• cone of depression in the middle of the well field (as a result of <br />water well) can be noted. This data indicates that direction of <br />ground water flow during 1990 pumpage in the A and B-Groove <br />aquifers was toward the water well. water well pumpage is <br />expected to continue to draw water from all directions within the <br />A and B-Groove aquifers. Therefore, potential water quality <br />impacts on the A and B-Groove aquifers would be contained or <br />consumed on the mine site during pumpage. <br />3.0 Proposed Operations for 1991 <br />Solution mining operations will begin simultaneously with the <br />process plant startup. Both are expected to begin in the first <br />• quarter of 1991. <br />3.1 Drilling/Recompletion <br />In addition to the startup of the plant and initial solution <br />mining, the following wells are expected to be drilled. <br />1. Two dual well/horizontal well pairs with approximately 1,000 <br />foot mining cavities. <br />2. Any water monitoring or subsidence wells as may be required. <br />Refer to Figure 2-4 for proposed wells and cavities and associated <br />product/water lines. <br />Na26-IRI-5 will be plugged and abandoned or converted to a Perched <br />• aquifer monitoring well. <br />51 <br />
