Soil testing, as described in Section 2.04.9, Soils Resource Information, indicates that some of the <br />undifferentiated mixed soil and refuse materials in the Pre-Law disturbance areas generally meet <br />revegetation soil suitability criteria, but may have suitability limitations. These areas can effectively be <br />reclaimed through the use of approximately 6 inches of soil material. In addition, surficial and near <br />surface sub-soil and weathered overburden materials may be suitable as a soft substitute or to <br />supplement the available soIl resources. Use of these materials as soil substitutes or supplements has <br />been approved by DMG contingent on testing to verify suitability, as described in Section 2.05.4, <br />Reclamation Plan. Potential suitable material borrow azeas aze shown as excess cut azeas on the <br />Reclamation Cut/Fill Isopach in the Mine Reclamation Material Balance (Exhibit 2.05-ES). The <br />volume of suitable borrow material utilized as soil substitute or supplement will be determined <br />operationally during reclamation based on both material testing and operational requirements. Based <br />strictly on the general objective of assuring that approximately 6 inches of suitable material aze <br />available as a surficial revegetation medium on all disturbed areas, the maximum additional volume of <br />suitable material required for the Elk Creek Coal Handling, Support, and Ancillary Facilities azea is <br />estimated at roughly 19,600 cubic yards. Given that existing surficial materials over much of this area <br />may be suitable, [he actual volumetric requirement may be significantly less. <br />MR-67 3 Revised March 2003 <br />
