• 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 /> <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 belowthe 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 <br />a sediment fence. Design of sediment fences for three drill pad configurations are <br />presented in Volume 8, Drainage Design and Location beginning on page SAE-31. The <br />three typical drill pads are designed on a 3H:1 V slope, 5H:1 V slope and 10H:1 V slope. The <br />• typical sediment fence configuration, berms and ditches for the various slopes and pad <br />sizes are 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 <br />is shown on page SAE-59. <br />Exploration holes P-BRL-1-03-03 and WBL-14 (Map 4-1) will be constructed where the <br />ground surface is on an approximate 3H:1 V slope. <br />Gob vent holes GVB-WBUI-C and GVB-WBU3-B will be constructed where the ground <br />surface is on an approximate 10H:1 V and 3H:1 V slopes respectively. <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, <br />as 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 <br />the BLM under Steven's Gulch and East Roatcap Creek, by formulating a water replacement plan <br />for 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 />TR-44 113c 8/04 <br />{t /yRovED <br />8~r6 ~a y <br />
