PHC: Partial dewatering will occur of the coal unit. <br />This was the case during mining, but the water levels have been steady since 1996. <br />Please note that the data for we1179-61 was either left off the diagram (Fig. 1) in the <br />current AHR or the overlapping symbols make it uncleaz if the triangle representing well <br />79-61 data is present. If the latter is the case, please take Gaze to resubmit that page and <br />clearly show the data for we1179-61. <br />PHC: Temporary drawdown will occur in areas adjacent to the mine. <br />This may have been the case during mining, but since operations ceased, groundwater <br />levels have remained consistent. <br />PHC: There will be a temporary increase in recharge rate after mining. <br />This appears to have occurred but has leveled off in the intervening ten years. <br />PHC: Leaching of soluble ions will occur in backfilled areas. <br />The dissolved solids in the bedrock units have been consistent or have reduced since the <br />late 1990s. Dissolved solids content of well 79-3 is by faz the highest with greater than <br />4000 mg/I TDS. This prediction appears to have occurred to some extent. <br />Dissolved solids in the alluvium of Mann Draw, draining the Pit 1 area, peaked several <br />years ago and TDS of that alluvial water has decreased in the last several years. <br />Water chemistry in the spoils has been consistent over the last four years with TDS <br />values being very similar to water typical of the coal seam from baseline data. T <br />The prediction has proven accurate. <br />PHC: Transport of dissolved salts will occur through bedrock units. <br />This is probably occurring. <br />Additional Comments: <br />1. Please explain the situation with groundwater we1179-3. The diagram shows no <br />historic values, only 2005 values. <br />2. Table 6 appears to be mislabeled. It should read "coal seam water" <br />
