streams at both the upper and lower well field production gathering lines and the <br />injection stream going into the wells. This data represents what would be <br />available to migrate into the overlying aquifers in the event of a cavity breech or <br />mining into a fault or fractured zone. The concentration of the constituents in the <br />solution mining brine shows some key indicators that are markedly greater in <br />concentration when compared to the various concentrations of these same <br />constituents derived from the overlying aquifers. In other words, it is expected <br />that in the event of contact between the brine solution and the overlying aquifers, <br />analysis of these indicator parameters in the ground water system would show <br />evidence and extent of contamination from brine solution as a result of the <br />comparative concentration differences. <br />The data representing each of these constituents is presented in the tables in <br />Appendix A. Following each Table is a series of graphs showing the historical <br />concentration of the constituents in each water bearing zone during both baseline <br />and operational periods. The final graph in each of these series is a compilation <br />of all zones and the production streams. In each compilation graph the markers <br />identifying the production streams are visibly higher in concentration than the <br />aquifer concentrations. It vanes by as much as an order of magnitude to as little <br />as a factor of 2. <br />In order to establish permit condition values that are protective of the <br />environment at points of compliance Numeric Protective Levels and Early <br />Warning Indicators were calculated from baseline data using the Dixion test <br />statistical method unless a regulatory standard is applicable. <br />Reports will be submitted to all three regulatory agencies annually during both <br />the interim status and once commercial production operations resume. The <br />reports will include table summaries of the data and graphical representations for <br />each parameter of all monitoring for the period of record. <br />The following Table 7 -Permit Condition Values or Numeric Protective Levels <br />shows the maximum value for each of the indicator monitoring parameters at the <br />point of compliance. Calculations of baseline data at point of compliance well 21- <br />3D are provided here only for comparison. Numeric protective levels are not <br />established for the dissolution surface. <br />
