The hydrographs of the "lower sandstone facies" are designated by the letter "L" following <br />the hole number. <br />Hole 2 -17L showed a rise of 17.7 feet from the prior year. This rise is attributed to the rise <br />in water level within the D -seam workings. <br />Hole 4 -20L showed a drop of 2.1 feet from the prior year. <br />Hole 33 -8L showed a 1.1 foot rise in the depth to water. This response is similar to the <br />adjacent 33 -8M hole. <br />Monitoring hole 22 -2L was completed in October 2005 for monitoring future mining <br />expansion. This hole recorded a 4.0 foot drop in the water table over the prior year. <br />From the baseline data, all three zones should be classified as "aquitards" in that they will <br />yield water but at very slow rates. Mining in the B Seam so far has encountered only <br />small flows of water and the mine is essentially dry. Typical inflows are in the order of 25 <br />to 30 gpm with occasional short term increases when localized perched water tables are <br />encountered. Water leaking out of caved areas is routed to the sumps at the end of <br />gateroads. No underground water has been pumped out of the mine since the January <br />31, 1996 underground fire. Currently, excess water is pumped from the B -seam to the <br />abandoned D -seam for storage. <br />2.2.1.4 Bedrock Water Quality Water sampling and analysis are no longer required <br />from most of the bedrock monitoring holes. However, as required by DRMS, prior to <br />entering Federal leases C -8424 and C -8425, one water quality sample was collected and <br />analyzed from each of the monitoring holes in federal leases C -8424 and C -8425. Such <br />sampling was limited to the middle (coal facie) zone. <br />BME has agreed to sample the point of compliance monitoring well on an annual basis <br />starting with the 2006 -2007 hydrologic year. The point of compliance for 2007 -2008 was <br />monitoring well 29 -4M. Starting in 2008 -2009 the point of compliance is now monitoring <br />well 22 -3M. Samples are analyzed for dissolved iron and manganese and total dissolved <br />solids. Field parameters measured are pH, conductivity, and temperature. Results for <br />this well are found in Appendix C. <br />The Deserado Mine First Annual Hydrology Report (December 1985) contains baseline <br />water quality data for the bedrock zones except for wells in federal leases C -8424 and C- <br />8425. Baseline water quality data for these wells are given in the Thirteenth Annual <br />
