page 11 of Volume IX will need to be changed. The operator states that the gob piles cover <br />approximately 34 acres and the topsoil piles cover approximately 2.3 acres. The increase in the <br />area of Gob Piles #1 and #4 (of approximately I acre) and any changes to the area of the topsoil <br />stockpile by Gob Pile #4 will need to be accounted for in these totals. These numbers will need to <br />be changed accordingly to account for the changes in the configuration of Gob Pile #4. <br />The Division has no further concerns. BRL changed the acreage numbers on revised page 11 in <br />Volume IX of the submittal dated October 1, 2009. <br />13. Based on the Division's calculation that the area of Gob Piles #1 and #4 increased by <br />approximately I acre, and based on BRL's statement that 363 acres require reclamation (Volume <br />IX, Page I1), the Division believes that there may be a topsoil deficiency for final reclamation of <br />the gob piles and associated areas. BRL states that one foot of topsoil will be placed over three <br />feet of subsoil for final reclamation (Volume IX, Page 11, first paragraph). BRL also states that <br />there is approximately 56,900 cubic yards of topsoil for reclamation. The Division believes that <br />with the increased size of Gob Piles #1 and #4, there are 37.3 acres requiring reclamation. For a <br />flat area the topsoil required to cover these areas to a depth of one foot is 60,200 cubic yards, a <br />deficiency of 3,300 cubic yards (or 0.7 inches). The surface area for the 3:1 and 2.5:1 slopes of <br />the gob piles will be greater than the flat area of 37.3 acres, leading to a greater topsoil <br />deficiency. Please review the topsoil balance for the gob piles and associated areas and revise <br />the topsoil replacement plan as necessary. Note, there does not appear to be a problem with the <br />subsoil for the gob piles and associated areas as there is an excess of almost 40, 000 cubic yards <br />of material.
