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) (A & B) ( 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:1V slope, 5H:1V slope and 10H:1V slope. The typical <br />sediment fence configuration, berms and ditches for the various slopes 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 10H:1V slope. The completion diagram for BRL1- GMW -01 is <br />shown on page SAE -59. <br />Exploration hole P- 1 -03 -03 (Map 4 -1) will be constructed where the ground surface is on an <br />approximate 3H:1 V slope. <br />Exploration holes BRL1 -08 -03 and BRL -08 -04 will be constructed during 2008 where the <br />ground surface is on an approximate 5H:1 V slope. <br />Exploration holes BV -1 and BV -2 will be constructed during 2008 or 2009 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. <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 />protected from the effects of subsidence by limiting coal extraction in buffer zones established by the <br />BLM under Steven's Gulch and East Roatcap Creek, by formulating a water replacement plan for <br />the repair of conveyance of storage systems and the replacement of any water lost from an <br />adjudicated water right, and by maintaining flows for future use. <br />• This plan of collection, recording, and reporting of ground and surface water quality and quantity <br />data is discussed as follows: <br />MR -124 <br />Y9 PP2oV <br />6 �1/ 6 /ZO / 0 <br />113c <br />06/10 <br />
