2.05 APPLICATION FOR PERMIT FOR SURFACE OR UNDERGROUND ACTIVITIES -- <br />MINIMUM REQUIREMENTS FOR OPERATION AND RECLAMATION PLANS. <br />2.05.6 Mitigation of Surface Coal Mining Operation Impacts. (Cont'd.) <br />(3)(b)(ii) (Cont'd.) <br />7) Bowie No. 1 Mine Coal Storage Area small area exemption. Located immediately south of <br />the tracks, south of the coal storage area (see Volume 8 Map No. 8 -3). The Operator will <br />use its best efforts to provide an analytical demonstration that the area does not contribute <br />non - compliant sediment loads to the surrounding drainages. A straw bale filter is <br />constructed below the area to provide alternative sediment control. The straw bale filter will <br />be examined periodically and maintained to ensure adequate function at all times. Samples <br />will be analyzed for compliance with the NPDES settleable solids standard. No mixing of <br />surface drainage and underground mine drainage occurs within or results from this small <br />area exemption. <br />8) Methane monitoring holes, exploration holes, and monitoring wells will be drilled over the <br />mine workings. Run -off from the drill pads does not go through a treatment facility such as a <br />sediment pond. Run -off from the pads will be filtered through a sediment fence or straw <br />logs. Straw logs will be a minimum of six inches in diameter. Design of sediment fences for <br />three drill pad configurations are presented in Volume 8, Drainage Design and Location <br />beginning on page SAE -31. Refer to page SAE -30 for a discussion of the straw log <br />substitute for silt fences. The three typical drill pads are designed on 3H:1 V, 5H:1 V and <br />1 OH:1 V slopes. The typical sediment fence configuration, berms and ditches for the various <br />slopes and pad sizes are shown on Map 8 -8. <br />Methane monitoring hole BRL1- GMW -01 (Map 4 -1) will be constructed where the ground <br />surface is on an approximate 10H:1 V slope. The completion diagram for BRL1- GMW -01 is <br />shown on page SAE -59. <br />Exploration hole P- BRL- 1 -03 -01 was be constructed where the ground surface is on an <br />approximate 3H:1 V slope. Liability for exploration hole P- BRL- 1 -03 -01 and associated roads <br />are transferred to the Bowie No. 2 Mine by PR -04. <br />Exploration holes BRL1 -08 -03 and BRL1 -08 -04 were constructed during 2008 where the <br />ground surface is on an approximate 5H:1 V slope. Liability for exploration hole BRL1 -08 -03 <br />and associated roads are transferred to the Bowie No. 2 Mine by PR -04. Liability for <br />exploration hole BRL1 -08 -04 and a portion of the access roads are transferred to the Bowie <br />No. 2 Mine by PR -04. <br />Exploration holes BV -1 and BV -2 will be constructed during 2010 or 2011 where the ground <br />surface is on an approximate 3H:1V slope. <br />Exploration hole 2010 -2 will be constructed during 2010 where the ground surface is 10H:1 V <br />or flatter. Liability for exploration hole 2010 -2 and associated roads are transferred to the <br />Bowie No. 2 Mine by PR -04. <br />Gob Vent Boreholes B -10A and B -10B will be constructed during 2010 where the ground <br />surface is 10H:1 V or flatter. Liability for the two gob vent boreholes and associated roads are <br />transferred to the Bowie No. 2 Mine by PR -04. <br />Exploration holes 2011 -1, 2011 -2 and 2011 -3 will be constructed during 2011 where the <br />ground surface is 1 OH:1 V or flatter. <br />MR -132 - 113c - 10/13 <br />' XXoved <br />
