RESPONSE: Page 2 in Exhibit D has been revised to indicate the maximum length of the highwall <br />measured from the center of each 3:1 side slopes on the north and south limits of the excavation <br />limits. The side slopes will be mined at: 3H:1 V. A typical cross section depicting the configuration <br />of the high wall mine face has been added to Sheet 3, Exhibit C. <br />5) Once mining moves from Phase I into Phase II, what portion of Phase I and Phase II will <br />be disturbed? Also, please speck the maximum proposed disturbance in acres. This <br />information is required to accurately calculate a reclamation cost estimate. <br />The response submitted states that 10 acres is the proposed maximum disturbance. Will the <br />existing 9.9 acres of disturbance be completely reclaimed and revegetated prior to moving into <br />Phase II? <br />RESPONSE: The maximum disturbance will be 19.9 acres. This includes Phase I and Phase H. It <br />should be pointed out that reclamation activity in part of Phase I will occur at the same time as the <br />mining efforts in Phase II. <br />In addition to the Huddleston-Berry response to Mr. Allen Sorenson's Geotechnical Exhibit Review <br />the following revisions have been made: <br />1. The overburden stockpiles along the south boundary of the mining area have been <br />eliminated on Sheet 2, Exhibit C. <br />2. References to the underlying "stony clay loam" stratum have been eliminated in Exhibits C, <br />D and F. <br />If you have any questions or require any additional information do not hesitate to contact me. <br />Respectfully, <br />Tom g ge <br />xc: Leon Moores
