• 33,800 Cy of material from CBA 1 and 15,000 Cy of material from CBA 2. The <br />location of these areas and the proposed extent of excavation are shown on <br />Exhibits 9A and 52. Topsoil and associated vegetation was salvaged from these <br />areas to a depth of 6" and redistributed or stockpiled in temporary piles within the <br />disturbance areas. All available borrow material was used from CBA 1 and the <br />area reseeded in 1994. Salvage of the material will continue at CBA 2 with <br />similar topsoil salvage, storage and redistribution. Soil sample analysis can be <br />found in Appendix 9-5. <br />Information relating to topsoil salvage at Cameo Refuse Disposal Areas Nos. 2 <br />and 3 (CRDA 2 and 3) was approved as Permit Revision 01 (PR-01) in 1985. <br />The following discussion briefly summarizes the results of sampling included in <br />PR-01 and the location of additional information relating to these areas. Soil <br />sample analyses can be found in Appendix 9-4. Soil removal boundaries and <br />soil sampling locations are shown on Exhibits 51 and 52. Soils at both CRDA 2 <br />• and 3 show good to poor quality as presented in Tables 1 - 3, Appendix 9-4. <br />Deep horizon soil analyses are presented in Tables 4 - 6, and Upland Area <br />analyses are presented in Tables 7 & 8, Appendix 9-4. <br />Topsoil was to be removed to a depth of six (6) feet within the limits of <br />disturbance at CRDA #2. It was estimated that the topsoil removed from the 4.6 <br />acres would result in approximately 44,000 cubic yards (Cy) of salvaged <br />material. Based upon on-site evaluations at the time of removal, poor soil <br />quality, primarily high SAR, resulted in the salvage of approximately 16,000 cy of <br />suitable material. <br />The depth of salvageable material at CRDA 3 is highly variable. No material will <br />be salvaged from CRDA-3 at this time since the Operator does not plan to <br />construct CRDA-3 at this time because the mine is idle and is not expected to <br />operate in the foreseeable future. Several areas have soils removed to a depth <br />of 10 feet, while other locations can only be removed to a depth of one foot or <br />• less to avoid encountering the shale and other high SAR and EC soils. <br />13-18 (Rev. 1 /00) <br />
