Lochhead <br />Eaecuhve Director <br />Michael B. Long <br />Division Director <br />Today I spoke with Christine Johnston and Paige Seville of Mountain <br />Coal Company (MCC). The phone call occurred at approximately 4:05 <br />p.m. <br />Christine stated that the inflows are still occurring at an <br />approximate rate of 7600 gallons per minute (gpm). Christine <br />stated that the water inflow exhibits a temperature of about 83 <br />degrees F. I asked how MCC is measuring the inflow, and Christine <br />stated that crews are estimating flow velocity and flow cross <br />sectional area in the entries. Christine stated that MCC is <br />pumping about 1100 gpm to the surface Pond MB1, and that about 850 <br />gpm are being transferred to underground sumps in sections 1 <br />through 7. Christine stated that MCC was not yet discharging to <br />the North Fork of the Gunnison River. She stated that water had <br />filled Cell 1 of Pond MBl, and that water was being transferred to <br />Cell 2 of Pond MB1. Christine indicated that Pond MB2R also has <br />available, and as yet, unused storage volume. Christine indicated <br />that the site ponds would be filled to the level which would still <br />allow the designed storm volume to enter the ponds, then discharge <br />would occur. <br />Christine also indicated that the MCC water sampling consultant <br />would be conducting hydrologic sampling and observations in <br />Sylvester Gulch to monitor stream flow, well levels and springs. <br />She indicated that wells SOM-80, RAV-4b and one other well, perhaps <br />in the Barren Member would be checked. <br />Both Paige and Christine seemed to think that once discharge <br />occurs, the water would probably exhibit suspended solids above <br />
