This concern has not been addressed. Please provide the predictions, based on paztial year <br />monitoring, as requested. <br />DMG Item 2a: <br />The table on page 4.6-143 omits electrical conductivity from the listed parameters and lists only <br />specific conductance. Because P&M has stated that specific conductance values are corrected <br />for temperature, the Division assumes that all reported values have been temperature- <br />corrected. P&M should verify this. <br />DMG Item 26: <br />This concern was addressed adequately in Appendix 2.5-A but was not addressed at all in <br />Section 4.6. Please include the information in Section 4.6. <br />DMG Item 2c: <br />P&M has not provided an explanation for TDS values exceeding conductivity values. Although <br />Tables 1 and 2 indicate how TDS values were derived, the use of the equation in Table 2 is <br />invalid for two reasons: 1) it results in TDS values which exceed the conductivity value, and 2) <br />the temperature dependence of electrical conductivity is not taken into consideration. In <br />addition, the requested discussion of the history of using equations for deriving TDS levels from <br />conductivity readings was not included. <br />DMG Item 3a• <br />This concern was addressed adequately in P&M's first response. <br />DMG Item 3b: <br />This concern was addressed adequately. <br />DMG Item 4: <br />This concern was addressed adequately. <br />DMG Item 5: <br />This concern has not been addressed. Please include 1992 data in its entirety on pages 2.SA-8, <br />-13, and -14. <br />DMG Item 6: <br />Section 2.5-B-1 states that sulfate concentrations at NPDES outfall #006 are approximately <br />ever ontare 3 cto er 1 , 1 3 <br />
