fracturing of the Wolf Creek due to mining is improbable. Inflow from the Wolf Creek coal seam into the open or reclaimed pits is not expected to occur. The Wadge coal and its overburden, which may locally contain the Lennox coal seam, generally stores and transmits water. While mining, water will be induced to flow into active and reclaimed pits. This water will flow mainly from the Wadge coal, but also from the overburden. The operator estimated the following values for aquifer characteristics in the Wadge Coal and Wadge Overburden: ' Hydraulic conductivity of overburden = .Ol ft./day ' Hydraulic conductivity of coal = 0.02 ft./day (north pit), .Ol ft. day (south pit) ' Storativity = 10"Z for both aquifers ' Transmissivity = 4.5 ft. Z/day for overburden ' Transmissivity = 0.12 ft. 2/day for coal ' Hydraulic gradient of overburden = .165 (north pit), .085 (south pit) ' Hydraulic gradient of coal = .15 (north pit), .11 (south pit) The preceding estimated values for hydraulic conductivity and transmissivity are somewhat lower than most values reported for these aquifers by mines in the area. Tables 5 and 6 in Robson and Stewart's (1990) report indicates ranges in hydraulic conductivity from 0.1 to 0.6 ft./day for the overburden aquifer and two values of .02 and .4 ft./day for the Wadge Coal. The Division's PHC findings are based on the possibility of greater inflows than those predicted by the applicant. The Williams Fork Formation overburden which locally contains the Lennox Coal Seam, may contain perched aquifers as well as acting as a limited aquifer system near the Wadge coal. The overburden does not contain or transport significant amounts of water in this area. The applicant states that no hydrologic effects due to mining will be noticed at Temple Well No. 1 (a domestic water right), a little south and west of the mine site. Eventually, some effects will be seen at this well. The effects may be exhibited as increased levels of dissolved solids or other chemical parameters (sulphur, iron) and/or diminished quantity of water at the well. These effects will probably not be seen until a number of years after mining has reached its closest point to the well. Eventually, effects will diminish as the dissolved solids are leached from the spoils, and the aquifer characteristics return to normal. Locally, the major impacts of mining include affecting the quantity and/or quality of Springs S-1, S-5, 5-23, 5-41 and S-45. Effects of mining at these sites will not be observed for a few years after mining is at its closest to these points. 27
