text on Page 12-8 only discusses mining in Section 11 (which <br />should have been completed in 1985). Peabody Coal should revise <br />this section to correlate with what is depicted on Map 1Z-1. <br />RESPONSE <br />The descriptions, Mining Operations-Life-of-I+line and Operations <br />Description-General are revised to clarify mining areas, production, <br />scheduling, and maps. These revised descriptions are based upon <br />current conditions and are reflected on map Exhibit 12-1. The mining <br />plan shown depicts the 7706 dragline completing the Wadge pit and the <br />6506 completing the Wolf Creek pit. <br />As the CMLRB is aware, Peabody plans to revise the current mine plan <br />in the latter part of 1986 to accurately reflect the disposition and <br />placement of both draglines in both the Seneca II and II-W mine areas. <br />Upon finalization of these plans by Peabody and acceptance by the coal <br />supply customer, Peabody will provide the CMLRB an appropriate <br />revision. <br />2.05 Operations Plan <br />2. The Division is concerned that two (2) feet of soil cover is <br />inadequate coverage of the non-coal waste disposal area. It <br />• appears that this sentiment is shared based on a review of Pages <br />12-48a and -48b of the original permit application. Peabody Coal <br />should revise Page 12-50 of the permit application to reflect the <br />twenty (20) foot overburden coverage committed to in the original <br />application. <br />RESPONSE: <br />Page 12-52 is revised in its entirety to reflect a minimum of eight <br />feet of overburden material will be placed over the disposal area. <br />2.05 Operations Plan <br />Point 2 on Page 12-52 discusses topsoil removal from the highwall <br />side prior to drilling and blasting of the overburden. It <br />further states that "The distance or width of this topsoil <br />removal depends largely on how much overburden is needed front <br />this side of the pit". The Division understands Peabody Coals` <br />position; however, the Division is concerned about the potential <br />contamination of topsoil if insufficient material is stripped and <br />overburden material is cast onto non-salvaged areas during a <br />blast. Peabody Coal Co. should commit to a minimum topsoil <br />removal width based on past working experience at the Seneca II <br />Mine. <br />• <br />13 Revised 8/27/86 <br />
