Bowie Resources, LLC <br />Bowie No. 2 Mine <br />2013 Annual Hydrology Report Revised May 11, 2015 <br />North Fork Alluvium Monitoring Wells <br />Alluvial monitoring wells AW -1 through AW -6 are located near the mine entrance along <br />the north side of Bowie Road. These wells are monitored quarterly for field parameters <br />and semi - annually for full suite laboratory parameters during the second and fourth <br />quarters in accordance with the permit application. Alluvial monitoring wells AW -7 <br />through AW -9 are located near the mine entrance along the south side of Bowie Road. <br />AW -10 cannot be reliably sampled due to a collapse of the casing, and was eliminated <br />from the monitoring plan. These wells were installed as a requirement of PR -03 which <br />allowed the mine operator to relocate Sediment Pond B to the south side of the <br />highway. Alluvial Wells 11 through 13 were installed during the fall of 2000 to monitor <br />the alluvium in the area where the new coal loadout (PR -06) was constructed. Alluvial <br />well 13 was eliminated by the construction of the unit train loadout. Alluvial well 14 was <br />installed during 2003 west of Pond K. Alluvial wells 15 through 17 were installed during <br />the fourth quarter of 2003 and are located north of Bowie Road below coal mine waste <br />disposal area #2. <br />The 2013 sampling season provides results consistent with probable hydrologic <br />consequences provided in the permit application. Alluvial wells were installed to monitor <br />impacts that mine operations may have on groundwater. AW -1, AW -2 and AW -3 are <br />near the coal stockpile. AW -4, AW -5 and AW -6 are near gob pile No. 1. AW -7, AW -8 <br />and AW -9 are located south of Pond B. AW -11 and AW -12 are below Gob Pile No. 3. <br />AW -14 is down gradient of Pond K. AW -15, AW -16 and AW -17 are below Gob Pile No. <br />2. All of the wells with baseline data have shown quality degradation over the years. <br />The coal pile leachate is likely similar to the water in alluvial wells AW -1, AW -2 and AW- <br />3 since the wells have been in place for a number of years. AW -7, AW -8 and AW -9 are <br />impacted by water seepage from Pond B. AW -11 and AW -12 are impacted by gob pile <br />leachate from Gob Pile No. 3. AW -14 is affected by seepage from Pond K. Alluvial <br />wells 16 and 17 have been affected by seepage from Pond F. <br />The following table presents a comparison baseline data and 2013 averages of the <br />required parameters for groundwater from rule 2.04.7(1)(a)(v). <br />E <br />pH <br />Su <br />TDS <br />mg /I <br />Conductivity <br />umhos /cm <br />Iron Total (TR) <br />Mg /I <br />Manganese (TR) <br />Mg /I <br />AW -1 Ave Baseline <br />7.2 <br />8200 <br />9100 <br />0.41 <br />0.03 <br />AW -1 Ave 2013 <br />7.1 <br />3015 <br />5000 <br />0.57 <br />0.03 <br />AW -3 Ave Baseline <br />7.0 <br />2415 <br />3600 <br />8.23 <br />0.12 <br />AW -3 Ave 2013 <br />7.1 <br />3043 <br />3525 <br />0.84 <br />0.39 <br />AW -5 Ave Baseline <br />7.2 <br />5580 <br />5450 <br />0.11 <br />0.01 <br />AW -5 Ave 2013 <br />7.0 <br />4274 <br />5300 <br />0.22 <br />0.03 <br />AW -6 Ave Baseline <br />7.4 <br />3995 <br />4650 <br />0.31 <br />0.20 <br />E <br />
