SS-15, SS-2 to SS-16, and so on. Locations of the soil samples are <br />• presented in Exhibit 23 in this section and Exhibits 8A, 10A and 11A, lab <br />Section 13. <br />Three (3) areas of possible topsoil salvage were identified and delineated <br />at the Cameo Refuse Disposal Area No.1 (CRDA-1) during a state <br />inspection in 1983. These (3) areas were sampled and analyzed for <br />physical and chemical characteristics. The results of this sampling are <br />listed in Appendix 9-3 and their location is shown on Exhibit 23 and 96. <br />This information was part of a topsoil salvage plan for CRDA-1 which was <br />submitted as Item 9 to the permit in February 1983. Material form these <br />sites was stockpiled in Topsoil Piles 5 and 6 and was used for topsoil <br />cover on CRDA-1 in 1994. <br />Topsoil stripping area boundaries and soil sample locations for CRDA- 2 <br />• and 3 are shown on Exhibits 51 and 52 respectively. Soil sample <br />analyses are found in Appendix 9-4. Soil salvage was completed on <br />CRDA 2 in 1985. Soils of refuse disposal area ~ex~hib o. 2 and 3 <br />exhibit a wide variation in quality. Generally from 1 to 4" of material meets <br />the SAR and EC limits defined in Tab 14 for replacement in the top 6" of <br />cover. As the depth of soil increases the soils become too saline and <br />sodic to support most moderately salt tolerant plant species. The relative <br />crop yield, in percent, drops drastically low when contemplating <br />revegetation with native moderately salt tolerant species on the deep <br />horizon soils. <br />Appendix 9-5 includes Soil Sample Analysis for the South Fan,the 2 West <br />Portal area disturbance, the Cameo Borrow Area's 1 and 2, and the <br />Roadside South Parking Lot. Due to the steep terrain and the high rock <br />• content of the thin topsoil available at the 2 West Portals, separate <br />9-3 (Rev. 7/16/97) <br />
