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. The soil profile analyzed was based on a conglomeration of soil <br />information from exploration locations ET02-BHO6, ET02-TP03, ET02-13HO5, No. 1, No.2 and MW-3. <br />The model analyzed; a soil overburden that was 9 feet thick, a sand and gravel layer that was 21 feet <br />thick, and a total pit depth of 30 feet. The highest groundwater monitored in the area was in MW-3 <br />approximately 10 feet below the ground surface. <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 />Phase I B <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 a conglomeration of soil information from exploration locations <br />ET02-BHO1, ET02-TP05, No.9, No.10 and MW-1. The model analyzed; a soil overburden that was 9 <br />feet thick, a sand and gravel layer that was 19 feet thick, and a total pit depth of 28 feet. The highest <br />groundwater monitored in the area was in MW-1 approximately 10 feet below the ground surface. <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 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 a conglomeration of soil information from exploration locations <br />PA04-BHO7, No.5 and MW-13. The model analyzed; a soil overburden that was 6 feet thick, a sand and <br />gravel layer that was 14 feet thick, and a total pit depth of 20 feet. The highest groundwater monitored <br />in the area was in MW-1 approximately 9 feet below the ground surface. <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 />Parsons Mine <br />DRMS 112 Permit <br />Page SE3 of SE8
