<br />upper, middle and lower respectively as a matter of simplicity. The Deserado Mine coal seams <br />q`~ are located near the bottom of the Coal and Siltstone Facies (middle zone). Water levels were <br />' i~ measured in the groundwater monitoring piezometers according to the schedule in Appendix A. <br />a~s~~ ,The water level is measured quarterly in QAL-5, and samples collected annually to analyze for <br />' ~Pu,.µ f the ater quality parameters listed in Table 2-1. <br />As a part of the mid-term review technical revision (TR48), BME requested that DMG approve <br />' discontinuing the monitoring of the following wells: <br />' ~. TW2-7U It has remained dry <br />~. TW2-7L It has remained dry <br />n. 2-7U It has remained dry <br />'t 2-7M It has remained dry <br />S. 2-7L It has remained dry <br />(L 35-4U It has remained dry <br />~, 35~L It has remained dry <br />~ RM-1 It has remained dry <br />ry• 35~M This hole is venting methane; presumed dry <br />ic. 36-2U This well is in a sealed, inactive mining area <br />' ~l 36-2L This well is in a sealed, inactive mining area <br />BME also requested that the monitoring frequency be reduced to annual for all bedrock wells <br />and quarterly for alluvial well QAL-5 and the water sampling requirement be annual for QAL-5. <br />DMG approved BME's application on November 10, 1998. These wells were not monitored in <br />' 1998-1999 water year. <br />During October 1984, the Taylor Draw Reservoir facilities were completed and the reservoir <br />began filling with water. The area around the alluvial groundwater holes has become a shallow <br />water mud flat area with the deposition of mud, silt and sand at high reservoir levels. As a <br />' result, alluvial groundwater monitoring holes Qal-1, Qal-2, Qal-3, Qal-4 and Qal-6 have been <br />destroyed and are no longer available for monitoring. Alluvial hole Qal-5 is still being monitored. <br />' During May 1987, longwall panel 1 was mined past the location of 2-12U. The location was <br />subsided and the monitoring hole could no longer provide usable data. Accordingly, Western <br />' Fuels (now BME) submitted an application for a Technical Revision on 6!7/88 to eliminate <br />groundwater monitoring at 2-12U. The Technical Revision was subsequently approved. <br /> <br /> <br />3 <br />1 <br />
