Bowie Resources, LLC <br />Bowie No. 2 Mine <br />2016 Annual Hydrology Report <br />included herein by reference. <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 2016 sampling season provides results consistent with baseline information <br />provided in the permit application, showing no adverse impact to groundwater during <br />the construction of the mine except for alluvial wells 16 and 17. These two alluvial wells <br />located south of the gob pile have conductivity values significantly higher than baseline <br />conditions. There has not been any significant degradation of alluvial wells 11 and 12 <br />which are located below gob pile #3. <br />Surface Water Monitoring Stations: PONDS <br />Ponds were sampled for water quality when discharging or inflows/outflows were <br />occurring. Ponds are typically spring -fed or seep -fed and exhibit diffuse non - <br />concentrated areas of inflow. Often the pond outlets present the only point of <br />concentrated flow at which flow measurements and field parameters can be obtained. <br />Where possible, quality measurements are obtained at the pond inlet. Stagnant water <br />in ponds is not sampled since water quality results would show the effects of <br />evaporation and stock use and could not be used to evaluate potential mine affects. <br />Ponds are monitored quarterly. The following information is collected for the ponds; 1; <br />inflow; 2) outflow; and 3) water level below spillway outlet or depth of water in pond <br />measured from the bottom of the pond. Field data collected during the 2016 sampling <br />season is consistent with baseline information provided in the permit application. <br />0 <br />
