It is not anticipated that Bowie would remove <br />the top 6" of native material before placement of topsoil, therefore Appendix A has <br />been revised accordingly. <br />DRMS 4130114: Revised Appendix A addressed this concern; this item is now resolved. <br />ii. DRMS: BRL, in Appendix A of Volume IX, has provided an updated estimate of the <br />volume of stockpiled topsoil. The revised estimate is considerably lower than the <br />previous estimate (42,472 cy as opposed to 72,521 cy approved with TR -76). Please <br />explain why the available topsoil volume estimate has decreased, and demonstrate <br />that this change is consistent with the requirements of Rules 4.06.2(a), 4.06.2(b), <br />and 4.06.4(2)(a). <br />BRL: The volume approved with TR -76 was based on a SurvCad calculated volume <br />(50,326 CY) and included estimated volumes from the borrow area, and the TR -72 & <br />TR -76 areas. The most recent volume calculated is believed to be accurate and what <br />is actually in each stockpile, not what might be available in the TR -76 expansion area. <br />If topsoil is available, it will be salvaged, but for reclamation estimates, it was left out <br />to be conservative in our calculations. <br />As discussed in Section 2.05.3(5) the amount of topsoil that is estimated for salvage <br />can be less than the amount of topsoil actually salvaged. The reasons listed in the <br />permit which apply for the gob pile area are: <br />1. Rocky soil material made topsoil salvage very difficult. <br />2. The steep terrain made topsoil salvage very difficult. <br />3. The soil survey assumed a constant topsoil salvage depth over the entire gob <br />pile area. The topsoil depth varies, from a few inches to over a foot. <br />The Operator believes they salvaged all topsoil that was available for salvage. <br />Page 2.05 -66 acknowledges a 6" replacement depth of topsoil on the gob piles is <br />marginal, however, nutrients or other soil amendment will be applied to redistributed <br />topsoil if necessary to support plant nutrient requirements. Therefore, the Operator <br />
