0 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 for monitoring holes does not go through a <br />treatment facility such as a sediment pond. Run -off from the pads will be filtered through a <br />sediment fence. Design of sediment fences for three drill pad configurations are presented <br />in Volume 8, Drainage Design and Location beginning on page SAE -31. The three typical <br />drill pads are designed on a 3H:1 V slope, 5H:1 V slope and 10H:1 V slope. The typical <br />sediment fence configuration, berms and ditches for the variousslopes and pad sizes are <br />• shown on Maps 8-8. <br />Methane monitoring hole BRL1- GMW -01 (Map 4 -1) will be constructed where the ground <br />surface is on an approximate 1 OH: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 byPR -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:1 V slope. <br />Exploration hole 2010 -2 will be constructed during 2010 where the ground surface is 1 OH: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 />(3) (b) (iii) <br />The entire operations of the Bowie No. 1 Mine and the Bowie No. 1 West Mine are designed to <br />protect surface and groundwater from adverse effects. Both are monitored on the disturbed site, as <br />well as on the permit and adjacent areas. As discussed in Sections 2.05.6(3)(a)(iii), stipulations <br />attached to the Operator's FCL C -37210 require that existing on -tract and cross -tract flows be <br />PR -04 - 113c- 08/10 <br />APP_ 6K <br />1�r3� l I <br />
