' 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 1998). Water quality data for 32-7M was collected in 2001 prior to mining it <br />' out and is included in Appendix C of the Seventeenth Annual Hydrology Report (January <br />2002). Comparing the 2001 data to the 1997 data indicated only slight changes with a <br />general improvement in quality for most parameters of 32-7M. <br />2.2.1.5 Mine Water Balance Table 2-2 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 19961997 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 />
