Individual Cross Sections <br />Phase IA <br />The bedrock in this phase dips slightly northward. Therefore a worst case scenario is represented by the <br />north mining highwall of this phase. Three soil profiles were analyzed based on soil information from <br />exploration locations ET02-131-105, No. 1, and MW-3. <br />A soil screening berm was placed north of the pit. Flood irrigation, north of WCR 641/2, was simulated <br />by raising the piezometric surface, under the road and in the borrow ditch just south of the existing road, <br />above the highest monitored surface to the ground surface. <br />The road is planned to be widened. The widening will result in the ditch being relocated southward. <br />The controlling case is ET02-131-105 with a setback distance of 47 feet. <br />Phase 1B <br />The deepest depth to bedrock near a structure occurs near the northwest portion of the mining cell. <br />Three soil profiles were analyzed based on soil information from exploration locations No.3, ET02- <br />BHO1, and No. 10. <br />An overburden stockpile was placed northwest of the pit. No flood irrigation is near this mining cell; <br />therefore the piezometric surface was based on the site monitoring. The controlling case is No.3 with a <br />setback distance of 39 feet. <br />Phase IC <br />The deepest depth to bedrock near a structure occurs near the northwest portion of the mining cell. The <br />soil profile analyzed was based on soil information from exploration location No.5. <br />An overburden stockpile was placed northwest of the pit. No flood irrigation is near this mining cell; <br />therefore the piezometric surface was based on the site monitoring. <br />Phase 2 Eastside <br />The depth to bedrock in this area is greatest in the middle of the mining cell. Therefore a worst case <br />scenario is represented by the middle of the east mining highwall of this phase. The soil profiles <br />analyzed were based on soil information from exploration locations No.3, and MW-4. <br />An overburden stockpile was placed east of the pit. No flood irrigation is near this mining cell; <br />therefore the piezometric surface was based on the site monitoring. The controlling case is No.3 with a <br />setback distance of 39 feet. <br />Parsons Mine <br />DRMS 112 Permit <br />Page SE3 of SE7
