<br />' 2.2.1.4 Bedrock Water Quality Water sampling and analysis are no longer required from <br />the bedrock monitoring holes. However, as required by DMG, prior to entering Federal leases <br />C-8424 and C-8425, one water quality sample was collected and analyzed from each of the <br />monitoring holes in federal leases C-8424 and C-8425. Such sampling was limited to the <br />' middle (coal facie) zone. <br />The Deserado Mine First Annual Hydrology Report (December 1985) contains baseline water <br />' quality data for the bedrock zones except for wells in federal leases C-8424 and C-8425. <br />Baseline water quality data for these wells are given in the Thirteenth Annual Hydrology <br />' Report (January 1999). <br />2.2.1.5 Mine Water Balance Table 2-3 shows the water balance for the Deserado Mine. No <br />' water has been pumped from underground workings since January 10, 1996. Electric power <br />to the pumps has been cut off due to the underground fire; the pumps have been removed. <br />' During the 1996-1997 period, Deserado Mine started disposing the prep plant thickener water <br />in the mined out area of the D-Seam (the first longwall district). This water would have been <br />otherwise discharged through Pond PP-2. A description of how these numbers are arrived at <br />follows. <br />1 <br />1 <br />1 <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br />TABLE 2-3 <br />MINE WATER BALANCE <br />WATER IN GALLONS/YR GALLONS/MIN <br />Production Equipment 36,132,000 68.74 <br />Ventilation Humidity 9,574,300 18.22 <br />Underground Storage of Thickener Water 10,722,000 20.40 <br />Incidental (pipe leaks, road) watering, wash down 4,056,150 7.72 <br />TOTAL 60,484,450 115.08 <br />WATER OUT <br />Coal Surface Moisture 6,736,153 12.82 <br />Ventilation Humidity 19,968,000 37.99 <br />Pumped Out 0 0 <br />TOTAL 26,704,153 50.81 <br />Water Left Underground 33,780,297 64.27 <br />9 <br />
