11. On monitoring point table page 60 of the 1999 AHR, no Fourth quarter full suite <br />monitoring of Sheep Corral surface water D2-1 was taken, although the flow rate was 0.4 <br />gallons per minute. Please explain. <br />12. On monitoring point table page 81 of the 1999 AHR, no fourth quarter full suite <br />monitoring of Steven's Gulch surface water location Steph-low was sampled, even <br />though the flow rate was 0.3 gallons per minute. Please explain. <br />13. On monitoring point table page 88 in the 1999 AHR, there is no full suite sampling for <br />DH-l6 for 1999, even though there is water in the well. Please explain this omission. In <br />addition, the water level recorded in this well for 9/10/99 is over 320 feet higher than just <br />three months before. Please explain. <br />14. The 1999 AHR monitoring point tables for drill holes DH-57, DH-58 and DH-58a show <br />only one sample was analyzed for each monitoring hole during 1999. Table t of the 1999 <br />AHR shows that semi-annual full suite and quarterly field pazameters aze to be sampled. <br />Please explain. <br />15. The footnotes for DH-58 and DH-SSa, on monitoring point table pages 97 and 98 <br />respectively, state that the baseline data was gathered for a period from 1905 to 1997. Is <br />this a misprint or has there been reliable data during that length of time? <br />16. The monitoring point table for TC-up is missing from the 1999 AHR. Please submit this <br />page for inclusion into the report. <br />17. Monitoring point table page 85 shows a flow rate of 50 cubic feet per second for the <br />3/29/99 sample of location TC-west. This appeazs to be a misprint. Please revise if you <br />agree. Also, please explain why there is no full suite analyses for TC-west, even though <br />all quarterly field parameters show flow. <br />1999 Annual Mine Inflow Report <br />BRL reported that the total mine inflow from natural sources averaged less than 10 gallons per <br />minute. BRL also reported that there were no mine water discharges in 1999. <br />Due to completion of the Deer Trail Ditch water metering system, BRL was able to calculate that <br />the consumptive water use at the Bowie No. 2 Mine was about 31 acre-feet of water for every 1 <br />million tons of coal mined. This calculation does not include water loss from pond evaporation, <br />which was estimated to be 2.0 acre-feet per year. At this rate, the consumptive use, not including <br />pond evaporation, for 5 million tons of mined coal per year would equal 155 acre-feet of water. <br />This is less than the estimated consumptive use of 234.6 acre-feet, not including pond <br />
