Site Sl was <br />probed to 60". Sofr sandstone was encountered at 49" decreasing the rate of penetration <br />in this hole. Testing below 48" was not attempted on the other sites. No soil salvage <br />limitations due to rock occurred in any of the sites within the top 48". <br />Soil analysis results are attached. The Potts series showed suitability restrictions due to <br />saline-sodic conditions below 30" in the B-horizon. The top part of this horizon (starting ;~~ <br />at 21 ") was only marginally suitable for use as subsoil on the basis of elevated SAR. <br />H The Satanka series had one interval with marginal suitability due an elevated SAR. This <br />part of the Cca horizon is limited and should not pose a problem when mixed with °~~ <br />adjoining soils during reclamation. <br />Conclusion: <br />~' <br />The Potts series is capable of providing a minimum of 30" and the Satanka series 48" of <br />salvageable cover material for the refuse areas. Additional subsoil would be available <br />from the Potts series with the addition of gypsum to reduce the SAR to acceptable levels. <br />Mine Permit Renewal ~f3 (8/99) ILIA-2 <br />
